Effect of bleaching on tooth discolouration from food colourant in vitro.

Objectives: The purpose of this study was to evaluate the effect of bleaching on tooth discolouration from neutral food colourant media (NFCM).

Methods: Freshly extracted human molar teeth (n = 32) were divided into four groups (n = 8): non-bleached treatment-NBT, non-bleached control-NBC, bleached treatment-BT and bleached control-BC. Bleached teeth specimens were subjected to 20% carbamide peroxide bleaching agent for 10h.

Effect of pH on tooth discoloration from food colorant in vitro.

Objectives: The purpose of this study was to evaluate the effect of acidic, neutral and alkaline food colorant media (FCM) on tooth discoloration in vitro.

Methods: Treatment (n=24) and control (n=24) sterile, hydrated human molars were prepared in individual, impervious holders and their color measured (pretest) using a non-contact spectroradiometer system. Specimens were randomly assigned to and immersed in one of the three buffer solutions (pH 2, pH 7 or pH 12).

Eating disorders: screening in the dental office.

Background: Eating disorders are serious illnesses that often are not detected by health care professionals. The author presents techniques that the oral health care professional (OHCP) can use to screen at-risk patients for eating disorders during routine preventive care appointments.

Conclusions: OHCPs often are the first health care professionals to encounter patients with undiagnosed eating disorders.

Weighing in on weight screening in the dental office: practical approaches.

Background: Being overweight and being obese are systemic and oral health risks, as well as global health problems. The authors present weight-screening strategies for adults that are simple, reliable, valid and realistic to use in the dental practice.

Conclusions: Conducting routine weight screening in dental practices is supported by the multifaceted relationship among body weight, oral health and the "globesity" epidemic.

Advanced caries in a patient with a history of bariatric surgery.

Purpose: The rate of bariatric surgery in the United States has risen significantly in the past decade as the prevalence of extreme obesity continues to increase. Although bariatric surgery is an effective therapeutic modality for extreme obesity, it is associated with risk factors and select oral health conditions. This case study describes a patient with a significant increase in dental caries after having gastric bypass surgery.

Efficacy of an automated flossing device in different regions of the mouth.

Background: Manual floss is often difficult to use, particularly in hard to reach posterior teeth. Many prefer automated flossers because of their ease of use. The aim of the present study was to compare the effectiveness of an automated flosser to manual floss for anterior, premolar, and molar teeth using the plaque index (PI) and gingival (GI) index.

Evaluation of the safety and efficacy of an automated flossing device: a randomized controlled trial.

Objective: To evaluate the safety and efficacy of a newly developed automated flossing device (AF).

Methodology: Subjects were recruited from a university campus via announcements, and were randomly assigned to a control (C), manual (M), or automated (A) group. Subjects brushed twice a day and treatment groups used their respective floss daily.

Web-based intervention for changing attitudes of obesity among current and future teachers.

Objective: To evaluate attitude change among student teachers and schoolteachers when exposed to a Web-based educational module promoting size acceptance.

Design: Subjects were randomly assigned to a control group or 1 of 4 treatment groups to evaluate the effect of module, presenter credibility, and/or image on attitudes of obesity and processes of change using the Elaboration Likelihood Model (ELM) testing cognitive and psychological cues. On-line assessment occurred at the pretest, posttest, and 6-week follow-up.
