Oral Infections and Pregnancy: Knowledge of Gynecologists/Obstetricians, Midwives and Dentists.

Purpose: To establish an inventory of knowledge, attitudes and daily pratice of dental and medical practitioners in France regarding oral health care and its relationship to pregnancy, particularly to preterm delivery and low birth-weight infants.

Materials And Methods: A questionnaire was distributed to health-care professionals (n= 460), consisting of 100 prenatal care practitioners (obstetricians, midwives) and 360 dentists, about their knowledge of oral alterations during pregnancy, the possible association between periodontal disorders and preterm/low birth weight, and their conduct toward their patients.

Results: Bleeding gums and pregnancy gingivitis were the oral manifestations most often cited by all the practitioners.

[Dental care during pregnancy].

Aim: to understand and analyze knowledge and practices of dentists regarding dental care during pregnancy using a questionnaire which focuses on the knowledge of the relationship between oral infections and complications of pregnancy, the attitude of practitioners on the implementation of dental care during pregnancy and the training of practitioners.

Results: 53.9% of pregnant women are not referred by an obstetrician.

Clinical outcomes after nonsurgical periodontal therapy with an Er:YAG laser device: a randomized controlled pilot study.

Objective: The purpose of this study was to compare the short-term effects of nonsurgical periodontal treatment with the short-term effects of Er:YAG laser debridement (ERL) and manual scaling and root planning (SRP) in nonsmoking patients with chronic periodontitis.

Methods: Nineteen nonsmoking patients (mean age 60.7) with chronic generalized periodontitis were randomly treated with ERL or SRP in a split-mouth design.

Treatment of periodontal defects in dogs using an injectable composite hydrogel/biphasic calcium phosphate.

An injectable composite silanized hydroxypropyl methyl cellulose/biphasic calcium phosphate (Si-HPMC/BCP) has been investigated in humans with promising results. The aim of this study was to evaluate his efficacy for treating periodontal defects (canine fenestration and premolar furcation) in dog models. At 3 months, we observed that bone formation around BCP particles in furcation model is more discernible but not statistically significant in defects filled with Si-HPMC/BCP compared to healing in control.

Laser-induced fluorescence for subgingival calculus detection: scientific rational and clinical application in periodontology.

Objective: To review the data available on the laser-induced calculus fluorescence phenomenon and the calculus detection devices as well as to determine the clinical relevance of using commercialized calculus detection devices in periodontal treatment.

Methods: In vitro or in vivo English publications found on Medline.

Results: In vitro and in vivo studies showed that the devices on the market had a satisfactory detection capacity.

Tooth desensitization with an Er:YAG laser: in vitro microscopical observation and a case report.

Tooth hypersensitivity is a frequent condition that causes discomfort and sometimes severe pain. It is caused by exposure of spots of dentinal tubules to the oral environment. Conventional desensitizing agents (professional pastes, toothpastes, mouthwashes) aim to obliterate the exposed dentinal tubules.

Experimental animal models in periodontology: a review.

In periodontal research, animal studies are complementary to in vitro experiments prior to testing new treatments. Animal models should make possible the validation of hypotheses and prove the safety and efficacy of new regenerating approaches using biomaterials, growth factors or stem cells. A review of the literature was carried out by using electronic databases (PubMed, ISI Web of Science).

[Orthodontic tooth displacement: histology, biology and iatrogenic effects].

Iatrogenic effects of orthodontic forces, in particular root resorption, are described in the literature. However, our knowledge on the risk of osseous defects induced by orthodontic treatment is still scarce. After an overview of histological and biological principles of orthodontically-induced tooth movement, this study focuses on the recent data concerning the occurrence and the treatment of bone resorption associated with orthodontic treatment.

Effect of gingival and dental plaque antiseptic decontamination on nosocomial infections acquired in the intensive care unit: a double-blind placebo-controlled multicenter study.

Objective: To document the effect of gingival and dental plaque antiseptic decontamination on the rate of nosocomial bacteremias and respiratory infections acquired in the intensive care unit (ICU).

Design: Prospective, multicenter, double-blind, placebo-controlled efficacy study.

Setting: Six ICUs: three in university hospitals and three in general hospitals.
