Root And Canal Morphology Of Mandibular Second Molars In An Egyptian Subpopulation: A Cone-Beam Computed Tomography Study, Shehabeldin Mohamed Saber Prof.Dr.

Dentistry

Background: This study was using Cone beam computed tomography (CBCT) to examine the anatomical variations in mandibular second molars in an Egyptian sub-population. Methods: A total of 350 CBCT images (215 females and 135 males, aged 15–65 years) of mandibular second molars were evaluated. Samples were evaluated in terms of: number of roots, number of root canals, roots’ cross section as well as prevalence and configurations of C-shaped canals. Statistical analysis was done to highlight differences between different categories and their prevalence among genders (significance level was set at p < 0.05). Data were presented as frequency and percentage values and were analyzed using chi square test followed by pairwise comparisons utilizing multiple Fisher’s exact tests with Bonferroni correction. The significance level was set at p < 0.05 within all tests. Results: Of the 350 mandibular second molars evaluated, 87.2% were non-C-shaped while 12.8% were C-shaped with no gender-based statistically significant differences (χ2 = 0.19, p = 0.656). Most samples had three root canals (80%) followed by two (16%), then one (3.2%), and finally four (0.8%) root canals. Among the non-C-shaped molars, presence of two roots was most common (83.4%) followed by presence of a single root (16.2%), and only one sample (0.2%) had three roots, and this had no correlation with gender (χ2 = 1.86, p = 0.431). In the mesial roots Type IV Vertucci was the most common configuration found (68.8%), while Type I was the most prevalent in the distal roots (91.8%). The long oval configuration was the most commonly found cross section in mesial roots while “oval” was the most prevalent in distal roots. Conclusion: Egyptian sub-population shows highly variable morphological features in mandibular second molars, hence, CBCT is highly recommended on case-to-case conditions.

International Arab Journal of Dentistry

Objective: the assessment of distal cantilever length in implant supported infrastructure by comparing the load to fracture in two different framework esthetic materials (Zirconia and Polyetheretherketone (PEEK)) with two different cantilevers loading distances (10mm, 15mm). Material and methods: 20 frameworks were fabricated and divided into 4 groups (n=5): according to the material type Peek, zirconia, and according to the cantilever loading distance (10), or (15) mm and a load-to-fracture test was used until complete fracture of specimens occurs. Results: The effect of material type and cantilever loading distance were statistically significant for the mean load-to-fracture values (P< 0.05). The Zirconia group failed at higher fracture loads (817 N) than the Peek one (651 N). Frameworks with 10 mm cantilever loading distance failed at higher fracture loads than specimens with 15 mm. Conclusion: Peek is a suitable material for all-on-four framework reconstruction in specific situations, and there is a higher success rate when the distal cantilever length is kept at minimal value (10mm).

Management Of Pulpal Floor Perforation Using Biodentinetm : Case Report, Chaima Bouhajja, Mayada Jemâa, Mohamed Bassem Khattech

International Arab Journal of Dentistry

During endodontic treatment in multi-rooted teeth, furcation perforation refers to an opening in the pulpal floor, leading to a communication with the periodontal ligament space. A three-dimensional hermetic seal, with a biocompatible material, is a key point for the success of pulp floor perforation repair. MTA® has been considered, for a long time, as a gold standard in furcation perforation repair. Besides, BiodentineTM, when used for the same purpose, showed considerable performance and good results. The purpose of this paper was to report the management of an iatrogenic perforation of pulpal floor in the maxillary right first molar, using BiodentineTM.

Molar Macrowear As A Proxy For Age In A Captive Sample Of Papio Hamadryas, Lauren Conrad

Biological Sciences Undergraduate Honors Theses

This study is methods-focused, centering around molar crown macrowear and its performance as a proxy for age in a sample of pedigreed, non-human primates. It analyzes the correlation between age-structured variables and molar wear among both males and females in a captive group of baboons. Here, I examined whether wear is significantly correlated with age-related variables (i.e., generations/cohorts) and whether the structure of the “age” dataset differed across wear categories. Because chronological age is unknown, I used documented pedigrees and parent-offspring relationships to group individuals into possible generations. I then used dental development charts to group individuals into cohorts based …

Treatment Of Gingival Fenestration Using Mucoperiosteal Flap With Connective Tissue Graft: A Report Of Two Cases, Swati Jaglan, Shikha Tewari

Journal of Dentistry Indonesia

Fenestration term is derived from the Latin word ‘fenestra’ means ‘window’. Gingival fenestration is not found in routine while its actual occurrence is assumed to be higher. Additionally, if these mucogingival defects persist for a longer duration it may lead to adverse outcomes like compromised esthetics, hypersensitivity, plaque and calculus deposition, and susceptibility to dental caries. Present cases of gingival fenestration were successfully treated by using full-thickness flap elevation with connective tissue graft placement. Two cases were presented with the accumulation of plaque and calculus and having gingival fenestration to the respective sites. After phase 1 therapy, full thickness flap …
