“…For this reason, the C 12 A 7 phase may be used to control the hardening and to produce commercial brands of calcium aluminate‐based cements with faster setting‐time 42 . This darkening potential in not completely understood yet; however, it could be suggested that the strong hydration kinects and the faster setting reaction promoted by the C 12 A 7 phase led to a lower uptake of staining substances from the medium 43,44 …”

Objectives To assess the discoloration of teeth treated with the different phases of calcium aluminate cement (CAC), in comparison with the conventional CAC and mineral trioxide aggregate (MTA). Materials and methods Fifty bovine incisors were prepared and filled. Two millimeters of the filling was removed to fabricate a cervical plug with the following cements (n=10): CA(CaO.Al2O3); CA2(CaO.2Al2O3); C12A7(12CaO.7Al2O3); CAC and MTA. The initial color measurement was performed and after 7, 15, 30, 45, 90, 180, and 365 days new color measurements were performed to determine the color (ΔE00), lightness (ΔL'), chroma (ΔC'), hue differences (ΔH'), and the whiteness index (WID). Results ΔE00 was significant for groups (p = 0.036) and periods (p < 0.05). The greater ΔE00 was observed after 365 days for CAC (12.8). C12A7 (7.2) had the smallest ΔE00. ΔL' and ΔC' were significant for groups and periods (p < 0.05). ΔH' was significant for periods (p < 0.05). After 365 days, significant reduction in lightness was observed for all groups. For CA, CA2, CAC, and MTA groups, the WID values decreased over time (p < 0.05). Conclusions The tested cements changed the color behavior of the samples, resulting in greater teeth darkening over time. Clinical significance There is no long‐term study assessing the discoloration induced by the different phases of CAC.

“…This procedure has been indicated by the International Association of Dental Traumatology (Bourguignon et al, 2020) involving the amputation of 2-3 mm from the exposed pulp, followed by placement of the biomaterial over the remaining coronal pulp and composite restoration. Despite its benefits of continuing deposition of cervical dentine and reduction of root canal obliteration (Elmsmari et al, 2019), there is a concern about possible staining promoted by new materials in contact with the blood in the crown (Chen et al, 2020). Therefore, the present study aimed to mimic a complicated crown fracture in an incisor treated by partial pulpotomy using BCT or BCR compared to BD, which is currently recommended as the material of choice for VPT for aesthetic purposes (Camilleri, 2015).…”

Biological parameters, discolouration and radiopacity of calcium silicate‐based materials in a simulated model of partial pulpotomy

Aim To analyse the discolouration, radiopacity, pH and calcium ion release of Biodentine (BD), Bio‐C repair (BCR) and Bio‐C temp (BCT), as well as their biological effects on human dental pulp cells (hDPCs). Methodology Sixty‐four extracted bovine incisors were prepared to simulate crown fractures with pulp exposure and open root apex. The roots were filled using a mixture of agar and blood (control), and BD, BCR or BCT were placed over this mixture. Colour assessment analyses of the samples were performed before and immediately after material insertion and repeated at 30 and 90 days, using a spectrophotometer. The colour change of each specimen was evaluated at the crown and calculated based on the CIELab colour space. Digital radiographs were acquired for radiopacity analysis. hDPCs were placed in contact with different dilutions of culture media previously exposed to such materials and tested for cell viability using the MTT assay. The pH and calcium ion release of all materials were measured after 24 h; the data were assessed using one‐way analysis of variance (ANOVA). Cell viability was analysed by two‐way ANOVA. Differences in colour parameters and wound‐healing data were assessed by two‐way repeated measures ANOVA (α = 0.05). Tukey's and Dunnett's tests were used to compare the experimental groups with the control group. Results BCR had grater radiopacity and smaller colour alteration (ΔEab/ΔE00) than the other materials tested (p < .005; p < .001). No significant differences in pH were found amongst the tested materials (p > .05). BCT was associated with the largest release of calcium ions (p < .0001). BD had cell viability similar to that of the control at the lowest dilutions, and BCR was similar to that of the control, regardless of the dilution tested (p > .05). BCT had a lower percentage of viability than that of the control at all tested dilutions (p < .0001). Cell migration rates in BD and BCR were similar to those in the control group after 24 h and 48 h (p > .05), whilst BCT had larger voids than the control in both periods (p < .0001). Conclusions BCR, BCT and BD were associated with tooth discolouration. BCR had the lowest staining values, the highest radiopacity and viability greater than 80% hDPCs.

“…The most common method for color change evaluation was spectrophotometry, used in six studies [12,13,21,27,41,42], followed by spectrophotometry used with a digital camera [14,24,25,28,40], colorimetry [22], spectroradiometry [23], and only a digital camera [26].…”

“…Color changes were measured by calculating ∆E values in all studies. Eleven publications [12][13][14]21,22,[24][25][26]28,40,42] indicated human eye perceptible color change ranging from ∆E1.2 to ∆E3.7, whereas three articles [23,27,41] did not provide numeric information about ∆E thresholds, which were taken as perceptible to the human eye.…”

“…Biodentine has high biocompatibility and bioactivity, with enhanced properties, such as a quick setting time, homogeneity, perfect sealing ability, and high compressive strength [6,20]. In addition, it has been claimed that Biodentine causes less coronal discoloration than MTA [13,[21][22][23][24][25][26][27][28], as zirconium oxide did not result in discoloration, and, importantly, did not influence the hydration of the material [29,30]. Therefore, the lack of bismuth oxide in Biodentine significantly reduces the discoloration potential of the material [10,31].…”

Discoloration Potential of Biodentine: A Systematic Review

et al. 2021

View full text Add to dashboard Cite

The aim of this systematic review is to investigate the teeth discoloration potential of Biodentine. An electronic search in six databases (PubMed, Cochrane Library, LILACS, SCIELO, Web of Science, and Scopus) was conducted by three independent reviewers to identify eligible articles. The following search terms were used: ((discolo*, staining potential, color, colour, or spectrophotomet*), (teeth or tooth), and (Biodentine)). Methodology following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines was adopted for this investigation. At the end of the selection process, 30 articles were identified as eligible, of which 14 in vitro studies were included in this systematic review. Nine of the included studies evaluated the discoloration potential of Biodentine in the presence of blood. Within the limitations of this review, teeth discoloration using Biodentine is highly expected when material is placed in direct contact with blood during dental procedures. In the absence of blood, Biodentine causes less teeth color changes than MTA-based materials, but it is still unclear what clinically relevant results could be expected regarding the discoloration frequency and intensity induced by Biodentine.
