Bone regeneration using activin A/BMP2 chimera (AB204) with collagen membrane in rats with calvarial defects
Yum H, Han HS, Lee JT, Cho YD and Kim S
Collagen has long been recognized as an excellent carrier for growth factors, and membrane-type collagen has been widely applied in dentistry for guided bone regeneration. This study was conducted to examine the effects of an activin A/BMP2 chimera (AB204) combined with a collagen membrane (CM) on bone repair in a rat calvarial defect model.

The aims of this study were 1) to investigate the effects of a subepithelial connective tissue graft (SCTG) and a volume-stable collagen matrix (VCMX) on soft-tissue volume gain in the immediate implant placement protocol, and 2) to determine whether polydeoxyribonucleotide (PDRN) can enhance the effects of a VCMX.
The activin/BMP-2 chimera AB204 promotes periodontal tissue regeneration in a buccal dehiscence model: a pilot study
Han HS, Lee JT, Cho YD and Kim S
A combination of activin and bone morphogenetic protein-2 (BMP-2), termed AB204, has been shown to improve osteogenic potential with fewer side effects than BMP-2 alone. This study was performed to evaluate the effect of AB204 on periodontal tissue regeneration in a dog buccal dehiscence model.

Immediate implant placement in the premolar maxillary area: a cone-beam computed tomography study
Najm A, Bihorac A, de Carvalho Machado V and Chrcanovic BR
This research aimed to investigate potential factors associated with the risk of perforation of the labial bone plate, nasal floor, or maxillary sinus floor during immediate implant placement (IIP) in the maxillary premolar area, utilizing a cone-beam computed tomography (CBCT) virtual study.
Highly accurate measurement of the relative abundance of oral pathogenic bacteria using colony-forming unit-based qPCR
Hwang J, Lee JH, Kim YJ, Hwang I, Kim YY, Kim HS and Park DY
Quantitative polymerase chain reaction (qPCR) has recently been employed to measure the number of bacterial cells by quantifying their DNA fragments. However, this method can yield inaccurate bacterial cell counts because the number of DNA fragments varies among different bacterial species. To resolve this issue, we developed a novel optimized qPCR method to quantify bacterial colony-forming units (CFUs), thereby ensuring a highly accurate count of bacterial cells.
Effect of anti-resorptive therapy on implant failure: a systematic review and meta-analysis
Jung J, Shim GJ, Park JS, Kwon YD and Ryu JI
This review was conducted to systematically assess the impact of bisphosphonates (BPs) and denosumab, used as anti-resorptive therapies, on the incidence of dental implant failure.
Clinical evaluation of implants placed within or beyond the boundaries of the alveolar ridge preservation: a retrospective case series with 10 weeks of observations in 28 patients
Ko YC, Koo KT, Li L, Lee D, Lee YM, Seol YJ, Kim TH and Lee J
This study investigated the effect of implant vertical positioning within alveolar ridge preservation (ARP) sites on implant stability quotient (ISQ) values, which were measured 10 weeks post-implantation.
Assessment of variations in the nasopalatine canal on CBCT: considerations from an anatomical point of view
Yadav U, Shenoy N, Ahmed J, Sujir N, M A and Gupta A
The nasopalatine canal (NPC) is one of the most significant anatomical markers in the anterior maxillary region. Its location is quite important, especially for implant placement. Therefore, the purpose of this study was to use cone-beam computed tomography (CBCT) to evaluate the morphology, size, and anatomic variations of the NPC.
Effects of cannabinoid receptor activation on lipopolysaccharide stimulation in human periodontal ligament stem cells
Leypold T, Herbsthofer A, Craveiro RB, Wolf M, Beier JP and Ruhl T
Periodontitis is an inflammatory disease that results in the loss of periodontal tissue. The endocannabinoid system has anti-inflammatory properties and displays considerable potential for tissue regeneration. In this study, we aimed to explore whether the activation of this system can alleviate or reverse the inflammatory phenotype of human periodontal ligament stem cells (hPDLSCs) induced by exposure to the inflammagen lipopolysaccharide (LPS).

Comparison of the biocompatibility and osteogenesis potential of whitlockite and an activin A/BMP2 chimera using a rat calvarial defect model: a pilot study
Lee JT and Kim S
The aim of this study was to evaluate bone regeneration using whitlockite (WH) nanoparticles, collagenated bovine bone mineral, and an activin A/BMP2 chimera (AB204) on calvarial defects in rats.
Saliva assay: a call for methodological standardization
Baek HJ, Kim KS, Kwoen M, Park ES, Lee HJ and Park KU
The oral cavity provides an ideal environment for microorganisms, including bacteria, viruses, and fungi, to flourish. Increasing attention has been focused on the connection between the oral microbiome and both oral and systemic diseases, spurring active research into the collection and analysis of specimens for healthcare purposes. Among the various methods for analyzing the oral microbiome, saliva analysis is especially prominent. Saliva samples, which can be collected non-invasively, provide information on the systemic health and oral microbiome composition of an individual. This review was performed to evaluate the current state of the relevant research through an examination of the literature and to suggest an appropriate assay method for investigating the oral microbiome. We analyzed articles published in English in SCI(E) journals after January 1, 2000, ultimately selecting 53 articles for review. Articles were identified through keyword searches in the PubMed, Embase, Cochrane, Web of Science, and CINAHL databases. Three experienced researchers conducted full-text assessments following title and abstract screening to select appropriate papers. Subsequently, they organized and analyzed the desired data. Our review revealed that most studies utilized unstimulated saliva samples for oral microbiome analysis. Of the 53 studies examined, 29 identified relationships between the oral microbiome and various diseases, such as oral disease, Behçet disease, cancer, and oral lichen planus. However, the studies employed diverse methods of collection and analysis, which compromised the reliability and accuracy of the findings. To address the limitations caused by methodological inconsistencies, a standardized saliva assay should be established.

Early wound healing at 1 week postoperatively in periodontal tissue regeneration therapy: enamel matrix derivative versus recombinant human fibroblast growth factor
Nakayama Y, Ogihara-Takeda M, Saito Y, Yamaguchi A and Ogata Y
Recombinant human fibroblast growth factor-2 (rhFGF-2) has demonstrated positive effects on wound healing at 2 weeks after periodontal surgery relative to enamel matrix derivative (EMD). However, the effects at earlier postoperative stages have not been reported. This retrospective study compared the early wound healing outcomes 1 week after surgery using the modified papilla preservation technique (mPPT) with either EMD or rhFGF-2 therapy.
