Restoring primary anterior teeth.

A variety of esthetic restorative materials are available for restoring primary incisors. Knowledge of the specific strengths, weakness, and properties of each material will enhance the clinician's ability to make the best choice of selection for each individual situation. Intracoronal restorations of primary teeth may utilize resin composites, glass ionomer cements, resin-modified ionomers, or polyacid-modified resins. Each has distinct advantages and disadvantages and the clinical conditions of placement may be a strong determining factor as to which material is utilized. Full coronal restoration of primary incisors may be indicated for a number of reasons. Crowns available for restoration of primary incisors include those that are directly bonded onto the tooth, which generally are a resin material, and those crowns that are luted onto the tooth and are some type of stainless steel crown. However, due to lack of supporting clinical data, none of the crowns can be said to be superior to the others under all circumstances. Though caries in the mandibular region is rare, restorative solutions for mandibular incisors are needed. Neither stainless steel crowns nor celluloid crown forms are made specifically for mandibular incisors. Many options exist to repair carious primary incisors, but there is insufficient controlled, clinical data to suggest that one type of restoration is superior to another. This does not discount the fact that dentists have been using many of these crowns for years with much success. Operator preferences, esthetic demands by parents, the child's behavior, and moisture and hemorrhage control are all variables which affect the decision and ultimate outcome of whatever restorative treatment is chosen.

The clinical and radiographic success of bonded resin composite strip crowns for primary incisors.

PURPOSE: The aim of this study was to examine the clinical and radiographic success of the treatment of maxillary anterior primary incisors with composite resin strip crowns placed in a private practice setting. METHODS: This was a retrospective, clinical study of patients who had strip crowns (SC) placed on maxillary primary incisors, returned for at least 1, 6-month recall examination, and whose parents consented to participate in the study. Radiographic and photographic examinations were used for evaluation. Two evaluators rated the images independently. When ratings were not in agreement, the 2 examiners reviewed the photograph or radiograph together and reached a consensus rating. RESULTS: One hundred twelve restorations placed in 40 children were evaluated. The evaluations were performed after the crowns had been in place for an average of 18 months. None of the restorations were totally lost, and only 12% were rated as having lost some resin material, resulting in an 88% overall retention rate. There was no difference in restoration success if the crowns were placed 4 at a time, or if fewer crowns were placed in a single sitting; the failure rates were comparable. Teeth that had pulpal treatment were judged to have far more significant color match discrepancies than those teeth without pulpal treatment. Ninety-one percent of the teeth demonstrated healthy pulps. Eight percent had some pulpal changes but did not require immediate attention. Only 1 tooth showed radiographic evidence of pulpal necrosis. Only 11 teeth had pulpal treatment, but of these, 10 demonstrated clinical success. CONCLUSIONS: Composite resin strip crowns for restoring primary incisors with large or multisurface caries performed well. Color match of these crowns with adjacent teeth may be significantly reduced when placed upon teeth that have undergone pulpectomy treatment and have been obturated with an iodoform paste. However, based upon the results of this study, the strip crown may provide an esthetic and durable restoration for carious primary incisors.

Parental satisfaction with bonded resin composite strip crowns for primary incisors.

PURPOSE: The purpose of this study was to evaluate the parental satisfaction of bonded resin composite strip crowns for the treatment of maxillary anterior primary incisors and compare their satisfaction with the clinical evaluation and success of the crowns. METHODS: This was a retrospective, clinical study of patients who had strip crowns (SC) placed on maxillary primary incisors, returned for at least 1 recall examination, and whose parents gave consent for them to participate in the study. Color photographs were used for evaluation by 2 independent pediatric dentists. Parental satisfaction regarding the esthetics of the crowns was evaluated by a questionnaire. RESULTS: One hundred and twelve restorations placed in 40 children were evaluated. The evaluations were performed after the crowns had been in place for an average of 18 months (range=6-25 months). Overall parental satisfaction with the treatment was excellent; however, satisfaction with regard to color received the lowest rating. No significant differences were found between dentist and parent evaluations of color, size, and overall appearance (Fisher exact test; P=.194,.776,.291, respectively). Parents rated their overall satisfaction as being positive regardless of their poor ratings of color, size, or overall appearance. However, a significant relationship was found between durability and overall satisfaction (P=.046). Parents who gave poor ratings to durability also rated their overall satisfaction as being poor. CONCLUSIONS: Parental satisfaction with bonded resin composite SCs for the treatment of primary incisors with large or multi-surface caries was excellent. Parents' dissatisfaction was most often related to color of the restorations. However, this did not affect their overall satisfaction with the crowns. The durability of restorations negatively affected the rating of overall satisfaction with the crown. Durability seems to be of more concern than excellent color match to this group of parents.
