Three-year evaluation of sealant: effect of isolation on efficacy.

This study analyzes the clinical effectiveness of a sealant (Delton) and its requirements for retreatment to maintain the optimum protection from pit and fissure caries. One hundred paired occlusal surfaces were treated in 29 patients. Two contralateral, partially erupted, noncarious molars with deep occlusal fissures were randomly selected to receive a sealant; one had a rubber dam and the other, cotton rolls for isolation. Each tooth received a prophylaxis with a rubber cup and a pumice slurry. The dryness of the field was evaluated. Each tooth was etched with 37% phosphoric acid for 60 seconds, rinsed for 15 seconds, and dried for 30 seconds. Sealant (Delton Tinted) was applied with a syringe according to manufacturer's instructions. Sealants were evaluated and reapplied where indicated at 6-month intervals. The average 6-month retention rate over 36 months was 95%, regardless of the method of isolation used when the sealant was applied initially. No tooth under treatment with a sealant became carious. The retreatment rate was highest at baseline (8%) and at 6 months (11.3%). Of the total number of retreated sealants, 61% were from the mandibular arch. During the 36 months of this study, 31% of the treated teeth required at least one retreatment.

The efficacy of the rubber dam as a barrier to the spread of microorganisms during dental treatment.

This study evaluated the rubber dam as an infection control barrier during standard restorative procedures. Microbial collection was performed during preparation and placement of amalgam and composite resin restorations with and without the rubber dam, and during handpiece and air-water syringe spraying with and without the rubber dam. The results showed a significant reduction in microorganisms with the use of the rubber dam--70% to 88% and 95% to 99%, respectively; and 90% to 98% when all data were combined. These results indicate that using the rubber dam is a method of reducing microbial contamination at the primary source. Used with gloves, mask, and protective eyewear, the rubber dam provides an excellent barrier to the potential spread of infectious disease in the dental office.

Glass ionomer-composite sandwich technique.

Glass ionomer cement characteristics of biological acceptability, fluoride release, dentin bondability, and marginal integrity are excellent; at the same time, they have always been regarded as secondary choices for anterior and posterior restorations. Slow set, brittleness, poor finishability, lack of translucency, and the technique-sensitive nature of the glass ionomers hardly compare with the composite resins which are easier to handle, polishable, and esthetically acceptable. The combined ionomer-composite restoration provides a reliable chemical bond to dentin, micromechanical bonding of the composite to ionomer surface, and an acceptable esthetic result.

Evaluating tooth eruption on sealant efficacy.

For patients aged 5 to 9 and 11 to 14, 100 occlusal surfaces on newly erupting permanent molars were treated with a self-curing pit and fissure sealant. All teeth were categorized according to stage of eruption and sealant thickness of the coating applied. After 36 months, 75 surfaces were examined for a final evaluation; 52 surfaces (70%) did not need retreatment. Of the 23 surfaces retreated as a result of sealant loss or marginal deterioration, 18 were retreated only once in the six recall evaluations. Those molars treated originally with the operculum covering the distal marginal ridge of the occlusal surface had twice the probability for retreatment as teeth not treated until the entire marginal ridge was exposed. The thickness of the sealant coating did not affect the early signs of sealant failure.

Teaching the use of bases and liners: a survey of North American dental schools.

The authors surveyed 64 dental schools in North America about their instruction on the use of bases and liners. Respondents cited the materials being taught at the time of the survey, two years before the survey and four years before the survey. There was no consensus as to the materials being used. Copal varnishes and dentin bonding agents, or DBAs, were used most often in Class II preparations more than 2 millimeters from the pulp, and glass ionomers and DBAs were equally popular for Class II preparations within 1 mm of the pulp. Most schools were pleased with the materials they are currently teaching but continue to review material selection annually.

Trends in dental care among insured Americans: 1980 to 1995.

This article presents data on the use of a wide range of dental services by insured patients between 1980 and 1995. The patterns of dental care revealed in this study show clear trends that indicate profound improvements in oral health. These improvements are evident in all age groups, and the effect of the caries decline in children that began about 20 years ago has moved well into the adult population. As those born since about 1950 continue to age and represent an ever-increasing proportion of the population, the overall need for restorative care of all types will continue to diminish.

Teaching Class I and Class II direct composite restorations: results of a survey of dental schools.

The authors surveyed 54 North American dental schools about their teaching programs for posterior composite restorations. Marked variations were noted in the time spent teaching the use of these restorations, their indications and contraindications, and the techniques used for preparing and inserting the restorations. Although the time devoted to teaching placement of posterior composite restorations has increased during the last 10 to 12 years, most recent dental school graduates have minimal clinical experience with Class I and Class II composite restoration.

Evaluating dental office ergonomic. Risk factors and hazards.

Concerns about ergonomic risk factors have been growing among health care and other workers. The authors undertook a study to determine the presence of certain ergonomic risk factors in typical tasks performed by dentists and dental hygienists. They further investigated--by means of electromyography and goniometry--the force, frequency and duration of the task. The study suggests that when a task's duration, force and frequency are accounted for, scaling, polishing, flossing and probing activities do not represent exposure to high ergonomic risk.

Dental cutting: the historical development of diamond burs.

This brief history of the dental diamond bur is intended to provide both a historical perspective and an evaluation of the current state of bur technology. An understanding of the origins of dental diamonds and the issues facing manufacturers transforms the dentist from a simple user into an informed consumer. The author contends that this can improve dental care and enable the dentist to collaborate with manufacturers in developing improved dental burs.
