Abstract

We used the Isolite system for treatment of dental caries identified in a submerged mandibular right primary second molar. A 5-year-6-month-old girl was referred to our clinic for close examination of an impacted mandibular right second primary molar. An intraoral examination showed a slight pit extending inside the gingiva and on the occlusal surface of the tooth. X-ray photographic examination revealed that the affected tooth was severely submerged and had a radiolucent area on the occlusal surface, which extended close to the pulp cavity. Most of the periodontal ligament space could not be clearly identified except for the distal side of the distal root. We considered that the area of the tooth was partially ankylosed and consulted with oral surgeons, who decided to postpone extraction, due to the presence of the permanent successor close to the affected tooth. Thus, we treated the dental caries, which appeared to be technically difficult because of the deep location of the tooth. The Isolite system was utilized in this case, as we considered that adjacent soft tissue and saliva could be excluded with its use. Under infiltration anesthesia, gingival tissue covering the occlusal surface was removed with an electric knife, and the carious lesion was removed, which resulted in pulp exposure. Severe inflammation of the pulp was revealed and pulpectomy was performed. There were no signs and symptoms after the treatment. At 1 year after treatment, the occlusal surface remained exposed and no inflammatory findings were observed in adjacent gingival tissue. Key words Ankylosis, Dental caries, Isolite system, Pulpectomy, Submerged tooth.
