If the attrition is severe, the enamel can be completely worn away leaving underlying dentin exposed, resulting in an increased risk of dental caries and dentin hypersensitivity. It is best to identify pathological attrition at an early stage to prevent unnecessary loss of tooth structure as enamel does not regenerate.
Tooth wear is a complex, multi-factorial problem and there is often difficulty identifying a single causative factor. [3] However, tooth wear is often a combination of the above processes. Many clinicians, therefore, make diagnoses such as "tooth wear with a major element of attrition", or "tooth wear with a major element of erosion" to reflect ...
The goal of treatment is to preserve tooth structures and prevent further destruction of the tooth. Aggressive treatment, by filling, of incipient carious lesions, places where there is superficial damage to the enamel, is controversial as they may heal themselves, while once a filling is performed it will eventually have to be redone and the ...
Silver diamine fluoride is a clear liquid that's been used for decades in other countries, but has only recently been approved in the U.S. Dr. Amr Moursi, chair of the pediatric dentistry ...
The most important bacterium involved with tooth decay is Streptococcus mutans, but the number and type of bacteria varies with the progress of tooth destruction. [25] Furthermore, tooth morphology dictates that the most common site for the initiation of dental caries is in the deep grooves, pits, and fissures of enamel.
To prevent future buildup of extrinsic stains, identification of the cause (e.g., smoking) is required. Intrinsic discoloration generally requires one of the many types of tooth bleaching. Alternatively the appearance of the tooth can be hidden with dental restorations (e.g., composite fillings, veneers, crowns).
An increase in acidity at the tooth surface can induce demineralization and softening, therefore leaving the tooth structure susceptible to abrasive factors such as tooth brushing. [18] When the surface of the tooth structure is softened by acid, mechanical forces such as brushing can cause irreparable damage on tooth surface.
The decision on how much decay to remove (whether to carry out the decay removal to firm dentine or stop when soft dentine has been reached) depends on the depth of the cavity (a filling needs to have a minimum thickness of material to remain strong); [2] and the possibility of reaching the tooth's pulp (the nerve is exposed sometimes when deep ...
