Ameloblastomaa are odontogenic benign tumors with epithelial origin, which are characterized by slow, aggressive, and invasive growth. Most ameloblastomas occur in the mandible, and their prevalence in the maxilla is low. A 27-year-old male visited our clinic with a chief complaint of the left side nasal airway obstruction. Three-dimensional computed tomography showed left maxillary sinus filled with a mass. Except for the perforated maxillary left edentulous area, no invaded or destructed bone was noted. The tumor was excised via Le Fort I osteotomy. The main mass was then sent for biopsy and it revealed acanthomatous ameloblastoma. The lesion in the left maxillary sinus reached the ethmoidal sinus through the nasal cavity but did not invade the orbit and skull base. The tumor was accessed through a Le Fort I downfracture in consideration of the growth pattern and range of invasion. The operation site healed without aesthetic appearances and functional impairments. However, further long-term clinical observation is necessary in the future for the recurrence of ameloblastoma. Conservative surgical treatment could be the first choice considering fast recovery after surgery and the patient's life quality.

Temporomandibular disorders typically present findings of limited or asymmetric patterns of jaw opening and joint sounds usually described as clicking, popping, grating, or crepitus. Recently, patients with temporomandibular disorders have received an increasingly aggressive treatment with a greater emphasis on surgical and dental reconstruction. Scientific studies have not clearly identified the specific causes of the temporomandibular disorders and therefore some of the treatments are empiric, without a firm scientific foundation. We carried out a study on the patients of pain clinic OPD and concluded that the causes of the temporomandibular joint(TMJ) pain are the prolonged contraction of the muscles of mastication, especially the masseter muscle. Therefore, the spasmolytic treatment of masseter muscle would be a better treatment for TMJ syndrome rather than the surgical and dental reconstruction.

Purpose: In this study, we evaluate the potential of the relative ratio of capsular width (RCW) between the affected side (Aff) and non-affected side (Non-aff) in patients with temporomandibular joint (TMJ) arthralgia. We assessed whether RCW may hold greater diagnostic significance than the objective capsular width (CW) reported in previous studies when diagnosing arthralgia using ultrasonography (US). Methods: Forty-nine patients were assessed using US, excluding four patients with bilateral arthralgia. The patients were divided into two groups: 40 with unilateral arthralgia (UA), and nine without arthralgia (NA). We measured CW and masseter muscle thickness using US. Moreover, we employed RCW to analyze the variances between the groups. The numerical rating scale (NRS) and RCW were compared before and after dexamethasone injection in 10 patients who underwent follow-up evaluations. Results: Within the UA group, CW on the Aff was found to be significantly larger compared to the Non-aff (p<0.001). Additionally, RCW in the UA group was greater than that in the NA group (p<0.01). Furthermore, after dexamethasone injection, a reduction in the NRS and RCW values was observed in the 10 patients who were followed up. Conclusions: While previous studies have suggested a link between arthralgia and TMJ effusion, making CW a possible indirect diagnostic indicator for arthralgia, our findings propose that RCW could hold more diagnostic value than objective CW. However, additional studies are required to standardize the protocols for interpreting US results and determining the cutoff value of RCW in diagnosing TMJ arthralgia.

In most persons with disabilities had poor oral hygiene because of less attention and ability to perform a dental care. So the increased prevalence and severity of dental disease were common oral state. Although most persons with disabilities need a adequate dental treatment, it is often very difficult to treat because of noncooperativity and involuntary muscle movements. Dental treatments under sedation and general anesthesia were make to provide a high-quality dental service because of decreased anxiety and fear associated dental treatment in persons with disabilities. The dental professionals must be able to select and apply the proper sedation methods in agreement with the characteristics of the disabilities, general conditions, sedation experience and capacity of dentist, type and time of dental treatment, equipments of dental clinic, consent of patient's protector. The proshodontic treatment procedures, such as abutment preparation, dental impression taking process, try-in process of prosthesis and adjustment of occlusion, are difficult even for patients without disabilities. Those procedures are more difficult to patients with disability because it's too hard to control breathing and muscle. In this report, we performed prosthetic dentistry procedures to three patients with disabilities under dental sedation and general anesthesia.

In chronic temporomandibular disorders (TMDs), constituent tissues such as muscles are sensitive to pain and psychological stress, which negatively affect the quality of life. In addition, since chronic TMDs is often accompanied by diseases such as psychological disorders and other chronic pain disorders, the diagnosis of those diseases and patient referrals are mandatory. The management of chronic pain in TMDs requires a multidisciplinary and holistic approach. Pharmacological therapy using cyclobenzaprine, serotonin and norepinephrine reuptake inhibitors, tricyclic antidepressants, progressive relaxation, and psychological approaches using cognitive behavioral therapy such as shifting negative thoughts about pain are all valid treatment options.

Objectives : The purpose of this study was to understand how work environment and conflict level of dental hygienists affect turnover for the efficive manpower management of dental hygienists. Methods : Dental hygienists in dental (hospital)clinics near Daegu were randomly selected as the subjects of this study, and the followings analysis results are from 249 questionnaires: which were collected from March 2 to March 31 2011. Results : Among the 249 dental hygienists surveyed, 33.7% experienced turnover and 59.0% had turnover intention. From the analysis of the demographic, working environment and levels of conflict, dental hygienists had significantly higher turnover experiences based on following factors: older age, employment at a dental clinic rather than a dental hospital, longer working hours, longer total career as a dental hygienist, and longer of length of time at their current job. Furthermore, dental hygienists had significantly higher turnover intentions based on the following factors: younger age, more ignorant and higher level of discomfort due to conflict levels. Conclusions : Therefore, the working environment of dental hygienists has to be improved to inspire motivation, and conflict management has to be taughht within an organization to allow free communication and active participation in decision-making.

The purpose of this study is to discuss the economic outlook of dentistry in relation to pessimistic economic perspectives of Korea and to present subsequent solutions. The expectation of the future economic growth rate of Korea is gloom with not only a love rate of increase in population due to an aging society and a low birthrate, but also with a declined number of productive populations. Moreover, the future of dentistry in Korea is obscure. Even with a dwindling population growth, an average of 750 new dentists graduate from dental school every year. The 30-35% of the new graduates practice in public hospitals; and 65~70% of them open up their own private practices, However, unlike in the past, the occurrence of dental practice bankruptcy has been increasing with a competitive environment, excessive initial investment, knowledgeable patients, and etc. Therefore, it is essential to re-evaluate the number of new graduates. Also, it is necessary to supply a greater number of public hospitals with newly licensed dentists, who have various clinic experience, participate in research and development, and experience appropriate hospital management skills.

Multiple myeloma is malignant neoplasm of plasma cells. Mandible lesions are rarely the first symptoms of multiple myeloma. While sensory dysfunction and pain are the main symptoms of traumatic trigeminal neuropathy, the same oral symptoms can appear in cases of multiple myeloma with developed mandible lesions. In addition, if the radiological osteoporosis or lytic lesion is seen in older patients, further examination is required to find the cause of the symptoms. In this paper, we present a case that was tentatively diagnosed as traumatic trigeminal neuropathy after left third molar extraction, but later confirmed as multiple myeloma.
