Recently, researches to develop phased array ultrasonic examination techniques are proceeded to diagnose dental caries and the status of surgical operation of dental implant. Sound field analysis of phased array ultrasonic transducers were carried out in order to characterizing the ultrasonic phased array beams. The sound field of ultrasonic radiation was calculated for the sample called "gypsum-improved stone" with the similar characteristics of dental materials. Industrial phased array ultrasonic devices were utilized for the insptriion of the artificial flaws machined in the gypsum-improved stone. Dental implants were made at the pig jaw bone and defect images were confirmed for the dental implants.

Rhinoliths are foreign bodies composed of mineralised deposits in the nasal cavity that are rarely encountered in routine dental practice. The current report presents a case of a 77-year-old female patient who visited a dental treatment centre for a routine dental check-up and prophylaxis. On the clinical examination, the patient did not report any breathing difficulty, nasal obstruction, or any form of discharge. Panoramic radiography showed a horizontally magnified radiopaque structure in the right nasal fossa region. Cone-beam computed tomography (CBCT) revealed a hyperdense entity with a laminated presentation in the right nasal fossa. The hyperdense entity was diagnosed as a rhinolith based on the radiographic findings. Although the patient was asymptomatic, a referral was made to an ear, nose, and throat surgeon for a further evaluation. This report highlights the importance of CBCT imaging in the diagnosis of soft-tissue calcifications.

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.

Objectives : The aim of the study is to offer basic data that help to reduce dental fear by measuring adult dental fear level with DFS scale. Methods : The subjects were 300 persons including college students in W University and their parents in Jeollabuk-do Province. Data were collected by convenience sampling from May 1 to May 30, 2013. Results : 1. Dental clinic visit provoked pain in 99 people(47.4%). Oral examination and preventive treatment evoked pain in 13 people(6.2%). 2. Women tended to feel much pain than men. Both women and men felt the thrilling fear when a needle pricks the flesh. 3. Respondents having dental caries, gum bleeding, halitosis, shaking tooth, and painful tooth had a higher dental fear level. 4. The direct pain experience(p<0.001) had the greatest influence. The next influencing factor was the insufficient anesthesia(p<0.05). 5. The explanatory power that the pain experience has influence upon dental fear is $R^2$=0.151. Conclusions : The direct pain experience and the insufficient anesthesia experience have the great influence upon patients' dental fear level. Anesthetics and analgesics can be considered as one of the positive methods for pain control.

Purpose: This study aimed to obtain basic data on oral health improvement by investigating the EQ-5D index according to the oral prosthesis status of elderly persons aged 65 years or older in Korea using the Seventh Korea National Health and Nutrition Examination Survey. Methods: In this study, 3,426 elderly persons aged 65 years or older were included to analyze the relationship between the dental prostheses status and EQ-5D index in the collected data. Results: Compared to the "complete denture" in oral prosthesis, EQ in case of no dental prostheses or fixed dental prostheses is comparable to removable prosthetics such as "no dental prostheses," "one fixed bridge," and "two or more fixed bridges." Removable partial denture and complete denture required for the maxillary and mandibular EQ-5D index were significantly higher in "not necessary" than in "complete denture necessary" in all the elderly persons. Conclusion: The condition of the dental prosthesis and the need for a removable partial denture and complete denture for the elderly's EQ-5D index were confirmed, and it was found that the fixed dental prostheses were more effective than the removable dental prostheses. Therefore, oral health education programs for the elderly should be developed to promote dental function and oral health maintenance.
