This study reports a case of complicated crown-root fractures of the maxillary central incisors (teeth 8 and 9) in a 10-year-old boy. Vital pulpotomy and iRoot BP Plus capping were performed to protect the pulp. The fractured crown fragments were used to restore the tooth morphology, and the esthetics and function of both central incisors were restored. The roots of the affected teeth continued to develop normally. Twenty-five months after the initial treatment, the patient suffered another trauma, resulting in a second dislodgement of the fractured crown of the left maxillary central incisor. Given the structural integrity of the fractured crown, reattachment was performed again to reshape the tooth, thereby restoring its appearance to the greatest extent possible. After a 40-month follow-up, the esthetics and function of teeth 8 and 9 remained satisfactory. Normal anterior occlusion was established, and the treatment outcome was highly appreciated by the patient and his parents. This case provides clinical detail useful for managing complex crown and root fractures caused by multiple traumas in young permanent teeth, emphasizing the importance of pulp preservation, conservative restoration, and preventive measures.

Developmental enamel defects can negatively affect esthetics and patient satisfaction. Minimally invasive treatments have emerged as alternatives to conventional restorations, but quantitative evaluation of their outcomes is limited. The objective of this case report was to assess the efficacy of a combined minimally invasive approach in improving enamel appearance using objective color and fluorescence measurements. A 23-year-old male patient presented with enamel hypoplasia and opacities on 24 teeth. The treatment protocol included: (1) three weeks of at-home bleaching with 16% carbamide peroxide using a custom tray; (2) micro-abrasion with 6.6% hydrochloric acid and silicon carbide slurry followed by 5% sodium fluoride varnish; and (3) applications of 15% hydrochloric acid etching, drying, and resin infiltration. The patient was advised to use a remineralization agent for one month. Fluorescence measurements and color contact-spectrophotometer readings were recorded at baseline, after each treatment stage, and during six- and 12-month follow-ups. Marked improvements in enamel color and fluorescence were observed after bleaching and resin infiltration, and despite a slight decline over time, values remained superior to initial measurements during follow-ups. This multistage minimally invasive approach achieved substantial improvements in enamel appearance, demonstrating its effectiveness for managing enamel opacities.

This report from the Research Committee of the Academy of Operative Dentistry brings together the most important research and clinical progress from 2024 to 2025. The review presents an evidence-based assessment of current advancements in research methodology, cariology, adhesion, materials science, and digital technologies. Methodological enhancements concentrate on the application of standardized reporting frameworks, including SPIRIT/CONSORT-Outcomes 2022 and CRIME-Q, to enhance the reproducibility and clinical applicability of restorative trials. In cariology, the biological paradigm shift underscores minimally invasive, risk-oriented management, with substantial evidence advocating for selective caries removal and vital pulp therapy to maintain pulpal vitality in permanent teeth. Materials research shows how resin composites have changed over time to include bioactive, universal-shade, and bulk-fill formulations that are meant to be efficient in the clinic and release therapeutic ions. The addition of digital workflows, such as intraoral scanning, artificial intelligence (AI) to help with diagnosis, and objective spectrophotometric shade mapping, is also changing traditional restorative protocols. Additive manufacturing (3D printing) introduces new ways to fabricate ceramics, but subtractive milling is still superior for making high-load restorations. These findings collectively highlight a pivotal shift towards precision-oriented, biologically integrated restorative care aimed at enhancing long-term clinical outcomes.
