Stress and periodontal health

Periodontitis and periimplant infections are complex manifestations associated with several disease-modifying factors, such as causative pathogens and smoking. Although research into these factors has led to important progressions in the treatment of these infections in recent decades, the contribution of mental stress in the absence of pathogens or smoking is still unclear. Qualitative and quantitative assessment of mental stress might be an important instrument in periodontal and periimplant therapy.
