Study of the pathogen levels on implant abutments with different coating characteristics
Abstract:
The aim of the present study was to obtain preliminary data on the levels of pathogens according to their DNA concentration in patients with implant abutments of two different surface characteristics.
Material and method: Fifty patients from the city of Sofia treated with dental implants were subjected to a quantitative molecular biological analysis of microorganisms: 25 of the patients received implants with titanium nitride-coated abutments and 25 were treated with implants with titanium nitride-uncoated abutments.
Results: The quantitative molecular biological analysis of microorganisms performed showed no significant association with the presence or absence of coating. Patients in both groups had similar relative proportions of Pg (p = 0.225), Td (p = 0.571), Tf (p = 0.333), Pi (p = 0.758), Pm (p = 0.089), Fn (p = 0.087), En (p = 0.110), Cg (p = 0.774).
The above results justify the need of further and more detailed quantitative molecular-biological analysis of microorganisms in patients treated with dental implants and abutments of different surface characteristics.
Keywords: oral pathogens, implant abutments, coating characteristics
