Introduction:

Dental procedures have been associated with bacteriemia and infective endocarditis.

Objective:

To determine the prevalence of infective endocarditis from dental procedures.

Materials and methods:

A descriptive, retrospective quantitative study was carried out. Records of infective endocarditis of which the general identification, sex, age, socioeconomic status, dental procedure report, type of dental procedure and non-specified infective endocarditis information was collected. Additionally, information was recorded on the type of medical/surgical procedure or medical condition that was associated. Categorical variables are presented as absolute and relative frequencies. The data were compiled in a spreadsheet for processing in statistical software (SPSS ver. 25).

Results:

Of the 154 cases of infective endocarditis registered, only 1 case (0.7%) reported an endodontic-type dental procedure prior to hospitalization. The most reported related cause was catheterization for hemodialysis (37%) followed by unspecified bacteriemia (22%) and cardiovascular condition associated with heart valves and pacemakers (18.8%). In 15.6% of the cases, it was reported as non-specific infective endocarditis. The most isolated microorganisms belonged to the genus Staphylococcus followed by Streptococcus.

Conclusions:

The frequency of bacterial endocarditis related to dental procedures was less than 1%. Medical-surgical procedures remain the most common cause of bacterial endocarditis.
