    ABSTRACT: This in vitro study assessed the quality of pulpectomies in primary incisors using three filling systems: syringe with plastic needle syringe with metal needle, and lentulo spiral. Preoperative radiographs of sixty extracted primary incisors were taken, canals were prepared and obturated Postoperative radiographs taken in two directions were evaluated by two independent evaluators blinded to the technique used. Filling quality was determined by analyzing radiopacity, presence of voids and amount of material in the canal After statistical analysis, this study showed that NaviTip system offered a more desirable filling quality than lentulo and Vitapex syringe techniques

    ABSTRACT: The purpose of this in vitro study was to determine the effect of crimping and cementation on retention of veneered stainless steel crowns. One hundred twenty crowns, 90 from 3 commercially available brands of veneered stainless steel crowns (Dura Crown, Kinder Krown, and NuSmile Primary Crown) and 30 (plain) Unitek stainless steel crowns were assessed for retention. An orthodontic wire was soldered perpendicular to the incisal edge of the crowns; the crowns were fitted to acrylic replicas of ideal crown preparations and were divided equally into 3 test groups: group 1--crowns were crimped only (no cement used); group 2--crowns were cemented only; and group 3--crowns were crimped and cemented to the acrylic replicas. An Instron machine recorded the amount of force necessary to dislodge the crowns and the results were statistically analyzed using 2-way ANOVA and Tukey honestly significant difference (HSD) test. Group 3 was statistically more retentive than groups 1 and 2. Group 2 was statistically more retentive than group 1 (P < .001). In group 1, Unitek crowns were statistically more retentive than the veneered crowns (P < .05). In group 2, NuSmile crowns showed statistically less retention values than all other crowns (P < .05). In group 3,Kinder Krown crowns showed statistically better retention rates than all other brands (P < .05). Significantly higher retention values were obtained for all brands tested when crimping and cement were combined. The crowns with veneer facings were significantly more retentive than the nonveneered ones when cement and crimping were combined.

    ABSTRACT: A controversial aspect of pediatric dentistry today is parental presence. A number of authors report an increase in the number of parents who wish to accompany their children throughout the dental appointment. Dentists historically have excluded parents from the treatment area, while pediatricians routinely keep the parent and child together. The purpose of this survey was to determine the frequency that Florida pediatric dentists permit parental presence during children's dental visits and to relate the influence of patient age, dentist's years in practice, procedure type, and practitioner attitudes on parental presence. A high return rate (98.9%) was obtained, and results indicated a significant increase in parental presence in the dental operatory and that further increases in parental presence are expected. Younger children were more likely to be accompanied by a parent for each procedure. Parental presence for examination was more likely than for restorative or extraction. Analysis of variance (ANOVA) indicated that the most frequent attitudes influencing the pediatric dentist's choice to exclude parents were that their presence: wastes time (P < 0.001); disrupts the child (P < 0.05); and makes the dentist uncomfortable (P < 0.05).

    ABSTRACT: The acid-etch technique is used extensively in dentistry. Variations in rinse time are found throughout the dental literature. Even though controversies concerning the appropri- ate rinse time exist, all investigators agree that copious water lavage is important. This study compared different rinse times using both liquid and gel etchants labeled with 32Phosphorus. Each etchant type was evaluated on the time necessary to remove the residual soluble and insoluble radiolabel from the human enamel sur- faces. The radioIabeIed etchants were removed in much shorter rinse times than is currently suggested by dental manufactur- ers and investigators.

    ABSTRACT: The purpose of this study was to evaluate the pulpal response to four calcium hydroxide preparations in primary teeth. Data indicated the calcium hydroxide-saline paste induced more inflammation and produced a greater zone of mummification than the three commercial preparations studied. Unintentional deep impaction of the medicament or dentinal chips increased inflammation for all categories. All medicaments produced a superficial necrosis (mummification) of the pulp. The greatest degree of mummification was seen with the calcium hydroxide-saline paste. The calcium hydroxide-saline paste produced a thick dentinal bridge, located deeper in the pulp when compared with the commercial agents. Commercial agents produced narrower but sufficiently high-quality dentinal bridges. This study indicates that direct pulp capping of exposures in primary teeth is a viable procedure. The newer commercial agents may be preferred, as they produce minimal inflammation, satisfactory dentinal bridging, and preservation of most of the vital pulp tissue.

    ABSTRACT: The purpose of this retrospective study was to assess the success of pulpotomies performed on an emergency basis and restored with a temporary zinc-oxide eugenol restorative material. Records were collected from 216 pulpotomies in primary molars performed on an emergency basis by pediatric dental residents at the University of Florida pediatric dental clinic between July 1999 and June 2001. The selection criteria include teeth with a positive history of pain but with absence of clinical and radiographic signs of pulp degeneration. Formocresol was the medicament used and the teeth were restored temporarily with a reinforced zinc-oxide eugenol material. Treatment success or failure was determined, at the definitive restorative appointment, by the presence or absence of clinical and/or radiographic pathology. The time interval between emergency and definitive treatment appointments, tooth-type, arch, age, and gender were the variables analyzed in this study. Chi-square analysis was used to assess the effect of the different variables on the outcome of the treatment. Sixty-four teeth were available for assessment in the two-year period. A 53% success rate was observed, if the tooth was evaluated and restored with the definitive restoration, within the first 90 days post-emergency treatment. A 31% success rate was observed after 365 days. These results were statistically significant (P=0.016). Patients younger than six years old showed statistically significant higher chances for success than older children did (P=0.018). No significant differences were found for gender, type of tooth, or arch. The low success rate found during the first three months post emergency treatment may be attributed to undiagnosed, subclinical inflamed pulp, while long-term failure may be associated with microleakage of the temporary restorative material.
