Turner syndrome (TS) is a chromosomal disorder caused by monosomy of the X chromosome, with complete or partial absence of the second sex chromosome. Anomalies of root morphology have been found to occur more often in patients with TS, which make endodontic treatment challenging and requires special handling. The patients with TS may also have systematic problems such as cardiac or renal malformations, so in treating these patients it is important for clinicians not only to be aware of the characteristic intraoral findings, but also to make the patients have regular dental check-ups to prevent oral complications in advance. An 12-year-old girl who had been diagnosed with TS at the age of 10 years was referred due to discomfort in the bilateral mandibular premolar regions. Dens evaginatus and taurodontism were detected in all the mandibular premolars characteristically. The bilateral mandibular first premolars had three roots and the bilateral mandibular second premolars had periapical lesion with two roots. Due to the complexity of the root canal anatomy, root canal treatment were completed with a dental microscope to ensure adequate visualization. After 2 years of regular follow-up examinations, there were no clinical sign or symptom associated with the teeth, and no periapical lesion, was found. This case report describes the characteristic oral features and dental management of TS patients.

This study analyzed the effects of the nutrient intake on oral health and chewing difficulty according to the age group. The subjects were 5,855 participants of the third Korea National Health and Nutrition Examination Survey(KNHANES VI), 2015, Korea Centers for Disease Control and prevention and aged 20 years and over. The data were analyzed using SPSS Ver 21.0, classified as the difficulty in chewing group (DC) and no difficulty in chewing group (NDC). As a result, the DC rates were 5 times higher in the 60+ year age group (39.5%) than in the 20-39 year age group (8.1%). The DC group were experience periodontal disease (33.4%), dental caries (30.1%), diabetes (41.8%), myocardial infarction (57.3%), arthritis (44.0%), asthma (48.0%), and depression (41.9%). In addition, 86% of the DC group were experiencing speech problems. The DC group had significantly lower intakes (1446.59g), than the NDC group (1666.62g), and the protein, carbohydrate, dietary fiber and other dietary intake were significantly lower. These findings suggest that the chewing difficulty is related to the nutrient intake, and psychological status in the elderly DC group. Therefore, the care of chewing difficulties is essential for the elderly to maintain a healthy lifestyle. Accordingly, oral care and myofunctional therapy are needed to maintain oral health.

Background : This study was undertaken to evaluate the effectiveness of the Bonfils intubation fibrescope for cases of difficult tracheal intubation. Materials and Methods : For patients with an ASA physical status 1 or 2 betwen the ages of 20-90, direct laryngoscopy was performed and the layngoscopic view graded according to the Cormack and Lehane classification. Forty patients with Cormack and Lehane grade 3 or 4 were intubated using the Bonfils intubation fibrescope. During intubation, the success rates for tracheal intubation, overall time to intubation, number of attempts and adverse effects were recorded. The Thyromental and sternomental distances were recorded after the orotracheal intubation. Results : The success rates were significantly higher in Cormack and Lehane grade 3 (96.9%) patients compared to grade 4 (50%) (P<0.01). The time to intubation was significantly faster in patients with grade 3 compared to grade 4 (20 (10-49[7-300]) sec vs. 180 (31-300[10-300]) sec, P=0.01). The number of cases with a $SpO_2$<90% was significantly lower in patients with grade 3 (3.1%) compared to grade 4 (50%) (P<0.01). Conclusion : In patients with Cormack and Lehane grade 3, tracheal intubation using the Bonfils intubation fibrescope appears to be an effective technique for the management of a difficult intubation. However, the Bonfils intubation fibrescope can not always be used for the management of a difficult intubation in grade 4 patients; for these patients other effective instruments should be considered for difficult intubations.

The ocean is a harsh environment and Korea Coast Guard officers often face the threat of death or going missing in the line of duty. In order to promptly identify unknown bodies during mishaps, Korea Coast Guard Research Center has established an identification system using the DNA of its officers. This collected DNA can also be entombed in National Cemeteries when the remains are not recovered. The storage, disposal and quality control of the materials are overseen by the Governing Committee according to the Enforcement Rules for the Human Biological Materials Storage Project for the Identification of Officers Killed or Gone Missing in Action. Approximately 700 bodies are found per year along the Korean coast. An alternative method should be put in place for when identification through fingerprints and teeth are not applicable due to severe decomposition or partial recovery. We believe it would greatly contribute to helping identify the unknown bodies if the storage project could expand its data to include marine industry workers, relevant researchers and those involved in marine leisure activities.

The multifaceted role of chronic inflammation in multistep carcinogenesis has been extensively investigated and well documented. Periodontal diseases are associated with multifactorial agents, including bacterial endotoxins and the generation of an inflammatory response, indicating that poor oral health is associated with a variety of systemic diseases. The association between poor oral health, chronic inflammation, smoking, and increased alcohol consumption as risk factors for tumorogenesis is well established. More recently, associations between oral health and tooth loss and gastric, lung, and pancreatic cancers have been explored, with some studies pointing to smoking and oral health as a common link with an increased risk for malignant disease. In addition, epidemiological studies consistently indicate increased risks of various cancers with periodontal disease or poor oral condition caused by oral bacteria, which may activate alcohol- and smoking-related carcinogens locally or act through chronic inflammation. Appropriate oral care is vital in preventing cancer, as well as many other diseases. Thus, research on the correlation between oral care and periodontal inflammation and cancer is required. This review highlights the association between oral health and the risk of certain malignancies, such as periodontal disease-associated chemoprevention of inflammation" in this sentence.

Wolf-Hirschhorn syndrome(WHS) is a congenital disorder caused by deletions of the short arm of chromosome 4. The most common characteristics are mental and growth retardation, dietary disorder and craniofacial features with a characteristic 'Greek warrior helmet' appearance. The dental characteristic of WHS includes delayed development, tooth agenesis, clefts, microdontia, taurodontism, and severely worn dentition. The purpose of this case report is to describe the dental treatment of a patient with WHS. 3-year-old boy with WHS visited the Seoul National University Dental Hospital for dental treatment. He had difficulty with nasotracheal intubation because of craniofacial anomalies and also had poor oral hygiene due to a limitation of mouth opening and dietary disorder. Due to his airway problem, behavior management and severity of dental conditions, dental treatment was performed under general anesthesia. This case suggests general anesthesia can be chosen with WolfHirschhorn syndrome patients to safely care for their dental problems.
