Abstract

|
Dentigerous cyst is the most common developmental odontogenic cyst of the jaw which is associated with unerupted teeth. Treatment modalities range from enucleation to marsupialization. Enucleation is the process in which the cyst is completely removed, and this is usually indicated for smaller lesions. Larger cysts can be treated by marsupialization, which is a process that consists of making a surgical cavity on the wall of the cyst, emptying its content and maintaining the continuity between the cyst and the oral cavity. This procedure allows decompression of the cyst, regeneration of the bone-defected area, and also lets the wall of the cyst change into normal mucosa. This technique will protect adjacent structures and will promote spontaneous eruption of succedaneous teeth previously surrounded by the cyst. These are two case reports of a 5-year-old and an 11-year-old boy with dentigerous cysts found regarding supernumerary tooth and pulpotomized mandibular primary molars, respectively. Due to the large size of the cysts, both cases were treated with marsupialization. This case report shows that in cases regarding large-sized dentigerous cysts, marsupialization can be an effective surgical technique that promotes spontaneous eruption of cyst-involved succedaneous teeth and the preservation of adjacent teeth.
