A Radicular Cyst in the Mandibular Anterior Region of Primary Teeth.

Radicular cysts are common among odontogenic cysts but are rare in primary teeth. They occur more frequently in the mandibular molar region and rarely in the mandibular anterior region. This is a case of a radicular cyst in the mandibular anterior teeth during the primary dentition stage. In addition, after the fenestration of cystic lesions, gauze is generally changed to prevent the extraction socket from closing. However, in this case, the patient was six years old. Therefore, to alleviate the burden of changing the dressing gauze, we practiced putting on and taking off the obturator before fenestration and using it immediately after surgery under general anesthesia. This made it possible to change the dressing gauze after surgery. We were able to maintain an open wound without the burden of dressing gauze changes. The use of the device was shown to be effective in maintaining open wounds in young patients.
