- Brief Summary
To assess the impact of scaling and root planing on systemic inflammation and serum bone resorption markers in pre-menopausal women with periodontitis
- Detailed Description
Periodontitis is a chronic multifactorial inflammatory disease associated with dysbiotic plaque biofilms and characterized by progressive destruction of the tooth supporting apparatus. Its primary features include the loss of periodontal tissue support, manifested through clinical attachment loss (CAL) and radiographically assessed alveolar bone loss, presence of periodontal pocketing and gingival bleeding.
Periodontitis is multifactorial inflammatory disease with numerous systemic or local risk factors playing a part in its clinical sequences. Periodontitis causes increased local inflammation as well as contributes to systemic inflammation with an increase in the levels of local and systemic inflammatory mediators including tumor necrosis factor alpha (TNF-α), interleukin-1 and interleukin-6 (IL-6).
Osteoporosis is a systemic skeletal disease characterized by low bone mass and microarchitectural deterioration of bone tissue, with a consequent increase bone fragility and susceptibility to fracture.
The development of osteoporosis occurs through spontaneous increase in pro-inflammatory and pro-osteoclastic cytokines such as , IL-6 and IL-1 β that activates receptor activator of nuclear factor-Kb ligand (RANKL) leading to an enhanced ability of osteoclasts to resorb bone.
The Studies on systemic influence of periodontitis have suggested that locally produced proinflammatory cytokines such as IL-1β , TNF-α and IL-6 may be released into circulation. Most studies shows that IL-6 and TNF-α is major cytokine responsible for resorption of bone in osteoporosis and increase of bone turnover markers. Periodontitis is chronic inflammatory disease characterized by destruction of tooth supporting tissues by virtue of the immunologic response to bacterial challenge originating from dental plaque. In Periodontitis, the increased released of proinflammatory cytokines such as TNF- α, IL-1β, and IL-6 in systemic circulation which causes increase in systemic bone loss through their osteoclastic activity. The systemic inflammation and rate of bone loss is measured by systemic inflammatory and bone resorption markers respectively.
Till date there is no conclusive interventional study done on impact of management of periodontitis on systemic inflammation and bone resorption markers(serum CTX) in pre-menopausal women with periodontitis .
METHODOLOGY The study will be conducted as follows This prospective interventional study will be conducted in the department of Periodontics and Oral Implantology, Post Graduate Institute of Dental Sciences (PGIDS), Rohtak.
Periodontitis patients will be recruited from the outpatient department of PGIDS, Rohtak.
Sample Size calculation:
Sample size was calculated using G power software using t test to compare difference between two matched (dependent) means . Total sample size was calculated as 19. A total of 24 patients will be recruited expecting a 25% dropout rate.
Periodontal parameters:
At baseline, periodontal parameters plaque index (PI), gingival index (GI), bleeding on probing (BOP), probing depth (PD), clinical attachment loss (CAL) will be assessed at six sites (disto-buccal, mid-buccal, mesio-buccal, mesio-lingual, mid-lingual and disto-lingual) per tooth excluding third molars. Periodontal examination would be performed at baseline and 8 weeks after scaling and root planing.
Periodontal therapy:
After recording periodontal parameters at baseline, oral hygiene instructions would be given and scaling and root planning would be done. Patient would be recalled at after 8 weeks of complete scaling and root planing.
Blood collection and serum analysis:
For assessing markers of systemic inflammation and bone resorption, serum samples will be collected from venipuncture in antecubital fossa at 8 hours and after an overnight fasting for all subjects at baseline in individuals meeting the inclusion criteria. Serum samples would again be analyzed for systemic markers at 8 weeks after scaling and root planing in individuals who have bleeding on probing (BOP) less than 10% of the total sites.
Parameters of systemic inflammation that would be assessed:
Interleukin-6 (IL-6) Total leukocyte count(TLC) Differential leukocyte count (DLC) Platelet count Neutrophil/lymphocyte ratio (N/L) mean platelet volume platelet distribution width
Systemic marker of bone resorption that would be analyzed:
Serum C-terminal telopeptide of type 1 collagen (s-CTX-1)
Anthropometric parameter that would be measured:
Body Mass Index (BMI) calculated as weight/height 2 (Kg/m2)
METHOD:
Pre-menopausal women having stage 2 or stage 3 periodontitis would be enrolled to participate in the study. Those who fulfill the inclusion criteria would be enrolled in the study clinical periodontal parameters(CAL,PD,and BOP) would be recorded and venous blood samples for measuring serum levels of IL-6, and serum CTX-1 would be collected. Scaling and root planing would be performed in all cases.
Patients would be re-evaluated after 8 weeks for recording all the periodontal parameters and systemic inflammation (IL-6 ) and systemic resorption marker (serum CTX-1 ).
