Comparative Evaluation of the Anti-Plaque and Anti-Gingivitis Effects of Nanobiofusion Gingival Gel (NBF), Placebo Gel, and Commercial Toothpaste

14 ottobre 2026 aggiornato da: Lana Bader, King Abdullah University Hospital

Comparative Evaluation of the Anti-Plaque and Anti-Gingivitis Effects of Nanobiofusion Gingival Gel Gingival Gel (NBF), Placebo Gel, and Commercial Toothpaste: A Double-Blinded Randomized Controlled Clinical Trial

The goal of this clinical trial is to learn if Nanibiofusion Gingival Gel (NBF) is able to reduce dental plaque and gum inflammation in adults. The trial will also check whether daily use of NBF Gingival Gel causes tooth staining over time. The main questions it aims to answer are:

  • Does NBF Gingival Gel reduce dental plaque (a sticky film of bacteria on teeth)?
  • Does NBF Gingival Gel reduce gum inflammation?
  • Does NBF Gingival Gel cause tooth staining?
  • Are participants satisfied with the product's taste, texture, and ease of use?

Researchers will compare NBF gel to a placebo gel (a look-alike gel that contains no active ingredients), and Colgate toothpaste (a standard fluoride toothpaste). This will show if NBF gel is able to reduce plaque and gum inflammation.

Participants will:

  • Be assigned to one of three groups and use their assigned product twice daily for 3 months.
  • Receive a professional teeth cleaning at the start of the study, before using any product.
  • Visit the clinic at baseline and at 1, 2, and 3 months for plaque, gum health, and staining checks.
  • Receive a complimentary professional cleaning at the final visit to remove any staining.
  • Rate the product's taste, texture, and ease of use.

Panoramica dello studio

Descrizione dettagliata

Standardized Brushing Protocol:

  • All participants, regardless of group, will receive a new soft-bristled toothbrush (the same model for everyone) at the start of the study.
  • All products will be used similarly: a pea-sized amount applied to a toothbrush to brush all tooth surfaces.
  • Participants will be instructed in the Modified Bass technique to ensure consistent mechanical plaque removal.
  • To enhance compliance and technique, the first use of the product will be supervised by the clinician who will reinforce proper brushing method.
  • Participants will brush thouroughly twice daily (morning after breakfast and night before bed) for 2 minutes each time.
  • A brushing complience sheet will be given to each participant. The sheet includes a table with the study days. Each day is divided into morining and evening toothbrushing boxes. The participant nedds to tick the box where he/she brushes their teeth using the supplied product. This sheet will be checked on each follow up appointment to ensure patient's complience.

Baseline Procedures: At the baseline visit:

  1. the examiner will record the participant plaque, gingival, and staining indices. After that, each participant will undergo professional full-mouth scaling and prophylaxis immediately after examination.
  2. After cleaning, clinical intra-oral photos will be taken for all teeth all surfaces for the buccal and palatal/lingual sites (2nd molar on the right side to the 2nd molar on the left side).
  3. Participants will receive their assigned product (NBF gel, placebo gel, or toothpaste) and toothbrush, followed by supervised first-use training. The timing of subsequent follow-up will be counted from this point.

Follow-Up Schedule:

  • Participants will be followed up for 3 months, and all outcomes will be measured at baseline, 1, 2, and 3 months. Clinical intra-oral pgotos will be taken on each time point. Baseline measurements, taken before professional cleaning and product distribution, will serve as reference values.
  • The main comparative outcome measurements will be collected at the 1, 2, and 3-month visits to assess both early and sustained effects of the interventions. This extended timeline is justified because gingival inflammation and plaque accumulation can fluctuate with oral hygiene changes over weeks to months.
  • On each follow up visit, participants will be requested to bring their brushing complience sheet and assigned toothpaste. In addition, they will be asked to perform brushing in front of the examiner. This is to ensure they are using the product and brushing correctly. Un complient participants will be excluded from the study.
  • Participants will also be reminded to avoid using any oral care product other than the one provided.

Ethical considerations regarding placebo use and follow-up period:

  • Placebo participants will not be deprived of standard oral hygiene, as they will still receive full mouth scaling at baseline and professional monitoring at every visit.
  • The use of a placebo gel for 3 months is ethically justified because all participants, including the placebo group, will perform mechanical plaque control twice daily. They are still brushing.
  • Brushing is the gold standard. Mechanical removal is the primary standard of care for plaque removal.
  • The placebo group is not being deprived of treatment, but rather serves to evaluate the specific chemical efficacy of the NBF gel. Thus, participants are not exposed to harm or deviation from standard care.
  • Any participant showing early signs of carious lesion during follow up period, will be withdrawn and provided appropriate treatment.
  • Extrinsic tooth staining is a known, reversible aesthetic side effect associated with chromogenic natural extracts. To ensure non-maleficence and maintain the highest ethical standards, all participants across all groups will be offered a complimentary professional dental prophylaxis (polishing) at the final 3-month visit to safely remove any extrinsic stains acquired during the study period.

Intervento / Trattamento
Sperimentale: Nano Bio-Fusion (NBF) Gingival Gel

Participants in this group serve as the test group and will use the Nano-Bio Fusion (NBF) gingival gel, which is a toothpaste-like gel with bioadhesive properties created using nanotechnology. The gel uses nano-sized particles to improve adhesion and cellular uptake in the moist oral environment, and it is formulated with naturally derived active ingredients, including antioxidants (vitamins C and E), bee propolis, aloe vera, green tea extract, olive oil, and mastic oil.

They will apply a pea-sized amount of the gel to a standardized soft-bristled toothbrush and brush all tooth surfaces and the gumline using the Modified Bass technique. Participants are required to brush thoroughly twice daily (in the morning after breakfast and at night before bed) for 2 minutes per session over a 3-month follow-up period.

Comparatore placebo: Placebo Gel

Participants in this group serve as the placebo control to isolate the specific effects of the active ingredients. They will use a custom-formulated placebo gel developed by NanoCureTech that exactly matches the color, consistency, and flavor of the NBF gel, but lacks the active nano-bio fusion ingredients.

Comparatore attivo: Commercial fluoride toothpaste

Participants in this group serve as the positive control, representing the current standard of oral hygiene. They will use a commercial dentifrice (Colgate maximum cavity protection) that contains 1450 ppm fuoride (1.1% sodium monofluorophosphate), calicium, and arginine, along with standard toothpaste excipients. To maintain blinding, it will be dispensed in identical opaque tubes.

Cosa sta misurando lo studio?

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Plaque level using Turesky Modification of the Quigley-Hein Plaque Index (TM-QHPI) (1970).
Lasso di tempo: Baseline, 1 Month, 2 Months, and 3 Months

A disclosing agent (EMS biofilm doscloser) will be applied on all teeth and all surfaces to make the plaque visible. Clinical intra-oral photos will be taken for all teeth and all surafces (from 2nd molar on the right side to the 2nd molar on the other left side) for the buccal and palatal/lingual surfaces. The photos will be assessed by a blinded examiner to record plaque on the mesial, middle, and distal sites on both the buccal and lingual surfaces of the teeth. Each site will be given a score according to the following index:

Score Description 0 No plaque

  1. Separate flecks of plaque at the cervical (gingival) margin
  2. Thin continuous band of plaque (≤1 mm) at the cervical margin
  3. Band of plaque >1 mm wide but covering <1/3 of the crown
  4. Plaque covering ≥1/3 but <2/3 of the crown
  5. Plaque covering ≥2/3 of the crown
Baseline, 1 Month, 2 Months, and 3 Months

Misure di risultato secondarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Gingival inflammation using Löe & Silness Gingival Index (1963)
Lasso di tempo: Baseline, 1 Month, 2 Months, and 3 Months

Scores will be recorded at the mesial, middle, and distal sites on both the buccal and lingual surfaces of teeth (from 2nd molar on the right side to the 2nd molar on the left side). Each site will be scored according to the following index:

Score 0: Normal gingiva: Healthy appearance, No inflammation, No bleeding on probing Score 1: Mild inflammation: Slight change in color, Slight edema (swelling), No bleeding on probing Score 2: Moderate inflammation: Redness, Edema and glazing, Bleeding on probing present Score 3: Severe inflammation: Marked redness and edema, Ulceration, Spontaneous bleeding (may occur without probing)

Baseline, 1 Month, 2 Months, and 3 Months
Bleeding on Probing (BOP)
Lasso di tempo: Baseline, 1 Month, 2 Months, and 3 Months

This measure serves as an objective and sensitive indicator of gingival inflammation, used to complement the Gingival Index. It is assessed by gently probing the gingiva with periodontal probe and recording bleeding as present or absent. The outcome is reported as a full-mouth Bleeding on Probing percentage for each participant. The score ranges from 0% to 100%, where 0% is equivalent to completely healthy gums with no bleeding upon probing, and higher percentages indicate more widespread gingival inflammation and poorer gum health.

Baseline, 1 Month, 2 Months, and 3 Months
Teeth staining using Lang Stain Index (1981)
Lasso di tempo: Baseline, 1 Month, 2 Months, and 3 Months

Extrinsic teeth staining will be evaluated. Before the application of disclosing agent to assess plaque, clinical intra-oral photos will be taken for all teeth and all surafces (from 2nd molar on the right side to the 2nd molar on the other left side) for the buccal and palatal/lingual surfaces. The photos will be assessed by a blinded examiner to record stains on both the buccal and lingual surfaces of the teeth. Each site will be given a score according to the following index:

Score 0: No discoloration, clean and polished tooth surface, natural appearance in color Score1: Slight yellowing discoloration, yellowish film over the entire extent of the clinical crown, slight brownish discoloration along the gingival margin.

Score 2: Moderate brownish discoloration on the interproximal surfaces and in the apical third of the clinical crown.

Score 3: Heavy brown and black discoloration over the entire extent of the tooth surface, black discoloration predomina.

Baseline, 1 Month, 2 Months, and 3 Months
Patient Reported Outcome Measure (PROM)
Lasso di tempo: 1 Month, 2 Months, and 3 Months

Participants will rate the following criteria for the used product on numeric rating scale from 0 to 10:

  • Taste (0 very bad taste to 10 very good taste).
  • Texture (0 very unpleasant to 10 very pleasant).
  • Foam (0 very unpleasant to 10 very pleasant).
  • Ease of use (0 very difficult to use to 10 very easy to use).

Participants will also be asked to choose the most appropriate answer for the following questions:

  • Are you going to use the product after study completion? (will not ever use it again, might use it again, or will definitely use it again).
  • Have you noticed any teeth discoloration after using the product? (the teeth became cleaner and whiter, no change in tooth colour, teeth became more yellowish in colour).
  • Have you felt any gum pain or discomfort while using the product? (yes, no, sometimes).
  • Have you experienced any allergy after using the product? (yes, no).
  • Would you recommend using the product to family and friends? (yes, no, maybe).
