INTRODUCTION: Molar-incisor-hypomineralization (MIH), a developmental defect that alters normal mineralization, causing permanent damage to the enamel. The affected enamel shows a reduction in mineral composition, calcium: phosphorus (Ca:P) ratio, and relatively increased carbon content. Among the numerous factors that affect the enamel integrity in MIH, the properties such as salivary and plaque pH might have an impact, but recent studies suggest only minimal data regarding the various factors, making it still obscure to the clinician.
AIM: To determine the salivary and plaque pH in 8-15-year-old children with and without MIH and to correlate it with caries severity in children with MIH.
MATERIALS AND METHODS: In this study, 209 children aged 8-15 years were selected by stratified sampling. Hypomineralized teeth and caries were assessed using the European Academy of Paediatric Dentistry (EAPD) criteria and International Caries Detection and Assessment System, version II (ICDAS II) criteria, respectively. Salivary and plaque samples were collected, and pH was determined.
RESULTS: Statistically significant difference in salivary pH was observed between the groups A1, A2, B, C, and A, B, C (p = 0.001*). On pairwise comparison, significant differences were observed in all pairs of groups except groups B and A. Statistically significant differences in plaque pH were seen between groups A2 and C (p = 0.001*). On pairwise comparison, significant differences were seen in all pairs of groups except groups A1, B, and A, B. The ICDAS II criteria scores were significantly higher in the MIH group.
CONCLUSION: Statistically significant increase in caries severity and a fall in the mean salivary and plaque pH associated with posteruptive enamel breakdown (PEB) in the MIH-affected population was observed.
