Abstract

BackgroundThis study aimed to identify the prevalence of oral co-morbidities in 8 to 16 years old children with Molar Incisor Hypomineralisation (MIH) and compare this with the prevalence of same oral lesions in children without MIH.MethodStudy participants were selected through a multi-staged sampling technique. The children were asked if they had dentine hypersensitivity or any concerns about their aesthetics. Children were examined for MIH, caries, traumatic dental injury and their oral hygiene status. The association between MIH and each of the independent variables was determined.ResultsOnly children with MIH had aesthetic related concerns and dentine hypersensitivity. The differences in the oral hygiene status (p < 0.001) and caries prevalence (p < 0.001) of children with and without MIH were statistically significant. The prevalence of traumatic dental injury did not differ statistically between children with MIH and those without MIH (p = 0.24).ConclusionChildren with MIH had more oral pathologies than children without MIH. These co-morbidities (dentine hypersensitivity, aesthetic concerns, caries and oral hygiene) are capable of impacting negatively on the quality of life of the children. Screening for children with MIH may help facilitate prompt access to treatment.

Highlights

This study aimed to identify the prevalence of oral co-morbidities in 8 to 16 years old children with Molar Incisor Hypomineralisation (MIH) and compare this with the prevalence of same oral lesions in children without MIH
Due to the difficulties in achieving adequate anaesthesia and the frequent treatments required, children with MIH run the risk of developing dental fear and anxiety [6]
This study shows that children with MIH had significantly more oral pathologies when compared with children without MIH: children with MIH reported experiencing dentine sensitivity, had concerns with the aesthetic appearance of their teeth, had more carious lesions and were more likely to have poor oral hygiene status

Summary

Introduction

This study aimed to identify the prevalence of oral co-morbidities in 8 to 16 years old children with Molar Incisor Hypomineralisation (MIH) and compare this with the prevalence of same oral lesions in children without MIH. The defective enamel can cause tooth sensitivity, disfigurement, rapid plaque retention, caries and its sequelea [6,7]. This causes considerable discomfort for the child, it can be of the affected molars are more difficult to anaesthetise due to the subclinical inflammation of the pulpal cells, resulting from porosity of the enamel, which allows bacterial toxins to penetrate and cause pulpal reactions [6]. Continuous disintegration of the enamel of the affected teeth, and difficulties with bonding with dental materials [8,9], suggests that children with MIH require extensive and often repeated restorative treatment, especially on the molars [6]
