Abstract: Objective: To determine the clinical presentation, distribution of hypomineralized lesions in second primary molars, and the associated defects in the primary dentition in Jordanian children. Method: A prospective study was conducted on patients diagnosed with Hypomineralized Second Primary Molar who attended pediatric dental clinic at Prince Rashid Bin Al Hassan military hospital in the north of Jordan in the period between May and September of 2021. Collected data included gender, age, the severity of the lesions, and the presence of other hypomineralized lesions on the first primary molar and the primary canine. The criteria for the diagnosis of hypomineralized second primary molar and other primary teeth were based on the criteria of the European Academy of Paediatric Dentistry. Results: Two hundred and fifty-six patients were diagnosed with hypomineralized second primary molar with over a half of them had the severe form. Most of the affected children had either two or four hypomineralized second primary molars with a mean average 2.8/affected child. Hypomineralized first primary molar and hypomineralized primary canine co ? occurred with 57.4% of hypomineralized second primary molar cases, occurring more frequently when there were two or four affected second primary molars and with severely hypomineralized second primary molars. Conclusion: The findings in this sample which showed a high number of teeth affected per child and a high percentage of cases classified as severe cases are warning. Although the exact cause of hypomineralization in second primary molar and other primary teeth is not yet well known, early detection with a proper treatment plan assist in the control of the deteriorating effects that usually result from hypomineralization.
