Comparison of shear bond strength of amalgam bonded to primary and permanent dentin.
(49/103)
Amalgam's non-adhesive characteristics necessitate cavity preparations incorporating retentive features, which often require the removal of non-carious tooth structure. Use of adhesives beneath amalgam restorations, would be helpful to overcome this disadvantage. This study was undertaken to compare the mean shear bond strength of amalgam bonded to primary and permanent dentin, to evaluate the efficacy of amalgam adhesives in pediatric dentistry.27 primary and 28 permanent posterior teeth with intact buccal or lingual surfaces were grounded to expose dentin and wet-polished with 400-grit silicone carbide paper. Scotchbond Multi Purpose Plus adhesive system was applied to the dentin surfaces and light cured. Amalgam was condensed onto the treated dentin through a plastic mold.shear bond strength testing was done using an Instron Universal testing machine, at a crosshead speed of 0.5 mm/min.The data were analyzed by independent samples t-test The difference among the two groups was not statistically significant (p>0.05) Bonded amalgam showed the same level of bond strength to primary and permanent dentin; so, application of amalgam bonding agents in pediatric dentistry can be recommended.

First-year students' perceptions about pediatric dental behavior guidance techniques: the effect of education.
(50/103)
The purpose of this study was to evaluate the effect of a dental education component on dental students' perceptions toward behavior guidance techniques in pediatric dentistry. A questionnaire was completed by seventy-three first-year dental students, before and after a course on human development and behavior guidance techniques in pediatric dentistry. The acceptability of behavior guidance techniques and situations in pediatric dentistry was scored with a visual analog scale before and after the course, compared, and evaluated in relation to demographic data. After the course, statistically significant increases (ANOVA) in the acceptability of aversive behavior guidance (voice control, hand over mouth, and immobilization), sedation, general anesthesia, and modeling were found. Statistically significant decreases (ANOVA) in acceptability were found in mentioning the possibility of pain during treatment and with a parent being in the clinic or talking with the child during treatment. Female or married students, those who had previously received dental treatment, or those who had a dentist in the family showed statistically significant changes that indicated more empathy toward the children. We conclude that undergraduate dental education may have a significant short-term influence on dental students' perceptions of behavior guidance in pediatric dentistry. (+info)

Factors influencing pediatric dental program directors' selection of residents and demographics of current directors.
(52/103)
The primary goal of this study was to examine the criteria that influence rankings of candidates by advanced education program directors in pediatric dentistry. Secondary objectives were to obtain information on the resident selection process and to explore demographics of current program directors. A survey was sent in 2005 to all sixty-three program directors of pediatric dentistry residency programs accredited within the United States for the graduating class of 2007. The survey had a response rate of almost 78 percent (49/63). Respondents were requested to rank the importance of eleven factors that are typically included in the selection criteria for pediatric dentistry residents. Factors were rated on a scale of critical, very important, fairly important, somewhat important, and not important. The four highest ranked criteria by program directors were the following, in order: National Board scores, dental school clinical grades, class rank, and grade point average (GPA). Other factors ranked in descending order of perceived importance were the following: dental school basic science grades, experience in pediatric dentistry, extracurricular activities, completion of a general practice residency or advanced education in general dentistry program, the application essay, a publication or professional presentation, and private practice experience. All directors ranked personal interviews as very important to critical. Letters of recommendation from a pediatric dentistry department chairperson or faculty member were viewed more favorably than letters from dental school deans and non-pediatric dentistry faculty. Fifty-seven percent of the directors responding (28/49) were male, and 81 percent (40/49) were white, non-Hispanic. Fifty-nine percent of the directors (29/49) graduated from a residency program over twenty years ago, with 39 percent (19/49) having been a director for less than five years. (+info)

Techniques for managing behaviour in pediatric dentistry: comparative study of live modelling and tell-show-do based on children's heart rates during treatment.
(55/103)
BACKGROUND AND OBJECTIVES: Tell-show-do is the most popular technique for managing children"s behaviour in dentists" offices. Live modelling is used less frequently, despite the satisfactory results obtained in studies conducted during the 1980s. The purpose of this study was to compare the effects of these 2 techniques on children"s heart rates during dental treatments, heart rate being the simplest biological parameter to measure and an increase in heart rate being the most common physiologic indicator of anxiety and fear. MATERIALS AND METHODS: For this randomized, controlled, parallel-group single-centre clinical trial, children 5 to 9 years of age presenting for the first time to the Saint Joseph University dental care centre in Beirut, Lebanon, were divided into 3 groups: those in groups A and B were prepared for dental treatment by means of live modelling, the mother serving as the model for children in group A and the father as the model for children in group B. The children in group C were prepared by a pediatric dentist using the tell-show-do method. Each child"s heart rate was monitored during treatment, which consisted of an oral examination and cleaning. RESULTS: A total of 155 children met the study criteria and participated in the study. Children who received live modelling with the mother as model had lower heart rates than those who received live modelling with the father as model and those who were prepared by the tell-show-do method (p < 0.01). The model used for live modelling (father or mother) and the child"s age were determining factors in the results obtained. CONCLUSIONS: Live modelling is a technique worth practising in pediatric dentistry. (+info)
Evaluating the need for alternative didactic learning options in pediatric dental residency training.
(56/103)
The need for an alternative means of delivery of a didactic curriculum to pediatric dental residents is described. It is our hope with this project to encourage a much-needed didactic curriculum for programs lacking faculty and to endorse other programs in which academicians exist but cannot cover all the material with which a resident needs to become familiar in the two years of postgraduate residency training. A decrease in faculty number due to retirement, debt burden, or marginal recruitment techniques along with an increase in positions in pediatric dentistry residency programs poses a unique educational dilemma. Using a mixed-method research methodology, we sent a twelve-question survey to 105 pediatric dentistry residency program directors and department chairs, followed by eight telephone interviews. Results from a 55 percent return rate show that the debt burden of most pediatric dental residents is well over $100,000 and that this affects a resident's decision to enter academia, as does the relative lack of positive recruitment techniques and poor faculty remuneration. The survey results affirm the need for improvement in the didactic curriculum of pediatric dentistry residents and show that program directors and department chairs also feel that an alternative delivery method using DVD or online/web-based programs would be welcomed. Despite their extremely heavy workloads, educators are willing to contribute by providing lectures or reading lists in their area of expertise. (+info)
