Objective: To compare the effectiveness of Carbamazepine versus Topiramate for the management of trigeminal neuralgia. Study Design: Comparative prospective study. Place and Duration of Study: Oral and Maxillofacial Surgery department, Allied Hospital, Faisalabad Pakistan, from Nov 2017 to Nov 2018. Methodology: A total of 60 patients (30 in each group) were included. Group A was treated with Carbamazepine 100mg TDS and group B with Topiramate 25mg TDS. Visual analogue scale was used to access pain and was calculated at 1st visit (baseline), at 7th day, at 14th day and at 28th day. Results: Out of 60 patients, mean of age was 54.78 ± 8.49 years. Right and left side of the face was involved in 41 (68.3%) and 19 (31.7%) patients respectively. Maxillary branch was involved in 24 (40%) and mandibular branch was involved in 36 (60%) patients. The mean of visual analogue scale after 7 days in group A was 4.53 ± 0.93 and in group B was 7.1 ± 1.07, after 14 days mean of visual analogue scale in group A was 3.7 ± 1.02 and in group B was 4.03 ± 1.27. Mean of visual analogue scale after 28 days in group A was 3.27 ± 1.01 3.93 ± 1.28. The results were statistically significant with p-value of 0.03. Conclusion: Topiramate has comparable efficacy as that of Carbamazepine at dose of 75-100mg with lesser side effects. So Topiramate can be used as first line of treatment in trigeminal neuralgia.

Objective: To evaluate the knowledge and attitude of dental students towards hepatitis B infection. Study Design: A Cross Sectional Study (survey).

Introduction: Erosion is an escalating problem in all age groups. Dental erosioncan be defined as painless irreversible loss of dental hard tissue due to chemical processwithout the involvement of microorganisms. There are several causes of erosion includingacidic foods and drinks. They are not only harmful to teeth but it is one of the main causes offailure of restoration. Erosion is one of the main challenges to restorative materials. Therefore,the restorative materials used in the mouth should resist or show minimal change in thesesituations. A variety of restorative materials are currently recommended for erosive lesions,including resin modified glass ionomer cement, resin composite and amalgam. Each materialhas its own advantages and disadvantages, which are considered before selecting them asrestorative materials. Objectives: To compare the surface micro-hardness of three restorativematerials when exposed to three acidic beverages and distilled water. Study design: This wasan experimental study. Setting: de’Montmorency College of dentistry in collaboration withPakistan council of scientific and industrial research (PCSIR) Lahore. Period: 6 months, Nov2014- April 2015. Material & Methods: Ninety six disc specimens prepared with resin modifiedglass ionomer, resin composite and amalgam restorative materials. The initial surface microhardnesstest was carried out at 1 day after mixing (before immersion) using micro-hardnesstesting machine. After base line study of micro-hardness the material specimens were subjectedto one of the storage media which was comprised of cola, apple juice, orange juice and distilledwater as control. Quantitative assessment of final surface micro-hardness was done at 2, 5 and7 days after immersion. The values obtained as base line and final vickers hardness number(VHN) for each specimen were subjected to statistical analysis. Results: Exposure to acidicbeverages decreased the surface micro-hardness of all the three restorative materials (P<0.05),while distal water did not affect the surface micro-hardness of any material. The resin modifiedGIC showed greatest reduction in surface micro-hardness as compared to Amalgam and ResinComposite. The cola produced the greatest degradation effect. Conclusion: Selection ofrestorative materials should be considered in patients with tooth surface loss, especially thosewith high risk for erosive conditions. In terms of materials evaluated for this study Amalgam andResin Composite provides the greatest stability under acidic conditions.

To establish the etiology, pattern, management and outcome of maxillofacial trauma in pediatric patients. METHODOLOGY: A three-year record of pediatric patients who suffered from maxillofacial trauma was reviewed and analyzed using hospital database. The data gathered from the record of the patients like age was presented as mean and standard deviation whereas data like gender, etiology of particular trauma, anatomic position of fracture, affiliated injuries, kind of treatment used and outcome of the treatment was presented as frequency and percentage. Study Design: Retrospective study.
