Abstract

The administration of local anesthetics (LA) in Dentistry still causes pain and stress, being often the reason for patients to leave treatment, with serious consequences for their oral health. Topical anesthetics were developed to minimize pain sensation caused by needle insertion and injection. However, the commercially available formulations usually show low efficiency, and little scientific progress has been achieved in the development of topical anesthetics able to eliminate any inherent local anesthesia painful sensation. This project aims the development of a sustained release system for the delivery of lidocaine and prilocaine in nanostructured lipid carriers (NLC) in chitosan and pectin biopolymers matrices, processed as a bioadhesive and a hydrogel, for topical anesthesia of the oral mucosa. Such drug-delivery system should have higher efficiency and lower toxicity, in order to fulfill this gap in Dentistry anesthesia. The characterization of beads containing LA will be carried out by: infrared spectroscopy (IR), thermal (TG/DSC) analyses, scanning electron microscopy (FE-SEM, TEM), Zeta potential, particle size distribution and polidispersity, measured by dynamic light scatter (DLS) and nanoparticle tracking analysis (NTA). The characterization of hydrogels and bioadhesives will be conducted by mechanical studies, mucoadhesiveness assays. Moreover, in vitro drug release, dissolution and permeation across the pig oral mucosa in Franz type diffusion cells will be conducted.
