Surface Characteristics of Tooth and Effectiveness of Diamond Points: A Systematic Review

Cutting efficiency of dental burs is sparse and inconsistent. Difficulty maintaining constant handpiece speed torque and controlled water spray action lack sufficient test materials mimic dental hard tissue. Diamond burs provided by manufacturers to dentists is coarse grit diamond burs with higher cutting rates. Medium grit burs favoured cutting instruments. Coarse grit diamond burs induce cracks in enamel while cutting.Diamond burs have one or more layers of diamond chips attached to the shank that get inserted into the hand piece. The shank is fabricated of high strength metal usually stainless steel, the working end or the cutting end of the shank is machined to specific shape or blank where diamond chips are attached. Therefore, the aim of this review is to determine the surface characteristics of the tooth and effectiveness of diamond points when prepared with different company products with subsequent usage. The study setting of this research is scoping review. The approval from the research committee was not required since it is a review. The minimum no. of articles are 18. In our research we reviewed a total of 50 articles. The sampling and data collection done by search engines such as PUBMED, Google scholar, bioRxiv, medRx, chemRxiv, CON, Mesh and from various journals of prosthodontics. The period of duration considered was upto2018. Diamond burs are the usual rotary instruments used for many restorative procedures such as cavity preparation for direct and indirect restorations, enameloplasty, grinding and polishing of definitive restorations and removal of defective restoration. A proper tooth preparation is essential for aesthetics, acceptable prosthetic rehabilitation, fracture resistance and healthy soft tissues. Dental burs are most commonly used instruments during clinical and laboratory procedures. Medium grit burs favoured more of the cutting instrument. Coarse diamond grit burs induced cracks in enamel cutting. Dental cutting diamond burs are heavy handed and light touch. Damage to the enamel subsurface in tooth preparation can be caused by diamonds.
