Unlabelled: The aim of this study was to demonstrate the bony structural changes in deep periodontal pockets.
Material And Methods: Bony fragments were taken from the alveolar wall of a group of 24 patients diagnosed with deep periodontal lesions which required the extraction of certain irrecuperable teeth. Fragments were fixed in glutaraldehyde, then decalcified in EDTA 5% and proccesed for electron microscopic examination and a semifinesse sections to microscop "Zeiss Axioscop".
Results: Both optic and electron microscopy showed: decreaze of bone mineralization and alterations in cholagen structure; the presence of osteoclasts with intense activity and numerous macrofages; at the level of bone marrow, small, insignificant inflammatory reactions, contrasting with the important surrounding modifications; in certain cases though osteolytic reactions occured, the osteoclasts could not by evidenced, on the contrary, numerous macrophages with intense lysosomal enzymes activity were noticed; all the cases showed an alteration of the alveolar bone cholagen.
Conclusion: Thus, we can better understand the role of primary factors in this bony structures.

Background: A comprehensive analysis of the occlusal plane (OP) inclination in predicting anteroposterior mandibular position (APMP) changes is still lacking. This study aimed to analyse the relationships between inclinations of different OPs and APMP metrics and explore the feasibility of OP inclination in predicting changes in APMP.
Methods: Overall, 115 three-dimensional (3D) models were reconstructed using deep learning-based cone-beam computed tomography (CBCT) segmentation, and their accuracy in supporting cusps was compared with that of intraoral scanning models.
