The goal of this in vitro study is to compare the marginal fit and internal adaptation of all-metal crowns in polished crown preparations and non-polished crown preparations The main question it aims to answer is: are the non polished tooth preparations comparable to polished preparations? We will compare polish and non polish groups and see their effects on marginal fit and internal adaptation of all metal crown

OBJECTIVEThis study aimed to investigate the correlation between genetic factors and the occurrence and progression of temporomandibular disorders (TMDs) using a comprehensive review and meta-analysis.DESIGNA comprehensive search was conducted using the ScienceDirect, PubMed, Cochrane Library, Dimensions, and Emerald databases. A reviewer selected the study using modified PICO criteria, considering human subjects with TMDs, comparing different genetic factors among TMD and non-TMD patients, and reporting TMD signs and symptoms as outcomes. The methodological standards of the eligible papers were assessed using the Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Non-randomized Experimental Investigations. Information was collected methodically and examined.RESULTSThe electronic database search yielded 851 articles, 19 of which were included in this study. The data analysis showed a significant influence of genetic factors, such as polymorphisms and gene differences, on the development of TMD signs and symptoms, such as myofascial pain, chronic pain, and disc displacement. In addition, gene polymorphism significantly influenced TMD development, with an odds ratio of 2.46 (1.93-3.14) and p of 0.00001.CONCLUSIONSGenetic factors significantly influenced TMD signs and symptoms, and genetic polymorphisms significantly influenced TMD onset and progression. Further research should be conducted in diverse settings with larger sample sizes to verify and validate these findings.

ObjectiveTo determine characteristics and motivational factors of applicants applying for MHPE program at a Public-sector University, Karachi.MethodsThis cross-sectional descriptive study, conducted from September till October 2022, included all 60 applicants of MHPE program at Jinnah Sindh Medical University. The survey questionnaire was administered (google form) and comprised questions seeking demographic information, few questions with options to select and 34 statements to be responded on 5-point scale. One open-ended question asking motivational factor/s. Data was analyzed using SPSS and independent sample t-test was used to determine the differences between groups of applicants based on demographic factors.Results48 participants responded, mean age was 35.8 ± 7.3 years, with predominantly males (81.3%), graduates of medical and dental programs (n = 29), and employed in medical education departments (n = 36). Most of the applicants wanted to join the program to improve their teaching skills, especially psychomotor skills teaching (96%) and educational research [90%]. Majority (64.6%) learned about the program through peers, whereas 29.9% independently chose to pursue the program. Their primary motivation stemmed from their inability to secure admission elsewhere and the belief that minimal effort was needed to acquire the degree (mean score 4.58 ± 0.87 and 4.42 ± 0.94), respectively. For medical and dental graduates, comparable responses emerged, displaying a statistically significant correlation (p < 0.05). However, there was mutual disagreement regarding the program's structure and faculty as motivating factors.ConclusionPrimary motivations to earn an MHPE degree were to improve teaching skills. Motivations to apply to this particular program was the failure to be accepted elsewhere and the perception that minimal efforts were needed to complete this program. The program goals and purpose need to be better propagated along with changes in the admission processes in order to encourage those individuals to apply who are motivated to pursue medical education as a career.

A Surface Topographical Analysis of Lithium Disilicate Ceramics Pretreated With Rose Bengal, Er:YAG Laser, and Ceramic Primer on Bond Integrity, Surface Roughness, and Bond Failure to Composite Resin

To evaluate adhesive bond integrity and surface roughness (Ra) of LDS ceramics following various surface modification treatments. Forty LDS ceramic disks were manufactured and allocated into distinct groups according to the pretreatment procedure. Group 1 samples were treated with HF (hydrofluoric acid) and S (silane). Group 2 uses RBe (Rose Bengal photosensitizer) S. Group 3 utilizes SECP (self-etch ceramic primer), while Group 4 employs Er:YAG laser. The Ra, shear bond strength (SBS), and surface topography of the conditioned LDS ceramic were evaluated. The bonding of all LDS ceramics was assessed with a universal testing machine. Debonded samples were analyzed using a stereomicroscope. The Ra and bond integrity values were assessed through the utilization of a two-way ANOVA, followed by Tukey post hoc testing. The samples prepared with HF+S displayed the highest Ra and bond values. However, group 2 (RBe+S) exhibited the least bond strength. There were no notable disparities in the results regarding the strength of the bonds among group 1, group 3 (SECP), and group 4 (Er:YAG laser+S). Er:YAG and SECP show promise as potential substitutes for hydrofluoric acid (HFA) in conditioning LDS ceramics, yielding satisfactory bond scores by positively altering the surface morphology.
