Prevalência e eficácia dos tratamentos endodônticos realizados no Centro Universitário de Lavras, MG - uma análise etiológica e radiográfica

Abstract

The aim of the present research was to conduct an epidemiological evaluation of the endodontic treatment outcomes and their efficacy in teeth presenting periapical lesions based on radiographic analysis. A survey based on the records of the dental clinics at the Lavras University Center, Lavras/MG, between the years 2001 and 2004, has been done. The sample was comprised of 340 patients. Retrospective data regarding gender, etiologic factor involved for endodontic treatment, affected teeth, type of diagnosis, type of pain and treatment were collected. In a second phase, a radiographic evaluation was accomplished in 47 teeth with previous treatment of pulp necrosis with periapical lesion at different followup periods. The success of endodontic treatment was evaluated. The results showed a higher prevalence of women than men among the treated patients (69.4%). The main cause of treatment was dental caries (52.8% for females and 55.8% for males). The most affected teeth were the upper molars (in the female gender) and upper molars and incisors (in the male gender). Teeth presenting necrosis with periapical lesions ocurred in 28.9% for females and 36.5% for males. Most of the teeth did not present pain and the treatment consisted of necropulpectomy II (42.8% for females and 50% for males). There was a high prevalence of partial remission of the lesion in the period between 6 and 12 months (50%). This value increased to total remission in the periods between 12 and 24 months (62.5%), between 24 and 36 months (60%) and after 36 months (83.3%). It was concluded that, pulp alterations and periapical lesions affect men and women indistinctly. The main cause of endodontic treatment was dental caries. The applied technique showed to be effective to treat teeth with periapical lesions.
