Obstetrics and Periodontal Therapy (OPT) Study (OPT)

July 24, 2015 updated by: University of Minnesota

Effects of Periodontal Therapy on Preterm Birth

The purpose of this study is to determine if non-surgical periodontal (gum) treatment can reduce the incidence of preterm birth and low birth weight babies in mothers with periodontitis (gum disease).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

Eight hundred sixteen women who are between 13 and 16 weeks pregnant will be enrolled in this trial. Volunteers will be recruited from Hennepin County Medical Center (MN), the Jackson Medical Mall (MS), the University of Kentucky, and Harlem (NY) Hospital. The incidence of preterm birth is higher at these sites than the national average. Subjects will be randomly assigned to receive non-surgical mechanical periodontal therapy (scaling and root planing) either prior to 20 weeks of their pregnancy or soon after delivery. All subjects will be monitored for progressive periodontitis and will be treated immediately regardless of their group assignment. All women will also receive essential dental care to restore caries and treat abscessed teeth. The primary birth outcome is gestational age at birth and the secondary outcome is birthweight. Maternal risk factors for preterm birth and/or intrauterine growth restriction will be used as covariates in the data analysis. The study will also document the effect of periodontal therapy on immune response, systemic markers of inflammation, periodontal infection and clinical periodontal measure.

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
823

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

16 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Description

Inclusion

  • Be pregnant in the first 13-16 weeks of gestation as determined by menstrual history and obstetrical ultrasound
  • Be at least 16 years of age
  • Have at least 20 natural teeth,
  • Have bleeding on probing (BOP) on at least 35% of all tooth sites
  • Have 4 or more teeth with pockets greater than or equal to 4 mm and attachment loss greater than or equal to 2 mm

Exclusion

  • Are unable to provide informed consent or are unable to cooperate with the study protocol.
  • May be placed at medical risk as a result of participation (i.e. subjects with hematologic disease or other disorders tha preclude routine non-surgical periodontal therapy).
  • Have multiple fetuses as diagnosed by ultrasound.
  • Require antibiotic prophylaxis for periodontal procedures
  • Require greater than 3 essential dental care visits because of extensive decay and/or broken teeth and are likely to have less than 20 natural teeth following essential dental care

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Active Comparator: Scaling and root planing
Scaling and root planing delivered prior to 21 weeks of gestation.
Procedure: Periodontal scaling and root planing
Hard and soft tisse deposits (plaque and calculus) are removed from the tooth and tooth root using hand and ultrasonic instruments.
Other Names:
  • Deep cleaning
Procedure: Scaling and root planing
Delivered using hand and powered scalers and with topical or local (injected) anesthetics as needed. Procedures performed over 1 to 4 90-minute visits.
No Intervention: Placebo
Delayed treatment group. Controls monitored clinically from baseline to 29-32 weeks of gestation. Scaling and root planing provided after delivery.

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.

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.
