“…The objectives of jaw cyst resection are to terminate the pathological process, promote the restoration of jaw bone tissue, and restore the anatomical and physiological functions of the teeth in the cyst area [15,16] . According to traditional surgical methods, root canal therapy and apical resection should be adopted as long as the tooth can be retained, regardless of the pulp activities in the cystic area [4,5] .…”

Background: Jaw cyst is the most common disease of the oral and maxillofacial region. In addition to the pathogenic tooth, the roots of some teeth are often located in the cavity of the cystic capsule. Whether these involved teeth require root canal therapy and apicoectomy is still inconclusive. In the present study, we aimed to preserve the pulp activity of involved teeth in jaw cyst by improved operation.Methods: In our improved surgical method, the root canal therapy was not performed on the involved teeth, and no apical excision was performed during the operation. 63 involved teeth in 20 cases of jaw cyst treated by our department were selected between September 2015 and October 2017. The involved teeth were diagnosed by X-ray, CBCT, and a pulp vitality test before surgery. We observed the pulps' activity in the involved teeth and the efficacy of surgery for 12-36 months.Results: Electrical activity test of 63 involved teeth pulp in 20 patients with jaw cyst was normal or insensitively before operation. The involved teeth were preserved by improved surgical method. After 12-36 months’ follow-up, the pulp activity of 53 involved teeth (84.1%) were preserved, whereas 10 teeth (15.9%) showed adverse symptoms such as redness and swelling in the apical area, fistula, and pain. These symptoms resolved after postoperative root canal therapy. Chewing function was restored well. There was no recurrence and the bone cavity gradually reduced and finally disappeared, and bone density returned to normal after long term follow-up.Conclusion: Our results showed that to preserve the activity of the involved teeth for the treatment of jaw cyst by performing an improved operation method was effective.

“…It was assessed by Visual Analogue Scale (VAS) [14] . For each patient, pain was recorded as follows: mild pain (VAS, 1-2) was 16 patients (80%), and moderate pain (VAS,3-4) was four patients (20%), heavy pain (VAS, 5-6) was 0 patients (0%) [15] .…”

“…But it was reported that dentigerous cysts associated with supernumerary teeth are rare. Moreover, in younger children, the report of the dentigerous cyst associated with supernumerary teeth is fewer [1][2][3][4][5] . In these cases, dentigerous cysts should be removed or be marsupialized for treatment.…”

This report presents a case of eruption guidance for an upper right central incisor with a dentigerous cyst associated with an impacted supernumerary tooth in a 5-year-9-month-old boy. A swelling was seen in the region of an upper right central incisor. Radiographic examinations showed that a well-defined cystic lesion, containing an impacted supernumerary tooth crown in it, was located between the root of the primary upper right central incisor and a permanent upper central incisor germ. Under general anesthesia, the dentigerous cyst was removed at extraction of the upper impacted supernumerary tooth. And then, a socket was kept open wound. A histopathological examination confirmed the diagnosis of a dentigerous cyst associated with a supernumerary tooth. By using an obturator, we guided eruption of an upper right central incisor with malposition that was caused by the dentigerous cyst, and observed the way of the tooth eruption for two years and seven months. The obturator was inserted in the socket directly for three months until it was closed. After that, the obturator was used as only a removable space maintainer. Eight months after the operation, the obturator was removed because the upper left central incisor began to erupt. Two years and seven months after the operation, both upper central and lateral incisors had erupted completely. In this case, the obturator was used for expectation of natural eruption of permanent incisors, space maintenance and aesthetic recovery. The permanent incisors had been able to be guided to almost correct position without traction. some difficulties to do those treatments in pediatric dentistry, because some patients are uncooperative for earlier age, or some patients in mixed dentition period needing eruption guidance. Nevertheless it is necessary to treat correctly with those cases in order to develop the normal permanent dentition. In this case, we treated a 5-year-9-month-old boy with a dentigerous cyst caused by an impacted supernumerary tooth. The dentigerous cyst was removed at extraction of the upper impacted supernumerary tooth, and the socket was kept open wound. By using the obturator, we guided eruption of the upper right central incisor with malposition caused by dentigerous cyst. And then we observed for two years and seven months.

“…Only one case reported the use of nitrous oxide with general and local anaesthesia [96]. Some of the included clinical studies did not mention the type of anaesthetic technique used [10,14,16,17,21,35,36,39,42,44,46,49,50,51,54,55,57,59,66,68,70,74,78,79,81,82,85,89,90,93,98,102,103]. In one study the extracted tooth was re-planted after the marsupialization, however there was no enough long term follow-up [16].…”
