EXECUTIVE SUMMARY Purpose: Tooth brushing is the most commonly recommended and performed oral hygiene behaviour by North Americans and is done ubiquitously in developed nations. It is the primary mechanical means for removing dental plaque, thereby assisting in the prevention of oral diseases including gingivitis and dental caries. The aim of this paper is to report on an investigation of the c...

OBJECTIVE The aim of this study was to evaluate the susceptibility of dentin to brushing abrasion using four different toothbrushes (rotating-oscillating, sonic and two types of manual toothbrushes) with the same brushing forces. METHODS Dentin samples (n = 72) were selected from 72 impacted third molars. Half of the surface of dentin samples was covered with an adhesive tape, creating a prot...

Abstract Disk-shaped specimens were prepared from additively (NX and DT), subtractively (MZ), conventionally manufactured denture base resins (CV). Surface roughness color coordinates measured after polishing, simulated brushing, coffee thermocycling, while surface was also before polishing. Polishing reduced the of all materials. Brushing thermocycling increased only DT. CV had highest suscept...

Dentifrice abrasiveness and brushing time may increase color change (∆E) and surface roughness (∆Ra) of resin composites. This study aimed to evaluate the effect of mechanical brushing time of dentifrices with different abrasiveness on ∆E and ∆Ra of nanofilled (Z350, 3M ESPE) and nanohybrid (Tetric N-Ceram, Ivoclar Vivadent) resin composites. Sixteen specimens (12 mm diameter x 2 mm thick) were...

Toothbrushing is fundamental to oral hygiene. Children differ in manual dexterity and their grip on toothbrushes. We videotaped toothbrushing sessions and observed the grip type, duration of brushing, and brushing technique used among 100 children aged 8-12 years. We then investigated the association between grip type and plaque removal, using plaque scores obtained at various time points. We f...

STATEMENT OF PROBLEM Inadequate tooth brushing and inappropriate oral hygiene can lead to dental caries, the most common chronic diseases of childhood with several side effects. OBJECTIVES To evaluate factors affecting on preschool children's oral hygiene and tooth brushing in Shiraz, Iran. MATERIALS AND METHODS In this cross-sectional study, we selected 453 children registered in Shiraz ki...

The use of toothbrushes has significantly improved oral hygiene. However, if brushing of the teeth is not done judiciously, it could result in severe trauma to the soft tissues of the oral cavity. This is particularly true in the young age group, since children tend to be very playful while brushing their teeth. This article describes the case report of a child who sustained a penetrating injur...
