Objectives : The purpose of this study was identified about oral health status and oral health needs of elderly. Moreover this study would be based further research of development of oral health in elderly. Methods : This study was undertaken to determine the oral health status and the need of oral management of over 65years elderly who were with dental prosthesis in elderly welfare center and Kyung Ro Dong in Kyung Bok and Kyung Nam. The results were as follows. Results : The sample was 200 participants. The demographical characteristic were that 74.0% of participant was female, 29.0% of participant was 75~79 years old, 42.5% of participant was under elementary, and 45.5% of participant was living alone. 43.7% of participant was pain from muscle-skeletal disease, 37.1% of participant was cardiac-vascular disease, and 31.1% of participant was ophthalmic disease. In oral health status, 54.5% of participant was partly artificial tooth and 45% of participant was whole artificial tooth. 78.0% of participant used under 10 years with partly artificial tooth and only 27.4% were satisfaction with artificial tooth. 83.5% of participant used under 10 years with whole artificial tooth and only 26.4% were satisfaction with artificial tooth. In the oral health status of partly artificial tooth, the average of toothbrush was 2 times, 42.2%. The majority method of toothbrush was 'their own freely' 55.0%. The time of toothbrush was 'after meal' 81.8%. The study result showed that majority participant didn't experience of tongue brush, regular examination, scaling, and oral health education. In the need of oral management with the whole artificial tooth, the participant who used longer artificial tooth was significantly higher about artificial irrigation and the method of management(p<.05). The need of participant who answered 'don't gum massage', was higher of xerostomia treatment(p<.01) and halitosis treatment(p<.05). In the need of oral management with the partly artificial tooth, the participant who used longer artificial tooth was significantly higher about regular examination(p<.01), oral cavity massage(p<.05), scaling(p<.05), dental caries treatment(p<.01). The need of participant who answered 'don't satisfaction with artificial tooth' was higher of regular examination and scaling(p<.05). Conclusions : Oral management needs of elderly who kept artificial tooth or denture required were regular dental examination, xerostomia management, management of artificial tooth and irrigation, and management of bad breath. This results meaned the oral health intervention program for elderly was developed regularly.

Purpose: This study aimed to confirm the applicability of gloss polishing using automatic barrel finishing with respect to three-dimensional (3D)-printed resin specimens. The surface roughness and grinding angle of the 3D-printed resin specimens were observed with respect to gloss polishing time using automatic dental barrel finishing. Methods: Herein, experiments were conducted on four types of 3D-printed resin specimens. The specimens, with a thickness of 100 ㎛ each, were printed using a 3D printer. Subsequently, light polymerization was performed on these specimens for 15 min. Post this surface treatment, the specimens underwent grinding for 25 min. This process was followed by gloss polishing at 5-min intervals for up to 25 min using automatic dental barrel finishing. The specimens were photographed using a 3D optical microscope, and their surface roughness and grinding angle were measured. Results: The Ra (centerline average roughness) values of all the specimens, except for crown & bridge 10 group and those in the control group that were not polished using automatic barrel finishing, were <0.2 ㎛. However, polishing time needs to be controlled to realize the desired surface roughness and grinding amount considering the hardness of the resin used. Conclusion: Gloss polishing of 3D-printed resin can be realized using automatic dental barrel finishing. However, polishing time needs to be controlled to realize the desired surface roughness and grinding amount considering the hardness of the resin used.

Background: Patients with autism spectrum disorder (ASD) present challenges in dental treatment cooperation owing to deficits in communication skills and social interaction. Behavioral guidance, sedation, and general anesthesia may be employed to ensure the quality of dental care for individuals with ASD. This study aimed to examine the trends in dental treatment for patients with ASD who visited the Department of Pediatric Dentistry at Dankook University Jukjeon Dental Hospital, an oral health center for the disabled in the Gyeonggi region, over the past 10 years. Methods: This study utilized the order communication system to gather data on sex, age, cooperation level, number of quadrants treated, and administration of sedation or general anesthesia for patients with ASD who visited the Department of Pediatric Dentistry at Dankook University Jukjeon Dental Hospital between January 2013 and December 2022. Results: The total number of patients with ASD increased annually, possibly due to an increase in ASD prevalence and the hospital's designation as a center for disabled oral health. General anesthesia was predominant before 2017, with a shift towards N₂O-O₂ sedation. The most common age group for sedation or general anesthesia was 6-9 years, with a higher prevalence in males than in females. Notably, N₂O-O₂ and midazolam sedation resulted in better cooperation and fewer treated teeth than general anesthesia. Conclusion: This study highlights the evolving trends in dental treatment for individuals with ASD, indicating a shift towards outpatient methods, particularly N₂O-O₂ sedation. The sex distribution aligns with national statistics, emphasizing a higher prevalence of ASD in males than in females. These findings underscore the need for further research to establish evidence-based guidelines for optimal dental care strategies tailored to the unique needs of individuals with ASD.

The high success rate of dental treatment is dependent on the cooperation of pediatric patients during procedures. Dental treatment often causes pain, particularly in children. The factors in providing treatment to pediatric patients include the characteristics and location of the tooth, profoundness of the anesthesia including the type of local anesthetic, and cooperation of the patient. Previous studies have examined several techniques to successfully achieve profound pulpal anesthesia in maxillary permanent teeth. The dentist should select the injection technique to be used based on patient needs. In children, either buccal with palatal injections or buccal with intra-septal injections may be used to anesthetize the permanent maxillary first molar. Buccal with palatal injections are commonly used prior to routine maxillary dental procedures. Currently, there are only a few studies on the employment of buccal with intra-septal injections to anesthetize permanent maxillary first molars in pediatric patients. This review will focus on efficacy of buccal with palatal versus buccal with intra-septal pulpal anesthesia of the permanent maxillary first molars in pediatric patients and aim to determine which technique should be used during routine dental procedures.

Objectives: In this study, existing knowledge and needs of childcare teachers for developing oral health education plans for infants and young children were investigated. Methods: From March to April 2023, an online questionnaire survey led to the collection of data from 150 childcare teachers. Data were analyzed using the SPSS 22.0 program. Results: Importance-Performance Analysis (IPA) revealed that importance and knowledge of oral health education, importance of oral health, and prevention of oral diseases were priority areas, and treatment, symptoms, and causes were priority areas that needed improvement . According to the IPA on the importance of and demand for oral health education support, the importance and demand for an educational plan were both high. Expert education based on educational goals, information sharing, educational environment support, evaluation system, and monitoring was low in importance but high in demand. Conclusions: Oral care habits during infancy are important for maintaining oral health throughout life. Oral care practice should be improved by developing an oral health education plan for childcare teachers to implement.

Background : To do dental treatments successfully for dentally disabled patients who are unable to cooperate to procedures needs deep sedation (DS) or general anesthesia (GA). But there are some difficulties in selecting DS because of some disadvantages such as airway problem etc. But, if we select appropriate cases, DS would be better than GA. Methods : We reviewed total 238 cases of patients who had received dental treatments under GA or DS at the clinic for the disabled in Seoul National University Dental Hospital from November 2007 to February 2009. To compare anesthesia condition between DS and GA, we reviewed preanesthesia evaluation sheet, anesthesia or sedation records and PACU sheets retrospectively. Results : The number of DS cases was 25 (11%) and that of GA was 218 (89%). To maintain DS, intravenous propofol was infused with syringe pump (100%), and sevoflurane (134 cases) or propofol (13 cases) were used for sedation induction. Mean total treatment time for DS was 36 min and 2 hour 25 min for GA. The recovery time at PACU was 44 min for DS and 80 min for GA. There were no severe complications in DS, but 18 cases showed nausea and vomiting in GA. Conclusion : Deep sedation for disabled dental patients should be selected for effective behavioral control in conjunction with general anesthesia, considering duration and pain-evoking potentials of dental treatment and type and severity of patients' disabilities altogether.

Background: The paradigm of tonsillectomy has shifted from a treatment of recurrent throat infection to one of multi-discipline management modalities of sleep-disordered breathing (SDB). While tonsillectomy as a treatment for throat problems has been performed almost exclusively by otorhinolaryngologists, tonsillectomy as a part of the armamentarium for the multifactorial, multidisciplinary therapy of sleep-disordered breathing needs a new introduction to those involved in treating SDB patients. This study has its purpose in sharing a series of tonsillectomies performed at the Seoul National University Dental Hospital for the treatment and prevention of SDB in adult patients. Methods: Total of 78 patients underwent tonsillectomy at the Seoul National University Dental Hospital from 1996 to 2015, and 23 of them who were operated by a single surgeon (Prof. Jin-Young Choi) were included in the study. Through retrospective chart review, the purpose of tonsillectomy, concomitant procedures, grade of tonsillar hypertrophy, surgical outcome, and complications were evaluated. Results: Twenty-one patients diagnosed with SDB received multiple surgical procedures (uvulopalatal flap, uvulopalatopharyngoplasty, genioglossus advancement genioplasty, tongue base reduction, etc.) along with tonsillectomy. Two patients received mandibular setback orthognathic surgery with concomitant tonsillectomy in anticipation of postoperative airway compromise. All patients showed improvement in symptoms such as snoring and apneic events during sleep. Conclusions: When only throat infections were considered, tonsillectomy was a procedure rather unfamiliar to oral and maxillofacial surgeons. With a shift of primary indication from recurrent throat infections to SDB and emerging technological and procedural breakthroughs, simpler and safer tonsillectomy has become a major tool in the multidisciplinary treatment modality for SDB.
