Diş çürüğü ve mine bozuklukları, çocuklarda çok yaygındır. Mine hipomineralizasyonu, çürük gelişimini ve çürüğün şiddetini artırabilen mine bozukluklarından biridir. Süt ikinci azı hipomineralizasyonu, minenin gelişimsel bir bozukluğu olmasının yanında büyük azı kesici hipomineralizasyonu (BKH) ile benzer klinik özelliklere sahiptir. SAH, klinik olarak 1-4 adet süt 2. azı dişi etkileyebilen, minede tipik olarak sarı-kahverengi renklenme ve belirgin bir opasite olarak tanımlanmaktadır. Süt 2. azılarda gözlenen, sınırları belirgin hipomineralizasyon varlığının, daimî dişlerde BKH görülmesinin bir işareti olabileceği bildirilmiştir. Diş sert dokularında meydana gelebilecek hızlı yıkımların, akut semptomların ve tekrarlayan tedavilerin önlenmesi açısından hipomineralizasyonun erken teşhis edilmesi önemlidir. Süt ve daimî dişlerde hipomineralizasyon varlığı; diş çürüğü, hassasiyet, ağrı, estetik kaygı ve diş yüzeyi kaybına neden olarak, çocuğun yaşam kalitesini olumsuz yönde etkileyebilir. Mine hipomineralizasyonlu tüm dişlerin tedavi yaklaşımında öncelikli olarak diş çürüğünün oluşumu önlenmelidir. Süt ikinci azı hipomineralizasyonu varlığı BKH'ye işaret edebileceğinden, veliyi konu hakkında bilgilendirmek, hijyen ve beslenme eğitimi vermek ve özellikle daimî 1. azıların sürme döneminde hastaları sık kontrollere çağırmak gerekmektedir. Bu tür dişlerin tedavi yaklaşımında etkilenen dişlerin tipi, defektlerin büyüklüğü ve şiddeti, diş yüzeyi kaybı ve ilişkili semptomlara bağlı olarak kısa ve uzun dönem tedavi planları gerektiren birçok restoratif yaklaşım bulunmaktadır. Bu kısa literatür derlemesinde, Süt ikinci azı hipomineralizasyonunun karakteristik özellikleri, görülme sıklığı, etiyolojisi, tanı kriterleri ve ayırıcı tanısı, klinik önemi ve tedavi yaklaşımı mevcut literatür ışığında değerlendirilecektir.

Dental caries and enamel defects are very common among children. Hypomineralization is one of the enamel defects that can increase caries experience and severity. Hypomineralization of second primary molars (HSPM) a developmental defect of dental enamel and has similar clinical features with molar incisor hypomineralization (MIH). HPSM typically present as white, yellow or brown demarcated opacities in the enamel, affecting one to four primary second molars. The presence of demarcated molars hypomineralization of second primary molars has been cited as a predictor of molar incisor hypomineralization. Early diagnosis is essential to prevent rapid breakdown of tooth structure, acute symptoms and repeated treatments. Hypomineralization in the primary and permanent dentition can result in dental caries, hypersensitivity, pain, esthetic concerns, and tooth surface loss, therefore, affecting the child's quality of life. The prevention of dental caries is essential in the management of all patients with hypomineralized enamel. The presence of HSPM can be considered as a predictor of MIH, indicating the need for informing the parents, managing the oral hygiene and diet, control the patients regularly regarding MIH especially during the eruption of the first permanent molars. Many restorative techniques for the management of such teeth are available that might require short and long management treatment plans depending on the type of teeth affected, extent and severity of defects, tooth surface loss and associated symptoms. In this mini-review, the characteristic features, prevalence, etiology, diagnostic criteria, differential diagnosis, clinical importance and treatment approach of hypomineralization of second primary molars will be reviewed in the light of the current literature.
