Brief Summary

This prospective cohort study analysed the effects of systemic retinoic acid use on periodontal status, salivary flow rate (SFR), and salivary and serum levels of interleukin (IL)-1β, IL-8 and monocyte chemoattractant protein (MCP)-1.

Outcome Measures

Primary Outcomes (3)

  • bleeding on probing

    To assess the inflammatory status of the pocket base and pocket epithelium, bleeding was recorded 30 seconds after probing depth measurement. The presence of bleeding was scored as positive (+), while the absence of bleeding was recorded as negative (-). The percentage value of the Bleeding on Probing for each patient was calculated using the following formula: (Number of bleeding surfaces / Total number of tooth surfaces) × 100

    at 4 time point: before retinoic acid treatment, during(6th week and 5th month) retinoic acid treatment and 2nd month after completion of retinoic acid therapy

  • IL-1beta, IL-8 and MCP-1 levels

    Interleukin(IL)-1beta, IL-8 and monocyte chemoattractant protein (MCP)-1 are inflammatory cytokines which show inflamatory changes.

    at 4 time point: before retinoic acid treatment, during(6th week and 5th month) retinoic acid treatment and 2nd month after completion of retinoic acid therapy

  • salivary flow rate

    Salivary flow rate was calculated by the collected saliva volume SFR=Volume of saliva (mL) collected in 10 minutes/10 minutes.

    at 4 time point: before retinoic acid treatment, during(6th week and 5th month) retinoic acid treatment and 2nd month after completion of retinoic acid therapy

Study Arms (1)

retinoic acid users

A total of 24 periodontally healthy participants who were prescribed isotretinoin (Retinoic acid) (0.5-1 mg/kg/day) for six months to treat moderate to severe acne vulgaris or nodular acne, based on the Global Acne Grading System, were included in the study.
