Unusual incisor tooth wear: A diagnostic sign of dietary habits [PDF]

Acta Stomatologica Naissi
Introduction: Dentists frequently encounter cases of tooth wear, which can be caused by a variety of reasons, such as food erosion, physical attrition, and abrasion due to contact with foreign objects.

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).

Poly(alkyl methacrylate) tooth coatings for dental care: evaluation of the demineralisation-protection benefit using a time-resolved in vitro method [PDF]

, 2011
An in vitro method for the time-resolved quantification of acid-mediated tooth demineralisation has been developed and evaluated against putative non-permanent protective formulations based on a series of poly(alkyl methacrylate)s.

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 ...

A profilometric and scanning electron microscopic analysis of tooth surface abrasion caused by rotary/oscillatory, linear motion, sonic, and ultrasonic toothbrushes: An in vitro study

Journal of Indian Society of Periodontology, 2021
Background: Adequate plaque control facilitates good gingival and periodontal health, prevents tooth decay, and preserves oral health. Toothbrushing is the primary method of removing plaque and can be classified into powered and manual toothbrushes. Aim:

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.

Susceptibility of fluorotic enamel to dental erosion-abrasion

, 2023
Dental hard tissue conditions can be of pre- or post-eruptive nature, such as enamel fluorosis and erosive tooth wear (ETW), respectively. Dental enamel fluorosis is caused by the chronic and excessive intake of fluoride during enamel development ...

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 ...
