Background: The aim of this study was to provide insight on dental fear amongst schoolchildren and evaluate the association between caries experience and fear of dental procedures. Methods: A sample size of 250 students (both sexes) of ages 10-14 years were enrolled in the study. Before dental examination, each participant was informed about the study and given the Children's Fear Survey Schedule - Dental Subscale (CFSS-DS) questionnaire. Children who scored greater than 38 were included in the 'with dental fear' group and those who scored less than 38 were assigned to the 'without dental fear' group. All oral check-ups were carried out on the school premises according to WHO criteria. Results: There were 105 children (42%) who experienced dental fear. As CFSS-DS scores increased, scores on the Decayed, Missing and Filled Surfaces Index (DMFS) also increased. Scores were highest on "injections" followed by "dentist drill" and "feeling of choking". Children were significantly less anxious about items of dental treatment if they had experienced that particular form of treatment. Female participants were found to be more dentally anxious than the male participants. Conclusions: The data revealed dental fear in 10-14 years old children and showed that dental fear scores decreased with increase in age and experience.

Of 42 children, 21 in male and 21 in female, whose ages ranged from 2 to 5 years old, the response of young children to their initial series of dental visits was examined. The results were as follows; 1. With continued experience, the child's response improved, indicating desensitization to dental stress. 2. Experience may reduce the general amount of negative response by allowing the child to accurately distinguish between stressful and non-stressful procedures.

Foreign body (FB) ingestion is commonly seen in the ear nose and throat (ENT) field, with different presentations and sequelae. FBs can arrest in the upper aerodigestive tract or continue further down into either the airway tract to the bronchus or the digestive tract to the intestines. The pathway of an FB depends on the size and shape of the FB and how sharp its edges are. Since the 20th century, the use of disposable stainless-steel needles in the oral cavity has proven to be an effective and safe method for performing various intraoral procedures like dental infiltration or a root canal wash. Complications from their use are rare. Generally, dental needle breakages are caused by patients biting the needle, incorrect injection techniques, or inadequate preventative measures. The sudden movement of a patient during a procedure is one of the most common causes of breakage. Occasionally, needles are swallowed during dental procedures such as a root canal. Here, we report a case of a patient that swallowed a broken needle during a dental procedure. A few days later, the patient presented with neck pain, swelling, and a FB sensation. When the patient presented, she claimed that her symptoms had onset after consuming a meal containing duck meat. Initially, the patient was diagnosed as having ingested a duck bone. However, intraoperatively, the FB was discovered to be an injection needle that had migrated from the throat to the neck.

임상에서 설비의 노후나 고장 등으로 인해 고속 핸드피스의 물 분사에 의한 냉각이 종종 불완전하게 일어날 수 있다. 또한 성인에 비해 치료에 관한 공포가 심하여 비협조적인 소아환자의 경우에는 물의 분사나 고속 흡인기의 사용을 거부하거나 지극히 혐오하는 경우도 드물지 않다. 이처럼 냉각이 충분히 이뤄지지 않은 상황에서 시행되는 다양한 술식은 치수조직에 치명적인 손상을 가할 수 있다. 본 연구의 목적은 임상 수복 술식을 시행하는 동안 각 치아표면에서 발생되는 열이 치수 내부로 전달되는 양상을 조사하기 위함이었다. 석고 블록에 식립된 90개의 하악 제2유구치를 대상으로 수종의 수복 술식을 시행하였고, 해당 치아표면에서 발생되는 열의 온도를 적외선 카메라와 thermography를 이용하여 측정하고, 이를 토대로 유한요소 분석을 통한 치질내 열전도에 관한 평가를 시행하였다. 본 연구에서 시행된 임상 술식의 주수 하 최고 표면 온도는 $30.8^{\circ}C{\sim}43.6^{\circ}C$, 비 주수 하에서는 $51.2^{\circ}C{\sim}103.4^{\circ}C$의 범위를 보였다. 술식 중에서는 치관 형성과정이 가장 높은 온도를, 아말감 제거 과정이 가장 낮은 표면온도를 보였다. 동일 술식 내에서의 주수와 비 주수 조건간에는 모든 술식이 유의한 차를 나타냈다(p<0.05). 유한요소 분석에서 나타난 치수각의 온도변화는 모든 비 주수 조건에서는 큰 폭으로 상승한 반면, 주수 하에서는 전반적으로 미약한 변화를 보였다. 이상의 결과는 고속 절삭기를 사용한 수복 과정에 주수에 의한 충분한 냉각이 치수 생활력의 유지를 위해서 필수적임을 시사해준다. 향후 보다 다양한 술식과 조건을 부여한 유사 분야의 연구가 추천된다.

Objectives: The purpose of this study is to provide basic data for elucidating the clinical experiences of nursing assistants working at dental clinics and for establishing the bases necessary for building a safe working environment for the staff at dental clinics. Methods: From March 28 to August 20, 2022, the study conducted in-depth interviews with nursing assistants working with dental hygienists in dental clinics. The collected data were analyzed using the phenomenological method. Results: The study analyzed the meanings associated with the dental clinical assistance work experiences of nursing assistants in dental clinics. A total of 98 semantic words and 9 sub-categories were extracted, which were ultimately categorized into 4 central meanings: 'imperfect reality', 'work without boundaries', 'putting oneself in someone else's shoes', and 'symbiosis'. Conclusions: The nursing assistants were exposed to an environment where they needed to perform delegated treatment procedures even when they lacked dental work competency. They recognized their gaps in learning and the necessity for designated roles as clinical assistants. Thus, it is necessary to review the allocation and expansion of the work roles of dental practitioners based on the practical and rational realities in dental practice.

We attempted to develop a problem-based learning (PBL) module for integrated education in dental hygiene with the aim of helping students gain clinical competencies necessary for dental hygienist work. To develop the PBL Module for Clinical Dentistry in Dental Hygiene course, the researchers identified literature related to not only educational technology, but also medical science, nursing, dentistry, and dental hygiene. During the design phase of the PBL module, problem scenarios and a plan for the teaching and learning process were developed. Developing problem scenarios involved describing a problematic situation and three questions related with that situation. To cultivate competencies required in dental clinics, each question was related to the diagnosis of a dental disease, dental treatment, and dental hygiene procedures for care. Teaching-learning process plan included the designs of operating environment, operational strategies, learning resources, facilitation of problem-solving process, and evaluation. It is necessary to evaluate the PBL module for integrated education in dental hygiene to confirm its effectiveness.

Foreign body indigestion during dental procedures is uncommon but sometimes associated with severe and life threatening morbidity. The dentist should decide whether multidisciplinary intervention is necessary and how urgently it has to be done. The active removal of foreign bodies depends on the size, shape, type and duration of impaction, along with the location in the gastrointestinal tract. In this report, we presented how to manage gastric foreign body related swallowing during dental procedure and investigated the predictive risk factors, precaution, and prompt management in foreign body ingestion.

Digital dentistry has influenced many dental procedures, such as three-dimensional (3D) diagnosis and treatment planning, surgical splints, and prosthetic treatments. Patient-specific protective appliances (PSPAs) prevent dental injury during endotracheal intubation. However, the required laboratory work takes time, and there is the possibility of tooth extraction while obtaining the dental impression. In this technical report, we utilized new digital technology for creating PSPAs, using direct intraoral scanners and 3D printers for dental cast fabrication.
