Abstract in Portuguese
O objetivo deste estudo foi avaliar o efeito de um programa antitabágico e do tratamento periodontal não-cirúrgico na perda dentária em fumantes portadores de periodontite crônica. Fumantes que desejavam parar de fumar se inscreveram no serviço oferecido pelo Programa de Cessação de Tabagismo do Hospital Universitário em São Paulo. Eles se submeteram a tratamento periodontal não cirúrgico concomitantemente à terapia de cessação de tabagismo. Manutenção periodontal foi realizada a cada três meses até 24 meses de acompanhamento. Um examinador calibrado e cego para o hábito de fumar realizou exame periodontal completo na inclusão dos pacientes e após 3, 6, 12 e 24 meses após o término do tratamento periodontal. Este examinador verificou a perda dentária durante o período de acompanhamento. Durante os 24 meses no estudo, a decisão da extração dentária era tomada por um consenso de três periodontistas do grupo de pesquisa. Dos 1.214 pacientes inscritos, 306 foram examinados, 112 foram incluídos e 59 continuaram no estudo por dois anos. Destes, 18 (31%) pararam de fumar e 41 (69%) continuaram fumando ou oscilaram. A média geral do número de dentes perdidos foi 0,63 (±1,4). Após ajustar para as extrações realizadas durante a fase de tratamento periodontal, a média diminuiu para 0,42 (± 1,2), sendo 0,39 ± 0,8 no grupo dos que pararam de fumar e 0,44 ± 1,3 no grupo que continuou fumando (p = 0.88). Apesar de a extensão cumulativa e a média dos dentes ausentes terem sido semelhantes nos dois grupos durante o acompanhamento, houve uma tendência de maior perda dentária no grupo fumante no primeiro ano de acompanhamento. Com estes resultados, verificou-se que a cessação to tabagismo não promoveu um benefício adicional na perda dentária em fumantes 24 meses após parar de fumar.

Abstract in English
The aim of this study was to evaluate the effect of a smoking cessation program and non surgical periodontal treatment on tooth loss in smokers with chronic periodontitis. Smokers willing to quit smoking enrolled in the service offered by the Smoking Cessation Program at the University Hospital in São Paulo. They have undergone non surgical periodontal treatment concomitantly to smoking cessation therapy. Periodontal maintenance was performed every 3 months until 24 months of followup. A calibrated examiner, blinded to smoking status, performed complete periodontal examination on baseline and after 3, 6, 12 and 24 months after periodontal treatment. The examiner assessed tooth loss during follow-up. During the 24 months of follow-up, the decision to extract a tooth was taken by a consensus of 3 periodontists of the study group. Of the 1,214 enrolled patients, 306 were examined, 112 were included and 59 remained in the study for two years. Of these, 18 (31%) quit smoking and 41 (69%) continued to smoke or oscillated. The mean number of tooth lost was 0.63 (±1.4). After adjusting for the extractions performed during the treatment phase, the mean number decreased to 0.42 (±1.2), being 0.39 ± 0.8 in the quitters group and 0.44 ± 1.3 in the group the continued to smoke (p=0.88). Even though the cumulative extent and mean number of missing teeth were similar in both groups during follow-up, there was a tendency for a higher tooth loss in the smokers group in the first year of follow-up. It was concluded that smoking cessation did not promote an additional benefit on tooth loss in smokers 24 months after smoking cessation.
