Quality of Endodontic Treatment and Prevalence of Apical Radiolucencies in a Bulgarian Subpopulation: a CBCT Analysis

Abstract

Introduction: The advent of Cone Beam Computed Tomography (CBCT) in endodontics has enhanced the diagnosis of periapical radiolucencies and the assessment of endodontically treated teeth.  Aim: The purpose of this study was to assess the prevalence of periapical radiolucencies in a Bulgarian subpopulation and the quality of previous endodontic treatment using CBCT scans. Materials and methods: This study included 2795 roots from 160 Large FOV CBCT which were evaluated by two independent examiners using two scoring systems: CBCT-PAI and PESS.  Results: The inter-examiner agreement spanned from strong to almost perfect (0.892 and 0.983). The prevalence of periapical lesions according to the two scoring systems was 23.1% and 12.9 %, respectively. The prevalence of endodontically treated teeth was high (34.1%). Sixty-five percent of them presented with signs of periapical radiolucencies, while only 1.4% of all non-treated roots had a periapical lesion. A significant association between periapical disease, poor quality of the root canal filling and inadequate coronal seal was found (p<0.001).  Conclusions: The prevalence of periapical disease in endodontically-treated teeth in the Bulgarian subpopulation was high. Poor qual-ity of the root canal filling and inadequate coronal seal were assessed as prognostic determinants of treatment failure. CBCT techniques can augment conventional diagnostic techniques in the field of endodontics. 

Prevalência de periodontites apicais e classificação do índice do complexo periapical em brasileiros por meio de tomografia computadorizada de feixe cônico

“…Estudos mostram a prevalência das PA em diferentes amostras e populações ao redor do planeta, como: Iugoslávia (Kamberi et al, 2011), Holanda (Peters et al, 2011), Brasil (Paes da Silva Ramos Fernandes et al, 2013, Coréia (Song et al, 2014), Bélgica (Van der Veken et al, 2017), Finlândia (Huumonen et al, 2017), Sudão (Ahmed et al, 2017), Arábia Saudita (Al-Nazhan et al, 2017, Estônia (Vengerfeldt et al, 2017), Bulgária (Karteva et al, 2021) entre outros. Este trabalho teve como proposição, colaborar com tais estudos, avaliando a prevalência de PA em subpopulação brasileira.…”

Prevalencia de lesiones apicales post endodoncia en tomografías computarizadas de haz conico en una subpoblación peruana

“…Las técnicas de CBCT puede aumentar las técnicas de diagnóstico convencionales en el campo de la endodoncia. (6) En el 2021, Karteva y col. determinaron la prevalencia de lesiones apicales usando del índice CBCT-PAI en la Facultad de Odontología de la Universidad de Plovdiv, fue un estudio retrospectivo, descriptivo y transversal, la muestra fueron tomadas por tomografías computarizadas de haz cónico conformadas por 1843 piezas dentarias, donde se obtuvo una prevalencia del 76.9% para el criterio 1, 14.17% para el criterio 2, un 3.29% para el criterio 3, un 3.94% para el criterio 4 y un 1.15% para el criterio 5, y respecto a las lesiones apicales con tratamientos de conductos fue del 65%. Así se concluyó que la prevalencia de lesiones apicales para este estudio fue alta.…”
