Article Abstract
The oral innate immune response may diminish with aging. In the present study, the aim was to examine human β-defensin (hBD) 1-3 and human neutrophil peptide (HNP)-1 levels in the saliva of an elderly population to establish the extent of periodontal disease and tooth loss. A total of 175 individuals aged ≥ 65 years were divided into five groups based on the number of teeth with a pocket depth ≥ 4 mm as follows: 17 pocket-free individuals (Control), 55 individuals having 1-6 pocket teeth (PerioA), 33 individuals having 7-13 pocket teeth (PerioB), 29 individuals having at least 14 pocket teeth (PerioC), and 41 edentulous individuals. Their salivary defensin levels were measured with ELISA kits. The salivary HNP-1 levels were significantly higher in the Perio groups (PerioB: < 0.001 and PerioC: < 0.001) in comparison to the Control. The associations between salivary HNP-1 levels and the number of pocket teeth remained significant after adjustments for age, gender, level of education, and number of teeth. The salivary HNP and hBD levels differed in terms of their correlation to the extent of periodontal disease and tooth loss in the elderly.

Background: Periodontitis, a chronic inflammatory disease of tooth-supporting tissues, shows significant associations with systemic conditions like type 2 diabetes mellitus (T2DM) and obesity. These metabolic disorders share chronic inflammatory pathways that may influence periodontal disease severity. This study investigated these relationships using advanced quantifiable metrics - periodontal epithelial surface area (PESA) and periodontal inflammatory surface area (PISA).

Endodontic-periodontal lesions (EPLs) complicated by cemental tears present a diagnostic and therapeutic challenge. This case report describes the successful management of a 66-year-old male patient with a mandibular second molar (#18) exhibiting an EPL complicated by a cemental tear. Clinical examination revealed a draining sinus tract, deep periodontal pockets, and radiographic evidence of a "J-shaped" lesion and a radiopaque cemental fragment.

To analyze the composition of the oral microbiome in periodontal pocket lesions and on the tongue dorsum of patients with -associated gastric disease. Patients diagnosed with gastric disease and (HP+) were evaluated in comparison to a control group of -negative patients without gastric disease (HP-). Periodontal and oral health clinical parameters (PPD, BoP, PSE, plaque score and modified DMFT) were assessed for each patient.

Background/aim: A potential link between periodontitis and the development of gastric cancer (GC) has been reported. However, its prevalence and impact on patients with GC remain unclear. This study investigated the association between periodontitis severity and clinical parameters, including () infection and endoscopic findings, in patients with GC undergoing gastrectomy.

Background: The aim of this study was to investigate the clinical effect of Nd:YAG laser-assisted non-surgical periodontal treatment on patients with stage II/III periodontitis.
Methods: A total of 599 teeth from 22 patients with stage II/III periodontitis were included in this study. A split-mouth design randomly assigned one side to the laser group (subgingival instrumentation + Nd:YAG laser) and the other to the control group (subgingival instrumentation alone).
