the aim of this study was to evaluate the marginal adaptation of biodentine in comparison with mineral trioxide aggregate (mta) and intermediate restorative material (irm), as a root end filling material, using scanning electron microscopy (sem).thirty permanent maxillary central incisors were chemo-mechanically prepared and obturated. three millimetres of the root end were resected and 3mm ret...

Internal adaptation of restorations to the cavity wall is one of the important topics in clinical dentistry. The purpose of this study was to investigate the possibility to utilize the non-invasive tomographic imaging system for teaching the importance of cavity adaptation at dental school pre-clinical training. Swept-source optical coherence tomography (SS-OCT) was used for detection of margin...

Aim: The purpose of this in vitro study was to evaluate if the marginal discrepancy and internal fit maxillary complex provisional bridge is improved by either 3D printing or CAD/CAM fabrication technique Methodology: In present a total sixteen samples (Eight each group) fabricated two methods using same STL file. Eight were from Telio CAD Subtractive CAM method (ARUM 5X- 400 Milling machine) (...

STATEMENT OF PROBLEM Fabricating a feldspathic porcelain margin on a metal-ceramic restoration with a clinically acceptable marginal fit has proven to be a technique-sensitive procedure. Pressable ceramics are advocated to solve this problem. PURPOSE The purpose of this in vitro study was to compare the marginal adaptation of a pressable ceramic system when used with both all-ceramic and meta...

Thirty-six patients, 7-13 years of age, demonstrated 96 pairs of contralateral occlusal fissure and bucca] and lingual pit cavities which were restored with a high-copper amalgam. One restoration in each pair was polished with a slurry of XXX-Silex in an unwebbed rubber cup at eight minutes following trituration. The contralateral restoration was finished with assorted pear-shaped Finishing bur...

Composite restorative materials represent a class of unique modern biomaterials since they replace biological tissue in both appearance and function. The early formulations were characterized by problems such as polymerization shrinkage, improper marginal adaptation, inappropriate proximal contact, discoloration or staining also secondary caries. need to improve said properties achieve adequate...

Today, the use of micro-computed tomography is becoming widespread in almost every field dental research. When national review articles on are examined, it seen that focus endodontic and surgical applications. As prosthodontists, our article, which was compiled order to deepen specific usage areas applications studies done this area, provides information about method prosthetic dentistry. Micro...
