Abstract Excessive weight is associated with periodontitis because of inflammatory mediators secreted by the adipose tissue. Periodontal impairments can occur during pregnancy due to association between high hormonal levels and inadequate oral hygiene. Moreover, periodontitis and excessive weight during pregnancy can negatively affect an infant’s weight at birth. Objective This observational, cross-sectional study aimed to evaluate the association between pre-pregnancy overweight/obesity, periodontitis during the third trimester of pregnancy, and the infants' birth weight. Methodology The sample set was divided into 2 groups according to the preconception body mass index: obesity/overweight (G1=50) and normal weight (G2=50). Educational level, monthly household income, and systemic impairments during pregnancy were assessed. Pocket probing depth (PPD) and clinical attachment level (CAL) were obtained to analyze periodontitis. The children’s birth weight was classified as low (<2.5 kg), insufficient (2.5–2.999 kg), normal (3–3.999 kg), or excessive (≥4 kg). Bivariate analysis (Mann-Whitney U test, t-test, chi-squared test) and logistic regression (stepwise backward likelihood ratio) were performed (p<0.05). Results G1 showed lower socioeconomic levels and higher prevalence of arterial hypertension and gestational diabetes mellitus during pregnancy than G2 (p=0.002). G1 showed higher means of PPD and CAL (p=0.041 and p=0.039, respectively) and therefore a higher prevalence of periodontitis than G2 (p=0.0003). G1 showed lower infants’ birth weight than G2 (p=0.0004). Excessive maternal weight and educational levels were independent variables associated with periodontitis during the third trimester of pregnancy (X2[2]=23.21; p<0.0001). Maternal overweight/obesity was also associated with low/insufficient birth weight (X2[1]=7.01; p=0.008). Conclusion The present findings suggest an association between excessive pre-pregnancy weight, maternal periodontitis, and low/insufficient birth weight.

RESUMO Racional: A cirurgia bariátrica pode ter um impacto negativo na estrutura óssea bucal. Objetivo: Verificar o padrão ósseo alveolar por meio de índices radiomorfométricos da radiografia panorâmica e medidas lineares realizadas em radiografias periapicais, em pacientes eutróficas e obesas mórbidas antes e após a cirurgia bariátrica. Métodos: A amostra foi constituída por 31 mulheres com idade de 20 a 35 anos, sendo divididas em dois grupos: grupo obeso (GO-obesas de grau III) e grupo controle (GC-eutróficas). Foram avaliadas 20 eutróficas e 11 obesas mórbidas no pré e pós-operatório de operação bariátrica (seis meses). Índices radiomorfométricos e de placa dentária em ambos os grupos foram avaliados nos tempos T0 (baseline) e T1 (seis meses). Na análise radiográfica foram avaliados o padrão trabecular através da escada visual de Lindh e a perda óssea por meio do cálculo da distância da junção cemento-esmalte à crista óssea, em radiografias periapicais. Já as radiografias panorâmicas mensuram índice da cortical mandibular (ICM), índice mentoniano (IM) e índice panorâmico mandibular (IPM), além do índice de placa de Turesky. Resultados: Houve perda óssea significativa em T1 em pacientes do GO, quando comparada com as eutróficas (p<0,05). O padrão trabecular tornou-se mais esparso após a operação apresentando diferença visual. No índice de placa foi observada ligeira melhora após a operação e os eutróficos mantiveram valores similares ao longo do tempo. Conclusão: Pacientes obesas apresentam maior perda óssea, a qual piora após a operação bariátrica, quando comparada com pacientes eutróficas. O mesmo acontece com o trabeculado ósseo que se torna mais esparso após a operação.

ABSTRACT Background: Bariatric surgery may have a negative impact on oral bone structure. Aim: To verify the alveolar bone pattern through radiomorphometric indices of panoramic radiography and linear measurements performed in periapical radiographs in eutrophic and morbidly obese patients before and after bariatric surgery. Methods: The sample consisted of 31 women aged 20-35 years old, divided into two groups: obese group (GO-obese grade III) and control group (GC-eutrophic). Twenty eutrophic and 11 obese morbidities were evaluated in the pre and postoperative bariatric surgery (six months). Radiomorphometric and plaque indices were evaluated at T0 (baseline) and T1 (six months) times, in both groups. In the radiographic analysis the trabecular pattern through the Lindh visual ladder and the bone loss were evaluated by calculating the distance from the cement-enamel junction to the bone crest in periapical radiographs. Panoramic radiographs were used to measure the mandibular cortical index (ICM), mentonian index (IM) and panoramic mandibular index (MPI), in addition to the Turesky plate index. Results: There was a significant loss of bone in T1 in patients submitted to bariatric surgery, when compared to eutrophic patients (p<0.05). The trabecular pattern became sparser after surgery with a visual difference. The plate index showed a slight improvement after surgery and the eutrophic maintained similar values over time. Conclusion: The standard alveolar bone presents greater bone loss in obese patients and worsens this standard after bariatric surgery when compared to eutrophic patients. The same happens with the trabecular pattern that becomes sparser after bariatric surgery.

La utilización de ordenadores en las clínicas odontológicas ha traído muchos beneficios a los cirujanos dentistas, auxiliándolos en varios aspectos técnicos, administrativos y legales. Este estudio tuvo como objetivo verificar si los cirujanos dentistas, alumnos del curso de postgrado en Ortodoncia e Implantodoncia de la Asociación Brasileña de Odontología (ABO), regional de Araçatuba-SP, hacen uso de ordenador y de la documentación digital en la practica clínica. Fueron invitados a participar del estudio todos los 60 alumnos matriculados en los cursos de Ortodoncia e Implantodoncia de aquella Institución, en el año de 2007 y los que consintieron (n=52) respondieron a un cuestionario auto administrable con preguntas abiertas y cerradas sobre el tema. En cuanto al perfil de los participantes, el 64,5% son del género masculino; un 51,9% tienen entre 30-39 años de edad y el 48,1% se graduaron en los años 90. Un 69,3% afirmaron no haber recibido cualquier noción de informática durante los estudios y el 67,3% utilizan el ordenador en el consultorio, principalmente para la administración del mismo (34,3%). En cuanto al uso del prontuario electrónico un 55,8% relataron utilizar esta tecnología, sin embargo un 44,2% negaron. El 32,7% no creen que los documentos electrónicos que tienen puedan servir como prueba judicial y un 35,7% creen que el prontuário electrónico debe ser archivado por 20 años. Se concluyó que la mayoría de los profesionales hacen uso del ordenador en el consultorio y también el prontuario digital, no obstante no se sienten seguros cuanto a la validad jurídica de este tipo de documentos, desconociendo, hasta el tiempo adecuado para archivar

The use of computers in dental clinics has brought many benefits to dentist, helping them in various technical, administrative and legal. This study aimed to verify whether dentist, students of the post-graduate course in Orthodontics and Implantodontia of the Brazilian Association of Dentistry (ABO), regional Araçatuba-SP, using computers and digital documentation in clinical practice. They were invited to participate in the study all 60 students enrolled in courses of Orthodontics and Implantodontia of those institutions, in the year 2007 and those who consented (n = 52) answered a questionnaire containing questions open and closed on the subject . As the profile of the participants, 64.5% are male, 51.9% are between 30-39 years of age and 48.1% completed the graduation in the 90th. A 69.3% said they didn’t receive any notion of computing during graduation and 67.3% use the computer in the office, mainly for management of the same (34.3%). Regarding the use of electronic record 55.8% reported using this technology, while 44.2% denied. 32.7% do not believe that electronic records that can serve as proof of judicial and 35.7% believe that the electronic records should be archived for 20 years. It follows that most professionals use the computer in the office and also the digital records, but does not feel secure about the legal validity of such documents, unknown, including the appropriate time of its filing
