Protocol summary

Study aim
Determine the 6-month effect of Er: Cr: YSGG laser and several dentinal sensitisers in the treatment of dentinal hypersensitivity
Design
Clinical trials, with parallel, double blind, randomized groups. 175 dentin hypersensitivity teeth will be divided into 5 groups based on the treatment protocol and the results will be compared.
Settings and conduct
Location: Hamadan University of Medical Sciences Method: First, the participants will be assigned to the groups according to their initial sensitivity. After randomization, the teeth will randomly be divided into five groups based on the received treatment. Patients will be followed after 1 week, 1 month and 6 months after treatment. At each appointment, the evaluation process will be repeated for each patient and the patient's VAS score will be recorded. Finally, the scores obtained from the patients in each group will be statistically analyzed.
Participants/Inclusion and exclusion criteria
Inclusion criteria: Good general health; without decay or restoration; without previous treatment; Age and mental ability to determine pain score; No history of bleaching. Non-inclusion criteria:People with chronic diseases; People who have used toothpaste or desensitiser mouthwash for the past 3 months; People who have had periodontal surgeries in the last 6 months;non vital teeth or vital teeth that have cracks, previous repairs, decay lesions or active periodontal disease; People with deep caries in the vicinity of a sensitive tooth
Intervention groups
Intervention group1: Er: Cr: YSGG laser expose to the sensitive teeth. Intervention group2: varnish fluoride will rub to the sensitive teeth. Intervention group3: first varnish rub on the sensitive teeth, and then laser will be exposed. Intervention group4: gluma will rub on the sensitive teeth. Intervention group5: first gluma rubbed on the sensitive teeth, and then laser will be exposed.
Main outcome variables
tooth sensivity

Inclusion/Exclusion criteria
Inclusion criteria:
Good general health without any known allergies to commercial dental products The teeth do not have any decay or restoration The patient has not previously received any treatment for dentin hypersensitivity The patient has the ability to determine the pain score in the VAS in terms of age and mentality Patients do not have a history of receiving bleaching treatments
Exclusion criteria:
People with chronic disease with daily episodes of pain that use analgesics, antihistamines, anti-inflammatory drugs, or analgesics during the last 72 hours People who have used toothpaste or antisensivity mouthwash for the last 3 months. People who have had periodontal surgeries in the last 6 months. non vital teeth or vital teeth with crack, previous restoration, decay lesions, or active periodontal disease. patients without active periodontal disease will remain active in the study People with deep carries adjacent to a sensitive tooth that have a chance of confusing pain with sensitive tooth pain

Sample size
Target sample size: 35
More than 1 sample in each individual
Number of samples in each individual: 5
The teeth with dentin hypersensitivity that can vary from one tooth to all teeth and in the above box, an average of 5 teeth were mentioned
Randomization (investigator's opinion)
Randomized
Randomization description
At first, participants are classified according to their initial sensitivity and then randomly divided into random classes in a randomized block to ensure that each group is in the same state of origin in terms of initial sensitivity. Block size and randomization method will be determined by another person Other than the therapists and evaluators. Given the fact that the stimulus air flow is effective in evaluating the effectiveness of the therapeutic methods compared to the adjacent teeth, only one treatment will be used in each jaw quadrant.
Blinding (investigator's opinion)
Double blinded
Blinding description
This study is a double-blind study. One operator irradiate laser and apply densitisers , while the other operator will assess the sensitivity. Also, patients will not be aware of the treatment they will receive and on the teeth Patients whose therapeutic protocol does not include lasers will be targeted by the aiming beam.

Intervention groups

1

Description
Intervention group 1:laser: Laser Er, Cr: YSGG (Waterlase, Biolase Technology, Irvine, CA) perpendicular to the dentin surface by moving scanning movements at a distance of 1 mm with zero percent of air and water for 30 seconds with a frequency of 20 Hz and a power of 0.25 W (44.3J / cm2) whit M Z6 sapphire tip with a diameter of 600 micron and a length of 6 mm will be exposed on the sensitive teeth.
Category
Treatment - Devices

2

Description
Intervention group 2 (fluoride varnish):A cotton roll for isolating the environment and preventing the varnish mix with saliva will be used. Then, a thin layer of Fluoride varnish (Ivoclar Vivadent), will be applied on the surface of the tooth with a disposable microbrush in accordance with the factory's instructions. Two to three layers of varnish will be applied to the surface of the teeth on the same day. Patients will be told to stop taking any food or carbonate drink for an hour after using varnish.
Category
Treatment - Drugs

3

Description
Intervention group 3 (fluoride varnish and laser): The varnish will be used similarly to the method used in group 2 on the teeth surface, and the varnish will remain in place for 60 seconds, and then the laser will be exposed with the same radiant profile of the group 1 on its surface.
Category
Treatment - Drugs

4

Description
Intervention group 4 (Gluma): A cotton roll for rubbing the Gluma (Heraeus Kulzer GmbH, Hanau, Germany) will be used with a gentle but firm motion on the tooth surface. After 30 to 60 seconds, the dentin will dry completely until The fluid will disappear and the surface will lose its gloss state.
Category
Treatment - Drugs

5

Description
Intervention group 5 (Gluma and laser): The Gluma will be used similar to that used in group 4 on the teeth surface. then, the laser will be exposed with the same radiant profile of the group 1 on its surface.
