Aim:The study aimed to determine the prevalence of HFPM and its correlation with caries in 4–6-year-olds children in Chennai, Tamil Nadu. 

Materials &Methods:The cross-sectional study was carried out among 370 children belonging to 4-6 years of age. The European Academy of Paediatric Dentistry (EAPD) criteria was utilised for scoring HFPM. The decayed, missing and filled teeth (dmft) index was used to evaluate the status of caries. 

Results: The prevalence rate of HSPM was 36.6%. No statistical significance was established on the basis on gender (Ƿ> 0.05). An odd’s ratio of 3.35 revealed that children with HFPM were more likely to develop dental caries (Ƿ<0.001). 

Conclusions:The proportionality of HFPM observation was high in children belonging to the Chennai city. HFPM increases the incidence of caries. 

Clinical Significance: The significant raise in the occurrence of HFPM in children and its likelihood in the causation of dental caries makes it fundamental to organise screening programs for the diagnosis and management of HFPM.
