The greatest area of challenge in primary anterior teeth is the degree of surface decay present. Typically, interproximal and lingual decay sites are found in early childhood caries, formerly termed nursing bottle decay. Restoring these teeth esthetically with composite is a significant challenge for pediatric dentists because these lesions are mostly close to the pulp but not pain & no any pathology seen after radiograph and only extend subgingivally. The diameter of the crown mesio-distally is greater than the length cervico-incisally, which makes the tooth appear wider. The retention of the restoration is compromised by the short crown length .
Resin Composite (Strip) Crowns
Resin composite crowns are the most esthetically desirable anterior restorations for primary anterior teeth but are also among the most technique-sensitive procedures. With crowding of the anterior teeth, it is quite challenging to perform a direct composite restoration. Also, primary teeth are whiter than permanent teeth. Most of the time, shade A1 or Extra White must be used. If in doubt, a tab of composite can be placed on the tooth and light cured to account for the shade changes occurring during polymerization. Once the proper shade has been selected, the process continues using that composite. presents an example of adhesively bonded resin composite (strip) crowns. Preparation design for primary anterior teeth is different from what is needed for permanent anterior teeth because the teeth are small and more amenable to good esthetically desirable results. There should be sufficient incisal reduction (about 1.5 mm) to avoid incisal fracture. In the preferred design, more reduction on the labial surface is required. A small undercut on the facial surface in the gingival third of the tooth is recommended to serve as a mechanical lock. On the lingual surface there is often minimal reduction (about 0.5 mm) and a feather-edged gingival margin.
