Recently computer-aided technology has been widely used in dentistry. DENTCA™ CAD/CAM denture system (DENTCA Inc.), one of CAD/CAM systems for fabricating complete denture, tries to collect and store all of a patient's information at the first visit. This system aims to deliver denture at the second visit through utilizing the CAD/CAM software to access the stored data for designing the 3D denture model. The 3 dimensional (3D) denture will then be fabricated with 3D printer. Many case reports have evaluated clinical application of CAD/CAM system for fabricating complete dentures. This case report is about fabricating of complete dentures using DENTCA system and conventional method in same patient. With two cases, usefulness and limitation of DENTCA system could be evaluated.

Patients who get tooth loss would also lost their esthetic, stability and functional aspect suddenly. They have to get provisional restoration immediately. This case reports a satisfied result that thermoforming technique is good for patients to get injury from unexpected tooth loss.

Malignant lymphomas are neoplasms with diffuse proliferation of neoplastic lymphocytes and their precursor cells. Diffuse large B-cell lymphoma, which is a subtype of non-Hodgkin's lymphomas, rarely occurs in the head and neck area and is especially rare in the maxillary sinus. We report a case of a 76-year-old female patient who was referred to the oral and maxillofacial surgery office for evaluation of a dental abscess as a clinical diagnosis. Laboratory tests revealed no signs of inflammation or infection; therefore, incisional biopsy was performed. The final diagnosis was diffuse large B-cell lymphoma in the maxillary sinus. Here we describe this case with a review of relevant literature.

Whereas a somatic pain notifies tissue damage, a neuropathic pain presents disorder of the nerve itself. The causes of neuropathic pains are trauma, infection, chronic irritation by adjacent tissue and so on. The iatrogenic trauma or infection also causes traumatic neuropathy, which may exert a bad influence on doctor-patient relationship. Some of related dental treatments are implantation (directly or indirectly through heating), root canal treatment, teeth extraction, block anesthesia, mandibular surgery. If inappropriate management is performed after nerve trauma, there will be many chances to develop chronic neuropathy for the patient. It is important that the sign of nerve trauma have to be caught by the practitioner as soon as possible and treated properly.

PURPOSE: Gingival whitening is one of dental treatment purposes which is close to treating aesthetic disorders. Initial gingival whitening treatment was done by dermabrasion using a high power Diode Laser. However, this treatment method cannot be free from any infection or pain after the treatment. Therefore, we have decided to progress gingival whitening treatment using a low power LED laser. MATERIALS AND METHODS: The laser was irradiated on pork meat then the safety of output power, temperature change and skin denaturalization was measured. Bison 365 nm LED laser was irradiated on oral mucosal pigment of a 15 - 20 kg beagle for 15 min for 1 - 2 weeks, one or two times each. Any pigment loss was checked through Hematoxyline-Eosin staining. RESULTS: The melanin pigments at the area of 365 nm LED Laser irradiation were decreased. CONCLUSION: The 365 nm LED Laser proposed in this study is considered to compensate the bleaching effect achieved by either using Diode laser or surgical methods.

PURPOSE: The aim of this study was to evaluate correlations between denture satisfaction and various factors related to patients' and wearing dentures. MATERIALS AND METHODS: Total 43 edentulous patients were recalled and they were wearing complete dentures fabricated more than one year ago. For patients' subjective assessment, the questionnaire based on the various literatures was developed and applied to patients for data acquisition. In addition, correlations were evaluated between subjective assessment and denture satisfaction score. For statistical analysis, Spearman correlation coefficient, multiple regression analysis, Mann-whitney U test and Kruskal-Wallis test were used to found out what the most considerable factors to denture satisfaction score (P < 0.05). RESULTS: Denture satisfaction score of maxilla was higher than mandible (P < 0.05). In functional aspects, maxillary denture were received a favorable evaluation. Especially fit and pain causing were highly correlated to satisfaction. Gender, age, using period, visiting times after manufacturing denture were unrelated to satisfaction. But previous experience was related to denture satisfaction. CONCLUSION: Denture satisfaction was determined by a combination of various factors related to patients.

Headache disorders, one of most common disease in general population, have been developed according to many versions of international classifications. The primary headaches are those in which no consistently identified organic cause can be determined. It is divided into the following categories: (1) migraine, (2) tension-type headache, (3) cluster headache and other trigeminal autonomic cephalalgias, (4) other primary headaches. This review described a diagnosis of primary headache disorders based on International Classification of Headache Disorders (ICHD)-3 beta criteria.

The average life expectancy has been increased, so the proportion of elderly patients that visit to the dental clinic for prosthetic restoration has increased. Elderly patients have various chronic diseases. Recent trends show an increase of osteoporosis in elderly patients, and thus, the number of osteoporosis patients is expected to escalate. Currently, the most widely used drug for osteoporosis is bisphosphonate. However, osteonecrosis of the jaw has been reported as a side effect derived from long-term oral administration or injection treatment of the drug. Surgical dental treatment was the main cause of medication related osteonecrosis of the jaw (MRONJ). As MRONJ is very difficult to cure, it is important to take preventive measures. Surgical operation may be needed for the mouth preparation before prosthetic restoration. For successful treatment, the dentist should have a full understanding of osteoporosis and show a continued interest toward this disease for careful management.

Conventional removable partial dentures (RPDs) with distal extensions are associated with some problems, including lack of stability that calls for frequent relining, and cantilever actions of claps that can produce excessive loading to abutment teeth, and the need for unesthetic retentive arm clasps. Therefore, IARPDs (Implant-assisted RPD) that use implants to support or retain RPDs has been reported to improve stability, esthetics and masticatory performance of RPDs. Also, an IARPD that has zirconia occlusal table can prevent the incongruity of occlusal plane and the extrusion of antagonistic tooth. In this case of partially edentulous patient with crossed occlusion, each edentulous area was restored with implant fixed prosthesis and implant retained partial denture to suit each situation. Through the procedure, satisfactory outcomes were achieved both in functional and esthetic aspects.

Overdenture is one of the methods of patients with severely worn dentition. Remaining natural teeth help preserve alveolar bone and proprioception and provide rigid support. Also, overdenture distributes the concentrated stress applied to the abutment tooth and denture supporting tissues. There is an advantage that it can provide long-term stability to denture. In this case, the patient with only a few teeth due to severe wear and caries was satisfied with good function and favorable esthetics by using overdenture.
