RESUMO Objetivo: Investigar a intenção materna de amamentar exclusivamente (IMA) e variáveis associadas entre as mulheres no terceiro trimestre de gravidez. Métodos: A coleta de dados foi realizada por meio de entrevista e questionário semiestruturado e autoadministrado, entre dezembro/2018 e novembro/2019. As gestantes (n=653) responderam à escala Infant Feeding Intentions (IFI) testada, traduzida e adaptada para o português do Brasil e ao questionário contendo perguntas sobre variáveis sociodemográficas, biológicas e familiares, bem como relacionadas à gestação, ao aleitamento materno, à assistência à saúde e a hábitos. Foram realizadas análises estatísticas descritivas e de regressão logística múltipla hierarquizada, com nível de significância de 5%, para estimar a associação entre as variáveis independentes e o desfecho. A IMA, medida pela escala IFI, foi dicotomizada pela mediana (<16 ou =16). Resultados: A pontuação média±desvio padrão para a escala IFI foi de 14,4±2,6. Os resultados da análise de regressão mostraram que as gestantes que não tinham intenção de oferecer mamadeira (OR=4,33; IC95% 2,79-6,72) ou não sabiam (OR=1,85; IC95% 1,21–2,82), que planejaram a gestação (OR=1,52; IC95% 1,09–2,12), aquelas que acreditavam que teriam ajuda nos cuidados com o bebê (OR=3,60; IC95% 1,51–8,56) ou que não sabiam (OR=3,97; IC95% 1,26–12,51), bem como aquelas que relataram conhecer as recomendações da Organização Mundial de Saúde sobre amamentação (OR=1,73; IC95% 1.13–2.64) tinham mais chances de mostrar uma IMA muito forte. Conclusões: As gestantes no terceiro trimestre de gestação apresentaram forte IMA. A maior IMA esteve significativamente associada aos determinantes estruturais, contextuais e individuais.

ABSTRACT Objective: To investigate exclusive breastfeeding (EBF) intention and associated variables among women in the third trimester of pregnancy. Methods: The data were collected with a questionnaire for the pregnant women (n=653), from December/2018 to November/2019. They answered the Infant Feeding Intentions (IFI) scale, translated and adapted to Brazilian Portuguese, and a questionnaire on sociodemographic, biological, family, pregnancy, breastfeeding, health care, and habits variables. Descriptive statistics and multiple logistic regression analyses were performed with a 5% significance level, following a multilevel hierarchical model that estimated the association between the dependent and independent variables. The outcome EBF intention measured by the IFI score was dichotomized by the median (<16 or =16). Results: Mean±standard deviation score for the IFI scale was 14.4±2.6 (score 0: very strong intention to not breastfeed at all; score 16: very strong EBF intention up to six months). The results from the regression analysis showed that pregnant women who had no intention to bottle feed (OR=4.33; 95%CI 2.79-6.72) or did not know (OR=1.85; 95%CI 1.21–2.82), those who planned the pregnancy (OR=1.52; 95%CI 1.09–2.12), those who believed they would have help to care for the baby (OR=3.60; 95%CI 1.51–8.56) or did not know (OR=3.97; 95%CI 1.26–12.51), and those who reported knowing the World Health Organization recommendations on breastfeeding (OR=1.73; 95%CI 1.13–2.64) were more likely to show a very strong EBF intention. Conclusions: Pregnant women in the third trimester of pregnancy presented a strong EBF intention. The higher EBF intention score was significantly associated with the structural, setting, and individual determinants.

Aim This cohort study aimed to investigate the exclusive breastfeeding (EBF) prevalence and its association with maternal EBF intention and other variables. Method Pregnant women (n=653) in the third trimester of pregnancy filled out a questionnaire on EBF intention using the Infant Feeding Intentions scale and other variables. After delivery, mothers were contacted by phone at the first (T1; n=467), third (T3; n=333), and sixth (T6; n=217) month of the baby’s life or until breastfeeding was terminated, to collect data on breastfeeding, delivery, the newborn, oral habits, and family variables. The associations between independent variables and the outcomes (EBF prevalence at T1, T3, and T6) were analyzed by simple and multiple logistic regression models (α =0.05). Results EBF prevalence was 81.2% at T1, 64.0% at T3, and 35.9% at T6. Nott use baby bottle (OR=612.59; OR=139.08; OR=15.05) and no pacifier use (OR=2.94; OR=2.78; OR=2.93) were associated with the outcome at T1, T3, and T6, respectively. Other associated variables were strong EBF intention (OR=1.71) at T1; higher birth weight (OR=1.62), childcare support (OR=2.59), maternal age (OR=0.54), being married or having a partner (OR=1.82) at T3; and not returning to work (OR=2.39) at T6. Conclusion The EBF prevalence was high at the first month of the baby’s life and decreased over six months. The EBF intention affected EBF initiation. Variables related to the mother´s demographic characteristics, the baby´s birth weight, the childcare support or the baby bottle/pacifier use were associated with EBF. n=653 n653 n 653 (n=653 delivery T1 T (T1 n=467, n467 n=467 , 467 n=467) T3 (T3 n=333, n333 n=333 333 n=333) T6 (T6 n=217 n217 217 babys s terminated newborn habits α =0.05. 005 =0.05 . 0 05 =0.05) 812 81 2 81.2 640 64 64.0 359 35 9 35.9 OR=612.59 OR61259 OR 612 59 (OR=612.59 OR=139.08 OR13908 139 08 OR=15.05 OR1505 15 OR=2.94 OR294 94 (OR=2.94 OR=2.78 OR278 78 OR=2.93 OR293 93 respectively OR=1.71 OR171 1 71 (OR=1.71 OR=1.62, OR162 OR=1.62 62 (OR=1.62) OR=2.59, OR259 OR=2.59 (OR=2.59) OR=0.54, OR054 OR=0.54 54 (OR=0.54) OR=1.82 OR182 82 (OR=1.82 OR=2.39 OR239 39 (OR=2.39 months initiation mother characteristics bottlepacifier n=65 n65 65 (n=65 (T n46 n=46 46 n33 n=33 33 n=21 n21 21 00 =0.0 8 81. 6 64. 3 35.

ABSTRACT Objective: To determine the prevalence and analyze the variables associated with the use of pacifiers and/or bottles by infants up to 6 months of age. Material and Methods: Data on sociodemographic characteristics, intention to offer pacifier and bottle-feeding, pregnancy and breastfeeding (BF) variables were collected at baseline by interviews and a self-administered questionnaire among pregnant women in the 3rd trimester. After delivery, mother-baby binomials were followed by phone calls at the 1st, 3rd, and 6th months of the baby's life (n=467) to gather information on the type of delivery, baby’s gender, BF in the first hour of the newborn’s life, baby’s weight, mother’s return to work, and oral habits. Association analyses were performed using logistic regression models with a 5% significance level with the pacifier/bottle-feeding use as the outcome. Results: Most mothers (52.5%) reported their babies used bottle-feeding, 48.2% used pacifiers and 33.4% used both of them throughout the 6 months. Intention to offer pacifier and bottle-feeding was reported by 45.0% and 54.8% of the mothers at the 3rd trimester of the pregnancy, respectively. Not living in one’s own residence (OR=1.53; 95%CI: 1.05-2.24) and having the prenatal intention of offering a pacifier (OR=2.50; 95%CI: 1.63-3.83) to the baby were significantly associated with pacifier use. Variables significantly associated with bottle-feeding were mother’s return to work (OR=2.48; 95%CI: 1.54-3.97), baby’s lower birth weight (OR=1.58; IC95%: 1.07-2.33), and prenatal intention to offer bottle-feeding (OR=2.51; 95%CI 1.56-4.04). Conclusion: About half of the babies used pacifiers or were bottle-fed, which were associated with the mother’s prenatal intention to offer them to their babies and socioeconomic factors.

Dental trauma is a public health problem because of its high prevalence rates and treatment costs and for affecting mainly younger individuals. Aim This cross-sectional study aimed to investigate the variables associated with dental trauma and its influence on oral health-related quality of life among 7th-grade students of public elementary schools. Methods The data was collected with semi-structured and self-administered questionnaires and an intraoral clinical examination (n = 204). The variables collected regarded dental trauma, lip coverage, overjet, oral health-related quality of life (Child Perceptions Questionnaire - CPQ11-14 ISF: 8), and sociodemographic profile. Association tests and the Mann-Whitney test were performed at a 5% significance level. Results Dental trauma occurred in 12.3% of students, 94.6% had adequate lip coverage, and the mean overjet was 2.7 mm (±2.0). Sex was the only variable with a statistically significant association with dental trauma (p = 0.021). There was no statistically significant difference in the CPQ11-14 ISF: 8 score between students with and without dental trauma (p = 0.136). Conclusions Dental trauma was significantly associated with sex and did not impact the oral health-related quality of life of the students. individuals crosssectional cross sectional healthrelated related 7thgrade thgrade 7th grade th schools semistructured semi structured selfadministered self administered n 204. 204 . 204) coverage Child CPQ1114 CPQ CPQ11 14 CPQ11-1 ISF 8, , 8) profile MannWhitney Mann Whitney 5 level 123 12 3 12.3 946 94 6 94.6 27 2 7 2. ±2.0. 20 ±2.0 0 (±2.0) p 0.021. 0021 0.021 021 0.021) 0.136. 0136 0.136 136 0.136) CPQ111 CPQ1 1 CPQ11- 12. 9 94. ±2.

Resumo Avaliou-se a influência da técnica obturadora na penetração do cimento AH Plus nos túbulos dentinários, por meio de microscopia confocal de varredura a laser (MCVL), e o impacto na resistência de união do material obturador à dentina, por meio do teste de push out. Raízes de incisivos centrais superiores (n=40) foram preparadas com ProTaper Universal e distribuídas em 4 grupos: Condensação lateral, Compactação vertical, Híbrida de Tagger Modificada e Cone único. Após obturação com guta percha e AH Plus acrescido de fluoresceína 0,01%, as raízes foram seccionadas em slices de 2,0 mm. O primeiro slice de cada terço foi submetido à MCVL e, posteriormente, ao teste de push out. O segundo slice foi analisado em MEV. ANOVA demonstrou diferença estatisticamente significante para as técnicas obturadoras e terços radiculares (p<0,05). Para o percentual de penetração, Tukey evidenciou que compactação vertical (91,77±13,51), Condensação lateral (89,18±10,91) e Híbrida de Tagger Modificada (87,53±15,42) apresentaram os maiores valores, estatisticamente diferentes (p<0,05) da Cone único (78,19±22,46). Na resistência de união (MPa), Condensação lateral (3,42±0,54) e Compactação vertical (3,47±0,53) obtiveram os maiores valores, diferentes (p<0,05) da Híbrida de Tagger Modificada (2,19±0,41) e da Cone único (0,54±0,21), que teve os menores valores. Concluiu-se que as técnicas obturadoras Condensação lateral, Compactação vertical e Híbrida de Tagger Modificada propiciaram maior penetração e resistência de união à dentina intrarradicular.

Abstract The influence of root canal filling techniques on the penetration of AH Plus into dentinal tubules was evaluated using confocal laser scanning microscopy (CLSM) and the impact on the bond strength of the filling material on the root dentin was evaluated using the push-out test. Roots of the maxillary central incisors (n=40) were prepared with ProTaper Universal and assigned to four groups: lateral condensation, vertical compaction, modified Tagger hybrid and single cone. After root canal filling with gutta-percha and AH Plus, along with the addition of 0.01% fluorescein, the roots were cut into 2-mm slices. CLSM was performed on the first slice of each root third, followed by the push-out test. The second slice was analyzed under SEM. ANOVA demonstrated a statistically significant difference between the root canal filling techniques and the root thirds (p<0.05). For percent penetration, Tukey’s test showed that the vertical compaction (91.77±13.51), lateral condensation (89.18±10.91) and modified Tagger hybrid (87.53±15.42) presented the highest values, which significantly differed (p<0.05) from those of the single cone (78.19±22.46). For bond strength (MPa), lateral condensation (3.42±0.54) and vertical compaction (3.47±0.53) had the highest values (p<0.05), while the modified Tagger hybrid (2.19±0.41) and single cone (0.54±0.21) had the lowest. In conclusion, the lateral condensation, vertical compaction and Modified Tagger’s hybrid techniques resulted in greater penetration and bond strength to the intra-radicular dentin.

This study evaluates the effect of two thermoplastic obturation systems (MicroSeal and Obtura II) on bond strength of different sealers to intraradicular dentin. Sixty root canals of human canines were prepared using ProTaper rotary files (crown-down technique) and irrigated with 2.5% sodium hypochlorite and 17% EDTA. The root canals were filled by MicroSeal, Obtura II, or lateral compaction techniques using AH Plus and Epiphany SE. 1.5 mm thick root slices were subjected to the push-out test. ANOVA and Tukey's test showed that the bond strength values (MPa) observed in the groups obturated with MicroSeal (2.96 ± 2.72) and Obtura II (2.68 ± 2.18) did not significantly differ from each other (p > 0.05) but were significantly higher than that observed in the group obturated with lateral condensation (2.01 ± 1.48; p < 0.05). There were no statistically significant differences in strength (p > 0.05) among the root canal thirds (cervical: 2.44 ± 2.03; middle: 2.50 ± 2.27; and apical: 2.70 ± 2.34). Adhesive failures were predominant (60%) in all groups. In conclusion, MicroSeal and Obtura II techniques, using AH plus sealer, increased the resistance to displacement of the filling material, when compared with lateral compaction. Moreover, when used with Epiphany SE, these obturation systems did not affect the bond strength of the material to root dentin.

This study aimed to evaluate, by means of scanning electron microscopy (SEM), the cleaning of flattened root canals, varying irrigation/aspiration protocols during biomechanical preparation. Thirdy human mandibular incisors were distributed into three groups (n = 10) according to the aspiration/irrigation protocols: conventional, conventional + brush, and apical negative pressure irrigation. Irrigation procedure was performed with 5 mL of 1% NaOCl at each change of instrument; final irrigation was conducted with 17% EDTA for 5 min. After biomechanical preparation, the roots were sectioned and prepared for SEM analysis. The images obtained were evaluated under 35× and 1,000× magnification by three calibrated examiners, following a double-blind design. All data were analyzed using Kruskal–Wallis and Dunn’s post hoctests (α = 0.05). Canals wherein the conventional method and apical negative pressure irrigation were employed revealed less debris, statistically different from the conventional + brush group (p < 0.05). Regarding the presence of smears, apical negative pressure irrigation was more effective in cleaning, showing lowest scores (p < 0.05), compared with the other tested protocols. Comparing each root canal third revealed that the apical portion was difficult to clean as all the tested protocols showed similar high scores (p > 0.05), both for the presence of debris and smear layer. In conclusion, although none of the studied irrigation/aspiration protocols have completely cleaned flattened root canals, apical negative pressure irrigation was more effective in smear layer removal, whereas the conventional + brush protocol was the least effective in removing the debris and smear layer.

OBJETIVO: Avaliar a prevalência e a severidade da dor orofacial em gestantes. MÉTODOS: O estudo transversal foi realizado em uma amostra de gestantes em atendimento odontológico em uma faculdade de odontologia. Foi aplicado questionário estruturado com perguntas sobre a auto percepção das condições bucais e a presença e a severidade da dor orofacial sentida na boca ou dentes nos últimos 6 meses. RESULTADOS: Participaram do estudo 80 gestantes e, destas, 58,8% afirmaram ter algum problema nos dentes, 31,3% problema na gengiva, 61,3% gosto ruim na boca e 62,5% mau hálito. Apenas 22,5% não apresentaram nenhum tipo de dor orofacial. As dores mais relatadas foram: dor com líquidos quentes, frios ou doces (56,2%) e dor de dente espontânea (38,8%). Quanto à severidade, as dores de intensidade leve e moderada foram as mais frequentes, mas havia um grupo de 23,8% das gestantes com dores intensas ou muito intensas provocadas por líquidos frios ou quentes e 18,8% na mesma condição em relação à dor espontânea. CONCLUSÃO: Os resultados do estudo mostraram que, apesar da alta prevalência de dor orofacial encontrada, a severidade foi baixa e relacionada a algumas situações específicas.

OBJECTIVE: To evaluate the prevalence and severity of oral pain in pregnant women. METHODS: A cross-sectional study was conducted on a sample of pregnant women who were receiving dental care at a Dental School. A structured questionnaire about self-perception of oral conditions and the presence and severity of orofacial pain in the mouth or teeth in the last 6 months was applied. RESULTS: 80 pregnant women participated in the study and, of these, 58.8% reported having a problem with their teeth, 31.3% periodontal problems, 61.3% bad taste in mouth and 62.5% bad breath. Only 22.5% of pregnant women did not exhibit any form of oral pain. The most frequently reported pains were: pain with hot/cold liquids or sweets (56.2%) and spontaneous toothache (38.8%). With regard to severity, mild and moderate pain were the most frequently reported, but there was a group of 23.8% of pregnant women with severe or very severe pain caused by hot or cold liquids and 18.8% in the same condition in relation to spontaneous pain. CONCLUSION: The results of this study showed that, despite the high prevalence of pain detected in the pregnant women, severity was low and referred to specific situations.

This study assessed the cross-sectional Knoop microhardness and flexural strength of root dentin exposed to different surface treatments with chemical agents after biomechanical preparation. Root canals from human canines were biomechanically treated and divided into eight groups (n=10) to receive one of the following dentin treatments: I. Deionized water (control); II. 5.25% Sodium hypochlorite (NaOCl); III. NaOCl + 10% Sodium ascorbate (SA); IV. SA; V. 2% Chlorhexidine gel (CHX); VI. 37% Phosphoric acid gel (PA) + CHX; VII. PA; and VIII. PA + NaOCl. The roots were sectioned to obtain specimens that were evaluated for cross-sectional Knoop microhardness and flexural strength using a three-point bending test. ANOVA and Tukey’s test were performed. The microhardness in the control group was significantly higher (p < 0.05) than in the groups exposed to chemical agents, which in turn were statistically similar (p > 0.05) to each other. Regarding flexural strength, PA+NaOCl provided statistical higher values than PA+CHX and CHX. However, there was no significant difference between the control group and those groups subjected to surface treatment (p > 0.05). Dentin microhardness was reduced after exposure to NaOCl, CHX, PA, SA and their associations and the flexural strength of radicular dentin was not affected by the chemical agents.

Este estudo avaliou, in vitro, por meio de microscopia óptica e morfometria, a limpeza da região apical em canais radiculares com curvatura leve e moderada submetidos ao preparo biomecânico com sistema rotatório, bem como avaliou a quantidade de material extruído para a área apical. Incisivos laterais (n = 32), sendo 16 com ângulo de curvatura igual ou inferior a 10º (GI) e 16 entre 11º e 25º (GII), foram submetidos à instrumentação rotatória com o sistema Hero 642 com diferentes diâmetros cirúrgicos: (A) 30,02 e (B) 45,02. A irrigação, a cada troca de instrumento, foi realizada com água ultra-pura de Milli Q (5 mL), e o material extruído através do forame apical foi coletado. As raízes foram submetidas a análise histológica sob microscopia óptica (40×) e as imagens foram submetidas à análise morfométrica utilizando o software Image Tool. A quantificação do material extruído foi realizada por pesagem, após a evaporação do líquido. A análise de variância não mostrou diferença estatística significante em relação à limpeza da região apical nos diferentes grupos testados (p>0,05). Considerando a quantidade de material extruído, o teste de T6ukey mostrou que os canais com curvatura leve preparados com o diâmetro cirúrgico 45,02 apresentaram os maiores valores, sendo estatisticamente diferente dos demais grupos (p<0,05) que foram semelhantes entre si (p>0,05). Pode-se concluir que a limpeza da região apical não diferiu entre os diferentes grupos, considerando a curvatura radicular e o diâmetro cirúrgico. A quantidade de material extruído foi maior nos canais preparados com curvatura leve que foram preparados com diâmetro cirúrgico 45,02.

Optical microscopy and morphometric analysis were used in this study to evaluate, in vitro, the cleaning of the apical region in root canals with mild or moderate curvatures subjected to biomechanical preparation with a rotary system, as well as to assess the amount of extruded material to the periapical area. Lateral incisors (n = 32), 16 with curvature angles smaller or equal to 10º (GI) and 16 between 11º and 25º angles (GII) were submitted to Hero 642 rotary instrumentation with different surgical diameters: (A) 30.02 and (B) 45.02. Irrigation was performed at each change of instrument with 5 mL of ultrapure Milli-Q water and the extruded material through the apical foramen was collected. Root cross-sections were subjected to histological analysis by optical microscopy (×40) and the images were evaluated morphometrically using the Image Tool software. Quantification of the extruded material was performed by weighing after liquid evaporation. ANOVA showed no statistically significant differences (p>0.05) among the groups with respect to the procedures used to clean the apical region. Considering the amount of extruded material, the Tukey's HSD showed that canals with mild curvature prepared with the 45.02 surgical diameter showed significantly higher values (p<0.05) that those of the other groups, which were similar between themselves (p>0.05). In conclusion, the effect of cleaning the apical region did not differ in the groups, considering root curvature and the surgical diameter of instruments used for apical preparation. The amount of extruded material was greater in canals with mild curvature that were prepared with the 45.02 surgical instrument diameter.

O objetivo desta pesquisa foi determinar o efeito da adequação do meio bucal sobre a contagem de Streptococcus mutans em gestantes de alto risco à cárie, participantes de um programa de prevenção em uma instituição de ensino público, antes e após adequação do meio bucal. Amostras de saliva de 30 gestantes (18 a 43 anos) que procuraram atendimento na Clínica de Odontologia Preventiva da FOAr-UNESP foram coletadas antes e após procedimentos de adequação do meio bucal, e examinadas para observação e contagem das UFCs de S. mutans. Foi demonstrado que houve diminuição na quantidade das UFCs (p<0,0001) entre as amostras. Em relação à faixa etária, 70,0% das gestantes tinham entre 18 e 30 anos de idade e 30,0% pertenciam à faixa etária de 31 a 43 anos. Dados relativos ao período da gestação revelaram que 73,4% estavam no 2º trimestre e 13,3% estavam igualitariamente no 1º e 3º trimestres. A adequação do meio bucal se mostrou eficaz na diminuição das UFCs de S. mutans presentes na saliva de gestantes de alto risco de cárie. Este procedimento é simples e extremamente efetivo, atendendo às necessidades de tratamento básico de gestantes que procuram atendimento odontológico no serviço público de saúde.

The aim of this study was to determine the effect of oral environment stabilization (OES) on the counting of Streptococcus mutans in high-caries-risk pregnant women participants of a prevention program in a public teaching institution. The sample was composed of 30 pregnant women aged 18 to 43 years, who looked for treatment at the Preventive Dentistry Clinic of the Araraquara Dental School, UNESP. Saliva samples were collected before and after the OES procedures and were forwarded to the pathology for observation and quantification of S. mutans CFU. There was a decrease in the number of S. mutans CFU, which was significantly different (p<0.0001) between samples. Considering the age group, 70.0% were between 18 to 30 years old and 30.0% belonged to the 31-43-year-old age group. Data related to the pregnancy period showed that 73.4% were in the second trimester, 13.3% in the first and 13.3% in third trimester. OES showed to be an effective clinical procedure in diminishing the number of S. mutans CFU in the saliva of high-caries-risk pregnant women. This management is simple and effective, corresponding to the basic treatment needs of pregnant women that search dental care in this public service.

OBJETIVOS: avaliar a percepção das condições de saúde bucal de um grupo de gestantes, através da aplicação do índice General Oral Health Assessment Index (GOHAI). MÉTODOS: participaram do estudo 53 gestantes que freqüentavam uma Unidade Básica de Saúde em Araraquara, São Paulo. Foi aplicado um questionário contendo questões do índice GOHAI, questões sobre a autopercepção das condições bucais e sobre as características sócio-demográficas. Por meio dos testes não-paramétricos Mann-Whitney e Kruskall-Wallis, foram determinados a associação das variáveis sociais e de autopercepção com o índice GOHAI. RESULTADOS: a percepção das condições bucais, medida pelo índice GOHAI, foi positiva e apresentou um valor médio de 31,6. Os dados subjetivos mostram que apenas 12,0% das gestantes classificaram sua condição bucal como "ruim", a maioria declarou nenhum problema dentário, embora 58,7% tenha relatado distúrbios gengivais. As questões como dor e/ou desconforto foram as mais percebidas pelas gestantes. CONCLUSÕES: as gestantes fizeram uma avaliação positiva de sua condição bucal, estando o índice GOHAI associado a variáveis relacionadas à autopercepção. Tal índice pode ser aplicado em grupos populacionais como as gestantes, possibilitando medidas educativas e/ou preventivas direcionadas às suas reais necessidades.

OBJECTIVES: to assess oral healthcare conditions of a group of pregnant women through the application of the General Oral Health Assessment Index (GOHAI). METHODS: fifty three pregnant women clients of the Basic Oral Health Clinic in Araraquara São Paulo were enrolled in the program. A questionnaire with the GOHAI rating questions, questions related to self-perception of oral conditions and to social and demographic characteristics was applied. Through these Mann-Whitney and Kruskall-Wallis non-paramedic tests, the association of social variables and self-perception of the GOHAI rates were determined. RESULTS: oral conditions perception as measured by the GOHAI index was positive and presented a median value of 31,6. Subjective data indicated that only 12,0% of the pregnant women rated their oral condition as "bad", the majority did not disclose any dental problem, although 58,7% reported gum problems. Issues such as pain and/or discomfort were the ones more closely perceived by the pregnant women. CONCLUSIONS: pregnant women had a positive assessment of their oral conditions with the GOHAI rating associated to self-perception variables. This index could be applied to population groups such as pregnant women, enabling educational and/or preventive measures focused on their real needs.

OBJETIVO: Avaliar a autopercepção das condições de saúde bucal por idosos e analisar os fatores clínicos, subjetivos e sociodemográficos que interferem nessa percepção. MÉTODOS: Participaram do estudo 201 pessoas, dentadas, com 60 anos ou mais, funcionalmente independentes, que freqüentavam um centro de saúde localizado em Araraquara, SP, Brasil. Foi aplicado questionário com questões sobre as características sociodemográficas da amostra, a autopercepção da condição bucal e o índice Geriatric Oral Health Assessment Index (GOHAI). Realizou-se exame clínico para determinar a prevalência das principais doenças bucais. Foram usados testes estatísticos para determinar a associação das variáveis sociodemográficas e clínicas e do índice GOHAI com a autopercepção da condição bucal e a identificação dos preditores da auto-avaliação. RESULTADOS: O exame clínico revelou grande prevalência das principais doenças bucais, apesar de 42,7% das pessoas avaliarem sua condição bucal como regular. As variáveis associadas à auto-avaliação foram: classe social, índice de GOHAI, dentes cariados e indicados para extração. A análise multivariada mostrou que os preditores da auto-avaliação foram o GOHAI, os dentes com extração indicada e o índice Community Periodontal Index and Treatment Needs. Esses preditores explicaram 30% da variabilidade da auto-avaliação. CONCLUSÕES: Concluiu-se que a percepção da saúde bucal teve pouca influência nas condições clínicas, mostrando ser necessário desenvolver ações preventivas e educativas para a população.

OBJECTIVE: To assess the self-perception of oral health status of the elderly and to analize the clinics, subjectives and sociodemographic factors that interfer in this perception. METHODS: Results are based on interviews and clinical assessment of 201 subjects aged 60 years and over, who were dentate, functionally independents and used to go to a health care center in the town of Araraquara, SP, Brazil. A questionnaire with questions about social characteristics of the sampled population, their oral health status self-perception and the Geriatric Oral Health Assessment Index (GOHAI) was applied. All subject underwent a clinical examination to determine the prevalence of the main oral diseases. Statistical analyses were performed to determine the association between social and clinic variables, and the GOHAI index with their oral health self-perceptions. In addition, analyses were made to identify self-assessment predictors. RESULTS: The clinical examination revealed that dental caries and periodontal disease had a significant prevalence, though 42.7% of the sample assessed their oral health status as regular. Social class, the GOHAI index, and the decayed and missing teeth were all associated with the self-assessment. The multivariate analysis showed that the self-assessment predictors were the GOHAI index, missing teeth and Community Periodontal Index and Treatment Needs index. These predictors accounted for 30% of the self-assessment variability. CONCLUSIONS: As the oral health self-perception had minor influence on the clinical conditions, developing educational and preventive actions for the elderly population are recommended.

O objetivo deste estudo foi avaliar as condições de saúde bucal em pessoas com 60 anos ou mais no Município de Araraquara, Estado de São Paulo, Brasil, no ano de 1998. Participaram do estudo 194 pessoas (91 institucionalizadas, com idade média de 73,6 anos, e 103 não-institucionalizadas, com idade média de 69,3 anos), que foram examinadas por um cirurgião-dentista, previamente treinado, para determinar a prevalência das principais doenças bucais. Os resultados mostraram um grande número de pessoas edentadas (72% dos institucionalizados e 60% dos não-institucionalizados) e de dentes extraídos (93 e 90%, respectivamente), grande freqüência de bolsas periodontais (57 e 75%) e de próteses inadequadas (80% das próteses em pessoas institucionalizadas e 61% em pessoas não-institucionalizadas). Os resultados mostram o comprometimento da qualidade de vida de grande parte dessas pessoas e indicam a necessidade de maior atenção dos serviços públicos a esse grupo populacional.

This study assessed the oral health of individuals 60 years or older in the city of Araraquara, São Paulo, Brazil, in 1998. Of the 194 people who participated in the study, 91 of them were institutionalized and had an average age of 73.6 years, and 103 were not institutionalized and had an average age of 69.3 years. The study participants were examined by a previously trained oral surgeon who determined the prevalence of the most common oral health problems. The results revealed a large number of edentulous individuals (72% of those institutionalized and 60% of the noninstitution-alized participants) and many persons with extracted teeth (93% and 90%, respectively), as well as a high frequency of periodontal pockets (57% and 75%, respectively) and of inadequate dentures (80% and 61%, respectively). Our results show reduced quality of life for a large proportion of these older individuals, and also indicate that public health services should pay greater attention to this population group.
