Unit Description

The General Odontology and Specialties has as main objective to develop treatments, models, and material to improve oral health. The Unit’s strategic plan continuously seeks the international presence through collaboration projects with international institutions, and with established research centers as well, not leaving behind academic collaboration with national institutions and research programs with local and national industries to improve potential antiseptic products.

  • Molecular Detection in microorganisms via clinic real-time PCR and qPCR genic expression analysis of microorganisms.
  • Quorum Sensing and gene expression in natural germ habitat virulence.
  • Development and assistance to projects of microbial biochemistry, biotechnology, and microbial regulation processes in bioreactors areas.
  • Obtainment and identification of compounds of interest for the agri-food and health sectors.
  • Identification, extraction, and accumulation of bacteriocin produced in lactic acid bacteria metabolism (probiotics)
  • Relevant molecule identification stemming from natural extracts and/or use of organic residues of industrial processing.
  • Study of the antimicrobial, antifungal, bactericide and/or antibiotic effectivity and viability of relevant substances. Supported evidence by norms NMX-BB-040-SCFI-1999, CSL 27 No. 1, 2007 and Kirby Bauer methods 1966, Andrews JM 1991.
  • Natural product identification and its use in dental therapies.
  • Molecules derived from plant identification and its application on dental materials and its industrial use.
  • Epidemiologic studies of oral microbiomes.
  • Analgesic use of medicinal plants.
  • Epidemiologic studies of oral cancer.
