Abstract
Introduction: There are various theories of the origin of areas with
high radiation density in the fungal ball of the paranasal sinuses: X-ray
contrast dentist filling material; accumulation of zinc due to enzymes of
the metalloproteinase group; formation of osteophytes, etc.
The purpose of the study: to study the chemical composition of areas
of fungal balls that have high radiological density.
Methods and materials: The results of research of 26 samples of
fungal bodies by scanning electron microscopy and spectrometry removed from
maxillary sinuses in patients with fungal sinusitis (4 – nonodontogenic, 22
– odontogenic origin) are presented. In addition, 5 types of material most
commonly used for endodontic treatment were studied.
The results: It was found that fungal bodies of odontogenic origin
have a heterogeneous structure with the presence of crystalline inclusions,
the elemental composition of which has the characteristics of materials for
endodontic treatment (Ba, Zr, W, Co), or increased content in the fungal
ball of trace elements (Ti, Al and Zn), in quantities that are not
characteristic of organic compounds.
Conclusions: Scanning electron microscopy in combination with
spectrometry can be used to identify foreign bodies of the maxillary sinus
of exogenous (iatrogenic) origin and determine their role in the development
of the fungal ball. |
