Prevalence and Clinical Characteristics of Molar–Incisor Hypomineralization in 8–16-year-old Children in Industrial Town of Solan District of Himachal Pradesh

Abstract

Aim The aim of the present study was to investigate the prevalence and etiology of molar–incisor hypomineralization (MIH) in 8- to 16-year-old children from town (Baddi) of Himachal Pradesh. Materials and methods A cross-sectional study was conducted with 2000 children from various schools of Baddi. Molar–incisor hypomineralization was diagnosed on the basis of EAPD 2003 criteria revised in 2009. Results Prevalence of MIH found was to be 2.9%. Demarcated opacities were predominant among all the defects. Postnatal illnesses were highly associated with MIH. The prevalence of dental caries reported in MIH patients was 82.7%. Conclusion Postnatal illnesses are significantly associated with MIH. Molar–incisor hypomineralization predisposes the tooth to dental caries.

A clinical and statistical study on enamel hypomineralization of the first permanent molar in the period of mixed dentition

“…Of the affected children, 71.4% presented mild lesions, 22.9% moderate defects and 5.7% the severe type. Similar prevalence rates in relation to severity were reported by Thakur et al (2020): 71.5% for demarcated opacities, 19.6% for post-eruptive enamel breakdown and 8.9% for atypical restorations, in 2000 Indian patients, 8-to 16year-old, but the overall prevalence was very low as compared to the one in the present study, 2.9% [50]. Comparable results on MIH severity pattern with those in the present research were obtained by Oyedele et al (2015): the mild form was the most prevalent, in 80.8% of the cases, followed by the moderate form, in 14% of the cases, and severe form in 5.2% of the cases [51].…”

“…In a study by Kemoli (2008), in 6- to 8-year-old children in two rural areas in Kenya, the ratio between affected girls and boys was even 3:1 [ 56 ]. On the contrary, MIH lesions were more prevalent in males than in females as shown by Thakur et al (2020) [ 50 ], Silva et al (2020) [ 52 ], Emmatty et al (2020) [ 53 ]. Equal distribution of MIH affected children in relation to gender was found by Preusser et al (2007) [ 45 ].…”

“…Thus, the prevalence rates obtained by Saitoh et al (2018) were: 22.2% in 7-year-old subjects, 19.9% in 8year-olds and 17.0% in 9-year-olds [41]. Thakur et al (2020), detailing MIH children according to age, found that amongst 58 MIH affected subjects, 32.8% were 8-year-old, 17.2% belonged to 9-year-old group, 15.5% were 10-year-old, 10.3% were in the age 11 year, 20.7% in the age 12 year and 3.4% were 13-year-old [50]. The older subjects (14-to 16-year-old) did not present MIH lesions, as reported by Thakur et al (2020) [50].…”

“…Thakur et al (2020), detailing MIH children according to age, found that amongst 58 MIH affected subjects, 32.8% were 8-year-old, 17.2% belonged to 9-year-old group, 15.5% were 10-year-old, 10.3% were in the age 11 year, 20.7% in the age 12 year and 3.4% were 13-year-old [50]. The older subjects (14-to 16-year-old) did not present MIH lesions, as reported by Thakur et al (2020) [50]. Koruyucu et al (2018) described a significant difference between 8-and 11-year-old subjects diagnosed with MIH from a sample of 1511 children in Istanbul, the former representing 9.9% and the latter representing 18.2% of the total MIH affected individuals [54].…”

The prevalence and characteristics of molar-incisor hypomineralisation in Natal, Brazil

“…Today, abundant data on the prevalence of MIH are available [9,10]. Clinical characteristics and prevalence rates of MIH have been reported in children and adolescents in different countries [11,12], as the early detection of enamel defects allows the paediatric dentist to de ne preventive care, for the preservation of the tooth, and greater involvement of caregivers in the long-term follow-up [13].…”
