|Objectives: This study analyzed the use of amalgam and resin composite for posterior restorations placed by general dentists in relation to dentist, patient and cavity factors. Methods: One thousand posterior restorations (n=1000) placed by a representative sample of general dentists working in the Ministry of Health (MOH) Kuwait during routine clinical practice were assessed and information about the restorations was recorded using a survey questionnaire. Descriptive statistics and binary logistic regression analysis were used to determine the factors associated with the use of amalgam versus tooth colored restoratives. Results: Dentists chose amalgam for 30.8% of the 1000 restorations. Dentists with longer experience (>15 years) were more likely to choose amalgam (OR=3.78, 95% CI=1.52, 9.38). Amalgam was more likely to be chosen for patients with poor oral hygiene (OR=1.58, 95% CI=1.08, 2.32) and a high number (≥4) restorations (OR=1.44, 95% CI=1.07, 1.94) with large cavity sizes (OR = 6.33, 95% CI = 3.88, 10.32). Tooth colored restorations were more likely to be chosen for small cavity sizes. Conclusions: The use of resin composite materials as the dominant choice among dentists in Kuwait reflects the trend worldwide. Nevertheless, clinicians still find a use for amalgam in posterior load-bearing teeth and in the high-caries risk population.|
