An In-Vivo Comparative Study of the Efficacy of Propolis, Nano-Hydroxyapatite and Potassium Nitrate Containing Desensitizing Agents.

Abstract

Dentin hypersensitivity is an oft encountered dental complaint, the management of which has evolved incredibly but remains an enigma.Nano-hydroxyapatite (n-HAp) is considered one of the most biocompatible and bioactive materials, and has gained wide acceptance in medicine and dentistry in recent years. An increasing number of reports have shown that nano-hydroxyapatite has the potential to remineralize artificial carious lesions following addition to toothpastes, mouthwashes, etc. Recently, occlusion of exposed dentinal tubules by nano-hydroxyapatite, helping to reduce hypersensitivity, has been reported. Propolis, a natural, non-toxic resin produced by honey bees has also been reported to partially obliterate dentinal tubules and can be a good modality of treatment for hypersensitivity. Hence, the aim of this clinical trial is to compare the efficacy of propolis and nanohydroxyapatite dentifrice with benchmark potassium nitrate in controlling dentin hypersensitivity. Forty five patients with a complain of dentin hypersensitivity were recruited. Baseline examination was conducted using tactile and cold stimuli. Patients were randomly divided into three groups.(n=15) Grp I: Potassium nitrate desensitizing agent Grp II: Nanohydroxyapatite desensitizing agent Grp III: Propolis containing agent A visual analog scale was used to evaluate participants’ pain at baseline, one week, and four weeks after the usage of the dentifrices. According to paired t test, all the three desensitizing agents had a significant reduction in the dentin hypersensitivity (p<0.01). According to one way ANOVA, the sensitivity scores were significantly lower in the group II in comparison with group I (p=0.03). However the difference between group I and group III, as well as group II and group III were not significant i.e. p=0.63 , p=0.21 respectively. Within the limitations of the study, it can be concluded that nanohydroxyapatite and propolis are a potential treatment modality for dentin hypersensitivity. Clinical significance: Nano-hydroxyapatite and propolis have proved to be a biocompatible and natural alternative for the treatment of dentin hypersensitivity, respectively.
