The aim of the present study was to examine the effect of low power generating semiconductor laser on healing process after surgical procedure. Use of DENS-BIO Laser(Dong-Yang medical) treat the surgical site every 4min after surgical procedure. Chidren was to treat mesiodens extraction, frectomy. And they are examined surgical site every day and healing process was observed. The result form the present study can be summarized as follows : 1. The Healing process is more faster then no radiation group. 2. Pain is less then no radiation group.

Maxillary overgrowth who diagnosis with skeletal classⅡ division. I have transverse and also sagittal problem. It maxillary growth vector is direction to anterior-inferior, mandible is rotation to clockwise pattern and it disturbance of anterior growth. At this time, treatment goal is restrict of maxillary growth to accomplish ideal intermaxillary relation and one of treatment choice is the application of extraoral force. This report is 3 case treated by activator and headgear combination therapy, who diagnosed with skeletal classⅡ div. 1 malocclusion and following results were observed: 1. For ward and downward growth of the maxillary complex were inhibited. 2. Mandibular growth was stimulated and counterclockwise rotation of the mandible was observed. 3. Large overjet and deep overbite were corrected.

The odontomas are most common benign odontogentic tumors composed of various tooth -like structures with enamel, dentin, cementurm and pulp tissue. It's etiology is unknown, but it has been suggested that local trauma or infection may lead to the introduction of such a lesion. WHO classification divides 2 group such as complex composite odontoma and compound composite odontoma, that clacified dental tissues are simply an irregular mass bearing no morphologic similarity even to redimentary teeth. Odontomas are usually asymptomatic and are discovered on routine dental radiographs. But it become swelling, impacted teeth, delary eruption of teeth. Odontomas are usually asymptomatic and are discovered on routine dental radiographs. But it become swelling, impacted teeth, delary eruption of teeth. Surgical extraction is best choice, that procedure is no side-effect and no expectancy of recurrence of complications after removal. In our this case, 2 patients with odontoma who visited Dept. of Pediatric Dentistry in Chosun Dental college. Were treated by means of surgical removal, and progress was good.
