Article Synopsis
  • - The study examined the effects of diosgenin (DG), a steroidal saponin, on alveolar bone loss in rats with induced periodontitis using imaging and tissue analysis methods.
  • - Rats were divided into four groups, with two receiving different doses of DG over 29 days, and findings showed that as DG dosage increased, it effectively reduced periodontal damage and improved bone formation markers.
  • - Results indicated that DG not only lowered the expression of detrimental proteins related to bone loss but also significantly decreased alveolar bone loss compared to the periodontitis group, suggesting its potential as a treatment for periodontal issues.

Background: The aim of this study is to compare the effects of %4 articaine and %2 lidocaine on inferior alveolar nerve block (IANB) for implant surgery in the posterior mandible.

Material And Methods: The patients who have inserted implants in the posterior mandible were divided into 2 groups for IANB: lidocaine and articaine. VAS = visual analog scale, pain during surgery and injection, lip numbness time, mandibular canal-implant apex distance, age, gender, bone density, implant number, release incision, adjacent teeth, and duration of surgery were analyzed using t-test, Mann-Whitney U test, Spearman's coefficient, and, Pearson's chi-squared test.

Article Synopsis
  • This study investigates the effects of topical treatments (hyaluronic acid, hypochlorous acid, and flurbiprofen) on healing after free gingival graft surgery in 60 patients.
  • Patients were divided into four groups and monitored for 28 days, with healing assessed using various methods, including pain levels and tissue healing metrics.
  • Results showed that hyaluronic acid significantly improved healing compared to the others, with less pain and faster epithelization, while hypochlorous acid and flurbiprofen were less effective in promoting wound healing.

A series of 4,4'-diimine/4,4'-diazobiphenyl derivatives were designed, synthesized, and evaluated for their ability to inhibit both the acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) enzymes, as well as Aβ aggregation, in vitro. The AChE and BChE inhibition assays demonstrated that all compounds displayed moderate AChE inhibitory activity in the range of IC  = 5.77-16.

Background: IL-13 is the key cytokine in the regulation of inflammatory with an autoimmune disease and has an anti-inflammatory effect.

Aims: This study aimed to compare IL-13 (-1112 C/T and -1512 A/C) gene polymorphisms in patients with aggressive periodontitis (AgP), chronic periodontitis (CP), and periodontally healthy group (C) and evaluate the effect of nonsurgical periodontal therapy on gingival crevicular fluid (GCF) IL-13 levels in patients.

Materials And Methods: One hundred thirty patients with AgP, 120 patients with CP, and 70 periodontally healthy subjects were included in this study.

Background: The extraction of impacted third molar teeth is a common procedure in maxillofacial surgery. The aim of this study was to compare of piezoelectric surgical technique with the one with conventional rotary instruments in terms of edema, trismus and pain, in mandibular third molar surgery.

Material And Methods: 20 individuals with symmetrically impacted lower mandibular third molars and 40 teeth were included in the study.

This study indicates the synthesis, cholinesterase (ChE) inhibitory activity, and molecular modeling studies of 48 compounds as o- and p-(3-substitutedethoxyphenyl)-1H-benzimidazole derivatives. According to the ChE inhibitor activity results, generally, para series are more active against acetylcholinesterase (AChE) whereas ortho series are more active against butyrylcholinesterase (BuChE). The most active compounds against AChE and BuChE are compounds A12 and B14 with IC values of 0.

A series of Mannich bases of benzimidazole derivatives having a phenolic group were designed to assess their anticholinesterase and antioxidant activities. The acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) inhibitory activities were evaluated in vitro by using Ellman's method. According to the activity results, all of the compounds exhibited moderate to good AChE inhibitory activity (except for 2a), with IC values ranging from 0.

Introduction: Periodontitis is a chronic inflammatory and osteolytic disease. Vitamin B complex is a class of water-soluble vitamins that play important roles in cell metabolism.

Objective: The aim of this study was to evaluate the effects of riboflavin (RBF), nicotinamide (NA), and folic acid (FA) on alveolar bone loss in experimental periodontitis rat model.

Background: Bone healing is impaired in diabetes mellitus (DM) cases. The aim of this study is to investigate, both morphometrically and immunohistochemically, the effect of gaseous ozone on bone healing in diabetic rat calvarial defects treated with xenografts.

Methods: DM was induced with 50 mg/kg intraperitoneal streptozotocin in 56 male Wistar rats.

A series of N-{2-[4-(1H-benzimidazole-2-yl)phenoxy]ethyl}substituted amine derivatives were designed to assess cholinesterase inhibitor activities. Acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) inhibitor activities were evaluated in vitro by using Ellman's method. It was discovered that most of the compounds displayed AChE and/or BuChE inhibitor activity and few compounds were selective against AChE/BuChE.

Benzimidazoles of both natural and synthetic sources are the key components of many bio-active compounds. Several reports have shown antifungal, antiviral, H(2) receptor blocker and antitumor activities for benzimidazoles and their derivatives. In this study, we synthesized twelve bis-benzimidazole derivatives by selecting di(1H-benzo[d]imidazol-2-yl)methane as the main compound.

Benzimidazole is one of the most important heterocyclic groups manifesting various biological properties, such as antibacterial, antifungal, antimicrobial, antiprotozoal and antihelmintic activities. Several benzimidazole derivatives are also active as inhibitors of type I DNA topoisomerases. In this study, three 1H-benzimidazole derivatives with different electronic characteristics at position 5-, namely 5-chloro-4-(1H-benzimidazole-2-yl)phenol (Cpd I), 5-methyl-4-(1H-benzimidazole-2-yl)phenol (Cpd II) and 4-(1H-benzimidazole-2-yl)phenol (Cpd III), were synthesized and evaluated for their effects on mammalian type I DNA topoisomerase activity using quantitative in vitro plasmid supercoil relaxation assays.

Covariance data are required to assess uncertainties in design parameters in several nuclear applications. The error estimation of calculated quantities relies on the nuclear data uncertainty information available in the basic nuclear data libraries, such as the US Evaluated Nuclear Data Library, ENDF/B. The uncertainty files in the ENDF/B library are obtained from the analysis of experimental data and are stored as variance and covariance data.
