Aim: The aim of this study is to evaluate the effect of restorative crown materials with different elastic moduli on stress distribution in dentin and supporting tissues of pulpotomized primary anterior teeth under multi-directional loading conditions using the three-dimensional finite element analysis method. Materials and Methods: A three-dimensional model of a maxillary primary central incisor was created based on anatomical data. A clinical pulpotomy scenario was simulated using mineral trioxide aggregate (MTA) and resin-modified glass ionomer cement. Three models were analyzed: healthy tooth (control), Bioflx crown, and prefabricated zirconia crown. Frontal, oblique, and vertical loads were applied to represent functional and traumatic conditions. von Mises and principal stress distributions in the crown, dentin, and supporting tissues were evaluated. Results: In the prefabricated zirconia crown group, higher von Mises stress values were observed under all loading conditions, with significant stress concentrations particularly in the cervical region. In contrast, the Bioflx crown group exhibited lower stress values and a more homogeneous stress distribution. While the stress patterns in the Bioflx group were found to be closer to those of the control group, more localized stress accumulation was observed in the zirconia crowns. No significant differences were observed between the groups in the bone tissue. Conclusions: The elastic modulus of restorative materials plays a decisive role in the stress transfer mechanism. It is believed that materials with dentin-like mechanical properties may provide a more balanced and physiological stress distribution. Multi-directional loading analysis highlights the importance of evaluating the biomechanical behavior of restorative materials under more realistic conditions. Further advanced experimental and clinical studies are needed to clinically validate these findings.

Traumatic dental injuries are most commonly seen in maxillary incisors. In trauma cases, healthy chewing, good aesthetic appearance and continuity of the tooth in the mouth to fulfil its functions in speech are desired. A mixed dentition male patient with a chronological age of 9 years and 1 month was admitted to Harran University Faculty of Dentistry due to a crown fracture in tooth number 11 caused by trauma. Intraoral examination revealed a complicated crown-root fracture in the tooth. Endodontic and restorative treatment of the tooth was planned. However, it was understood that there were not enough crowns for these procedures. Extrusion of the central tooth was planned. Bonding was performed between the first molars and teeth 12-22. Extrusion was started 3 months after the trauma. Activation was ensured with monthly controls. At 3 months, sufficient extrusion was achieved. Composite laminated restoration was successfully completed with increasing crown length. An ideal treatment result was achieved with a multidisciplinary approach in a 9-year-old child with crown-root fracture due to trauma.

Background/Objectives: This in vitro study compared the color stability of four pediatric restorative materials after exposure to three pediatric liquid medications in a 4 × 3 factorial design. Methods: Sixty disc specimens (10.0 × 2.0 mm) were prepared from a composite resin (Charisma Smart), a compomer (Nova Compomer), a giomer (Beautifil Kids SA), and a high-viscosity glass ionomer cement (HVGIC; Equia Forte HT with Equia Forte Coat) (n = 15 per material) and allocated to antibiotic, multivitamin syrup, and iron preparation subgroups (n = 5); the specimens were immersed for 2 min twice daily for 7 days. ΔE₀₀ values were calculated from VITA Easyshade V measurements at baseline and after exposure and were analyzed using two-way ANOVA with Bonferroni-adjusted comparisons. Results: Restorative material (F(3,48) = 11.221, p < 0.001) and medication type (F(2,48) = 6.937, p = 0.002) had significant main effects, whereas their interaction was not significant (F(6,48) = 1.676, p = 0.147). HVGIC showed significantly greater color change than the other materials (p < 0.05). Exposure to the antibiotic suspension was associated with greater discoloration than exposure to the iron preparation (p = 0.002). The giomer had the lowest mean ΔE₀₀, but it did not differ significantly from the compomer and composite resin. Conclusions: ΔE₀₀ differed significantly among the restorative products and among the three medication exposure conditions, with no significant interaction. Because no unexposed control group was included, these differences reflect comparisons between exposure conditions rather than the effect of the medications alone. These in vitro findings are product-specific and require clinical confirmation.
