Second Mesiobuccal Canal

Background and Objectives: The success of root canal therapy is depending on cleaning and shaping of the root canals. The root canals have complex morphology and wide individual variations. The purpose of this study was to investigate the prevalence of second mesiobuccal canal (MB2) of maxillary first molars in Erbil population using cone beam computed tomography (CBCT). Materials and Methods: A total of 101 permanent maxillary first molars were randomly se-lected from Erbil citizens. All teeth were examined for the number of root canals and the pres-ence of second mesiobuccal canal by Cone Beam Computed Tomography (CBCT). Result: The MB2 canal was found in 80.2% (the 95% CI is 72.3% to 87.1%) of the analyzed cas-es (81/101). Conclusion: The second mesiobuccal canal was found in a high percentage of the samples. And it is within normal magnitude in comparison with the common findings in the literature. These results indicate that CBCT is an effective, high-precision diagnostic tool for detecting canals.

Descriptive Survey

It is important to understand pulp canal configuration to have a successful endodontic treatment. Cone Beam Computed Tomography (CBCT) radiography is able to assess the pulp canal configuration, especially on the lingual/palatal, compared to the periapical radiography. The objective of the research is to know the prevalence pulp canal configuration of mandibular molar teeth in Indonesia subpopulation Mongoloid race using CBCT radiography. This research is a descriptive survey with a cross-sectional approach, using 38 CBCT radiographs from the patients undergoing dental treatments in hospitals in Medan. The subjects were selected based on research criteria; then their CBCT radiographs were interpreted and analyzed. The result shows the existence of mandibular mesial root type 2-1 (28.94%), 1-2-1 (5.26%), 2-2 (55.26%), 2-1-2-1 (2.64%), 3-2 (5.26%), 3-1 (2.64%), distal root type 1-1 (36.84%), 2-1 (23.68%), 1-2-1 (15.79%), 1-2 (2.63%), 2-2 (13.17%), 2-1-2-1 (5.26%), 1-3-1 (2.63%). The distolingual root of mandibular first molars consisted of type 1-1 (100%).  Mesial root of mandibular second molars of type 1-1 (2.63%), 2-1 (50%), 1-2-1 (5.26%), 2-2 (36.85%), 2-1-2-1 (2.63%), 1-2-1-2 (2.63%), distal root type 1-1 (57.89%), 2-1 (15.79%), 1-2-1 (13.16%), 2-2 (10.53%), 2-1-2 (2.63%). This variation of the pulp canal can be influenced by the shape of roots. A flat root usually contains pulp canal configuration type II – VIII Vertucci, similarly to mandibular molar mesial canals. As a summary, there is a variation of pulp canal configuration in mandibular first and second molars on Indonesian Mongoloid race, as seen from the CBCT radiographs.

Abstract Background: This study aimed to assess the buccolingual inclination of canine and first and second molar teeth and the curve of Wilson in different sagittal skeletal patterns in untreated adults using cone-beam computed tomography (CBCT). Methods: Sixty-six CBCT scans of adults (mean age: 28.74±5.25 years) were evaluated in this cross-sectional study. The images were standardized using the Frankfurt horizontal plane and the interorbital line. The sagittal skeletal pattern was determined using the ANB angle and Wits appraisal. Inclination angles were measured by NNT Viewer and Mimics software. The curve of Wilson was measured by connecting the tips of mesiobuccal and mesiolingual cusps of maxillary first and second molars along the buccal groove and measuring the formed angle. Data were analyzed using ANOVA. Results: The intraobserver agreement was 0.969. The mean inclination of maxillary first and second molars in class I and III patients was significantly higher than that in class II patients (P<0.05). The mean inclination of mandibular first and second molars in class II patients was significantly higher than that in class I and III patients (P<0.05). The difference in inclination of maxillary and mandibular canine teeth was not significant (P>0.05). The mean curve of Wilson in second molars of class II patients was significantly higher than that in class I patients (P<0.05). Conclusion: In different sagittal skeletal patterns, a compensatory relationship exists between the opposing teeth, which along with the standards of crowns, can be used to determine the appropriate position of teeth in dental arch.

Aim: The aim of this study was to demonstrate the anatomical structure of pulp chamber, measure the volume of the total pulp chambers in mm3 and evaluate the pulp chamber volume changes by age and gender statistically in mandibular and maxillary first molars by means of CBCT. Methodology: In our study, CBCT examinations of patients between the ages of 7-18 years, which were carried out due to different reasons were evaluated retrospectively. The CBCT images of healthy total of 160 lower and upper right permanent first molar teeth were selected randomly and the volumes of the total pulp chamber were measured in mm3 with the 3D Slicer software program. We analyzed the collected data with statistical analysis methods and we evaluated whether there was any difference between the patients grouped according to the age in respect of volume changes in the total pulp chamber and whether there was any difference between the mean volume values and gender of the patients within the same group. Results: Comparison of the volume measurements of the lower and upper first permanent molar teeth between the groups showed that the volume values of the total pulp chamber decreased depending on the age (p<0.05). Regarding gender, volume decrease related to age was statistically more significant among females. We determined in all age groups except age 7-9 group that the volume value of the total pulp chamber of the upper permanent first molar teeth was statistically higher than the volume value of the total pulp chamber of the lower permanent first molar teeth (p<0,05). Conclusion: We believe that CBCT is an easy and conservative method for the 3D-imaging of the pulp chamber, volume measurement and examination of the dimensional changes of the total pulp chamber depending on deposition of secondary dentin.   How to cite this article: Açıklar Kavas A, Tümen EC.

ABSTRACT Aim Use of dental implants in edentulous patients has become a common treatment modality. Treatment of such implants requires radiographic evaluation, and in most cases several different imaging techniques are necessary in order to evaluate the height, width and the structure of bone at implant site. The aim of this study was to evaluate the influence of head orientation in linear measurement for implant planning in cone beam computed tomography (CBCT). Materials and methods In the present in vitro study, 11 human dry mandibles were used. The width and height of bone at the central, canine and molar teeth areas were measured on the left and right sides by using digital calipers (as gold standard) and on CBCT images with Reaxis option and no Reaxis. Data were analyzed with Statistical package for the social sciences (SPSS) 18, using pair t-test, Tukey test and intraclass correlation (ICC). Results Data were collected by evaluation of 11 skulls and 66 samples on the whole. There were no significant differences in bone width in any area in both Reaxis and no Reaxis option (p > 0.05). There were significant differences in bone height in the central (p = 0.005) and molar teeth areas (p = 0.010). The results did not show any significant differences between the observers (p = 0.329). Conclusion Using the Reaxis option does not affect the measurement of bone width, while use of this option can make a significant difference for height measurements.

Objectives: This study aimed to measure the buccal cortical plate thickness in the mandible of dentate adults in an Iranian population using cone-beam computed tomography (CBCT). Materials and Methods: Eighty CBCT images were evaluated in this study using NNT Viewer 6.0 software. Images had high-resolution and had been taken by NewTom CBCT scanner with 11 x 8cm field of view. Measurements were made using the digital ruler of the software with 0.1mm accuracy. All analyses were performed by two observers: an oral and maxillofacial radiologist and a general dentist. In case of disagreement between the observers, measurements were repeated and the mean value was used for analysis. Data were analyzed by using linear regression. Results: The results showed that the thickness of buccal cortical plate increased from the canine towards the second molar site. The second molar site had the greatest density and thickness. Gender had a significant effect on the thickness of buccal cortical plate (P<0.05) but the effect of right/ left quadrant was not significant (P>0.05). The effect of age on this thickness was insignificant in some (P>0.05) and significant (P<0.05) in some other areas such that by an increase in age of patients, this thickness decreased (i.e. at the apex of canine, second premolar and second molar teeth). Conclusion: The buccal cortical plate thickness of the mandible increases from the anterior towards the posterior region, and the second molar area has the greatest thickness and density suitable for placement of orthodontic mini-implants or harvesting autogenous grafts.
