Title: Quality of Composite Restorations in Patients Attending the Faculty of Dentistry University of Khartoum
Author: Ijaimi,Zahir Abdullah
Abstract: Objectives: To evaluate the quality of the composite restorations in Khartoum. Methods: In this observational descriptive cross-sectional study, a total of 246 composite restorations in 125 patients attending the Conservative Dentistry Clinic at the Faculty of Dentistry, University of Khartoum were examined. Both anterior and posterior composite restorations were included. California Dental Association Quality Evaluation System was used for the evaluation. Results: Fifty two percent of all restorations found to be satisfactory, while the remaining 48% were not satisfactory. All examined teeth showed no tenderness to both vertical and horizontal percussion tests, and (76.4%) gave positive results to cold sensitivity test. The most frequent cavity class was class IV (31.3%). Ninety five percent of the restorations have acceptable surface and colour, 55.7% acceptable anatomical form and 88% have acceptable marginal integrity. With regard to surface and colour criteria, colour mismatch within the range (34.8%) and slight surface roughness (26.6%) were the most common defects. The most frequent defects of the anatomical form were restoration overhang (26.8%) and overcontour (13.8%). Marginal ditching not extending to DEJ (9.9%), marginal discoloration (12.9%), secondary caries (4.7%) and restoration fracture (3.9%) were the most encountered marginal integrity defects. Twenty percent of class II restorations have unacceptable marginal integrity. The majority of the restorations above 4 years old were of unacceptable anatomical form (66.7%), and their marginal integrity is less acceptable than more recent restorations (46.7%). Conclusions: Forty eight percent of the examined composite restorations need to be replaced, and the unacceptable anatomic form is the main cause of failure of composite restorations. The median longevity of the composite restorations was 2 V years, and (35%) of the examined restorations required an immediate clinical intervention. Operative techniques, types and quality of materials used, handling of materials according to the manufacturer's instructions and the level of the knowledge and skills of the Dental Practitioners are variables that affect the quality of the restorations and warrant further investigations
