Impacted or unerupted permanent teeth have many problems in making a diagnosis and treatment plan in dental clinic. There are several methods to treat impacted teeth. The combination of surgical exposure and orthodontic traction is usually the treatment of choice in cases with impacted teeth. Two cases are reported, which were treated with surgical intervention and orthodontic movement. and one case is treated with orthodontic movement alone. To improve esthetic problem and maintain periodontal health, We should avoid loss of attached gingiva in surgical exposure, and excessive orthodontic force during the traction of the impacted tooth.

The purpose of this preliminary report was to describe the operating procedure of T-scan system and to identify the location, timing and force of occlusal contact in patient with normal occlusion using computerized T-scan system. From the preliminary observation , the author obtained the following results. 1. T-scan system displayed 2 dimensional and 3 dimensional description of occlusion: contact locations, timing (sequence) and forces of occlusal contacts. 2. The T-scan sensor was the most important part of the T-scan system. 3. The data of T-scan system cannot be stored in computer diskett. 4. The T-scan system is thought to be the most effective system to detect occlusal contacts and can be applied to the followings : occlusal diagnosis, occlusal equilibration, crown and bridge restorative procedures, denture adjustment, implant procedures, splint adjustment, laboratory procedures, periodontal treatment, orthodontics, TMJ treatment and patient education etc.

Osteosarcoma is a classical malignant bone-forming neoplasm which usually presents with an aggressive clinical course. The current case is presented with the radiographic feature of widening of the periodontal ligament space of the involved teeth, which is considered to be the earliest radiographic manifestation of osteosarcoma involving the jaw bone. The main aim of this case report was to focus on the importance of early diagnosis of this tumor based on clinical and radiographic examinations, and confirmation by histopathology. Considering the rarity of the disease type and particularly taking into account the fast progression and aggressiveness of this neoplasm, it is clear that the presentation of a clinical case represents a major contribution to better understanding of osteosarcomas involving the jaw bone.

The odontogenic myxoma is an infiltrative benign tumor of bone that occurs almost exclusively in the jaw bones and comprises 3% to 6% of odontogenic tumors. This neoplasm is thought to arise from the primitive mesenchymal structures of a developing tooth, including the dental follicle, dental papilla, or periodontal ligament. Radiographically the odontogenic myxoma may produce several patterns: unicystic, multilocular, pericoronal, and radiolucent-radiopaque, making the differential diagnosis difficult. In this report, two cases of the odontogenic myxoma in the jaw bones are presented. The first case involved only the mandible, while the second case involved the maxilla. Both cases presented extensive multilocular radiolucencies characteristic of odontogenic myxoma.

Purpose: The aim of augmentation of the alveolar ridge is to restore absorbed alveolar ridges for future implant site or esthetic prosthodontic restoration. The present clinical report describes the anterior maxillary augmentation cases using a soft tissue rotated palatal flap, and considers various problems of before and after surgery. Method: First & second patients were treated by vascularized interpositional periosteal-connective tissue(VIP-CT) flap for horizontal soft tissue augmentation. Especially second patient was progressed with bone grafting at the same time. Third patient was treated by the same flap with bone graft and implant placement in single tooth missing premaxillary area. Result: The obtained horizontal augmentation width measured $0.5{\sim}2.7\;mm$. Conclusion: This technique constitutes a viable approach for augmentation the anterior sector of alveolar ridge with the placement of dental implants. But it needs correct diagnosis preparation and careful surgery skill.

Purpose: These case reports show the orthodontic treatment of lower anterior incisors with gingival recession. Materials and Methods: Three cases were treated by an orthodontist and a periodontist. Each case had lingually tilted lower anterior incisors, anterior crossbite and skeletal Cl III pattern. Results: A variety of etiological factors were thought to cause gingival recession: aging, oral hygiene, tooth malpositioning, occlusal trauma. Conclusion: Due to the interaction among many possible contributing factors, it is difficult to predict whether further gingival recession may occur at a given site. The position and the movement of the lower anterior incisors with gingival recession are important factors in diagnosis and orthodontic treatment planning.

Fusion and gemination are developmental anomalies of teeth that may require endodontic treatment. Fusion may cause various clinical problems related to esthetics, tooth spacing, and other periodontal complications. Additional diagnostic tools are required for the diagnosis and the treatment planning of fused tooth. The present case report describes a case of unilateral fusion of a supernumerary root to an upper permanent central incisor with large periapical lesion in which a conservative approach was used without extraction of supernumerary tooth and obturated with mineral trioxide aggregate to reach a favorable outcome.

Toothache is one of the most common discomforts experienced by patients in dental clinic. If clinical and radiographic examinations do not reveal any pathologic findings, we can suspect nonodontogenic toothache. Nonodontogenic toothache can be caused by a variety of causes such as muscle disorders, sinus and nasal mucosal problems, neuropathic pain, neurovascular pain, psychogenic problems, and cardiogenic disease. A thorough history and clinical examination should be performed to confirm the cause of the pain, and more accurate diagnosis can be established through local anesthetic injection. If the nonodontogenic toothache is misdiagnosed, unnecessary dental treatment such as root canal treatment, periodontal treatment, and extraction can be performed, and the patient's pain is not alleviated through such treatment. Therefore, the cause of toothache must be diagnosed correctly before dental treatment is performed, and clinicians should be fully aware of the diseases that may cause these symptoms.

Vascular calcification is the heterotopic accumulation of calcium phosphate salts in the vascular tissue and is highly correlated with increased cardiovascular morbidity and mortality. In this study, we found that the expression of neuromedin B (NMB) and NMB receptor is upregulated in phosphate-induced calcification of vascular smooth muscle cells (VSMCs). Silencing of NMB or treatment with NMB receptor antagonist, PD168368, inhibited the phosphate-induced osteogenic differentiation of VSMCs by inhibiting Wnt/β-catenin signaling and VSMC apoptosis. PD168368 also attenuated the arterial calcification in cultured aortic rings and in a rat model of chronic kidney disease. The results of this study suggest that NMB-NMB receptor axis may have potential therapeutic value in the diagnosis and treatment of vascular calcification.

Orofacial pain has various causes, making it challenging to differentiate from dental-related diseases based solely on symptoms. Toothache, usually attributed to pathological changes in the pulp and periodontal tissue, is the most common cause of orofacial pain and relatively easy to diagnose. However, distinguishing orofacial pain and nonodontogenic toothache due to myofascial, neuropathic, neurovascular, paranasal sinus and cardiac originating, and psychogenic pain presents diagnostic challenges that may result in incorrect treatment. Therefore, dentists must recognize that orofacial pain can arise from not only dental issues but also other causes. This case report explores the necessary considerations in diagnosing orofacial pain and nonodontogenic toothache by examining the diagnoses of patients presenting at the dental hospital with orofacial pain and nonodontogenic toothache of cardiac origin.
