Chapter 59 SHORT ANSWERS To prevent dental carries in the pits and fissures Sealants are used primarily on children, but in certain circumstances, adults can benefit from their use. Some maxillary central and lateral incisors may have deep pits that could be protected by sealants. The dental professional must exercise proper patient selection. Sealants are indicated for teeth with deep pits and fissures, preferably in recently erupted teeth (i.e., within previous 4 years). Teeth that are well coalesced (fused together) are less likely candidates for sealants (Fig. 59.4). Premolars are not generally high-risk teeth. Although sealant therapy is aimed at permanent teeth, primary molars may also be sealed to reduce the caries rate and premature tooth loss. Even though the occlusal surface of the primary molars is flatter than that of the permanent molars, sealants are still indicated if deep or stained fissures are found (see Chapter 12). Sealants should be used as part of a preventive program that includes the use of fluorides, dietary considerations, plaque control, and regular dental examinations The cooperation of the patient during sealant placement is very important because proper placement requires a well-isolated, dry field. Patients and their parents should be advised that dental sealants are not a substitute for other caries control measures. Dental sealants
