This manuscript highlights clinical applications of the Tenure dentin bonding agent. Research comparing diametral and bond strengths, and microleakage of Tenure and other dentin bonding agents is presented. The Light-cured Zionomer glass ionomer is shown to provide a superior dentin bond when compared to Vitrabond.
Three patients were treated at birth for low anal deformities and developed intractable constipation, not imputable to usual causes of rectal inertia. Barium enema, done the first time at ten days of age in one case, revealed focal ectasia of the terminal bowel, with a peculiar "balloon-like" aspect of the rectum. Optimal treatment includes resection of the terminal bowel down to the dentate line. Incidence of this anomaly in association with low anal deformities has been 5% in our series.
Both the Rembrandt Whitening System and Quik Start offer a conservative treatment of discolored teeth, with no adverse reactions to hard or soft tissues reported. As well, patient satisfaction has been high.
The conservative technique of professionally dispensed and supervised, home-administered vital bleaching is now a routine treatment in the dental profession. This double-blind study evaluated the Rembrandt Lightening Gel and Whitening Toothpaste for shade change, colorimeter shade change. As well, it evaluated soft tissue health by periodontal probing, plaque index, and bleeding index. A patient questionnaire evaluated perception of whitening, perception of oral hygiene, average hours per day, and average days per week. Bleaching trays were worn over a 4-week period. The bleaching system showed definitive whitening effects as evaluated with the Vita shade guide and the colorimeter. The bleaching system had no deleterious effects on the soft tissue. The Rembrandt toothpaste alone demonstrated two-shade lightening. This vital bleaching system shows definitive whitening of the teeth in short periods of time with no adverse effects.

A multiple case study design is used to explain the level of implementation of a "Heart Health" curriculum by grade four teachers of eight schools in a Montreal multiethnic and underprivileged district. An interview and logbook examine the following variables: 1) personal characteristics of the teachers; 2) organizational characteristics of the schools; 3) characteristics of the program; 4) collaboration between the health and educational sectors; and 5) curriculum level of use and fidelity of implementation. The results show in particular that the personal characteristics of the teachers and the characteristics of the program explain the level of implementation of the Heart Health curriculum.
