ABSTRACT

Dentigerous cyst is the most common developmental odontogenic cyst of the jaw which is associated withunerupted teeth. Treatment modalities range from enucleation to marsupialization. Enucleation is the process inwhich the cyst is completely removed, and this is usually indicated for smaller lesions. Larger cysts can be treatedby marsupialization, which is a process that consists of making a surgical cavity on the wall of the cyst, emptyingits content and maintaining the continuity between the cyst and the oral cavity. This procedure allowsdecompression of the cyst, regeneration of the bone-defected area, and also lets the wall of the cyst change intonormal mucosa. This technique will protect adjacent structures and will promote spontaneous eruption ofsuccedaneous 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 regardingsupernumerary tooth and pulpotomized mandibular primary molars, respectively. Due to the large size of thecysts, both cases were treated with marsupialization. This case report shows that in cases regarding large-sized dentigerous cysts, marsupialization can be aneffective surgical technique that promotes spontaneous eruption of cyst-involved succedaneous teeth and thepreservation of adjacent teeth.
