Self-reported questionnaire on periodontal condition validated for use in Brazil.

There is a current expectation of instruments for periodontal condition surveillance worldwide. The present study aimed to validate the Oral Health Questions Set B (OHQB) for the Brazilian Portuguese and evaluate its temporal stability. This is a sequential mixed-method investigation. After the forward-backward translation process to the Brazilian Portuguese, the OHQB Brazil (OHQB-Br) was applied to 156 participants (39.5 ± 14.14 years; 51.9% males). In sequence, through a full-mouth six-sites/teeth examination and in accordance with the original instrument, the periodontal diagnosis was obtained (March 2020). In January 2021, the OHB-BR was reapplied (n = 71). Ordinal alpha and McDonald's omega tested the internal consistency of the OHQB-Br. Temporal stability was investigated [Spearman correlation, intraclass correlation coefficient (ICC), and the Bland-Altman]. The concurrent validity was also verified, considering the periodontal clinical diagnosis (Kruskal Wallis). The ordinal alpha (0.69) and McDonald's omega (0.73) coefficients showed an adequate internal consistency of the OHQB-Br. The OHQB-Br temporal stability was high, as demonstrated by the Spearman coefficient (0.80) and ICC (0.79) and by the Bland-Altman plot. A concurrent validity showed a direct relationship between the OHQB-Br and the clinical condition of no periodontitis, mild, moderate, and severe periodontitis (p < 0.05). Because the OHQB-Br shows internal validity, temporal stability, and adequately identifies periodontal health and moderate/severe periodontitis, the instrument might represent an important tool, at the public level or other settings, for periodontal surveillance in Brazil.

Self-reported questionnaire on periodontal condition validated for use in Brazil

Abstract: There is a current expectation of instruments for periodontal condition surveillance worldwide. The present study aimed to validate the Oral Health Questions Set B (OHQB) for the Brazilian Portuguese and evaluate its temporal stability. This is a sequential mixed-method investigation. After the forward-backward translation process to the Brazilian Portuguese, the OHQB Brazil (OHQB-Br) was applied to 156 participants (39.5 ± 14.14 years; 51.9% males). In sequence, through a full-mouth six-sites/teeth examination and in accordance with the original instrument, the periodontal diagnosis was obtained (March 2020). In January 2021, the OHB-BR was reapplied (n = 71). Ordinal alpha and McDonald's omega tested the internal consistency of the OHQB-Br. Temporal stability was investigated [Spearman correlation, intraclass correlation coefficient (ICC), and the Bland-Altman]. The concurrent validity was also verified, considering the periodontal clinical diagnosis (Kruskal Wallis). The ordinal alpha (0.69) and McDonald's omega (0.73) coefficients showed an adequate internal consistency of the OHQB-Br. The OHQB-Br temporal stability was high, as demonstrated by the Spearman coefficient (0.80) and ICC (0.79) and by the Bland-Altman plot. A concurrent validity showed a direct relationship between the OHQB-Br and the clinical condition of no periodontitis, mild, moderate, and severe periodontitis (p < 0.05). Because the OHQB-Br shows internal validity, temporal stability, and adequately identifies periodontal health and moderate/severe periodontitis, the instrument might represent an important tool, at the public level or other settings, for periodontal surveillance in Brazil.

Comparison Between Hand and Sonic/ Ultrasonic Instruments for Periodontal Treatment: Systematic Review with Meta-Analysis.

AIMS: To systemically review the literature on the effect of hand and sonic/ultrasonic instruments used for the non-surgical treatment of periodontitis. MATERIALS AND METHODS: Five databases were searched for randomized clinical trials that compared the results of periodontal treatment using hand and sonic/ultrasonic for nonsurgical periodontal treatment. Four meta-analyses were performed, using the calculated mean differences (MD) between baseline and 3-months or 6-months after periodontal treatment for clinical attachment level (CAL), and probing pocket depth (PPD). RESULTS: Eighteen studies were included. All included studies showed significant improvement, in at least one periodontal parameter, in both tested periodontal therapies. The sonic/ultrasonic instruments spend significantly less time in comparison to manual instrumentation. At both 3- and 6-months after periodontal therapy, no statistically significant differences were detected for CAL gain between therapies (MD; 95%CI: 0.05; -0.21-0.30 and -0.23; -0.59-0.12). Similarly, no statistically significant differences were detected for PPD reduction between therapies at 3-months of follow-up (MD; 95%CI: -0.03; -0.34-0.28). After 6-months, the PPD reduction was 0.21 (95%CI: -0.43-0.00, p=0.05). CONCLUSION: Similar results may be expected for the periodontal treatment performed with hand and sonic/ultrasonic instruments. However, further studies with lower risk of bias are warranted.

Avaliação da idade óssea por meio da maturação das vértebras cervicais de indivíduos em crescimento / Assessment of bone age by the maturation of cervical vertebrae of individuals growing

Este estudo avaliou o Estágio de Maturação das Vértebras Cervicais (EMVC), de 150 indivíduos brasileiros de ambos os sexos, com idades entre oito e 14 anos, buscando determinar o dimorfismo sexual e a aplicabilidade do EMVC na clínica ortodôntica. Foram analisadas telerradiografias em norma lateral, obtidas previamente ao tratamento ortodôntico, e a amostra foi dividida em oito grupos, considerando a idade em meses e o gênero. A morfologia das vértebras C3 e C4 foi avaliada por um examinador que indicou o EMVC encontrado para cada indivíduo estudado. Os resultados foram submetidos a testes de qui quadrado e o coeficiente de relação intraclasse avaliou o erro intraoperador. O estudo indicou que a maioria da amostra, apresentava se em EMVC II e EMVC III (p<1%), estágios que representam o surto de crescimento puberal e também o período mais favorável para a terapia ortodôntica. Os resultados também apresentaram que o sexo feminino atinge de forma mais precoce EMVC IV e EMVC V (p<1%), demonstrando que as meninas atingem o surto puberal em idade mais tenra e concluem seu crescimento puberal aproximadamente dois anos antes dos meninos

This study evaluated the Cervical Vertebrae Maturation Stage (CVMS), of 150 Brazilian subjects of both genders, with 8 to 14 years old. The norma lateral telerradyographs had analised, previously to orthodontic therapy, and the sample was divided in eight groups, considering age in months and gender. The C3 and C4 vertebrae morphology, was evaluated by a examiner who indicated the CVMS scored by each subject studied. The results was submitted by chi-square tests and ICC tests avaliated the intraoperator error. The study showed a majority of the sample in CVMS II and CVMS III (p<1%), stages who represents the puberty growing peak and also the most important period to orthodontic therapy. The results showed that the females get in a smaller age the CVMS IV and CVMS V (p<1%), showing that the girls has the puberty peak in a younger age and finish her puberty grow approximately two years before boys

Sulcoplastia mandibular com enxerto de pele / The vestibuloplasty with skin graft

A sulcoplastia com enxerto de pele é uma alternativa que pode ser empregada em situaçöes em que o rebordo mandibular apresenta-se atrófico ou ausente, sendo realizada, na maioria dos casos no segmento anterior da mandíbula. No presente trabalho, os autores realizam uma breve revisäo da literatura e descrevem um caso clínico onde foi realizada esta técnica, discutindo as vantagens e desvantagens da mesm
