Objective: To evaluate the effect of Yishenqinghuo recipe on biological characteristic of rat bone marrow stromal cells (BMSCs) and search for the function and mechanism of this recipe in treatment of periodontitis.
Methods: 12- to 15-month-old SD rats were allocated into 5 groups. Group A: control group (with no periodontitis model, fed with the same dosage of saline as Group D); Group B: model group (with periodontitis model, fed with the same dosage of saline as Group D); Group C: high dosage group (with periodontitis model, fed with a high dosage of medicine); Group D: middle dosage group (with periodontitis model, fed with a middle dosage of medicine); and Group E: low dosage group (with periodontitis model, fed with a low dosage of medicine). Ten days later, serums were collected from all the five groups for in vitro cultivation of BMSCs.
Results: There was displayed a similarity in effect between the serum collected from Group C1 (serum collected 0.5 h after the last gavage of Group C) and that from Group A after the last gavage, the effect being the best in terms of proliferation of BMSCs. A comparison with the other groups had revealed a striking difference (P < 0.01), with Group B having turned out to be the worst. The serum from Group C2 (serum collected 1 h after the last gavage of Group C) after the last gavage could best enhance the generation and activity of ALP, having demonstrated a significant difference (P < 0.01) in comparison with the other groups.
Conclusion: Yishenqinghuo recipe can improve the proliferation of BMSCs and facilitate the differentiation to osteoblast.

Department of Periodontology, Dental Student's Research Committee, Isfahan University of Medical Sciences, Isfahan, Iran.
Background: This systematic review and meta-analysis aimed to assess the efficacy of autologous platelet concentrate (APCs) in comparison with coronally-advanced flap alone or in combination with connective tissue graft or other biomaterials or bioactive agents for root coverage (RC) of Miller's Class I and II gingival recession defects by measuring the keratinized mucosa width (KMW).
Materials And Methods: This systematic review and meta-analysis was conducted in accordance with the preferred reporting items for systematic reviews and meta-analysis guidelines. An electronic search of the literature was conducted in PubMed, EMBASE, Scopus, Cochrane, Web of Science, Magiran, Scientific Information Database, and Irandoc for randomized clinical trials (RCTs) that used APCs for RC in their intervention group.

Objective: The aim was to compare the efficacy of local minocycline hydrochloride delivery (LMHD) and antimicrobial photodynamic therapy (aPDT) as adjuncts to mechanical debridement (MD) for the treatment of peri-implant mucositis (PM).
Methods: Patients with PM were included. The following information was retrieved from patients' digital dental records: (a) age, (b) gender, (c) duration of implants in function, (d) number of implants, (e) depth of implant placement, and (f) mode of prosthesis retention.
Risk factors for metabolic syndrome in the premetabolic state assessed using hierarchical clustering study in a health screening group.

Early detection of a premetabolic status that is at risk for metabolic syndrome (MetS) but not meeting the criteria is crucial. This study examined 27,623 participants aged 20-50 (mean: 40.7) years who underwent initial health screening at Kangbuk Samsung Hospital (2011-2019), focusing on individuals with one or two MetS components.

Unlabelled: Peri-implantitis (PI) is an inflammatory disease that affects supportive tissues around dental implants, and its progression eventually leads to bone loss and implant failure. However, PI effects may be different based on the presence or absence of adjacent teeth.
Objective: To investigate the differences in bone loss and inflammation between implants placed adjacent to a tooth or edentulous area in a ligature-induced PI model.
Salivary features of periodontitis and gingivitis in type 2 diabetes mellitus.
Sci Rep

Center for Oral Health Research, College of Dentistry, University of Kentucky, Lexington, KY, USA.
Type 2 diabetes mellitus (T2DM) is associated with cellular abnormalities, tissue and organ dysfunctions, and periodontitis. This investigation examined the relationship between the oral microbiome and salivary biomarkers in T2DM patients with or without periodontitis. This cohort (35-80 years) included systemically healthy non-periodontitis (NP; n = 31), T2DM without periodontitis (DWoP; n = 32) and T2DM with periodontitis (DWP; n = 29).
