An evaluation of recruitment methods utilized for a clinical trial with periodontal and diabetes enrollment criteria: the Diabetes and Periodontal Therapy Trial.

Background: Diabetes and its complications are a major United States public health concern.

Methods: The Diabetes and Periodontal Therapy Trial (DPTT) evaluated whether non-surgical treatment of periodontal disease influenced diabetes management among persons with Type 2 diabetes and periodontitis. The aim of this study was to evaluate DPTT's many recruitment strategies in terms of enrollment success.

Imaging in vivo secondary caries and ex vivo dental biofilms using cross-polarization optical coherence tomography.

Objective: Conventional diagnostic methods frequently detect only late stage enamel demineralization under composite resin restorations. The objective of this study is to examine the subsurface tooth-composite interface and to assess for the presence of secondary caries in pediatric patients using a novel Optical Coherence Tomography System with an intraoral probe.

Methods: A newly designed intraoral cross polarization swept source optical coherence tomography (CP-OCT) imaging system was used to examine the integrity of the enamel-composite interfaces in vivo.

Evaluation of BacT/Alert 3D automated unit for detection of nontuberculous mycobacteria requiring incubation at 30 degrees C for optimal growth.

The reliability of the BacT/Alert 3D unit for automated detection of nontuberculous mycobacteria (NTM) that grow optimally at 30 °C was assessed. This system reliably maintained a temperature of 30 °C and detected 50% of the clinical NTM strains (5 Mycobacterium marinum and 3 Mycobacterium gordonae strains) faster than 37 °C culture.

Interexaminer reliability and clinical validity of the temporomandibular index: a new outcome measure for temporomandibular disorders.

Aims: The operational definitions for the Craniomandibular Index (CMI) were redesigned to conform precisely to those of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD), resulting in a single examination protocol, the Temporomandibular Index (TMI). The objectives were to evaluate interexaminer reliability of the TMI as well as its criteria and construct validity for measurement of TMD severity.

Methods: Interexaminer reliability of the TMI was assessed on 12 subjects.
