OCT investigations of dental biofilm

Abstract

The present study explores the capabilities that OCT has to serve for the study of biofilm deposition, eventually in conjunction with other investigation methods. The investigations were carried out on two directions: (i) to evaluate different methods for manufacturing dental prostheses, with the scope to identify a correlation between the design of the fixed partial prostheses pontic’s and the cytodiagnostic of the covering gingiva of the edentulous ridge and the gingival tissue around the abutments of the fix partial prostheses; (ii) to analyze the efficiency of different cleaning methods of dentistry equipment by assessing biofilm deposition in different types of tubes employed in such equipment (considering the inside of tubes of different diameters chosen for their long usage period in order to generate significant imaging results). In both studies an in-house developed Swept Source (SS) OCT system centered at 1300 nm, with an axial resolution of 15 µm was utilized. The results showed that OCT was capable to offer quantitative evaluations of the width of biofilm deposition, complementing for example (conventional) microbiology investigations.
