  • Purpose: Xerostomia is subjective feeling of dry mouth. It is complicated and multifactorial, which burdens clinicians in diagnosis and treatment of the problem. The goal of this study was to discuss the clinical importance of salivary flow rate, pH and subjective symptoms for evaluating oral dryness among young healthy male subjects. Methods: Thirty male participants were recruited in this study (mean age±standard deviation of 25.70±1.84). All participants completed 'Xerostomia Inventory' to measure subjective oral dryness scores. Unstimulated saliva and stimulated saliva were collected from each participant twice a day at 12:00 pm and 5:00 pm, using spitting method. Salivary flow rates and pH were measured immediately after collection. Relationship between objective and subjective measurements were analyzed. Results: There were excellent intra-examiner reliability for salivary flow rate and pH and good internal consistency for Xerostomia Inventory. Objective measurements and subjective symptoms did not exhibit positive association. Salivary flow rate in unstimulated and stimulated condition showed positive association and also for salivary pH. Stimulated salivary flow rate also presented positive correlation with stimulated salivary pH. Conclusions: Comprehensive assessment of objective measurements and subjective symptoms may be complimentary for assessing oral dryness, which would assist in implementing early interventions to improve patient's quality of life.

  • 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.

  • The purpose of this study is to evaluate salivary flow rate, salivary pH, and cariogenic activity using unstimulated saliva of the head and neck cancer patients. Twenty three cancer patients (19 males, 4 females) who had undergone chemotherapy and radiation therapy and twenty four healthy volunteers (14 males, 10 females) as a control were included. Salivary flow rate, salivary pH, and cariogenic activity using unstimulated saliva were examined. Compared to saliva of the control group, salivary flow rate (p<0.001) and salivary pH (p<0.001) were significantly lower in head and neck cancer patients. The colony counts of Lactobacilli was higher in head and neck cancer patients (p<0.05) than in control group. These salivary factors and cariogenic activity can increase the prevalence of dental caries in head and neck cancer patients.

  • During the past decade, many salivary parameters have been used to characterize disease states. Ghrelin (GAH) is recently-discovered peptide hormone secreted mainly from the stomach but also produced in a number of other tissues including salivary glands. The aim of this work was to examine the relationship between active (aGAH) and inactive (dGAH) ghrelin in the saliva and other salivary parameters in type II diabetic patients and healthy controls. Salivary parameters were assessed in a single measurement of unstimulated whole saliva from 20 obese and 20 non-obese type II diabetes patients, and in 22 healthy controls. Total protein and alpha-amylase were determined by colorimetric methods, and glucose by the glucose-oxidase method. Saliva aGAH and dGAH levels were measured using a commercial radioimmunoassay (RIA) kit. Salivary concentrations of aGAH and dGAH ghrelin were more markedly decreased in obese diabetic subjects than in the two other groups. Glucose and alpha-amylase levels were higher in diabetic subjects than in controls. Furthermore, there were correlations between GAH levels and BMI, and between GAH and blood pressure. However, there was no marked variability in saliva flow rates among the groups. These results indicate that measurement of salivary GAH and its relationship to other salivary parameters might help to provide insight into the role of ghrelin in diabetes.

  • 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.

  • 교정치료 중 구강 내 환경 변화를 파악하기 위하여 교정치료 시작 후 24개월까지의 임상적 구강위생지수 및 타액, 구강 내 미생물의 변화양상을 평가하였다. 30명의 환자를 대상으로 하여, 임상적 구강위생지수(DMFS [decayed, missing and filled surfaces], O'Leary's plaque index, plaque pH), 타액의 변화(비자극/자극시의 타액량, 완충능(buffer capacity), pH, 잠혈(occult blood)류량, 구강 내 미생물(Streptococcus mutans, Lactobacillus) 변화를 파악하였다. 추가적으로 설문지를 이용하여 구강위생관리 및 식습관을 평가하였다. 분산분석, 회귀분석 및 Spearman의 상관분석을 통해 데이터를 분석하였다. 교정치료 도중 DMFS 값은 유의성있게 증가한 반면, plaque index는 감소하였고, plaque pH는 산성을 나타내었다 (p = 0.23). 비자극 시 타액량은 치료 중 유의성있게 변화하였으며 (p = 0.13), 자극 시의 타액량은 여성에서 장치 부착 이후 증가하는 양상을 보였다. Buffer capacity는 남성에서 치료 도중 감소되었으며, 타액의 pH는 유지되었다. 구강 내 미생물 및 잠혈류량은 고위험 수준까지 증가하였으며 성별의 차이는 나타나지 않았다 (p > 0.05). 치료 전 plaque와 구강위생용품의 사용 (r = 0.429; p = 0.018), 최종 DMFS와 비자극 시의 타액량 (r = -0.372; p = 0.043) 간에 뚜렷한 상관관계가 확인되었다. 교정장치의 부착으로 인해 구강 내 미생물은 증가하고, plaque pH는 산성화되어 치주조직의 손상이 일어나게 되었다. 또한 Buffer capacity는 변하지만, 치료 기간중의 타액의 pH는 유지되었다.

  • 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.

  • The purposes of this study were to investigate the effect of pilocarpine-containing chewing gum for the treatment of xerostomia and to compare the effect of pilocarpine-containing chewing gum with that of pilocarpine oral administration. The 20 subjective and objective xerostomic patients were included in this study and divided into 3 groups. Five subjects were included in gum base chewing group, 10 in pilocarpine-containing gum chewing, and 5 in pilocarpine oral administration. The author measured unstimulated whole salivary flow rate, stimulated parotid salivary flow rate, pH of resting whole saliva, viscosity of stimulated whole saliva, and subjective symptoms and discomforts using VAS(visual analogue scale) at the beginning of the experiment. And the author investigated the changes of these factors at 1, 2, 3, and 4 week after. The obtained results were as follows : 1. There were significant increases in the unstimulated whole salivary flow rate in pilocarpine-containing gum chewing and pilocarpine oral administration groups. But there was no significant difference between pilocarpine-containing gum chewing and pilocarpine oral administration groups. 2. There was a significant increase in the stimulated parotid salivary flow rate in pilocarpine- containing gum chewing group. But there was no significant difference between pilocarpine- containing gum chewing and pilocarpine oral administration groups. 3. The change of salivary pH showed the increasing pattern in all groups. But there was no significant difference among groups. 4. There were no significant changes in the values of salivary viscosity in all groups through the experimental period. 5. There were significant decreases of VAS(visual analogue scale) in the degree of subjective symptoms and discomforts in pilocarpine-containing gum chewing and pilocarpine oral administration groups. But there was no significant difference between pilocarpine- containing gum chewing and pilocarpine oral administration groups.
