Effects of Orthodontic Forces Very Controversial Some reseachers have found it to be deleterious to tooth vitality (Mostafa et  al. 1991) Others reported that this force has no significant effect on Dental Pulp  (Butcher and Taylor 1952; Huettner and Whitman 1958; Subay et al. 2001) Reported to repress the DP tissue respiration rate (Unsterseher et al. 1987).  Cause apoptosis (Rana et al. 2001) Tissue damage, edema, and fibrosis (Taspinar et al. 2003)  Increase capillary numbers(Nixon et al. 1993; Derringer et al. 1996) Disturb blood circulation (Vandevsha-Radunovic et al. 1994) Chronic Parafunctional forces from clenching and bruxism cause pulpal  inflammation, elevated intrapulpal pressure, and deposition of calcified  nodules )Burke and Samarawickrama 1995) Trama-induced dentin formation and pulp calcification occur in response to  intrapulpal pressure  (Spahr et al. 2002)
