Osseointegrated implants placed at supracrestal level may harbour higher counts of A. gerencseriae and S. constellatus - a randomized, controlled pilot study.

Purpose: This study aimed at evaluating the bacterial colonization in dental implants inserted in the crestal or supracrestal position and correlated it to radiographic bone measurements.

Methods: Thirty-five implants with regular platform in nine patients (mean age 62.4±11.

[Virtual learning environment in nursing education: an experience report].

New Technologies of Information / Communication offer the option of using a virtual learning environment (VLE), which allows for greater interactivity in daily nursing education urging educators to rethink their teaching practices. The aim of this study was to report the experience of the use of virtual environment in nursing education from the perspective of students. The discipline "Nursing Education: Trends and Challenges" was given to 78 students from the 4th semester of undergraduate nursing, from which 48 answered a questionnaire with closed and, among these, 33 answered an open question about the use of AVA.

Influence of application site of provisional cement on the marginal adaptation of provisional crowns.

Introduction: Marginal discrepancies may lead to cement washout and marginal leakage, damaging periodontal and pulp tissues or causing premature loss of the restoration.

Purpose: This study evaluated the influence of application site of provisional cement on the marginal adaptation of provisional crowns.

Material And Methods: Four different application sites of provisional cement (Temp Bond NE, Kerr Corporation) were used for cementation of provisional crowns on phantom teeth prepared for full crown restorations, performing 4 experimental groups (n=10): cement applied to all internal surfaces of the crown (CAO); cement applied to all internal surfaces of the crown, except for the occlusal surface (CA); cement applied to the cervical crown margin (CM); and cement applied to the cervical tooth margin (TM).

[Interactive multimedia in nursing: a technology for teaching-learning semiology].

This study was aimed at examining the use of interactive multimedia for the theoretical-practical teaching of Semiology in Nursing It was developed at the Nursing School Alfredo Pinto, Universidade Federal do Estado de Rio de Janeiro, Brazil, from August 2004 to June 2005, with fifth semester students. Opinion forms following the structured interview technique were used to collect the data. The results showed that nursing students think interactive multimedia is an instrument that enhances teaching, making possible the interaction of sounds and images.

Retention of provisional crowns cemented with eight temporary cements: comparative study.

Many temporary cements are commercially available; therefore, it is necessary to indicate them for each clinical requirement with regard to the tensile strength of prosthetic retainers. Thus, the purpose of this study was to compare the retention of provisional crowns cemented with eight temporary cements, over full crown preparations with standardized mechanical principles as height, taper, and length. For that purpose, eighty human first premolars received full crown preparation with standardized height and taper.
