Distribution And Types Of Artificial Crowns And Bridges Prescribed At Nigerian Teaching Hospital

Objective; to determine the and distribution of artificial crows and fixed partial dentures, to analyse the age and gender distribution of patients receiving these pros these and to result with studies elsewhere Materials and methods: The present study consists of patients who received crowns and fixed partial dentures from January 1998 to December 2002, at the Hospital of the Obafemi Awolowo University Teaching Hospital Complex lle lfe, Nigeria. Result: total of 380 crowns were prescribed and fabricated 224 patients (F = 108, M= 116), giving an average of 1.7 crowns per patient. The majority of the crowns were fabricated patients in the age group 20 – 29 yeas. There were no statically crowned tooth was the maxillary central incisor constituting 59.7 per cent. All – resin crowns were the most prescribed (59.2 per cent) followed was porcelain – fused to – metal crowns (38. 1 per cent). A total of 68 fixed partial dentures, consisting of 178 retainers and 117 poetics made for 68 patients Conclusion: Although the pattern of distribution was similar to that reported in the western world, there was discrepancies in the age distribution. While in the western western world patients who received crowns on the average 4 years younger than those who received fixed partial dental dentures, in the study they were on the average 10 years younger. It may be that people in the western world more teeth earlier in life than in Nigerians Key Words: Artificial crowns, distribution, epidemiology Nigerian Journal of Clinical Practice Vol.7(1) 2004: 24-2

Root surface caries occurrence, oral hygiene status and habits in a selected suburban population, Ile-Ife, Nigeria

Objectives: The study evaluated root surface caries (RS C) occurrence in relation to oral hygiene status and habits in a suburban Nigerian Population.Methods: Seven hundred and twenty consecutive subjects, aged 20 years and above of both genders, attending the General Outpatient Department (GOPD) of Obafemi Awolowo University Teaching Hospital Complex (OAUTHC), Ile-Ife, Nigeria, were recruited. RSC was scored with Banting's diagnostic convention and Oral Hygiene Status (OHS) with Oral Hygiene Index – Simplified (OHI-S). Results: RSC prevalence figure was 11.6%. While the association between RSC and OHS was significant (P 0.05). RSC occurrence increased with advancing age. Frequency of tooth cleaning was not significantly associated with RSC occurrence, and being male or female had no significant effect on RSC occurrence. Conclusion: Within the limitations of the study, though RSC does not seem to be a serious public health problem in the studied population, Oral Health Education campaign should be adopted for preventive and early care.

Clinical evaluation of desensitizing treatments for cervical dentin hypersensitivity

The aim of this study was to compare different treatments for dentin hypersensitivity in a 6-month follow-up. One hundred and one teeth exhibiting non carious cervical lesions were selected. The assessment method used to quantify sensitivity was the cold air syringe, recorded by the visual analogue scale (VAS), prior to treatment (baseline), immediately after topical treatment, after 1 week, 1, 3 and 6 months. Teeth were randomly assigned to five groups (n = 20): G1: Gluma Desensitizer (GD); G2: Seal&Protect (SP); G3: Oxa-gel (OG); G4: Fluoride (F); G5: Low intensity laser-LILT (660 nm/3.8 J/cm²/15 mW). Analysis was based on the non-parametric Kruskal-Wallis test that demonstrated statistical differences immediately after the treatment (p = 0.0165). To observe the individual effects of each treatment, data was submitted to Friedman test. It was observed that GD and SP showed immediate effect after application. Reduction in the pain level throughout the six-month follow-up was also observed. In contrast, LILT presented a gradual reduction of hypersensitivity. OG and F showed effects as of the first and third month respectively. It can be concluded that, after the 6-month clinical evaluation, all therapies showed lower VAS sensitivity values compared with baseline, independently of their different modes of action
