PURPOSE. Prevention of xerostomia and stress is important to prolong healthy life expectancy and improve the quality of life. We aimed to investigate the effects of tongue rotation exercise for increasing salivary secretions and stabilizing salivary stress hormone levels. MATERIALS AND METHODS. Twenty four participants without subjective oral dryness were enrolled. The exercises comprised tongue rotation exercise and empty chewing. The salivary stress hormone level was measured using a Salivary Amylase Monitor. Unstimulated whole saliva volume and salivary amylase activity were measured before tongue rotation exercise or empty chewing and subsequently 5, 10, and 15 minutes after these exercises. Differences in the rates of change of unstimulated whole saliva volume and salivary amylase activity were analyzed by repeated measure analysis of variance. RESULTS. Statistically significant differences among the rates of change were not observed after empty chewing for unstimulated whole saliva volume and salivary amylase activity at the four measurement times. However, the rate of change of unstimulated whole saliva volume and salivary amylase activity were statistically significantly different among the four time points: before the tongue rotation exercise and 5, 10, and 15 minutes post-exercise (P<.05 and P<.01, respectively). CONCLUSION. Tongue rotation is effective in increasing saliva secretion, reducing stress, improving oral function, and extending healthy life expectancy.

Saliva have many important functions in the maintenance of oral health. Saliva contains protective components, antibacterial enzymes, and other rubricating glycoprotein elements. When the salivary flow decreases of the salivary composition changes, a normally healthy mouth can become susceptible to caries, periodontal disease, and mucositis, and other diseases. Salivary peroxidase system acts as an antimicrobial factor in the oral cavity, having a role in the prevention of dental plaque accumulation, dental caries and gingivitis. Recently, this enzyme system has been introduced by many researchers in the form of toothpaste, mouthwash or moisturizing gel for use in patients with various disease states . The author prescribed the peroxidase system containing gel (Oralbalance) to the 18 Burning Mouth Syndrome (BMS) patients for 1 week and investigated the changes of the subjective symptoms, $HOSCN/OSCN^-$ levels of unstimulated whole saliva, and the salivary flow rates. The obtained results were as follows : 1. The patients reported decrease in all symptoms of BMS after the use of peroxidase system containing gel, particulary, a significantly higher decreases of dry mouth and burning symptoms. 2. Decreased $HOSCN/OSCN^-$ levels of unstimulated whole saliva were detected in the patients with BMS after the use of perosidase system containing gel for 1 week. 3. There was no difference between the flow rates of unstimulated whole saliva before and after uses of peroxidase system containing gel for 1 week.

Objectives : This study was performed to evaluate the salivary secretion, salivary pH and cariogenic activity using unstimulated whole saliva in patients with hematologic malignancy. Methods : Nineteen patients (9 male, 10 female) who had hematologic malignancy and were treated with chemotherapy or bone marrow transplantation, and nineteen normal volunteers (7 male, 12 female) as control group were included. The mean age of patients group and control group was 45.1 and 46.7 years, respectively. Patients group was examined salivary secretion, salivary pH, and cariogenic activity using unstimulated whole saliva and was compared with control group. Results : In comparison with control group, salivary secretion, salivary pH and salivary buffer capacity were significantly lower in patients with hematologic malignancy (p<0.01). Both cariogenic activity(p<0.01) and the number of Lactobacilli(p<0.05) are higher in patients group than control group. Conclusions : These results suggest that the unstimulated whole salivary secretion, pH and buffer capacity were lower in patients with hematologic malignancy than control group. Cariogenic activity is higher in patients with hematologic malignancy than control group. Such salivary factor and cariogenic activity can increase the possibility of induction of dental caries.

The purpose of this study was to evaluate the effect of galvanic current between different metallic restorations on human saliva. The rate of salivary flow and concentrations of IgG, IgM, sIgA and lactoferrin were measured. In this study, unstimulated whole saliva collected before restoration was regarded as control group and unstimulated whole saliva collected 10 minutes, 1 day, 1 week, and 1 month after restoration were regarded as experimental groups. Following results were obtained from this study. 1. There were some differences in values of salivary flow rate between experimental groups, but the changes in values compared to those of the control group were not statistically significant(P>0.05). 2. Measurements of major antibacterial components of saliva showed that while the concentrations of IgG and IgM decreased significantly 1 week and 1 month after restoration(P<0.05), changes in values of sIgA and lactoferrin were not statistically significant(P>0.05). 3. In vitro measurements of galvanic currents decreased sharply in the first 20 seconds and thereafter decreased gradually. Galvanic current values measured in the early stages were greatly varied, but after 2 hours, the values in all groups approximated each other.

구강건조증 환자에서 자주 발생하는 구강 연조직과 경조직의 손상은 구강건조증 환자의 삶의 질에 심각한 문제를 일으킨다. 타액선의 기능을 완전히 상실한 구강건조증 환자의 경우 인공타액은 유일한 처치법임에도 불구하고, 현재 통용되고 있는 인공타액은 환자들의 기대치에 비해 많이 부족한 실정이다. 본 연구는 CMC 용액과 인공타액의 점도와 습윤성을 비교함으로써 향후 이상적인 인공타액의 개발에 필요한 정보를 얻고자 시행되었다. CMC를 타액모방완충용액(simulated salivary buffer, SSB)과 증류수에 용해시켜 동물 mucin 용액을 완성한 후, 이를 인체 전타액, 인체 개별 타액선 타액, 그리고 CMC를 주성분으로 하는 인공타액인 Salivart 및 Moi-Stir와 비교 분석하였다. 점도는 cone-and-plate digital viscometer로 검체 당 6개의 전단율에서 측정하였고, 습윤성은 아크릴릭 레진과 Co-Cr alloy 표면 위에서의 접촉각 측정을 통해 평가하여 다음과 같은 결론을 얻었다. 1. CMC 용액의 점도는 CMC 농도에 비례하여 증가하였으며, 0.5% CMC 용액의 점도는 비자극성 전타액의 점도와 유사하였다. 반면에 CMC 용액의 접촉각은 점도와는 반대로 CMC 농도를 증가시킴에 따라 감소하였다. 2. 인체 타액의 점도는 전단율 증가에 따라 감소하는 non-Newtonian fluid의 특성을 나타내었다. 다양한 전단율에서의 평균 점도는 자극성 이하선 타액, 자극성 전타액, 비자극성 전타액, 자극성 악하선-설하선 타액의 순으로 증가하였다. 3. 인체 타액의 접촉각은 점도와는 반대로 자극성 이하선 타액, 자극성 전타액, 비자극성 전타액, 자극성 악하선-설하선 타액의 순으로 감소하였다. 4. 타액모방완충용액에 용해시킨 CMC를 가열하여 변성시킨 경우 점도가 감소하였다 (P < 0.01, 전단율 $90s^{-1}$). 5. 인체 타액의 아크릴릭 레진 표면에서의 접촉각은 인체 타액의 Co-Cr alloy 표면에서의 접촉각보다 유의하게 작은 것으로 나타났다 (P < 0.01). 6. 인체 타액의 아크릴릭 레진 표면에서의 접촉각은 CMC 용액의 아크릴릭 레진 표면에서의 접촉각보다 유의하게 작은 것으로 나타났다 (P < 0.01). 이번 연구에서 CMC 용액의 유동학적 성질을 객관적으로 확인할 수 있었으며, 이상의 결과를 종합하여 보면 CMC는 향후 효과적인 인공타액의 개발에 있어서도 중요한 역할을 수행 할 것으로 기대된다.

Purpose : The purpose of this study is to observe the salivary immunoglobulin level in whole saliva of infected patients and also to investigate the changes of immunoglobulin level according to its management. Materials & Methods : Thirty infected patients who have been admitted to the dept. of oral and maxillofacial surgery of Pusan National University Hospital have been selected as subjects and we analysed the changes of immunoglobulin level of $1.5{\sim}3.0ml$ of unstimulated whole saliva collected throughout four times; the day before treatment, the first day after treatment, the third day after treatment and the day before discharge. We also compared them with immunoglobulins in whole saliva that was collected from 4 normal persons as control group. In radial immunodiffusion technique with BACKMAN(Array 360 system, McLean, USA), level of immunoglobulins was analyzed. Results : The isotypes of Ig that have been found in saliva of normal persons were IgG, IgA, IgM and IgE and their mean level was 8.23, 36.41, 4.38, and 2.38 respectively. In the infected patients before the treatment, the level of IgG, IgA was remarkably higher than that of normal persons, however we could not find the difference on the level of IgM, IgE. As the infection was healing, the level of IgG, IgA was decresing significantly.
