Abstract
OBJECTIVES: This study prospectively analyzed the use of amalgam and resin composite posterior restorations placed by general dentists in relation to dentist, patient and cavity factors. METHODS: One thousand posterior restorations placed by a representative sample of general dentists working in the Ministry of Health (MOH), Kuwait, during routine clinical practice were included. Information about the restorations was recorded using a survey questionnaire. Descriptive statistics and multivariate logistic regression analysis were used to determine the factors associated with the use of amalgam versus tooth coloured restoratives. RESULTS: Dentists chose amalgam for 30.8% of the 1000 restorations. Dentists with longer work experience (>15 years) were more likely to choose amalgam (OR=2.61, 95% CI=1.06, 6.40). Younger dentists (≤30 years) were less likely to choose amalgam (OR=0. 45, 95% CI=0.26, 0.77). Amalgam was more likely to be chosen for patients with poor oral hygiene (OR=1.58, 95% CI=1.08, 2.32) and a higher number (≥4) of restorations (OR=1.44, 95% CI=1.07, 1.94) with large cavity sizes (OR=6.33, 95% CI=3.88, 10.32). Tooth-coloured restorations were more likely to be chosen for cavities of smaller 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. CLINICAL SIGNIFICANCE: The findings give insight into factors influencing material usage under different clinical conditions and provides information about the perceived deficiencies or shortcomings of resin composite materials in a general dental practice setting. This information can be useful for identifying perceived barriers to the usage of newer restorative materials and finding ways to overcome them.
