The main purposes of periodontal graft surgery include achieving root coverage, improving the clinical attachment level and keratinized tissue, and advancing the procedure of periodontal plastic surgery. Autogenous graft, such as subepithelial connective tissue graft-based procedure, provide the best outcomes for mean and complete root coverage, as well as increase in keratinized tissue. However, a disadvantage of the procedure is in the location of the operation itself: the additional surgical site (palate)...

Periodontal disease involves the activation of host immune response, acting not only as defender of periodontal tissues against bacterial aggression but also as mediator of tissue destruction. Triggering Receptor Expressed on Myeloid cells 1 (TREM-1) is an immune receptor that synergizes with Toll-like receptors in amplifying the inflammatory response mediated by microbial molecules. AIM: To investigate the role of P. gingivalis lipopolysaccharide (LPS) and the effect of LR12, a TREM-1 inhibitory peptide, on the expression of membrane-bound and soluble form of TREM-1 on human primary monocytes, as well as the production of pro-inflammatory cytokines...

Polymerase chain reaction (PCR) has become a popular diagnosis and research technique in dentistry. Several studies show that its high sensitivity and specificity allow it as a precise, efficient, and rapid method for detection, identification, and quantification of microorganism. Several genetic polymorphisms can be determined along with detection of immune and inflammatory markers, therefore providing the more accurate perception into the mechanisms underlying the dental and periodontal disease. This review paper discusses the application of PCR as a diagnostic technique in periodontology, endodontic infections, implant-related, and peri-implantitis infection, immune and inflammatory markers identification and genetic polymorphism as well as application of next generation sequencing and gene microarray technology in dentistry mentioned...

The European Society of Endodontology and the American Association for Endodontists have released position statements and clinical considerations for regenerative endodontics. There is increasing literature on this field since the initial reports of Iwaya et al. (2001) and Banchs & Trope (2004). Endogenous stem cells from an induced periapical bleeding and scaffolds using blood clot, platelet rich plasma or platelet rich fibrin have been utilized in regenerative endodontics. This approach has been described as a 'paradigm shift" and considered the first treatment option for immature teeth with pulp necrosis...

Mesenchymal stem cells (MSCs) are a promising therapeutic option for cell-based therapy due to their immunomodulatory and regenerative properties. They can be isolated from various adult tissues, including bone marrow, fat, dental tissue, and glandular tissue. Although they share common characteristics, little is known about the biological differences between MSC populations derived from different tissues. In this study, we used MS to compare the endogenous metabolite level in the human MSCs originating from the bone marrow, adipose tissue, periodontal ligaments, and salivary glands...
