This study aims to evaluate, through clinical and microbiologic parameters, the systemic use of azithromycin (AZ) and chlorhexidine (CHX) as adjuvants to non\u2010surgical periodontal treatment performed by one\u2010stage full\u2010mouth disinfection (FMD) within 24 hours or conventional quadrant scaling (QS) in four weekly sections.<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold> In this randomized controlled trial, 85 patients diagnosed with chronic periodontitis underwent different treatment protocols, in six groups: three FMD groups and three QS groups, each with no adjuvants, with CHX, and with AZ. Clinical periodontal parameters were recorded, and total and quantitative bacterial counts of <jats:italic>Aggregatibacter actinomycetemcomitans<\/jats:italic>, <jats:italic>Porphyromonas gingivalis<\/jats:italic>, <jats:italic>Tannerella forsythia<\/jats:italic>, <jats:italic>Treponema denticola<\/jats:italic>, and <jats:italic>Streptococcus oralis<\/jats:italic> were measured with real\u2010time polymerase chain reaction at baseline and 90 and 180 days after treatment.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> In all groups, a significant reduction was observed in the percentage of periodontal diseased sites, gingival index, plaque index, and clinical attachment level gain at 90 days, demonstrating effectiveness of the treatment, independently of the adjuvant. The FMD with CHX group showed higher reduction in probing depth and percentage of periodontal diseases sites, as well as lower total bacterial count, than all the other groups at 180 days.<\/jats:p><jats:p><jats:bold>Conclusions:<\/jats:bold> The adjuvant use of AZ did not provide any significant benefit, independently of the treatment protocol. The adjuvant use of CHX showed a more expressive and significant improvement in clinical and microbiologic parameters, especially in the FMD protocol, followed by
