Background: This study evaluates the effect of periodontitis on masticatory performance and quality of life index.

 Methods: Patients (n = 24 23 to 76 years of age) with periodontal conditions ranging from healthy to generalized disease categorized by the alveolar bone height–to–tooth length (AB/T) ratio were separated into the following two groups: control (AB/T >50%) and test (AB/T <50%). The masticatory performance was evaluated through continuous mastication of a special device called a biocapsule. The Brazilian Oral Health Impact Profile (OHIP-14Br) questionnaire was used to assess the oral health–related quality of life. The Student t test was applied for independent samples (P <0.05) to evaluate the masticatory performance, and the Mann-Whitney U test was used to determine quality of life (P <0.05)

 Results: There was a statistically significant difference in masticatory efficiency between groups (P = 0.006). Statistically significant differences were also observed in the following parameters: 1) physical pain (P = 0.003) 2) psychologic discomfort (P = 0.008) 3) physical disability (P = 0.033) and 4) OHIP-14Br total score (P = 0.001). The control group achieved the best indicators. Both the masticatory performance and quality of life indicators showed significant correlation with the alveolar bone height.

 Conclusion: The loss of periodontal supporting structures has negative effects on the masticatory performance and quality of life.
