Cyanoacrylate and Laser and Dentin Sensitivity (Cyano-laser)

August 13, 2020 updated by: Olga Flecha, Federal University of São Paulo

Effectiveness of Cyanoacrylate and Laser in the Treatment of Cervical Dentin Sensitivity

This study aimed to evaluate the effectiveness of two treatments for dental hypersensitivity: cyanoacrylate (Super Bonder®) compared with use of low intensity laser treatment (LILT). As the cyanoacrylate is a lower cost treatment, the hypothesis in investigation is if this product is equally effective as the laser treatment.

Detailed Description

The present study included 62 patients (15 male and 47 females, aged 12 to 60 years). The initial cervical dentin hypersensitivity was checked throughout a thermal test (air blast). The 434 teeth included were that with a score ≥5 in a numerical scale rating of pain. Teeth were randomly assigned according quadrants (split mouth design) - 216 were allocated to LILT group and 218 for the Super Bonder® group. Thermal tests with a tetrafluoroethane spray (Endo-Ice®) and air blast were performed and considered as baseline. Pain parameters were recorded using a numerical scale rating with 24 hours, 30, 90 and 180 days after the interventions. Quality of life of the patients was also assessed with the use of OHIP-14 at baseline and after 180 days.

  • Interventional Model: Parallel Assignment
  • Masking: Triple

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Cyanoacrylate
3 applications of cyanoacrylate (48 hours interval)at the cervical region of the sensitive tooth
3 applications of cyanoacrylate (48 hours interval) at the cervical region of the sensitive tooth
Other Names:
  • Superbonder
Active Comparator: Laser
3 Low intensity laser application (48 hour interval). The application of 1Joule/cm^2 was performed for eight seconds at three points along the dental neck, using the infrared wavelength (795nm)
This process was conducted three times with an interval of 48 hours between applications, according to laser's manufacturer advice Clean Line Easy Laser - LILT®, Clean Line Easy Laser Doctor Dental Products Industry LTDA, BRA). For dentin hypersensitivity, the application of 1Joule/cm^2 is recommended for eight seconds at three points along the dental neck, using the infrared wavelength (795nm).

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change of the Pain Sensitivity
Time Frame: Baseline and 180 days
Change in pain experienced by the participants was calculated as the difference between baseline level of pain sensitivity and after 180 days. Pain was recorded using a numerical pain assessment scale with range between 0 (no pain) to 10 (worst possible pain). The higher the numbering the worse the result.
Baseline and 180 days

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Quality of Life Improvement
Time Frame: Baseline and 180 days
Difference between the level of quality of life - Oral Health Impact Profile "OHIP" at baseline and 180 days. OHIP-14 total scale ranges from 0 to 56 points with higher scores indicating a poorer oral health-related quality of life. The response format uses a Likert-type frequency scale such as follows: very often = 4, fairly often = 3, occasionally = 2, hardly ever = 1, never = 0. Total score is obtained by summing the response codes of the 14 items constituting the measure.
