Background: The elderly have, a higher disease morbidity than other age groups due to a decrease in resistance to the disease and have complex diseases, so care should be taken. Accordingly, it is considered important to provide information for improving the health of the elderly. Health information plays an important role in individual health promotion and education, so the degree of exposure to information about oral health of the elderly is expected to have a significant impact on understanding and acquiring information on oral content videos on the importance, prevention, and management of oral health of the elderly in the future. Methods: This study analyzed video content related to oral diseases of the elderly in a total of 150 videos uploaded on YouTube from January 1, 2012 to May 13, 2021, using a total of three books of dental hygiene for the elderly. Results: Forty-nine broadcasters accounted for the most of this information. Among the information providers, there were two dental hygienists. They accounted for 1.3% of all the information providers. The highest number of dental hygienists who broadcasted information was 42 in 2019. The average number of views was 37,303 periodontal diseases, the highest. Among the videos, dry mouth was the most common with 34 oral diseases. Conclusion: The number of images for each disease varies, so it seems that information should be provided in various ways. Dental hygienists should widely improve oral health knowledge by providing various dental hygiene management images for each oral disease to improve the oral health of the general public. In addition, based on the information of the Health Insurance Review and Assessment Service, the development and provision of content should be actively carried out so that people can obtain the information they desire.

Purpose: Soft tissue recessions frequently cause esthetic disharmony and dissatisfaction. Compared with soft tissue coverage around a tooth, the coverage of an implant site is obviously unpredictable. Particularly in the cases of thin mucosa, a significant greater amount of recession takes place compared to thick mucosa. To overcome this problem, this case report demonstrates a two-step mucosal dehiscence coverage technique for an endosseous implant. Methods: A 33-year-old female visited us with the chief complaint of dissatisfaction with the esthetics of an exposed implant in the maxillary left cental incisor region. A partial-thickness pouch was constructed around the dehiscence. A subepithelial connective tissue graft was positioned in the apical site of the implant and covered by a mucosal flap with normal tension. At 12 months after surgery, the recipient site was partially covered by keratinized mucosa. However, the buccal interdental papilla between implant on maxillary left central incisor region and adjacent lateral incisor was concave in shape. To resolve the mucosal recession after the first graft, a second graft was performed with the same technique. Results: An esthetically satisfactory result was achieved and the marginal soft tissue level was stable 9 months after the second graft. Conclusions: The second graft was able to resolve the mucosal recession after first graft. This two-step approach has the potential to improve the certainty of esthetic results.

Objectives : The objective of this study was to compare oral health behaviors and oral health indices between regular scaling group and irregular scaling group. Methods : This study was performed at M Dental Clinic in Busan on 352 dental patients treated between January 2014 and June 2015 using V6.0 software and medical interviews. The 352 patients were divided into 3 groups and oral health behavior (OHB) and oral health indices were compared. Results : The OHB scores significantly differed among Groups C and A. Group C had the lowest number of "Bad" scores for the Simplified Debris Index (S-DI), Simplified Calculus Index (S-CI), and Simplified Oral Hygiene Index (S-OHI). Groups B and A had the lowest number of "Excellent" scores. Group C had the lowest bleeding on probing (BOP), calculus rate (CR) and decayed teeth (DT). Furthermore, Group C had the highest number of missing teeth (MT) and filled teeth (FT). Conclusions : Patients who underwent regular scaling had the highest OHB and oral health index scores. This emphasizes the importance of regular scaling for prevention and early detection of oral disease.

Craniomaxillofacial injuries produce complex wound environments involving various tissue types and treatment strategies. In a clinical setting, care is taken to properly irrigate and stabilize the injury, while grafts are molded in an attempt to maintain physiological functionality and cosmesis. This often requires multiple surgeries and grafts leading to added discomfort, pain and financial burden. Many of these injuries can lead to disfigurement and resultant loss of system function including mastication, respiration, and articulation, and these can lead to acute and long-term psychological impact on the patient. A main causality of these issues is the lack of an ability to spatially control pre-injury morphology while maintaining shape and function. With the advent of additive manufacturing (three-dimensional printing) and its use in conjunction with biomaterial regenerative strategies and stem cell research, there is an increased potential capacity to alleviate such limitations. This review focuses on the current capabilities of additive manufacturing platforms, completed research and potential for future uses in the treatment of craniomaxillofacial injuries, with an in-depth discussion of regeneration of the periodontal complex and teeth.

The purpose of this research is to determine elements affecting the out-of-pocket cost of woman. The sample consisted of 1907 women living Iksan city. The survey was conducted by means of questionnaires. The model used in the analysis of out-of-pocket cost was the Andersen-Newman model, while the analysis techniques used were stepwise multiple regression and path analysis. The number of independent variables used in the analysis was 28 in total, ie 19 predisposing components, 6 enabling components, and 3 need components. In this study, the amount of variance by the model was 17 percent. Number of restricted activity days caused by oral disease, perceived susceptibility of dental disease, having a regular dental care, dental treatment costs, education level and income were found to have significant major effects on out-of-pocket cost. Number of restricted activity days caused by oral disease was the most important variable affecting out-of-pocket cost of woman. Also out-of-pocket cost shows larger effect due to enabling components than frequency of dental utilization.

This study was intended to provide basic data for developing an oral health management program for diabetic patients by understanding their oral health condition and defining the influence of diabetes on oral health. The following results were obtained through intraoral examination and questionnaire surveys done on one hundred and twenty two diabetic outpatients who visited endocrine department at Yeungnam University in Daegu and internal medicine department at Chungmu hospital in Cheonahn for 4 months from November, 2005 to February, 2006. DMF index according to the gender was significantly higher in females only in Filling index (p <0.05). Missing index increased as the age increased (p <0.001). Papillary bleeding index was significantly higher in females (p <0.05). Several indices which show oral status significantly higher as the duration of diabetes increased and as the blood sugar level before meal was higher (p <0.01, p <0.05). In a group that received oral hygiene education, several indices which show periodontal status were significantly lower than those in a group that didn't have it (p <0.001). According to the results, not only diabetic control but also general oral care should be included in self-management education for diabetic patients and this should be accomplished by appropriate oral health education program and staffs.

From the standpoint of general guidelines of a dentist, the following conditions should be considered before replanting a permanent tooth. The avulsed tooth should be without advanced periodontal disease. The alveolar socket should be reasonably intact in order to provide a seat for the avulsed tooth. The extra-alveolar period should be considered, i.e. periods exceeding. 2 hours are usually associated with marked root resorption. But, the above mentioned regulations are often difficult to keep in the actual situation of the medical emergency room, owing it to the delay of primary medical care in multiple trauma patients. The successful cases have been reported with minimal root resorption in the long-term periods, in spite of extra-alveolar periods of several hours and combined alveolar bone fracture. This is a case report regarding the effect of endodontic drainage in delayed replantation after a prolonged extra-alveolar period of the avulsed teeth with alveolar bone fracture.

It is well known that the majority of dental injuries occur in children and adolescent. An injury to the teeth can have serious and long-term consequences, leading to their discoloration, malformation, or possible loss. The emotional impact of such an injury can be far reaching. The majority of dental injuries in the primary and permanent dentitions involve the anterior teeth, especially the maxillary central incisors. Concussion, subluxation, and luxation are the commonest injuries in the primary dentition, while uncomplicated crown fractures are commonest in the permanent dentition. If it is decided to preserve a traumatized primary tooth, it should be carefully observed for clinical and radiographic signs of pulpal or periodontal complications. Radiographs are also examined closely to disclose any damage to the permanent successor. The intervals between reexaminations should be individualized depending on the severity of trauma, the expected type of complications and the age of the patient. Most complications are observed within the first year of the trauma. However, the follow-up evaluation of permanent teeth should continue until treatment of all complications is completed, or until a lost or extracted permanent tooth has been adequately replaced. It is important that the dentist and the other members of the dental team are well prepared to meet the many complex and challenging problems in the care of dental emergencies.

Objectives : The purpose of this study is to investigate the correlation factors to oral health-related quality of life in Chinese students studyng in Korea. Methods : A self-reported questionnaire was filled out by 231 students from November, 2012 to January, 2013. Data were analyzed by t-test, one way ANOVA, and Duncan post-hoc test using SPSS version 19.0. Results : Male students and short period staying students tended to have a higher quality of life. Smokers and large city dwellers tended to have a low oral health-related quality of life(p<0.05). The oral health-related quality of life in Chinese students in Korea was closely related to necessity of dental treatment and past experience of dental treatment services(p<0.05). Conclusions : To improve the oral health-related quality of life in foreign students, it is necessary to provide the early prevention of dental caries and periodontal diseases through the systematic and professional dental health care delivery program for the foreign students studying in Korea.

Purpose: The aim of this study is to compare two different gingival depigmentation techniques using an erbium:yttrium-aluminum-garnet (Er:YAG) laser and rotary instruments. Methods: Two patients with melanin pigmentation of gingiva were treated with different gingival depigmentation techniques. Ablation of the gingiva by Er:YAG laser was performed on the right side, and abrasion with a rotary round bur on the opposite side. Results: The patients were satisfied with the esthetically significant improvement with each method. However, some pigment still remained on the marginal gingival and papilla. The visual analog scale did not yield much difference between the two methods, with slightly more pain on the Er:YAG laser treated site. Conclusions: The results of these cases suggest that ablation of the gingiva by an Er:YAG laser and abrasion with a rotary round bur is good enough to achieve esthetic satisfaction and fair wound healing without infection or severe pain. Prudent care about the gingival condition, such as the gingival thickness and degree of pigmentation along with appropriate assessment is needed in ablation by the Er:YAG laser procedure.
