Purpose: The aim of this clinical study was to evaluate the efficacy and safety of a self - applied paint - on whitening gel combined with wrap to increase the effect of a whitening gel and minimize gingival irritation. Materials and Methods: Ninety adult volunteers were randomly treated to a control group and two experimental groups using whitening gel containing 2.8% and 3.0% hydrogen peroxide for 30 persons each. They had used the wrap and whitening gel on maxillary 4 anterior teeth for 30 minutes per day during 2 weeks. Whitening tooth color response was measured by VITA shade guide and ShadeEye $NCC^{(R)}$. And side effects were assessed from interview and intraoral examination. The efficacy and safety evaluations were statistically analyzed. Results: In the evaluation with VITA shade guide, there was significantly the whitening effect in experimental groups compared with the control group. In the evaluation with ShadeEye $NCC^{(R)}$, the 3.0% experimental group showed significantly the whitening effect compared to the control group and the 2.8% experimental group (P < 0.05). There were some complaints of minor side effects, but there did not find abnormal symptoms of the gingival stimulation in all groups. Conclusion: A self - applied paint - on whitening gel combined with wrap can be used as a useful self-whitening material because the whitening effect increases as the concentration of hydrogen peroxide from 2.8% to 3.0% and also no significant side effects are observed.

Glanzmann's thrombasthenia (GT) is a rare, autosomal recessive inherited congenital disorder, characterized by impaired blood coagulation due to platelet dysfunction. It was first reported by the pediatrician Glanzmann in 1918. GT affects both males and females, and it is more common in regions of the Middle East, India, and France, where intermarriage is common. It has an incidence of about 1 in 1,000,000 people. In South Korea, according to the Division of Rare Diseases, Korea Centers for Disease Control and Prevention, around 200 cases have been reported in 2018. Clinical symptoms include petechia, ecchymosis, epistaxis, and gingival bleeding. The spontaneous loss of deciduous teeth can result in excessive bleeding with that blood transfusion should be considered. Preventing hemorrhages and hemostasis are most important factors in dental treatment. Local bleeding can be controlled by compression, but platelet transfusion can be required by prolonged bleeding. Pediatric dentists can minimize the gingival bleeding by control of the oral hygiene to prevent gingivitis and dental caries. The importance of oral hygiene and periodic recall check-up should be emphasized. During dental treatment, the examination and the treatment plan of patient should be modified to prevention of hemorrhages carefully. A 6-year-old girl with GT was referred for the treatment of dental caries, and resin restoration was performed under nitrous oxide inhalation sedation. After treatment, compression was required for the bleeding control.

The purpose of this study was to help improve oral health care planning for the elderly in an effort to promote the oral health of elderly people in preparation for aging society. The subjects in this study were 200 elderly people who were selected by random sampling from senior centers in Seoul. An interview was conducted to gather data from June to September 2008, and the data collected were analyzed.: 1. The mean number of residual tooth was 13.71. 2. Concerning connections between gender and subjective oral symptoms, gender had a statistically significant relationship to temporomandibular joint dysfunction(p=0.000), dry mouth(p=0.001) and halitosis(p=0.006). The men underwent more oral symptoms than the women. 3. As for the relationship of mastication(p=0.000), oral pain(p=0.010), temporomandibular joint dysfunction(p=0.010) and dry mouth(p=0.001) to subjective oral health state, the elderly people who were not in a good oral health suffered more oral symptoms, and the gap between them and the others was statistically significant. 4. A larger number of tooth led to less mastication difficulties, less dry mouth and more gingival diseases, and the relationship between the factors was statistically significant. A better oral health state led to less mastication difficulties, less oral pain, less dry mouth and less bad breath, and the relationship between the factors was statistically significant. Through this study the oral health the elderly people perceive wss concerned with oral symptom, and the number of residual teeth also had links to subjective oral symptoms. Therefore, to maintain original teeth of the elderly people, the management system of oral health and the education program for oral health in order to prevent disease relateded with oral and enhance the perception standard of oral state are indispensably necessary to the elderly people.

The purpose of this study was to observe the potentiality of a mixture of antibiotics to relieve the endodontic and periapical infections in primary teeth. A mixture of metronidazole, ciprofloxacin, and minocyclin in distilled water or in a root canal sealer were used to disinfect the infected endodontic and periapical lesions. For application of this mixture, medication cavities were prepared at orifices of root canals by using the $Fissurotomy^{(R)}$ burs(S S White, USA). The cavities and bottom of pulp chamber were filled with antibiotics mixture. In this cases, clinical symptoms were improved following a single application of that mixture. Gingival swelling, pain, and fistulae were disappeared within a week. More long term evaluation will be needed. Although there were no reports of side effects, care should be taken if children are sensitive to antibiotics. Within the limitations of this case, the mixture of 3 antibiotics provided an excellent improvement in treatment of infected primary teeth under the physiologic root resorption.

Vitamin D-resistant rickets(VDRR) is hereditary disease manifesting marked hypophosphatemia caused by renal tubular loss of phosphate into urine and an associated decrease in the calcium and phosphorous ion product. VDRR is identified by clinical symptoms, such as in the limbs, gait disturbance, dwarfism, familial occurrence, bowlegs, and knock-knees, as well as by laboratory findings. Dental findings are enlarged chambers and extension of the pulp horns into the cusp tips in both the primary and the permanent dentition in contrast to the vitamin D-deficient rickets. The major oral manifestations are multiple spontaneous abscesses in a caries-free dentition. We reported the clinical features and treatment of a 6-year-old boy with vitamin D-resistant rickets referred to the department of pediatric dentistry in Kyung Hee University for multiple spontaneous periapical abscesses and gingival fistula without severe dental caries.
