The oral cavity appears as an open ecosystem, with a dynamic balance between the entrance of microorganisms, colonization modalities, and host defenses aimed to their removal: To avoid elimination, bacteria need to adhere to either hard dental surfaces or epithelial surfaces. The oral biofilm formation and development, and the inside selection of specific microorganisms have been correlated with the most common oral pathologies, such as dental caries, periodontal disease, and peri-implantitis. The mechanical removal of the biofilm and adjunctive use of antibiotic disinfectants or various antibiotics have been the conventional methods for periodontal therapy. Ozone (O3) is a triatomic molecule, consisting of three oxygen atoms, and its application in medicine and dentistry has been indicated for the treatment of 260 different pathologies. The ozone therapy has been more beneficial than present conventional therapeutic modalities that follow a minimally invasive and conservative application to dental treatment. The exposition of molecular mechanisms of ozone further benefits practical function in dentistry. Source

From the onset of the human immunodeficiency virus (HIV) epidemic over 20 years ago (since the appearance of the first cases of contamination by the HIV virus in the 1980s), more than 60 million people have become infected and more than 20 million people have died. An estimated 15,000 new infections occur each day, with more than 95% of these in developing countries. The distinctive characteristic in the pathogenesis of HIV/acquired immunodeficiency syndrome is that the primary target cell for HIV is immune cells bearing the CD4 marker at their surface, and the CD4 cell count and viral load have been used lately as the most important laboratory parameters to evaluate the evolution of the disease. Oral lesions are common (30-80%) in patients infected by the HIV virus and may indicate an impairment in the patient's general health status and, consequently, a poor prognosis. Oral manifestations can suggest decreased cluster-differentiated (CD4+) T cell count and increased viral load, which might also aid in diagnosis, progression, and prognosis of the disease. At the tertiary level of oral care, a dentist should be available to make definitive diagnoses of oral lesions and provide professional oral services such as prophylaxis, restorations, biopsies, and the prescription of appropriate medication.

The structure and composition of the periodontium are affected in many acquired and heritable diseases, and the most significant among these is periodontal disease. Periodontal regeneration is considered to be organically promising but clinically capricious. The principal requirements for tissue engineering are the incorporation of appropriate numbers of responsive progenitor cells and the presence of bioactive levels of regulatory signals within an appropriate extracellular matrix or carrier construct. Stem cell therapy is a treatment that uses stem cells, or cells that come from stem cells, to replace or to repair a patient's cells or tissues that are damaged. And, recent progress in stem cell research and in tissue engineering promises novel prospects for tissue regeneration in dental practice in the future, with regeneration of a functional and living tooth as one of the most promising therapeutic strategies for the replacement of a diseased or damaged tooth.
