Abstract
Dental practitioners today have many materials from which to select when restoring posterior primary teeth. The present study was carried out among dentists in public and private clinics in Alexandria to determine the frequency of different types of restorative materials used by pediatric and non-pediatric dentists and to identify factors influencing the selection of these restorative materials. The sample consisted of 127 dentists with a response rate of 82.47%.
A specially designed questionnaire included 28 multiple choices or yes/no format items and questions arranged in three sections as participant’s demographic information, dentist use of filling materials for patients under 12 years old and the role of parents in the treatment decisions for their children in the dentists’ practice. Data was collected in the period from April 2011 to May 2012.
The software SPSS (Statistical Package for the Social Science) for windows was used for the statistical analysis version 17.0. Descriptive statistics were displayed as frequencies and percent. The association between studied variables was assessed using chi square test, Fisher exact test or Monte Carlo test (as indicated). Bar charts and pie charts were used for graphical presentation.
The results showed that amalgam was the most available (100%) and used dental material for restoring primary molars while compomer was the least available (21.7%) and used dental material.
Amalgam was mostly used for restoring conventional class II preparation in primary molars (51.2%) while for large class II preparation, SSC (84.3%) was the most used material. Amalgam was used less frequently among pediatric dentists (84.5%) as compared with non-pediatrics (89.9%) with no significant differences.
The use of amalgam in primary molars restorations was affected by socioeconomic status where medium socioeconomic level showed the highest percentage (93%) of amalgam use.
