ABSTRACT
Introduction: Pit and fissure caries account for about 90% of caries in children and adolescents. Sealant application may be a preventive conservative approach. But it's still challenging to bolster the retention of the filled sealant and to chop back the microleakage. Aim: Aim is to evaluate and compare the microleakage and shear bond strength (SBS) of three filled pit and fissure sealants (PFS) using a subpressure and adhesive system: an experimental analysis. Materials and methods: A total of 90 orthodontically extracted premolars were prepared for microleakage and SBS and divided according to materials and subgroups. Group I: resin-based filled PFS, group II: resin-modified glass ionomer-based filled PFS, and group III: giomer-based filled PFS. Subgroup 1: only sealant application, subgroup 2: subpressure application, and subgroup 3: adhesive system + subpressure application. Samples were subjected to thermocycling. Microleakage was assessed with a dye penetration method under a stereomicroscope, and SBS was assessed with a universal testing machine. Statistical analysis and results: Unpaired t-test and one-way analysis of variance (ANOVA) test were used for analysis. Significant when p < 0.05. The SBS showed significant results for subpressure application and giomer-based filled PFS with p < 0.05. The microleakages score differed significantly for the subpressure application group with p < 0.05. Giomer-based filled PFS showed the least microleakage score. Conclusion: This study concluded that giomer-based filled PFS showed statistically significant results. The subpressure technique significantly reduces microleakage and increases SBS.

ABSTRACT
Aim: To evaluate and compare for remineralization potential of enamel at three different time intervals using commercially available MI Varnish and Duraflor Halo varnish [5% sodium fluoride (NaF) varnish] incorporating bioactive glass, dicalcium phosphate dihydrate (DCPD), and biomimetically modified mineral trioxide aggregate (MTA). Materials and methods: For the study, a buccolingual division into equal halves was done for 64 decoronated premolar crowns. Among these 64 crowns, we mounted 32 in acrylic discs to be used for microhardness and induced white spot lesions (WSLs) measuring 5 × 5 mm on the exposed enamel surface. These samples were divided into four groups of 24 each depending upon the varnish used. Varnish application was done, followed by immersion of these samples for 24 hours in artificial saliva, followed by peeling off of varnish. A pH cycling of 28 days was done after the varnish application before assessing the remineralization of the samples. Evaluation of all these samples was done at three different time intervals, baseline, after demineralization, and post remineralization for microhardness on the enamel surface. Raman spectroscopy was utilized for the measurement of phosphate (P) ion release. Sectioning of these samples to a thickness of 100 µm approximately was done to be viewed under a polarized light microscope. Results: Bioactive glass incorporated varnish showed the highest microhardness values, mineral content levels, and least depth of lesion posttreatment. Conclusion: All the experimental varnish showed significant remineralizing potential with the best potency seen with bioactive glass incorporated varnish. Clinical significance: The nonfluoride agents can be appropriately used in 2 wt% amount to augment the benefits of fluoride. How to cite this article: Hardikar AS, Gaonkar NN, Devendrappa SN, et al.

ABSTRACT
AIM AND OBJECTIVE: This article aims to report a case of Sturge-Weber syndrome (SWS) in a pediatric patient and its systematic dental management to add to the existing literature. BACKGROUND: Sturge-Weber syndrome is one of the vascular disorders, known for its stupendous scope of clinical manifestations and life-threatening complications. The substantial prevalence of oral manifestations in SWS makes it crucial to have a comprehensive knowledge of this rare congenital disorder. CASE DESCRIPTION: This case report represents a case of SWS in an 11-year-old boy with oral, ocular, and neurological features who reported due to pain, unilateral gingival enlargement associated with spontaneous bleeding in the mandibular left region. A multidisciplinary team approach having comprehensive knowledge regarding such rare congenital disorder is a must to prevent its life-threatening complications. CONCLUSION: Sturge-Weber syndrome often affects the oral cavity through vascular lesions. Hence, deep knowledge is immensely important to provide an appropriate dental treatment without complications. CLINICAL SIGNIFICANCE: Port-wine stains should not be considered as just birthmarks and should be further investigated for its systemic involvement to arrive at a confirmatory diagnosis and treated accordingly with special precautions.
