Dental fluorosis – A disease that is brought about by over intake of fluoride during the formation of the teeth usually leaves white, brown or pitted marks on the teeth, which are unattractive. Although this is a rather cosmetic issue, serious cases of fluorosis might have a major impact on self-esteem and the looks of a smile.
A question that has been asked is: Does dental composite bonding have the capability of covering the severe fluorosis stains? The brief response is yes, though some considerations and techniques are very crucial.
Comprehending Dental Composite Bonding
Composite bonding is the procedure of adhering a dentin-colored resin medium to the surface of the teeth to cover up any color changes and to replicate a natural appearance. It is also attributed to being least invasive, cost efficient, and providing immediate outcomes of mild to moderate fluorosis on the first visit.
However, severe fluorosis is rather challenging. Enamel of extremely fluorosed teeth is very mineralized and resistant to acid thus making the adhesion of the composite material more difficult. This implies that regular bonding processes might not result in long-term and continuous coverage.
Problems of Bonding on Severe Fluorosis
Scientific findings indicate that extreme fluorosis adversely affects the strength of the bond of resin composites because of the distorted enamel structure. Hypermineralization of the surface enamel occurs and the enamel becomes resistant to etching that is a necessary process to rough the surface so as to enable good adhesive bonding. Composites will not stick well without adequate preparation and will possibly peel or have discoloured appearance.
Optimizing Bonding in Severe Fluorosis amongst Dentists
In order to overcome these obstacles, dental specialists use improved guidelines:
Long etching durations: Phosphoric acid etching is continued longer than 15-30 seconds up to 90 seconds or longer in order to reach the resistant enamel.
Mechanical removal: An often used method to expose a more bondable enamel layer underneath is by microabrading, air abrasion, or delicate drilling of the hypermineralized layer of surface.
Selective adhesive systems: Etch-and-rinse enamel adhesive with a self-etching dentin primer are the most effective bonding agents.
Multiple layering method: This technique consists of several layers of composite resin, which are molded to give a natural contour of the tooth and cover stains completely.
What is the Appropriateness of Composite Bonding?
The composite bonding is also suitable in cases of severe fluorosis where the patient is not willing to see their teeth reduced substantially. But it is most essential to live long, which is determined by careful method and post-care.
In cases of very severe fluorosis (deep enamel defects or pitting) or in cases where maximum durability and stain resistance is required, instead veneers or crowns can be considered.
Maintenance and Longevity
Attached teeth demand good oral health and frequent dentists visits. Although composite bonding may last several years, the patients must remember that over time it may require a touch-up or replacement because of wear or color changes.
Final Answer
In experienced hands of highly qualified dentists applying superior bonding techniques, dental composite bonding is able to cover the worst of fluorosis.
