Background: Patients with autism spectrum disorder (ASD) present challenges in dental treatment cooperation owing to deficits in communication skills and social interaction. Behavioral guidance, sedation, and general anesthesia may be employed to ensure the quality of dental care for individuals with ASD. This study aimed to examine the trends in dental treatment for patients with ASD who visited the Department of Pediatric Dentistry at Dankook University Jukjeon Dental Hospital, an oral health center for the disabled in the Gyeonggi region, over the past 10 years. Methods: This study utilized the order communication system to gather data on sex, age, cooperation level, number of quadrants treated, and administration of sedation or general anesthesia for patients with ASD who visited the Department of Pediatric Dentistry at Dankook University Jukjeon Dental Hospital between January 2013 and December 2022. Results: The total number of patients with ASD increased annually, possibly due to an increase in ASD prevalence and the hospital's designation as a center for disabled oral health. General anesthesia was predominant before 2017, with a shift towards N₂O-O₂ sedation. The most common age group for sedation or general anesthesia was 6-9 years, with a higher prevalence in males than in females. Notably, N₂O-O₂ and midazolam sedation resulted in better cooperation and fewer treated teeth than general anesthesia. Conclusion: This study highlights the evolving trends in dental treatment for individuals with ASD, indicating a shift towards outpatient methods, particularly N₂O-O₂ sedation. The sex distribution aligns with national statistics, emphasizing a higher prevalence of ASD in males than in females. These findings underscore the need for further research to establish evidence-based guidelines for optimal dental care strategies tailored to the unique needs of individuals with ASD.

The purpose of this study was to evaluate the factors related to xerostomia in patients with systemic diseases, and the results were analyzed through t-test, ANOVA, and multiple linear regression analysis. There were 62 respondents (56.9%) who reported dry mouth and the season of the most severe dry mouth was reported to be the highest during winter. According to the analysis made in the relationship of xerostomia with the awareness of general health and health behavior, the group that understood their own health poorly, had more than two kinds of diseases, and had been administered more than two kinds of daily medication showed higher xerostomia. Also, those who experienced desperation, had high dryness in other parts of the body, and heavy snoring were more aware of xerostomia (p<0.05). According to the analysis made in the relationship between xerostomia and awareness of oral health state, the group that understood their oral health poorly and had pain in the oral mucous membrane and halitosis was more aware of xerostomia (p<0.05). According to the analysis made in the relationship between quality of life and xerostomia, the group that showed high level of problem in daily living and stress and were self-conscious and felt tense due to halitosis reported more xerostomia (p<0.05). Finally, xerostomia was most correlated with consciousness of the eyes of others due to halitosis followed by the number of transferred systemic diseases and stress level. Based on such results, xerostomia was understood to be an obstacle in maintaining favorable social life and health. Since xerostomia was shown to be related to the number of transferred systemic diseases, the dental professions are asked to further improve their understanding not only on oral health but also systemic diseases. Therefore, these efforts are expected to prevent xerostomia and reduce various complications caused by xerostomia.

Purpose: The purpose of this report was to describe the clinical and microbiological characteristics of two rare cases of necrotizing stomatitis, and the outcomes of a non-invasive treatment protocol applied in both cases. Methods: We report two cases of necrotizing stomatitis in a rare location in the hard palate of a 40-year-old woman and a 28-year-old man. Neither had a relevant medical history and both presented with highly painful ulceration in the palate and gingival margin that was accompanied by suppuration and necrosis. 3% hydrogen peroxide was applied to the lesions using sterile swabs, and antibiotic and anti-inflammatory treatment was prescribed to both patients in addition to two daily oral rinses of 0.2% chlorhexidine. Results: In both cases, radiological examination ruled out bone involvement, and exfoliative cytology revealed a large inflammatory component and the presence of forms compatible with fusobacteria and spirochetes. There was a rapid response to treatment and a major improvement was observed after 48 hours, with almost complete resolution of the ulcerated lesions and detachment of necrotic areas with partial decapitation of gingival papillae. Conclusions: Necrotizing periodontal lesions can hinder periodontal probing and the mechanical removal of plaque in some cases due to the extreme pain suffered by the patients. We present a non-invasive treatment approach that can manage these situations effectively.

In the past, many dentist were interested mainly in the mechanical aspects such as tooth preparation and retainer types for making dental restoration. But, these days, the concept of restorative treatment emphasizes the importarce of gnatic system and masticatory muscles in addition to oral cavity. So, the current considerations for the fixed prosthodontic treatment include the stabilization of temporomandibular joint and neuromuscualr system and the relationship of periodontal ligament and occlusion. To achieve the above objectives, occlusal splint has been used as one of the mouth preparations for restorative treatment. The objectives of occlusal splint are as follows; 1. To use as preliminary application for periodontal-occlusal treatment 2. To provide proper vertical dimension 3. To control abnormal habits and parafunction 4. To treat the temporomandibular disease and myofascial pain 5. To establish the new therapeutic position In some cases, the patients had improper vertical dimension and occlusal interferences caused by prostheses reconstucted using centric relation recorded without considering the health of TMJ and manticatory muscle. And these prosthesis act as primary source that cause pathologic phenomenon in periodontal ligament, muscles and TMJ. Physiologically, in order to make the treatment occlusion guided by proper centric relation method, the method should be guided after the use of occlusal splint for some period. The main objective of prosthetic treatment is to maintain the function and health of stomatognathic system. So, one of the most important things that have to be performed by clinicians is a clinical ability to do the correct diagnosis and treatment planning based on the stomatognatic function and occlusion.

Low temperature atmospheric pressure plasmas (APPs) have been known to be effective for living cell inactivation in the water [1]. Many earlier research found that pH level of the solution was changed from neutral to acidic after plasma treatment. The importance of the effect of acidity of the solution for cell treatments has already been reported by many experiments. In addition, several studies have demonstrated that the addition of a small amount of oxygen to pure helium results in higher sterilization efficiency of APPs [2]. However, it is not clear yet which species are key factors for the cell treatment. To find key factors, we used GMoo simulation. We elucidate the processes through which pH level in the solution is changed from neutral to acidic after plasma exposure and key components with pH and air variation with using GMoo simulation. First, pH level in a liquid solution is changed by He+ and He(21S) radicals. Second, O3 density decreases as pH level in the solution decreases and air concentration decreases. It can be a method of removing O3 that cause chest pain and damage lung tissue when the density is very high. H2O2, HO2 and NO radicals are found to be key factors for cell inactivation in the solution with pH and air variation.

Dentists have been striving to find ways to relieve patients' pain and discomfort. The prestige of dentists is made up of dentists' self-sacrifice, academic research and pursuit of patients' well being. However, nowadays the dentists' prestige has been lost and practice on humanity has merely existed. At this time, it is meaningful to shed new light on life of a pioneer in Korean dentistry and take some time for self-examination. Today, we are going to look into life of Dr. Jong-Suh Ahn and his achievements in Korean dentistry. In 1925, Dr. Ahn Jong Suh graduated from KyungSung Dental school as a first graduating class. Then, he learned advanced dentistry at Severance Hospital and in April of 1932 as a young dentist with full of potentials, he opened his dental clinic in Tianjin, China. As an awakening Korean, in 1925 he organized an association of Korean dentists, called HanSung Dental Association and worked as a secretary to manage general affairs. Han Sung Dental Association later became today's Korean Dental Association. On December 9th, 1945, he founded ChoSun Dental Association. He accomplished great deals during his five consecutive terms as a chairman and held other important positions with prestige to lead and expand the scope Korean dental association. There were three other successors to Dr. Ahn as the presidents of Dental Association. Dr. Yong-Jin Kim had a great interest in internal affairs and dental materials. Dr. Myung-Jin Park was active in scientific affairs and Dr. Dong-Chan Han focused on smooth operation of the association. From 1945 to 1963, Dr. Ahn submitted important agendas such as dentist's qualification, scientific and academic affairs, general affairs, dental materials, public oral health, and dental administration to Dental Association's general meeting and central committee. Dr. Ahn overcame hardships of Japanese imperialism, celebrated independence of Korea, experienced 6.25 Korean War and lived through evolving Korean dentistry in 1960s. Dr. Jong-Suh Ahn, who showed the prestige of dentist and expanded the scope of dental association, is exemplary to all dentists.

Objectives: The aim of this study was to analyze the correlation between Ryodoraku and two pattern-identification questionnaires in patients with Burning Mouth Syndrome (BMS). Methods: The study participants were 30 patients with BMS who visited the Oral Diseases Clinic of Kyung Hee Oriental Medicine Hospital from June to November, 2019. The Ryodoraku test and two pattern-identification questionnaires were administered to all patients. Measurements included the average Ryodoraku score, which is called the Total Average (TA), and each score on the Ryodoraku point scale. The degree of Yin-deficiency, Qi-stagnation, and pain were assessed with the Yin-deficiency Questionnaire (YDQ), Qi-stagnation Questionnaire (QSQ), and Visual Analogue Scale (VAS), respectively. Results: The average TA score was 29.90. The LF5 (p=0.013) and RF5 (p=0.016) scores were lower than the TA scores, and the RH5 (p=0.020) and RH6 (p=0.006) scores were higher than the TA scores. A negative correlation was detected between the YDQ scores and the LH1 (r=-0.366, p=0.046), LH2 (r=-0.507, p=0.004), LH3 (r=-0.374, p=0.042), RH1 (r=-0.361, p=0.050), RH2 (r=-0.403, p=0.027) points. The LF5 (p=0.050) and RF2 (p=0.048) scores were lower in the patients with Qi-stagnation patients than without Qi-stagnation. Conclusions: Our results suggest that low TA and Ryodoraku scores on LF5 and RF5 and high Ryodoraku scores on RH5 and RH6 could be quantitative indicators for the diagnosis of BMS. The LH1, LH2, LH3, RH1, RH2, LF5, and RF2 scores could also be an indicators for diagnosis of Yin-deficiency and Qi-stagnation in patients with BMS.

Although transfusion of blood and plasma products are accepted as the principle means of transmission of HCV, other parenteral methods, such as acupuncture, tattooing needles, piercing, and surgery are possible methods of transmission of HCV. We managed a case of chronic hepatitis C acquired through ear piercing and acupuncture. A 10-year old girl presented with nausea, abdominal pain, and anorexia for 1 month. Her laboratory finding showed the following: AST/ALT, 865/1,290 IU/L; positive anti-HCV Ab; and HCV RNA. One year previously, she was treated with acupuncture for an ankle sprain and 2 years previously, she had her ears pierced. Laboratory findings of family members showed AST/ALT in the normal ranges, and negative anti-HCV Ab and HCV RNA. The pathologic findings of a liver biopsy revealed chronic hepatitis with mild lobular activity, moderate porto-periportal activity, and portal fibrosis. She was treated with pegylated interferon ${\alpha}$-2a and oral ribavirin for 6 months, after which the clinical symptoms and laboratory findings improved.

A 36-year-old woman with a history of spontaneous abortion and photosensitivity was admitted to our hospital with periumbilical pain and lower extremity edema. The preoperative CT scan revealed massive inferior vena cava thrombus, which extended from the suprarenal portion of the vena cava to the hepatic vein. The laboratory data showed an elevated level of anticardiolipin antibody, which suggested the diagnosis of antiphospholipid syndrome. After medical management, she underwent an operation for removal of an vena cava thrombus by performing cavectomy and thrombectomy. After the operation, she has been taking oral anticoagulation and she is doing quite well at 9 months after her operation.

Nicotine poisoning arising from the use of nicotine patches is rare. However, because nicotine patches are classified as an OTC drug, the risk of misuse or abuse is increasing. Nicotine poisoning using nicotine patches shows an unusual clinical presentation compared to that from oral ingestion of multiple doses of nicotine. We present a case of misused nicotine patches that cause a nicotine poisoning. A thirty-nine year-old healthy man visited the ER with complaints of an intermittent cramping abdominal pain with nausea and vomiting. Upon physical examination, there were no specific findings except increased bowel sounds, and the patient's initial laboratory findings were also unremarkable except for an increased bilirubin level. CT revealed a mild degree of fatty liver. The patient's symptoms did not improve any further with conservative management. During his ED stay, we meticulously took his history again, and we discovered that he had used nicotine patches for three days, six days before admission, and had misused the nicotine patches as NSAID patches. The patient's diagnosis of nicotine poisoning was confirmed by a urine cotinine level ten times the normal value. After a 12-hour stay in the ED, his symptoms disappeared without any specific management.
