The Bio-Molecular Dynamics of Dental Pulp in Different Clinical Scenarios

Dental pulp (DP) is a very dynamic tissue both in health and in disease. When exposed to stressors and pathological conditions. It undergoes a complex series of biological reactions whereby alterations affect the pulp tissue at tissue cellular and molecular levels. The aim of this review is to update the reader on the various bio-molecular alterations in the dental pulp under different clinical conditions: orthodontic treatment (OT), caries, pulpitis and others. The morphological changes in the composition of the DP rang from the reversible remodeling to apoptosis and sometimes necrosis. Many apoptotic factors are involved like Bcl2, Bax and the significant increase in Caspases 9 and 3, as …
