The Effect of Different Surface Treatments and Cement Materials on the Bonding between Dentine and Restorative Materials
The aim of this study was to evaluate the effect of different surface treatments and cement materials on the bonding between dentine and restorative materials. In this study, 135 extracted third human molars, three different restorative materials (Cr-Co alloys, composite and zirconia) were used. Acid etching and sandblasting were used the surface of materials and one group was identified to control group. After the surface treatments, restorative materials were bonded to dentine with three cement materials (self-adhesive resin cement, conventional resin cement and glass ionomer cement). The shear bond strength (SBS) test was applied by using a universal testing machine. The statistically analysis of obtained data were performed with use n-way analysis of variance test.The result of n-way analysis of variance test showed that there were statically significant differences either surface treatments or luting cements on the bonding dentine to restorative materials (p=0.001). The results showed that the lowest shear bond value (3.24±3.62 N) was identified in control group of zirconia materials bonded to dentine with glass ionomer cement. The highest shear bond value (94.66±68.36 N) was identified in acid etched composite materials bonded to dentine with conventional resin cement.
Effect of Chlorhexidine Application on Dentin Bond Strength Durability of Two Etch-and-Rinse Adhesive versus a Universal Bond System
Application of matrix-metalloproteinases (MMP) inhibitors such as chlorhexidine (CHX) is capable of reducing bond strength loss over time by preventing collagen fibrils degradation.
Dentin hypersensitivity (DH) is generally described as “a brief, sharp, and acute pain emanating from exposed dentin in response to thermal, tactile, osmotic, or chemical stimuli, as well as exposure to air that cannot be attributed to any dental anomaly or pathology”.
Computed tomography is an alternate imaging modality which can be used to estimate age and to aid on human identification in Forensic Dentistry.
Scanning Electron Microscopic Evaluation of Debris and Smear Layer after Use of Revo-S and CMA Instruments in Straight Root Canals
Biomechanical preparation, disinfection and obturation all together constitute equally important phases of the endodontic treatment. Root canal treatment is based on cleaning, shaping and sealing the root canal system. Its main objectives are the elimination of residual pulp tissue, infected dentine and debris and the reduction of the number of microorganism from root canal system. Many nickel-titanium (NiTi) rotary instruments have been introduced in the last years.
Evaluation of Pumice, Fissure Enameloplasty, Dentin Adhesive and Air Abrasion on Sealant Microleakage
By (1995), Siegel stated that sealants are an important dental caries prevention technology, ideally used in combination with patient education, effective personal oral hygiene, fluorides, regular dental visits. There is a growing need to seal primary molars, as demonstrated by Head Start’s report that found that, for those children who had dental caries, 86% had caries of the pits and fissures of the molars.
Age estimation from tooth – coronal index (TCI) using dental radiographs based on reduction in the size of the dental pulp cavity with advancing age as a result of secondary dentin deposition, has been presented.
Feasibility Analysis of Autogenous Tooth-based Bone Graft Material after Guided Bone Regeneration Technique
We set out to determine the possibility of radiographically evaluating the degree of marginal bone loss in humans after functional loading of implants at sites of guided bone regeneration (GBR) with autogenous tooth-based bone graft (ATBBG) material (AutoBT®, Korea Tooth Bank, Seoul, Korea).
Legal Medical Age Estimation in Portuguese Adult Cadavers: Evaluation of the Accuracy of Forensic Dental Invasive and Non-Invasive Methods
Age estimation of unknown human cadavers is important in setting a crime investigation, such as homicide, suicide or in mass disaster because it can guide forensic investigators to the correct identity among a large number of possible matches. More and more the courts ask for medico-legal age estimations of unknown human cadavers by forensic dentistry.
