Background The aim of this study was to evaluate the association between systemic non‐communicable diseases (NCDs; including lung, kidney, mental and cardiovascular diseases, arthritis, cancer and spinal problems), common risk factors, and tooth loss (TL), as an endpoint of prevalent oral NCDs (periodontitis and caries). Methods A total of 60,271 noninstitutionalized adults (≥30 years) were evaluated, using data from the 2019 Brazilian National Health Survey. Negative binomial regressions were performed, adjusting for sex, age, ethnicity, educational attainment, oral hygiene, risk factors for periodontitis and caries (diabetes, smoking, and a cariogenic diet). The dependent variable was TL expressed as a numerical value. Results Diabetes, current smoking and a frequent cariogenic diet were significantly associated with TL–Incidence Rate Ratio (IRR [95% CI]): 1.11 (1.08 to 1.14), 1.28 (1.25 to 1.31), and 0.97 (0.94 to 0.99), respectively. Significant associations were observed for TL and all assessed NCDs, except kidney diseases, cancer and musculoskeletal diseases related to work, with IRR ranging from 1.06 for hypertension and asthma to 1.16 for rheumatoid arthritis. Regular consumption (4 to 7 d/wk) of vegetables, fruits and beef; alcohol up to 8 doses/wk; and physical exercise were associated with a lower IRR for TL (P < 0.05). Obesity, but not overweight, was associated with increased TL (1.05 [1.03 to 1.07]). Smoking, hypertension, arthritis, other mental diseases and spinal problems further increased the IRR for TL in individuals with diabetes (P < 0.05). Conclusion We conclude that certain chronic systemic conditions are associated with TL in Brazilian adults. This is likely because of shared risk factors; however, causal associations cannot be examined in this cross‐sectional dataset.
Within the limits of this study, it can be concluded that pulp clinical involvement with a negative response to thermal cold and electric testing occurs only in the most advanced stage of chronic periodontitis with apical involvement.
Background Ozone is a molecule that plays an important role in dentistry, specially for wound healing. The aim of the present study was to clinically and immunologically evaluate the effect of ozonated oil on the healing of palatal wounds. Methods This is a prospective, longitudinal, triple‐blind, randomized, placebo‐controlled clinical trial. The groups were divided as follows: Test group (n = 14): after removal of the free gingival graft (FGG), the palatal wound was treated with ozonized seed sunflower oil with a peroxide index between 510 and 625 meq O2/kg; Control group (n = 14): after removal of the FGG, the palatal wound was treated with non‐ozonated sunflower oil (placebo). The treatments were applied three times a day, for 7 days. Results There were no significant differences in the measurements of wound area (mm2) between the test and control groups in the different periods evaluated (0, 3, 7, and 14 days; p > 0.05). The intra‐group analysis showed a significant decrease in wound size over the course of days (0, 3, 7, and 14 days; p < 0.05). Vascular endothelial growth factor (VEGF; pg/mL) presented a significant reduction at 7 days (p < 0.05) compared to day 3 in the test group (p < 0.05). There was a statistical difference for malondialdehyde (MDA; pg/mL) in the test group between 3 and 7 days post‐treatment (p < 0.05) and between test and control groups on the 7th day (p < 0.05). Conclusions The application of highly ozonated sunflower oil did not improve the remaining scar area of the palate, decreasing the VEGF and increasing the oxidative stress marker MDA.
• Os autores declaram que não há conflito de interesse. ResumoObjetivo: o objetivo deste trabalho foi realizar uma revisão da literatura sobre a utilização das imagens de tomografia computadorizada na Periodontia, para determinar a extensão e gravidade das lesões periodontais, motivando o desenvolvimento de um novo conceito para diagnóstico e planejamento cirúrgico periodontal. Material e Métodos: foi realizada uma busca na literatura na base de dados PubMed, usando as palavras chave tomografia computadorizada, diagnóstico, periodontia, defeitos ósseos, lesões de furca, biótipo periodontal. Trinta e três artigos foram incluídos. Resultados: os artigos revisados sugerem benefícios no uso dessa tecnologia para o planejamento cirúrgico periodontal, no tratamento de lesões de furca, defeitos ósseos, determinação do biótipo periodontal. Conclusão: as imagens tridimensionais da tomografia computadorizada são superiores às radiografias convencionais e também minimizam a exposição do paciente à radiação ionizante, otimizam o planejamento cirúrgico e reduzem o tempo operatório, o que pode proporcionar uma melhor resposta ao tratamento. A utilização desta tecnologia é muito útil na prática clínica, mas ainda pouco difundida em Periodontia, devendo ser amplamente divulgada entre os profissionais.Palavras-chave: Tomografia computadorizada; Diagnóstico; Periodontia. IntroduçãoO diagnóstico em Periodontia, para o planejamento cirúrgico, baseia-se no exame clínico e na complementação radiográfica para visualização de defeitos ósseos, envolvimentos de furca e relação entre crista óssea e junção cemento esmalte. A sondagem, para determinação de profundidade de bolsa e nível de inserção clínico, é estreitamente dependente de fatores como inflamação do tecido, força da sondagem e angulação da sonda, e essas medidas podem subestimar a extensão de defeitos ósseos. 1Exames radiográficos convencionais apresentam uma deficiência no diagnóstico preciso, por não permitirem a avaliação tridimensional das estruturas, podendo prejudicar o planejamento cirúrgico. No passado, para o tratamento cirúrgico em Periodontia, a anatomia da região era reconhecida somente por meio de cirurgias exploratórias e a decisão da conduta a ser tomada, no transcirúrgico, dependia da anatomia encontrada. Atualmente, a Tomografia Computadorizada de Feixe Cônico (TCFC) é uma ferramenta fundamental para um melhor diagnóstico e estabelecimento de um plano de tratamento adequado, otimizando o tratamento de defeitos ósseos, defeitos de furca e cirurgias estéticas. 2,3 O objetivo deste trabalho foi realizar uma revisão de literatura sobre a utilização das imagens de tomografia computadorizada na Periodontia, para determinar a extensão e gravidade das lesões periodontais, motivando o desenvolvimento de um novo conceito para diagnóstico e planejamento cirúrgico.

Introduction Pulp and periodontal tissues may communicate and, in pathological situations, combined endodontic-periodontal lesions may be established. Objective The aim of this study was to evaluate the prevalence of endo-perio lesions in non-molar and molar teeth referred for endodontic treatment. Material and method The sample consisted of 104 teeth evaluated in 79 consecutive patients in a cross-sectional design. Visible plaque, probing depth, and bleeding on probing were evaluated. Endodontic evaluation included the presence or absence of caries, fistulas, pain, and pulp sensitivity. The presence/absence of periapical lesion, bone loss in the furcation region, and proximal area were evaluated. Result The results showed that pain was the main reason for seeking dental care in 63.3% of patients. The molar teeth demonstrated higher presence of probing depth (PD) ≥ 7 mm (38.3%) and higher PD mean (6.17 mm) than non-molar teeth (P<0.05). It was verified that 65.4% of the teeth were diagnosed with a primary endodontic lesion and that the periodontal component was present in 34.6% of the teeth, either in a primary (10.6%), secondary (11.5%), or combined form (12.5%). True combined endodontic-periodontal lesion occurred significantly in molar teeth compared to non-molar teeth (p<0.05). Conclusion The primary endodontic lesion was found in a greater proportion in teeth referred for endodontic treatment; however, approximately 1/3 of the sample had periodontal involvement, which demonstrates the importance of the periodontal examination together with the general clinical examination.
