Furcation Perforation Treated with Mineral Trioxide Aggregate in a Primary Molar: Results after 15 Months

Abstract

Furcation perforation is an undesirable situation in primary teeth, and it may result in periodontal destruction and early shedding. Mineral trioxide aggregate (MTA) has been used in repairing of root perforations and furcation perforations in permanent teeth, but rarely used in primary teeth. A 4 years 7 months-old boy was referred to our hospital for the treatment of persistent buccal abscess over his primary mandibular left secondary molar. The periapical x-ray and clinical examinations showed furcation perforation on the tooth. After management with root canal treatment, MTA was placed over the perforation site and the tooth was then restored with stainless steel crown. The tooth was asymptomatic and the radiolucent furcal lesion subsided following the treatment. After 15-month follow-up, the tooth remained asymptomatic and the furcal crestal bone healed. Therefore, MTA may be suggested as a suitable material for the repair of furcation perforation in primary molar teeth.
