This study investigated the relationship of arginine deiminase (ADS) and urease activities with dental caries through a case-control study. ADS and urease activities were measured in dental smooth-surface supragingival plaque and whole saliva samples from 93 subjects, who were in three different groups: caries-free (n = 31), caries-active (n = 30), and(More)
BACKGROUND Dental caries are largely preventable, and epidemiological evidence for a relationship between diet and oral health is abundant. To date, however, dentists' perceptions about the role of diet and dentists' practice patterns regarding diet counseling have not been clarified. OBJECTIVE THE PURPOSES OF THIS STUDY WERE TO: (1) examine discordance(More)
OBJECTIVES This study investigated the relationship between urease and arginine deiminase system (ADS) activities and dental caries through a cross-sectional study. MATERIAL AND METHODS Urease and ADS activities were measured in saliva and plaque samples from 10 caries-free subjects and 13 caries-active. Urease activity was obtained from the ammonia(More)
Replacement of dental restorations has been the traditional treatment for defective restorations. This five-year prospective clinical trial evaluated amalgam restorations with localized defects that were treated by means of repair or refurbishing. Fifty-two patients (50% female and 50% male, mean age 28.3 ± 18.1 years, range 18-80) with 160 class I and(More)
OBJECTIVE The purposes of this study were to (1) quantify dentists' practice patterns regarding caries prevention and (2) test the hypothesis that certain dentists' characteristics are associated with these practice patterns. DESIGN The study used a cross-sectional study design consisting of a questionnaire survey. PARTICIPANTS The study queried(More)
Items in clusters, such as patients of the same clinician or teeth within the same patient, tend to be more similar than items from different groups. This within-group similarity, represented by the intraclass correlation coefficient (ICC), reduces precision, yielding less statistical power and wider confidence intervals, compared with non-clustered samples(More)
OBJECTIVES To assess the relationships among alkali production, diet, oral health behaviors, and oral hygiene. METHODS Data from 52 subjects including demographics, diet, and oral hygiene scores were analyzed against the level of arginine and urea enzymes in plaque and saliva samples. An oral habit survey was completed that included: use of tobacco (TB),(More)
BACKGROUND Objectives were to: (1) determine whether and how often general dentists (GDs) provide specific dental procedures; and (2) test the hypothesis that provision is associated with key dentist, practice, and patient characteristics. METHODS GDs (n = 2,367) in the United States National Dental Practice-Based Research Network completed an Enrollment(More)
BACKGROUND Dentin hypersensitivity (DH) is a common problem encountered in clinical practice. The purpose of this study was to identify the management approaches for DH among United States dentists. METHODS One hundred eighty five National Dental Practice-Based Research Network clinicians completed a questionnaire regarding their preferred methods to(More)
BACKGROUND The objectives were to: (1) quantify patient satisfaction with treatment for early dental caries overall, and according to whether or not (2a) the patient received invasive treatment; (2b) was high-risk for dental caries, and had dental insurance; and (3) encourage practitioners to begin using non-invasive approaches to early caries management.(More)
