“…Literature suggested that for DH to be initiated, the dentinal tubule must be exposed to the external environment, which is caused by the removal of the protective smear layer covering the tubule. Notably, SEM studies have shown that tubules in exfoliated teeth (sensitive tooth) are eight times more numerous, twice larger in diameter and are open, whereas tubules in non-sensitive tooth are less numerous, smaller, and usually blocked [8,20,21].…”

Dentin hypersensitivity [DH] associated with short sharp pain is a public health concern with a dire consequence to good oral health hygiene. Although different materials and desensitizing toothpastes have flooded the market with claim to provide relief for DH patients by occluding patent dentinal tubules, their occluding abilities have been limited. As such, a new strategy it’s required to effectively manage DH. The use of nanomaterial for dentinal tubules occlusion is predicted to revolutionize the treatment of DH. This article aimed to review the effectiveness of nanomaterials in the management of DH.

“…7 The aforementioned theory is widely supported by scanning electron microscope (SEM) evidence, which revealed that dentinal tubules in the sensitive tooth are eight times more numerous, twice larger in diameter and are open, whereas tubules in the non-sensitive tooth are less numerous, smaller, and usually blocked. [8][9][10] Thus, and as reported by Yu et al, 11 the ideal strategy in the management of DH would be to effectively occlude the dentinal tubules to prevent fluid flow.…”

Objectives: Dentin hypersensitivity (DH) is a notable painful condition with a negative impact on quality of life. This paper evaluates the occluding abilities of nanohydroxyapatite synthesized from the eggshell waste (EnHAp) in the treatment of DH. Methods: EnHAp was synthesized following the wet chemical precipitation method. The purity and phase change were characterized using Fourier transform infrared (FTIR) and X-ray diffraction (XRD). Field emission scanning electron microscopy (FESEM) and high-resolution transmission electron microscopy (HRTEM) were used to observe the morphology of EnHAp. The occluding capabilities were evaluated in vitro using the bovine model. Twenty-five simulated dentin specimens were randomly assigned to five groups: Group 1, untreated; Group 2, eggshell powder alone; Group 3, calcined eggshell powder; Group 4, Colgate Sensitive treated, EnHAp; and Group 5, calcium dihydrogen phosphate (n = 5). The specimens were then subjected to remineralization protocol. The tubule occluding capabilities were observed using FESEM. Analysis of variance was used to analyze the occluding ratio values for all treated specimens. Post hoc test with Bonferroni correction was used to identify the mean differences among the five test groups (α = .05). Results: The FTIR and XRD results confirm that synthesis of EnHAp occurred. HRTEM and FESEM revealed an irregular rod structure with a particle size of 65 nm. The occluding area ratios observed for the EnHAp specimens were significantly higher than other test groups (p < 0.001). Conclusions: The application of EnHAp resulted in an efficient occlusion of dentin tubule. This study suggests that EnHAp is an effective therapy to treat DH.

Context: Dentinal hypersensitivity is an exaggerated response to nonnoxious sensory stimuli which is viewed by individuals as an important health problem. Recently, a growing interest in herbal-based products is found to be beneficial as the conventionally based formulated product. Aims: The aim of the study was to evaluate and compare the dentinal tubule occlusion ability of herbal desensitizing toothpaste and mouthwash on extracted teeth using scanning electron microscopy (SEM) analysis. Settings and Design: This was a nonclinical, prospective study. Subjects and Methods: This study was done on 45 dentinal samples obtained from human-extracted teeth. Forty-five dentin samples were prepared, sectioned mesiodistally, etched with 6% citric acid for 2 min, washed with distilled water, and divided into: Group 1: specimens were placed in distilled water (control group) for 14 days, Group 2: specimens were brushed 2 min twice daily with HiOra-K™ toothpaste for 14 days, and Group 3: specimens were rinsed 2 min twice daily with HiOra-K™ mouthwash for 14 days. At the end of 3, 7, and 14 days, specimens were subjected to SEM analysis to detect tubular occlusion. Statistical Analysis Used: Chi-square analysis and analysis of variance were used for the significance study parameters on categorical scale and between groups (intergroup analysis) on metric parameters. Results: Toothpaste yielded better results of complete occlusion of dentinal tubules when compared with mouthwash at the end of 3, 7, and 14 days. Conclusions: Herbal desensitizing toothpaste and mouthwash occluded the dentinal tubules and are found to be effective in the management of dentinal hypersensitivity. CLINICAL RELEVANCE TO INTERDISCIPLINARY DENTISTRY Dentin hypersensitivity is a persistent clinical problem that poses significant challenge for clinicians and the patients.This study has evaluated a treatment modality for dentinal hypersensitivity using Herbal products. With the resolution of dentinal hypersensitivity it will be beneficial to the society and improve the patient's quality of life.
