Methods: The cross-sectional analytical study was conducted at two public-sector and four privatesector dental colleges in Karachi from June to September, 2018, and comprised students of first to final year of studies. Data was collected using a self-administered questionnaire. Students were asked to mark all reasons that they considered had been an influencing factor on their decision to opt for dentistry. Data was analysed using SPSS 21. Results: Of the 900 forms distributed, 814(90.4%) were collected with complete data; 182(22.4%) males and 632(77.6%) females. The overall mean age was 20.8±1.3 years. Of the total, 324(39.8%) students were from the public sector, while 490(60.2%) were at private colleges. A statistically significant difference was noted in professional and personal reasons cited by the two groups of students (p<0.05). Conclusion: It is of utmost importance that students shall be very clear regarding their expectations from a career to minimise chances of abandoning it midway or being professionally dissatisfied even after completing a degree.

It is most commonly seen in maxillary arch with female patients being mostly effected. The lesion varies in size from only a few millimeters to extending to involve the entire quadrant. The clinical management of denture induced hyperplasia depends upon the size of lesion and involves the elimination of causative factors, excision of excess fibrous tissue accompanied by an appropriate prosthetic rehabilitation. This case series presents the management of denture induced hyperplastic lesion of varying sizes present in maxillary arch by providing appropriate tissue rest and tissue conditioning as well as by surgical excision followed by new denture fabrication to achieve acceptable function for patients.

However, the work on fluoride release from GIC containing fluoroapatite and hydroxyapatite is scarce. Therefore, this study was conducted to find out the amount of fluoride release from Glass ionomer cement containing fluoroapatite and hydroxyapatite. METHODS The study was conducted in the Department of Materials, Queen Marry University of London. A total of 108 samples equally divided in to three groups namely fluoroapatite added GIC, Hydroxyapatite added GIC as an experimental group and unmodified GIC as a control group. The specimens were prepared by mixing powder and liquid in the ratio of 1:1. Amount of fluoride released was measured by Ion electrode method at 1, 3, 7, 14, 21 and 28 days. RESULTS On day 1, the combination of FA +GIC showed the highest amount of fluoride release followed by the control group (GIC) whereas the combination of HA+GIC released the least amount of fluorid...

Many surveys have been carried out internationally, but no survey has been carried out locally to ascertain practice of dentists when treating paediatric patients. Therefore, it appears important to map features of Paediatric Dentistry practice in our country. The purpose of this study was to assess practice regarding pulpotomy of primary teeth among dentists of Karachi and to compare difference in pulpotomy practice of primary teeth between private practitioners and teaching dentists. METHODS Questionnaire was distributed by hand to dentists working in private clinics and teaching hospitals of Karachi, involved in treating primary teeth of children. Questions captured information on aspects related to pulpotomy procedure as carried out by dentists. Descriptive statistics and frequency distribu...

Materials & methods: Electronic databases (National Library of Medicine [Medline by PubMed], Cochrane Library [Wiley], CINAHL [EBSCO] and Medline [EBSCO]) were systematically searched up to December 2019. Randomized controlled clinical trials comparing ABM/P-15 grafts to conventional surgery for intrabony and gingival recession defects were included and evaluated intrabony defects including clinical attachment level (CAL), probing depth and gingival recession. Results: A significant gain in CAL (1.37 mm), and reduction in probing depth (1.22 mm) were shown by ABM/P-15 grafts than open flap debridement (p < 0.00001). The subgroup analysis also showed better results for ABM/P-15 grafts in CAL gain for intrabony defects. For furcation and gingival recession defects, no significant difference was seen. Conclusion: The adju...

Methods: The Cochrane Library (Wiley), PubMed by Medline (NLM), Medline (EBSCO), and Embase (Ovid) databases were searched for entries up to April 2020. Only clinical trials were included. Primary outcomes were root coverage (%), changes in keratinized tissue width and recession (mm). Meta-analysis was conducted for root coverage, changes in keratinized tissue width, recession, clinical attachment level and probing depth. Results: Four studies were selected for the analysis. In primary outcomes, root coverage, change in keratinized tissue width and recession analysis showed a mean difference of 4.99% (p = 0.11), 0.20 mm (p = 0.14) and 0.13 mm (p = 0.23) respectively between the two groups.

Samples were fabricated using CHCAR (control Group A; n=114) and RRHCAR (experimental Group B; n=114). Group A and B were further divided into subgroups according to processing techniques: ACO, DHO and WB (n=38 each) for both testing variables microhardness and impact strength (n=19 each). Charpy testing machine and Vickers microhardness tester were utilized. Analysis of variance was applied to determine the presence of significant differences among processing techniques while P-value ≤ 0.05 was considered as significant. Water bath (P-value [0.001) and DHO technique (p-value [0.001) showed significant differences between both groups� impact strength and microhardness....

METHODOLOGY: In this prospective case control study, a total of 652 patients who had crown and bridge for not less than six months were included. The gingival margin location preference and reasons behind choosing a particular gingival margin was asked from the patients. Additionally, the teeth with and without restoration were also examined for periodontal health. Split mouth technique was used as unrestored, healthy contra lateral teeth in the same individual served as controls. Descriptive statistics and Chi square test were used for analysis to formulate the results. RESULTS: Ironically, 92% patients were not given a chance by their dentist to give input about margin location preference. The majority of patients preferred equi gingival margin for their anterior crowns 495 (75.92%) and supra gingival margin 58...

All patients were examined for vibrating line clinically, assessed using phonation method. Subsequently, distance between vibrating line and fovea paltatinae was measured with uncalibrated compass in various contours of soft palate. Results: Out of 197 patient, the vibrating line was seen in130 (64%) anterior to fovea palatinae, whereas, 67 (34%) vibrating line was at the fovea palatinae. The mean distance of those anterior located vibrating line from fovea palatine was calculated as 2.13 (±0.82) mm in Class, 2.07 (±0.69) mm in Class II and 1.80 (±0.82) mm in Class III soft palate contours.
