Effects of surface modification techniques on zirconia substrates and their effect on bonding to dual cure resin cement - An study.

Aim: This study aims to evaluate the effect of different surface treatments of monolithic zirconia on the bond strength of resin to zirconia and, to explore alternative methods to improve this bonding.

Settings And Design: In-Vitro study.

Materials And Methods: Fifty rectangular sintered blocks of Yttria-stabilized Tetragonal Zirconia Polycrystal ceramics of dimensions were milled and sintered.

Anatomic variations of the osteomeatal complex and its relationship to patency of the maxillary ostium: A retrospective evaluation of cone-beam computed tomography and its implications for sinus augmentation.

Aim: The aim of this study is to determine the incidence of obliterated osteomeatal complex (OMC) due to the presence of anatomic variants.

Settings And Design: Retrospective Study.

Materials And Methods: In this retrospective study, a total of 71 patients, 34 males and 37 females, aged 35-65 years were included in the study.

Replicating a discolored tooth preparation: A technique for effective laboratory communication.

Fabricating a ceramic restoration for a discolored anterior tooth presents a clinical challenge. The dental technician is often hampered by being unaware of the shade of the discolored tooth preparation, which influences the color of the overlying ceramic restoration. A definitive cast that replicates the shade of the prepared tooth helps the ceramist to fabricate a restoration that masks the discoloration appropriately and still achieves the desired optical properties.

Effect of newly developed pigments and ultraviolet absorbers on the color change of pigmented silicone elastomer.

Aim And Objective: The aim and objective of the study is to evaluate effect of ultraviolet (UV) stabilizer (UV absorber Chimassorb 81) on color change of pigmented silicone elastomer when commercially available (red and yellow), and newly developed pigments (sicotrans red and sicopal brown) were used.

Materials And Methods: Two commercially available pigments - red (P112 Brilliant Red) and yellow (P106 Yellow) and two newly developed pigments - sicotrans red and sicopal brown were studied. In total eight groups made up of nine samples each were fabricated using elastomer with the combinations of the above pigments and UV stabilizer (Chimassorb 81).

Comparison of photographic and conventional methods for tooth shade selection: A clinical evaluation.

Aim: This study aimed to compare three different methods used for shade selection, i.e., visual method, spectrophotometer, and digital photography method.
