Objective The aim of this cross‐sectional study was to evaluate the association between periodontitis and different severities of chronic kidney disease (CKD) in predialytic patients. Materials and Methods Demographic, socioeconomic, and medical data of 139 patients from the nephrology service of one university hospital in Porto Alegre, Brazil, were obtained through interview and clinical records. Full‐mouth six‐sites per tooth periodontal examinations were performed. Associations between periodontitis, stages of CKD, and estimated glomerular filtration rate (eGFR) were estimated by multivariable models adjusted for sex, smoking, vitamin D supplementation, physical activity, and renal treatment duration. CKD was classified based on eGFR (<60 ml/min/1.73 m2) estimated by the Chronic Kidney Disease Epidemiology Collaboration equation. Results Patients with severe periodontitis, compared to those without severe periodontitis, had 2.8 (95% CI: 1.25–6.62) and 3.4 (95% CI: 1.27–9.09) times higher risk of being in stages 4 and 5 of CKD, respectively. Having ≥ 2 teeth with clinical attachment loss (CAL) ≥6 mm increased 3.9 times the risk of being in stage 5 of CKD. Patients with severe periodontitis and ≥2 teeth with CAL ≥ 6 mm had 4.4 ml/min/1.732 and 5.2 ml/min/1.732 lower eGFR (p‐values < .05), respectively. Conclusion Severe periodontitis was associated with poor renal conditions in predialytic CKD patients, strengthening the importance of periodontal evaluation in such patient population.

Objectives: This study aimed to evaluate the effect of photobiomodulation therapy (PBMT) on patient morbidity and donor site healing after free gingival graft (FGG) harvesting.Methods: Forty-four patients requiring FGG were selected for this trial. Individuals were randomly assigned to test group (PBMT, n = 22) or control group (placebo, n = 22) applied immediately after surgery, 24 and 48 h after. Demographic, surgicalrelated and psychosocial variables possibly associated with treatment response were collected. The primary outcome was postoperative pain at the donor site evaluated using Visual Analog Scale (VAS) immediately after surgery and 6, 24, 48 and 72 h after. Secondary outcomes include medication consumption, patient-reported outcome measures (PROMs) and percentage of wound closure.Results: Intragroup analysis showed no differences in VASLOG means for placebo group throughout the study (p > .05), whereas a significant difference in PBMT group at 6 h, 24 h, 48 h and 72 h (p < .05) were observed. Postoperative rescue analgesic requirement was significantly higher in the placebo group (p = .004). The number needed to treat(NNT) was 2.43. PBMT group reported significant better function related to sleeping, going to work/school and daily routine activities, less restriction to mouth opening, chewing and food consumption, less swelling and bleeding (p < .05), mainly in the first 48 h. PBMT group presented a significantly higher palatal wound closure at 7 days compared to placebo group (33.41 vs. 21.20 respectively, p = .024) after adjustment for confounding. No adverse effects were reported.Conclusions: Photobiomodulation therapy accelerated the pain resolution time and palatal closure, decreased rescue medication consumption and significantly improved patient satisfaction in the postoperative period.

Xeroradiography, which permits simultaneous demonstration of bone, cartilage and soft tissue, is particularly suitable for planning of facio-maxillary operations.

Objetivo: Descrever as condições de saúde bucal e hábitos comportamentais relacionados à saúde de indivíduos com doença arterial coronariana crônica (DAC) em acompanhamento em uma unidade de atendimento cardiológico do Hospital de Clínicas de Porto Alegre. Materiais e Métodos: Foram avaliados 100 pacientes consecutivos que frequentaram a unidade entre junho de 2011 e março de 2012. Dados demográficos, socioeconômicos e comportamentais foram obtidos. Um exame bucal foi realizado avaliando os índices de placa visível (IPV) e sangramento gengival (ISG), recessão gengival (RG), profundidade de sondagem (PS), sangramento à sondagem (SS) e perda de inserção (PI), além do índice CPO-D. Resultados: Observou-se um predomínio de indivíduos do gênero masculino, sendo que a faixa etária predominante foi a partir de 60 anos na amostra do estudo. Cerca de metade dos indivíduos era ex-fumante. Mais de três quartos da amostra relatou visitas ao dentista de maneira irregular. Os parâmetros relacionados ao biofilme supragengival apresentaram médias elevadas, contabilizando índices de placa e sangramento médios de cerca de 68% e 47%, respectivamente. Mais da metade dos dentes examinados possuíam PS ≥4 mm, e o sangramento subgengival (SS) esteve presente em aproximadamente três quartos dos sítios examinados. A maior parte dos dentes examinados apresentou PI ≥6 mm. Em média, os indivíduos do presente estudo apresentaram 13,2 dentes perdidos. O CPO-D médio encontrado foi de 10,9 dentes. Conclusão: A presente amostra apresentou condições de saúde bucal compatíveis com a epidemiologia das doenças bucais mais prevalentes na população brasileira. Porém, esta condição é alarmante no contexto de saúde, uma vez que cada vez mais tem-se associado perda dentária e doenças periodontais a maiores riscos de eventos cardiovasculares.
