Background/purpose: Identifying crestal bone level (CBL) on the buccal and lingual aspects poses challenges in conventional dental radiographs. Given that optical coherence tomography (OCT) has the capability to non-invasively provide in-depth information about the periodontium, this in vitro study aimed to assess whether OCT can effectively identify periodontal landmarks and measure CBL in the presence of gingiva.
Materials And Methods: An in-house handheld scanning probe connected to a 1310-nm swept-source OCT (SS-OCT) system, along with self-developed algorithms were employed to measure the CBL in dental models with artificial gingiva.

Background/purpose: Revascularization procedures are used over apexification to treat teeth with necrotic pulp tissues and incomplete root formation. Clinically, inducing proliferation, migration, matrix deposition, and differentiation of stem cells from apical papilla (SCAPs) are critical for pulp regeneration. The study aimed to elucidate the impact of bone morphogenetic protein-4 (BMP-4) on plasminogen activation molecules and the osteogenic/odontogenic differentiation of SCAPs, as well as understand the related signaling mechanisms.

Background/purpose: Dental implants can restore both function and aesthetics in edentulous areas. However, the absence of cushioning mechanical behavior in implants may limit their clinical performance and reduce the long-term survival rates. This study aimed to establish an implant cushion mechanism that mimicked the natural periodontal ligament, utilizing the properties of composite hydrogels.

Background/purpose: This study assessed the ability of experimental materials consisting of dicalcium silicate (DCS) and tricalcium silicate (TCS) with nanosized particles to form intratubular crystals under phosphate-buffered saline (PBS) and the effect on dentin permeability reduction.
Materials And Methods: By isolating the cervical part of the extracted premolars, 195 specimens were obtained. Two experimental materials (DCS/TCS and TCS) were applied to the dentin surface by brushing and stored in PBS (n = 65).

Background/purpose: Salivary microbiome has become a surrogate indicator of oral disease due to its collective reservoirs and convenience in sampling. However, failed clinical trials often lead to wastes of resources, indicating a need for preclinical models. In this pilot study, we aimed to compare the salivary microbiome by metagenomics analysis before and after lysogeny broth culture for prospective translational studies.

Background/purpose: Orthodontic movement is often necessary for periodontally compromised patients to enhance esthetics, function, and long-term occlusal stability. However, the impact of orthodontic treatment immediately following the regeneration of intrabony defects on periodontal healing remains a topic of debate. The objective of this long-term case series study was to test the hypothesis that orthodontic treatment performed immediately after regenerative procedures for periodontal intrabony defects did not adversely affect periodontal healing.
