Introduction: Maxillary molars usually have three roots, four canals and the extra canal often exists in the mesiobuccal root. This study aimed to investigate the root morphology of maxillary first and second molars using CBCT. Materials & Methods: In this descriptive-analytical study, CBCT samples of 200 patients referred to maxillofacial radiology centers were selected and evaluated. Two-dimensional images in panoramic, cross-sectional, and transverse axial planes and three-dimensional images of the maxilla building that were reconstructed by a computer were examined. Analyzed data using one-way ANOVA and t-test (p value < 0.05) Results: The highest number of roots in the first molar was 3 (89.5%) and, the highest number of the second molar was 3 (90%). The maximum number of root canals in the first molar was 4 (65%) and, the highest number of root canals in the second molar was 3 (68%). The MB2 canal of maxillary first molars was 67.5% and the MB2 canal of maxillary second molars was absent at 71.5%. The presence of MB2 canal of maxillary first and second molars had no significant difference (p value > 0.05), but the presence of MB2 canal of maxillary first and second molars was significant (p value < 0.001). Conclusion: There is a significant relationship between being unilateral and bilateral with the presence of the mesiobuccal canal. Most of the first maxillary molars and, maxillary second molars had three separate roots. Also, there was no significant relationship between gender and side of study with the presence of mesiobuccal canal.

Introduction: The objective of the study was to make the comparison of the root canal length of different types of teeth in black-Africans (Bantu) to that of Caucasians and Asians. Materials and Methods: Data from a prospective cross-sectional study of Bantu (Black Africans) subjects aged from 18 to 45 years who were admitted in Service of Conservative Dentistry of Kinshasa University, root canal length were compared with already published data from studies involving Caucasians and Asians. Results: This study includes 720 subjects; 480 (66%) were female and 240 (34%) were male. A total of 818 teeth were examined with 1539 root canals. The upper central incisor and the lower first molar predominated respectively in the maxilla and the mandible regions. There is a significant difference between the canal length of Bantu and Asians in the palatal canal of the upper second molar by 3.1 mm (p= 0.00). Eight different canals of Bantu were longer as compared to a single canal for Asians (p <0.05). This include the Vestibular (V) and palatine (P) canals of Bantu the first premolar (PM1 ), palatal of the second premolar (PM2 ), mesio-vestibular (MV), disto-vestibular (DV) and palatine (P) of the first molar (M1 ) mesio-vestibular and palatal of the second molar (M2 ). The lateral incisors (IL) (p= 0,01) and the canines (p= 0.12) of the Asians were longer than that of the Bantu. The Caucasians presented with longer canines than Bantu with a length difference of 1.7 mm (p= 0.11). Four Caucasians also presented with longer canals of the Mesio-Vestibular (MV) and mesiolingual (ML) of the two molars (M1 and M2 ) as compared to one for Bantu are the longest (p <0.05). Exceptionally, the distal canal (D) of the second molar (M2 ) of the Bantu was longer than that of the Caucasians, with a length difference of 1.5 mm. Conclusion: The root canal length of Bantu is between than those of the most Asian and shortest Caucasian.

The objective of this study was to analyse the effectiveness of some parameters which characterise the change in morphology in human root canals subjected to ProTaper rotary enlargement with the help of an X-ray microfocus computed tomography (MCT) and to introduce a novel parameter that is effective in quantifying changes in root canal morphology. Ten each straight and curved root canals with mature apices chosen from extracted human upper incisor and canine teeth were scanned with MCT before and after canal shaping using ProTaper rotary instruments in order to facilitate three-dimensional digital reconstruction and quantitative gauging of relevant instrumental parameters and changes therein (surface area and volume). Root canal geometry change and the effectiveness of shaping were quantified with Structure Model Index change (ΔSMI) and surface area change to volume change ratio (ΔSA/ΔV). These two parameters were also tested on simulated canals. Postinstrumentation cross-sectional changes were also analysed, but only on the plastic blocks. Statistical analysis of parameters was carried out to verify the significance of results. Analysis of cross-sectional shape of postinstrumented resin simulated canals showed statistically significant decrease in Form Factor (p<0.05) and statistically significant increase in Eccentricity (p<0.005). ΔSMI did not show significant difference between straight and curved canals. SMI values showed bidirectional change during root enlargement which questions the reliability of this metric in analysing instrumentation. Statistically significant (p<0.005) deviations in ΔSA/ΔV were quantified as 1.92 and 3.22 for straight and curved human canals, respectively. Instrumentation-induced canal geometry change was determined to be more pronounced in curved canals using the novel parameter ΔSA/ΔV. This has been proven as being a statistically accurate and reproducible parameter for quantitative characterisation of root canal geometry change and differentiation of preparational efficacy for both straight and curved root canals.

BACKGROUND: Safety climate is a common insight of staff that indicates individuals’ attitudes toward safety and priority of safety at work. OBJECTIVES: Nursing is a risky job where paying attention to safety is crucial. The assessment of the safety climate is one of the methods to measure the safety conditions in this occupation. The aim of this study was to assess the safety climate of rehabilitation nurses working in hospitals in Tehran. METHODS: This is a cross-sectional study which was carried out on 140 rehabilitation nurses selected from all hospitals and clinics in Tehran in 2019. To collect the required data, a two-section questionnaire was used. The first section was related to demographic factors and the second part (22 statements) was to measure the safety climate using nurses’ safety climate assessment questionnaire. The collected data were analyzed by SPSS V16 using independent t-test, ANOVA, Kruskal-Wallis and Mann-Whitney U test at the 5% level. RESULTS: Findings showed that the total mean of safety climate was 3.06±0.56. According to the results, a significant difference was found between the positive and negative satisfaction of nurses with safety climates (P-value = 0.03), communication with nurses (P-value = 0.01) and supervisors’ attitude (P-value = 0.02). Furthermore, a significant difference in safety climate between the individual with the second job and the individual without second could be observed (P-value = 0.01). CONCLUSIONS: The results indicated that the safety climate was not at an acceptable level. Thus, it is essential to introduce safety training courses (e.g. safety, work-rest balance, and so on) and to improve the safety performance at work.

Objectives: To assess the concepts of complete denture occlusion among dental fraternity. Study Design And Setting: Cross-sectional study conducted at various dental hospitals and institutes of Karachi, for a period of six months, from 1st June’2019 to 30th November’2019 Methodology: Total 849 dental practitioners who are currently practising were included. A well-structured and validated questionnaire was used for data collection. SPSS version 25 was used. Results: Bilateral balanced occlusion was an ideal occlusion by majority subjects i.e, 530(62.4%) in patients with wellformed ridges, followed by 464(54.7%) candidates with skeletal class 1, total 376(44.3%) chose it with uncontrolled diabetes mellitus, 365(43%) in single complete denture cases, 339(39.9%) with increased inter-arch space, 298(35.1%) with parafunction habits, 296(34.9%) in patients with history of neuromuscular disorder and 271(31.9%) where a complete denture opposes a removable partial denture. Furthermore, Lingualized occlusion was preferred by 341(40.25%) participants for patients with skeletal class 3. Total 316(37.2%) candidates chose it for patients with displaceable supporting tissue followed by 264(31.1%) who chose it for skeletal 2 and 260(30.6%) for cases of highly resorbed ridges. Lastly, 311(36.6%) chose canine guided occlusion with highly resorbed ridges accompanied by high aesthetic demand A significant difference between education level and knowledge of occlusal schemes was also found. Chi-square (73.87), df 6, p-value =0.000. Conclusion: Dental practitioners lack adequate knowledge of occlusal schemes in terms of prescription in complete denture patients. A significant difference between the education level and knowledge of occlusal schemes was found. Therefore, awareness of various occlusal schemes should be increased at undergraduate level.
