The canalis sinuosus (CS) and its accessory canals (ACs) are anatomical structures in the anterior maxilla. These structures are often neglected when planning implant surgery because their clinical significance is still not well-defined. After a retrospective evaluation of 194 patients rehabilitated with dental implants in the anterior maxilla, 3 patients were identified who presented unexpected chronic neurosensory disturbances without any clinical signs supportive of implant failure. Tomographic assessment using cone-beam computed tomography (CBCT) revealed the invasion of the CS and ACs by dental implants, which appeared to explain the patients' symptoms. The purpose of this report was to familiarize practicing dentists and specialists with the CS and its ACs. Unanticipated neurosensory symptoms after implant placement in the anterior maxilla justify the use of CBCT to rule out an injury to this neurovascular bundle.

Objectives : This study was purposed to estimate prevalence of upper extremity musculoskeletal symptoms, level of occupational stress and their relationship among dental hygienists. Methods : This questionnaire study was performed during May to October 2010 with 317 dental hygienists worked in Busan and Gyeongsangnam-do recruited as study population. The occupational stress and upper extremity musculoskeletal symptoms were accessed using questionnaire of the Korean Occupational Stress Scale and musculoskeletal symptoms from the Korea Occupational Safety Health Agency. Data analysis was performed with the descriptive analysis, chi-square test, and multiple logistic regression analysis using SPSS(ver 19.0K)program. Results : The prevalence of upper extremity musculoskeletal symptoms and the level of occupational stress were 79.2% and $52.67{\pm}4.86$ in dental hygienists. By multiple logistic regression analysis, job insecurity(OR=2.86, 95% CI: 1.38-5.94 in stress high risk group; reference-stress low risk group) and organizational system(OR=3.32, 95% CI: 1.55-7.08 in stress high risk group; reference-stress low risk group) were associated with upper extremity musculoskeletal symptoms in dental hygienists. Conclusions : The overall prevalence of upper extremity musculoskeletal symptoms and level of occupational stress in dental hygienists were relatively high and some sub-scales of occupational stress were related with upper extremity musculoskeletal symptoms. Not only previously reported risk factors of musculoskeletal symptoms but also occupational stress should consider to prevent and improve upper extremity musculoskeletal symptoms in dental hygienists.

Objectives: The purpose of the study was to find out dental caries and periodontal disease based on oral healthcare of adults in Busan. This study will provide the preventive oral healthcare for the periodontal diseases and dental caries. Methods: The study subjects were 369 people from the regular dental health checkup in the general hospital in Busan. After receiving informed consent, a self-reported questionnaire was completed from October 1, 2014 to January 31, 2015. The questionnaire consisted of dental caries and periodontal diseases by direct examination and toothbrushing method. Data were analyzed by ${\chi}^2$ test, Fisher's exact test, and Pearson's correlation. Results: In the morbidity of dental caries and periodontal diseases, the dental caries was most common in those having restored teeth(236 subjects, 64%), while periodontal diseases were found in mild cases of gingival inflammation in 285 subjects(77.2%), and mild cases of dental calculus in 274 subjects(73.4%). Most of the respondents replied that they did not have systemic disease or oral health related symptoms. According to toothbrushing pattern, dental caries experiences were most common in those having less frequent toothbrushing less than 3 minutes and no tongue brushing. The outbreak of dental caries was more common in 5 times than 3 to 4 times a day. Conclusions: The education of the right toothbrushing method and use of dental floss is the most important prevention of dental caries and periodontal disease in the adults.

The purposes of this study were to investigate the oral health status of the disabled children attending special schools in Seoul and Gyeonggi area, which were to collect baseline data for set up a oral health center in special schools. The study group comprised 915 disabled children aged 12~15 year. They were examined clinically and surveyed on 4 oral health related characteristics according to the type and level of disabilities The results may be summarized as follows: 1. DMFT index was the highest in children with crippled disorder. The plaque control was more required to the children with mental retardation or developmental disorder other than another types of disabilities. 2. About one third of the children with mental retardation or developmental disorder had their teeth brushed at least 3 times daily without any help. Over the half of the children with crippled disorder had their teeth brushed 2 times daily, 33.3% were independent and 38.9% totally dependent on help from others. 3. The more level of disabilities was higher, the more frequency of tooth brushing was lower and degree of dependance of the tooth brushing was higher. 4. There was tendency to visit to dental office more frequently for relief of dental symptoms in children with crippled disorder 5. The inability to call for help from others was the major barrier to dental care for the disabled.

For the purpose of the curative effects of oral D-penicillamine in lead poisoning, D-penicillamine was orally administered to 7 lead poisoned workers which were employed in glaze product industry dealing with the lead oxide ($Pb_3O_4$). The doses of D-penicillamine was 1,200mg per day which was administered by oral 7days schedules, taking for 5 days and stopping for the following 2days, repeatedly during 3 months period. (All the poisoned workers started working again in that industry after 1 month treatment, and were treated by oral D-penicillamine for 2 months still being exposed to contaminated environment.) In order to evaluate the curative effects of D-penicillamine, 10gm of whole blood and 24 hours urine were collected every 14 days during the curative period for laboratory analysis(hemoglobin, blood lead, urine $\sigma$-aminolevulinic acid, urine coproporphyrin, and urine lead levels) with the observation of the clinical symptoms. The results were as follows; 1. Oral D-penicillamine effected good curative results as that hemoglobin, blood lead, urine $\sigma$-aminolevulinic acid, and urine coproporphyrin levels were decreased below the critical level within 1 month treatment. 2. After re-exposure, oral D-penicillamine effected to some extent as that urine lead level was decreased below the critical level after 3 months treatment with disappearence of the clinical symptoms after 2 months treatment. However, the curative effects of oral D-penicillamine in the lead exposure state is questionable since increasement of blood lead level and remarkable decreasement of urine lead level after 3 months treatment can be observed.
