A comparative evaluation of the effect of four desensitizing agents (strontium chloride, potassium nitrate, pro-argin, bioactive glass) on dentinal occlusion: An ex-vivo SEM study

AbstractDentinal hypersensitivity (DH) is a painful clinical condition and is characterized by pain arising from exposed dentin in response to various stimuli. Various treatment modalities are available to treat dentinal hypersensitivity which include at-home and in-office treatment. At home treatment generally consists of a variety of dentrifices containing different constituents like stannous fluoride, strontium chloride and potassium oxalate. These agents cause occlusion of dentinal tubules which decreases both dentine permeability and fluid movement thereby reducing hypersensitivity. Recently, bioactive glass (NovaMin) has been incorporated as a remineralising ingredient in dentifrice formulations for treating Dentinal Hyprsensitivity. It relieves the symptoms by precipitating hydroxycarbonate apatite (HCA) onto the tooth surface. Another combination product consisting of an aqueous solution of 5% glutaraldehyde and 35% hydroxyethyl methacrylate (Gluma desensitizer) has also been reported to be an effective desensitizing agent. Thus, the aim of the study was to evaluate and compare the tubule occluding effect of of two desensitizing agents, which are bioactive glass (Novamin), and Gluma Desensitizer. In the present study bioactive glass was found to produce more completely occluded tubules while Gluma desensitizer caused more partial occlusion on initial application. Hence, NovaMin application could be more effective in providing relief from dentinal hypersensitivity when compared with Gluma Desensitizer.

Background : Dentinal hypersensitivity (DH) is a painful clinical condition and is characterized by pain arising from exposed dentin in response to various stimuli. Various treatment modalities are available to treat dentinal hypersensitivity which include at-home and in-office treatment. At home treatment generally consists of a variety of dentrifices containing different constituents like strontium chloride and bioactive glass (Novamin). These agents cause occlusion of dentinal tubules thereby reducing hypersensitivity.Purpose: This study was to evaluate the effects of different desensitizing dentifrices on dentinal tubule occlusion by scanning electron microscopy (SEM) of strontium chloride and bioactive glass (Novamin) pastes in the treatment of dentinehypersensitivity (DH) Methods: sixteen extractedspecimens from bovine incisors teeth with randomized into 2 groups (n=8). The crowns were removed from the root and the crown were sectioned longitudinally into two parts (in a mesiodistaldirection). The cervical toothwere resulting in two samples per tooth.Dentinal tubules were exposedand thesamples provided a 4 mm x 4 mm area of exposed dentinal tubules.Group 1 (treated with strontium chloride), Group 2 (treated with bioactive glass (novamin))After each treatment for seven days, tubule occlusion on dentin were analyzed by scanning electron microscopy (SEM).The data were analyzed using “mann-whitneytest” (p<0.05).Result: Groups bioactive glass (novamin) showed tubule occlusion highest when compared with groups strontium chloride.Conclusion: bioactive glass (novamin) paste showed tubule occlusion highest with strontium chloride

Tubule Occlusion

Introduction: Dentine hypersensitivity (DH) occurs on exposed dentine and is dependent on the patency of dentinal tubules. This study compared the effectiveness of toothpaste containing Strontium Chloride, Novamine, Pro-Arginine in occluding dentine tubules along with comparision of those. Materials and Method: 45 freshly extracted teeth were randomly divided (15 each) into 3 groups: Group 1 15 Teeth treated with toothpaste containing Strontium Chloride. Group 2 15 Teeth treated with toothpaste containing Novamine Group 3 15 Teeth treated with toothpaste containing Pro-Arginine. Each specimen was brushed with the dentifrice slurries and examined under SCM. Result: The mean of occluded dentinal tubules on the dentin surface after brushing with three dentifrices were significant among them Pro-arginine group showed maximum occlusion. Conclusion: The present in vitro SEM study results revealed that: All the experimental agents– Strontium chloride, novamin, Pro- Argenine were effective in occluding dentinal tubules & the percentage (%) of occluded tubules was found to be highest for Pro- Argenine as compared to the other groups.

Cleaning Efficacy

ABSTRACT Objectives The present study was conducted to compare the cleaning efficacy (debris and smear layer removal) of hand and two NiTi rotary instrumentation systems (K3 and ProTaper). Materials and methods Sixty single rooted human maxillary anterior teeth decoronated at the cementoenamel junction were used. All the specimens were divided into four groups of 15 teeth each, group I—ProTaper rotary instrumentation done, group II—K3 rotary instrumentation done, group III—Stainless steel K-file instrumentation done, group IV—root canal irrigation without instrumentation. Root canal preparation was done in a crown down manner and 3% sodium hypochlorite was used as irrigant after each file followed by final rinse with 5 ml of 17% EDTA solution, then specimens were scanning electron microscopic (SEM) examination. Results Statistical analysis was done using one-way ANOVA followed by post hoc Tukey's HSD test. Group I showed highly statistical significant difference compared to other groups. There was no statistically significant difference considering smear layer at any levels among the groups with no smear layer formation in group IV. Conclusion ProTaper rotary instrumentation showed the maximum cleaning efficacy followed by K3 rotary instrumentation in the coronal, middle and apical thirds of the root canal. Clinical significance ProTaper rotary instruments are more efficient than hand and K3 rotary instruments during root canal treatment.
