Retromolar pad is one of anatomical landmarks to use clinically for determining of specific occlusal plane level in edentulous patients and is inherently a soft tissue mass; located at the distal end of mandible and should be covered with denture. The shapes of retromolar pad show variability because it might be inevitable to be resultant forms from healing and remodeling process after the extraction of last molars. Considerations would be focused on those resultant shapes and classification with anatomical relationships and clinical significances.

Burning mouth syndrome (BMS) is defined as the xerostomia, burning sensation and various discomfort of tongue and oral mucosa. BMS can occur in both men and women, but is more frequent in middle-aged menopausal women. Because exact cause can't be identified clearly and it is hard to make diagnosis in clinic, the purpose of the treatment have been to relieve symptoms. Etiology of BMS is divided into local, systemic, and psychological factors. ${\alpha}$-lipoic acid, clonazepam, supplemental therapy and cognitive behavior therapy can be prescribed for BMS. Nowdays, many experts focus attention on effect of combination therapy. It is necessary to solve the symptoms of the patients by combination of pharmacological approach and psychotherapy with cognitive behavior therapy considering the factors in various aspects.

Background: In order to emphasize the importance of clinical dental hygienists-led dental hygiene management processes for those with systemic diseases, we tried to identify systemic diseases affecting dental implants based on clinical data. Methods: In order to identify systemic diseases affecting dental implants, literature review was conducted from March 1 to May 31, 2023, and the search period was for research papers published in domestic and foreign academic journals from January 2000 to December 2020. Domestic databases used for search use RISS, Nuri Media(DBpia), and Korea Academic Information (http://www.papersearch.net ; KISS), while overseas databases searched Pubmed for dental implant failures, implants, systemic diseases, and Dental implant and system disease. Results: The cumulative survival rate of implants averaged 94.3 percent and the failure rate was 5.7 percent. Clinical analysis of systemic diseases related to implants accounted for the highest frequency with 13 (100.0%), followed by 8 (61.5%) studies on high blood pressure and smoking, 7 (53.8%) cardiovascular diseases, and 5 (38.5%). In addition, liver disease, thyroid abnormalities, blood abnormalities, organ transplants and infectious diseases were confirmed. Conclusion: Since unregulated systemic diseases are a risk factor for implant failure, clinical dental hygienists should continue to maintain healthy oral conditions by sharing information with patients during periodic preventive dental hygiene management processes such as dental hygiene assessment.

A total of 580 patients, who visited and received an orthodontic diagnosis in the Department of Pediatric Dentistry, Seoul National University Dental Hospital from 2017 to 2019, were investigated in this study. The aim of this study was to evaluate skeletal patterns of pediatric orthodontic patients determined with lateral cephalometric analysis and to analyze the relationship between skeletal pattern and probable associated clinical features. Also, the modality of orthodontic treatment for each skeletal classification was investigated to aid in therapeutic decisions. Patients aged 7 year accounted for the largest age group; 54.2% of patients showed a skeletal class I pattern, 22.2% showed a skeletal class II pattern, and 23.6% showed a skeletal class III pattern. Bi-maxillary retrusion for skeletal class I, retruded mandible with normal positioning of the maxilla for skeletal class II, and retrusion of the maxilla with protrusion of the mandible for skeletal class III were the largest subgroups by skeletal pattern. Brachyfacial type accounted for 55.0% of patients, followed by 31.9% of mesofacial type and 13.1% of dolichofacial type. The prevalence of anterior crossbite in the study was 43.3%, higher than that in previous studies.

This study aimed to evaluate the courses of pediatric dentistry based on correlation analysis between scores of objective structured clinical examination (OSCE) and related subjects for 79 fourth-year students. The score of theory were related to preclinical (r = 0.449, p = 0.000) and clerkship (r = 0.437, p = 0.000) each, but the scores of clerkship were not related to OSCE. To make the students skillful for clerkship, more professor's firsthand teaching on treating patients and adequate numbers of clinical professors are required. Patients who come to the university dental hospital prefer to be treated by professors rather than students. In these circumstances, educational conditions should be arranged by ensuring the number of professors for teaching students to improve their clinical competence through direct instruction and feedback to students. In addition, pragmatic improvement plans, which allow continuous education and evaluation about basic techniques to be examined in the clinical practice course, should be compromised with the more concrete evaluation of the curriculum in order to evaluate theoretical knowledge and technical trainings to be well exercised and deepened in the practical clinical field.

Nowadays computer-guided "flapless" surgery for implant placement using templates is gaining popularity among clinicians and patients. The advantages of this surgical protocol are its minimally invasive nature, accuracy of implant placement, predictability, less post-surgical discomfort and reduced time required for definitive rehabilitation. Aim of this study is to describe the digital implant protocol, thanks to which is now possible to do a mini-invasive static guided implant surgery. This is possible thanks to a procedure named surface mapping based on the matching between numerous points on the surface of patient's dental casts and the corresponding anatomical surface points in the CBCT data. With some critical points and needing an adequate learning curve, this protocol allows to select the ideal implant position in depth, inclination and mesio-distal distance between natural teeth and or other implants enabling a very safe and predictable rehabilitation compared with conventional surgery. It represents a good tool for the best compromise between anatomy, function and aesthetic, able to guarantee better results in all clinical situations.

Purpose: Prosthodontics education of Korean dental schools is developing under liberal regulation according to the character of each school. Diversity in the current environment and condition for each school make it impossible to apply the same and uniform education curriculum. Therefore the purpose of this paper is to analyze and validate the status of the 2012 prosthodontics education curriculum in Korean dental schools, and to suggest future direction. Materials and methods: A survey was completed by all the 11 dental schools in South Korea. Results: The number of students, age, sex, credits for prosthodontics lecture and practice courses, evaluation method before senior students' clinical practice, modalities for minimum requirement for graduation, beginning and finishing timing of clinical practice and faculty personnel involved in the education varied among the dental schools. Conclusion: High-quality educators leading an expanded teaching personnel are required, education hours must be increased and efficient curriculum must be organized to improve the prosthodontics education.
