Brief Summary

Gingival diseases occur commonly in the global population and herbal products for its intervention have limited body of research evidence. This study to evaluate the clinical efficacy of 5% thymoquinone (TQ) gel as an adjunct to scaling and root planing (SRP) in patients diagnosed with gingivitis. OBJECTIVE: To evaluate the efficacy of 5% TQ gel using a novel liposome drug delivery as a topical application following SRP in gingivitis patients. DESIGN: Double-blinded, parallel, randomized controlled clinical trial. SETTING: Faculty of Dentistry, King Abdulaziz University, and Qassim University, Saudi Arabia

Outcome Measures

Primary Outcomes (2)

  • Plaque index

    The measurement of the state of oral hygiene by Silness-Löe plaque index is based on recording both soft debris and mineralized deposits on the following teeth: 0 No plaque 1. A film of plaque adhering to the free gingival margin and adjacent area of the tooth. The plaque may be seen in situ only after application of disclosing solution or by using the probe on the tooth surface. 2. Moderate accumulation of soft deposit s within the gingival pocket, or the tooth and gingival margin which can be seen with the naked eye. 3. Abundance of soft matter within the gingival pocket and/or on the tooth and gingival margin.

    2 weeks

  • Papillary bleeding index

    This index permits both immediate evaluation of the patient's gingival condition and his motivation, based upon the actual bleeding tendency of the gingival papillae. A periodontal probe is inserted into the gingival sulcus at the base of the papilla on the mesial aspect, and then moved coronally to the papilla tip. This is repeated on the distal aspect of the papilla. The intensity of any bleeding is recorded as: Score 0 - no bleeding; Score 1 - A single discreet bleeding point; Score 2 - Several isolated bleeding points or a single line of blood appears; Score 3 - The interdental triangle fills with blood shortly after probing; Score 4 - Profuse bleeding occurs after probing; blood flows immediately into the marginal sulcus.

Study Arms (3)

Group I (SRP and TQ gel)

EXPERIMENTAL

In Group I patients, the lipid based TQ gel (5%) will be applied topically to the affected areas, twice daily for two weeks following SRP. The investigator performs the treatment of gingivitis based on the patient's response to therapy. For home care, the patients will be instructed to clean and dry the affected area prior to the gel application and hands will be washed prior and after its application. The patients will be instructed to not eat for 30 minutes following its application

Biological: 5% thymoquinone (TQ) gel

Group II (SRP and Placebo)

PLACEBO COMPARATOR

In Group II patients, the placebo gel will be applied topically to the affected areas, twice daily for two weeks following SRP. The investigator performs the treatment of gingivitis based on the patient's response to therapy. For home care, the patients will be instructed to clean and dry the affected area prior to the gel application and hands will be washed prior to and after its application. The patients will be instructed to not eat for 30 minutes following its application

Biological: SRP and placebo

Group III (Only SRP and one stage prophylaxis)

ACTIVE COMPARATOR

The Group III patients will be subjected to one-stage oral prophylaxis.

Procedure: Only SRP-one stage prophylaxis
