Complicated crown fractures are emergency situations in dentistry that are frequently encountered in anterior teeth after trauma, especially in childhood, and result in pulp exposure. Pulp-preserving treatments are crucial for the long-term prognosis of the tooth. This case report describes the treatment process of an 8-year-old patient with a complicated crown fracture who underwent pulpotomy with mineral trioxide aggregate (MTA) and fracture fragment reattachment. An eight-year-old, systemically healthy girl presented to our clinic with a traumatic fracture of her maxillary right permanent central incisor. Clinical and radiographic evaluation revealed a complicated crown fracture and an open apex. A partial pulpotomy was performed using MTA to preserve the pulp. The fracture fragment, brought to our clinic 24 hours later in milk, was successfully fixed with composite resin following the pulpotomy. At 6 months of follow-up, no clinical or radiological symptoms developed, and the vitality of the involved tooth was preserved and its development continued. Partial pulpotomy using MTA is an effective and biocompatible option for vital pulp treatment in permanent teeth with open apexes. The reattachment technique increases patient satisfaction in terms of aesthetics and functionality and offers a minimally invasive approach. This case report demonstrates that complicated crown fractures can be successfully treated with conservative methods.

Objective: This study aimed to describe the CBCT-based positional measurements and morphological distribution of the mandibular foramen in growing individuals and to compare the M1, M2, and M3 measurements according to chronological age group, sex, and sagittal skeletal class. Materials and Methods: This retrospective cross-sectional study included 120 CBCT images of individuals aged 6–16 years (mean 10.31 ± 2.33 years; 67 male, 53 female) selected from 750 archived scans. Participants were divided into three age groups (6–8, 9–12, and 13–16 years) and classified using the ANB angle (Class I, II, and III). Three measurements were assessed: M1 (foramen to occlusal plane), M2 (to posterior ramus border), and M3 (to anterior ramus border). Foramen morphology was classified into five types: circular-, elliptical-, triangular-, rectangular-, and parallelogram-shaped. The Mann–Whitney U and Kruskal–Wallis tests were used, followed by Bonferroni-adjusted pairwise comparisons where appropriate. Results: Interobserver ICC values ranged from 0.75 to 0.81, indicating good interobserver reliability. In the unadjusted comparisons, no statistically significant differences in M1, M2, or M3 were detected according to sex or sagittal skeletal class (all p > 0.05). Significant age-related differences were identified in M2 between the 6–8 and 9–12 year groups (right p = 0.003; left p = 0.021) and between the 6–8 and 13–16 year groups (right p < 0.001; left p = 0.003). Elliptical morphology was most prevalent bilaterally (right 39.2%; left 40.0%). Conclusions: Statistically significant age-group differences were detected only for M2, whereas no statistically significant differences according to sex or sagittal skeletal class were detected in this sample. Greater M2 values in the older age groups represent a greater absolute linear distance between the fixed mandibular foramen reference point and the posterior ramal reference line and should not be interpreted as evidence of posterior displacement. Elliptical morphology was the most frequently observed form bilaterally. These findings provide anatomical information from clinically indicated CBCT examinations but do not support routine CBCT acquisition solely for mandibular foramen localization.

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.
