Background: Inferior alveolar nerve block (IANB) of the mandible is commonly used in the oral cavity as an anesthetic technique for dental procedures. This study evaluated the success rate of the first IANB administered by dental practitioners. Methods: Volunteer dental practitioners at Mahidol University who had never performed an INAB carried out 106 INAB procedures. The practitioners were divided into 12 groups with their advisors by randomized control trials. We recorded the success rate via pain visual analog scale (VAS) scores. Results: A large percentage of the dental practitioners (85.26%) used the standard method to locate the anatomical landmarks, injecting the local anesthetic at the correct position, with the barrel of the syringe parallel to the occlusal plane of the mandibular teeth. Further, 68.42% of the dental practitioners injected the local anesthetic on the right side by using the left index finger for retraction. The onset time was approximately 0-5 mins for nearly half of the dental practitioners (47.37% for subjective onset and 43.16% for objective onset), while the duration of the IANB was approximately 240-300 minutes (36.84%) after the initiation of numbness. Moreover, the VAS pain scores were $2.5{\pm}1.85$ and $2.1{\pm}1.8$ while injecting and delivering local anesthesia, respectively. Conclusions: The only recorded factor that affected the success of the local anesthetic was the administering practitioner. This reinforces the notion that local anesthesia administration is a technique-sensitive procedure.

Dental phobia is the most prevalent fear in all age groups, across gender, and in all countries. One of the primary identified sources is the fear of dental injections in the dental phobia or the high dental fear and anxiety groups. The purpose of this study was to clinically evaluate the computer controlled anesthetic device and to compare it with traditional methods of dental anesthetic delivery. Fifty(mean age : 25.6 yrs) systemically and periodontally healthy volunteers participated in this study. The subjects were given contralateral buccal and palatal injections. One side was injected with the computer-controlled anesthetic device with a microprocessor and an electric motor to precisely regulate flow rate during administration : The experimental group. The control side was injected with a standard manual syringe, in which flow rate and pressure are operator-dependent and can't be controlled accurately : The control group. The subjects described their perceived pain experiences with two subjective scales. The results of this study were as follows: 1. The computer-controlled anesthetic device was significantly less painful than conventional syringe injection 2. The female subjects reported more pain than the male subjects. But, there were no statistical differences. 3. The anesthetic effect of both methods did not show any difference. In this study, it may be concluded that pain levels decreased significantly when the computer-controlled anesthetic device was used.

The purpose of this study was to investigate the relation between and subjective instability pain behavior (SIPB) and physical instability test(PIT) according to the presence of characteristic past histories(CPH) in people with chronic low back pain(CLBP). Forty CLBP subjects participated in this study. The presence of four characteristics past histories(long term history, traumatic experience, sports activities, neurologic sign) were examined. According to presence number(PN) of CPH, subjects were divided into 5 groups[group 1(PN:0): n=8, group 2(PN:1): n=8, group 3(PN:2): n=8, group 4(PN:3): n=8, group 5(PN:4): n=8]. After 16 items were examined for the SIPBs, then Seven PITs were conducted, and the results were scored. The SIPBs and PITs were compared according to the presence numbers of CPH, and the relation between them was analyzed. There was a significant difference(p<.05) in both SIPB scores and PIT scores in the comparison of groups according to the presence number of CPH. There was high positive correlation between the presence numbers of CPH and SIPB score(r=.819, p=.000) and PIT score(r=.606, p=.000). Also, there was a correlation between SIPB score and PIT score(r=.571, p=.000). Based on the findings in the present study, the presence of three or more CPH in people with CLBP may be a useful variable in the diagnosis of lumbar instability. The combined findings of the three variables such as CPH, SIPB, and PIT can improve the accuracy of lumbar instability diagnosis.

Purpose: In this study, the changes in the shape of silicone hydrogel lenses, dryness of lens and objective/ subjective symptoms that could be induced by repeating dryness of lens and objective/subjective symptoms were investigated. Methods: After drying and rehydrating of silicone hydrogel lenses with different lens material and thickness for 4 times, their overall diameters and base curves were compared. Subjective symptoms, non-invasive tear break-up time (NIBUTs) and blinking rate were evaluated after wearing dehydrated silicone hydrogel lens. Results: Overall diameter and base curve increased in all tested silicone hydrogel lenses by repeating dryness and rehydration. The degree of change in over all diameter and base curve were variable on the material. There were irregular change of lens parameters in thicker lens. When the subjects wore silicone hydrogel lenses after drying and rehydrating, their NIBUTs were decreased and blink rates were increased regardless of lens material or thickness. In addition, repetitive drying of silicone hydrogel lenses affected the lens fitting. Therefore, subjective symptoms such as itching, pain, irritation, foreign body sensation, dryness tended to be increased. Conclusions: The results obtained from the study may suggest to develop durable silicone hydrogel contact lenses against dry environment since the changes in parameters of silicone hydrogel lens and the subjective discomfort were observed after repetitive drying and rehydration.
To evaluate the current indoor air quality condition of private academic facilities in Korea and investigate its association with subjective symptoms of student residing at the same academic facilities, air quality monitoring was carried out in total of 20 academic facilities located in Seoul, Daejon and Chungnam from the beginning of January to the end of April, 2009. To assess the air quality condition of academic facilities, 6 air pollutants with temperature and humidity were measured simultaneously inside and outside of academic facilities. The rate of exceeding the Indoor Air Quality (IAQ) guideline concentrations in 6 air pollutants were 5%, 85%, 15%, 5%, 10% and 30% for CO, $CO_2$, PM10, HCHO, TVOCs and TBC, respectively. A questionnaire on 16 subjective symptoms related to indoor air quality was given to 342 students who studied at the 20 academic facilities. The most frequent symptom of students was 'I feel easily tired or sleepy', and this was followed by 'I feel muscular pain or stiffness on shoulder, back and neck'. The association of net difference (subjective symptoms at the academic facility - subjective symptoms of the usual situation) with air pollutants was analyzed using spearman rank correlation. In logistic analysis using proportional odds method, the students whose indoor air concentration of HCHO was ${\geq}60{\mu}g/m^3$ hadsignificant odds of having more subjective symptoms of 'My eyes are dry or feel irritated or itching' (OR=5.026: CI=1.587-15.911), 'I feel easily tired or sleepy' (OR=2.956: CI=1.072-8.152), 'I lose my concentration and I feel my memory is falling' (OR=7.745: CI=1.938-30.955) and 'I feel dizzy' (OR=4.424: CI=1.292-15.149) than those of <$60{\mu}g/m^3$.
Purpose: To evaluate the effectiveness of temporomandibular joint (TMJ) disorder follow-up and determine the factors that affect the TMJ bone scan hot spot numerical value (bone scan value), and to compare this value to the diagnosis of patients with temporomandibular joint disorders (TMD), their treatment options, and the resolution of their symptoms. Materials and Methods: A retrospective cohort study was performed on 24 patients (four males, 20 females) who received TMD treatment in the Section of Dentistry, Seoul National University Bundang Hospital (Seongnam, Korea) from 2007 to 2014. An analysis of the significance test and correlation between TMD diagnosis, treatment options, a baseline the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) questionnaire, treatment before and after the clinical examination and subjective progress, and TMJ bone scan value change were completed by using SPSS version 12.0. Result: Although only 14 patients had bony factors that caused TMD, the average pre-treatment bone scan value of the all patients was $4.29{\pm}0.31$, which is higher than the finding for osteoarthritis (3.88), and reduced post-treatment bone scan value was found to be without a statistically significant difference (P=0.056). After the treatments, clinical symptoms in 18 patients disappeared, and six patients did not require additional treatment, although they still displayed subjective symptoms. It was observed that the higher the pre-treatment bone scan value, nonspecific physical symptoms, chronic pain index, characteristic pain intensity, disability score, were, the lower the post-treatment bone scan value was. And this reduced post-treatment bone scan value tendency was not shown with the pre-treatment depression index, but there was not a statistical difference. Conclusion: The post-treatment TMJ bone scan value tended to be insignificantly reduced in the 24 patients whose clinical symptoms were improved (P=0.056). Moreover, the TMJ bone scan value showed no relation to the TMD type or its related symptoms.
Treatments of severely incurved toenails cause anatomical changes and cosmetic problems, even though they provide adequate symptom relief. Incurved toenail patients treated with a K-D$^{(R)}$ (S&C Biotech, Seoul, South Korea) the new device for correcting curved nail deformity were investigated retrospectively. This study surveyed 12 patients(18 cases) who had been treated for severe ingrown toenails using K-D$^{(R)}$ from May 2008 to March 2009, and examined their subjective satisfaction before and after the treatment. The average age of the participants was 39 (ranging from 27 to 52), and 8 of them were male and 4 female. The treatment was applied after the patients were given a thorough explanation about the tool and the treatment, and questionnaire surveys were conducted before the treatment and after 3 months on the average from the treatment. In the survey, the respondents were asked about pain, restriction on activities, and the selection of shoes. For each item, symptoms with a given point were presented, and the respondents' scores were compared between the surveys before and after the treatment. According to the results of the questionnaire survey, pain increased from 14 out of 40 before the treatment to 39 after, activity restriction increased from 11 to 30, and shoe selection increased from 20 to 30. The average total score increased from 45 to 98, and this suggests a considerable enhancement in the patients' subjective satisfaction. The average period of the application of K-D$^{(R)}$ was $20.3{\pm}9.4$ days, and in all the cases, ingrown toenails were corrected within three weeks.
Purpose: To investigate the short term result of the first metatarsophalangeal arthrodesis for treating the hallux valgus deformity of rheumatoid arthritis, using a lag screw and dorsal mini-plate. Materials and Methods: From December 1999 to September 2001, The first metatarsophalangeal arthrodesis of 14 cases (9 patients) was underwent, using a lag screw and dorsal mini-plate. The follow-up period was averaged in 14.6 months. The subjective findings with respect to pain, functional aspect of ability to stand and walk, and to shoe-wearing were evaluated. The objective findings, such as the gross alignment and the radiological measurements for the hallux valgus angle, 1,2 intermetatarsal angle, and dorsiflexion angle were also studied. Results: After the arthrodesis of the first metatarsophalangeal joint, the subjective improvement in pain, function and alignment was graded as excellent in seven (50%) feet, good in seven (50%) feet, and fair or poor in none. The hallux valgus angle and 1,2 intermetatarsal angle were reduced from $44.1{\pm}7.1$ and $15.5{\pm}6.2$ degrees to $13.6{\pm}2.6$ and $10.2{\pm}2.2$ degrees respectively. The dorsiflexion angle was measured in $20.3{\pm}3.7$ degrees after the fusion. The radiological fusion was observed at average 8 weeks after the operation in all cases. The overall complication of the procedure was few, except the delayed wound healing in one. Conclusion: The arthrodesis of the first metatarsophalangeal joint using a lag screw and dorsal mini-plate was regarded as an excellent method of various operative modalities to correct the rheumatoid hallux valgus deformity.

Background: Although there have been multiple reports on surgical outcomes of superior labral anterior to posterior (SLAP) lesions in overhead athletes, only a few reports exist in the literature about the results of nonoperative treatment in elite (collegiate or professional) overhead athletes. To determine the clinical outcomes of nonoperative treatment of SLAP lesions in elite overhead athletes. Methods: Between January 2006 and December 2011, 69 patients were selected. Initial arthroscopic SLAP repair was performed in 19 patients and of the 50 patients who underwent nonsurgical treatment, such as range of motion gain and periscapular muscle strengthening, 14 patients were converted to surgical treatment; 5 patients were lost to follow-up. Medical records of 31 elite overhead athletes who underwent nonsurgical treatment were retrospectively reviewed. Four clinical outcome measures were used: visual analogue scale (VAS) for pain, VAS for satisfaction, American Shoulder and Elbow Surgeons (ASES) score, and subjective feeling of recovery. Results: The average follow-up period was 35.9 months (range, 24-62 months). The VAS for pain decreased from 6.5 to 2.2 (p<0.01) and VAS for satisfaction was 7.6. The ASES score increased from 54.1 to 85.9 (p<0.01). The overall average value of subjective feeling of recovery was 72%. Twenty-three out of 31 elite athletes (74.2%) returned to play after rehabilitation; these 23 athletes performed at the same or higher levels after rehabilitation. Conclusions: Nonsurgical treatment in elite overhead athletes with SLAP lesion should be considered as a treatment option.
Objective: This study examined a case in which insomnia and pain due to herniated intervertebral disks were improved by treatment with an oriental herbal and the administration of Uhwangchungsim-won. Case Summary: Three patients with insomnia diagnosed with herniated intervertebral disks were treated with a series of Korean medical therapies, including the herbal medication Uhwangchungsim-won, acupuncture, herbal acupuncture, and physical therapy. We used the Numerical Rating Scale (NRS) to measure subjective sleep states and the European Quality of Life Five Dimensions (EQ-5d) Scale to evaluate the therapeutic effect. Following treatment, subjective sleep states and the overall scores for pain had improved. Conclusion: The results indicate that Korean medical therapies with Uhwangchungsim-won have beneficial effects on insomnia for patients with herniated intervertebral disks.
