Comparative Evaluation of Immediate Efficacy of Diode Laser Versus Desensitizing Paste Containing 8% Arginine and Calcium Carbonate in Treatment of Dentine Hypersensitivity: An in Vivo Study

Abstract

BACKGROUND & OBJECTIVES:The aim of the study was to evaluate the immediate efficacy of diode laser versus desensitizing paste containing 8% arginine and calcium carbonate in the treatment of dentine hypersensitivity. METHODOLOGY: 50 patients with complain of tooth hypersensitivity were randomly selected for an 8 week clinical trial with the set inclusion and exclusion criteria. Each patient was assigned to one of the two study groups: Group 1 (n=25) -8% arginine and calcium carbonate paste (Pro-Relief paste, Colgate-Palmolive Ltd, India) and Group 2 (n=25) -Diode laser(AMD, Picasso Diode, Indianapolis, Indiana), who received a baseline evaluation of tactile hypersensitivity with the help of dental explorer and an air blast hypersensitivity. The effectiveness of the therapy was assessed by VAS Scale of 10, along with the hard and soft tissue evaluation, at 4 examination periods: 1) immediately after the application of the diode laser 2) after 15 days 3) after 4 weeks & 4) after 8 weeks. RESULTS: 8% arginine and calcium carbonate showed significant results (67.27%) than diode laser (56.55%) at immediate and 4 weeks evaluation by mechanical stimulus and immediate evaluation by air stimulus. Diode laser showed highly significant results in progressive decrease in the dentin hypersensitivity till 8 weeks whereas 8% arginine showed highly significant results till 4 weeks. CONCLUSION: The immediate efficacy of 8% arginine and calcium carbonate (Colgate Pro Relief) was higher as compared to diode laser. Diode laser showed progressive reduction till 8 weeks whereas Colgate Pro Relief showed progressive reduction only till 4 weeks.

Evaluation of the Occluding Characteristics of Nanosized Eggshell/Titanium Dioxide with or without Saliva

“…This may; however, be attributed to the treatment duration (►Table 2). As reported in literature, 12 the occluding capabilities of saliva occur gradually within a long time. In support of the role saliva plays in reducing DH, the dentine tubules occlusion observed for Sensodyne repair showed an outstanding occlusion when compared against the samples treated without saliva.…”

“…However, the hydrodynamic theory expanded upon by Brannstrom is now accepted by the dental community as the most likely mechanism for DH occurrence. 12 In an attempt to control this process, products or agents that typically aimed to reduce fluid flow, and or interfere with the nerve impulses have been reported in the literature. 11,13 At the first line of at-home therapy for DH management, the use of occluding agents is often recommended for effective treatment.…”

“…11,13 At the first line of at-home therapy for DH management, the use of occluding agents is often recommended for effective treatment. 14 Several different occluding agents such as potassium oxalates, 15 sodium fluoride and sodium monofluorophosphate, 12 strontium salt, 16 amorphous calcium phosphate containing casein phosphopeptide, 17 and calcium glycerophosphate 18 have been widely utilized in desensitizing paste for their dentine tubule occluding capabilities. Still, the effectiveness of the aforementioned occluding agents will depend on the flow of saliva.…”

The Application of the Logistic Equation Model to Predict the Remineralization Characteristics of Desensitizing Paste

“…Although bioactive glass occludes patent dentinal tubules by supplying calcium (Ca 2+ ) and phosphate (PO 4 3− ) ions in an optimum oral environment to form hydroxycarbonate apatite (HCA) [7, 8], in some patients, however, particularly those with conditions of hyposalivation and xerostomia, the flow of saliva is limited [9]. As reported in the literature [10, 11], saliva facilitates the deposition of the trap Ca 2+ and PO 4 3− ions into open dentine tubules that gradually bring about tubule sealing or occlusion. Hence, it is sufficient to assume that the effectiveness of the bioactive glass will be less effective in patients with a limited flow of saliva.…”
