Dentigerous cysts are common odontogenic cysts of the jaw associated with an unerupted tooth. However, even if a dentigerous cyst is diagnosed, histopathological diagnosis occasionally shows odontogenic tumor. We examined 15 cases diagnosed as dentigerous cyst, showing a radiolucent area in the jaw. One of the treatment choices is cyst removal with open wound or marsupialization that promotes new bone by reducing the intracystic pressure. However, the marsupialization hole gradually reduces leaving a cyst cavity, which often becomes infected due to food impaction, leading to pain and discomfort. We present a novel technique employing an easy-to-use wire obturator for patients with dentigerous cysts.
This study analyzed and clinically evaluated demographic data, lesion site, treatment method, postoperative course, etc. of 15 patients with dentigerous cysts treated with a wire obturator. The wire obturators were maintained for 2-9 months and irrigated once every 4-8 weeks in the outpatient clinic to prevent closure of the marsupialization hole. After marsupialization, the patients were taught how to carry out appropriate oral hygiene procedures including instructions on brushing and daily rinsing, allowing them to clean the cystic cavity and follow good oral hygiene procedures by themselves at home. We radiographically evaluated their bone healing in all cases without pain, discomfort and infection. These results suggest that this wire obturator provides an effective technique for the treatment of dentigerous cysts.
