چکیده

مقدمه: مولر انسیزورهایپومینرالیزاسیون ، جهت توصیف نقایص تکاملی مینا به کار می رود تشخیص زود هنگام این نقیصه در افراد مبتلا ، مراحل و روند درمان را برای دندانپزشک و کودک ساده تر می کند . هدف از این مطالعه بررسی شیوع Molar-incisor hypomineralization (MIH) در کودکان 8-6سال شهر اصفهان بود
مواد و روش ها:در این مطالعه cross-sectional، 651کودک 6 تا 8 ساله (326 دختر و 325 پسر) شهر اصفهان از نواحی 6 گانه آموزش و پرورش به صورت تصادفی انتخاب شده و از معیار های تعیین شده آکادمی دندانپزشکی اروپا جهت بررسی شیوع مولر اینسیزور هایپومینرالیزاسیون در این کودکان استفاده شد. شیوع و رابطه بین این نقیصه و معیار هایی از جمله جنس ، سن ، میزان تحصیلات والدین و نوع مدرسه بررسی شد. داده ها با استفاده از آزمون های t-tests ، Mann-Whitney و chi-square تجزیه و تحلیل شد
یافته ها: شیوع MIHدر شهر اصفهان 2/21% بود. هیچ یک از فاکتور های دموگرافیک مانند سن ،جنس،نوع مدرسه و سطح تحصیلات پدر ومادر با شیوع MIHمرتبط نبوده و DMFTو dmft در این کودکان بیشتر از کودکان بدون نقیصه مینایی می باشد. بیشترین فراوانی ضایعات مربوط به اپاسیته های سفید – کرمی بدون شکستگی مینای دندان بود . شدیدترین نوع MIH بیشتر در دندان های مولر دیده شد.
نتیجه گیری: MIH در اصفهان از شیوع بالایی برخوردار است اما بیشتر ضایعات از نوع خفیف بوده و اقدامات پیشگیرانه،افزایش اگاهی ومعاینه منظم دندان ها در سال های اولیه رویش دندان های دائمی بسیار کمک کننده است

چکیده [English]

Introduction: Molar Incisor Hypomineralization (MIH) describes a developmental enamel defect that affects one or more permanent molars, with or without incisor involvement. Early diagnosis facilitates treatment procedures for dentists and patients. This study aimed to investigate the prevalence of MIH in 6- to 8-year-old children in Isfahan.
Materials and Methods: In this cross-sectional study, 651 children aged 6 to 8 years (326 girls and 325 boys) from Isfahan city were randomly selected from 6 education districts during the 2019-2020 academic year. The established criteria of the European Academy of Pediatric Dentistry were used to assess the prevalence of molar incisor hypomineralization. The prevalence and relationship between this defect and criteria such as gender, age, parental education level, and type of school were investigated. Data were analyzed using Independent T-tests, Mann-Whitney, and Chi-square (α = 0.05).
Results: The prevalence of MIH in Isfahan was 21.2%. None of the demographic factors, such as age, sex, type of school, and parental education level, were associated with the prevalence of MIH. DMFT and dmft were higher in these children than in children without enamel defects. The highest frequency of lesions was related to white-cream opacities without enamel fractures. The most severe type of MIH was seen more in molar teeth.
Conclusion: MIH is highly prevalent in Isfahan, but most lesions are mild, and preventive measures, increased awareness, and regular dental examinations in the early years of permanent tooth eruption are very helpful.
