Title: Assessment of Crown and Bridge Work Quality among Sudanese Dental Practitioners in Khartoum State
Author: Babiker Mohamed, Ahmed
Abstract: The aim of this study to investigate the quality of crown and bridge work among dental practitioners (DP's) in Khartoum state by mean of a questionnaire. This was distributed to 230 individual DP's who work in private clinics or primary health care centers in Khartoum state. A total of 152 completed questionnaire forms were collected, giving a response rate of 66.09%. The crown and bridge work was mainly done in private practice (80.92%) in comparison to primary health care centers (19.08%). Thirty two percent and 38.1% of the surveyed DP's never or rarely used study casts respectively. The surveyed DP's often (40.94%) and rarely (35.57%) use radiographs for the crown and bridge work. Vitality test of abutment teeth was never (45.64%) or rarely (22.82%) done by the majority of the surveyed DP's. High-speed hand pieces were the instrument of choice in 80.54% of the responses. The most common used hand pieces according to number of spray ports were found to be the single port (80.43%). Impression materials used by surveyed DP's were as follow: additional cured-silicone 7.32%, condensationcured silicone 24.32% and alginate 68.24%. The putty and wash technique was the most recommended technique for those who used silicone impression material (80.85%). Impression trays used by DP's were: metal 23.53%, rigid plastic 12.5% and both 63.97%. Results in relation to the use of the retracting cord indicated that 53.69% never use it, while 9.4% always used it in their practice. Disinfection of the impression was not routine. Wax was the most commonly used interocclusal recording material (94.34%). Both verbal and written prescriptions (81.73%) was the most common way of communication between DP's and dental technicians. Results also showed that 36.05% never used temporary restorations before cementation of the definite restorations. Traditional glass ionomer cements and zinc phosphate cements were the most commonly selected material for the luting crown and bridge restorations. It is concluded from the present investigation that the majority of the surveyed DP's rarely used study casts and radiographs for the abutment teeth. 6 It is also, concluded that alginate was the main impression material used for crown and bridge work. The rare use of retraction cords, disinfection of the impressions and the use of temporary restorations was observed. The data obtained from the present study is a cause for concern for the standard of crown and bridge work in Khartoum state specially and in Sudan in general
