             SOJ Dental and Oral Disorder  - (SOJDOD) |  Stephy Publishers ISSN 2768-6221 Introduction Dentin Hypersensitivity (DH) is a major complaint of the general population. Reports have indicated the incidence of DH is 4 to 74 percent of the population. 1  It poses a challenge for clinicians because its presentation is ambiguous with no specific signs. 2  Dentists rely on the patient’s clinical and dietary history and a thorough intraoral examination using thermal and tactile stimuli. Dentin receptors have a unique feature of eliciting pain as a response to any environmental stimulus. The sensory response in the pulp cannot differentiate between heat, touch, pressure or chemicals, because they lack specificity. Irrespective of the type of stimulus, the patient perceives any stimulus as a pain. 3  Hence careful examination should be performed to rule out other condition s which present in a similar manner to DH.

  SOJ Dental and Oral Disorder  - (SOJDOD) |  Stephy Publishers ISSN 2768-6221 Abstract Proposition: To evaluate the physical properties of flow and solubility of pure and improved mineral trioxide aggregate (MTA) cement with the addition of two plasticizing agents: sodium ether polycarboxylate and sodium naphthalene sulfonate at three different concentrations. Material and Methods: Flow and solubility tests were carried out using the established methodology recommended by the 57 ANSI/ADA and ISO 6876:2012 standards. Pure MTA was used as control group and was compared to the MTA containing sodium ether polycarboxylate and sodium naphthalene sulfonate at concentrations of 0.5%, 1.0% and 1.5%. Data were analyzed by one-way analysis of variance followed by a post-hoc Tukey test at a 5% significance level. Results: Sodium ether polycarboxylate increased the MTA flow at the three concentrations. The flow increased with increasing concentration (P<0.05). Sodium...
