Cross-sectional evaluation of the periapical status as related to quality of root canal fillings and coronal restorations in a rural adult male population of Turkey

Abstract

BackgroundTo determine the prevalence of periapical lesions in root canal-treated teeth in a rural, male adult, Turkish population and to investigate the influence of the quality of root canal fillings on prevalence of periapical lesions.MethodsThe sample for this cross-sectional study consisted of 552 adult male patients, 18-32 years of age, presenting consecutively as new patients seeking routine dental care at the Dental Sciences of Gulhane Military Medicine, Ankara. The radiographs of the 1014 root canal-treated teeth were evaluated. The teeth were grouped according to the radiographic quality of the root canal filling and the coronal restoration. The criteria used for the examination were slightly modified from those described by De Moor. Periapical status was assessed by the Periapical Index scores (PAI) proposed by Orstavik.ResultsThe overall success rate of root canal treatment was 32.1%. The success rates of adequately root canal treatment were significantly higher than inadequately root canal treatment, regardless of the quality or presence of the coronal restoration (P < .001). In addition, the success rate of inadequate root canal treatment was also significantly affected by the quality of coronal restorations.ConclusionsOur results revealed a high prevalence of periapical lesions in root canal treatment, which is comparable to that reported in other methodologically compatible studies from diverse geographical locations. In addition, the results from the present study confirm the findings of other studies that found the quality of the root canal treatment to be a key factor for prognosis with or without adequate coronal restoration.

Cross-sectional assessment of the periapical status as related to quality of root canal fillings and coronal restorations in a Yemeni population.

“…In this study, an acceptable standard of treatment was found in 62 roots (9.2%) with 32.3% of them associated with signs of periapical disease. These findings agreed with Gündüz et al 8 , who found that root canal filling was rated as adequate in 425 teeth (41.9%). In the present study, the same group had a 59.8% success rate.…”

Radiographic Evaluation of Root Canal Fillings in a Selected Yemeni Population: A Retrospective Study.

“…There is significant evidence in scientific literature that the technical quality of root canal filling has a substantial effect on the outcome of root canal treatment 1,2 . Failed root canal filling is related to insufficient treatment, through technical error in the canal system of the tooth 3,4 . Numerous epidemiologic studies performed in many countries found a high prevalence of poor technical quality in root canal filling associated with periapical radiolucency [5][6][7][8][9][10] .…”

Relationship between quality of root canal obturation and periapical lesion in elderly patients: a systematic review

“…Therefore, the abstracts of 1097 studies were read. A total of 1022 references were excluded on the basis of their titles and/or abstracts, and 75 were selected for full analysis, but no study could be included in the present systematic review (Fig. ).…”

“…Among the 75 studies selected for full analysis, 27 did not present their results by age groups, which not only made it impossible to calculate percentages of success/failure but also prevented a relationship between obturation quality and periapical health from being determined. This may be explained by the objective of these studies.…”

“…This may be explained by the objective of these studies. The majority of them were seeking the prevalence of AP in a determined site, irrespective of the age of subjects . Other studies used convenience samples or data secundary, such as Chen et al ., who used information from the Northern Manhattan Study, and Zhong et al ., who used data from the Veterans Affairs Dental Longitudinal Study.…”
