To 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.
The 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.
The 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.
Our 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.

    • "Successful treatment of endodontic complications is associated with diagnostic imaging techniques that provide information about the teeth and their surrounding structures.[10] These techniques include panoramic,[1112] full-mouth periapical radiograph,[51314] and cone-beam computed tomography (CBCT).[1516] Conventional radiograph images are widely used in endodontic treatment, but they are not very beneficial in the assessment of complex root canal anatomies where anatomic structures may be confused with periapical pathosis.[715] "

    ABSTRACT: Objective: The aim of this retrospective study was to determine the root and canal morphology of the mandibular first and second permanent molars in a Turkish population using cone-beam computed tomography (CBCT). Materials and Methods: CBCT images of mandibular first (n = 966) and second molar (n = 1165) teeth from 850 Turkish patients were evaluated. The root canal configurations were classified according to the method of Vertucci. The data were analyzed by Pearson's Chi-square test. Results: The majority of mandibular molars were two rooted with three canals; however, three roots were identified in 0.05% of the first molars and 0.01% of the second molars, and 100% of the additional root canals were of type I configuration. Mesial roots had more complex canal systems with more than one canal, whereas most distal roots had a type I configuration. Conclusions: Within the limitations of this study, it can be concluded that CBCT scanning provides supplemental information about the root canal configurations of mandibular molars in a Turkish population. This study may help clinicians in the root canal treatment of mandibular molars.

    • "There has been controversy on the influence of coronal restoration in the outcome of root canal treatment and vice versa. Many authors reported that inadequate root fillings would jeopardize coronal restorations [32-35] but Ray & Trope [36] found that the quality of the coronal restoration had a greater impact on the periapical status of root canal treated teeth. This study is limited by the fact that periapical status and coronal restorations were not assessed, hence their relationship to coronal restorations could not be ascertained. "

    ABSTRACT: Background Previous reports indicate that worldwide, the technical quality of root canal fillings is poor. There are few reports from sub-Saharan Africa and none yet from Nigeria where most patients access treatment from non-specialists especially at general dental clinics. The aim of this study was to evaluate the technical quality of root canal fillings done in a general dental clinic with emphasis on the effects of professional experience of the operator, whether tooth was anterior or posterior and whether it was a maxillary or mandibular tooth. Methods Retrospective study of case notes and periapical radiographs of patients with completed root canal fillings seen between 2008 and 2011. Inclusion criteria included cases of primary treatment with available case notes, good quality pre-operative and post-operative periapical radiographs. Technical quality that was assessed was root canal length and homogeneity. Root canal fillings were classified either as Good Quality Endodontic Work (GQEW) or Non- Good Quality Endodontic Work (NGQEW). Results Fifty-one patients aged between 8 and 54 years (mean 28) fulfilled the inclusion criteria for this study. From these, there were 62 root filled teeth giving a ratio of 1.2 root canal filled teeth per person. There were acceptable length of root canal fillings in 71% of teeth, 58.1% were homogeneous while 53.2% were GQEW. There was no statistically significant difference in whether tooth was root filled by junior or senior dentist (p = 0.43), anterior or posterior (p = 0.11). There was significant association between GQEW and maxillary teeth (p = 0.03). Conclusion This study showed that the overall technical quality of root canal fillings done by non-specialists was better than earlier reports but lower than that done by endodontists. Since many patients receive treatment from non-specialists in developing countries, it is necessary to improve technical quality of root canal fillings done in general dental clinics. These could be through improvement in the quality of undergraduate training and more post graduate continuing education courses for skills update.

    ABSTRACT: Abstract Background/Purpose: Eating disorders (EDs) are life-threatening conditions that mainly affect women and can be diagnosed early by dental professionals. The aims of this study were to examine the oral radiographic status of ED patients and compare the performances of dental professionals from different backgrounds in interpreting these findings. Materials and methods: In total, 72 women with EDs and healthy controls matched by age, sex, educational status, and smoking status were included in the project. Standardized full-mouth intraoral periapical radiography with a bisecting-angle technique and digital panoramic imaging were performed in all participants. Five observers independently interpreted the tooth status, the condition of the periapical tissues, and the third molars. Results: Scores for intra- and interobserver consistency were acceptable and were 0.76 and 0.92, respectively. The ED group consumed a larger daily amount of acidic beverages (P < 0.05) than the controls, and a significant positive correlation was observed between the daily acidic-beverage intake and the frequency of vomiting (P < 0.05). In the ED group, the mean number of teeth with untreated carious lesions (P < 0. 01), particularly in the posterior mandibular region (P < 0.05) and periapical pathologies requiring treatment (P < 0.05), were significantly higher compared with healthy individuals. However, the radiographic depth-progression pattern of the carious lesions was similar in the two groups.
