Abstract EN
Hydroxyapatite nanoparticles (nano-HAP) are receiving considerable attention for dental applications, and their adhesion to enamel is well established.
However, there are no reports concerning the effects of HAP on other dental materials, and most of the studies in this field are based on in vitro designs, neglecting the salivary pellicle-apatite interactions.
Thus, this in situ pilot study aims to evaluate the effects of three hydroxyapatite-based solutions and their interactions with different dental material surfaces under oral conditions.
Hence, two volunteers carried intraoral splints with mounted samples from enamel and from three dental materials: titanium, ceramics, and polymethyl-methacrylate (PMMA).
Three HAP watery solutions (5%) were prepared with different shapes and sizes of nano-HAP (HAP I, HAP II, HAP III).
After 3 min of pellicle formation, 10 ml rinse was performed during 30 sec.
Rinsing with water served as control.
Samples were accessed immediately after rinsing, 30 min and 2 h after rinsing.
Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were used to characterize the particles, and SEM evaluated the pellicle-HAP interactions.
SEM and TEM results showed a high variation in the size range of the particles applied.
A heterogeneous HAP layer was present after 2 h on enamel, titanium, ceramics, and PMMA surfaces under oral conditions.
Bridge-like structures were visible between the nano-HAP and the pellicle formed on enamel, titanium, and PMMA surfaces.
In conclusion, nano-HAP can adhere not only to enamel but also to artificial dental surfaces under oral conditions.
The experiment showed that the acquired pellicle act as a bridge between the nano-HAP and the materials’ surface.
