Abstract

The objective of this study was to investigate and analyze the most common reasons for patients visiting Khyber College of Dentistry, Peshawar Khyber Pakhtunkhwa, for dental treatment rather than visiting other dental care centers and private clinics. About 300 patients who visited Khyber College of Dentistry during the period from 20^th October 2010 to 5^th November 2010, irrespective of gender, were interviewed using a specially designed questionnaire. They were asked to give feedback regarding different reasons for undergoing treatment at this hospital. Males (40%) were remarkably dominated by females (60%) in this study, with 1:1.5 ratios. Patients in their 3^rd decade (41.43%) were frequently interviewed followed by 4^th decade (20%). Majority of these patients were illiterate. Most of the patients responded that they visited this hospital because of feasible access. 37.14% were referred by their relatives and Doctors (n=40, 28.57%). In response to a question regarding past experiences, 52.86% patients had a satisfactory experience with this hospital. Khyber College of Dentistry is attracting more patients in terms of quality and care. The future of this institution will be built on these bases to improve the delivery of dental care. Patients are directly accessing information on new technologies and treatment methods.

Key words: Khyber College of Dentistry, dental treatment.

Abstract

With the growing awareness of esthetics the use of bleaching agents are on the increase. Bleaching agents intended to be used at home affects the existing restorations. The aim of the present study was to evaluate the effect of bleaching with carbamide peroxide agents at concentrations 10 and 22% on the microhardness and shear bond strength of composites and compomers. For microhardness and shear bond strength evaluation, samples of both composite and compomer restorative materials were subdivided into control group (stored in artificial saliva), Experimental groups bleached with 10% CP and those bleached with 22% carbamide peroxide. Following 2 weeks of bleaching treatment, Vickers’s hardness number was noted for each test specimen using a microhardness meter. For shear bond strength evaluation, the specimens were subjected to shear test under Instron universal testing machine. One way Analysis of Variance (ANOVA) was used for multiple group comparisons followed by Tukey’s test for pair wise comparison. Bleaching with carbamide ceroxide at concentrations 10 and 22% caused reduction in hardness of composite restorative materials. However bond strength of both composite and a compomer restorative material was not affected following bleaching treatment. Hence it can be deduced that bleaching caused reduction in hardness of composite restorative materials.

Key words: Carbamide peroxide, bleaching, restoration, bonding, microhardness, composite resins, compomer.

Abstract

Prescription 1.1% sodium fluoride (NaF) dentifrices designed to either have fast dispersion for improved enamel fluoride uptake (that is, PreviDent® Booster 5000) or contain an innovative tricalcium phosphate system for enhanced remineralization (that is, Clinpro® 5000) were evaluated for anticaries potential in an in vitro pH cycling model. Polished bovine enamel specimens were initially softened in a white- spot-forming solution comprising 0.1 M lactic acid plus 100 kDa polyacrylic acid (PAA, pH = 5.0) for 26 h at 37°C. Specimens were then measured for baseline Vickers microhardness and stratified (N =into the following groups: Group A: Tom’s of Maine fluoride-free dentifrice (negative control); Group B: Colgate PreviDent® Booster 5000 (5000 ppm fluoride) and Group C: 3M Clinpro® 5000 (5000 ppm fluoride). The groups were then cycled for 10 days in a pH cycling model consisting of four one-minute treatment periods (diluted 1:3 with distilled water) and one four-hour acid challenge (lactic acid-PAA , pH = 5.0) per day. Between these events, specimens were immersed in artificial saliva (pH = 7.0). After 10 days of cycling, the specimens were evaluated for Vickers surface microhardness, mineral loss and lesion depth using microindentation, transverse microradiography and polarized light microscopy. For all analyses, statistical differences (t-tests, p<0.05) were found to exist among the groups, with Clinpro® 5000 conferring superior surface and subsurface remineralization potential relative to both PreviDent® Booster 5000 and Tom’s of Maine fluoride-free paste. Due to this superiority, these results suggest the combination of 5,000 ppm fluoride plus the tricalcium phosphate system may provide significant anticaries benefits relative to fluoride-only and fluoride-free dentifrices.

Abstract

The study determined the incidence of flare-up and the effect of visit type, treatment duration, pre-operative pain, etc. on flare-up in adults. One hundred and seventy five participants, aged 18 to 60 years with a necrotic central incisor, with or without pre operative pain, participated in the study. They received post operative paracetamol tablets and were asked to report back if unbearable pain/swelling developed. A 10% flare up rate was recorded, while none of the studied factors had a significant relationship with flare-up, except intra operative pain.

Key words: Flare-up, preoperative pain, treatment duration, visit type.

Abstract

To determine the most frequent type of removable prostheses requested by patients who presented to the University of Benin Teaching Hospital outpatient clinic a descriptive retrospective study was carried out for all patients attending the Prosthodontic out patient clinic, who requested for removable prostheses from January 2004 - October 2008. The source of data was the clinic’s log book and patients’ case notes. Exclusion criteria are; request for obturators, mouth guard and palatal feeding plates for cleft lip and palate patients. Data of interest were: sex, age, edentulous space to be restored and reason for restoration. Data was analyzed using statistical package for social sciences version 13.0 and presented as a simple frequency table. A total of 351 cases were seen during the study period. This was made up of 188 (53.6%) males and 163 (46.4%) females. The age ranges were < 20 years (1.4%), 21 - 40 years (68.9%), 41 - 60years (19.9%) and 61 - 80years (9.8%). Edentulous spaces restored in these patients were Kennedy’s class III (57.3%), Kennedy’s class IV (26.2%), Kennedy’s class I and II (0.9%), Kennedy’s class III with modifications (5.7%), Kennedy’s class II with modifications (1.4%), Kennedy’s class I with modifications (1.7%) and complete dentures (6.0%). The main reason for seeking replacement was aesthetics (89.2%). The most common removable prostheses requested by patients who attend the University of Benin outpatient clinic was Kennedy’s class III, with aesthetics being the main reason for restoration of edentulous space.
