Using air-abrasive technology to diagnose and restore pit and fissure caries

Article Abstract:

Air abrasion technology may help dentists diagnose and treat decay in the pits and grooves of teeth. Air abrasion uses a pressurized stream of microscopic powder to rapidly remove tooth matter. Dark stains in the pits or grooves of teeth may mask cavities. Dentists can use air abrasion to remove the discoloration. Cavity-free areas can be treated with resin sealants to prevent decay. If cavities are detected, the dentist can use the air abrasion system to remove the lesions. The tooth can be filled with a glass ionomer cement, a composite resin or sealant, an adhesive bonding agent, or other material. Because the dentist controls the air abrasion instrument, small amounts of material can be removed while retaining nearly all of the healthy tooth structure. Patients are comfortable during the air abrasion procedure and benefit from early intervention.

Modern management of dental caries: the cutting edge is not the dental bur

Article Abstract:

A medical model for treatment of dental caries proposes emphasizing the elimination of the bacteria that cause caries rather than focusing on treatment of the resulting cavities. Both Streptococcus mutans and lactobacilli have been identified with dental caries. The medical model works by defining a goal and ending treatment when that goal is achieved. In this case, the first step would be the identification of those patients at risk for developing dental caries. The next step would be treatment to eliminate the cavity-causing bacteria. This treatment involves several steps including restoring and sealing the infected areas and treating with antimicrobials, usually in a prescription mouthwash. When the bacteria has been eliminated, the patient is dismissed from treatment and followed-up regularly to monitor any signs of reinfection.

Caries prevention: current strategies, new directions

Article Abstract:

Despite a drop in the incidence of tooth decay, many teenagers still have new or existing cavities, or caries. There are several ways to reduce the incidence of caries. One is to give people at high risk a vaccine against the bacterium primarily responsible for caries, Streptococcus mutans. However, vaccines are still in the experimental stage. Dietary modifications that reduce the consumption of sucrose can be helpful. Water fluoridation or the direct use of fluoridated toothpaste can increase tooth resistance. Polymer coatings and laser light can also strengthen teeth.
