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).
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 reponse, systemic markers of inflammation, periodontal infection and clinical periodontal measure.

This study is to determine whether scaling and root planing (SRP) followed by photodynamic disinfection results in improved outcomes that persist over time in adults with chronic periodont...
Periodontal disease (commonly called gum disease) is generally treated by deep cleaning of the root surfaces of the teeth. This is also called scaling and root planing. Placing a topical a...
This study is a prospective randomized open-label controlled study in which the Pocket-X Gel, a periodontal in-situ gelling product, or Pocket-X Chip, a periodontal film, will be applied t...
Dental bacterial plaque is the most frequent modifiable finding in patients with periodontal (gum) diseases. Many studies have provided evidence that mechanical removal of dental plaque is...

To assess the impact of scaling and root planing (SRP) with and without adjunct photodynamic therapy (PDT) in the treatment of periodontal disease (PD) in hyperglycemic patients.
Full-mouth scaling and root planing (FM-SRP) acts as a potent inflammatory stimulus immediately after treatment; however, systemic inflammation typically improves in the long term. The contribution of...
Our research aimed to detect the efficacy of non-surgical periodontal treatment with Nd: YAG laser and scaling and root planning (SRP) for chronic periodontitis.
In this study, we aimed to histologically and immunologically evaluate the effect of diode laser treatment when applied adjunctive to scaling and root planing (SRP) in an experimental periodontitis mo...
Recently, brain-derived neurotrophic factor (BDNF)/high molecular weight hyaluronic acid (HMW-HA) complex with flap surgery has been shown to promote periodontal tissue regeneration. The objective of ...
Removal or disruption of DENTAL DEPOSITS and plaque-retentive DENTAL CALCULUS from tooth surfaces and within the periodontal pocket space without deliberate removal of CEMENTUM as done in ROOT PLANING and often in DENTAL SCALING. The goal is to conserve dental cementum to help maintain or re-establish healthy periodontal environment and eliminate PERIODONTITIS by using light instrumentation strokes and nonsurgical techniques (e.g., ultrasonic, laser instruments).
A procedure for smoothing of the roughened root surface or cementum of a tooth after subgingival curettage or scaling, as part of periodontal therapy.
Inflammation and loss of connective tissues supporting or surrounding the teeth. This may involve any part of the PERIODONTIUM. Periodontitis is currently classified by disease progression (CHRONIC PERIODONTITIS; AGGRESSIVE PERIODONTITIS) instead of age of onset. (From 1999 International Workshop for a Classification of Periodontal Diseases and Conditions, American Academy of Periodontology)
Loss or destruction of periodontal tissue caused by periodontitis or other destructive periodontal diseases or by injury during instrumentation. Attachment refers to the periodontal ligament which attaches to the alveolar bone. It has been hypothesized that treatment of the underlying periodontal disease and the seeding of periodontal ligament cells enable the creating of new attachment.
Removal of degenerated and necrotic epithelium and underlying connective tissue of a periodontal pocket in an effort to convert a chronic ulcerated wound to an acute surgical wound, thereby insuring wound healing and attachment or epithelial adhesion, and shrinkage of the marginal gingiva. The term is sometimes used in connection with smoothing of a root surface or ROOT PLANING. (Jablonski; Illustrated Dictionary of Dentistry, 1982)
