Brief summary

The effect of both the mechanical treatment and the topical metronidazol in reduccing the inflammation and depth of the periodontal pockets were assessed on the first bicuspids.

Interventions

PROCEDURERoot scaling

Scaling and root planing is a deep cleaning below the gumline used to remove plaque and tartar that cover the root in the periodontal pockets. This intervention is carried out in both control and experimental sites

A gel (experimental: metronidazole VS control: carbopol) is introduced in the recently cleaned periodontal pocket. The allocation of either experimental or control gel was distributed randomly, being masked both the patient and the clinician.

MeasureTime frameDescription
Probing depthBoth one month and three months after root scalingProbing depth is assessed at 6 points around the first bicuspids (mesiovestibular, midvestibular, distovestibular, mesiolingual, midlingual, distolingual)
Mieloperoxidase ng/mLBoth one and three months after root scalingThe determination of the quantity of mieloperoxidase ng/mL was assessed from the crevicular fluid of the treated bicuspids
