Ameloblastoma is the most common aggressive benign odontogenic tumor of the jaws. Because of slow growth and tendency to local invasion of bone and soft tissue, high rates of recurrence are common. The treatment for ameloblastoma is still controversial and poses some special problems in children. Because of growth of the jaw and the different incidence, prognosis of the tumor make the surgical consideration different from adults. Radical resection cause facial deformity, jaw abnormal movement and masticatory disturbance especially to child and adolescents. So conservative treatment as enucleation, curettage is acceptable initial treatment of ameloblastoma in children who can be followed up in a precise, detailed manner. This report describes a case of unilocular plexiform ameloblastoma treated by enucleation and curettage followed by marsupialization.

General anesthesia has been developed in dentistry as a type of management technique to sedate patients who may be uncontrollable or require medical consideration. However, emergency treatment for controlling pain before general anesthesia could be required due to the time for medical evaluation for general anesthesia. There is a greater possibility of developing complications under extended waiting period. A disabled patient who needs dental treatment under general anesthesia underwent pretreatment with intramuscular injection of midazolam and $N_2O-O_2$ inhalation sedation in these cases report.

This study aimed to evaluate various factors related to cooperation levels in pediatric dentistry and determine their correlation with children's cooperation during dental treatments. This study included one hundred children and their guardians who visited the dental hospital at the Chonnam National University. Children and their guardians completed surveys regarding dental fear, dental caries experience, dental treatment experience, temperament, and guardians' dental anxiety, as well as the background characteristics of the children. Based on these data, factors associated with children's cooperation during dental treatment were investigated. Dental fear, caries experience during the primary and mixed dentition stages, and temperament traits such as shyness and negative emotionality significantly impacted children's cooperation during dental visits, with higher levels of these factors corresponding to lower cooperation. The extent of dental experience also modestly influenced children's cooperation, with higher levels of cooperation observed in children with greater dental experience. Additionally, children's dental fear was strongly correlated with guardians' dental anxiety, increasing as guardians' anxiety levels increased. Twelve-year-old children exhibited significantly lower levels of dental fear compared to other age groups, and regardless of cooperation levels, injections (shots) were identified as the primary factor inducing dental fear among the children. To improve children's cooperation in pediatric dentistry, strategies should focus on alleviating their fears and adopting an individualized approach that consider their oral health status and temperamental traits.

The success in periodontal-prosthetic therapy lies in patient satisfaction with subjective and customized treatment regimen that has been refined for individual needs. To fulfill these requirements, multiple predictors may have to be taken into consideration in the comprehensive treatment planning. Incorporation of complex factors that guarantee the evidence-based therapy would include, but not limited to, osseous morphology, biotype of gingival around abutment, bone morphology of interdental bone and those around furcation area, abutment or bridge mobility. The periodontal-restorative interface should be of mutually protective. Also strategic and esthetic value of abutment teeth to be restored should also be taken into consideration. Taken together, all these should work in concert to enhance the predictability and longevity of abutment teeth in periodontal-prosthetic therapy.

In this report, we describe a case involving a 34-year-old woman who showed good treatment outcomes with long-term stability after multidisciplinary treatment for unilateral cleft lip and palate (CLP), maxillary hypoplasia, severe maxillary arch constriction, severe occlusal collapse, and gingival recession. A comprehensive treatment approach was developed with maximum consideration of strong scar constriction and gingival recession; it included minimum maxillary arch expansion, maxillary advancement by distraction osteogenesis using an internal distraction device, and mandibular setback using sagittal split ramus osteotomy. Her post-treatment records demonstrated a balanced facial profile and occlusion with improved facial symmetry. The patient's profile was dramatically improved, with reduced upper lip retrusion and lower lip protrusion as a result of the maxillary advancement and mandibular setback, respectively. Although gingival recession showed a slight increase, tooth mobility was within the normal physiological range. No tooth hyperesthesia was observed after treatment. There was negligible osseous relapse, and the occlusion remained stable after 5 years of post-treatment retention. Our findings suggest that such multidisciplinary approaches for the treatment of CLP with gingival recession and occlusal collapse help in improving occlusion and facial esthetics without the need for prostheses such as dental implants or bridges; in addition, the results show long-term post-treatment stability.

Objectives : The purpose of the study is to investigate the relationship between appearance perception, appearance satisfaction, and self-esteem in adolescents who demand the orthodontic treatment. Methods : A total sample of 403 high school students filled out the questionnaire and data were analyzed by using SPSS ver 20.0. for n (%), chi-square test, t-test, and a logistic regression. Results : Girl students (68.3%) tended to have a higher demand for orthodontic treatment than male students (31.7%). Higher appearance perception(t=6.967, p<0.001), lower appearance satisfaction(t=-5.477, p<0.001) and lower self-esteem(t=-7.333, p<0.001) were higher in group of demand for orthodontic treatment. The logistic regression analysis revealed that a gender, self-perception of their teeth, appearance perception, and self-esteem were significantly associated with orthodontic treatment demand. Conclusions : The result of this study will provide basic data for the consideration of psychosocial factors in orthodontic treatment in adolescents.

Purpose: The characteristics of spatial allocation planning in dentistry through examining the dental hospitals in Korea and comparison between them are necessary for the development of planning of the dental healthcare system. This study has been started to provide basic informations such as zoning, allocation distribution, and space configuration for the planning of dental hospital architecture. Methods: Literature review of dental care departments and investigation on current status of dental hospital in Korea have been conducted. The spatial allocation and space configuration of eleven dental hospitals have been analyzed. Results: The result of this study can be summarized in three points. The first one is that dental hospitals in Korea are consisted with eight to eleven dental care departments and they are divided with the horizontal allocation type with three to four departments in a floor for the spatial communication or the vertical allocation type with a department in each floor for the independent space. The second one is that oral medicine and oral maxillofacial radiology are located near the main entrance, orthodontics and pedodontic dentistry in lower level, prosthodontics in upper level, and conservative dentistry and periodontics have no specific spatial consideration. The third one is that the factors to consider the allocation planning are zoning for examination & diagnosis, basic practice, adolescence, surgery, circulations for patient, dentist, staff, different access for department like as easy access for reception and pedodontic dentistry, enclosure space for prosthodontics and surgery, frequency of visit and treatment care time, and change of treatment concept from treatment department to disease control corporative practice. Implications: This study is the starting point for the research of spatial configuration in dentistry and it is necessary to analyze the architectural planning to develop the dental healthcare system.

Fibrodysplasia ossificans progressiva(FOP)는 연조직의 진행성 이소성 골경화를 특징으로 한다. 상염색체 우성 유전을 따르지만 대부분의 FOP 환자는 ACVR1 유전자의 새로운 돌연변이로 인해 나타난다. 아주 작은 외상조차도 연조직의 영구적인 골경화를 유발할 수 있기 때문에 일반적인 치과치료에 의해서도 합병증이 생길 수 있다. FOP 환자의 치과치료 시 전달마취, 과도한 근육의 스트레칭, 생검 등은 모두 금기이다. 현재까지 알려진 FOP의 효과적인 치료법은 없다. FOP는 유병률이 매우 낮으며 초기에는 오진되는 경우가 많아 부적절한 처치로 인해 증상을 더욱 악화시키는 경우가 많다. 따라서 조기진단 및 합병증 발생을 줄이기 위한 예방적 조치가 가장 중요하다. 본 증례는 서울대학교병원 소아정형외과에서 특발성 FOP로 진단을 받고 하악 좌, 우측 유중절치의 만기잔존을 주소로 소아치과에 의뢰된 8세 1개월의 남아에서 증상의 악화없이 치과치료를 시행하였기에 이와 관련하여 FOP환자의 특징적 소견 및 치과치료 시 고려사항을 고찰하기 위함이다.

Although the long-term success of osseointegrated endosseous implants for the support of fixed dental prostheses has been reported, the increasingly widespread use of implant-supported prostheses has led to problems associated with their structural integrity. The most common biomechanical complications observed in dental implant treatment are fracture and screw loosening. The nature of loosening or fracture of dental implant components is complex, since it involves fatigue, fitness, and varied chewing patterns and loads. To assess the service life of the components of the prosthetic system, a knowledge of the loads transmitted through the system is necessary. Design of the final restoration and occlusion in relation to the geometry of a prosthetic restoration has a great influence on the mechanical loading of the implant. It is proposed that control of force in oral cavity may play a larger role in failures than previously believed. Based on theoretic consideration and clinical experiences with dental implant, this article gives simple guidelines for controlling these loads.
