Abstract

Treatment of odontogenic cyst in pediatric patients should be considered to preserve adjacent anatomical structures, especially developing permanent teeth. Decompression can prevent damage to surrounding permanent teeth and induce spontaneous eruption of permanent teeth. Removable space maintainer with rubber tube for decompression is used to maintain the patency of the cyst and space for the eruption. These are four case reports of odontogenic cyst involving maxillary canine and mandibular premolars. Due to preserving permanent teeth, all cases were treated with decompression. This case report shows that mandibular premolar spontaneously erupted into the proper position. While maxillary canine may need additional treatment intervention, such as orthodontic traction or surgical extraction.
