Comparison of Dentin Hypersensitivity Reduction Over a 1-month Period

Here we assessed the clinical effectiveness of Gluma, fluoride varnish, and the Tetric N-Bond one-step self-etch system in alleviating DH instantly and over 1 month, after a single topical application.A randomized, double-blind, clinical trial was conducted on 55 patients (25 males, 30 females; age: 20-49 years). Seventy teeth were randomly assigned to three groups: Gluma (n = 24); fluoride varnish (n = 23); and Tetric N-Bond adhesive (n = 23). Sensitivity to tactile, air blast, and cold stimuli were investigated.. A visual analogue scale was used to assess tactile stimuli, and the Schiff Cold Scale to assess air blast and cold stimuli. DH was evaluated immediately post-treatment, and at the 2-week and 1-month follow-up. Between-group and within-group comparisons were made.

Inclusion criteria

  • Middle-aged adult population who usually complains of Dentin Hypersensitivity.
  • Age range 20-49 years, that visit the dental hospital at King Abdul-Aziz university (KAUDH) who would have at least one or two teeth with DH
  • Those with recession of the gingiva, teeth erosion or abrasion.
  • Patients agreed to participate in the study.

Exclusion criteria

  • Chronic; far on progress periodontal disease; treatment for periodontal disease;
  • Teeth with ICDAS (International Caries Detection and Assessment System) score 4
  • Teeth diagnosed for irreversible pulpitis; root canal treated teeth
  • Teeth covered with crowns; bridge

  • Medically compromised patients currently using medications like anticonvulsants, antihistamines, antidepressants, sedatives or daily analgesics.
  • Pregnant or lactating women; were also excluded.

Treatment and study plan

Gluma

Other

Gluma is desensitizing agent by (Heraeus Kulzer, Armonk, NY, USA) claimed to treat dentine hypersensitivity in exposed cervical teeth surfaces and was applied to participants using a mini brush applicator tip onto the exposed hypersensitive tooth surface requiring treatment and was allowed to dry for 60 seconds. Then Dentine hypersensitivity (DH) was assessed for tactile, cold, and air blast stimuli immediately after completion of treatment. Subjects were also recalled for re-evaluation at 2 weeks and at 1 month after desensitizing treatment.

fluoride varnish

Other

fluoride varnish is usually applied to patients to prevent caries development but was claimed in some cases to also relief dentine hypersensitivity and was applied as a thin layer to the surface of the tooth using an applicator. The varnish set rapidly, and thereafter moisture contamination was not a concern. Patients were advised to not brush or floss their teeth for a couple of hours and to abstain from hot beverages. DH was assessed for tactile, cold, and air blast stimuli immediately after completion of treatment. Subjects were also recalled for re-evaluation at 2 weeks and at 1 month after desensitizing treatment.

Tetric N-Bond self-etch adhesive

Other

Tetric N-Bond self-etch adhesive is one step dental adhesive and is also claimed to relief dentine hypersensitivity due to blockage of dentinal tubules. It was applied according to the manufacturer's instructions, in a thick layer, for at least 30 seconds, using a light brushing motion. Then, it was dried with a steady stream of air for 3 seconds and light-cured for 10 seconds. DH was assessed for tactile, cold, and air blast stimuli immediately after completion of treatment. Subjects were also recalled for re-evaluation at 2 weeks and at 1 month after desensitizing treatment.

Primary outcomes

  1. Assess dentine hypersensitivity score to stimuli at Baseline

    Time frame: Baseline before treatment

    Scores of DH for tactile stimulus were recorded using visual analogue scale and for cold, and air blast stimuli using the Schiff Cold Air Sensitivity Scale 18 at baseline.

  2. Assess dentine hypersensitivity score to stimuli immediately after treatment by intervention

    Time frame: From baseline to immediately after treatment with intervention

    Scores of DH for tactile stimulus were recorded using visual analogue scale and for cold, and air blast stimuli using the Schiff Cold Air Sensitivity Scale 18 were recorded immediately after treatment with intervention and compared score to baseline.

  3. Assess dentine hypersensitivity to stimuli at two-weeks follow up after treatment by intervention

    Time frame: From baseline to two-weeks follow up after treatment with intervention

    Scores of DH for tactile stimulus were recorded using visual analogue scale and for cold, and air blast stimuli using the Schiff Cold Air Sensitivity Scale 18 were recorded at two-weeks follow up after treatment with intervention and compared score to baseline and immediate treatment scores.

  4. Assess dentine hypersensitivity to stimuli at one month follow up after treatment by intervention

    Time frame: From baseline to one month follow up after treatment with intervention

    Scores of DH for tactile stimulus were recorded using visual analogue scale and for cold, and air blast stimuli using the Schiff Cold Air Sensitivity Scale 18 were recorded at one month (30 days) follow up after treatment with intervention and compared score to baseline and immediate treatment, and two weeks follow up visit scores.
