Risk factors for tooth wear lesions among patients attending the dental clinic of a Nigerian Teaching Hospital, Benin City: A pilot study

Sahel Medical Journal, 2015
Aims: This study was to evaluate the risk factors associated with tooth wear lesions in patients attending a dental clinic. Context: Tooth wear lesions entail the loss of dental hard tissues in the absence of caries or trauma.

Is prolonged bleaching more harmful to dental enamel than daily dietary and hygienic oral habits?

Brazilian Oral Research, 2021
The ultrastructural and mechanical properties of enamel surface were evaluated after prolonged bleaching treatments with 10% carbamide peroxide in the presence or absence of orange juice (erosive challenge) and toothbrushing (abrasive challenge).

Use of dentifrices to prevent erosive tooth wear: harmful or helpful?

Brazilian Oral Research, 2014
Dental erosion is the loss of dental hard tissues caused by non-bacterial acids. Due to acid contact, the tooth surface becomes softened and more prone to abrasion from toothbrushing.

Influence of chemical degradation and abrasion on surface properties of nanorestorative materials

Brazilian Journal of Oral Sciences, 2015
Aim: The aim of this in vitro study was to investigate the synergistic effect of chemical degradation (erosion) and three-body abrasion (mechanical degradation) on the surface roughness (Ra) and hardness (KHN) of two nanorestorative materials and two ...

Detecting inter-cusp and inter-tooth wear patterns in rhinocerotids. [PDF]

PLoS ONE, 2013
Extant rhinos are the largest extant herbivores exhibiting dietary specialisations for both browse and grass. However, the adaptive value of the wear-induced tooth morphology in rhinos has not been widely studied, and data on individual cusp and tooth ...

Relationship between handedness and toothbrush-related cervical dental abrasion in left- and right-handed individuals

Journal of Dental Sciences, 2010
Background/purpose: Cervical tooth abrasion is the loss of tooth material at the cementoenamel junction, and is usually related to faulty brushing habits.

Tooth surface loss: A review of literature

Saudi Dental Journal, 2020
Objectives: Tooth surface loss (TSL) or tooth wear (TW) is an irreversible loss of hard tooth structure caused by factors other than those responsible for dental caries. TSL is observed clinically as attrition, abrasion, abfraction, and erosion.

Abrasion wear resistance of different artificial teeth opposed to metal and composite antagonists

Journal of Applied Oral Science, 2009
One of the most important properties of artificial teeth is the abrasion wear resistance, which is determinant in the maintenance of the rehabilitation's occlusal pattern. OBJECTIVES: This in vitro study aims to evaluate the abrasion wear resistance of 7

齿轮动力互研法的工艺研究

Jixie chuandong, 1999
The method of gear dynamic mutual abrasion is a method in which the dynamic force on tooth surface was used to do the precision finishing. In order to avoid the “midconvex” of tooth profile and the serious abrasion in dedendum, the technology of center ...

ANALYSIS OF THE BIOELECTRICAL ACTIVITY OF THE MASTICATORY MUSCLES, DEFINED ACCORDING TO BERNOULLI'S PRINCIPLE AS "STRONG" OR "FAST", FOR THE PREDICTION OF PATHOLOGICAL TOOTH ABRASION (ACCORDING TO MAGNETIC RESONANCE IMAGING AND ELECTROMYOGRAPHIC STUDIES)

Український стоматологічний альманах
Pathological abrasion is a well-known disease, but it is topical issue of hard dental tissues. The principle of D. Bernoulli and its numerical expression in the form of the coefficient “k” were used.
