Table 3. Relative percentage values for compression considering volume (Rel. % of Volume) and Biological Response Units (Rel. %BRU) during application of incisive or molar bite force in pooled incisors and premolars.

	The Relative Percentage of Volume or BRU for Compression in Pooled Canines and Premolars
	Coronal Soft Tissue Follicle		Apical Soft Tissue Follicle
	Incisive Bite Force	Right Molar Bite Force	Incisive Bite Force	Right Molar Bite Force
Rel. % Volume	68.8	62.3	40.1	44.9
Rel. % BRU	80.9	58.3	25.2	40.1

Compression in coronal tissues and tension in apical tissues predominated considering both volume and BRU separately, in both bite force conditions studied.
