Vital Pulp Therapy in Aesthetic Zone-Identifying the Biomaterial That Reduces the Risk of Tooth Discolouration

Abstract

Calcium silicate-based cements are biocompatible materials for vital pulp therapy. However, they discolour the tooth tissue, which is important for the aesthetics of the anterior teeth. The aim of this study was to investigate the effect of calcium silicate-based cements on tooth discolouration. The study included 70 extracted bovine incisors. The crown of the tooth was cut off from the root, 2 mm below the cement–enamel junction. The pulp tissue was removed via a cervical cut with a barbed broach. The teeth were randomly divided into five experimental, one positive, and one negative control groups. The evaluated materials included Biodentine, Ortho MTA, Retro MTA, MTA Plus, MTA Repair HP, and in the positive group, ProRoot MTA. A VITA Easyshade Compact 5.0 spectrophotometer was used before the application, after 1 week, 1 month, 3 months, and 6 months. The significance levels were set at p < 0.05. All materials significantly changed the teeth colour (p < 0.05). However, Ortho MTA, ProRoot MTA, MTA Plus, and Biodentine (ΔE > 6) caused maximum colour change after 6 months. While the ProRoot MTA, Ortho MTA, and MTA Plus caused grey discolouration, Biodentine darkened the shade of the base colour. Thus, Retro MTA and MTA Repair HP can be safely used in the aesthetic dentition zone. According to these clinical results, the possibility of using Biodentine, due to its lack of gray discoloration, can be considered.

Evaluation of the Shear Bond Strength of Four Bioceramic Materials with Different Restorative Materials and Timings

“…Among these bioceramic materials, Mineral Trioxide Aggregate (MTA) is the most widely used in VPT because of its superior physical and chemical properties and its high success rate as reported in multiple systematic reviews and meta-analyses [2][3][4][5][6][7][8]. Despite having superior properties, the staining potential and difficult handling of MTA are considered the major drawbacks [9][10][11][12][13][14][15]. To overcome these drawbacks, several manufacturers have produced newer versions of stain-free MTA and premixed bioceramics.…”

Color Matching of Single-Shade Composite Resin by Various Pulp Capping Materials in Anterior Teeth

“…The blending effect is a term used in esthetic restorative dentistry for the phenomenon where the color difference between the restoration material and the actual tooth appears more pronounced in isolation, but visually appears more esthetically pleasing and harmonious with the natural tooth color upon restoration within the tooth [30]. The blending effect is influenced by various factors, such as the inherent color and translucency of the material, the particle size of the restorative material, surface roughness, and the size of Therefore, additional research that considers this aspect is deemed necessary [3,34,35].…”

Invasive Cervical Resorption of Uncommon Origin: A Case Report With 14-Year Follow-Up

“…The use of bismuth oxide as a radiopacifier or blood contamination are two possible causes of tooth crown staining. Although CSCs are considered to possess a low susceptibility to blood contamination, excessive hemorrhage should be minimized by clinicians as it could adversely affect the setting reaction and the biomaterial's properties [14, 16,17]. Conversely, resin-modified GICs offer an aesthetic appearance and can be polished.…”
