Evaluation of technical quality and periapical health of root-filled teeth by using cone-beam CT

Abstract

Objective This study aimed to assess the quality of root fillings, coronal restorations, complications of all root-filled teeth and their association with apical periodontitis (AP) detected by cone-beam computed tomography (CBCT) images from an adult Turkish subpopulation.Material and Methods The sample for this study consisted of 242 patients (aging from 15 to 72 years) with 522 endodontically treated teeth that were assessed for technical quality of the root canal filling and periapical status of the teeth. Additionally, the apical status of each root-filled tooth was assessed according to the gender, dental arch, tooth type and age classification, undetected canals, instrument fracture, root fracture, apical resorption, apical lesion, furcation lesion and type and quality of the coronal structure. Statistical analysis was performed using percentages and chi-square test.Results The success rate of the root canal treatment was of 54.4%. The success rates of adequate and inadequate root canal treatment were not significantly different (p>0.05). Apical periodontitis was found in 228 (45.6%) teeth treated for root canals. Higher prevalence of AP was found in patients aging from 20 to 29 years [64 (27%) teeth] and in anterior (canines and incisors) teeth [97 (41%) teeth].Conclusions The technical quality of root canal filling performed by dental practitioners in a Turkish subpopulation was consistent with a high prevalence of AP. The probable reasons for this failure are multifactorial, and there may be a need for improved undergraduate education and postgraduate courses to improve the clinical skills of dental practitioners in endodontics.

Prevalence of apical periodontitis and quality of root canal treatment in an adult Saudi population

“…6985). Similar findings were reported by Alfouzan et al,7 and Nur et al42 Comparing restoration with and without AP, males with root canal-treated maxillary incisors with restoration and AP (28.2%) were less common than males treated with restoration without AP (71.8%), p =0.000. Similarly, females with root canal-treated maxillary incisors with restoration and AP (40.2%) were significantly less common than females with root canal-treated teeth with restoration and without AP (56.1%, p =0.042).…”

Evaluation of the diagnostic yield of dental radiography and cone-beam computed tomography for the identification of anatomic landmarks in small to medium-sized brachycephalic dogs

“…In fact, CBCT is already so well established that the latest CBCT-related studies no longer attempt to prove its superiority to conventional radiography, but instead use CBCT-derived images as the criterionreferenced standard for the localization and description of anatomic landmarks or for postoperative quality assessment of endodontic procedures. 18,19,[23][24][25][26][27][28] However, CBCT has not yet reached similar status in veterinary dentistry.…”

Periapical Bone Lesions and Radiographic Features

“…2D radiographs have disadvantages in the detection of periapical lesions due to the superposition of anatomical points (31)(32)(33). Periapical lesions can be correctly detected with cone beam computed tomography (CBCT) by 3D multiplanar images as the superposition of anatomical points is eliminated with this imaging technique.…”
