  • Objective: The purposes of this study were 1) to classify lingual dental arch form types based on the lingual bracket points and 2) to provide a new lingual arch form template based on this classification for clinical application through the analysis of three-dimensional virtual models of normal occlusion sample. Methods: Maxillary and mandibular casts of 115 young adults with normal occlusion were scanned in their occluded positions and lingual bracket points were digitized on the virtual models by using Rapidform 2006 software. Sixty-eight cases (dataset 1) were used in K-means cluster analysis to classify arch forms with intercanine, interpremolar and intermolar widths and width/depth ratios as determinants. The best-fit curves of the mean arch forms were generated. The remaining cases (dataset 2) were mapped into the obtained clusters and a multivariate test was performed to assess the differences between the clusters. Results: Four-cluster classification demonstrated maximum inter-cluster distance. Wide, narrow, tapering, and ovoid types were described according to the intercanine and intermolar widths and their best-fit curves were depicted. No significant differences in arch depths existed among the clusters. Strong to moderate correlations were found between maxillary and mandibular arch widths. Conclusions: Lingual arch forms have been classified into 4 types based on their anterior and posterior dimensions. A template of the 4 arch forms has been depicted. Three-dimensional analysis of the lingual bracket points provides more accurate identification of arch form and, consequently, archwire selection.

  • Objectives: The purpose of this study is to analyze the factors affecting the self-perceived halitosis of adults and to utilize them as basic data for the development of prevention and management program to reduce of self-perceived halitosis. Methods: A questionnaire survey of 301 adults in their 20s and 50s living in Gwangju and Jeonnam selected by convenience sampling from July 1, 2017 to August 31, 2017 was conducted to investigate oral health status and behavior, fatigue and perceived stress. Statistical analysis was performed using frequency analysis, independent t-test, one way ANOVA, Pearson's correlation analysis, and multiple regression analysis. Results: The degree of self-perceived halitosis was higher in married (2.51) and unemployed (2.71), with tongue brushing (2.68), intention to participate in halitosis education (2.57), taking medication (2.73), coated tongue (2.82) and there was both otolaryngology and gastrointestinal disease (2.72) and periodontal disease (2.89) (p<0.05). Fatigue (${\beta}=0.237$), periodontal disease (${\beta}=0.196$), and coated tongue (${\beta}=0.237$) affect the self-perceived halitosis (p<0.001). Conclusions: The self-perceived halitosis in adults was correlated with fatigue and perceived stress. Also fatigue, periodontal disease, coated tongue factors were analyzed as factors influencing self-perceived halitosis. Additional studies such as prevention and management of periodontal disease and coated tongue, which is a factor of self-perceived halitosis in adults, and development of programs to reduce self-perceived halitosis for fatigue management, which is an external factor, are necessary.

  • Objective: This study aimed to (1) evaluate the effects of maxillary second and third molar eruption status on the distalization of first molars with a modified palatal anchorage plate (MPAP), and (2) compare the results to the outcomes of the use of a pendulum and that of a headgear using three-dimensional finite element analysis. Methods: Three eruption stages were established: an erupting second molar at the cervical one-third of the first molar root (Stage 1), a fully erupted second molar (Stage 2), and an erupting third molar at the cervical one-third of the second molar root (Stage 3). Retraction forces were applied via three anchorage appliance models: an MPAP with bracket and archwire, a bone-anchored pendulum appliance, and cervical-pull headgear. Results: An MPAP showed greater root movement of the first molar than crown movement, and this was more noticeable in Stages 2 and 3. With the other devices, the first molar showed distal tipping. Transversely, the first molar had mesial-out rotation with headgear and mesial-in rotation with the other devices. Vertically, the first molar was intruded with an MPAP, and extruded with the other appliances. Conclusions: The second molar eruption stage had an effect on molar distalization, but the third molar follicle had no effect. The application of an MPAP may be an effective treatment option for maxillary molar distalization.

  • Most dentists are very interested in laser therapy on the intraoral soft tissue lesions because they want to accomplish the analgesic and aseptic surgery with little or no bleeding. In order to determine the difference of pain threshold according to different gingival tissues with or without inflammation, 25 patients with inflammatory periodontal disease and 10 volunteers with good general and oral health were selected as the inflamed group and the normal group, respectively. Interdental papilla, marginal gingiva, attached gingiva, and alveolar mucosa were irradiated by the contact delivery($300{\mu]m$ fiber optic, for 5 seconds) of a pulsed Nd:YAG laser(EN.EL.EN06O, Italy). And the laser power was gradually increased from 0.5W by the increment of 0.1W. The highest laser power was recorded as the first painful power when the painful gesture was recognized at first. The difference of the first painful power of laser according to different gingival tissues with or without inflammation was statistically analyzed by paired t-test in MICROSTAT program. Following results were obtained: 1. In the comparison related with the inflammation, the first painful power was significantly lower in the inflamed group than in the normal group, regardless of interdental papilla and marginal gingiva(p<0.05). 2. In the comparison related with the tissue structure, the first painful. power was significantly lower in alveolar mucosa than in attached gingiva(p<0.05). The results suggest that, for the painless therapy by a pulsed-Nd:YAG laser irradiation, the laser surgery over 2.0W of power should be necessarily accomplished under the local anethesia, and the local anesthesia should be considered according to the degree of inflammation, the tissue structure, and the purpose of laser therapy.

  • 2013년, 치과위생사 역사의 100주년을 맞이하였다. 1913년, Dr. Fones가 Bridgeport Junior College에 2년 과정의 치위생교육프로그램을 개설하며, 구강간호가 아닌 구강질환의 예방과 보건학을 전문으로 하는 '치과위생사' 라는 직종명칭을 사용한 것이 그 시초다. 미국에서 최초로 치과위생사 제도를 최초로 도입한 만큼, 미국치과위생사의 발전과정을 되짚어 보는 것은 국제적인 치위생계 발전과정을 확인하고, 각국의 제도를 비교할 수 있는 근간이 될 것이다. 이 연구는 지난 100년간 미국치과위생사가 전문직 역할을 수립해 나가는 과정을 '치과위생사 조직의 발전과정', '치위생학 교육제도의 발전과정', '치과위생사 면허 및 관련 자격제도의 발전과정', '치과위생사 관련 법령과 윤리' 및 '미국치과위생사의 역할 및 업무범위의 발전과정' 요건에 따라 고찰하는 것이다. 미국치과위생사는 전문직 요건을 형성하고 있고 사회적 분위기 역시 전문직으로 인식하고 있다. 이에 미국치과위생사가 오늘날의 모습으로 전문직화해 온 과정과 그 특징을 규명하는 데 연구목적을 두고, 이 목적을 달성하기 위해 요건 별 문헌자료를 수집하고 분석하였다.

  • Purpose: The non-carious cervical lesion(NCCL) is a loss of tooth structure at the neck of affected teeth that is unrelated to tooth caries. The reported prevalence of NCCL varies from 5% to 85%. Prevalence and severity of lesions have been found to increase with age. They are becoming more significant as people live longer and become more aware of the importance of oral health. The purposes of this study were first, to examine the periodontal conditions associated with NCCL, and second, to investigate the clinical effects of class V restorations of NCCL on periodontal tissues. Materials and methods: The sample size was 982 teeth of 50 subjects(25 male, mean age $52{\pm}7$) who were seen at the Department of Periodontology, Pusan National University Hospital. At the baseline examination, clinical periodontal parameters were measured. After the initial examination, 24 patients who were absent from hypersensitivity were selected. The teeth with NCCL were randomly divided into the test and control groups. The teeth in the test group were restored with flowable resin; the control teeth were not restored. Six months later, the clinical examinations were repeated. The data were analyzed using the SPSS program. Results: The results were as follows: 1) NCCL occurred on 45.8% of examined teeth. The percentage of affected teeth was higher in maxillary and premolar teeth. 2) The shallow saucer type was the most common. 3) Teeth with NCCL had more gingival recession, lower attachment level, and higher incidences of bleeding on probing(BOP) and plaque than NCCL-free teeth. 4) Six months later, gingival recession, attachment level, the percentages of BOP and plaque in the test group were lower than in the control group(p<0.05). Conclusion: NCCLs were more found in maxillary teeth, especially in premolar teeth. The results suggest that the restoration of NCCL could affect some periodontal parameters favorably.

  • In order to facilitate the Korean government's efforts in integrating family planning and maternal & child health at the primary health care level (or township level), the Soon Chun Hyang College of Medicine, with the financial and technical assistance of WHO, has under-taken a service research project. The project has employed a quasi-experimental study design introducing interventions tat provide crucial factors lacking in the ongoing government programs such as midwives and qualified referral physicians. The study is being conducted in three locations, one control area and two study areas. Before introducing trained Nurse/Midewives into the study areas, a baseline prevalence survey was undertaken from 15 July 1981 to 10 August 1981 in selelcted townships of Seosan County. In this sample survey of bath the study and control areas, 2,484 eligible women (97% reponse rate) were interviewed to obtain benchmark data on basic evaluation indicators related to family planning and maternal and child health. The salients results were summarized as follows.: 1. CONTACT RATES WITH HEALTH WORKERS; During the year preceding the survey, 12% of women were visited by government health workers. The primary reason for such visits by health workers was family planning (45% of the visits). About 34% of the women visited the health centers during the year. The primary reason for visiting health centers was immunizations for their children (45% of the visits). 3. FAMILY PLANNING USE RATE; The baseline data showed little difference between women in the study area and the control area on contraceptive use. Approximately 59% were currently using some methods. However, among those current users, almost half were practicing less effective methods of birth control such as rhythm or withdrawal. Among other methods, the tubectomy was the most popular (16%), while use of the IUD, oral pill and condom together reached only 14%. 3. PRENATAL CARE RATE; About 75% of the women reported no prenatal care for their last births (the youngest child of each women), Additionally, among women received prenatal care, over half had only one visit. 4. ATTENDANCE AT DELIVERY; Most of the women surveyed (over 80%) were attended by a non-medical person during their last delivery. These figures are somewhat comparable to the national figure of 84% for remote areas. 5. POSTNATAL CARE; The proportion of women reporting postnatal care was only 4.5%, and postnatal care was not received by the majority of women surveyed. 6. CHILD HEALTH CARE: In contrast to the low rate of maternity care for women themselves, most women reported obtaining immunization care for their children. About 75% of the women obtained Polio and/or DPT, 58% BCG, and 44% Measles vaccine for their children. However, in terms of illness care, while 35% of the women stated that their youngest child had been sick during the month preceding the survey, only 28% of these women took their child to the clinic for treatment. 7. COMPLICATIONS OF PREGNANCY AND DELIVERY AND ABNORMALITIES IN THE NEWBORN; Among all last deliveries, 18% of the women had pregnancy complications and 9% of the women had complications during delivery About 5% of the women reported abnormality in their most recent newborn. 8. REPRODUCTION EFFICIENCY; PERINATAL MORTALITY AND INFANT MORTALITY Based on data from the pregnancy history in this survey, reproduction efficiency was estimated. Out of the 11,154 pregnancies reported by all women surveyed, foetal loss was 21% (almost 16% were induced abortions) and infant deaths before reaching one year old were 3.1%. The reproduction efficiency was, therefore, reduced to 76%. In terms of perinatal and infant mortality rates, the former was 40.2 per 1,000 total births and the latter was 39.3 per 1,000 live births. Both rates described J shaped relationships with age of mothers and parity, and they were also correlated with birth interval and mother's education. In summary, this baseline survey data indicated a need for (1) improving contraceptive practices with more effective methods to prevent unwanted pregnancies and (2) providing better services for maternal and child care to protect wanted pregancies. In the Korean rural setting. the author believes that the latter is more important as the value of each child has increased as a result of the family planning campaign for the past two decades. This calls for more effective integration of Family Planning and MCH programmes to meet the needs of the family in each stage of the child bearing and rearing period with deploying more qualified personnel than the current government program personnel.
