To Premedicate or Not to Premedicate – That is the Question!

Dr. Nicolucci is president of the Canadian Society of Oral Implantology and is Oral Health magazine's editorial board member for Implantology.

Prophylactic antibiotic coverage has been a very controversial topic in the profession over the years.

The management of dental decay, its detection, assessment and treatment, is one of the cornerstones of dental practice. The dentist and hygienist spend each workday dealing with the results of the caries process and yet, until recently, we have not had a scientific, accurate, reproducible and clinically significant way to detect the extent and severity … Read more

Successful Light Curing – Not As Easy As It Looks

Figure 10B. Nanohybrid composite resin light-cured in a translucent cylindrical matrix holding the light at a 45 degree angle and within 0.5-mm distance to the top surface of the cylinder-note incomplete depth of cure for the length and the angle due to the position of the curing light (20 seconds of light-curing with LED curing light measured at 1200 mW/cm2).

Dentists assume that activating a light-curing device reliably and predictably light cures restorative materials. There are many factors that must be considered when light-curing resin adhesives, resin-based composites, resin cements, etc., to ensure the quality and durability of the restorations being placed. Clinicians have choices in the light-curing devices they use. Despite appearances that all … Read more

Wireless Digital Sensors

When digital dental radiography was first introduced in the late 1980s, conventional X-rays had been used for almost a century. Over the years, the radiograph expanded the dentist’s investigative capacity in many ways; it was possible to confirm health, or to detect disease, in many previously invisible areas of concern to the profession including coronally, … Read more

Incandescent to Halogen to Diode: The Evolution of Visual Diagnostics

Figure 10. Illumination at higher level.

Lighting technology has evolved dramatically over the past century. With the introduction of gas and incandescent lighting, dentists were finally able to shed some light on the teeth that they were treating. The illuminated visual access enhanced diagnosis and facilitated more precision in dental procedures. As the use of light-focusing bulbs and light-reflective surfaces matured, … Read more

Bruxism/Snoring Monitor: Measure, Analyze, Categorize and Treat

Figure 4. Report summarizes a patient successfully treated with an oral appliance and no significant bruxism needed.

The diagnosis and management of dental disease implies an effort by the practitioner and the dental team to identify and assess the problem as early as possible. This is consistent with the generally accepted principle that early treatment is likely the most conservative, least invasive, and most likely to achieve optimal results for the patient. … Read more
