Application of Diode Laser in the Treatment of Dentine Hypersensitivity

Abstract

Introduction:Dentine hypersensitivity is characterized by acute, sharp pain arising from the exposed dentine, most commonly in response to thermal, tactile, or chemical stimuli, and which cannot be linked to any other pathological changes in the tooth or the environment. Therapy uses various impregnating agents in the form of solutions or gels and, in more recent times, laser.Aim:The aim of this research was to examine the effects of treatment of hypersensitive dental cervix with diode laser.Materials and Methods:The study included 18 patients with 82 sensitive teeth. The degree of dentine hypersensitivity was evaluated by visual analogue scale (VAS), and the treatment was carried out by application of low-power diode laser over the span of three visits, which depended on the initial sensitivity.Results:There is a significant difference in VAS values measured at the onset of treatment (baseline) and immediately after the first laser treatment (t=9.275; p=0.000), after 7 days, after the second laser treatment (14 days) (t=7.085, p=0.000), as well as after 14 days and the third laser treatment (t=5.517, p=0.000), which confirms the effectiveness of this therapeutic procedure. The results showed a reduction of hypersensitivity in response to tactile stimulus with a probe after the third treatment, even with teeth whose value on the VAS was very high at the beginning of treatment (baseline).Conclusion:Within the scope of the conducted study, laser therapy has provided extremely safe and effective results in the treatment of cervical dentine hypersensitivity.

Evaluation of diode laser along with 1.23% acidulated phosphate fluoride gel on dentinal tubule occlusion: An in vitro study

“…[ 20 21 ] Diode lasers have been used alone as well as in combination with these agents in the management of sensitive teeth. [ 11 12 13 ] The current study tried to examine the effect of 810 nm diode laser and 1.23% APF each when used alone and in combination on dentinal tubule occlusion.…”

“…Over the past decade, the use of lasers in dentistry has become commonplace. [ 10 11 12 ] They have been used alone or in combination with an active desensitizing agent in the treatment of dentinal hypersensitivity.…”

“…Several studies have used dentinal tubule occlusion as anin vitro model to study various desensitizing treatments. [ 10 11 12 16 19 ]…”

Comparative evaluation of efficacy of diode laser and Clinpro XT varnish for treatment of dentin hypersensitivity: A randomized clinical trial

“…Incidence of DH was found more in women; in general population, it was 5%–18%, highest in periodontal patients accounting to 72%–98%, and most common in the age group 20–50 years. [ 4 5 6 ] Salivary minerals and dentinal fluids form intratubular crystals that reduce the incidence of DH. [ 7 ] Various treatment modalities exist such as desensitization of nerve endings, occlusion of dentinal tubules, and iontophoresis.…”

Effect of the casein phosphopeptide-amorphous calcium phosphate fluoride (CPP-ACPF) and photobiomodulation (PBM) on dental hypersensitivity: A randomized controlled clinical trial

“…PBM increases the production of mitochondrial adenosine triphosphate (ATP) and the presence of β-endorphin suppressing P substance activity, it also decelerates the action potential velocity of C and Aδ fibers decreasing pain [14]. Also, PBM increases the odontoblasts tertiary dentin production obliterating dentinal tubules and reducing DH [15].…”
