Oral tissue regeneration has received growing attention for improving the quality of life of patients. Regeneration of oral tissues such as alveolar bone and widely defected bone has been extensively investigated, including regenerative treatment of oral tissues using therapeutic cells and growth factors. Additionally, small-molecule drugs that promote bone formation have been identified and tested as new regenerative treatment. However, treatments need to progress to realize successful regeneration of oral functions. In this review, we describe recent progress in development of regenerative treatment of oral tissues. In particular, we focus on cyclodextrin (CD)-based pharmaceutics and polyelectrolyte complexation of growth factors to enhance their solubility, stability, and bioactivity. CDs can encapsulate hydrophobic small-molecule drugs into their cavities, resulting in inclusion complexes. The inclusion complexation of osteoinductive small-molecule drugs improves solubility of the drugs in aqueous solutions and increases in vitro osteogenic differentiation efficiency. Additionally, various anionic polymers such as heparin and its mimetic polymers have been developed to improve stability and bioactivity of growth factors. These polymers protect growth factors from deactivation and degradation by complex formation through electrostatic interaction, leading to potentiation of bone formation ability. These approaches using an inclusion complex and polyelectrolyte complexes have great potential in the regeneration of oral tissues.

AbstractOver the last years, interest in intranasal administration as an alternative and promising route for the delivery of drugs withlocal, systemic, and even central nervous system action has tremendously increased. Accordingly, understanding of the propertiesand characteristics of the nasal cavity as well as the biodisposition processes of drugs into the nasal compartments is acquiringa significant prominence in the field of pharmacology. In this context, the development and validation of bioanalytical methodologies for the quantitative measurement of drugs and their metabolites in nasal and paranasal tissues and/or secretions is of the utmostimportance. However, currently, information concerning bioanalysis of drugs in nasal and paranasal tissues and/or secretionsis scattered. This review aims to provide a valuable overview of the methodologies that have been used for the collectionand preparation of nasal and paranasal samples with special emphasis placed on the review of liquid chromatographic methodsemployed for the quantitative determination of small-molecule drugs and their metabolites in such specimens.
