Abstract: This in vitro study aimed to evaluate the repair bond strength of resin-modified glass ionomer cement using either the same material or a universal adhesive in the etch-and-rinse and self-etch modes plus resin composite. Twenty-four resin-modified glass ionomer cement blocks were stored in distilled water for 14 d and thermocycled. Sandpaper ground specimens were randomly assigned to three experimental groups according to the repair protocol: resin-modified glass ionomer cement (Riva Light Cure, SDI) and universal adhesive (Scotchbond Universal Adhesive, 3M Oral Care) in etch-and-rinse or self-etch modes and nanohybrid resin composite (Z350 XT, 3M Oral Care). After 24 h of water storage, the blocks were sectioned, and bonded sticks were subjected to the microtensile bond strength (μTBS) test. One-way ANOVA and Tukey's test were used to analyze the data. The failure mode was descriptively analyzed. The highest μTBS values were obtained when the resin-modified glass ionomer cement was repaired using the same material (p < 0.01). In addition, the mode of application of the universal adhesive system did not influence the repair bond strength of the resin-modified glass ionomer cement. Adhesive/mixed failures prevailed in all groups. Repair of resin-modified glass ionomers with the same material appears to be the preferred option to improve bond strength.

ABSTRACT The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others. publications problem uptodate up date classifications context exception (CTFB http//fauna.jbrj.gov.br/, httpfaunajbrjgovbr http //fauna.jbrj.gov.br/ , jbrj gov br (http://fauna.jbrj.gov.br/) 2015 Brazil 80 specialists 1 2024 133691 133 691 133,69 125138 125 138 125,13 82.3%, 823 82 3 (82.3% 102000 102 000 102,00 7.69%, 769 7 69 (7.69% 11000 11 11,00 . 3,567 3567 567 (3,56 2,292 2292 2 292 (2,29 1,833 1833 833 (1,83 1,447 1447 447 (1,44 1000 1,00 831 (83 628 (62 606 (60 520 (52 50 users science health biology law anthropology education others http//fauna.jbrj.gov.br/ faunajbrjgovbr //fauna.jbrj.gov.br (http://fauna.jbrj.gov.br/ 201 8 202 13369 13 133,6 12513 12 125,1 82.3% (82.3 10200 10 00 102,0 7.69% 76 6 (7.69 1100 11,0 3,56 356 56 (3,5 2,29 229 29 (2,2 1,83 183 83 (1,8 1,44 144 44 (1,4 100 1,0 (8 62 (6 60 52 (5 5 http//fauna.jbrj.gov.br (http://fauna.jbrj.gov.br 20 1336 133, 1251 125, 82.3 (82. 1020 0 102, 7.69 (7.6 110 11, 3,5 35 (3, 2,2 22 (2, 1,8 18 (1, 1,4 14 4 ( 82.

ABSTRACT Objective: To compare the pulp vitality of deciduous molars before and after selective caries removal (SCR) or nonselective caries removal to hard dentin (NSCR) over one year, using oxygen saturation percentage (%SaO2). Material and Methods: Deciduous molars with deep occlusal/proximal-occlusal caries lesions were randomized to SCR (n=22) or NSCR groups (n=22). After the caries removal, the teeth were protected with calcium hydroxide cement and restored with composite resin (Filtek Z250). The pulp condition diagnosis was evaluated at baseline, immediately after caries removal, and follow-up (7 days, 1-, 6- and 12-months) by %SaO2. Pulp exposure and pulp necrosis were primary outcomes, and %SaO2 was secondary. Results: Intraoperative pulp exposure occurred in four teeth of the NSCR group (18.2%) and one tooth of the SCR group (4.5%) (p>0.05). Two cases of pulp necrosis occurred in the NSCR group (10%). No difference in %SaO2 pulp was observed in the inter-and intragroup comparison over time (p>0.05). Conclusion: Advantageously, the %SaO2 minimizes preoperatory pulp vitality diagnosis subjectivity before SCR/ NSCR treatments. Furthermore, the pilot study results suggest the pulp response of deciduous molars, when evaluated by clinical, radiographic, and pulp %SaO2 seems not to differ between teeth treated with SCR or NSCR.

RESUMO A investigação teve por objetivo analisar a viabilidade técnica de incorporação do resíduo proveniente do filtro prensa do processo de beneficiamento do carvão mineral (TFP) e de cinzas pesadas (CP) advindos de uma termoelétrica, em massa cerâmica na escala laboratorial. Foram realizados ensaios de caracterização físico-química e de classificação dos resíduos. Posteriormente foram desenvolvidas dez formulações através de planejamento experimental por delineamento de misturas simplex centroide, incorporando esses resíduos a uma massa padrão de cerâmica vermelha. Os corpos-de-prova foram conformados por extrusão sem vácuo e submetidos a tratamento térmico em estufa e queima em forno mufla a 900 °C. As propriedades tecnológicas avaliadas foram: retração térmica linear de secagem e de queima, absorção de água e resistência mecânica à compressão e por fim, foram realizados testes de eflorescência e análise fitotoxicológica. Os resultados de classificação dos resíduos, indicaram esses como não sendo perigoso – Classe II-B – inerte. Os testes físicos dos corpos-de-prova mostram que comparados a formulação base de cerâmica vermelha (STD), as demais formulações obtiveram resultados dentro dos parâmetros técnicos, que podem ser posteriormente realizados em um ensaio de escala industrial. Embora os ensaios mecânicos das provas com incorporação de resíduo ficaram abaixo da formulação base (STD), não se descarta uma prova em escala similar a industrial. No ensaio de eflorescência, observou-se que não houve presença de sais solúveis. E por fim, no ensaio fitotoxicológico, com Allium cepa L. de uma formulação com agregação de todas matérias-primas juntas, apresentou um resultado próximos ao padrão, se mostrando apto a reprodução em escala industrial.

ABSTRACT The investigation aims to analyze the technical viability of addition the waste from the filter-press from the mineral coal treatment process (TFP) and bottom ash from a thermoelectric (CP), in ceramic paste on the laboratory scale. Physical-chemical characterization and waste classification tests were carried out. Subsequently, ten formulations were developed through the mixture design (DoE), incorporating these residues into a standard clay ceramic paste (STD). The samples were formed by extrusion without vacuum and subjected to heat treatment in an oven and fired in a muffle at 900 °C. The evaluated technological properties were: shrinkage of drying and firing, water absorption and mechanical resistance and, finally, efflorescence tests and phytotoxicological analysis were performed. The results of solid waste classification, indicated these as not being dangerous (Class II-B - inert). The technical analysis of the samples show that compared to the clay ceramic standard formulation (STD), the other mixtures obtained results within the technical parameters, which can later be carried out in an industrial scale test. Although the mechanical tests with waste incorporation were below the standard formulation (STD), a test on an industrial scale is not discarded. In the efflorescence test, it was observed that there was no presence of soluble salts. And finally, in the phyto-toxicological test, with Allium cepa L. of a formulation with aggregation of all raw materials, it presented a result marginally similar to the standard, proving itself capable of reproduction on an industrial scale. filterpress filter press TFP (TFP CP, CP , (CP) Physicalchemical Physical chemical Subsequently DoE, DoE (DoE) STD.

Abstract The aim of the study was to investigate the effectiveness of non-invasive and micro-invasive treatments in active enamel carious lesions in high-caries-risk children. Clinical records of children treated in a dental school setting were retrospectively screened for active enamel carious lesions treated non-invasively (topical fluoride applications, oral hygiene instruction, or dietary guidance) or micro-invasively (sealant). The control of active carious lesions was set as the main outcome established by the combination of inactivation and non-progression of the lesions based on Nyvad and ICDAS criteria, respectively. Individual and clinical factors associated with the outcome were analyzed by Poisson regression. The sample consisted of 105 high-caries-risk children with a mean age of 8.3 (± 2.4) years. From a total of 365 active enamel carious lesions, most lesions (84.1%) were active non-cavitated carious lesions (ICDAS scores 1 and 2) and only 15.9% presented localized enamel breakdown (ICDAS score 3). Of these, 72.6% were inactivated and 92.1% did not progress (mean time of 6.5 ± 4.1 months). The prevalence of controlled carious lesions was higher among children older than 6 years (PR:1.43; 95%CI:1.00–2.03; p = 0.04) and in those with better biofilm control (PR:0.99; 95%CI: 0.98–0.99; p = 0.03). Non-operative approaches are effective for controlling active enamel carious lesions. The majority of active enamel carious lesions became inactive and did not progress after treatment. Caries control was associated with older children and better biofilm control. noninvasive non invasive microinvasive micro highcariesrisk high caries risk noninvasively invasively topical applications instruction guidance microinvasively sealant. sealant .

Abstract This systematic review aimed to investigate if there is a better interceptive treatment for palatally displaced canines (PDC) in the mixed dentition stage. The PubMed/MEDLINE, CENTRAL, Scopus, and EMBASE databases were searched for randomized clinical trials related to the research topic. The gray literature and reference lists were also assessed. Network meta-analysis was conducted to analyze the effects of different approaches on PDC eruption. The surface under the cumulative ranking area was calculated to rank the treatments. The certainty of the evidence was evaluated using the GRADE approach. Of the 892 eligible studies, 18 were selected for full-text analysis and 9 for meta-analysis, involving 506 participants and 730 PDC, to compare 9 approaches. The proportion of erupted PDC was significantly higher for all interceptive treatments compared with control (no intervention). Furthermore, the proportion of erupted PDC was higher in patients subjected to rapid maxillary expansion (RME) than those who underwent double extraction of primary canine and primary molar (relative risk (RR) = 2.68 ICr95%: 1.12–9.35). A higher proportion of erupted PDC was found for RME (RR = 3.07 ICr95%: 1.31–10.67), RME plus use of transpalatal arch (TA) plus extraction of primary canine(s) (EC) (RR = 1.43 ICr95%: 1.09–1.95), EC plus use of cervical pull headgear (RR = 1.38 ICr95%: 1.11–1.79), and EC plus use of TA (RR = 1.36 ICr95%: 1.00–1.9) than for EC. RME was most likely to be considered as the best interceptive treatment. Overall, the certainty of the evidence was considered low due to imprecision and indirectness. In conclusion, no intervention in the mixed dentition stage is the worst choice for PDC.

Resumo Nas últimas duas décadas, observou-se um interesse crescente nos estudos de hipomineralização molar-incisivo (HMI). Os defeitos hipomineralizados podem ter várias consequências, como hipersensibilidade, aumento do acúmulo de placa dentária e, consequentemente, maior risco de cárie. Este estudo transversal teve como objetivo investigar a prevalência de HMI e sua associação com cárie dentária em escolares de um município do sul do Brasil. Uma amostra aleatória de alunos por conglomerado foi selecionada. Os exames clínicos foram realizados para coletar informações sobre HMI (seguindo os critérios da European Academy of Pediatric Dentistry), cárie dentária (usando o índice DMF-T) e gengivite. Variáveis socioeconômicas, demográficas e comportamentais foram coletadas por meio de um questionário padronizado respondido pelos pais / responsáveis pelas crianças. Razões de prevalência (RP) foram estimadas por meio de análise de regressão de Poisson com variância robusta por meio de abordagem hierárquica (p <0,05). Um total de 513 escolares foram incluídos no estudo. A prevalência de MIH e cárie foi de 19,7% e 31,6%, respectivamente. A média de idade foi de 11,6 (± 1,9) anos. A cárie dentária foi mais prevalente em crianças com HMI (RP 1,39; IC 95% 1,05 - 1,85). Crianças mais velhas e crianças cujas famílias estavam matriculadas em programas de transferência condicional de renda (RP 1,97 IC95% 1,47 - 2,64), e crianças que não tinham a mãe ou o pai como chefe da família (RP 1,56 IC95% 1,06 - 2,30) apresentaram maior prevalência de cárie dentária. Nossos resultados sugerem que crianças com HMI são mais propensas a ter cárie dentária.
Abstract The last couple of decades has seen an increasing interest in molar-incisor hypomineralization (MIH) studies. Hypomineralized defects can have several consequences such as hypersensitivity, increased dental plaque accumulation, and consequently higher caries risk. This cross-sectional study aimed to investigate the prevalence of MIH and its association with dental caries in schoolchildren from a city in southern Brazil. A random cluster sample of schoolchildren was selected. Clinical examinations were carried out to collect information on MIH (following the European Academy of Pediatric Dentistry criteria), dental caries (using the DMF-T index) and gingivitis. Socioeconomic, demographic and behavior variables were collected using a standardized questionnaire answered by the children’s parents/caregivers. Prevalence ratios (PR) were estimated using Poisson regression analysis with robust variance through a hierarchical approach (p<0.05). A total of 513 schoolchildren were included in the study. MIH and caries prevalence was 19.7% and 31.6%, respectively. The mean age was 11.6 (+1.9) years. Dental caries was more prevalent in children with MIH (PR 1.39; 95% CI 1.05 - 1.85). Older children and children whose families were enrolled in conditional cash transference programs (PR 1.97 95% CI 1.47 - 2.64), and children who did not have their mother or father as the head of the family (PR 1.56 95% CI 1.06 - 2.30) presented a higher prevalence of dental caries. Our findings suggest that children with MIH are more likely to have dental caries.

ABSTRACT Objective: To investigate the influence de two instruments for evaluation of cariogenic foods consumption by schoolchildren. Material and Methods: The convenience sample comprised of 30 active-caries children (7-10 years old) attended in a public dental clinic and their mothers, who have not received dietary orientation before study. A trained evaluator administered the Previous Day Food Questionnaire (PDFQ) to children and other examiner applied the 24-hour dietary recall with mothers. Internal consistency between PDFQ and 24-hour dietary recall regarding frequency of sugar intake was calculated using intraclass correlation coefficient. Bivariate analyses (Mann-Whitney test) were performed to investigate the factors associated with frequency of sugar intake when using both instruments (α=0.05). Results: A moderate correlation (ICC = 0.51; 95%CI: -0.04-0.77; p=0.03) was found between instruments. Mean frequency of sugar intake reported by mothers and children was 3.5 (± 1.8) and 3.7 (± 1.5) times a day, respectively. When using the PDFQ, the frequency of cariogenic foods consumption varied depending on frequency of toothbrushing, i.e., children that had higher frequency of sugar intake brushed their teeth at least two times a day (p=0.016). Conclusion: Previous Day Food Questionnaire applied with schoolchildren could substitute the mothers' reports of cariogenic foods consumption when dietary interventions for controlling dental caries are necessary. If doubts remain regarding the children's response, mothers should be consulted.

ABSTRACT Objective: To compare the root canal preparation of primary teeth with reciprocating and rotary NiTi instruments. Material and Methods: Electronic databases (PubMed/MEDLINE, Web of Science, TRIP, Lilacs, Embase, and Scopus) were systematically searched until October 2020. In vitro studies comparing the cleaning ability, debris extrusion, file deformation, or working time of rotary and reciprocating NiTi instruments in primary teeth were evaluated. Two reviewers independently selected the studies, extracted the data, and assessed the risk of bias. Meta-analyses were conducted using a random-effects model to calculate pooled mean differences between reciprocating and rotary NiTi instruments considering the outcomes: working time (minutes) and debris extrusion (milligrams). Statistical analyses were performed using RevMan 5.3 at a significance level of 5%. Results: From 4,417 potentially relevant studies, 10 were included in the systematic review, and 8 considered in the meta-analyses. There was no significant difference between reciprocating and rotary NiTi instruments considering debris extrusion [3 data sets; effect size: -0.11 (-0.25-0.04); p=0.15] and working time [6 data sets; effect size: -0.37 (-0.98-0.24); p=0.24]. The heterogeneity found was moderate to high. The risk of bias was low in most studies (50.0% of all items across studies). Conclusion: There is no scientific evidence showing superiority of reciprocating or rotary NiTi instruments used for root canal preparation in primary teeth.

Abstract Dentifrices containing different active agents may be helpful to allow rehardening and to increase the resistance of the eroded surface to further acids or mechanical impacts. This study aimed to compare the effects of conventional (sodium fluoride [NaF]) and stannous fluoride (SnF2)-containing dentifrices on reducing erosive tooth wear (ETW). The PubMed/MEDLINE, Scopus, LILACS, BBO, EMBASE, TRIP electronic databases, and grey literature were searched until January 2021 to retrieve relevant in vitro and in situ studies related to research question. There were no restrictions on publication year or language. Two authors independently selected the studies, extracted the data, and assessed the risk of bias. ETW data were pooled to calculate and compare both dentifrices (overall analysis) and in vitro and in situ studies separately (subgroup analysis). Statistical analyses were performed using RevMan5.3 with a random effects model. Of 820 potentially eligible studies, 101 were selected for full-text analysis, and 8 were included in the systematic review and meta-analysis. There was a significant difference between SnF2-containing dentifrices and NaF dentifrices only for in vitro studies (p=0.04), showing a higher effect of the SnF2-containing dentifrices against the erosion/abrasion (effect size: -6.80 95%CI: -13.42; -0.19). Most in vitro and in situ studies had high and low risk of bias, respectively. In vitro literature suggests that the ETW reduction is greater when using SnF2-containing dentifrices instead NaF-containing dentifrices. However, the evidence level is insufficient for definitive conclusions. Clinical trials are necessary for a better understanding of the effect of these compounds on ETW.

Abstract This in vitro study aimed to evaluate the effect of a silane-containing universal adhesive used with or without a silane agent on the repair bond strength between aged and new composites. Forty nanohybrid composite resin blocks were stored in distilled water for 14 d and thermo-cycled. Sandpaper ground, etched, and rinsed speciments were randomly assigned into four experimental groups: silane + two-step etch-and-rinse adhesive system, two-step etch-and-rinse adhesive system, silane + silane-containing universal adhesive system, and silane-containing universal adhesive system. Blocks were repaired using the same composite. After 24 h of water storage, the blocks were sectioned and bonded sticks were submitted to microtensile testing. Ten unaged, non-repaired composite blocks were used as a reference group to evaluate the cohesive strength of the composite. Two-way ANOVA and Tukey’s tests were used to analyze average µTBS. One-way ANOVA and Dunnet post-hoc tests were used to compare the cohesive strength values and bond strength obtained in the repaired groups (α = 0.05). The µTBS values were higher for the silane-containing universal adhesive compared to the two-step etch-and-rinse adhesive system (p = 0.002). Silane application improved the repair bond strength (p = 0.03). The repair bond strength ranged from 39.3 to 65.8% of the cohesive strength of the reference group. Using universal silane-containing adhesive improved the repair bond strength of composite resin compared to two-step etch-and-rinse adhesive. However, it still required prior application of a silane agent for best direct composite resin repair outcomes.

Abstract The aim of this study was to investigate the influence of shortening of etching time for dentin on the restoration survival after selective carious tissue removal in primary molars. This two-arm randomized clinical trial included sixty-two subjects (5–8 year-old) and 100 primary molars presenting moderate dentin carious lesions on occlusal surface. The sample was randomly assigned into groups previously to adhesive application (Adper Single Bond 2; 3M ESPE): etching time recommended by manufacturer (15 s) or reduced (7 s). Resin composite (Filtek Bulk Fill Posterior Restorative; 3M ESPE) was inserted in a single increment for all restorations. Restorations were evaluated at 1, 6, 12, and 18 months using FDI criteria. Survival estimates for restorations’ longevity were evaluated with Kaplan-Meier method. Multivariate Cox regression analysis with shared frailty was used to assess the factors associated with failures (p < 0.05). The etching time did not influence the restorations’ survival (HR 0.35 95%CI 0.11–1.12; p = 0.06). Mean estimated time of survival was 17.6 months (95%CI, 17.2–17.9). The survival rates at the 18-month follow-up were 75.7% and 91.4% (AFR: 16.9% and 5.7%) when primary dentin was acid etched for 15 and 7 s, respectively (log-rank p = 0.06). In conclusion, the etching time for dentin did not influence the clinical behavior of adhesives restorations. However, there was a tendency for better clinical outcome when using etching time of 7 s.

Abstract Objective: To compare the teaching of the pulpectomy in primary teeth among graduate and undergraduate Brazilian dental schools. Material and Methods: From August 2015 to July 2016, an 11-question survey was sent to 44 graduate and 207 undergraduate dental schools. Data obtained were summarized using descriptive statistics. Results: The response rate was higher from graduate (56.8%) than undergraduate (41.1%) courses. Pulpectomy was taught by all participating schools. More than 90% of the undergraduate and graduate courses recommend the use of hand instruments for canals debridement, but the widening of root canals was advised in 69.4% of undergraduate and in 84% of graduate schools. Regarding the irrigatings, 1% sodium hypochlorite as a single irrigating solution was the most taught for both biopulpectomy and necropulpectomy. The iodoform-based Guedes-Pinto paste as the single indication was the preferred root canal filling material in undergraduate schools (30.6%), while the zinc oxide-thickened calcium hydroxide paste as the single option was the most recommended in graduate courses (36%). Endodontic hand file associated with lentulo drill for filling root canals was recommended by most courses. Overall, biopulpectomy was performed in one session, while necropulpectomy led two sessions. Periapical radiograph for diagnosis and final obturation was the most adopted conduct by undergraduate (68.2%) and graduate (72%) schools. Gutta-percha and glass ionomer cement were preferred materials to seal the entrance of the pulp chamber. Conclusion: There was variability in the techniques and materials taught to perform pulpectomy in primary teeth among Brazilian graduate and undergraduate dental schools. Calcium hydroxide paste has been used in similar proportion to iodoform-based paste.

Abstract Objective: To investigate the longevity of endodontic treatments and the survival of endodontic re-treatments performed in primary teeth. Material and Methods: The sample included endodontic treatments and re-treatments conducted in anterior and posterior primary teeth without sedation or general anesthesia among children attending a university dental service. Information collected retrospectively from clinical records was used for analyzing data. The Kaplan-Meier estimator test was used to analyze the longevity and survival of endodontic treatment and re-treatments, respectively. Results: A total of 73 patients with endodontic therapy in primary teeth were included in the study, and 116 teeth were analyzed. After one year, the longevity of endodontic treatments performed on primary teeth was 65.74% with an annual failure rate (AFR) of 34.2%. From 47 endodontic treatment failures, 14 teeth (29.8%) were endodontically re-treated. When the endodontic re-treatment was considered as survival, the longevity of treatments reached 68.06% with 31.9% of AFR after one year of follow-up. There was a significant increase in functional tooth retention in those patients that received an endodontic re-treatment (p<0.001). Retreatment provided an additional mean survival time of 8.3 months. Conclusion: Endodontic treatments performed in primary teeth presented a limited longevity. Endodontic re-treatment is a more conservative alternative for endodontically treated primary teeth that have failed and significantly increase tooth retention.

Resumo Embora o tratamento endodôntico seja amplamente recomendado para polpa dentária comprometida, não há informações sobre os fatores associados ás falhas nos dentes decíduos. O objetivo do trabalho foi avaliar a sobrevida e os fatores associados à falha de pulpectomias realizadas em dentes decíduos por estudantes de odontologia. A amostra foi constituída por pacientes atendidos em um Serviço Odontológico Universitário e necessitaram de tratamento endodôntico em dentes decíduos. O estudo investigou variáveis relacionadas ao tratamento e fatores do paciente potencialmente associados à falha do tratamento. A sobrevivência das pulpectomias foi analisada pelas curvas de Kaplan-Meier seguido do teste de log-rank (p<0,05). A análise incluiu 81 pulpectomias realizadas em 62 crianças (5,6 ± 1,5 anos). A sobrevida atingiu 62,9% em até 12 meses de seguimento. A maioria das falhas ocorreu nos primeiros 3 meses (p<0,001). Os dentes com lesões cariosas no início do tratamento apresentaram mais falhas do que aqueles com restaurações ou história de trauma (p = 0,002). A sobrevida de dentes endodonticamente tratados restaurados com compósito foi maior do que os preenchidos com cimento de ionômero de vidro (p = 0,006). Pulpectomias realizadas em duas ou mais sessões apresentaram mais falhas (p = 0,028). Os pacientes com gengivite apresentaram mais falhas no tratamento endodôntico (p = 0,022). As falhas do tratamento do canal radicular em dentes decíduos foram mais propensas a ocorrer em um curto período de tempo e quando o tratamento foi realizado em dentes com lesões cariosas. O uso de compósito em vez de cimento de ionômero de vidro aumentou a sobrevivência pulpectomias. Sessões repetidas para o tratamento endodôntico e a falta de hábitos de higiene bucal tiveram um efeito negativo sobre os resultados.
Abstract Although endodontic treatment is widely recommended for compromised dental pulp, there is no information regarding the factors associated with failures in primary teeth. The aim of this study was to evaluate the survival and factors associated with failure of pulpectomies performed in primary teeth by dental students. The sample comprised patients treated at a University Dental Service and required endodontic treatment in primary teeth. The study investigated treatment-related variables and patient factors potentially associated with treatment failure. Pulpectomy survival was analyzed by Kaplan-Meier estimator followed by log-rank test (p<0.05). The analysis included 81 pulpectomies performed in 62 children (5.6±1.5 years). The survival reached 62.9% up to 12 months follow-up. Most failures occurred in the first 3 months (p<0.001). Teeth with carious lesions at the start of treatment presented more failures than those with restorations or history of trauma (p=0.002). The survival of endodontically treated teeth restored with composite was higher than the ones filled with GIC (p=0.006). Pulpectomy performed in two or more sessions resulted in more failures (p=0.028). Patients presenting gingivitis had more failures in the endodontic treatment (p=0.022). The failures of root canal treatment in primary teeth were more prone to occur in a short time and when the treatment was performed in teeth presenting carious lesions. The use of composite instead of GIC increased the survival of pulpectomies. Repeated sessions for endodontic treatment and lack of oral hygiene habits had a negative effect on the results.
