Aim: The aim of the study was to examine the prevalence of maxillary sinus septa (MSS) 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 MSS 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 MSS with significance set at 5%.  Results: MSSs were observed in 201 out of 700 sides (28.71%) and 141 out of 350 patients (40.28%), of which, 70 were in males and 71 in females. MSS were also observed in a higher prevalence on the bilateral side. (17.14%). Female patients showed higher prevalence (41.27%) than the male patients (39.32%). Conclusion: MSS was observed in 40.28% of examined Turkish subjects and detected more frequently in females and on the bilateral side.   How to cite this article: Laçin N, İzol BS.

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.

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.

The Relationship

Purpose: The aim of this study was to evaluate the prevalence of antral pseudocysts(AP), maxillary sinus septas(MSS) and the relationship between AP and MSS by using cone-beam computed tomography(CBCT).Methodology: The CBCT scans of 466 patients (237 male, 229 female ranging in age between 13 and 83) were included in our study. The presence or absence of AP and MSS were confirmed at axial, sagittal, and coronal sections of CBCT images by considering gender and localization. For statistical analysis, Pearson chi-square and Spearman correlation tests were used.Results: One hundred-ninety eight out of 466 (42.49%) patients had AP in the right and left maxillary sinus. There was a significant difference in the prevalence of AP between men and women (p≤0.001). The prevalence of AP was higher in men than in women. Twenty-eight out of 237 patients in men(11.81%) and 35 out of 229 patients in women(15.28%) had MSS in the right and left maxillary sinus. Conclusion: The prevalence of AP and MSS was 42.49% and 13.52%, respectively and the prevalence of MSS was lower in our study than other studies. We did not determine the relationship between AP and MSS in the maxillary sinuses.   How to cite this article: Yalçın M, Laçin N.

ABSTRACT Objective: The aim of this study was to determine the root and canal morphology of the maxillary and mandibular anterior teeth in a Turkish population by analyzing cone-beam computed tomography (CBCT) images. Materials and Methods: CBCT images of 417 females and 410 males with a mean age of ranging from 14 to 70 years were examined in this study. A total of 1453 maxillary central incisors, 1504 maxillary lateral incisors, 1523 maxillary canines, 1582 mandibular central incisors, 1603 mandibular lateral incisors, and 1604 mandibular canines were analyzed. The number of root canals and the canal configurations were investigated and then were classified according to Vertucci's classification. The data were analyzed with the Pearson Chi-square test. Results: The Type 1 canal configuration was most prevalent in the maxillary anterior teeth (96.8-99.7%). The Types 2, 3, 4, and 5 canal configurations were observed within the range of 0-1.3%, 0-0.8%, 0-0.7%, and 0-1.8%, respectively. In the mandibular anterior teeth, the Type 1 canal configuration was most prevalent (77-95%). The Types 2, 3, 4, and 5 canal configurations were observed within a range of 0.2-2.7%, 0.2-1.6%, 0.9-5.9%, and 1.8-14.4%, respectively. The prevalence of two canals was higher in males than in females both in the maxillary and mandibular anterior teeth (P < 0.05). Conclusions: Type 1 was the most prevalent canal configuration of maxillary and mandibular anterior teeth in the Turkish population. Type 5 was the most frequently observed canal configuration of the two canalled teeth. The incidence of root canal numbers and configurations differed with sex.

Periapical Radiography

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.

Introduction:To evaluate cone-beam computed tomography (CBCT) images in order to determine the presence of mandibular second molars with C-shaped canal system and classify them.Methods:3035 CBCT images fulfilling the selection criteria were observed. Once established the presence of C-shaped canal system, they were classified according to the anatomic and radiographic classification of Fan et al. Data description was made by frequencies and percentages rates, with a 95% confidence interval (IC95) according to score method. Comparisons were assessed by means of the Chi-square test with a significance level equal to 5%.Results:Of the 225 selected patients, 44 exhibited C-shaped canals (20%; IC95: 15% to 25%). 70% (IC95: 56% to 82%) of patients showed a bilateral C-shaped canal system pattern. Regarding to the axial plane -anatomic classification-, there was a significant association between the root third and the configuration (Chi-square=76.89; p<0.05): at the coronal third prevailed the C1 configuration (47%; IC95: 36% to 58%); at the middle third prevailed the C3d configuration (39%; IC95: 28% to 50%) and at the apical third, the C4 configuration (35%; IC95: 25% to 46%).
