Abstract

Background: The aim of the study is to know the prevalence of hypomineralizations in second primary molars (HSPM) in 7to 10-year-old Saudi children. Materials and Methods: A Total of 596 school children of age group 7-10 years was screened for HSPM. Clinical examination was done inside the respective schools. Dental examination was carried out by using scoring criteria to identify for HSPM on we surface under the portable light source. The results were recorded and analyzed for statistical significance using the Chisquare test and t-test with a P-value of <0.05 considered significant. Results: In this study, 596 (80% males) of the 745 selected children participated. Causes for nonparticipation were not interested, lack of time, fearful child, language problems, not present, and other reasons. Distribution of HSPM according to the age of the children is shown in the In 32 (5.4%) children a second primary molar was seen with a demarcated opacity, an atypical restoration or posteruptive enamel loss, with a mean of 4.6 HSPMs per child. Among the 32 affected children, 9 had 1 HSPM, 11 had 2 HSPMs, 7 had 3 HSPMs, and 5 had 4 HSPMs. Conclusions: Children with a higher prevalence of HSPM, also suggests that HSPM is a predisposing factor for MIH. Several other studies also suggested that HSPM lesions were associated with carious lesion occurrence and increased disease severity. Increased awareness of HSPM in children and primary health settings may help to identify children at risk early.
