Results: The results demonstrated that in the occlusal wall, packable composite, showed significantly more marginal microleakage than the other groups.
Conclusion: Based on the results of this study, the use of flowable composite as the first increment is recommended in deep class II cavities.
Materials and Methods : For evaluation, 30 mesiobuccal roots of maxillary molars were selected. Result: It was observed that the manual technique using hand Ni-Ti K-file produced lesser canal transportation and maintained greater dentine thickness than the rotary ProTaper technique at middle and coronal third and this difference was statistically significant.
Conclusion: ProTaper should be used judiciously, especially in curved canals, as it causes higher canal transportation and thinning of root dentine at middle and coronal levels. Materials and Methods: A total of 60 patients, irrespective of sex, in the age group of 15-50 years were selected and the teeth were randomly divided into three groups of 20 each. Results: The patients with restorations cemented with Resin-modified Glass ionomer demonstrated the least postoperative sensitivity when compared with Glass Ionomer and zinc phosphate cement at all different intervals of time evaluated by different tests. Conclusion: The patients with restorations cemented with resin-modified Glass ionomer demonstrated the least postoperative sensitivity.
Results: The FEA revealed that all the post systems showed maximum stress in the coronal and middle third of the root.
Conclusion: The one-step polishing system (PoGo) produced better surface quality in terms of roughness than the multi-step system (Super Snap) for minifill-hybrid composite (Esthet-X), and it was equivalent to Super Snap for packable composites (Solitaire II). Materials and Methods: A microhybrid composite Esthetic -X (Dentsply, Caulk) was used in this study. Statistical Analysis: Data analyzed statistically to determine the significant difference between the groups.
Results: No significant difference in shear bond strength of composites cured with and with out oxygen inhibited layer. Conclusions: The presence or absence of oxygen inhibited layer made no significant difference in shear bond strength of composite resins.

With 200 ng of messenger RNA as starting material, a complement DNA (cDNA) library can be quickly prepared using a straightforward protocol consisting of four major steps using two Roche kits: the cDNA Synthesis System Kit and the GS Rapid Library Prep Kit. The development of bonded restorations in combination with air abrasion dentistry provides a truly minimal intervention dentistry.
Standardized class II cavities were made and were restored using composites of different consistencies with different placement techniques.
In the cervical wall, teeth restored with a flowable composite liner showed less marginal microleakage when compared to all other groups.
Improper preparation can lead to procedural errors like transportation of foramen, uneven dentine thickness, stripping of root canal, formation of ledge, zip, and elbow in curved canals. Of these, 15 roots were distributed into two groups where Group 1 included hand instrumentation with Ni-Ti K-files; and Group 2 comprised ProTaper NiTi rotary system. No significant difference was seen with regard to canal transportation and remaining root dentine at apical levels.
All the models were subjected to a force of 100N applied at 450 to the long axis of the tooth at the middle third of the palatal surface of the restored ceramic crown. Maximum stress was seen on the inner dentinal wall in case of stainless steel post followed by cast gold and carbon fiber post, both in the models without reinforcement as well as in the reinforced models. Minifill-hybrid presented a better surface finish than Solitaire II when PoGo polishing system was used. A cylindrical mold of composite, five mm thick and eight mm long, was prepared and embedded in acrylic resin molds after curing. Mean and standard deviation values were estimated for the study groups and compared by one way ANOVA. Combination of fluoride and ACP-CPP does not provide any additive remineralization potential compared to fluoride alone. The technique also demonstrates the use of a delivery system utilizing large-bore needles for the predictable and precise placement of the barrier materials at the apex of the tooth. The sites of traditional (gene replacement) and novel (enhanced deployment of an active protein) therapeutic interventions are shown. This article reviews the development of air abrasion, its clinical uses, and the essential accessories required for its use. Group 1 with Microhybrid composite, Group 2 with Packable composite, Group 3 Microhybrid composite with a flowable composite liner, Group 4 Packable composite with a flowable composite liner, Group 5 Microhybrid composite with precured composite insert in second increment and Group 6 Packable composite with precured insert in second increment. Pre instrumentation and post instrumentation three-dimensional CT images were obtained from root cross-sections that were 1 mm thick from apex to the canal orifice; scanned images were then superimposed and compared. With regard to centering ratio, no significant difference was seen between both the groups at all levels.
The criteria adapted to measure tooth sensitivity in the present study were objective examination for sensitivity.(1) Cold water test (2) Compressed air test and (3) Biting pressure test.


No significant difference was present in surface roughness between both the materials when Super Snap system was used. The surface layer of composite coming in contact with air forms a superficial sticky layer called oxygen inhibited layer, upon polymerization, allowing resins from both sides to cross the interface and form an interdiffusion zone.
The baseline SMH (surface microhardness) was measured for all the enamel specimens using Vickers microhardness (VHN) testing machine.
Fluoride, ACP-CPP and their combination are not effective in remineralizing the early enamel caries at the subsurface level. This article comes from Madurai in India where its surrounding towns are fluorosis-prone zones. A thorough knowledge of basic root canal anatomy and its variation is necessary for successful completion of endodontic treatment. Specimens then were stored in distilled water, thermocycled and immersed in 50% silver nitrate solution.
The present study was sought to test whether oxygen inhibited layer increases or decreases the shear bond strength at the interface of composites. Artificial enamel carious lesions were created by inserting the specimens in demineralization solution for 3 consecutive days. The purpose of this article is to report various treatment options available for dental fluorosis; this is the first time that complete full mouth rehabilitation for dental fluorosis is being reported. This report points to the importance of looking for additional roots and canals because knowledge of their existence would enable clinician to treat a case successfully that otherwise might end in failure. These specimens were sectioned and evaluated for microleakage at the occlusal and cervical walls separately using stereomicroscope. Polishing systems were applied according to the manufacturer's instructions after being ground wet with 1200 grit silicon carbide paper. This article also dwells on the need for the dentists to be aware of their local indigenous pathologies to treat it in a better manner. Then the four enamel sections of each tooth were subjected to various surface treatments , i.e.
Group 1- Fluoride varnish, Group 2- ACP-CPP cream, Group 3- Fluoride + ACP-CPP & Group 4- Control (No surface treatment).
A caries progression test (pH cycling) was carried out, which consisted of alternative demineralization (3hours) and remineralization with artificial saliva (21 hours) for five consecutive days. After pH cycling again SMH of each specimen was assessed to evaluate the remineralization potential of each surface treatment agent. Then, to asses the remineralization potential of various surface treatments at the subsurface level, each enamel specimen was longitudinally sectioned through the centre to expose the subsurface enamel area.
