In children, they were presented pain and discomfort after surgical procedure. Some study has been suggested that Soft Laser promote healing process. So, the aim of the present study was to examine the effect of low power generating semiconductor laser on healing process after surgical procedure. DENS-BIO Laser applied to the wounds created by mesiodens extraction and lingual frenectomy. DENS-BIO Laser was irradiated on the wound with pulse 8(1000Hz) and 2mW, for 4 minutes. And then, healing process of surgical site was observed. The results from the present study can be summarized as follows : 1. In the irradiated wound, the healing process is more faster than not irradiation group. 2. Pain is less than not irradiation group.

Cone beam computed tomography (CBCT) has become widely available in recent years and is recognized as an important diagnostic tool for varies disease and condition of the orofacial structure. Clinician is easy to determine adequate treatment plan for pediatric patients by using CBCT. CBCT is used in Chonbuk National University Dental Hospital since 2005. This research presents clinical application of CBCT on patients visiting department of pediatric dentistry in Chonbuk National University Dental Hospital from Jan, 2005 to July, 2011. 1. Total number of patients taken CBCT is 252, and total number of area taken CBCT is 279. 2. An age group form 9 years to 12 years showing 53% was highest and percentage of 6~8 years showed 24%. 3. Chief complaints for CBCT taking are position and shape of impacted teeth (49.1%), mesiodens (19.4%), supernumerary teeth (7.9%), position and root canal shape of erupting teeth (7.2%), cyst (5.4%), inflammatory lesion (3.9%), odontoma (3.9%), tumor (2.2%), and et al. 4. Treatments are extraction (29.7%), orthodontic traction and leveling (24.0%), follow up (16.5%), refer to other professional part (11.5%), endodontic treatment (3.9%), surgical removal (2.9%), malsupialization (3.9%), enucleation (1.1%), and fail to follow up (5.0%), and et al.

The optimal time for the removal of supernumerary teeth can be divided into two groups; early removal and late removal. While each group has its own advantages, the effects on maxillary central incisor can be significant. The purpose of this study was to determine the ideal time for the removal of the supernumerary teeth by evaluating 166 patients for three months after surgical removal of supernumerary teeth. Relatively young patients in early Hellman's dental stage with less developed or unerupted maxillary central incisor had less midline deviation. No statistical significance was found in diastema, rotation of the maxillary incisors and their changes during a follow-up period. Removal of supernumerary teeth should be considered as a preventative measure prior to eruption of the maxillary incisors when the midline deviation is observed in panoramic radiographic examination. This study will be useful in determining the optimal time for the removal of supernumerary teeth depending on the location of the maxillary incisors. This study will be informative on deciding the optimal time to remove the supernumerary teeth depending on the various positions of the maxillary central incisor. (this sentence is better to use)

Supernumerary tooth was resulted from excessive proliferation of dental lamina and associated with familial tendency and a congenital syndrome such as Cleidocranial dysostosis or Gardner's syndrome. Incidence reports identify a range of $0.3{\sim}0.8%$ in primary dentition, $1.0{\sim}3.5%$ in permanent dentition with males being affected twice as frequently as females, maxilla nine times as frequently as mandible. The most common supernumerary tooth is the mesiodens, which located between the maxillary central incisors, and the next common site is the fourth molar and lateral incisors. Supernumerary teeth are uncommon in the mandible, but premolars are the most common supernumerary teeth and occurrence is very rare in the incisor region of the mandible and the incidence is 2%. We need a early diagnosis and appropriate treatment plan because of possiblilty of diastema and eruption failure displacement, rotation of the associated permanent teeth, root resorption and dentigerous cyst with presence of the supernumerary teeth. In this two case, one supernumerary tooth located in the mandibular incisor region, the other supernumerary tooth located in premolar region. We could get normal alignment of mandibular dentition by extraction and orthodontic treatment.
