Evaluation of Clinical Success, Parental and Child Satisfaction of Stainless Steel Crowns and Zirconia Crowns in Primary Molars.

INTRODUCTION: Stainless steel crowns are the most successful restoration for multisurface carious lesions in primary molars. The esthetics has been poorly accepted which led to the introduction of zirconia crowns. OBJECTIVES: The aim of the study was to evaluate and compare the clinical success, parental satisfaction, and child satisfaction of stainless steel and zirconia crowns in primary molars. METHODS: Thirty healthy patients aged 6-8 years bilateral pulp therapy treated primary molars were randomly divided into two equal groups of stainless steel and zirconia crowns. Tooth preparation was done according to the manufacturers' recommendations depending upon the crown each patient would receive. All crowns were cemented with Type I GIC luting cement. Patients were evaluated at 6 months, 12 months, 18 months, 24 months, and 36 months. RESULTS: Clinical success for stainless steel crowns and zirconia crowns were similar with no statistical difference between them. Zirconia accumulated less plaque than stainless steel crowns (P = 0.047). The parental satisfaction was high with both crowns. A highly significant statistical difference existed between the 2 groups in relation to the acceptance of color (P < 0.001) and child's satisfaction (P < 0.001). CONCLUSION: Zirconia can be considered as an esthetic alternative in the future.

Ten-cusped primary molar tooth: A rare entity with literature review.

Teeth arise by complex and progressive interactions between the ectoderm, oral epithelium and underlying mesenchyme. However, it may show variations and changes in morphological structure. A 6-year-old female child patient came for the treatment of her carious tooth. Intraoral examination revealed supernumerary cusp on occlusal surface of the maxillary right second primary molar. Incidence of supernumerary cusp is a rare condition formed by abnormal proliferation and folding of inner enamel epithelium during morphodifferentiation stage of the tooth development. Conservative cavity preparation and restorative treatment protocol were carried out to treat this case. Early diagnosis, management and timely recall of these rare anomalies will help to avoid potential complications, resulting from faster carious progression in these teeth due to the presence of many fissures and early pulpal extensions into the cuspal area.

A Comparative Evaluation of Revascularization Done in Traumatized Immature, Necrotic Anterior Teeth with and without Platelet-rich Fibrin: A Case Report.

The aim of this paper is to present two methods of revascularization done in traumatized immature, nonvital anterior teeth using platelet-rich fibrin (PRF) and natural blood clot as a scaffold material. This was performed after disinfection of the root canal space using tri-antibacterial paste. In one tooth, PRF prepared from autologous blood was placed in the canal and in the other tooth, natural bleeding was induced to obtain a fresh blood clot. The patient was recalled regularly at 1, 3, 6, 9, and 12 months' interval for evaluation. After 12 months, on clinical examination, both teeth showed negative response to percussion and palpation tests but positive response to cold and electric pulp tests. On radiographic examination, the tooth treated with PRF exhibited comparatively faster root lengthening, complete closure of the root apex, more thickening of the root dentinal walls, and narrowing of root canal space compared to conventionally revascularized tooth.

Efficacy of remineralizing agents to occlude dentinal tubules in primary teeth subjected to dentin hypersensitivity in vitro: SEM study.

AIM: Comparison of casein phosphopeptides (CPPs) and amorphous calcium phosphate (ACP), tricalcium phosphate, and hydroxyapatite on assessment of dentine tubule occlusion on primary enamel using scanning electron microscope (SEM). MATERIALS AND METHODS: A total of 20 freshly extracted noncarious primary molars were randomly divided into four groups (A to D) with five sections in each group; group A: negative control, group B: CPP-ACP, group C: tricalcium phosphate, and group D: Hydroxyapatite (HA). To assess tubule occlusion, 20 dentin sections of 2 mm thickness were obtained from cervical third of sound primary molars. Each section were processed to simulate the hypersensitive dentin and the test agents were brushed over the sections with an electric toothbrush and observed under SEM for calculation of the percentage of occluded tubules. RESULTS: Group B and D showed greater percentage of tubule occlusion than group C. Intergroup comparison of tubule occlusion potential of Group B and D was not significant. CONCLUSION: HA showed significantly higher dentinal tubule occlusion when compared to CPP-ACP and tricalcium phosphate.

A novel approach to regenerate bone loss in an adolescent using concentrated growth factors: One-year follow-up.

Destructive periodontal diseases are rare occurrences in the paediatric population. Moreover, the regenerative potential of the periodontal tissues and supporting structures of teeth is even rare, once irreversible damage has occurred. The aim of this paper is to discuss the regeneration of alveolar bone defect in a 14-year-old using concentrated growth factors (CGF). Following crown removal, scaling, debridement and site preparation, CGF was placed and secured in one-walled defect in the mesial side of the lower right permanent molar. The crown was replaced on to the tooth and the patient was followed up at 1, 3, 6, 9 and 12 months for clinical and radiographic evaluation. After 12 months, the radiographic evaluation revealed the defect to be filled with alveolar bone and probing pocket depth had reduced significantly. Thus, CGF can be an effective agent and can act as a potential scaffold for periodontal regeneration in adolescents with bone loss.
