The best indication for osseous grafts for bone regeneration procedures is three-walled infrabony pockets.

agranulocytosis, leukemia, and granulocytopenia—can significantly impact the health of the gingiva by affecting the immune response and increasing susceptibility to infections. 

The early effects of primary trauma from occlusion can include hemorrhage and thrombosis in the periodontal ligament, leading to inflammation and potential tissue damage.

• Distal inclines of buccal cusps of mandibular first premolars and mesial inclines of lingual cusps of maxillary first premolars
• These specific occlusal surfaces are common areas where contacts can develop prematurely, emphasizing the importance of careful occlusal adjustments.

Secondary occlusal trauma primarily relates to occlusal discrepancies or effects on tooth mobility due to periodontal attachment loss rather than localized gingival inflammation alone.
