Epidemiologia

Objectives: This cross-sectional observational and epidemiological study aimed to collect data on the oral health conditions of the prison population in Rio de Janeiro, Brazil. Methods: The Penitentiary Moniz Sodré, part of the Penitentiary Complex of Bangu, houses 1385 male inmates of different nationalities. They were divided into groups according to age: Group 1, prisoners aged 18 to 27 years; Group 2, from 28 to 37 years; Group 3, from 38 to 47 years; and Group 4, from 48 and older. A survey was performed, and the Decayed, Missing, Filled Teeth (DMFT) index was applied. A statistical analysis was conducted, considering a p-value of less than 0.05 as significant. Then, multiple linear regression was implemented to verify correlations among the studied parameters, to adjust for confounders, and to examine predictors of DMFT scores. Results: The average age was 26.95 ± 6.72 years, with 57.7% smokers (n = 720) and 7.7% (n = 96) former smokers. Lung diseases were also relatively common (20.9%). The most frequently reported oral issue was bleeding on probing (37.7%, n = 470), with 100% presenting visible dental plaque and 71.3% dental calculus. Oral hygiene habits showed moderate adherence, with 20.1% brushing their teeth at least once daily and 20.3% flossing; however, only 10.3% reported using fluoride mouthwash. The average DMFT score progressively increased across age groups: Group 1 (age: 18–27): 6.89; Group 2 (age: 28–37): 10.87; Group 3 (age: 38–47): 16; and Group 4 (age ≥ 48): 22.5 (p < 0.0001). Decayed (D) teeth scores showed a moderate increase: Group 1: 2.94 ± 2.74; Group 2: 3.38 ± 2.65; Group 3: 3.11 ± 2.56; Group 4: 3.75 ± 3.1 (p = 0.0029). Missing (M) teeth scores demonstrated a significant increase with age, from 2.74 (±2.84) in group 1 to 18.12 (±7.71) in group 4 (p < 0.0001), whereas Filled (F) teeth scores were highest in group 3 (mean 1.92 ± 4.13), followed by a decline in the oldest group (mean 0.62 ± 1.18) (p < 0.0001). These findings indicate a strong age-related increase in the total DMFT score, primarily driven by the number of missing teeth. Conclusions: High levels of caries and its sequelae exist, demonstrating a correlation with age, as well as a low level of previous periodontal treatment or intervention. As the treatments performed did not manage to reduce the incidence of caries and periodontal diseases, a high number of extractions were observed in patients in confinement. Full article
