Abstract
The present study aimed to assess dentin hypersensitivity (DH) level and quality of life in patients before and after treatment with ozonated oil compared with extra virgin oil. This is a randomized triple-blind controlled clinical trial, consisting of patients with dentin hypersensitivity which was stimulated by evaporative and thermal stimuli. DH level was measured using a numerical rating scale. The patients were treated with ozonated oil and olive oil. Data were measured at baseline, immediately, and 4 weeks after treatment. The Dentine Hypersensitivity Experience Questionnaire (DHEQ-15) and the Oral Health Impact Profile (OHIP-14) were applied at baseline and 4 weeks after treatment. The sample consisted of 8 women and 3 men, with an average age of 23.82 years. The test group was 40 teeth while the control group consisted of 36 teeth, with the most prevalent tooth being the incisor (52.6%). There was a significant reduction in the DH level and an improvement in the quality of life after treatment. Among the sample, 90.1% reported an improvement in the final result. Both ozonated oil and olive oil were effective in reducing dentin hypersensitivity level and improving oral health-related quality of life 30 days after treatment.
Highlights
Dentin hypersensitivity (DH) is characterized as an acute and brief pain when dentin is exposed to thermal, evaporative, tactile, osmotic, or chemical stimuli and cannot be attributed to any form of dental defect or pathology (Canadian Advisory Board on Dentin Hypersensitivity, 2003; Cunha-Cruz, et al, 2011)
The objective of this work was to compare the effectiveness of ozonated oil with extra virgin oil in reducing the DH level
There was a statistically significant difference for DH level stimulated by air jet for test treatment (p = 0.001) after 30 days
Summary
Dentin hypersensitivity (DH) is characterized as an acute and brief pain when dentin is exposed to thermal, evaporative, tactile, osmotic, or chemical stimuli and cannot be attributed to any form of dental defect or pathology (Canadian Advisory Board on Dentin Hypersensitivity, 2003; Cunha-Cruz, et al, 2011). With the increase of hydrodynamic stimuli inside the tubules, the nociceptives are activated, causing the characteristic pain (Brännström & Garberoglio, 1980; Moretzsohn & Campos, 2001). The prevalence varies in different studies, in which it is reported that DH occurs more in adults, being more common in people between 20 and 40 years old, with a peak of greater occurrence at the end of the third decade (Vale & Bramante, 1997). Population studies indicate that this type of painful manifestation affects one in seven adult patients and can result in behavioral and emotional changes (Grippo, 1991; Vale & Bramante, 1997; Moretzsohn & Campos, 2001; Sgolastra, et al, 2011)
