The purpose of this report was to evaluate the effect of Dental Electronic Anesthesia on pain inhibition for clinical use. The subject for this study were 30 children whose Frankl behavioral rate is positive. The subjects was divided into two groups, the first group described by control group and the second group described by experimental group anesthetized with Dental Electronic Anesthetic device. And then three kind of treatments were done : extraction of deciduous teeth, application of rubber dam, cavity preparation for preventive resin restoration. 3M Dental Electronic Anesthesia System was used for this study : its electric impulse stimulate the skin surface by external electrode pads. The results were as follows. 1. Degree of the pain & the apprehension decreased in experimental group. 2. Degree of the pain & the apprehension showed statistical differences among three treatments procedures in the control group but, not showed statistical differences in the experimental group.

11 years 7 months old female had a reverse object of anterior teeth and class III molar relationship. Maxillary right and left canines were erupted labially and lower left lateral incisor was congenitally missed. She was treated by rapid palatal expansion and full band technique with extraction of maxillary and mandibular second molars. The following results were obtained. 1. Maxilary arch was expanded. 2. Anterior cross-bite and crowding was corrected. 3. Molar relationship was corrected. 4. Profile was somewhat improved.

After extraction of tooth, alveolar ridge resorption is inevitable in most cases. Clinicians confront with horizontal and vertical resorption of alveolar bone. Without massive amount of bone and soft tissue graft, dental implant will be placed apically to gain stability. In those cases, not only white esthetic part, but also pink esthetic part should be restored with pink porcelain. The margin of prosthesis should be located apically to reproduce natural look with adjacent teeth. However, when the margin is located apically, it is always hard to remove remaining cement, thus complications may arise. In this report, a novel design of implant prosthesis is introduced to solve those issues. The novel design is consisted of zirconia framework with pink porcelain and separate crowns on top of the framework. It eliminates the possibility of cement remnants by bringing the crown margin coronally. Pink esthetic part is incorporated in abutment part instead of crown part and the screw hole is covered with separate crowns.

In spite of appropriate treatment of peri-implantitis, the peri-implant bone loss was keep going, the clinician should remove the osseointegrated implant. the conventional methods are like a extraction of natural teeth, and use of trephine drills. In these days, many exclusive instruments are invented by implant companies. these instruments can make easy, least invasive, less traumatic removal of osseointegrated implants. In generally peri-implant bone loss progress steadily less sign and symptoms that the patient do not want to remove their implants. However, the failure of dental implant is big burden to clinicians and also patients. In the dental implant treatment, there is no 'failure' but only is 'replacement' or 'change'.

Pain control by means of local anesthesia is an intrinsic part of clinical practice in dentistry. Several studies evaluated intraligamental anesthesia using a computer-controlled anesthetic device in children. There is a need to provide a clinical guide for the use of computerized intraligamental anesthesia in children. Intraligamental anesthesia using a computer-controlled anesthetic device was found to cause significantly lower pain perception scores and lower pain-related behavior than traditional techniques. This device proven to be effective in restorative and pulp treatment in children; however, its effectiveness in primary teeth extraction is controversial. It is important to withdraw recommendations necessity of future studies concerning the side effects of computerized intraligamental anesthesia in children. The present study aims to review different clinical aspects of computerized intraligamental anesthesia in children along with the side-effects, type of local anesthesia and postoperative pain of this technique. This study provides dentists with a clinical guide for the use of computerized intraligamental anesthesia.

Cleidocranial dysplasia is an autosomal dominant heritable skeletal disorder. The characteristic features of cleidocranial dysplasia (CCD) may include hypoplasia of the clavicle, delayed closure of frontanelles, late tooth eruption, and other skeletal disorders. This case report describes clinical and radiographic manifestations at the age of 11 and 29 of a CCD patient, investigates the mutation of core-binding factor A1 (CBFA1) based on gene analysis, and illustrates successful oral reconstruction with fixed prosthesis and dental implant after the extraction of multiple teeth.

Radicular cyst is the most common odontogenic cyst occurring in the jaws. The cyst is commonly found in relation to the maxillary anterior teeth in the third and fifth decade of life. Although multiple radicular cysts are not uncommon in the jaws, bilaterally symmetrical representation of these cysts is rare. Radiographs prior to extraction help in diagnosis of these cysts and thereby prevent further morbidities. We report a case of 16-year-old male patient who presented bilateral radicular cysts symmetrically in the mandible.

Even the adult cleft lip and palate patient who has not had timely treatment during the growth period, can be treated with orthodontic treatment without the necessity of orthognathic surgery if only the patient is treated under correct diagnosis and fitting appliances. Initially, maxillary arch form is established by constructing trifocal circles. Posterior region can be expanded and derotated laterally with pentahelix and anterior teeth are aligned with Tiggle brackets and "ㄷ"-shaped spring. Thereafter, anterior and posterior regions are consolidated. Mandibular intercanine width should be adjusted to maxillary intercanine width which was unavoidably reduced. Mandibular anterior tooth extraction will be helpful to attain proper mandibular intercanine width and better anterior dental showing.

A 8-year-old patient presented with a crown-root fracture of the maxillary right central incisor with an oblique subgingival fracture line. A multidisciplinary treatment approach including endodontic treatment, surgical extraction and intraalveolar repositioning was used to gain sufficient crown length of the fractured maxillary incisor. The coronally repositioned maxillary right central incisor was stabilized by a resin wire splint. Apexification using MTA was performed. Resin core and direct resin restoration(Cl IV) on fractured teeth was built up. Clinical and radiographic follow-up of the maxillary right central incisor after 36 months showed no signs of root resorption or pathology and acceptable aesthetics and functions were maintained. Surgical extrusion can be considered as a good treatment modality for young patients.

Overlay complete dentures are simple, reversible and economical treatment modality for patients with congenital or acquired disorders that severely affect the tooth development. It satisfies both the esthetic and functional demands where the extraction of teeth is not generally indicated. In pediatric patients, the overlay dentures establish a relatively stable occlusion that improves patient's tolerance to the future treatment procedures for worn dentition. This clinical report highlights the imperative need of appropriate treatment strategy and application of maxillary and mandibular overlay dentures in a pediatric patient who suffered from congenitally mutilated and worn dentition.
