EFFECT OF HYDROXYAPATITE TOOTHPASTE ON REMINERALIZATION OF PRIMARY TEETH VERSUS FLUORIDE TOOTHPASTE
Marwa Gamal Nazief;
Abstract
The surface enamel has received particular attention, because of its significant resistance to the initiation of dental caries.
Modern dentistry has evolved to a minimally invasive approach, in which caries is managed as an infectious disease, deferring operative intervention as long as possible. The focus is on maximum conservation of demineralized, noncavitated enamel and dentin.
Use of some toothpastethat has been showed to possess different properties of remineralization and/or repair of the enamel surface may help to protect tooth enamel.
Accordingly, the aim of this study was to evaluate the effect of hydroxyapatite toothpaste with fluoride; on the remineralization of human enamel in comparison to another toothpaste containing fluoride only using Scanning Electron Microscopy (SEM) and Micro hardness test.
A total of eighteen human primary teeth were collected with sound or spot (shallow caries) enamel at the time of their exfoliation. Teeth were cut mesiodistally into two equal halves using a Diamond stone size 2, mounted on a low speed straight hand piece with copious water irrigation & the roots of the teeth were cut using the same diamond stone.
The enamel slabs were etched with 37.5% Phosphoric acid gel for 30-60 seconds; etched slabs were washed with distalled water. Afterwards slabs were divided into three groups according to treatment modality and the method of the evaluation. All the slabs were investigated before and after remineralization this were done by Scanning Electron Microscopy (SEM) and microhardness testing.
Results were tabulated showing that the HAP & FL toothpaste group had the highest value of micro hardness compared to the F toothpaste group and control group.
