    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: 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.

    ABSTRACT: To evaluate the oral and dental health of Russian children who underwent Frolova primary palatoplasty. Eighty-nine children (62 boys and 27 girls; age range, 5 to 9 years) who had undergone repair of unilateral cleft lip and palate were included in this oral/dental evaluation. Factors such as stage of dentition; oral hygiene; carious, missing and restored teeth; and occlusion were recorded. Twenty-six of the 89 patients presented with a palatal fistula. Oral hygiene of patients without a palatal fistula was significantly better than that of patients with a fistula (p < .01). Forty-five percent of patients had eight or more decayed teeth. Significantly more patients with palatal fistulae had class II soft tissue facial profiles than those without palatal fistulae. Anterior crossbites were found in 48% of patients, unilateral posterior crossbites in 58%, and bilateral posterior crossbites in 12%. The high percentage of poor oral hygiene and dental caries found in this group of patients is likely due to the general unavailability of dental hygiene products and the high cost of these products when available. In addition, it seems there is limited understanding by parents of the importance of dental hygiene and appropriate diet in preventing dental disease.
