Correlation Between Periodontitis and Hypertension Among a Sample of Adult Egyptian Patients: A Hospital-based Cross-Sectional Study

The study is a cross-sectional study investigating the correlation between periodontitis and both hypertension and body mass index among a sample of adult Egyptian dental patients attending diagnostic center at faculty of Dentistry, Cairo University.

Detailed Description

  • Dental patients will be recruited in a consecutive manner from the outpatient Diagnostic center, Faculty of Dentistry, Cairo University.
  • Before the interview, the aim of the study will be explained to the patient and the patient's acceptance to participate in the survey will be received.
  • Full questionnaire will be filled, then full mouth periodontal examination and charting will be done for each patient.
  • The questionnaire will be filled through a face-to-face personal interview with the patient using simple, short, easily comprehended questions (Goulart A.C., Armani F. et al. 2017, Machado V., Aguilera E. M. et al. 2020). The questionnaire will be translated by a certified translator into Arabic and validated. All the interviews will be done by the same investigator.
  • Non-respondent patients or patients refusing to participate will be reported with the cause of their refusal.
  • The questionnaire which will be applied in study will include sociodemographic and medical questionnaires. These covariates will include gender, age, marital status (single, married/union of fact, divorced or widowed), occupation (student, employed, unemployed or retired) and smoking habits (current status: never, former, current). Education will be categorized according to the 2011 International Standard Classification of Education (ISCED-2011) (UNESCO 2012): no education (ISCED 0 level), elementary (ISCED 1-2 levels), middle (ISCED 3-4 levels), higher (ISCED 5- 8 levels) (ISCED 2011). Blood pressure will be measured at the clinic by automated sphygmomanometer device. Finally, measurements of height and weight will be taken at the clinical exam and body mass index (BMI) will be calculated as kg/m2.
  • Clinical examination will be held on a dental unit using the light of the unit and a mirror. Periodontal status will be evaluated by full mouth charting using UNC 15 periodontal probe, including assessment of plaque index (PI), bleeding on probing (BOP), Probing Depth (PD), Clinical Attachment Level (CAL), gingival recession depth (Rec) and radiographic X-Ray imaging.
  • Periodontitis case is defined according to the latest available EFP/AAP consensus. It will be defined if interdental CAL is detectable at ≥ 2 non-adjacent teeth, or buccal or oral CAL ≥ 3 mm with PPD > 3 mm at ≥ 2 teeth. Periodontitis staging will be defined according to severity and extent. Concerning severity, interdental CAL at the site of the greatest loss of 1-2 mm, 3-4 and ≥5 was considered as mild (Stage 1), moderate (Stage 2), and severe (Stage 3 and Stage 4), respectively (Tonetti, Greenwell et al. 2018).

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Correlation between periodontitis and hypertension
Time Frame: Through study completion, an average of 1 year
  • Clinical examination will be held on a dental unit using the light of the unit and a mirror. Periodontal status will be evaluated by full mouth charting using UNC 15 periodontal probe, including assessment of plaque index (PI), bleeding on probing (BoP), Probing Depth (PD), Clinical Attachment Level (CAL) and digital radiographic imaging.
  • Periodontitis case is defined according to the latest available EFP/AAP consensus.
  • Blood pressure measured by using an automated sphygmomanometer device. hypertension will be defined as values of systolic blood pressure ≥ 140 mmHg or diastolic blood pressure ≥ 90 mmHg, or; the use of antihypertensive medication.
  • Then a questionnaire will be collected to estimate the prevalence of hypertension in periodontitis Egyptians adult patients.
Through study completion, an average of 1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Body mass index.
Time Frame: Through study completion, an average of 1 year
to estimate the impact of overweight and obesity in periodontitis cases by body mass index (BMI); which is calculated as the body weight (kg) divided by the square of the height (m).
Through study completion, an average of 1 year
