Aim: To evaluate the levels of two putative periodontal pathogens, Porphyromonas gingivalis (Pg) and Prevotella intermedia (Pi), in plaque samples of mentally depressed patients.
Materials and methods: A total number of 110 patients clinically diagnosed to have mental depression by the psychiatrist, in the age range of 20–50 years, were included. Clinical parameters such as gingival index, plaque index, and clinical attachment level were recorded. Samples of supragingival plaque were sent to the microbiology lab for culturing.
Results: Collected plaque samples exhibited elevated amounts of Pi and Pg on culturing. The levels of pathogens (Pg and Pi) were more in patients with greater attachment loss.
Conclusion: This preliminary study showed that mental depression might alter the periodontal microflora of mentally depressed individuals towards a more pathogenic one.
Clinical significance: Elevated levels of Pg and Pi in plaque samples of mentally depressed individuals can increase the susceptibility to periodontitis, deteriorate mental well-being, and aggravate periodontal destruction.
