Clinical Trial Summary

Will the use of Bio-smart Light Cured Protective Shield with bioactive S-PRG filler or the use of Sodium Fluoride with Xylitol-coated Calcium and Phosphate (CXP™) Varnish be able to reduce the teeth hypersensitivity similar to Sodium Fluoride Varnish?

Description:

The null hypothesis tested in this study, that there is no difference in clinical effectiveness between bio-smart Shield with bioactive S-PRG filler and Fluoride varnish containing Xylitol-coated Calcium and Phosphate (CXP™) Compared to Sodium Fluoride Varnish in management of hypersensitivity in adult patients after 1, 4 and 8 weeks.

P (Population): Patient with Teeth Hypersensitivity.

Intervention-1: Bio-smart Light Cured Protective Shield with bioactive S-PRG (Surface Pre-Reacted Glass ionomer) filler technology (PRG Barrier Coat) by (By SHOFU Inc., Japan).

Intervention-2: 5% Sodium Fluoride with Xylitol-coated Calcium and Phosphate (CXP™) Varnish (Embrace™ Varnish) by (Pulpdent Corporation)

C (Comparator): 5% Sodium Fluoride Varnish (Duraphat®) by (Colgate Palmolive Company, New York, NY)

O (Outcome):

• Primary Outcome: Pain due to Hypersensitivity

• Secondary Outcome: Mineral Content

Eligibility

Inclusion Criteria:

• Patients complaining of hypersensitive areas on facial surfaces of the teeth (incisors, cuspids, bicuspids, and first molars with exposed cervical dentin)

• Teeth scoring pain (VAS score: greater than or equal to 3) during application of stimulus (air blast and tactile sensitivity test).

• Tooth with exposed root surface, complaining from hypersensitivity (VAS score; greater than or equal to 3).

• Patients with good oral hygiene.

• Co-operative patients who show interest to participate in the study accept the 2-months follow-up period.

Exclusion Criteria:

• Patients participating in another dental study that may alter the results of this study.

• A medical condition that could hinder the accuracy of pain reporting (e.g., pain disorders).

• Any chronic medical condition that requires the regular use of anti-inflammatory pain medications.

• Patients used or applied a desensitizing varnish within the last four weeks.

• Patients with dental problems; chipped teeth, defective restorations, fractured Un-displaced cuspids or deep dental caries.

• Patients with orthodontic appliances, or bridge work that might interfere with evaluation

• Lack of patient's approval and compliance.

• Patients who are allergic to any ingredients will be used in the study.

Intervention

Other:
• PRG Barrier Coat (By SHOFU Inc., Japan)
PRG Barrier Coat (By SHOFU Inc., Japan) is a bioactive, resin-based varnish based on the proprietary Giomer concept which incorporates the patented bioactive S-PRG (Surface Pre-Reacted Glass ionomer) filler technology, where a unique combination of six beneficial ions are actively gradually released to provide a smart solution to revolutionize dentin hypersensitivity protocol
• EMBRACE™ Varnish by (Pulpdent Corporation, USA)
5% sodium fluoride with CXP™ (Xylitol-coated Calcium and Phosphate) technology for unsurpassed fluoride release and it is considered as a novel method of delivering remineralizing ions (Calcium and Phosphate) in combination with xylitol. The incorporation of CXP™ in a permeable resin matrix that does not separate, purportedly drives the sustained, time-released properties of this varnish.it has ten times more fluoride release over a 4-hour period than the leading varnish brand, in addition, it also releases bioavailable calcium and phosphate ions which are nano-coated with xylitol.
