Background:
The authors conducted a study to survey the perspectives of dentists regarding the 2010 American Dental Association (ADA) recommendation to seal non-cavitated carious lesions (NCCLs) in children and young adults.
Methods:
The authors mailed a questionnaire to a randomly selected sample of 2,400 general dentists (GDs) and pediatric dentists (PDs) in the United States. The sample was chosen by the ADA's Survey Center. The questionnaire included two photographs of NCCLs (permanent first molar and premolar) in a 12-year-old child. Respondents were provided with radiographic findings and asked to choose from several management options.
Results:
In the absence of radiographic evidence of caries, 37.4 percent and 42.3 percent of GDs and PDs, respectively, indicated that they would seal the NCCL in the molar. For the premolar, a significantly lower percentage of GDs than of PDs indicated that they would seal the NCCL. With radiographic evidence of caries in dentin, less than 4 percent of all dentists surveyed indicated that they would seal the NCCLs, and more than 90 percent indicated that they would remove the caries and place restorations. Less than 40 percent of dentists indicated that they sealed NCCLs in their practice.
Conclusions:
The U.S. dentists surveyed have not adopted evidence-based clinical recommendations regarding the sealing of NCCLs. Practice Implications. New educational and dissemination programs should be developed regarding these evidence-based caries management approaches.

Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...
Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
Local Anesthetics: Common Agents and Their Applications
Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...
Local Anesthetics: Clinical Application as Surface, Infiltration, and Conduction Block Anesthesia
Local Anesthetics: Clinical Application as Epidural Anesthesia
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
