Cerebral Palsy is a genetic term referring to abnormalities of motor control caused by damage to a child's brain early in the course of development. Due to the impairment of balanced perioral muscle development, the prevalence of malocclusions in patients with cerebral palsy such as maxillary protrusion is high. But most clinicians may feel uncomfortable to treatment of these problems. Here a case report about mitigation of maxillary anterior teeth protruded in patient with cerebral palsy. 8y 4m old boy who have cerebral palsy visited our dental hospital. He showed severely protrusive maxillary anterior teeth with mouth breathing and could not close his mouth. He and his mother wanted to improve dental and facial esthetic problem. Specially designed or modified intraoral fixed appliance and rubber elastic chain was used in the therapy. Treatment carried out for 8 months and we could observe maxillary incisor angle was improved and mouth breathing habit was stopped. In conclusion, modified fixed appliance therapy for the patients with cerebral palsy might be useful. Continuous rehabilitation training of lips should be followed after treatment to correct imbalance of muscle tone.

Takayasu's arteritis(TA) is commonly known as Aortitis Syndrome, Pulseless disease. Cardiac involvement due to vascular occlusion or stenosis is common in TA, expressed in forms of heart failure, aorta hypertension, alteration of artery or cardiac muscle. In this case, a 9 year old boy was referred to our dental clinic by his cardiology doctor for delayed eruption and gingival hyperplasia on upper incisor. The patient was diagnosed as TA with history of taking Amlodipine, a calcium channel blocker as hypertension medication. He was diagnosed as drug induced gingival hyperplasia. Under taking preventive antibiotic, gingivectomy was done. In case dental treatment of TA patient, dentist should be aware of two possible problems. First is the antibiotic prophylaxis due to the high risk of endocarditis. Second is the possibility of drug induced gingival hyperplasia.

Kabuki syndrome is characterized by typical facial features (elongated palpebral fissures with eversion of the lateral third of the lower eyelid; arched and broad eyebrows; short columella with depressed nasal tip; large, prominent, or cupped ears), minor skeletal anomalies, persistence of fetal fingertip pads, mild to moderate intellectual disability, and postnatal growth deficiency. A 6-year-old male with kabuki syndrome was referred from the local dental clinic for left facial swelling and dental caries on all primary molars. He was treated for acute periapical abscess with incision and drainage under physical restraint, and left maxillary second primary molar was extracted. Other caries treatment was performed under general anesthesia. As the syndrome involves many different medical problems, special cares should be considered. Dental treatment should be carried out in comprehensive consultation system.

This study examined the demographic and oral behavioral risk factors for periodontal disease in adult workers. The research subjects and method were conducted targeting 1,650 Korean adult workers aged 20-64 utilizing the data from the fifth Korea National Health and Nutrition Examination Survey (KNHANES V-3). As a result of this study, the periodontal tissue patients showed the risk factors for gender, age, income level, educational level, systemic disease, sleep hours, oral health level, biting trouble, and chewing difficulty. In terms of the greatest influence, the workers with problems with biting and chewing had a more than 3.5 times higher likelihood of being affected by periodontal disease. The findings of this study show that there are a variety of risk factors for periodontal diseases in Korean workers. To reduce the prevalence rate of periodontal disease, regular checkups including dental checkups and sufficient sleeping will be necessary, and the level of stress should be decreased. In addition, the government should take the required measures to remove the socioeconomic inequality, such as income gap or educational divide.

Cerebral palsy is an umbrella term encompassing a group of non-progressive non-contagious motor conditions that cause physical disability in human development. Motor disorder of cerebral palsy is often accompanied by disturbances of sensation, perception, cognition, communication, behavior and seizure disorder. Disharmony of motor function leads to frequent falling down. Moreover patients have high prevalence of class II malocclusion. Compared to normal patients, the patients with cerebral palsy tends to have high prevalence of recurrent trauma and bruxism which make restoration of the anterior tooth more difficult. This case report is consisted of three cases of cerebral palsy patients who have challenging problems with restoration of anterior teeth.

McCune-Albright syndrome (MAS) is a rare disease characterized by fibrous dysplasia (FD), Cafe-au-lait spots, and endocrine disorder. A 4-year-old girl with MAS visited the clinic with a chief complaint of facial asymmetry and bruxism without any pain. Facial asymmetry and many dental problems such as midline deviation, "ground glass appearance" on the entire jaw, thinned cortical bone, loss of lamina dura and ectopic germs were found. Because of severely displaced tooth germs and FD affected jaw, there is a high possibility of malocclusion during mixed/permanent dentition. It is necessary to observe the eruption pattern periodically. If there are clinical symptoms like an abnormal eruption pattern, facial asymmetry or high caries susceptibility, appropriate interventions of dentist are required.

Preterm infants have higher possibility of undergoing endotracheal intubation after birth than normal children due to medical conditions. Developmental disturbances of primary incisors following intubation can occur as crown malformation, enamel defects, delayed eruption, displacement of dental follicle in crypt, groove formation of palate or alveolar ridge, acquired cleft palate, and dental arch distortion. This clinical report presents the effect of intubation on primary dentition of preterm infants. A 2-year-old girl with cerebral palsy and premature birth history visited our clinic with chief complaint of unerupted primary upper incisor. A 1-year-old boy with cerebral palsy, status epilepticus and premature birth history visited our clinic due to crown malformation. Developmental disturbances of primary incisors in these cases were not related to the patients' systemic disease, and there were no history of dental trauma. A long term endotracheal intubation prior to tooth eruption might have caused local trauma on alveolar ridge. It is very important to monitor dental problems of preterm infants who had experienced endotracheal intubation during neonatal period. Due to influences on both primary and permanent teeth, periodic re-evaluation of affected areas and establishment of comprehensive treatment plans are necessary.

Objectives: This study aimed to develop the CAMBRA-kids application for the systematic management of dental caries among preschoolers, activate the dental caries management system, and contribute to the dental caries management of preschoolers. Methods: The collected data were analyzed using R studio 1.2.1335 for Windows (RStudio Inc., Boston, MA, USA, 2018). Algorithm evaluation, heuristic evaluation and usability evaluation were analyzed using descriptive statistics. Results: Both expert evaluations of the application's algorithms were calculated as 100%, for proficiency and efficiency. The application worked well with the designed algorithms, the risk group level of participants was categorized appropriately, and the risk management method was guided properly according to the risk group level. Of the five problems presented in the heuristic evaluation, 'the lack of security' and 'the lack of information on oral health care' received 'high severity' scores. The usability evaluation of the application produces an overall score of 3.27. In the subscales (participation, functionality, aesthetics, and information) of the Mobile App Rating Scale (MARS), the 'participation' domain received the lowest score of 2.56 and the 'functional' domain received the highest score of 3.70. Conclusions: The CAMBRA-kids application is expected to be applied and used in the field of preschoolers' oral health care management, and to contribute to the prevention of dental caries of preschoolers by activating the dental caries management system using the application.

The purpose of this to inquire of the people who run a dental mechanical laboratory having troubles to manage and to find out the reform measures on the point at issue. With having done random sampling for the chiefs of dental mechanical labs across the nation, and then marking the analysis of the data for the survey, I came to a conclusion to be as follow. 1. The operating problems in dental mechanical laboratory in Korea is that it is too near at hand that the requested days for the manufacture of dental prosthesis appliances form dental clinics(45%)(P<0.01) 2. The problem of dental mechanic manpower was due to a small salary and inferior working environment(35% each)(P<0.01) 3. Some of them discount dental mechanical charges in manufacturing dental prosthesis appliances(36.7%)(P<0.01) 4. Many of them employed unlicensed dental technicians(61.7%)(P<0.01) As a counterplan for the aforementioned, I think that the whole dental mechanics should cooperate in breaking off the customary custom to allow a discount on the dental mechanical charges and readjust the dental mechanical charge to a realistic level so as to contribute to the development of the dental mechanical community and the vetterment of the public oral hygience.
