Epidemiological evaluation of apical periodontitis prevalence in an urban Brazilian population

Abstract

The present study aimed to assess the prevalence of apical periodontitis (AP) in an urban Brazilian population according to gender, age group and tooth type. Data were collected from clinical files containing the medical and dental histories and periapical radiographs of 1,126 patients treated at the School of Dentistry at Universidade do Estado do Rio de Janeiro between March 2000 and December 2010. A total of 15,724 periapical radiographs were evaluated. All the radiographs were evaluated by two independent, previously calibrated endodontists (kappa = 0.88). Periapical areas on the radiographs were classified as N (normal) or AR (apical radiolucency). The frequency of AP and the 95% Confidence Interval (95%CI) were calculated according to gender, age group and tooth type. Differences between groups were calculated using the Z-test at a significance level of 5% (p < 0.05). AP was present in 7.87% of the samples, with 16.70% occurring on previously endodontically treated teeth and 44.65% occurring on teeth referred for endodontic treatment (TR-RCT). The frequency of AP was higher among females (64%) than among males (35%). The central and lateral maxillary incisors were the most frequently affected teeth. The frequency of AP was higher among individuals between 30 and 49 years of age. In this population, AP was more prevalent among females and among individuals between 30 and 49 years of age, and the central and lateral maxillary incisors were the most frequently affected teeth.

Prevalence of endodontic diseases: an epidemiological evaluation in a Brazilian subpopulation

“…Therefore, data from endodontic epidemiological surveys may contribute to the improvement of this knowledge 7 . Investigations on the prevalence of pulp and periradicular diseases in the Brazilian population produced few studies [8][9][10][11] and most of them were conducted exclusively based on radiographic assessments for the diagnosis of such infections. Considering the importance of epidemiological investigations, the objective of this study was to determine the prevalence of pulp and periradicular diseases diagnosed in a Brazilian subpopulation, correlating this information to gender, age group and most affected teeth.…”

Frecuencia y características de hallazgos endodónticos en radiografías panorámicas digitales

“…Of the total number of teeth studied, 0.97% in 18.3% of radiographs have an associated apical lesion, figure which tends to decrease with age, unlike other reports where it goes from a 50% prevalence at age 50 to a 62% prevalence at age 60 and over (8) , or in Brazil with a lesion prevalence of 7.87% (9) , which is explained here because patients prefer extraction to retreatment or apical surgery. The presence of apical lesions indicates an increased need for treatment, since it is necessary to redo the endodontic treatment or apical surgery, which may entail an unfavorable prognosis for the tooth treated and increase costs.…”

Perfil dos laudos de exames radiográficos intrabucais realizados no sul catarinense

“…Considerando a análi-se realizada a partir dos laudos radiográfi-cos (n=290), a mediana de idade observada foi de 30 anos (15,0). Em relação ao gênero, a maioria dos pacientes foi do gênero feminino (56,6%; n=164).…”

“…Nesse contexto, um estudo realizado na Universidade do Rio de Janeiro avaliou a prevalência de periapicopatia em uma população urbana brasileira. Os resultados, mostraram predominância de lesões periapicais no gênero feminino, na faixa etária de 30 a 49 anos de idade, o que se diferencia de nossos achados, ou seja, mais lesões encontradas no gênero masculino 15 . A presença de dentes impactados não foi um dos achados mais frequentes na nossa pesquisa.…”
