“…A study suggested an obvious MIH prevalence decline when the children were older than 10 years old. Similarly, this pooled analysis confirmed that children age younger than 10 years old had higher prevalence of MIH than those who are more than 10 years old.…”

“…Molar incisor hypomineralization (MIH) is the hypomineralization of systemic origin of one to four permanent first molars, frequently associated with affected incisors. [ 1 2 3 ] It is a qualitative defect of the enamel. It is also called as hypomineralized permanent first molars (PFMs), idiopathic enamel hypomineralization, nonfluoride hypomineralization, and dysmineralized PFMs.…”

“…[ 5 ] It is clinically presented as white to yellow to brown demarcated enamel opacities of different colors, occasionally undergoing posteruptive breakdown due to soft and porous enamel. [ 2 3 6 ] Posteruptive enamel breakdown is a defect that indicates a decrease in the enamel depth after eruption. The posteruptive breakdown exposes the dentin which is very sensitive, and because of this, the tooth becomes vulnerable to rapidly progressing caries as the children cannot carry out oral hygiene very effectively.…”

Background:Molar incisor hypomineralization (MIH) is the hypomineralization of systemic origin of one to four permanent first molars, frequently associated with affected incisors. It is presented as demarcated enamel opacities of different colors, occasionally undergoing posteruptive breakdown. The characteristic feature of MIH is the clear demarcation between the affected and sound enamel. There is asymmetry of defects present in the molars and incisors where one molar or incisor can be severely affected, while the contralateral tooth may be clinically sound or have only minor defects.Aim and Objective:The aim of this study is to evaluate schoolchildren of 7–12 years of age with at least one of the first permanent molars fully or partially erupted from randomly selected government and private schools in Chennai using the European Academy of Pediatric Dentistry (EAPD) criteria for MIH, to determine the prevalence and characteristics of MIH.Materials and Methods:The dental examinations were performed in the classroom using a mouth mirror and explorer under a headlight. Teeth were wiped with gauze when necessary to remove plaque or the food accumulations. Surfaces that were examined were the buccal, lingual, palatal, and occlusal surfaces of permanent first molars and labial surfaces of upper and lower incisors. A single examiner was involved to avoid interexaminer bias. All the data were collected and scored using the EAPD criteria for MIH.Results:A total of 22 (12.9%) children out of the examined 170 had MIH.Conclusion:Distribution of MIH was more in males, more in 9 years of age. A total of 13 children had first molars affected and 9 children had both incisors and molars affected. Molars were affected more than the incisors. Mandible was affected more in comparison with the maxilla. Right side was affected more than the left side. The distribution of MIH was more in government schools compared to private schools.

“…reported a frequency of 7.11% in the children of Nagpur, Mittal and Bharat reported a prevalence of 10.48% in school children residing in Ghaziabad, and Anjum and Sudhan reported a prevalence of 14.9% in children from Jammu. [345678] The secretory phase of the ameloblast is most susceptible to the external environmental factors resulting in a variety of defects. Thus, DDE once formed have a limited ability for alteration.…”

Dental enamel is a unique, highly mineralized tissue of ectodermal origin. It is characterized by lack of metabolic activity once formed, implying that disturbances during development can manifest as permanent defects in the erupted tooth. Although the etiology of enamel defects may be attributed to local, systemic, genetic, or environmental factors, most are likely to be multifactorial in nature. The time frame of exposure and the mechanism underpinning the causative factors determine the presentation of these defects. These developmental defects of enamel (DDE) may range from slight abnormalities of the tooth's color to a complete absence of the enamel, some of which may be sensed by an individual as being disfiguring and call for treatment to improve the appearance of the dentition. Molar incisor hypomineralization (MIH) is a relatively common condition that varies in clinical severity, remains localized to permanent incisors and first permanent molars, and whose prevalence varies between 2.8 and 25% depending upon the study. Adhesion and retention of resin restorations is challenging in long-term rehabilitation in these cases. This paper presents a novel approach in the functional and esthetic rehabilitation of a 13-year-old female child diagnosed with multiple DDEs.
