The Relationship Between Body Mass Index and Periodontitis

February 3, 2021 updated by: Mehtap Bilgin Çetin, Baskent University

The Relationship Between Body Mass Index and Stage/Grade of Periodontitis

This study aimed to examine the relationship between body mass index (BMI) and stage/grade of periodontitis per the current classification of periodontal diseases.

142 patients (82 males/60 females) were included in this study. "2017 World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions" was taken as basis to characterize the stage/grade of periodontitis. As well as age, gender, smoking status, and frequency of tooth brushing, medical data of the patients including hypertension, hyperlipidemia, BMI, and diabetes mellitus were obtained from the patient's hospital records. Obesity was assessed by BMI using the "World Health Organization" criteria.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

In this retrospective study, dental and medical records of 200 patients diagnosed with periodontitis who applied to Baskent University, Faculty of Dentistry, Department of Periodontology between January 2019 and January 2021 were reviewed. Fifty three patients were excluded due to unclear or missing data, and five subjects were not included as they were under the age of 18. The final study population therefore consisted of 142 patients (82 males/60 females).

As well as age, gender, smoking status, and frequency of tooth brushing, medical data of the patients including hypertension, hyperlipidemia, BMI, and diabetes mellitus were obtained from the patient's hospital records.

Periodontal records of the patients were obtained for six different sites (mesio-buccal, mid-buccal, disto-buccal, mesio-lingual, mid-lingual, and disto-lingual) per tooth.

Mean ± standard deviation (SD) and median (minimum-maximum) were utilized for quantitative variables, and number of patients (percentage) were utilized for qualitative variables as descriptors. For quantitative variables, Kruskal-Wallis H test was performed to see whether there was a statistically significant difference between categories of the qualitative variable with more than two categories. Chi-square test was used for investigating the relationship between two qualitative variables. For determining the risk factors considered to have an effect on the dependent quantitative variable, univariate and multivariate logistic regression analyses were performed. Statistical significance level was defined to be 0.05.

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

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Normal weight (<25 kg/m2)
Other: Measuring pocket depth
Probing pocket depth (PPD = distance between gingival margin and bottom of the periodontal pocket)were evaluated in each patient. All periodontal measurements were recorded at six sites around each tooth by a periodontal probe excluding third molar
overweight (25-29.9 kg/m2)
Other: Measuring pocket depth
Probing pocket depth (PPD = distance between gingival margin and bottom of the periodontal pocket)were evaluated in each patient. All periodontal measurements were recorded at six sites around each tooth by a periodontal probe excluding third molar
obese (≥30 kg/m2)
Other: Measuring pocket depth
Probing pocket depth (PPD = distance between gingival margin and bottom of the periodontal pocket)were evaluated in each patient. All periodontal measurements were recorded at six sites around each tooth by a periodontal probe excluding third molar

What is the study measuring?

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.

Study Major Dates

Study Start (ACTUAL)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 1, 2019

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
