Objectives: The purpose of this study was to compare the differences in oral health-related quality of life among elderly people aged over 65 years, in terms of physical, mental and oral health status and to analyze factors affecting their oral health-related quality of life. Methods: From May 9 to June 23, 2017, we randomly visited aged-care community centers in the metropolitan area, and recruited 222 elderly, aged 65 or older. First, each participant completed a questionnaire consisting of 4 general items: 1 systematic disease, and 3 subjective oral conditions. Afterwards, the researchers interviewed the participants to assess their mental status, using MMSE-DS and recorded the responses. Finally, an oral examination was performed to determine the number of remaining teeth. The average oral health-related quality of life according to each characteristic was analyzed by t-test and ANOVA. Hierarchical multiple regression analysis and Pearson's correlation coefficient analysis were used to analyze the correlations between factors and the factors affecting oral health-related quality of life. Results: The mean oral health-related quality of life was 4.15. Participants with 20 or more remaining teeth demonstrated better oral health-related quality of life than those with 19 or less teeth. Higher oral health-related quality of life was also found among elderly without gingival bleeding, self-reported halitosis and dry mouth. In addition, positive correlation with the number of remaining teeth and negative correlation with gingival bleeding, self-reported halitosis and dry mouth, were noted. Finally, the results of the hierarchical multiple regression analysis indicated that remaining teeth, gingival bleeding, self-reported halitosis and education were influential factors in determining the oral health-related quality of life among the elderly. Conclusions: The results of this study confirmed the necessity of better policy support, and the importance of implementing delivered, elderly-centered oral health education program by professionals to prevent tooth loss and manage periodontal diseases.

The purpose of this study was to evaluate the effects of Vitapex on the periapical lesions. Thirteen single-rooted teeth from ten patients who visited the SNU hospital were endodontically treated with Vitapex and Gutta percha cone, and radiographically and clinically evaluated for a period of 1 to 6 months. The results were as follows : 1. The loss of clinical symtoms was observed in all 13 teeth. 2. The reduction of size of periapical lesions in radiographs was observed in 10 teeth. The periapical lesions of remaining 3 teeth also look better in the radiographs. 3. All 13 teeth showed the reduction of radiolucency. 4. The gradual resorption of Vitapex over the root apex was observed.

Partial edentulism has multiple implications in relation to function, esthetics and future rehabilitative treatment. This case report illustrates the management of a patient with extreme consequences of partial edentulism. The main clinical findings were unopposed remaining teeth, overeruption of the remaining teeth, loss of vertical dimension of occlusion, and significant disfigurement of the occlusal plane. Following the diagnostic procedure, a well-coordinated prosthodontic treatment involving liaison with other dental disciplines was indicated. The management involved an innovative combination of fixed and removable prostheses in conjunction with crown lengthening surgery and strategic implant placement. Series of provisional prostheses were applied to facilitate the transition to the final treatment.

Purpose : 1. Retrospectively evaluate the accuracy of tentative diagnosis or impression from the clinico-radio-graphic materials of jaw lesions which showed mixed lesions associated with teeth. 2. To observe the diagnostic importance of the calcified part of the lesions which appear as radiopaque areas. Materials and Methods: 14 cases of jaw lesions which showed mixed lesions associated with teeth were reviewed. These lesions were mostly diagnosed as adenomatoid odontogenic tumors (6 cases) or calcifying odontogenic cysts with (4 cases) or without odontomas (4 cases). The calcified elements of the lesions which demonstrated various sizes and patterns of radiopaque shadows resembled odontoid tissues in some cases but could not be defined in some other cases radiographically. Results : The final histopathologic diagnosis confirmed adenomatoid odontogenic tumors in 4 of the 6 cases. The remaining 2 cases turned out to be odontoma and ameloblastic fibroodontoma. The 4 cases of calcifying odontogenic cysts with odontomas were correct in 3 cases but remaining 1 case was just odontoma. The 4 cases of calcifying odontogenic cysts were proved to be odontogenic keratocyst, calcified peripheral fibroma, unicystic ameloblastoma and squamous cell carcinoma. Conclusion : The diagnostic accuracy of the adenomatoid odontogenic tumors and calcifying odontogenic cysts were high when the lesions show typical appearance. The calcifications which show radiopaque areas could be odontomas or dystrophic calficifations or remnants of bone fragments from resorption.

The purpose of this study was to restorate a patient who has a few remaining teeth with #15,23,24 supported Konus telescope denture in Maxillar and #44,43,33,34 supported Dolder bar retained overdenture in Mandible. Konus telescope and bar retained overdenture was taken better results in retention, support, stability compair with regular Removable partial denture. In Removable partial denture, the change of remaining teeth and edentulous ridge is natural. But Konus telescope and bar retained overdenture is a little effected in this change, so it is possiblble in long-term use. In cosider of patient's medical history and the possibility of additional tooth loss, Konus telescope denture can be easily repaired. Compaired with Konus telescope and bar retained overdenture showed high stability and easy cleansing because of rigid support, cross - arch splinting, and simple design. In delivery, patient had a difficulty with removal of denture and plaque control, but showed better condition, good oral hygienic care. Patient satisfied with denture functionally and esthetically. This study showed Konus telescope and bar retained overdenture was effective for treatment of patient remaing a few teeth in function, esthetic and psycologic satisfaction.

Objectives: Stress is the cause of several illnesses, in older people, stress may also cause various social problems. The oral health of older adults is closely related to the quality of life, and chewing ability is particularly important for their general health. The purpose of this study was to investigate the relationship between stress, the number of teeth remaining, and the chewing ability, which reflects the oral health status among older adults. Methods: This study evaluated the stress level and chewing ability of adults older than 65 years using the 6th (2014-2015) Korea National Health and Nutrition Examination data. The total number of remaining teeth was determined based on the data of the teeth conditions. Results: There was an association between stress and chewing ability among older adults. The odds ratio of chewing function increased by 2.67 times (crude OR=2.67; 95% CI=1.88-3.79) with increased stress. After adjusting, the odds ratio increased to 2.74 times (adjusted OR=2.74; 95% CI=1.88-3.98). Conclusions: Reducing stress may facilitate effective oral health management and improve the overall quality of life in older adults. The findings of this study may help in the discovery of various approaches s to reducing stress in older adults and provide relevant information for oral health education.

The pulp response of posterior composite resins in relation to the thickness of remaining dentin was studied with 120 teeth from 6 dogs, Class V. cavities were prepared on the cervical area of facial surfaces. The thickness of remaining dentin was controlled with Caries Meter$^{(R)}$. The cavities of group A were prepared to show the electrical impedance of 22-26$K{\Omega}$(thickness of remaining dentin:0.4-0.5mm). The cavities of group B, 50-55$K{\Omega}$(thickness of remaining dentin: 0.8-0.9mm). Zinc - Oxide Eugenol cement, Estilux$^{(R)}$ posterior, Heliomolar$^{(R)}$ radiopaque, P-30$^{(R)}$ and Scotchbond$^{(R)}$+P-30$^{(R)}$ were filled in each cavity. After 3days, 1 week, 2 weeks, 4 weeks, 9 weeks and 13 weeks, the teeth and pulp tissue were processed routinely and stained with Hematoxylin and Eosin. Pathological tissue changes were observed with light microscope. The following results were obtained. I. The pulp response of group A cavties was severer than that of group B cavities. 2. In the pulp of group A cavities which were filled with Zinc-Oxide Eugenol Cement, only vascular changes were observed after 3 days and 1 week, severe acute inflammation after 4 weeks, moderate acute inflammation after 9 weeks, and chronic inflammation and formation of granulation tissue after 13 weeks. 3. In the pulp of group A cavities which were filled with Estilux$^{(R)}$ posterior, only vascular changes were observed after 3 days and 1 week. But the inflammatory response has became much severer with the elapsed experimental period. 4. In the pulp of group A cavities which were filled with Heliomolar$^{(R)}$ radiopaque, the inflammatory response with the elapsed experimental period was not severer than that of the pulp of group A cavities which were filled with other materials. 5. In the group B cavities, the difference of pulp response by filling materials was not recognizable. In the group A cavities, the pulp response of Estilux$^{(R)}$ posterior was severest and in order P-30$^{(R)}$, Heliomolar$^{(R)}$ radiopaque was slighter.

A material of 48 patients with 60 avulsed and replanted permanent teeth were followed retrospectively in the period of 1996. 1 to 1998. 12 (mean observation period=1year 7months). The age of the patients at the time of replantation ranged from 9 to 63 years (mean=24 years). Clinical records of patients were reviewed to obtain valid data concerning the extent of injury and treatment provided. Pulpal and periodontal healing states were examined with periapical x-rays and clinical examination procedures (i.e. percussion test and mobility test) at their recall visit. Root ankylosis was found in fifty-two teeth(87%) and root resorption in twenty-four(40%). Only two of the replanted teeth(3%) showed partial regeneration of the periodontal ligament. Six teeth(10%) resulted in tooth loss, but the remaining fifty-four were clinically well functioning. Most of teeth have mild marginal bone loss accompanied by gingival retraction without pathological periodontal pockets. The incidence of root resorption was much higher in younger age group. However, it was not affected by the interval between avulsion and replantation, the condition of supporting tissues, the degree of root formation and the type of splinting, indicating that multiple factors involved in determining the prognosis of replanted teeth. Based on these findings, avulsed teeth in unfavorable conditions (i.e. long extra-alveolar periods, etc.) should be preserved if possible.
