  Scientific journal, Anterior midline diastema is a common esthetic concern that can adversely affect smile appearance. Direct composite resin restoration has emerged as a conservative treatment option for diastemas associated with tooth size discrepancies, as it allows intraoperative adjustment of tooth morphology and shade. Digital dentistry has improved clinical outcomes by increasing workflow efficiency, enabling integration with other healthcare technologies, and supporting more accurate and predictable treatments. The objective of this case report was to describe the management of anterior midline diastema and spacing in the maxillary anterior region using a 3D‐printed matrix to achieve the intended esthetic outcome. An optical impression was acquired using an intraoral scanner. Because the occlusal relationship of the remaining dentition was stable, the maxillomandibular relationship was recorded using the same device. A maxillary incisal matrix was digitally designed using dental CAD software and fabricated with a 3D printer in a transparent photopolymerizable resin. After the matrix was positioned on the maxillary arch, a flowable composite resin was injected into the mold and subsequently light‐cured. Occlusal interferences were eliminated, and all restorations were finished and polished using polishing strips and a silicone point. Postoperative instructions were provided. The teeth were successfully reshaped in accordance with the digital design, achieving the planned esthetic and functional improvements. Direct composite restoration using a 3D‐printed matrix provides a rapid, convenient, and predictable approach for managing anterior midline diastema. This technique enables precise transfer of the digital design to the clinical setting, allowing improved control of morphology and symmetry. A 3D‐printed matrix can therefore be considered a reliable alternative to conventional freehand composite restoration for maxillary anterior esthetic rehabilitation, particularly in cases involving midline diastema and spacing.

  English, Scientific journal, Abstract
  Recently, premix bioceramic-based pulp capping (BPC) materials have been introduced with desirable properties. However, data regarding the bioactivity and biocompatibility of these materials remain limited. This present study aimed to evaluate the bioactivity and biocompatibility of BPC materials. This study consisted of five experimental groups: Bio C Repair (BCR); BG Multi (BGM); Well pulp ST (WPS); ProRoot MTA (PMTA); and a no capping (NC) group. Measurement of pH, calcium ion (Ca2+) release, and a bioactivity test were performed. An in vivo experiment was conducted on maxillary first molars of Wistar rats with exposed pulp, and pulpal responses were assessed at 1, 3, 7, and 28 days. Immunohistochemical expressions of Nestin, Osteopontin, and DMP-1 were performed. All materials exhibited alkaline pH. BCR exhibited the highest Ca2+ release (p < 0.05). PMTA, BCR, and WPS produced well-formed calcium phosphate depositions. On day 1, BCR, BGM and NC groups showed no to mild inflammatory responses (p < 0.05). On day 3, mild to moderate inflammatory responses was observed in all groups except for the NC group. On day 7, BCR and WPS groups exhibited no to mild inflammatory responses, along with the mineralized tissue layer formation (MTF). On day 28, no inflammatory responses were observed in the BCR, BGM, and WPS groups. Complete and homogenous MTF was identified in all experimental groups except the NC groups. Variable expression of Nestin, Osteopontin, and DMP-1 was noted at different time points. This present study demonstrated that premix BPC materials exhibited favorable bioactivity and biocompatibility and may serve as potential substitutes for PMTA.
