  • Objectives : The aim of this study was to confirm the characteristics of oral malodor patients by evaluating the differences of salivary flow rate, secretory immunoglobulin A (sIgA) level in saliva between the patient and control groups, and the correlation with the tongue coating, volatile sulfur compound (VSC), salivary flow rate and sIgA level in saliva in the patients group. Methods : Forty-seven patients with oral malodor and twenty healthy volunteers were included in this study. Their tongue coating was assessed with the Winkel tongue coating index, and salivary flow rate, sIgA concentrations in saliva and the level of VSC in oral cavity were measured. Results : There were no significant differences of the salivary flow rate and the sIgA level in saliva between the patient and control groups, but there was a significant relationship between the accumulation of tongue coating and the level of VSC in oral cavity. Conclusions : Our results suggest that tongue coating is closely related to oral malodor, but further studies are needed to confirm the relationship between tongue coating and sIgA level in saliva.

  • This study was undertaken to observe the relationship between salivary IgA, IgG, agglutinin titer & dental caries. The subjects divided into two groups, an active caries group (AC group) and caries-free and treated caries group (CFTC group). The AC group consisted of 36 subjects who had one or more carious lesions and the CFTC group of 12 subjects who had no evidence of caries or had filled teeth without present carious teeth for the last six months. The IgA, IgG and IgM levels in their saliva were measured by single radial immunodiffusion method using a disposable low-level immunodiffusion plate. The salivary agglutinin titers to Streptococcus mutans were measured by microtitration system. The results were as follow; 1. The mean value of IgA concentration in saliva of AC group was slightly higher than that of CFTC group, but its difference was slight. 2. The mean value of IgG concentration in saliva of AC group was slightly lower than that of CFTC group. The IgM concentration in saliva of both groups was neither below 1.1 mg/dl nor detected on LC partigen immunodiffusion plate. 3. There was no difference in the agglutinin titer to S. mutans antigen by serotypes, but low level agglutinin to type d was measured in both groups. 4. AC group showed low correlation between IgA, IgG & DMFT, but CFTC group revealed negative correlation. 5. The relationship between salivary IgA & agglutinin titers to S. mutans was low correlation in AC group, but CFTC group showed significant positive correlation. (P<0.05) 6. There were no specific correlations among the concentrations of salivary immunoglobulins, agglutinin titers to S. mutans, and the DMF teeth. They had no close concern to induce the dental caries.

  • Background: The aim of this work was to investigate if serum and salivary auto-antibodies, isotypes IgG and IgM, against HER2 and MUC1 tandem repeat fragments could play a role in breast cancer screening. Materials and Methods: Our case-control study was conducted in breast cancer patients, in early stages (n=29), at the gynecology service, Maternity Souissi Hospital, Rabat, Morocco and healthy woman (n=31). Salivary and serum auto-antibodies against HER2 and MUC1 (tandem repeat) were assessed by enzyme-linked immunosorbent assay (ELISA) and compared between patients and healthy women using the Mann-Whitney U test. A P-value <0.05 was considered to be statistically significant. Results: Our data showed higher expression of all serum and salivary autoantibodies in patients as compared to healthy women p<0.05. However, serum IgM anti-MUC1 expression did not show a significant difference between cases and controls (p=0.79). Similarly, salivary IgG anti-HER2 expression did not differ (p=0.15). The correlation between the different isotypes of antibodies revealed that the highest correlation was between salivary IgG anti-HER2 and salivary IgG anti-MUC1(r=0.65). In fact, we have found in saliva the correlation between autoantibodies anti-MUC1 and anti-HER2 more important than in serum (r=0.59 and r=0. 55). However, the correlation between serum and saliva values for all antibodies was weak. Conclusions: Autoantibodies against HER2 and MUC1 may provide a useful approach in breast cancer screening when using both serum and saliva values.

  • AgI/II of Streptococcus mutans(S. mutans) is an important virulence factor that contributes to the pathogenesis of S. mutans-induced dental caries. In oral cavity, salivary IgA antibodies act as safeguards against enormous challenges from oral bacteria. IgA antibodies inhibit adherence of cariogenic microorganisms to hard surfaces. Analysis of salivary IgA against AgI/II can be very useful diagnostic and powerful communication tools to the dental caries The purpose of this study was to investigate correlation between salivary AgI/II specific IgA and incidence of dental caries among children and young adults. Subjects consisted of 28 children and 18 adults. They were assigned to four groups : Group I deft index $\leq$3), Group II(deft index $\geq$4), Group III(DMFT index $\leq$3), Group IV(DMFT index $\geq$4) and they was divided two groups into caries resistant group and caries susceptible group. The study group were examined caries activity and their salivary IgA was evaluated by enzyme-linked immunosorbent assay. The results are as follows : 1. There was a positive correlation between the number of S. mutans and caries activity. 2. The titer of salivary IgA against the AgI/II was significantly higher in caries resistant group than caries susceptible group(p<0.01). 3. The titer of salivary IgA against the AgI/II in Group III was significantly higher than Group II(p<0.05).

  • The use of relaxing cosmetic products is more and more widespread on the self care market, since stress is considered as a major cause of discomfort in modem life. Cortisol, the stress hormone, helps the human body to regulate itself by acting on carbonhydrate, proteins and fat metabolisms. IgA are immune molecules involved in the stress response of the human body. The less the human body is stressed, the more the salivary IgA rate increases. Salivary cortisol and IgA have the advantage of being easily assessed with non invasive methods. Finally, conductance is the measurement of the modification in the electrical resistance of the skin. By this means, the measurement of the conductance enable the assessment of somebody's stress.(omitted)

  • The aim of this study is to develop and establish rapid, convenient, and accurate method of analyzing salivary IgA against S. mutans semi-quantitatively. Relative salivary IgA titer was calculated as maximum dilution fold of S. mutans protein that was not detected by salivary antibody after measuring relative intensity of the immune blot bands by densitometry. Analyses were performed in caries-experienced and non-experienced children. Mean IgA titer of non-experienced group shows higher level than that of caries-experienced without statistical significance due to high individual variety of antibody titer in non-experienced group: $2^{6.278{\pm}2.260}$ in non-experienced group and $2^{5.730{\pm}0.499}$ in caries-experienced group(p=0.464). Those results suggest that naturally induced salivary IgA antibodies against S. mutans were present in all subjects, but high titer of antibodies were not achieved in caries-experienced group. On the contrary, antibody titer in non-experienced group shows marked individual variations suggesting that antibody production is multifactorial. In conclusion, immune-slot blot method developed in this study would be useful and applicable in semi-quantitative analysis of antibodies.

  • This study investigated the relationship between dental caries and various oral factors in subjects with Down's syndrome. We compared 25 subjects with Down's syndrome with 63 healthy control. The dental caries index and plaque index were examined, and the total salivary immunoglobulin A and S. mutans specific salivary immunoglobulin A concentration were measured using ELISA. The S. mutans counts, Lactobacillus counts and buffer capacity were measured with Dentocult test medium. The decayed and filled surface index of deciduous teeth in subjects with Down's syndrome was lower than in controls(p<0.001). The plaque index and total salivary immunoglobulin A concentration showed no difference, S. mutans specific salivary immunoglobulin A concentration and buffer capacity in subjects with Down's syndrome were lower than in controls(p<0.001). There was no significant difference between two groups in the S. mutans counts and Lactobacillus counts. In 9-11 year age group, S. mutans counts in subjects with Down's syndrome was lower than in controls(p<0.001) and S. mutans specific salivary immunoglobulin A concentration was lower(p<0.05). There was a high correlation among deciduous dental caries index and buffering capacity and S. mutans counts.

  • The present investigation was carried out to identify salivary components of mucosal pellicle and to explore the difference of mucosal pellicle components according to the location of oral mucosa. By using antisera and immunoblotting, high-(MG1) and low-(MG2) molecular-mass salivary mucins, amylase, IgA, proline-rich proteins(PRPs) were detected in mucosal pellicle in vivo. In addition, the data indicated that mucins, IgA and proline-rich proteins could be cleaved into lower-molecular-mass products, whereas the IgA, proline-rich proteins could also be cross-linked into higher-molecular-mass complexes. Mucosal pellicles from buccal, labial and palatal mucosa showed similar pattern in immunoblotting experiments using anti-MG2 and anti-PRPs antisera. The data from this study suggest that during mucosal pellicle formation multiple components of saliva adsorb to oral mucosal epithelial cell surfaces, and selected components can be proteolytically cleaved into smaller fragments and/or cross-linked into higher-molecular products.

  • As fermented milk has been regarded as health food, the consumption of fermented milk has been increasing significantly these days. But there is not sufficient information on the effect of fermented milk on oral health. We have investigated the effect of long-term intake of t\fermented milk on saliva in preschool children, Sixty-four healthy, unmedicated preschool children were included in this study and were divided into control, fermented milk, and milk groups. The experimental period was 210days. We investigated the number of slaivary S. mutans, lactobacilli, and Candida, salivary pH, viscosity, and the concentration of salivary IgA at the beginning of the experiment. We examined these parameters at 10, 60, 110, 160, and 210 days after. The obtained results were as follows : 1. There were increases in the numbers of slaivary S. mutans in all groups through the experimental period. But, there was no consistent and significant difference among groups. 2. There was no significant change in the number of salivary lactobacilli in the fermented milk group throughout the experimental period. 3. The numbers of salivary Candida in the fermented milk and milk groups showed less fluctuation than that of the control group through the experimental period. 4. There was no decrease of salivary pH in all groups through the experimental period. 5. There were increases in the values of salivary viscosity in all groups. But, there was no consistent and significant difference among groups. 6. There were no consistent and significant difference in the concentration of salivary IgA in all groups through the experimental period. 7. There were increases of dmfs rate in all groups. But, there were no significant difference within each groups.

  • Purpose: The purpose of this study was to investigate the effects of an essential oil mouthrinse with gingival massage on oral health in community indwelling elderly. Method: The subjects were composed of 61 healthy elderly at a Senior Welfare Center in J city. Thirty subjects in the experimental group were given toothbrushing education ongingival massage toothbrushing with an essential oil mouthrinse for 2 weeks(4 times per day, 3 minutes per session). The 31 subjects in the control group were given toothbrushing education ongingival massage toothbrushing. The effects of the treatment were measured by salivary pH, salivary IgA level, halitosis, oral subjective symptoms, and oral self care behavior scores before, right after and 2 weeks after the experiment. Results: Salivary pH was significantly increased(p=0.018) in the experimental group. Salivary IgA levels were not significantly different between the experimental and control groups; however, IgA levels of the experimental group were significantly increased(p=0.006) after time had passed. Halitosis was significantly decreased(p=0.002) in the experimental group. Oral subjective symptom scores were significantly decreased(p=0.000) and oral self care behavior scores were significantly increased(p=0.000) in the experimental group. Conclusion: Regular gingival massage toothbrushing with an essential oil mouthrinse could be an effective oral health nursing intervention for the elderly.
