“…A recent systematic review with meta‐analyses concluded that bovine teeth represent a suitable substitute for human teeth on bond strength assays of adhesive systems, producing similar results in enamel or dentine substrates (Soares et al . ). Nevertheless, it is still unknown whether testing the bond strength of root canal sealers using an intra‐tooth model of bovine teeth would produce similar results as compared to human dentine.…”

Aim To investigate the reliability of using bovine teeth as an alternative to human teeth in an intra‐tooth push‐out model by comparing the bond strength of three root canal sealers in both tooth substrates. Methodology From human and bovine incisors (12 per group), one 1‐mm disc was obtained from each root. On each disc, three standard 0.8‐mm‐diameter holes were drilled through the dentine. After irrigation, the holes were filled with one of three root canal sealers: AH Plus, MTA Fillapex or Total Fill BC Sealer. Tooth slices were kept in contact with sterile gauze moistened in PBS solution (pH = 7.2) for 7 days at 37 °C, and finally, a push‐out load was applied until sealer dislocation. The bonded interface area was calculated to obtain data in MPa. The push‐out data for each sealer and the overall push‐out data for human and bovine teeth were compared (Mann–Whitney U). Kruskal–Wallis was used to study the sealers behaviour at each of the dental substrates. Multiple comparisons were performed using Mann–Whitney U after Bonferroni correction (P < 0.05). Results Dentine substrate did not influence the push‐out of either individual sealers or overall sealers tested (Mann–Whitney U, P > 0.05). In both human and bovine samples, AH Plus performed better than BC Sealer and MTA Fillapex, whilst BC Sealer also provided a superior push‐out compared to MTA Fillapex (Mann–Whitney U, P < 0.05). Conclusion When using an intra‐tooth model, bovine teeth did not significantly influence the bond strength of sealers.

“…Recent papers reviewed the use of bovine teeth as a substitute for human teeth in dental research and confirmed that bovine dentin is widely used in dental research. Although bovine teeth can be a reliable substitute for bond strength studies to dentin [31], there were inconsistencies in the literature comparing human and bovine teeth and it was concluded that differences in morphology, chemical composition and physical properties between human and bovine dentin must be considered when interpreting results obtained when bovine teeth are used [32]. With regard to mechanical properties, no significant differences were reported between human and bovine dentin for fatigue, ultimate tensile strength and modulus of elasticity [33, 34].…”

ObjectiveTo determine the effects of whitening strips on bovine dentin fatigue resistance and flexural strength in vitro.Materials and methodsA total of eighty bovine dentin specimens (2x2x17mm) were treated with either: control glycerine gel on plastic film wrap or whitening strips containing 9.5% hydrogen peroxide. Treatment was applied for 30 minutes, twice a day, for 1- or 4-weeks. After the last treatment, ten specimens per group were randomly selected to undergo fatigue testing (106 cycles, 3Hz, 20N) while the other ten were subjected to flexural strength testing after ten days of storage in artificial saliva. Kaplan-Meier method with a log rank test, Wilcoxon test and Cox regression were used to assess fatigue test results (p<0.05). One-way ANOVA and Tukey’s tests were used to compare the flexural strength results (p<0.05).ResultsThere were significant differences in survival during the fatigue test among the groups (p<0.001). Treatment (control or bleach) was a significant factor for specimen survival (p<0.001, Exp(B) = 33.45). There were significant differences in mean flexural strength (p<0.001). No significant difference was found between “1-wk control” and “4-wk control”. The mean flexural strength and fatigue resistance of the “4-wk bleach” were significantly lower than all the other groups.ConclusionsThe use of whitening strips reduced the fatigue resistance and flexural strength of bovine dentin in vitro. Until the effect of whitening strips on mechanical properties of human dentin is fully elucidated, it remains prudent to advise patients to avoid excessive direct use of whitening strips on dentin.

ObjectivesUnderstanding human tooth structure fluorescence aids clinical and forensic dentistry, enabling tissue/material differentiation and the creation of esthetic restorative materials. Material manufacturers seek to replicate natural tooth fluorescence, necessitating the development of novel techniques to detect them. Procuring human teeth for research is challenging due to ethical and infection control standards, prompting a search for alternative models.Material and MethodsThis study compares visible light‐induced fluorescence of porcine and human teeth to assess the value of porcine teeth as human analogs. Using a pulsed laser, an optimal fluorescence‐inducing wavelength was determined, followed by comparing fluorescence spectra between species.ResultsLuminescence sensitivity and lifetimes were comparable between species, but spectral geometry differed.ConclusionPorcine teeth, commonly used for dental material investigations, may not be suitable for dental fluorescence studies due to spectral differences. Accurately mimicking human tooth fluorescence remains complex. Further research is needed to develop reliable alternatives for dental fluorescence investigations that will advance clinical and forensic dentistry.
