Clinical comparison of sealant and bonding systems in the restoration of fractured anterior teeth

This study compared the clinical performance of the ultraviolet light-initiated fissure sealant and composite system (Nuva-Seal/Nuva-Fil) with a chemically activated system (Adaptic Bonding Agent/Adaptic). A total of 63 fractured permanent anterior teeth involving only enamel and dentin were restored. All teeth were isolated with rubber dams, and the acid etch technique was used. The degree of success was determined from an assessment of retention, marginal integrity, marginal staining, and color change. The restorations were evaluated at 3, 6, 12, 18, and 24 months postoperatively. Of the restorations, 93% were retained in both groups of patients after two years. Varying degrees of marginal problems (lack of marginal integrity or marginal staining) were directly attributable to the extension of the bonding medium and the composite in relation to the conditioned enamel and to each other. Repolishing of the margins should be considered at the time of the recall appointments to improve the quality of restoration.

The fractured anterior tooth: restoration made permanent

Cold-curing resins and enamel etchants are used to restore fractured anterior teeth. It is now possible to restore fractured anterior teeth with cold-curing resins and enamel etchants rather than with the use of extensive cutting and preparation of the tooth. A technique has been devised that demands minimal rotary preparation, and it eliminates the need for pins. This technique increases the durability and longevity of the restoration, and it demands little additional office treatment.

Restoration of Fractured Anterior Teeth with Ultraviolet-Light-Polymerized Bonding Materials: A New Technique

A new restorative material that is polymerized by ultraviolet light is used with a fissure sealant to restore fractured anterior teeth. Tooth structure is not removed in this technique; the fracture site is only cleaned.. After application of a medicament on teeth with near or overt pulp exposures, the fissure sealant is applied and extended to the fractured enamel edge. Enamel surfaces are acid-conditioned and another layer of the sealant is applied. For teeth with near or overt pulp exposures, the placement of the restorative material can be delayed. When the material is placed, it is featheredged to the border of the fissure sealant to provide a leakproof margin. Because the restorative material is shaped before it is polymerized, lengthy finishing procedures are not necessary.

Pulpal response to pin placement

lh e response of the dental pulp to caries or mechanical, thermal, and chemical injury is defense and organization through inflammation.lT5 The extent of injury and potential for repair are primarily governed by the proximity of the irritant to the Pulp* 6-15 The degree of trauma before irreversible or pathologic changes occur is difficult to assess, therefore the dentist must act conservatively during preparation to minimize cumulative trauma beyond the initial injury of the carious invasion. The use of pins in restoring fractured anterior teeth has contributed to conservative restorative procedures minimizing pulp trauma. Teeth with extensive loss of retentive areas can be preserved as vital functioning organs, rather than be extracted. Mechanical considerations of retention and techniques for placement have been covered in many publications.16-21 However, considerations of pulpal response have been neglected. A study wherein threaded pins were placed in the central portion of human pulps at the cervix of anterior teeth and occlusally in premolars indicated virtually no clinical signs or symptoms. 22 A response to cold was the only patient complaint. In this study of 27 teeth, histologic examination showed no necrotic pulps; in the area of the pins, the pulps showed localized necrosis and encapsulation. The object of the following study was to assess the pulpal response to pin placement utilizing the three types of available pins: cemented, threaded, and friction lock. Other considerations were ( 1) the significance of depth, (2) type of cement, and (3) the response to pulp exposure.

Immediate reattachment of fractured tooth segment using dual cure resin

Crown fracture of maxillary anterior teeth is frequent dental injuries for which patients seek immediate dental treatment. Immediate reattachment of the intact fractured tooth segment is a therapeutic choice in such cases. This case report presents one of the best methods used for reattachment, which is an ultraconservative technique. It allows the restoration of original tooth contour, colour and aesthetics.
