BACKGROUND The authors conducted a clinical study to examine the effectiveness of treatments other than replacement for defective Class I and Class II resin-based composite (RBC) and amalgam (AM) restorations. METHODS The authors recruited 66 patients (age range, 18-80 years) with 271 Classes I and II defective restorations (RBC = 78 and AM = 193). They(More)
BACKGROUND/AIM Alkali generation by oral bacteria plays a key role in plaque pH homeostasis and may be a major impediment to the development of dental caries. To determine if the capacity of oral samples to produce ammonia from arginine or urea was related to caries experience, the arginine deiminase system (ADS) and urease activity in saliva and dental(More)
This study was conducted to assess caries treatment thresholds among Japanese dentists and to identify characteristics associated with their decision to intervene surgically in proximal caries lesions within the enamel. Participants (n = 189) were shown radiographic images depicting interproximal caries and asked to indicate the lesion depth at which they(More)
BACKGROUND The authors tested the hypothesis that surface-finishing treatments and the type of storage solutions significantly affected the staining of resin-based composites, or RBCs, and unfilled resins, or URs. METHODS Fifty-four RBC and 54 UR disks were polymerized through a polyester film strip (Mylar, DuPont, Wilmington, Del.) and polished in one of(More)
OBJECTIVE In a seven-year prospective cohort study, the authors assessed the longevity of defective resin-based composite (RBC) restorations that were not treated or were treated by means of repair, sealing, refinishing or total replacement. They also aimed to identify and quantify the main reasons clinicians diagnosed restorations as defective. METHODS(More)
OBJECTIVES Practice-based research networks (PBRNs) provide a venue to foster evidence-based care. We tested the hypothesis that a higher level of participation in a dental PBRN is associated with greater stated change toward evidence-based practice. METHODS A total of 565 dental PBRN practitioner-investigators completed a baseline questionnaire entitled(More)
OBJECTIVES Few studies have examined dentists' subjective ratings of importance of caries risk factors or tested whether dentists use this information in treatment planning. This study tested several hypotheses related to caries risk assessment (CRA) and individualized caries prevention (ICP). METHODS Data were collected as part of a questionnaire(More)
BACKGROUND The authors evaluated the performance of a giomer restorative material (Beautifil, Shofu, Kyoto, Japan) with a self-etching primer (FL-Bond, Shofu) for posterior restorations. MATERIALS AND METHODS Two clinicians placed 26 Class I restorations and 35 Class II restorations in 31 patients ranging in age from 21 to 62 years (mean age, 34 years).(More)
BACKGROUND A number of articles have addressed differences in productivity between male and female dentists, but little is known about differences between the sexes in practice patterns regarding caries management. METHODS In this study, the authors surveyed general dentists who were members of The Dental Practice-Based Research Network (DPBRN) and who(More)
INTRODUCTION This article reports on the feasibility of conducting a large-scale endodontic prospective cohort study in The National Dental Practice-Based Research Network. This study was designed to measure pain and burden associated with initial orthograde root canal therapy (RCT) and to explore potential prognostic factors for pain outcomes. The main(More)
