Periodontitis and Adverse Pregnancy Outcomes in Metabolic Syndrome Patients- Interventional Study
Association Between Periodontitis and Adverse Pregnancy Outcomes in Metabolic Syndrome Patients- Interventional Study
Aim The Aim of the current study is to establish the association between periodontitis and adverse pregnancy outcomes in metabolic syndrome (Mets) patients and to evaluate the effect of intervention.
Objectives
- To evaluate the changes in periodontal status of pregnant women with metabolic syndrome after non surgical periodontal therapy (NSPT)
- To evaluate the inflammatory marker levels in serum of pregnant women with metabolic syndrome after non surgical periodontal therapy
- To evaluate the effect of NSPT on adverse pregnancy outcomes of women with metabolic syndrome

Подробное описание
Research Design/Methodology Ethics approval will be obtained from Institution Review Board of Riyadh Colleges of Dentistry and Pharmacy.
Sample size calculation (Green, 1991) By considering the Green's formula as below; Medium effect size (R2=0.07) variance in dependent variable accounted for by the independent variable. Beta weights of (ß=0.20). N≥104+k (Number of independent variable) .Hence total sample size required by considering 8 independent variables will be N=104+8=112. Expecting a patient drop out rate of 30%, the sample size is being increased to 50 patients per group. Approximately 150 patients will be recruited from maternity hospitals of Riyadh City.
Written informed consent will be obtained from patients after explaining the details of the study. Patients will be evaluated using a detailed questionnaire. Demographic characteristics such as age, diet, medical history etc will be recorded. All participants will be interviewed by principal investigator at each visit to capture oral hygiene knowledge and behaviors and exposure to risk factors for adverse pregnancy outcomes. Reviews of medical records will be conducted by principal investigator to record pregnancy history, document the course of the current pregnancy, and record any adverse events. All patients will be advised to report immediately to our dental clinic in case they have any dental related issues during the study period.
Examination Procedure All dental examinations will be performed by principal investigator. Clinical oral examinations will record number of teeth, the number of filled and carious teeth.
Outcome Measures: Periodontal parameters: Gingival Index, Plaque Index, Bleeding on probing, Probing depth (PD), Clinical attachment loss (CAL)
A complete periodontal examination will be conducted with the following assessments:
Bleeding on probing, Probing depth and clinical attachment level will be evaluated at six sites per tooth, whereas plaque index and gingival index will be evaluated at four sites per tooth.
Gingival index (GI). All teeth except third molars will be evaluated for gingival inflammation using a modification of the Loe and Silness , 1963 GI. The GI uses the following scores: 0 = normal gingiva; 1 = mild inflammation; 2 = moderate inflammation; and 3 = severe inflammation.
Plaque index (PI). Prebrushing plaque scores for the buccal surface of each tooth will be assigned using a zero to three scale (Silness and Loe, 1964 ) PI, with ''0''indicating an absence of plaque on the clinical crown and a ''3'' indicating the presence of soft deposits covering more than two-thirds of the crown.
Bleeding on probing (BOP). BOP will be assessed during and recorded after probing measures will be taken for each quadrant. The scoring will be as follows:
0 = absence of bleeding; 1 = bleeding present.
Probing depth. and gingival recession .A manual periodontal probe University of North Carolina -15 probe (UNC-15) , Hu-Friedy, Chicago, Illinois ,will be used to record on all teeth present in the mouth.
Probing depth will be calculated from gingival margin to base of pocket. CAL will be calculated using the clinically detectable cemento-enamel junction (CEJ) as reference and it will be measured from CEJ to base of pocket.
Case definition of Periodontitis outlined by Page & Eke (2007) will be used. The case definition for severe periodontitis requires two or more interproximal sites with CAL > 6 mm, not on the same tooth, and one or more interproximal sites with PD >5 mm. Moderate periodontitis is defined as two or more interproximal sites with CAL >4 mm, not on the same tooth, or two or more interproximal sites with PD >5 mm, not on the same tooth.
Adult Treatment Panel (ATP) III criteria for Mets will be met if an individual has three or more of the following components (Dos Prazeres Tavares et al, 2016):
Abdominal obesity: waist circumference >88 cm (35 inches) in women; Pregestation Body mass index (BMI) > 30kg/m2 High fasting glucose (FPG): serum glucose level > 110 mg/dl (6.1 mmol/l) or on treatment for diabetes; High blood pressure (BP): systolic BP >130 mm Hg and/or diastolic BP >85 mm Hg or on treatment for hypertension (HTN) Hypertriglyceridemia: serum triglyceride level >150 mg/dl (1.69 mmol/l); and Low high-density lipoprotein (HDL) cholesterol: Serum HDL cholesterol <50 mg/dl (1.29 mmol/l) in women.
Clinical data and samples of blood will be collected at three intervals
- At baseline (before 20 weeks gestation)
- 8 weeks after completion of periodontal therapy
- Within 1-2 days of delivery
Serum bio markers: Interleukin-6(IL-6), Prostaglandin-E2 (PG-E2)
Pregnancy Outcomes: Preterm birth < 37 weeks, Low birth weight < 2500 gms, Preterm low birth weight.
The patients and technicians who will perform the lab analyses will be blinded to group assignment.
Study Design It is a randomized clinical trial. Group 1- Case- Periodontitis patients undergoing Comprehensive periodontal treatment Group 2- Control- Periodontitis Patients undergoing single visit supragingival scaling Group 3- Placebo- Patients without Periodontitis undergoing single visit supragingival scaling After the collection of clinical data, the participants will be randomly allocated to either groups of the study using sealed opaque envelopes labeled with a study number and containing the group allocation. Allocations will be computer generated by a third person who will not otherwise be involved in the study. The Case group participants will receive non-surgical periodontal therapy that will be completed by the end of week 20-21 of gestation. This will consist of oral hygiene instruction with comprehensive periodontal treatment which will include excavation and sealing of cavities, removal of overhanging restorations, extraction of hopeless teeth followed by supragingival and subgingival scaling and root planing (SRP) of sites with PDs > 4 mm and polishing of all the teeth. Participants will be offered treatment under local anesthetic when necessary. No limits will be imposed on the number of dental visits needed to accomplish periodontal therapy.
The control and Placebo group participants will receive oral hygiene instruction and supragingival cleaning of all teeth at their baseline visit. Clinical periodontal related data will be collected at a subsequent review appointment 8 weeks after treatment for all groups.
All control participants will be offered the opportunity to attend for comprehensive periodontal therapy postpartum.
Blood samples will be collected after 10 hours of over night fasting. Serum triglyceride, Serum HDL cholesterol and serum glucose will be quantified using standard laboratory procedures in same medical laboratory for all samples collected.
A 5-ml sample of peripheral venous blood will be collected by vein puncture. The blood samples will be centrifuged at 3000 g for 5 min and the serum will be separated. The serum samples will be frozen in plastic vials at -20º Centigrade until further analyzing. Commercially available ELISA assays will be used to measure concentrations of IL-6, and PGE2 in blood samples, according to the manufacturer's recommendations.
Data analysis will be done using Statistical Package for the Social Sciences (SPSS) software. Mean and standard deviation for all clinical parameters. Differences between groups will be assessed using independent t-tests. Sample distribution according to demographic, socio-economic and behavioral data will be assessed using chi-square and Fisher_s exact tests. Between-group differences on the distribution of obstetric data will be assessed using Fisher_s exact test, and differences in adverse pregnancy outcomes will be compared using the independent t-test. Serum bio markers will be presented as median and 25% and 75% percentiles. Differences between groups will be assessed using the Mann- Whitney U-test, and differences among experimental periods will be assessed using the Wilcoxon signed-rank test. The Holm-Bonferroni method will be used to adjust for multiple comparisons. Statistical significance will be set at 5%
