Abstract

Objective: This study compared the concentration of salivary lactoferrin in patients with and without chronic periodontitis and investigated correlations with clinical variables of the disease.


Methods: The study included 102 participants (51 cases and 51 controls) who presented at the Periodontology Clinic of University of Benin Teaching Hospital and met the selection criteria of ‘4mm and above’ periodontal probing depths (PPD) and positive bleeding on probing (BOP) using community periodontal index (CPI) probe. Healthy participants (controls) were patients that had PPD less than or equal to 3mm, absence of BOP and simplified oral hygiene index (OHI-S) not more than 1.2. Baseline OHI-S and CPI scores were recorded. Saliva samples were collected and analyzed using enzyme-linked immunosorbent assay. All data were analyzed with the Statistical Package for Social Sciences (SPSS) version 22.0.


Results: There was a statistically significant difference between the mean (SD) lactoferrin concentration of control participants 5.27(0.59) mg/l and case participants 6.74(0.61) mg/l (p<0.001). Participants with probing pocket depths (PPD) of 6mm or more had a significantly higher mean concentration [6.85(0.06) mg/l] than that of those with PPD 4-5mm [6.71(0.67) mg/l] (p < 0.001) Lactoferrin levels were highest in participants with ‘poor’ oral hygiene [6.85(0.60) mg/l] and lowest in those with ‘good’ oral hygiene [6.65(0.83) mg/l].


Conclusion: Salivary lactoferrin levels were higher among participants with chronic periodontitis than those without chronic periodontitis and correlates positively with the main clinical characteristics of the disease
