									Fig. 26 Sample taken.
						Fig. 25 A bioptic sample of the complete suture (tooth, bone, soft tissue) is taken, being careful not to damage the area of the operation.
		Fig. 24 The flap is repositioned with a separate stitch.
				Fig. 27 An intimate contact between the subgingival fibrous connective tissue and the surface of the root can be appreciated. A short epithelial attachment is clearly visible. Proceeding towards the apex of the tooth the two tissues tend to separate (Azan-Mallory dyeing).
								Fig. 28 With a stronger enlargement the contact between subgingival connective tissue and cement is even more evident. Some small vascular formations are present near the tooth (Azan-Mallory).
