Aim to evaluate the clinical efficacy of an acetaminophen analgesic by comparing its prescription in fixed versus on-demand schedules after periodontal surgery. The hypothesis of the study was that the fixed regimen would be more effective than the on-demand regimen for postoperative analgesics following periodontal surgery. Methods An open randomized clinical trial was conducted. The 68 patients who needed total flap surgery to restore supracrestal tissue attachment or surgical treatment of periodontitis were randomized”. Visual Analogue Scale was used to assess pain. The fixed group (n = 34) received 500 mg of acetaminophen every 4 hours for 2 days. The on-demand group (n = 34) was instructed to use the acetaminophen “as needed,” at intervals of no less than 4 hours between doses. Ibuprofen was the rescue medication for both groups. Pain scores and medication use were recorded 2, 6, 12, 24 and 48 hours after the surgical procedure. The study was registered at the Brazilian Registry of Clinical Trials under RBR-7wv259. Results The two groups did not differ in relation to the frequency or the intensity of pain in a 48-hour period (n=20 in the fixed group, and n=22 in the on-demand group), or even in the intention-to-treat (n=34 in each group). Individuals who experienced moderate to severe pain used rescue medication more frequently in both groups. No adverse events were reported. Conclusion Both regimens were effective in controlling postoperative pain after periodontal surgery.

Resumo Esse estudo objetivou avaliar a prevalência de perda dentária e fatores associados em adolescentes institucionalizados. Esse estudo transversal incluiu 68 adolescentes do sexo masculino de um Centro de Atendimento Socioeducativo (CASE) com idades entre 15 e 19 anos. Questionários estruturados foram aplicados individualmente para acessar variáveis sociodemográficas, econômicas, médicas, comportamentais e autopercepção de saúde bucal. Todos os dentes presentes foram avaliados pelo Índice de dentes Cariados, Perdidos e Obturados (CPOD). A prevalência de perda dentária foi analisada em indivíduos com ≥1 dente perdido. Associações entre perda dentária e variáveis de exposição foram analisadas por regressão de Poisson com estimativa de variância robusta. A prevalência de perda dentária foi 47,06%. Primeiros molares na mandíbula e maxila e incisivos centrais na maxila foram os dentes mais ausentes. No modelo multivariado, número de dentes cariados esteve associado com perda dentária, e aqueles que faziam uso diário de medicações foram associados a maior perda dentária. Além disso, perda dentária foi associada com cárie dentária e uso diário de medicação. Promoção de saúde bucal e seu tratamento devem ser implementados nessas instituições para reduzir a prevalência de perda dentária nesses adolescentes.

Abstract This study aimed to assess the prevalence of tooth loss and associated factors in institutionalized adolescents. This cross-sectional study included 68 male adolescents incarcerated from Socio-Educational Assistance Center (CASE) aged between 15 and 19 years. Questionnaires were applied individually to assess sociodemographical, economical, medical, behavioral and oral health self-perception variables. All present teeth were evaluated by Decay, Missing, Filling (DMF) Index. The prevalence of tooth loss was analyzed in individuals with ≥1 tooth loss. Associations between tooth loss and exposure variables studied were analyzed by Poisson Regression with robust variance estimation. The prevalence of tooth loss was 47.06%. First molars in the mandible and maxilla and central incisor in the maxilla were the most absent teeth. In the multivariate model, number of decayed teeth, and those that reported daily use of medication were associated with higher tooth loss. Besides, tooth loss was associated with decayed tooth and daily use of medication. Oral health promotion and treatment should be implemented in these institutions to reduce the prevalence of dental loss in these adolescents.
