Tooth decay is one of the most common preventable infections in childhood. Currently, the most effective way to reduce occlusal
caries is Pit and Fissure sealants. Since different factors, including knowledge, attitude and performance of dentists, can influence the
use of fissure sealant, this study aimed to evaluate the knowledge, attitude and performance of dentists in Ahvaz about pit and
fissure sealant application and techniques. In this descriptive cross sectional study, 147 dentists in Ahvaz selected by simple random
sampling. Data were collected using a two-part questionnaire. The first part of the questionnaire included the demographic
characteristics of the dentist (including age, sex, years of clinical experience, participation in retraining). The second part contained a
number of questions regarding the attitude, knowledge and performance of dentists about fissure sealant and its application. The
mean scores for knowledge, attitude were 9.1 ± 1.8, 33 ± 3.9, respectively. In terms of performance, 62.6% of dentists always, 62.6%
occasionally and 22.4% rarely used fissure sealant. Data were analyzed by T-test, chi-square, one-way ANOVA and Pearson
correlation coefficient and descriptive statistics. Analysis was performed using SPSS software. The results showed that dentists had
moderate knowledge and attitude about using fissure sealant in Ahvaz. So, training programs and emphasizing the importance of
sealant use in prevention of dental caries is recommended.
