Retention and effectiveness of a single application of white sealant after 10 years.

This retrospective cohort study assesses the caries prevalence, cost-effectiveness, and retention of pit and fissure sealant in children living in a fluoridated area 10 years after the single application of a colored sealant to permanent first molars. The status of the sealant and presence of caries or restorations on the sealed teeth was assessed. An age-, gender-, and residence-matched control group of children was examined and similar data were collected for comparison with the sealed group. The cost of a single surface restoration is compared with the cost of sealant application.

Potential uses of pit-and-fissure sealants in innovative ways: a review.

Several independently conducted studies by distinguished researchers in the field have concurred that applying pit-and-fissure sealant to a carious lesion and the adjacent pits and fissures will not result in spread of the lesion. The preventive resin restoration study lacks confirmation, but appears to offer considerable promise. If this technic and the therapeutic sealing of minimal carious lesions are utilized to the fullest extent possible, a great deal of tooth structure will be saved for many patients. The potential future effects of this conservative approach to restorative dentistry could be vast, both individually to patients from a dental health standpoint, and in terms of public and private expenditures for dental health care.

Restoration of a fractured central incisor using original tooth fragment.

A most conservative restorative treatment involving the use of the acid-etch technique and composite resin systems to re-attach the fractured incisal edge of a maxillary central incisor in a 14-year-old boy has been described. As this is a highly conservative treatment, other treatment options still remain open. Esthetic and functional considerations warrant no further treatment at this time. On the basis of previous experience and published reports of clinical trials of similar restorations, it is anticipated that this restoration will remain functional for several, if not many, years. Since the completion of this example, many similar fractures have been restored successfully using a V-shaped notch within the enamel all the way around the tooth, rather than only on the labial surface. This is the preferred method at the present time.
