Dentine hypersensitivity (DH) is a common and harrowing dental condition. A novel BioMin‐F technology that contains 5% fluorocalcium phosphosilicate bioactive glass has been introduced. It forms fluorapatite, which is more stable towards acid erosion. There is a lack of literature with the utility of this toothpaste in treating DH. Therefore, the authors of this randomised clinical trial have aimed to compare and evaluate the efficacy of 5% fluorocalcium phosphosilicate with an 8% arginine and calcium carbonate and placebo toothpaste. A total of 75 patients clinically diagnosed with DH were randomly divided into three groups: Group A, 5% fluorocalcium phosphosilicate; Group B, 8% arginine and calcium carbonate; and Group C, placebo. The DH was evaluated by tactile and evaporative stimuli, and a visual analogue scale (VAS) was used for evaporative stimuli at pre‐baseline, baseline (15 days) and post‐baseline (1 month). The results showed symptoms of DH were reduced in all three groups. However, Group A showed a better reduction of DH than the other two groups. The toothpaste containing 5% fluorocalcium phosphosilicate was reported to be more efficacious than the other two toothpastes in managing DH. This novel development opens up a unique opportunity in the prevention and management of DH and may also be beneficial in preventing acid erosion of the tooth surface and in the maintenance of oral hygiene by reducing the effects of plaque accumulation and gingival inflammation.
Bleeding from the palatal donor site is a worrisome complication of palatal soft tissue harvesting procedures and leads to considerable stress to both the patient and the surgeon. Several methods to control palatal hemorrhage have been suggested in literature, including a palatal suture, but a precise protocol has not been suggested. The present case report aims to suggest a protocol for the greater palatine compression suture (GPCS). Five patients who experienced profuse bleeding from the palatal free gingival graft donor site were treated with the GPCS. The palatal midline was used as a landmark and the location of the greater palatine foramen was estimated. The suture was placed anterior to the estimated location of the foramen and was passed deep into the palatal tissue with the aim of looping and compressing the vascular bundle. In all the patients, an immediate reduction and arrest of bleeding from the palatal wound was observed with blanching of the soft tissues around the suture. The proposed technique is a predictable method to control palatal hemorrhage and can be used if other less invasive techniques fail to stem the blood flow from an injured palatal vessel.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
