Saliva stands out as an advantageous diagnostic fluid due to various reasons that make it a reliable and practical source for analysis. Its abundance facilitates easy and large-scale sample collection, enhancing its diagnostic utility. The simplicity of collecting and storing saliva samples, combined with its accessibility and cost-effectiveness compared to other body fluids, makes it an attractive choice for diagnostic purposes. This study aims to investigate and compare variations in salivary biomarkers with their serum counterparts in specific oral diseases such as recurrent aphthous stomatitis (RAS), lichen planus (LP), and oral cancer (OC). A case-control study was conducted in 55 individuals, including 15 patients with RAS, 13 patients with LP, 12 patients with OC, and a 15 individuals in the control group. Saliva and serum samples were collected after a specified fasting period, and various biomarker analyses immunoglobulin A (IgA), cortisol, lactate dehydrogenase (LDH) were conducted using laboratory techniques. In this study, an independent samples t-test was employed to investigate the significant differences between the experimental groups and the control group. The results indicated that there was a statistically significant difference in the salivary IgA levels, salivary cortisol levels, and salivary LDH levels (P = .000) (P = .016) (P = .001), respectively, as compared to the control group. However, no significant differences were observed in serum cortisol levels (P = .363) and serum IgA levels (P = .101) when compared to the control group. Interestingly, significant differences materialized when evaluating serum LDH levels (P = .048) in the OC group as compared to the control group. Overall, this research contributes to a deeper understanding of the utility of salivary biomarkers in diagnosing oral diseases and may pave the way for improved diagnostic and treatment strategies in the field of oral health.

Purpose: The aim of this study was to investigate and compare the survival rate and the success rate of single tooth implants placed and restored immediately after extraction in non-infected, acutely infected, and chronically infected sites in the maxillary anterior area.
Material And Methods: Patients requiring single tooth replacement of a maxillary central incisor, lateral incisor, canine, and premolar regions were included in the study. Implant sites were divided into three groups based on the presence or absence of an infection: Group 1 (Control) non-infected sites (healthy periodontal and endodontic conditions); Group 2 (Test 1) acutely infected sites (presence of a periodontal or endodontic or combined abscess and/or fistula); Group 3 (Test 2) chronically infected sites ( presence of a periodontal pocket or a periapical lesion with no signs of acute inflamation).
Impact of Vitamin D3 on Postorthodontic Treatment Stability: A Randomized Controlled Trial.
J Contemp Dent Pract
December 2024
University of Minnesota School of Dentistry, Minneapolis, United States of America.
Aim: This study aims to clinically evaluate whether the local administration of vitamin D3 enhances postorthodontic tooth stability over a period of 3 months immediately after debonding.
Materials And Methods: Patients aged 15-30 years with dental malocclusion and moderate crowding in the lower arch (Little's irregularity score of 4-6) were selected and randomly split into the experimental and the control groups. After complete alignment and leveling, vitamin D3 injection was delivered to the experimental group and the control group was given a placebo injection with 0.
Effect of Open Flap Debridement with and without LLLT in Patients with Periodontitis on Wound Healing, GCF ALP Levels, and Clinical Parameters.
J Contemp Dent Pract
December 2024
Department of Periodontics, ITS Dental College, Hospital & Research Centre, Greater Noida, Uttar Pradesh, India.
Aim: The tenet of the study is to evaluate the efficacy of low-level laser therapy (LLLT) as an adjunct to surgical periodontal therapy [open flap debridement (OFD)] on clinical parameters, gingival crevicular fluid (GCF) alkaline phosphatase (ALP) levels in GCF and wound healing.
Materials And Methods: Thirty subjects afflicted with chronic periodontitis showing evidence of horizontal bone loss on the radiograph, pocket probing depth (PPD) between 4 and 7 mm, and ≥20 natural teeth present in the oral cavity were included in the study. In every patient, OFD+LLLT was done in one quadrant and OFD in another was performed.
