The study also compared the retention of this sealant in vivo with its nonfluoride-containing analog, Prisma-Shield. One hundred forty-seven pairs of caries-free permanent first molars in 82 children, aged six to nine years, were sealed with the two sealant types. Samples of whole unstimulated saliva, as well as site-specific saliva samples, were collected from 20 randomly selected subjects and analyzed for fluoride content. Complete or partial coverage was observed for 274 of 275 teeth evaluated at six months and for all 199 teeth evaluated at 12 months. There were no statistically significant differences in retention between the two sealants at 6 to 12 months. The release of fluoride was intense, but of short duration. Mean whole saliva fluoride content was 2.9 ppm +/- 0.13 (S.E.), and site-specific saliva fluoride content was 11.4 ppm +/- 1.02 (S.E.) buccal to the fluoride-releasing sealant at 30 minutes; both values returned to baseline within 24 hours. It was concluded that the addition and subsequent release of fluoride in Fluroshield did not decrease its retentiveness.","PeriodicalId":75715,"journal":{"name":"Clinical preventive dentistry","volume":"12 4","pages":"24-7"},"PeriodicalIF":0.0,"publicationDate":"1990-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13244425","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}

Those patients at risk for xerostomia (i.e. patients taking antidepressant and antihypertension medication, or having irradiation and pathology of the parotid) should be tested with the Lashley cup to determine if acceptable flow rates are being maintained or compromised. Adequate flow rates for dentulous and edentulous patients are significantly different. Group A had a mean flow rate of 0.75 ml/min while Group B (edentulous) had a mean flow rate of 0.5 ml/min. Using an independent t-test, there was a significant difference at the p less than 0.05 level. Both hard and soft tissue are ravished by xerostomia. In dentulous patients, caries rates soar and make the prognosis for fixed prosthetics poor. In edentulous patients there is an ineffective film thickness resulting in high abrasion (sore spots) and decreased retention of removable prosthesis. Masticatory and gustatory stimulants may help alleviate these symptoms. However, the measurement of salivary flow is an invaluable diagnostic tool in determining the prognosis of alternative treatment plans. Because the elderly are more likely to be taking medications which result in xerostomia, this diagnostic tool should be used on a routine basis with geriatric patients.","PeriodicalId":75715,"journal":{"name":"Clinical preventive dentistry","volume":"12 4","pages":"10-2"},"PeriodicalIF":0.0,"publicationDate":"1990-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13243731","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}

Baseline buccal and lingual plaque indexes were found comparable between the groups and the mean buccal plaque scores were considered low by normal standards. During the use of the three experimental silica-based pastes, one containing strontium acetate, one strontium acetate and MFP and a commercially available formaldehyde-containing paste, plaque scores fell significantly and to a similar extent in all four groups. After cessation of treatment at 6 weeks, plaque scores had increased back to baseline in all groups. During the use of a diatomaceous earth/strontium chloride toothpaste, commercially available, plaque scores increased significantly, both from baseline and by comparison with the other four pastes. Nevertheless, plaque scores in this group returned to baseline levels after cessation of treatment and a return to use of a conventional non-desensitizing toothpaste. The effects of all but the diatomaceous earth/strontium chloride toothpaste would not be inconsistent with previous experience in toothbrushing studies where patients are monitored regularly. The effects on plaque did not necessarily coincide with the previously reported treatment benefit of the respective products in dentin hypersensitivity.","PeriodicalId":75715,"journal":{"name":"Clinical preventive dentistry","volume":"12 4","pages":"28-33"},"PeriodicalIF":0.0,"publicationDate":"1990-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13244426","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":"Penetration of etched enamel and dentin cavity surfaces by bonding agent/composite resin.","authors":"J M Brady, J A Clarke-Martin","doi":"","DOIUrl":"","url":null,"abstract":"Mechanical and adhesive advantage of resin bonding agents depend upon the ability to penetrate microspaces created with acid-etchants and close adaptation to cavity surfaces. As a replicating material, these resins may reveal morphologic characteristics of the cavity surfaces not seen by direct scanning electron microscope (SEM) investigation. The purpose of this study was to describe, with the SEM, the resin replications of acid-etched cavity walls of Class V cavity preparations in the labial and lingual surfaces of extracted premolar teeth. Cavities were prepared in the gingival third of these surfaces in 26 freshly extracted human premolar teeth using fissure burs in water-cooled, high-speed handpieces. The cavosurface margins were bevelled. The preparations were washed in tap water, dried, etched for 20 seconds with 35% phosphoric acid, coated with light-cured bonding agent and filled with light-cured composite resin in two applications. The teeth were dissolved in acid and the cavity walls of the composite examined in the SEM. Features observed included: (a) Type II resin penetration of interrod regions, (b) resin penetration of the lamellae to the dentino-enamel junction (DEJ), (c) a 10-20 microns step in surface contour at the DEJ, with penetration of terminal tubule branches, (d) insular regions of deep dentin tubule penetration and (e) 100-300 microns deep, 10-30 microns incremental microlamellar penetrations into the enamel at the DEJ corresponding to enamel tufts.","PeriodicalId":75715,"journal":{"name":"Clinical preventive dentistry","volume":"12 3","pages":"30-3"},"PeriodicalIF":0.0,"publicationDate":"1990-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13239125","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":"Mechanical devices versus antimicrobial rinses in plaque and gingivitis reduction.","authors":"P Finkelstein, K G Yost, E Grossman","doi":"","DOIUrl":"","url":null,"abstract":"The effectiveness of mechanical oral cleaning and oral antimicrobial rinses was compared for gingivitis and bacterial plaque control in 158 subjects. Teeth were brushed ad lib throughout; four of the five groups used either an interdental cleaner, dental floss, an essential oil mouthwash or a cetypyridinium mouthwash. Gingival bleeding (EIBI), visual inflammation (VGI), and tooth plaque coverage were evaluated at zero, six and 12 weeks of product use. After six weeks, bleeding reduction was 42% greater for the interdental cleaner and 21% greater for the dental floss than for the control. All groups showed a further decrease after 12 weeks, but only the 49% reduction of the interdental cleaner was significantly greater than the control. The rinses showed no more reduction in bleeding sites than the control throughout the study. VGI scores were no different from the control for any of the groups. However, the EIBI proved much more sensitive than the visual method finding three times as many inflamed sites. Plaque was reduced by both antimicrobial rinses 27% more than the control over 12 weeks; the interdental cleaner and dental floss groups showed no significant incremental plaque reductions. The results suggest antimicrobial rinses reduce plaque on visible tooth surfaces, but do not penetrate sufficiently between teeth to affect interdental plaque and thus interdental inflammation. However, by disturbing interdental plaque, both dental floss and the interdental cleaner have little effect on visible tooth surface plaque accumulation, yet produce a significant reduction in gingival inflammation.","PeriodicalId":75715,"journal":{"name":"Clinical preventive dentistry","volume":"12 3","pages":"8-11"},"PeriodicalIF":0.0,"publicationDate":"1990-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13239129","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}
