Abstract.
The purpose of the present research was to reveal sensibilization to titanium dioxide in patients with intolerance to dental alloys galvanized with titanium nitride.
We conducted an examination of 47 patients complaining of intolerance to punched-soldered orthopedic constructions from stainless steel galvanized with titanium nitride. The age of patients varied from 39 to 76 years, among them were 11 men and 36 women. The control group included 30 practically healthy subjects comparable with regard to their gender and age to patients of the studied group.
It has been established that in patients with intolerance to dental alloys, galvanized with titanium nitride, sensibilization to titanium dioxide was revealed using diagnosing results, the reaction of allergen induced damage of leukocytes, in 16 (34%) patients that reliably differed (p≤0,05) from 3 (10%) positive results obtained in the control group (n=30).
We found out the existence of direct strong correlation (R=0,76; p≤0,05) between the results of detecting hypersensitivity to TiO2 and Ti-Ni defined in the reaction of allergen induced damage of leukocytes, this indicates the combined influence of various substances on the oral cavity mucosa, with general hypersensitivity inductor – Ti2+.
It has been shown that titanium dioxide is capable to induce the appearance of symptoms of stomatologic materials intolerance owing to its broad all-round use in cosmetic production, food and pharmaceutical industry and continuous impact of these substances on the oral cavity mucosa.
The problem of intolerance to dental alloys galvanized with titanium nitride is complex. When patients complain of intolerance, it is necessary to study them concerning their hypersensitivity to titanium dioxide.
Key words: hypersensitivity, titanium dioxide, titanium nitride.
