“…It is noteworthy to mention that Elfrink and colleagues stated that to conduct an MIH prevalence study a minimum random sample size of 300 is required 20 . Upon completing a literature review in regards MIH, a total of three other research carried out in Arab settings were identified, with the countries of context Iraq 23 , Jordan 24 and Libya 25 . These studies highlighted prevalence rates of 21.5%, 17.6% and 2.9%, respectively.…”

ABSTRACT:Objective: To evaluate molar-incisor-hypomineralization (MIH) prevalence, clinical characteristics, and severity amongst school children in Riyadh, Saudi Arabia. Subjects and Methods: Randomly selected, healthy third-and fourth-grade students (aged 8-10 years) attending elementary schools in Riyadh, and children of the same age attending dental clinics at the College of Dentistry, King Saud University, were examined for the presence of MIH, its clinical characteristics, and severity. Results: The sample studied consisted of 924 children, 447 (48.4%) of whom were boys. There were 376 children, (199 females and 177 males), with at least 2 index teeth affected (prevalence = 40.7%). A total of 133 (35.4%) had only molar hypomineralization (MH), whereas 243 (64.6%) had molars and incisors involved (MIH). The mean number of affected teeth per child was 6.6 ±3.6 (3.3 for molars and 3.2 for incisors). The chi-Square test showed no association between the distribution of hypomineralization and age (P = 0.115). Children with severe hypomineralization predominated across all age groups, with the 10-year-old group having more severely affected children (71.9%) compared to 8-and 9-year-old groups (P = 0.000). Proportional t-test showed no statistically significant difference (P>0.05) between males and females in the occurrence of MH or MIH, and in the severity of the hypomineralization. Upper molars were more affected than lower molars, whilst upper incisors were more affected than lower incisors. Conclusion: Enamel hypomineralization is a common feature in the dentition of 8-10-year-old children in Riyadh, Saudi Arabia. There is no association with age and no gender predilection.

“…In the present study, PFMs hypo-mineralization was similarly distributed between quadrants and arches which was consistent with some previous studies (Weerheijm et . Some of those researchers attributed the high prevalence in mandibular molars to the fact that differences in examination conditions may make it hard to view maxillary molars as clearly as mandibular molars (Mittal et al, 2016), and the early eruption with early posteruptive enamel breakdown or caries makes the mandibular more prone than maxillary molars (Zawaideh et al, 2011). On the other hand, Chawla et al, (2008) explained the higher prevalence of hypo-mineralization in the maxillary PFMs by the same reasons analyzed differently.…”

Aims. To evaluate the prevalence of and describe molar-incisor hypomineralization (MIH) in a group of female children in Riyadh, Saudi Arabia. Methods. The sample consisted of 8-10-year-old (n=682) female student"s attending female elementary schools and females of the same age attending pediatric dentistry clinics at the College of Dentistry, King Saud University, Riyadh. Subject"s permanent first molars (PFMs) and incisors were examined for demarcated opacities, post-eruptive enamel breakdown, atypical restorations and extraction due to MIH. Results. 277 children were affected by hypomineralization giving a prevalence rate of 40.6%. The mean affected teeth was 6.5±3.18 (3.8 molars and 2.7 incisors) per child. 46.9% had only molars hypo-mineralization (MH), while 53.1% had molars and incisors affected (MIH). Proportional t-test showed no statistically significant difference between the number of affected upper and lower molars, while upper incisors are affected more than lower incisors. Moderate/severe hypo-mineralization predominated in both MIH and MH with MIH children having more moderate/severely affected teeth. MIH prevalence has no association with the age, but ten-year-old have more moderate/severely affected teeth (P=0.041) than eight and nineyear-old children. Conclusion. The observed prevalence of MIH in Riyadh female children was high. Carefully planned short and longterm preventive and therapeutic programs and nationwide larger scale epidemiological studies are needed.

“…There was no significant difference with regards to gender. Mittal have shown that the prevalence rate in India is 6.31% [8], 2.8% in Hong Kong Cho [9], 17.6% in Jordan Zawaideh [10], 18.6% in Iraq [11], and 4% to 25% in Europe [3,4]. Regional differences might be correlated with the environment of child's growth and development, diagnostic criteria, statistical methods, and age.…”

Abstractobjective: The aim of this study is to investigate the prevalence and putative contributing factors of MIH in primary school students in Suzhou. Subjects and methods:A total of 1145 primary school students were selected for this study. The MIH prevalence survey and a questionnaire was performed in accordance with the MIH diagnostic criteria enacted by the European Association of Pediatric Dentistry (EAPD). Statistical analysis of the data was performed using SPSS13.0. Results:The overall prevalence rate was 4.45% with no gender difference. The primary clinical manifestation is demarcated opacities. The highest prevalence occurred in children with two affected molars and two incisors. The problematic teeth were usually symmetrical. MIH occurrence significantly related with whether the children suffered from otitis media and tonsillitis and whether they had used antibiotics in their first three years of life. MIH had no correlation with the children's family background, feeding methods, and the physical conditions of their mothers during pregnancy. Conclusion:The MIH prevalence in primary students was 4.45% with mild clinical symptoms. MIH prevalence was correlated with the children's medical history and use of antibiotics in their first three years.

Molar Incisor Hypomineralisation: prevalence in Jordanian children and clinical characteristics

Abstract: MIH was common among 7-9 year-old Jordanian children with a prevalence of 17.6% and was gender related. MH was more common than MIH and can be considered a mild form of an MIH spectrum. Majority of MIH and MH cases were mild in nature but demonstrated an agerelated severity.
