Biocompatibility of Restorative Materials- A Review

“…Lack of pertinent information may call for extra biocompatibility testing, which is frequently carried out using various techniques. Traditional, well-recognized preclinical studies, on the other hand, are mostly appropriate for assessing local irritating effects to oral mucosa, skin tissues, tissues of the pulp and immune mediated reactions [5].…”

Kinetic Study of the Thermal Dehydration of SiO2 and SiO2‐ZrO2 Composites Prepared by Sol–Gel Route

“…Since the middle of the last century biomaterials have gain importance in the various application areas, consequently the research focused its attention on continuously improve biomaterials' performance. [1][2][3] Among the main features required to ensure functionality and durability to a biomaterial, the resistance to corrosion is probably the most important one. [4][5][6] To maintain the biomaterial integrity and avoid the release of undesirable and damaging products the use of protective layers to counteract corrosion phenomena is carried out by using bioactive and biocompatible materials.…”

Reduction of Nickel Ion Release on a TiO₂ Coated onto an Orthodontic Wire

“…Clinically, nickel released from these alloys has been shown to cause adverse tissue reactions and prosthetic loosening [14][15][16][17][18]. Although several studies have reported normal morphology, ultrastructure, viability, and DNA synthesis [19][20][21][22][23][24][25][26], others have reported decreases in DNA synthesis and inhibition of various enzymes of cultured cells when exposed to nickel based alloys [27][28][29][30]. In addition, the superficial corrosion of archwires may affect the friction that appears at the interface between the archwire and bracket, reducing the free sliding action.…”
