The need of good dental materials makes the material scientists to continuously experiment and innovate new materials. There are three basic requirements of a material i.e. they should have good mechanical properties, esthetic properties and should be bio-compatible. Polyether Ether Ketone (PEEK) is very close to satisfy all these properties for which it has been used in numerous clinical situations. This article is a review of properties, utility in conventional situations and additive manufacturing and about the limitations of PEEK, as a dental material.Keywords

Bioactive restorative materials are the latest and the newest subjects of extensive studies and research in dentistry. It is not synonymous with biocompatible restorative materials. In the older times, research on biocompatibility was very much on the high, but in the recent times, research on bioactivity of restorative materials is on the rise. The interaction between dental pulp and these materials, its regeneration and healing are the major areas of interest.Keywords

Cleft defects are very common deformations in the head and neck region. This requires immediate intervention by specialists from birth. Counseling patient and family members from the initial period is vital. Treatment is done phase by phase. There have been various factors affecting prevalence of this defect. This article is a review of the epidemiology of cleft defects, observed in different regions and in India.Keywords

Purpose: The purpose of this study is to evaluate the ability to accurately record, maintain and reproduce vertical interocclusal relationship of four bite registration materials i.e. (Aluwax, zinc oxide eugenol, polyvinylsiloxane, bisacrylic resin bite registration materials).
Statement of problem: It is necessary to evaluate recording materials for their accuracy to record, maintain and reproduce these maxillo-mandibular relationships as they are transferred from the mouth to the articulators.
Materials and method: Maxillary & mandibular cast were articulated in maximum intercuspation in split cast technique on the Whipmix articulator. This position was adopted as reference position for displacement measurement of the four materials. Two arbitrary points are selected on the right and left side of the cast to avoid operator tendency of repetition of the value. The measurements were calculated as the difference between the readings of the two points. The interocclusal records were placed and the measurements were taken. The difference in the two reading gave the vertical discrepancy with each material.
Results: ANOVA and Tukey test were used. The result was statistically significant. Wax plus zinc oxide eugenol and wax plus aluwax showed significant difference statistically & clinically in recording the relationship.
Conclusion: The bisacrylic resin and polyvinylsiloxane bite registration materials can record the interocclusal relationship accurately. Wax plus zinc oxide eugenol paste and wax plus aluwax produced significant discrepancies in recording the relationship.
