Background. Knowing the radiologic anatomy of the mandibular canal is essential to perform optimal anesthetic techniques in dentistry, especially in endodontic and surgical procedures. Bifid mandibular canals figure as anatomic variations that may hamper dental anesthesia and lead to surgical accidents.Objective. This study aims to investigate the prevalence of bifid mandibular canals in cone beam computed tomography (CBCT) images of patients under dental treatment.Material and methods. The sample consisted of 700 patients (448 females and 252 males) under dental treatment. CBCT images taken from each patient for dental treatment purposes were analyzed retrospectively in order to search for bifid mandibular canals. The detected bifid mandibular canals were classified according to their morphological arrangement and the prevalence of this anatomic variation was tested for association with patients’ sex using Pearson’s Chi-square test (2).Results. The prevalence rate of bifid mandibular canals reached 2% (n=14). Mandibular canals with an additional bifurcation towards the anterior region of the mandibular ramus were the most prevalent (100%). Lack of statistical association was observed between the occurrence of bifid mandibular canals and patients’ sex ( p >0.05).Conclusion. Despite uncommon, bifid mandibular canals may occur. Dentists must be aware of this anatomic variation to perform safely and optimally in the clinical routine.

Aim: The aim of the study was to examine the prevalence of bifid mandibular canals (BMC) in a Turkish population, using cone-beam computed tomography (CBCT). Methodology: The CBCT images of 350 untreated patients (178 male, 172 female ranging in age between 18 and 65,) were included in this study. The presence or absence of BMC was determined in axial, sagittal, and coronal planes by considering gender and side. For statistical evaluation, a chi‑square test was used to determine any differences in the prevalence of BMC with significance set at 5%. Results: BMCs were observed in 129 out of 700 sides (18.42%) and 97 out of 350 patients (27.71%), of which, 55 were in males and 42 in females. Regardless of gender, the right side was more frequently affected (73%). Male patients showed higher prevalence (15.71%) than the female patients (12%). Conclusion: BMC was observed in 27.71% of examined Turkish subjects and detected more frequently in males and on the right side.

The determination of the success of endodontic treatment has been often discussed based on outcome obtained by periapical radiography. The aim of this study was to verify the influence of intracanal post on apical periodontitis detected by cone-beam computed tomography (CBCT). A consecutive sample of 1020 images (periapical radiographs and CBCT scans) taken from 619 patients (245 men; mean age, 50.1 years) between February 2008 and September 2009 were used in this study. Presence and intracanal post length (short, medium and long) were associated with apical periodontitis (AP). Chi-square test was used for statistical analyses. Significance level was set at p<0.01. The kappa value was used to assess examiner variability. From a total of 591 intracanal posts, AP was observed in 15.06%, 18.78% and 7.95% using periapical radiographs, into the different lengths, short, medium and long, respectively (p=0.466). Considering the same posts length it was verified AP in 24.20%, 26.40% and 11.84% observed by CBCT scans, respectively (p=0.154). From a total of 1,020 teeth used in this study, AP was detected in 397 (38.92%) by periapical radiography and in 614 (60.19%) by CBCT scans (p<0.001). The distribution of intracanal posts in different dental groups showed higher prevalence in maxillary anterior teeth (54.79%). Intracanal posts lengths did not influenced AP. AP was detected more frequently when CBCT method was used.

Aim: The aim of this study is to characterize the anatomical findings of the MLF in a Turkish population, using cone-beam computed tomography (CBCT). Methodology: The CBCT images of 350 untreated patients (164 male, 186 female ranging in age between 18 and 65) were included in this study. The distribution of MLFs were determined in axial, sagittal, and coronal planes by considering gender and side. For statistical evaluation, a chi-square test was used to analyze independent samples. P<0.05 was considered statistically significant. Results: At least 1 canal was observed in all subjects (n = 350). The most common result was a single canal. Among the 164 male patients (46.86%), 98 had 1 canal (59.75%); 59 had 2 canals (35.97%); and 7 had 3 canals (4.26%). Among the 186 female patients (53.14%), 134 (72.04%) had 1 conduit or canal; 49 (26.34%) had 2 canals; and only 3 case (1.61%) presented with 3 canals. Difference between genders was statistically significant. Conclusions: Vascular canals and anastomoses presence in anterior mandible which are sufficient for severe hemorrhage complications. The distribution of MLFs must be taken into account during presurgical planning.

AIM: The purpose of the study was to measure and compare the prevalence of mandibular canal (MC) location variations in regard to mandibular first molars in both genders at different age groups. METHODS: A retrospective study was performed on 80 cone-beam computed tomography scans. Distance between MC and apical apices of first molars, buccal and lingual cortical plates was measured in both sides. RESULTS: 80 scans with 160 sides were analyzed. Distances was measured bilaterally for all scans with mean (5.22 ± 0.77) in men versus (4.1 ± 0.7) in women at group age 31–40 apical to apices of first molars. The mean was (3.77 ± 0.62) in men versus (2.81 ± 0.47) in women at same age group at buccal side, lingually the mean was (4.02 ± 0.67) in men versus (3.67 ± 0.26) in women in the same age group. CONCLUSION: Our study showed that there were decrease in measurements in older age group in both genders and in female groups more than male groups but with no statistical significant difference.

ABSTRACT The probability of morphologic variations in a tooth should never be misconstrued and the cognition of these variations is the cue to successful endodontic treatment. The form, configuration, and number of root canals in maxillary first molar have been studied for more than half a century. An anatomic variation like three canals in the distal root of maxillary first molar is not frequently reported. Apart from a properly designed access cavity, well-angulated radiographs, and routine use of loupes, the practitioner should consider using cone beam computed tomography as an auxiliary method for detecting complex root canal anatomy. This clinical case report presents the successful management of maxillary first molar with six root canals with the use of computed tomography scans as a diagnostic aid. Key Messages The incidence of second distobuccal canal ranges from 1.64 to 9.5%. However, the incidence of third distal canal (distopalatal) is rare (<1%). This report highlights the importance of computed tomography in the successful diagnosis and management of maxillary first molar.

Pulp Stones

The aim of this study was to evaluate the prevalence and distribution of pulp stones in a group of Peruvian adults using cone beam tomography (CBCT). Materials and methods: 60 randomly selected CBCT from a tomographic center in Lima, Peru were analyzed. A total of 1263 images of teeth using the Point 3D Combi 500 S tomograph were evaluated. Images analysis was performed with Real Scan software and all teeth were evaluated in sagittal, axial and coronal views. All measurements were subjected to a chi square test. (p<0.05). Results: Of the 1263 teeth, 30.8% presented pulp calcifications through the CBCT. The prevalence of calcifications was higher in women than in men. The maxillary and mandibular molars were the groups of teeth with the highest frequency of pulp stones. There was significance between the pulp stones and the gender, age range, type and state of the tooth. Conclusions: The maxillary first molars had a higher prevalence of pulp calcifications than the mandibular ones. The presence of caries increased the possibility of the appearance of these calcifications, specifically in the maxillary teeth. CBCT could be a sensitive tool to detect pulp stones. Knowledge of the distribution of pulp stones can help dentists in the clinical treatment of endodontics.
