Whenever endodontic therapy is performed on mandibular posterior teeth, damage to the inferior alveolar nerve or any of its branches is possible. Acute periapical infection in mandibular posterior teeth may also sometimes disturb the normal functioning of the inferior alveolar nerve. The most common clinical manifestation of these insults is the paresthesia of the inferior alveolar nerve or mental nerve paresthesia. Paresthesia usually manifests as burning, prickling, tingling, numbness, itching or any deviation from normal sensation. Altered sensation and pain in the involved areas may interfere with speaking, eating, drinking, shaving, tooth brushing and other events of social interaction which will have a disturbing impact on the patient. Paresthesia can be short term, long term or even permanent. The duration of the paresthesia depends upon the extent of the nerve damage or persistence of the etiology. Permanent paresthesia is the result of nerve trunk laceration or actual total nerve damage. Paresthesia must be treated as soon as diagnosed to have better treatment outcomes. The present paper describes a case of mental nerve paresthesia arising after the start of the endodontic therapy in left mandibular first molar which was managed successfully by conservative treatment.

Bony exostosis, one of the osseous deformities, could act as a contributing factor of periodontal disease since it makes proper tooth brushing difficult and causes traumatic ulcer. The purpose of this case report is to show improvement of periodontal health by removal of bony exostoses and creation of physiologic osseous form. A 58 year-old female patient with recurrent ulcer and pain on bony exostoses located on left maxillary palatal area and both mandibular buccal areas was treated. Exostoses were removed and physiologically positive osseous form was created following vertical grooving, radicular blending, flattening interproximal bone and gradualizing marginal bone. The patient showed no further recurring traumatic ulcer and bone exposure. Moreover, periodontal pocket was eliminated and food impaction was decreased. In conclusion, periodontal health could be achieved through removal of multiple bony exostoses and development of ideal osseous form.

The objective of this study was to assess oral health status such as prevalence of dental caries, gingivitis and other combined disorder, orofacial dysfunction in patients with cerebral palsy(CP), as well as the state of tooth brushing, possibility of dental treatment. Sixty-six subjects with CP aged 9 to 37 years were included in the study. Clinical caries status(DMFT index) and other data were evaluated and statistically analyzed using SPSS program (SPSS 17.0). The results were as follows: The DMFT index and prevalence of gingivitis of study subjects were 2.82(male), 3.33(female) and 89%, respectively. DMFT index classified into four groups according to age as follows: DMFT index were 1.14(ages 6-11), 1.40(ages 12-14), 2.16(ages 15-24), 4.15(ages 25-37). In addition to the physical disorder, speech difficulty(86%), epilepsy(35%) and visual impairment(14%) were associated and the epilepsy medication was the most common medication. And orofacial dysfunction such as the eating difficulties(79%), drooling(36%), swallowing disorder(30%), breathing difficulty(15%), bruxism(30%) and snoring(33%) was shown. Most people with cerebral palsy can't brush alone and didn't use oral care adjunctive supplies. Moreover, Fifty-nine percent of them were noncooperative to dental treatment.

A non-carious cervical lesion(NCCL) is the loss of tooth structure at the cementoenamel junction level that is unrelated to dental caries. This study was to evaluate the occlusal and periodontal status of teeth with non-carious cervical lesions. We evaluated 105 teeth with non-carious cervical lesions in 35 subjects aged 38-75 years and characterized them based on the shape and dimension, plaque retention, bleeding on probing(BOP), probing pocket depth(PPD), occlusal status, brushing type, hypersensitivity and wear facet. The results of this study were as follows 1. No significant association was observed between cervical lesions and occlusal contact in lateral excursions. 2. No significant difference occurred in plaque retention, PPD, BOP between teeth with and without cervical lesions. 3. Test teeth had a significantly higher percentage of hypersensitivity and occlusal wear facet than teeth without cervical lesions. 4. Wedge shaped lesions had a significantly higher percentage of plaque than saucer shaped lesions. 5. Teeth with plaque were found to have significantly deeper PPD than teeth without plaque retention in cervical regions. 6. Teeth with occlusal contacts were found to have significantly deeper PPD than teeth without occlusal contacts. 7. No significant association was observed between cervical lesions and PPD independent of plaque retention and occlusal contacts Although more knowledge is necessary, our results suggest that occlusal contact and bacterial plaque may influence on periodontal tissue, but NCCL is not directly associated with periodontal health

The study surveyed 1,127 mothers whose children aged 3 to 5 went to 25 randomly selected kindergartens, which were located in Busan Metropolitan City and the adjacent Gimhae City, and analyzed the preventive health behaviors on their children and the condition of home health education on their children. As the compulsory kindergarten education will e to be implemented within 4 years, this study aimed to draw up the rudimentary material for health education at kindergartens. The study results are summed up as follows: 1. Mothers' awareness of health-related attitude and behavioral level for their children at kindergarten: 1) The general health condition of the children, which mothers are aware of, was that they were healthy on the whole. As their children becomes older, the income level of the parents is lower, and mothers have lower level of educational standard, the health condition of the children was found a little lower. 2) In terms of mothers' recognition of the practice level of preventive health behaviors, the items such as going to bed regularly, washing hands and feet well, and having meals regularly were high in the practice level, while exercise and tooth-brushing were not practiced well. 2. The condition of mothers' health education of their children: 1) It was found that washing hands and feet, restriction of overeating and preference for specific kinds of food, guidance on regular sleep and regular meal were practiced well among items of home health education targeting kindergarten children. 2) Mothers have obtained information on family health from printed matter such as newspaper or magazine rather than the visual media. 3) From the cross analysis of mothers' health education on children and children's health behaviors, as the standard of education of mothers was higher, so was the level of preventive health behaviors of children. 3. From the result of multi regression analysis of the factors influencing the preventive hygiene of kindergarten children, it was found that as the home health education level was higher, so was the health behavior of children. On the other hand, as the mothers were older, the health behavior of children became lower.

The purpose of this study was to examine association between oral health status and perceived general health symptom. We analyzed 14,231 subjects who participated in Korea National Health and Nutrition Examination Survey (2007~2009). All individuals were examined by a questionnaire about socioeconomic history, smoking and drinking habit, the frequency of daily tooth brushing, the presence of regular dental visit, and EuroQol-5D. Dental survey was conducted to find the decayed, missing, and filled teeth (DMFT) index and community periodontal index. Subjects with perceived problem with mobility had higher DMFT index (odds ratio, 1.18, p<0.001). Subjects with with perceived problem with pain/discomfort had higher DMFT index (odds ratio, 1.16, p<0.001). Self-rating general health symptom was not associated with periodontitis (p>0.05). Perceived general health was associated with DMFT index. It is recommendable that we can use the perceived general health to predict oral health status.

Background: Smartphones are a modern necessity. While they are convenient to use, smartphones also have side effects such as addiction. This study assessed the relationship between smartphone use, a part of everyday life in modern society, and oral health. Methods: An analysis was conducted using 2017 Korea Youth Risk Behavior Web-based Survey data. The propensity score estimation algorithm used logistic regression and 1:1 matching algorithm using nearest-neighbor matching. After matching, a total of 15,032 participants were classified into two groups containing 7,516 teenagers each who did and did not use smartphones, respectively. Results: Comparison of oral health behaviors according to smartphone use revealed a statistically significant difference in the frequency of tooth brushing per day, use of oral hygiene products, intake of foods harmful to oral health, and experience of oral health education (p<0.05). The factors affecting oral pain experience of adolescents were examined. Compared to male participants, female participants had an odds ratio of 1.627 for oral pain (p<0.05). According to the household income level, compared to the group with higher income, the group with lower income showed higher oral pain experience (p<0.05). Oral pain experience was 1.601 times more frequent among teenagers using smartphones (p<0.05). Conclusion: The results of this study indicated that use of smartphones by adolescents affected their oral health. These findings indicate the need for improved oral health management through the use of effective school oral health programs and individual counseling by oral health professionals, promotion of information dissemination through public media, and development of prevention strategies.

Glanzmann's thrombasthenia is a Qualitative platelet disorder characterized by a deficiency in the platelet membrane glycoproteins IIb/IIIa. It belongs to a group of hereditary platelet disorders typified by normal platelet numbers and a prolonged bleeding time. The severity of bleeding does not correlate with the severity of the platelet glycoprotein IIb/IIIa a abnormality. The present case report describes the periodontal treatment of a patient with Glanzmann's thrombasthenia. A 30-year-old female with a history of Glanzmann's thrombasthenia was referred for gingival bleeding on tooth brushing and discomforts in #38 area. The periodontal finding revealed a diagnosis of localized slight adult periodontitis. Root planing and extraction of #38 was performed under 12 pack of platelets transfusion and digital compression was done for hemostasis. The gingival bleeding ceased within a day in maxilla and 2 days later in mandible. 42 pack of platelets was administered for 3 days of post-treatment and for iron-deficiency anemia 3 pack of RBCs was transfused 2 days later. 1 week later the inflammation in gingiva disappeared and gingival stippling appeared. The clinical result we got was good and in such a medically compromised patient it is an ability to maintain a proper oral hygiene that is essential both for oral and systemic health.
