Objectives: This study aims to investigate patient cooperation for dental treatments by dividing patients into two groups with different treatment categories, i.e. orthodontic patients versus non-orthodontic patients. Methods: On December 2016, the study conducted survey targeting 311 orthodontic or non-orthodontic patients who are 20 years old or older living in Seoul and Gyeonggi-do, South Korea. The study subject were informed with the adequate information of the study and signed consent forms. Except for the questionnaire copies from 23 respondents whose answers were insincere those from 288 respondents, equivalent to 92.6% of the data collected, were used in the present analysis. Results: This review intended to clarify any factors affecting patient cooperation for dental treatments shows that the perception of oral condition, the reliability of dentistry, and the patient preventive cooperation had an effect on patient cooperation for dental treatments. Conclusions: The results summarized above suggest orthodontic patients who are familiar with dental treatments by virtue of their regular visits to dental clinics have higher cooperation for dental treatments compared to non-orthodontic patients, and the higher reliability of dentistry leads to higher patient cooperation for dental treatments.

Objective: To determine the changes in dental anxiety, state anxiety, and trait anxiety levels of patients and their parents after 3 months of active orthodontic treatment. Methods: We evaluated 120 patients and one parent of each patient. State Anxiety (STAI-S), Trait Anxiety (STAI-T), and Corah's Dental Anxiety Scale (DAS) were administered before orthodontic treatment (T1) and after 3 months of treatment (T2). Differences in scores between T1 and T2 were compared using paired-sample t-tests and the relationship between the scores of the DAS and the STAI were analyzed using a bivariate two-tailed Pearson correlation test. Results: Dental anxiety and state anxiety levels decreased among the patients after adjustment to orthodontic treatment (p < 0.001). However, 3 months of treatment was not sufficient to decrease the anxiety levels of parents (p > 0.05). Patient trait anxiety affected patient state anxiety and dental anxiety (p < 0.01). Additionally, a significant correlation was found between patient dental anxiety and parent dental anxiety (p < 0.05). Conclusions: Dental anxiety and state anxiety levels decrease after patients become familiar with their orthodontist and they became accustomed to orthodontic treatment. However, 3 months is not a sufficient length of time to decrease parental anxiety levels.

This clinical report describes an orthodontic-prosthodontic interdisciplinary treatment for a patient with multiple missing teeth and unilateral scissors bite. A 47-year-old female presented with multiple missing posterior teeth, anterior large overjet, deep bite, and posterior scissors bite on the right premolar area. Periodontal therapy was performed and followed by orthodontic treatment. The maxillary anterior teeth were initially aligned, then two implants were placed for the left mandibular molars to increase occlusal vertical dimension. The scissors bite between the right maxillary and mandibular premolars were corrected using the miniscrews as an anchorage. Other implants were placed for the right maxillary and mandibular molars after the occlusal planes and occlusal relationship were harmonized. The patient adapted well to altered vertical dimension without any specific problems including peri-implant marginal bone loss. Interdisciplinary approach resolve the complex orthodontic-prosthodontic problems and concluded in successful results.

장애인의 교정 치료는 환자에 따라 치료 목표와 방법이 비장애인의 교정 치료와 달라질 수 있다. 교정 치료를 시작하기 전에 환자의 교정 치료의 한계에 대한 보호자와의 충분한 의사소통이 먼저 이루어져야 하고, 교정 치료는 환자가 견딜 수 있으면서 도움이 되는 방향으로 시행되어야 한다. 또한 교정치료 시 보호자들에게 구강위생관리의 중요성을 항상 강조하고 집에서의 구강 위생 관리를 위한 교육을 반드시 시행해야 한다.

It is difficult to perform orthodontic treatment for cleft lip and palate patient. Although there are many orthodontic appliances to expand narrowed maxillary arch, results are rarely successful and the possibility of relapse is increased due to severe scars. Self-ligating bracket, recently used in orthodontic treatment, suggests solution of crowding by expansion of dental arches. Light and continuous force could apply for orthodontic movement due to characteristic low friction of self ligating bracket, which gives expansion force until dentition reaches its new equilibrium position and it can be expressed as spontaneous lateral expansion with heavy labial tension. This kind of expansion force is thought to be a possibility of expanding the constricted maxillary arch of cleft lip and palate patient. Repositioning of the maxilla by Le Fort I osteotomy in case of severe maxillary deficiency, increases the possibility of relapse because of limitation in anterior movement and adaptation of soft tissue. In these cases, distraction osteogenesis(DO) can be applied for stable result. We report a case of cleft lip and palate patient with narrowed maxillary arch and maxillary deficiency using self ligating bracket and DO.

As the adult population continues to increase, orthodontic treatment for adult patients is becoming more common. This case report describes comprehensive orthodontic treatment of a middle-aged patient with closure of the extraction space without prosthetic restoration. A 55-year-old woman with her maxillary left first premolar extracted because of a periodontal problem, wanted to close the space with orthodontic treatment. Since she had generalized crowding and mild skeletal discrepancy, we planned comprehensive orthodontic treatment, including closure of the extraction space by protraction of the left maxillary molars using miniscrews and aesthetic alignment of anterior teeth. The total treatment period was 28 months. As a result of these treatments, the extraction space was successfully closed, good tooth alignment and satisfactory occlusion were achieved.

교정치료와 악교정 수술을 필요로 하는 환자가 점증하는 현 시점에 비추어, 이에 대한 기술적인 측면의 발전과는 달리 수술-교정 치료 환자에 대한 정신사회학적 혹은 정신심리적 양상에 대한 객관적인 정보는 그리 많은 주목을 받는 편이 아니었다. 수술-교정치료는 과학적인 치료과정이긴 하지만, 어느 정도 심미적 혹은 예술적인 측면을 지니는 선택 치료의 면모를 지닌다. 그러므로 치료에 대한 환자의 주관적인 느낌은 치료 기술이나 치료의 의학적 성공 여부보다 더 큰 영향을 미칠 수 있다. 그러므로, 수술-교정 (혹은 교정)치료에 대한 환자의 반응을 예측하기 위한 정신심리적인 정보는 치료에 유용한 지표가 될 수 있다고 가정할 수 있다. 통제 소재에 대한 연구는 인간의 다양한 행동을 예측하기 위한 유용한 지표로 알려져 왔는데, 본 연구에서는 42명의 수술-교정치료 환자와 성별/연령별로 표본 추출된 42명의 통상적 교정치료 환자를 대상으로 삼아 정신-심리적 비교 및 분석의 방법으로 두 가지 종류의 내외 통제 소재(internal/external locus of control) 검사를 시행하였다. 그 결과 수술-교정치료군과 교정치료군 사이에 통계적으로 유의한 내외 통제 소재의 차이는 나타나지 않았다. 다만 수술-교정치료군에서만 남자가 여자에 비하여 낮은 외적 통제 (높은 내적 통제)의 경향을 보였다. 결론적으로 수술-교정치료 환자의 정신심리적 기반은 성형 수술 환자와는 달리 교정치료 환자와 유사한 경향을 지닌 것으로 생각되었다.

청소년기 교정환자의 통제소재와 교정치료 협조도의 수준을 조사하고 그 관련성을 알아보고자 설문조사를 실시하였다. 경상남도 창원시 소재 3개 치과 병, 의원에서 교정치 료를 받고 있는 청소년 238명(남자 70명, 여자 168명)을 대상으로 실시한 연구조사의 결과는 다음과 같다. 청소년기 교정환자의 협조도 수준은 $4.1{\pm}0.39$로 나타났고, 교정치료를 결정하는 사건들에 대해서 외적 통제-부모의 영향이 강하다고 판단되는 환자일수록 교정치료 협조도가 높은 것으로 나타났다. 통제소재 수준은 $3.49{\pm}0.37$로 나타났고 하위요인 중 내적 통제가 강하다고 판단되는 점수가 $4.46{\pm}0.53$으로 가장 높게 나타났다. 청소년기 교정환자의 내적 통제가 가장 높은 점수로 나타났지만, 실제 교정치료 협조도에 영향을 미치는 통제소재는 부모로 나타났다. 청소년기는 부모로부터 정서적 심리적 독립을 추구하면서도 미성년이기에 완전히 독립할 수 없고 아동에서 성인이 되어가는 과도기적 단계이기 때문에 부모의 영향이 크게 작용할 수 있다. 청소년 교정환자의 교정치료 협조도를 증진시키기 위해서는 환자와 부모의 유대관계를 파악할 필요가 있으며, 환자의 교정치료에 대한 태도나 심리 상태를 파악할 필요가 있겠다. 나아가, 성공적인 교정치료를 결정짓는 중요한 요인 중 하나인 교정환자의 협조도를 증진시킬 수 있는 여러 방법을 모색하기 위한 연구들이 필요하겠다.

Objective: The objectives of this study were to measure pediatric organ and effective doses of cone-beam computed tomography (CBCT) for orthodontic analysis and to compare them to those of panoramic and lateral cephalometric radiography, the conventional radiography for orthodontic analysis. Materials and Methods: Alphard VEGA for CBCT, Planmeca Proline XC for panoramic radiography and Orthophos CD for cephalometric radiography were used for this study. Thermoluminescent dosimeter (TLD) chips were located at 24 anatomic sites of 10-year-old anthropomorphic phantom and exposed during CBCT (C-mode; $200{\times}179mm$ FOV), panoramic and lateral cephalometric radiographic procedures at the clinical exposure settings for 10-year-old patient. Pediatric organ and effective doses were measured and calculated using ICRP 2007 tissue weighting factors. Results: Effective doses of CBCT, panoramic radiography and lateral cephlometric radiography in pediatric clinical exposure settings were $292.5{\mu}Sv$, $19.3{\mu}Sv$, and $4.4{\mu}Sv$ respectively. The thyroid gland contributed most significantly to the effective dose in all the radiographic procedures. Conclusion: Effective dose of CBCT was about 12 times to conventional radiographic procedures for orthodontic analysis in pediatric patient. The use of CBCT for orthodontic analysis should be fully justified over conventional radiography and dose optimization to decrease thyroid dose is needed in pediatric patients.
