Incisors were obtained and painted with an acid-protective varnish, excluding 2 mm x 6 mm windows on the labial surface. Each tooth had an unfilled resin placed over half the area of the window; the remaining area was not treated. One hundred microns longitudinal sections were obtained from the treated and non-treated sites. Polarized photomicrographs were taken of each section, in imbibition media of air, water and Thoulet's (R.I.: 1.41, 1.47), representing a minimum of 1%, 5%, 10%, and 25% pore volume respectively. The sections were then painted with an acid-protective varnish so that only the external surface was exposed and placed in separate closed environments of a non-fluoridated artificial saliva. One section from each tooth had unfilled resin on the external surface, one section had only natural enamel exposed, and a third section had the external surface varnished to act as a control. The teeth were thermocycled at 10 degrees C and 50 degrees C, 20 cycles per day for three months; they were also cycled through artificial caries challenge (pH 4.4) for 35 minutes, three times per day. Sections were then photographed under polarized light, as before, and areas of lesions were digitized. Results demonstrated caries to be present on all non-treated enamel surfaces exposed to the artificial caries challenge. Significantly less enamel demineralization occurred when an unfilled resin was placed on it (p < 0.001).","PeriodicalId":75715,"journal":{"name":"Clinical preventive dentistry","volume":"14 6","pages":"22-4"},"PeriodicalIF":0.0,"publicationDate":"1992-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12472846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Enhancing flossing compliance in college freshmen.","authors":"J G Bagley, K G Low","doi":"","DOIUrl":"","url":null,"abstract":"This study examined the relationship between dental compliance and health locus of control in 41 college freshmen. Subjects were randomly assigned to either a control (N = 13) or experimental (N = 28) group. Dental flossing compliance was assessed in all subjects using a brief dental exam that assessed pocket depth and plaque as indexes of flossing behavior. The Multidimensional Health Locus of Control Scale was used to measure health locus of control. An educational, low-fear intervention, consisting of the presentation of a pictorial diagram of the progression of periodontal disease and discussion of the importance of flossing was presented to the experimental subjects before monitoring began. Control subjects underwent a brief dental examination and flossing instruction only. Self-reported flossing compliance was monitored for 24 days following the dental examination and intervention. Significant decreases in the dental exam variables associated with plaque were found for both the experimental and control conditions. The low-fear, educational intervention had no significant impact on compliance. Instead, a dental exam and self-monitoring were as effective at increasing flossing compliance as the more time-consuming educational approach. A significant increase in internality of health locus of control across all subjects was also found. No significant interaction was found between health locus of control and group, but a trend was apparent. Control subjects who were externally oriented had the lowest flossing compliance scores while internal subjects in both conditions had higher flossing compliance scores.","PeriodicalId":75715,"journal":{"name":"Clinical preventive dentistry","volume":"14 6","pages":"25-30"},"PeriodicalIF":0.0,"publicationDate":"1992-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12472849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plaque and gingivitis were scored after 3 and 6-month use of the assigned dentifrice. At the end of the study, the triclosan group showed an average reduction, relative to the control group, of 12% in plaque accumulation and 20% in gingivitis. Both were statistically significant at p < or = 0.0001. The effect of the triclosan dentifrice was most pronounced on the more severe manifestations of plaque and gingivitis. The improvement in the gingival parameters at 6-months relative to the control dentifrice was statistically significant at p < or = 0.0001.

Twenty-eight consenting individuals were randomly assigned to each of three phases (six weeks in duration) consisting of chewing xylitol gum, chewing sorbitol gum and a non-chewing phase. Subjects chewed one stick after every meal and at two other times for a total of five sticks per day. At the completion of each treatment phase, plaque and gingival indexes were performed and plaque was later collected. Calcium concentration in plaque was determined by atomic absorption spectophotometry. Reductions in plaque indexes were significant for both xylitol gum (p < 0.001) and sorbitol gum (p < 0.05) when compared to the no chewing period. The gingival indexes reflected a decrement in gingival inflammation with both xylitol and sorbitol, though only sorbitol values were statistically significant (p < 0.05). Chewing xylitol and sorbitol gums reduced plaque accumulation and gingival inflammation. In addition, both gums enhanced the remineralization potential of plaque. Xylitol gum showed a superior effect with respect to remineralization potential and plaque reduction. Sorbitol gum had a superior effect on gingival health but not significantly so.","PeriodicalId":75715,"journal":{"name":"Clinical preventive dentistry","volume":"14 5","pages":"31-4"},"PeriodicalIF":0.0,"publicationDate":"1992-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12466310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All patients had been under dental supervision by the same dentist for more than one year, and were familiar with the procedure during checkups. This study showed a significant rise in systolic blood pressure (8.6 mmHg) and a tendency towards increased diastolic pressure (2.9 mmHg) during dental checkups in comparison with the values recorded 24 hours earlier during normal daily activity. These results were independent of the blood pressure classification (normotensive, borderline or hypertensive) of the patients and are comparable to the increases measured during a visit to the GP. Neither the sex nor the manner of the dentist had any significant influence on either the systolic or diastolic pressure values during the checkup. Nor did the phobic level of the patients significantly influence blood pressure values during the dental checkup. On the basis of the results of this study, it may be concluded that regardless of whether the patient is phobic or non-phobic, and regardless of the sex and manner of the dentist, blood pressure measurements taken during dental checkups are reliable and can be used for referral decisions.","PeriodicalId":75715,"journal":{"name":"Clinical preventive dentistry","volume":"14 5","pages":"5-10"},"PeriodicalIF":0.0,"publicationDate":"1992-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12466312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
