Purpose: To evaluate the periodontal condition of adult patients attending public health centres in the city of Recife, Brazil, and to investigate whether periodontal conditions are associated with socioeconomic and demographic variables.
Materials And Methods: This cross-sectional study included 13 randomly selected public health centres. Sample size was calculated using 5.0% standard error and a confidence interval of 95%. The minimum sample size was 461 subjects, and a total of 505 subjects participated in this study. Each participant completed a questionnaire and underwent periodontal examination. Periodontal conditions were based on the Community Periodontal Index (CPI). Bivariate analysis of frequencies and means was performed with SPSS, version 11.0. The chi-square and likelihood ratio statistical tests were used to calculate the level of statistical significance of the associations tested. The level of statistical significance was set at P < 0.05.
Results: Calculus was the highest CPI score in 61.8% of the subjects, and shallow pockets (4-5 mm) were the highest score in 15.2% of them. A healthy periodontium was observed in 10.7%, while gingival bleeding and deep pockets (> or = 6 mm) were found as the highest CPI score in 10.3% and 2.0% of the sample, respectively. Periodontal conditions showed significant association with the socioeconomic and demographic variables analysed (P < 0.05).
Conclusions: Findings indicate a high prevalence of periodontal alterations in the sample. Periodontal conditions were worse in men, married individuals, older subjects and individuals with low socioeconomic class and poor education.

Periodontal disease is a major contributor to tooth loss worldwide in adults. Particularly, periodontal bone defect is a common clinical condition, yet current therapeutic strategies exhibit limited effectiveness. Recently, natural bone graft materials have attracted considerable interest for enhancing bone defect repair due to their superior biocompatibility and osteogenic capabilities.

Background: To investigate the effect of rheumatoid arthritis (RA) on the incidence of peri-implantitis (PI) and peri-implant mucositis (PIM).
Methods: Radiographic and clinical chart reviews were conducted to measure the probing depth (PD), bleeding on probing, and marginal bone loss (MBL) around the implants to diagnose peri-implant diseases based on the 2017 workshop classification. Values were recorded at the baseline (T0) to the last available chart and radiograph (T1).
Clinical management of hereditary gingival fibromatosis: Case report with 13 years follow-up.

Dentistry School, Federal University of Minas Gerais, Belo Horizonte, Brazil.
Background: Hereditary gingival fibromatosis (HGF) is one of the categories of non-plaque-induced gingival diseases of genetic origin. Current studies show high genetic heterogeneity and suggest that not all forms of HGF are the same and that more than one biological mechanism may result in gingival growth. This report presents a case of syndromic HGF with generalized and complex clinical manifestations associated with other conditions such as body hypertrichosis and hearing deficit.

Background: Gingival recession has a multifactorial etiology, involving various predisposing and precipitating factors. Non-carious cervical lesions (NCCLs) are often associated with gingival recession and pose challenges due to their complex pathodynamics. There is limited evidence regarding tunnel-based procedures combined with connective tissue grafts (CTGs) for treating recession-associated NCCLs.
