Evaluating the impact of interprofessional forums on dental medicine students' collaborative practice skill perception.

Purpose: This study evaluates third-year dental medicine students' perceived competencies related to interprofessional collaborative practice (IPCP) after completing two exposure level experiences with students from other professions across a large academic health center.

Methods: Two cohorts of D3 dental medicine students (2018-2019 and 2019-2020) completed the Interprofessional Collaborative Competencies Attainment Survey (ICCAS) after participating in in-person 2.5-h Interprofessional (IP) Forums in the Fall and Spring semesters.

Creating a Film to Teach Health Professions Students the Importance of Interprofessional Collaboration.

To produce, implement, and evaluate the effectiveness of a film to develop the foundational knowledge and skills of health professions students and teach them the importance of interprofessional collaboration. An existing interprofessional case study about a Hispanic man suffering from multiple chronic health conditions and the impact his health had on his family served as the basis for the film. To ensure a high-quality production, faculty members partnered with a local theatre company to produce the film.

Using Standardized Patients to Teach Interprofessional Competencies to Dental Students.

The aims of this study were to develop, implement, and evaluate a novel interprofessional standardized patient exercise (ISPE) with oral-systemic and interprofessional collaborative practice (IPCP) components. Dental students and doctor of nursing practice (DNP) students at one U.S.

Effectiveness of an infiltrant on sealing of composite restoration margins with/without artificial caries.

Aim: The aim of this in vitro study was to evaluate the effectiveness of a resin infiltrant (ICON) on marginal sealing ability of class II resin restorations with/without-caries.

Materials And Methods: Forty-eight noncarious human pre-molar teeth were embedded and MO and DO preparations of standard dimensions were prepared. The left side of dentin margins of the cavities were left nonbonded (UB) while the right side were bonded using total etch-bonding agent and all restored with a Nanohybrid composite.

Effect of resealing on microleakage of resin composite restorations in relationship to margin design and composite type.

Objective: To determine the relationship between margin preparation design and resin-composite type on microleakage with or without re-application of surface-penetrating sealant.

Methods: Class-I resin-composite restorations were completed for 128 extracted human molars. Half of the margins were beveled, the other half, butt-joint.

Bond strength of one-step self-etch adhesives and their predecessors to ground versus unground enamel.

Objective: The aim of this study was to compare the shear bond strength of several self-etch adhesives to their two-step predecessors to ground and unground enamel.

Methods: Seventy-five extracted, non-carious human third molar teeth were selected for this study. The buccal surfaces of each tooth were mechanically ground to obtain flat enamel surfaces (ground enamel), while the lingual surfaces were left intact (unground enamel).

Effect of laser preparation on bond strength of a self-adhesive flowable resin.

The aim of this in vitro study was to evaluate the effect of laser treatment on shear bond strength of a self-adhesive flowable resin composite to human dentin. Eighty extracted sound human molar teeth were used for the study. The teeth were sectioned mesiodistally and embedded in acrylic blocks.

Twenty-four month clinical evaluation of fissure sealants on partially erupted permanent first molars: glass ionomer versus resin-based sealant.

Background: Glass ionomer sealants are an alternative to resin-based sealants, especially for use in partially erupted permanent molars. The authors conducted a study to compare the retention, marginal staining and cariostatic properties of a glass ionomer sealant with those of a resin-based sealant during a 24-month period.

Methods: We included in this study 39 patients aged 5 through 9 years who had bilateral partially erupted first permanent molars.

Effects of different cavity disinfectants on shear bond strength of a silorane-based resin composite.

Aim: This in vitro study evaluated the effect of different cavity disinfection agents on bond strength of a silorane-based resin composite.

Materials And Methods: Thirty-six caries-free human third mandibular molars sectioned in mesio-distal direction were mounted in acrylic resin with their flat dentin surfaces exposed. After the dentin surfaces were wet ground with # 600 silicon carbide paper, the teeth were randomly divided into 6 groups of 12 each according to the cavity disinfection agents; chlorhexidine (CHX); sodium hypochlorite (NaOCl), propolis, ozone, Er,Cr:YSGG laser and no treatment (control).

Comparison of the effects of Er,Cr:YSGG laser and different cavity disinfection agents on microleakage of current adhesives.

The aim of this study was to compare the effect of the Er,Cr:YSGG laser and different cavity disinfection agents on microleakage of an etch-and-rinse and a self-etch adhesive. Class V preparations were completed on the buccal and lingual surfaces of 30 extracted noncarious human molars. The occlusal margin was placed on enamel and the gingival margin on dentin.

Comparison of different finishing/polishing systems on surface roughness and gloss of resin composites.

Objectives: The aim of this study was to compare four finishing/polishing systems (F/P) on surface roughness and gloss of different resin composites.

Methods: A total of 40 disc samples (15 mm × 3 mm) were prepared from a nanofill - Filtek Supreme Plus (FS) and a micro-hybrid resin composite - Esthet-X (EX). Following 24h storage in 37°C water, the top surfaces of each sample were roughened using 120-grit sandpaper.

Comparison of the Er,Cr:YSGG laser with a chemical vapour deposition bur and conventional techniques for cavity preparation: a microleakage study.

The aim of this study was to compare the effects of the Er,Cr:YSGG laser using chemical vapour deposition (CVD) bur cavity preparation with conventional preparation methods including a diamond bur and a carbide bur on the microleakage with two different adhesive systems. A total of 40 extracted human premolars were randomly assigned to four experimental groups according to the cavity preparation technique: group I diamond bur (Diatech); group II carbide bur (Diatech); group III Er,Cr:YSGG laser (Biolase Millennium II); and group IV CVD bur (CVDentUS). Using the different preparation techniques, Class V standardized preparations were performed on the buccal and lingual surfaces with gingival margins on the dentin and occlusal margins on the enamel.

Thermal safety of Er:YAG and Er,Cr:YSGG lasers in hard tissue removal.

Objective: The aim of this study was to compare the thermal safety of Er:YAG and Er,Cr:YSGG lasers with conventional multi-use and single-use diamond burs.

Background Data: Thermal effect of tooth preparation is mostly evaluated through the pulp chamber because it is difficult to measure the temperature of the preparation surface. A new in vitro method was introduced to simultaneously evaluate the heat increase of the preparation surface together with the pulp chamber.

Should my new curing light be an LED?

The new generation LED curing light units have significantly improved curing performance compared to first generation lights, and even some second generation LED curing light units. This study compared the curing performance of 10 new generation LED light curing units (FLASH-lite 1401, LE Demetron 1, Coltolux, Ultra-Lume 5, Mini LED, bluephase, Elipar FreeLight 2, Radii, Smartlite IQ and Allegro) for depth of cure against a high-powered halogen curing light unit (Optilux 501). Depth of cure measurements were utilized per the ANSI/ADA No 27 standard to detect differences between the lights at three time intervals (10, 20 and 40 seconds).

Surface protection for newly erupting first molars.

The objective of this study was to compare the retention of GC Fuji Triage glass-ionomer to Delton FS+, a resin-based sealant on saliva-contaminated enamel surfaces. Seventy-two extracted noncarious human permanent molars were divided into 3 groups for sealing using Triage (T), Delton FS+ with Prime & Bond NT (DP), and Delton FS+ (D) alone. After prophylaxis with pumice, Groups D and DP were etched with 38% H3PO4 for 30 seconds.
