The purpose of this study was to collect the basic data about oral health status of residentsin Chollabuk-do Province of Korea. At this province 11 sampling areas were chosen by Board of National Statistics. 5 areas were city areas including capital city of Chollabuk-do and 6 areas were rural ateas. The number of total sampling person was 676 adults aged 18 years old and above. The survey was conducted by individual home-visiting method. The contents of survey were status and need of dental prosthetics. The data were collected and analyzed by SPSS/PC. The obtained results were as follows; 1. The rate of persons wearing any dental prosthetic (fixed and removable partial denture and/or complete denture)was rapidly increased after 35years old. 2. The rate of persons wearing any dental prosthetics was 65.8% at upper jaw and 60.1% at lower jaw in the age group from 65 to74 year old, but 49.0% at upper jaw and 42.9% at lower jaw in the age group more than 75year old. 3. The rate of persons needing complete denture was 8.6% at upper jaw and 5.5% at lower jaw in the age group from 65 to 74year old, but 28.6% at upper jaw and 24.5% at lower jaw in the group more than 75year old.

<P>Congenital cytomegalovirus (cCMV) infection is a common congenital infection that causes sensorineural hearing loss (SNHL). Despite its substantial impact on public health and cost burden, epidemiology and clinical features of CMV-related SNHL have never been reported in the Korean populations. This study investigated the detailed audiologic phenotypes of cCMV infection to see if a specific SNHL pattern is associated with a particular clinical setting. A total of 38 patients with cCMV infection were studied retrospectively. Patients were classified into three groups with distinct demographics: clinically driven diagnosis (n=17), routine newborn CMV screening according to the NICU protocols (n=10), or referral to ENT for cochlear implant (CI) (n=11). The incidence of cCMV infection was 3.6%, showing 33.3% of SNHL among cCMV patients, 38% of asymmetric hearing loss, 29% of late-onset hearing loss, and diverse severity spectrum in patients with CMV-related SNHL. CI recipients with CMV-related SNHL showed a significantly improved speech perception. Surprisingly, in 36.4 % of CI implantees, initial audiological manifestation was significant asymmetry of hearing thresholds between both ears, with better ear retaining significant residual hearing up to 50dB. CMV turns out to be a significant etiology of SNHL, first to date reported in the Korean pediatric population. Analysis of audiologic phenotypes showed a very wide spectrum of SNHL and favorable CI outcomes in case of profound deafness. Especially for the patients with asymmetric hearing loss, close surveillance of hearing should be warranted and CI could be considered on the worse side first, based on the observation of rapid progression to profound deafness of better side.</P>

Kim, Bong Jik,Jung, Sung-Do,Lee, Hyun-Ju,Jung, Jae Yun,Suh, Myung-Whan Lippincott Williams Wilkins 2015 Otology & Neurotology Vol.36 No.3

OBJECTIVE: The aims of the study are to investigate the effect of hearing loss, age, and gender on the outcome of the cochlear hydrops analysis masking procedure (CHAMP) and to assess the clinical utility of CHAMP for the diagnosis of Ménière’s disease (MD). STUDY DESIGN: Prospective observational study. SETTING: Otolaryngology department of a tertiary referral hospital. PATIENTS: We recruited MD patients (MD, 12 subjects) and hearing loss patients (HL, 10 subjects). Control subjects (NC, 43 subjects) were matched for gender and age. INTERVENTION: CHAMP was performed in the patients and control subjects. MAIN OUTCOME MEASURE: The mean difference in latency between the wave V for the click alone response and wave V for the 0.5-kHz high-pass masking noise condition was compared among groups, and the effects of gender and age on the results were analyzed in the NC group. RESULTS: Both the MD group and the HL group had a smaller difference in latency compared to the NC group. The MD group and HL group showed no significant difference in latency. In the NC group, there were no significant differences in latency depending on gender and age. CONCLUSIONS: Hearing level seems to significantly affect the CHAMP results, making it unreliable to differentiate between MD patients and non-MD hearing loss patients. Therefore, the diagnostic value of CHAMP might be limited in MD.

The author studied the prevalence and sites of orofacial pain during the latest 6 months, and psychologic symptoms under the emotional stress through SCL-90-R in thirty-five dental students(nineteen men and sixteen women) of school of Dentistry, Chonbuk National University. 26 students(74.3%), 12 men and 14 women, experienced the orofacial pain; headache, toothache, facial & buccal pain, TMJ pain and intraoral pain were occurred in 51.4%, 37.1%, 25.7%, 17.1% and 17.1% respectively. In psychological scores in before-, during- and after examination, there was no significant difference between men and women. On the other hand, when these scores were compared each other in one group with orofacial pain experience and the other group without pain experience, the former showed significantly higher values in somatization, depression, hostility, and paranoid ideation dimension before examination, interpersonal sensitivity and anxiety dimension during examination, and somatization dimension after examination than those of the later group(P<0.05). The changes of psychologic symptoms in before-, during-, and after examination were observed in one group with pain experience and the other group without pain experience, respectively; in the former group the significantly higher values of anxiety dimension in during examination than after examination, and the significantly higher values of interpersonal sensitivity dimension in before examination than after examination(P<0.05) were evaluated.

<P><B>Abstract</B></P> <P><B>Objectives</B></P> <P>The central auditory pathway matures through sensory experiences and it is known that sensory experiences during periods called critical periods exert an important influence on brain development. The present study aimed to investigate whether temporary auditory deprivation during critical periods (CPs) could have a detrimental effect on the development of auditory temporal processing.</P> <P><B>Materials and methods</B></P> <P>Twelve neonatal rats were randomly assigned to control and study groups; Study group experienced temporary (18–20 days) auditory deprivation during CPs (Early deprivation study group). Outcome measures included changes in auditory brainstem response (ABR), gap prepulse inhibition of the acoustic startle reflex (GPIAS), and gap detection threshold (GDT). To further delineate the specific role of CPs in the outcome measures above, the same paradigm was applied in adult rats (Late deprivation group) and the findings were compared with those of the neonatal rats.</P> <P><B>Results</B></P> <P>Soon after the restoration of hearing, early deprivation study animals showed a significantly lower GPIAS at intermediate gap durations and a larger GDT than early deprivation controls, but these differences became insignificant after subsequent auditory inputs. Additionally, the ABR results showed significantly delayed latencies of waves IV, V, and interpeak latencies of wave I-III and wave I-V in study group. Late deprivation group didn't exhibit any deterioration in temporal processing following sensory deprivation.</P> <P><B>Conclusion</B></P> <P>Taken together, the present results suggest that transient auditory deprivation during CPs might cause reversible disruptions in the development of temporal processing.</P>

Jung, Won,Suh, Bong-Jik Korean Academy of Orofacial Pain and Oral Medicine 2018 Journal of Oral Medicine and Pain Vol.43 No.4

Purpose: Age estimation is often used in the identification of living persons. Various methods are used for age estimation using teeth, and there are many studies on the methodology. But the study of changes in the social aspects of age estimation with the passage of times is still insufficient. Therefore, the purpose of this study is to analyze the age estimation cases in the social aspects and to investigate the changes of age estimation cases in Jeollabuk-do. Methods: From January 2008 to December 2015, 76 cases of age estimation were collected. The collected data were organized and analyzed. The distribution of patients by age and year, the difference between alleged and registered age, the purpose of age estimation, and regional distribution were examined. In addition, we compared the previous study which analyzed the age estimation cases in Jeollabuk-do from 2000 to 2007. Results: According to the distribution by age, the age distribution was the largest in the 50s and 60s, with 69.8%. The most reason to correct age was related to welfare benefits (38.2%), and most of the people who corrected for welfare benefits were over 50 years old. The age correction for purpose of welfare benefits existed every year during the study period. As the result of comparison with previous study, total number of age estimation cases was decreased very sharply, and distribution by age group was also changed. Conclusions: Changes in age estimation cases were observed when compared to the previous study. A significant decrease in the total number of age estimation cases was observed, but the number of age estimation in the 50s did not decrease. Although the total number of age estimation requests decreases, age estimation in the elderly are likely to persist. Thus, it is necessary to study new age estimation methods suitable for the elderly.

Jin, Jung-Yong,Suh, Bong-Jik,Lee, Kyung-Eun Korean Academy of Orofacial Pain and Oral Medicine 2016 Journal of Oral Medicine and Pain Vol.41 No.3

Facial abscess is a suppurative condition that is caused by infection and that its infected materials built up within the loose connective tissues or a fascial space of the head and neck. Facial abscess should be treated with a caution since it can make threat to patient's life. When pus collects near masticatory muscles, it may lead to masticatory muscle disorder reducing the range of mouth opening and the mobility of jaw. The authors review an uncommon case of facial abscess which occurred in temporal muscle and induced mouth opening limitation.

Objective : This study was to estimate the prevalence of and identify the predisposing risk factors of delirium and to determine the effect of delirium on the prognosis, especially death in burn patients. Method : The study was completed by thorough examination of medical records, with additional confirmation, of the 245 patients who were admitted to the Burn ICU in Burn treatment center of Hangang Sacred Heart Hospital during last one year (Jan. 1. 1998-Dec. 31. 1998). Delirium was retrospectively diagnosed according to DSM-IV. Only when disturbance of consciousness and attention, cognitive dysfunction –especially disorientation–, or perceptual disturbance were observed, diagnosis of delirium were given. Final outcome such as death was discriminated through examination of medical records or question to those who knew the patient. Result : One year prevalence of delirium in burn patients is 34.4%. Statistically significant predisposing risk factors of delirium were five;Age 65 and over (OR=45.51, 95% CI : 6.07-341.11), burn size over 60% of total body surface (OR=6.48, 95% CI : 3.16-13.28), current psychiatric disorder (OR=6.81, 95% CI : 1.42-32.57), current medical disease (OR=3.00, 95% CI : 1.40-6.45), alcohol abuse (OR=3.17, 95% CI : 1.07-9.43) Statistically significant deathrelated risk factors were three;burn size over 60% of total body surface (OR=4.58, 95% CI : 2.00-10.46), delirium (OR=2.94, 95% CI : 1.25-6.94), current psychiatric disorder (OR=4.09,95% CI : 1.05-15.87). Aging is not the death-related factor in this study. Conclusion : Three factors, such as delirium, organic brain damage, and burn size over 60% of total body surface may predict higher risk of death in burn patients.
