Efficacy of two commercially available dentifrices in reducing dentinal hypersensitivity

Abstract

Both the products reduced dentinal hypersensitivity in the study subjects at the end of the 12-week period. However, there was no statistically significant difference in reduction in hypersensitivity between the two products.

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

“…20,21,22 In 1884 Calvo wrote that "there is great need of medicament, which while lessening the sensibility of dentine, will not impair the vitality of the pulp". In spite of the considerable amount of research towards this objective over the past 100 years, the clinical management of hypersensitive teeth is largely empirical.…”

“…In spite of the considerable amount of research towards this objective over the past 100 years, the clinical management of hypersensitive teeth is largely empirical. 22,23,24 A survey among oral care professional's reports that dental care providers feel confident about diagnosing dentin hypersensitivity, but not about treating it. 25 It is important to note that saliva plays a role in naturally reducing dentin hypersensitivity by supplying and carrying calcium and phosphate ions into open dentin tubules to gradually bring about tubule blocking and by forming a surface protective layer consisting of presipitable aggregates of the combination of salivary glycoproteins with calcium phosphate.…”

Effect of Two Desensitizing Agents in Reducing Dentin Hypersensitivity: An in-vivo Comparative Clinical Trial

“…In general, laser therapy, preparations with fluorine, hydroxyapatite, strontium and zinc chlorides and potassium oxalate, as well as dental adhesives and glass ionomer cement are used for the treatment of dentin hypersensitivity [8,13,14]. Despite the large number of published studies, however, there is still no consensus on as to which product constitutes the "gold standard" for dentin hypersensitivity treatment [3,9].…”

“…Thus, the main approach in the treatment of dentin hypersensitivity is closing dentinal tubules by e.g. crystal precipitation in tubule lumen or hydroxyapatite melting [3]. In general, laser therapy, preparations with fluorine, hydroxyapatite, strontium and zinc chlorides and potassium oxalate, as well as dental adhesives and glass ionomer cement are used for the treatment of dentin hypersensitivity [8,13,14].…”

“…So, the development of new desensitizing agents is needed [3,8]. The search for a natural desensitizing agent with long lasting effects has led to the observation that propolis had promising effects on dentin hypersensitivity [16].…”
