title: The effect of mechanical oral hygiene procedures on bleeding on probing.
abstract: The purpose of the present study was to investigate the effect of mechanical oral hygiene procedures on bleeding on probing in relation to age and periodontal status. The study was carried out on 49 individuals divided into 7 experimental groups according to age and having been either treated for destructive periodontal disease or having an intact healthy periodontium. In order to eliminate any pre-existant gingival inflammation, all subjects received a carefully controlled oral hygiene program. At the start of the experiment, all subjects were instructed to abstain from oral hygiene procedures for 24 h. Thereafter, clinical baseline measurements were carried out, including bleeding on probing (BOP) using a standardized probing pressure. Next, all subjects cleaned their teeth according to their normal oral home care protocol using a multitufted toothbrush, toothpicks and interdental brushes. BOP scores were again assessed 30 min after completed tooth cleaning procedures. The results revealed a significant increase in BOP after the mechanical oral hygiene procedures in every individual in all experimental groups (p less than 0.05). Further analysis showed that the increase in BOP was independent of the periodontal status of the subjects. However the BOP scores after mechanical oral hygiene procedures were higher in the young age groups. It was concluded that the diagnostic predictability of BOP in the treatment of periodontal diseases might be affected by temporarily elevated BOP scores shortly after mechanical oral hygiene procedures.
