Background: The Single Ventricle Reconstruction (SVR) Trial was the first randomized clinical trial of a surgical approach for treatment of congenital heart disease. Infants with hypoplastic left heart syndrome (HLHS) and other single right ventricle (RV) anomalies were randomized to a modified Blalock Taussig Thomas shunt (mBTTS) or a right-ventricular-to-pulmonary-artery shunt (RVPAS) at the time of the Norwood procedure. The aim of the Long-term Outcomes of Children with HLHS and the Impact of Norwood Shunt Type (SVR III) study is to compare early adolescent outcomes including measures of cardiac function, transplant-free survival, and neurodevelopment, between those who received a mBTTS and those who received an RVPAS.

Purpose: To evaluate the plaque removal efficacy and safety of an advanced rotation-oscillation power toothbrush relative to a newly-introduced sonic toothbrush.

Methods: This study used a randomized, examiner-blind, two-treatment, four-period, four-sequence crossover design. Subjects received both toothbrushes (Oral-B Triumph and Sonicare FlexCare) and a standard dentifrice from the study site and used each toothbrush at home during an acclimation phase prior to their plaque measurement visits.

Esophagitis and esophageal strictures are relatively uncommon but significant diseases in companion animals. Often, an esophageal disorder is suspected on the animal's medical history and clinical signs. Esophagitis and acquired esophageal strictures are caused by prolonged contact of caustic substances or foreign bodies with the esophageal lining, leading to mucosal injury.

Purpose: To assess the in vivo plaque removal efficacy of the newly marketed sonic/ultrasonic toothbrush. Plaque removal resulting from the toothbrush being held approximately 3 mm from the tooth surface was compared versus a no brushing control. Also, plaque removal resulting from the brush being used according to the manufacturer's instructions was compared versus a control of using the brush (with power turned off) like a manual toothbrush would be used.

Background: While early spinal fusion may halt progressive deformity in young children with scoliosis, it does not facilitate lung growth and, in certain children, it can result in thoracic insufficiency syndrome. The purpose of this study was to determine pulmonary function at intermediate-term follow-up in patients with scoliosis who underwent thoracic fusion before the age of nine years.

Methods: Patients who had thoracic spine fusions before the age of nine years with a minimum five-year follow-up underwent pulmonary function testing.

Aim: To compare the safety and efficacy of two manual toothbrushes, Oral-B Exceed and Asian Colgate 360 masculine, in removing plaque.

Methods And Materials: The study used an examiner-blind, two-treatment, randomized, four-period (visits) crossover design. At the first visit, subjects received a baseline plaque examination; plaque was scored using the Rustogi et al.

Objective: To evaluate the safety and plaque removal efficacy of an advanced rotating-oscillating power toothbrush relative to a sonic toothbrush with either a standard or compact brush head.

Methodology: Two studies used a randomized, examiner-blind, two-treatment, crossover design. In Study 1, subjects were instructed to use their first randomly assigned toothbrush for five to seven days and then, after abstaining from all oral hygiene for 24 hours, were assessed with the Rustogi, et al.

Objective: To evaluate the safety and efficacy of two power toothbrushes in the removal of dental plaque following a single brushing.

Methods: The study employed a two-treatment, examiner-blind, randomized, four-period crossover design. A total of 25 generally healthy adult subjects were enrolled into the study.

Aim: The aim of this article is to provide a review of common power toothbrush technologies with a focus on the oscillating-rotating motion used in a novel toothbrush; describe features to drive compliance such as the "SmartGuide" innovation; and finally recommend steps to motivate patients to adopt a power toothbrush as part of their home care regimen.

Background: Contemporary power toothbrushes are available with various modes of actions, bristle designs, and features. Clinical research shows these factors can impact the effectiveness of a toothbrush by altering its ability to remove plaque, particularly in areas that are difficult to access.

Dentinal hypersensitivity is generally reported by the patient after experiencing a sharp pain caused by one of several different stimuli. The pain response varies substantially from one person to another. The condition generally involves the facial surfaces of teeth near the cervical aspect and is very common in premolars and canines.

Objective: The objective of this four-week, examiner-blind study was to determine the impact of an educational oral health program conducted within a Boys and Girls Club of America in Chicago, Illinois, USA. The educational program focused on the gingival health (gingivitis and plaque) of participating children who were between the ages of six and 15.

Methodology: The multi-week program taught the participants the basics of oral biology and disease, as well as proper oral health prevention, including oral hygiene, dietary modification, and the importance of visiting the dentist.

The 2-period, randomized, double-blind, placebo-controlled, crossover study compared the stain-prevention and stain-removal benefit of a chewing gum containing 7.5% sodium hexametaphosphate (measured by digital image analysis) with a placebo chewing gum. The results of this study support that sodium hexametaphosphate delivered from a chewing gum prevents dental stain formation and facilitates stain removal, which leads to a perceptible whitening benefit.

Whitening dentifrices have recently become popular, achieving a whitening benefit by surface chemical action and/or abrasion that serve to remove extrinsic stains and/or prevent extrinsic stain buildup. Some powered toothbrushes have also been demonstrated to have whitening/stain-removal efficacy when used with standard dentifrice products. The objective of this study was to evaluate the effectiveness of an experimental prototype powered toothbrush (Crest SpinBrush Pro) and a commercially available powered toothbrush (Crest SpinBrush) on dental whitening through the removal of extrinsic stain.
