Brief summary
Ribonucleic acids (RNA) are molecules that transfer genetic information from the nucleus to the cytoplasm for protein translation. A subgroup of non-coding or non-messenger RNAs, known as microRNAs (miRNAs), regulates the expression of complementary mRNAs without coding for proteins. In this study, the investigators aimed to evaluate the effect of systemically administered oral isotretinoin on gingival health in terms of microRNA (miRNA), a molecule of interest in periodontal research, before, during, and after treatment.
Detailed description
Healthy participants (n:25) enrolled for this study. Samples will be collected for each patient at the following time points: immediately before the initiation of retinoic acid treatment, during treatment at week 5 (T1), during treatment at month 5 (T2), and three months after the end of treatment (T3).
Interventions
Saliva were collected to analyze the selected markers as unstimulated samples during the early hours of the day. The saliva was centrifuged and then transferred into Eppendorf tubes. Venous puncture was performed after saliva collection and 10 mL of blood samples were collected by qualified staff from each participant (Periopaper, Oraflow Inc., Plainview, NY, USA). Saliva, serum were then stored at -80 °C until analysis.

Eligibility
Inclusion criteria
* systemically healthy * over 18 and under 45 years of age * have at least 20 natural permanent teeth in occlusion excluding third molars, * not be pregnant, * have not used any antimicrobial and/or anti-inflammatory drugs in the past 3 months, * have not received periodontal treatment in the past 6 months, * have not undergone surgical periodontal treatment within the past year.
Exclusion criteria
* history of regular use of systemic antibiotics anti-inflammatory, or antioxidant drugs (previous 3 months) * nonsurgical periodontal treatment (previous 6 months) * surgical periodontal treatment (previous 12 months) * current medications affecting gingival health (calcium channel blockers, phenytoin, cyclosporine, and hormone replacement therapy) * pregnancy
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Bleeding on probing | 6 months | referring to bleeding that is induced by gentle manipulation of the tissue at the depth of the gingival sulcus, or interface between the gingiva and a tooth. |
| Pocket probing depth | 6 months | Measurement of the depth of a sulcus or periodontal pocket determined by measuring distance from a gingival margin to the base of the sulcus or pocket with a calibrated periodontal probe. |
| Clinical attachment level | 6 months | Clinical attachment level (or loss, CAL) is a more accurate indicator of the periodontal support around a tooth than probing depth alone. CAL is measured from a fixed point on the tooth that does not change, the CEJ. To calculate CAL, two measurements are needed: distance from the gingival margin to the CEJ and probing depth. In recession: probing depth (+) gingival margin to the CEJ (add). In tissue overgrowth: probing depth (-) gingival margin to the CEJ (subtract) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Saliva, serum samples processing and analyses | 1 month | Saliva, serum samples obtained for each patient were used for cytokine analysis. Prepared samples were analyzed for TNF-a using commercial ELISA kits. RT-qPCR-based miRNA gene expression analyses will be performed using Two-Step qRT-PCR Kits (Thermo Fisher Scientific, MA, USA). |
