Laboratory Technician Assessment of the Quality of Single-Unit Crown Preparations and Impressions as Predictors of the Clinical Acceptability of Crowns as Determined by the Treating Dentist: Findings from the National Dental Practice-Based Research Network.

Purpose: In-laboratory assessment by laboratory technicians may offer insight to increase clinical success of dental crowns, and research in this area is lacking.

Concordance between practitioner questionnaire responses and observed clinical treatment recommendations for treatment of dentin hypersensitivity: findings from the National Dental Practice-Based Research Network.

Background: Few published reports have presented concordance between treatment choices selected by dentists in hypothetical clinical scenarios and treatment choices made by the same dentists in actual clinical practice. The aim of the current cross-sectional study, conducted within the Management of Dental Hypersensitivity (MDH) study, was to assess the potential value of practitioners' questionnaire responses regarding their typical treatment provided for management of dentin hypersensitivity (DH), by evaluating agreement between these responses and subsequently-observed recommendations recorded during actual clinical examinations.

Methods: A total of 171 practitioners enrolled in the National Dental Practice-Based Research Network completed both a questionnaire and a clinical study regarding methods they use to treat dental hypersensitivity.

Methods: Eighty-two dentists participated.

Patient-Centered Dentinal Hypersensitivity Treatment Outcomes: Results from the National Dental PBRN.

Dentinal hypersensitivity (DH) can have a significant impact on oral health and functioning, and it is a clinical symptom commonly managed by dentists during routine clinical practice. DH symptoms are typically elicited by otherwise innocuous, nonpainful stimuli applied to exposed dentin (e.g.

Surface characteristics and lesion depth and activity of suspicious occlusal carious lesions: Findings from The National Dental Practice-Based Research Network.

Background: A lesion on an occlusal tooth surface with no cavitation and no radiographic radiolucency but in which caries is suspected owing to surface roughness, opacities, or staining can be defined as a suspicious occlusal carious lesion (SOCL). The authors' objective was to quantify the characteristics of SOCLs and their relationship to lesion depth and activity after these lesions were opened surgically.

Methods: Ninety-three dentists participated in the study.

Dentist and practice characteristics associated with restorative treatment of enamel caries in permanent teeth: multiple-regression modeling of observational clinical data from the National Dental PBRN.

Purpose: Current evidence in dentistry recommends non-surgical treatment to manage enamel caries lesions. However, surveyed practitioners report they would restore enamel lesions that are confined to the enamel. Actual clinical data were used to evaluate patient, dentist, and practice characteristics associated with restoration of enamel caries, while accounting for other factors.

Affect Balance and Relationship With Well-Being in Nursing Home Residents With Dementia.

The purpose of this exploratory study was to determine whether the balance of positive to negative affect can discriminate states of well-being in nursing home residents with dementia and whether affect balance is associated with activity engagement. Baseline data from a randomized clinical trial were used in this secondary analysis. Participants were 128 residents recruited from 9 nursing homes located in Pennsylvania.
