Background: Depression and cognitive function have a positive effect on the improvement of quality of life and extension of lifespan in the elderly. In addition, it appears as a major factor influencing oral health status. Therefore, this study looked at the relationship between the Geriatric Oral Health Assessment Index (GOHAI), depression, and cognitive function in the elderly using the Korea Longitudinal Study of Aging. Methods: In this study, 4,535 elderly people aged 65 years and over were targeted using the 7th data of the 2018 Korea Longitudinal Study of Aging. A t-test and ANOVA analysis were performed to compare GOHAI, depression, and cognitive function by group. In addition, hierarchical multiple linear regression was performed to understand the effect of the elderly's perceived depression scale and cognitive ability on GOHAI. Results: As a result of adding the depression scale and cognitive function variables to Model 2, the explanatory power was 22%. Educational level, marital status, private health insurance subscription, average monthly allowance, subjective health status, use of dentures, smoking status, economic activity, depression scale, and cognitive function were found to have significant influence (p<0.05). In addition, when controlled and viewed with all factors, depression and cognitive function were found to have an effect on oral health-related quality of life. Conclusion: The findings indicate that depression and cognitive function are associated with oral health-related quality of life in the Korean elderly. As the age increases, the quality of life declines due to depression and cognitive function problems, in addition to oral discomfort, eating disorders, and physical discomfort.

Isoflurane and enflurane are currently used on orthognathic surgery in Korea. Since starting to use enflurane and isoflurane in orthognathic surgery, we have questioned their effect on liver function. Many studies have reported liver function after enflurane and isoflurane anesthesia. Although both enflurane and isoflurane are less hepatotoxic than halothane, some cases of liver dysfunction have been reported after enflurane and isoflurane anesthesia. And, we know that isoflurane is less hepatotoxic than its predecessors, enflurane. But, fulminant liver failure and necrosis were also reported after isoflurane anesthesia. The purpose of this study was to compare immediate liver function in healthy orthognathic surgical patients receiving enflurane or isoflurane anesthesia. To assess the effect of enflurane and isoflurane on liver function, we measured pre-and post-operative serum concentrations of aspartate aminotransferase(AST), and alanine aminotransferase(ALT), alkaline phosphatase(ALP), total bilirubin(Tbil).

A technical refinement for oral commissure reconstruction is presented. The oral commissure has an important role in oral sphincteric function. Once lost, the oral commissure is very difficult to restore and therefore, reconstruction of the oral commissure requires prevention of this function as well as prevention of microstomia. Trauma and tumor excisions are the most frequent reasons that will necessitate reconstruction of the oral commissure. Direct approximation of the wound margins after resection of the corner of the mouth could easily induce microstomia and difficulty in opening. Thus case presented here deals with distortion of noraml mouth angle and acquired microstomia due to burn and tissue deface following shotgun and explosive wounds. The a mucosal flap approach was used to rehabilitate a natural looking mouth angle showing satisfactory results function and esthetic wise.

Introduction : Oral motor function is basic function of sensory exploration, feeding, and communication, that develops from the fetal stage to childhood. Problems with oral motor function result in difficulty within handling food in the oral cavity, decreased swallowing and feeding skills, difficulty with communication, and problems with oral hygiene. To treat these symptoms, oral motor therapy is provided for normalizing sensory adaptation in the oral cavity, and increasing postural control, oral movement and oral motor function. Discussion : The oral motor facilitation technique (OMFT) was developed for increasing general and integrated oral motor function based on the following: 1) understanding orofacial muscular physiology; 2) a comprehensive approach to sensory·adaptation·behavior·cognition; 3) sensorimotor stimulation by a manual approach; 4) motor control and motor learning theory. The OMFT is a new evidence-based treatment protocol, for children and adults with neuromuscular and oral motor problems. Conclusion : The goal of this article is to provide a theoretical background for OMFT development and the basic concept for the clinical application of OMFT. We hope that this article will help oral motor therapy experts to provide effective therapy in a more professional way.

When full denture is being fabricated, pronounciation, recovery of aesthetics of function and mastificatory function should be satisfies for patients. To satisfy for the function of denture, following is the difference between this new way of fabricating and formerly one of it. 1. The size of fabricating tooth which is harmony of original oral structure for patients is deaded by manufacturing labial index and artificial tongue. 2. By the use of artificial tongue and labial index, the arranges of artificial tooth is to become harmony of oral structure. 3. Formation of gingival decided functional impression which is used by impression paste, is harmony of oral structure. Therefore, this full denture can be satisfied with pronouncing oral function of recovery of aesthetics as well as mastificatory through physiological movement of oral tissue not disturbed with anything but cooperated drastically. In manufacturing of this full denture, both dentist and dental technician under cooperation need to proceed the work on the base of importance of communication.

The purpose of this study was to evaluate the status of oral health care in dementia patients living in long-term care facilities and to investigate the effects of this on swallowing function and swallowing-quality of life. The subjects were 60 demented patients who were admitted to long-term care facilities in Gwangju and Jeonnam provinces. Their Oral Health Assessment Tool(OHAT), Clinical Dysphagia Scale(CDS), and Oral Health Impact Profile 14(OHIP-14) were measured. The results of this study were as follows: First, the effect of oral health care on dentition patients using long-term care facilities on swallowing function and swallowing-quality of life was significantly different according to oral care score (p<.05)(p<.01). Second, the relationship between oral health care and swallowing function of dementia patients and swallowing-quality of life. was examined. As a result, oral health care of dementia patients was affected by swallowing function (r=.405, p<.01) the swallowing-quality of life (r=.462, p<.01) and swallowing function were significantly correlated with swallowing-quality of life (r=.351, p<.01). Therefore, the oral health care of users of long-term care facilities was closely related to swallowing function and swallowing-quality of life.

The purpose of the present study is to inspect the satisfied degree of each oral function in geriatric patients with the shortened dental arch and when their prosthetic treatment is on schedule, provide some references to such treatment. For the approach to such study, 521 subjects were reviewed by grouping them according to the number of their remaining teeth, and masticatory function, phonetic function, facial change, and TMJ disorders were inspected and clarified through some questionnaires. Also through the questionnaires, the correlations between the geriatiric patients with the shortened dental arch and dentition and between the geriatiric patients with the Free-end RDP at the shortened dental arch and their oral function were found out with their satisfied degree of oral function. Results or findings from such study are as follows : 1. With regard to their satisfied degree of oral function, there was a significant difference of satisfaction between or among the group having only the anterior teeth and the group having the part of premolars and the group having even the part of molars, however no significant difference of satisfaction appeard between the group having 1st molars and the group having 2nd molars. 2. With regard to their satisfied degree of phonetic function, no significant difference appeared between or among the group having only the anterior part of teeth and the group having even the part of premolars and the group having even the part of molars, and with regard to their satisfied degree of facial change, no significant difference of satisfaction appeared between the group having the part of premolars and the group having even the part of molars. 3. With regard to their satisfied degree of masticatory function, phonetic function, TMJ disorders, and facial change, no significant difference appeared between the group having both the anterior part of teeth and the part of premolars and the group attached with the Free-end RPD on the same conditions of the afore-said group.

Objectives: The aim of this study was to evaluate pulmonary function in patients with mandibular fractures and to determine the pattern of pulmonary functions in these patients. Materials and Methods: This was a cross-sectional study of pulmonary functions in Nigerian non-smoking patients with isolated mandibular fractures managed at our health institution from December 2015 to June 2017. Forced vital capacity (FVC), forced expiratory volume in one second (FEV₁), peak expiratory flow rate (PEFR), and ratio of FEV₁ to FVC (FEV₁/FVC) were measured for all participants using a portable spirometer just before treatment. The pulmonary indices were compared with the predicted reference values for Nigerians to determine the respiratory pattern. Results: Forty participants consisting of six females (15.0%) and thirty-four males (85.0%) with a female to male ratio of 1:5.7 were included in this study. The mean patient age was 34.5±13.1 years (range, 17-63 years). The mean FVC, FEV₁, FEV₁/FVC, and PEFR were 3.8±1.2 L, 3.0±1.0 L, 74.3%±13.8%, and 5.2±2.2 L/s, respectively. Comparison of data with predicted values revealed that 17 subjects (42.5%) had normal pulmonary function pattern while 23 subjects (57.5%) had features suggestive of obstructive and restrictive pulmonary function patterns. Conclusion: Isolated mandibular fractures presented with abnormal pulmonary function pattern.

Objectives: This study aimed to confirm the association between cognitive function and oral health status in the elderly. Methods: In this study, 5,794 respondents, aged 55 or older, who had participated in the 7th aging research panel survey were used. Statistical analyses were performed using a complex samples cross-tabulation analysis, complex samples general linear model, and a complex sample multinomial logistic regression analysis. Results: After analyzing the cognitive function of the elderly according to their oral health conditions, it was found that suspicions of dementia (19.6%) and cognitive function decline (25.9%) were more common for those who wore dentures than for those who did not wear dentures (p<0.001). Compared to those who did not wear dentures, those who wore dentures were linked to a 1.665 times higher suspicion of dementia (p<0.001). In comparison, cognitive decline was 0.964 times lower when the number of natural teeth increased by 1, and it was 0.941 times lower when the oral health evaluation index for the elderly increased by 1 point (p<0.001). Conclusions: As a result of this study, it was confirmed that cognitive function and oral health status are related in the elderly. Therefore, systematic measures for oral health management and oral health promotion should be prepared in tandem with awareness of possible cognitive decline in the elderly.
