Periodontology Periodontology  Periodontal tissues  alveolar bone  cementum  periodontal ligament  gingiva crown root Dentogingival junction Morphology Supportive tissues Periodontal diseases  Inflammation at most!!!!  The most important ethiological factor? Dental plaque!!!! BIOFILM Dental plaque = biofilm  Comunity  Primitive circulation More species Higher metabolic activity Higher resistance (S. sobrinus CHX 300x, AF 75x) better conditions to survive higher virulence Biofilm  Adherence  Colonisation  Maturation Can it be recognised and removed easily? Othe aethiological factors  Calcified deposit on teeth, plaque on the surface  Overhangs, crowns, dentures  Genetic factors – gen polymorphism Parodontopathies Gingivitis  Plaque associated gingivitis Erythema No pain Easy bleeding Plaque on the tooth Chronic form Acute form Erythema Pain Easy bleeding Plaque on the tooth Acute necrotisans gingivitis - ANUG  Necrotizing ulcerative gingivitis Aetiology Special microbs - anaerobs The clinical picture  Gingival inflammation and destruction Severe pain, bleeding gums, halitosis Diferential diagnosis  Herpetic gingivostomatitis - Young people - Prodroms - Pyrexy - Lymphadenopathy - Lesions more widespread and diffuse Diferential diagnosis  If ANUG does not tend to recover in 10 days – check the blood picture! ! Atrophic or desquamative gingivitis symptoms  Erythema on free gingiva – loss of the epithelium  Variety of symptoms: itching, tenderness of eating, burning. Hyperplastic gingivitis  High standard of oral hygiene must be achieved!  Gingivectomy (drugs induced) Parodonthopaties Periodontitis  Chronic periodontitis.  Aggressive periodontitis.  Periodontitis as a manifestation of systemic disease.  Necrotizing periodontal diseases.  Abscesses of the periodontium.  Periodontitis associated with endodontic lesions.  Development or acquired deformities and conditions.

Oral hygiene - professional, home care INDIVIDUAL Therapy  1. Oral hygiene - professional, home care INDIVIDUAL Therapy  1. Oral hygiene - professional, home care INDIVIDUAL Scaling, root planing Therapy  2. Subgingival treatment – scaling root planing, curettage Therapy  3. Periodontal surgery Gingivectomy, gingivoplastic Indications of gingivectomy  Hyperplasia gingivae (pseudopockets)  Supraalveolar periodontal pockets with the horizontal bone resorption  - Bad configuration of the gingival margin or papilla fol. ANUG or extraction. Gingivectomy Gingivoplastic Internal gingivectomy External gingivectomy Intrasulcular Marginal Paramarginal Papilar Paramedial Medial Closed curretage Flap operation Modified Widman flap Apical flap, replaced flap Papilla preservation technique Wedge excision Apical flap Replaced flap Mucogingival surgery  Enlargement of attached gingiva - Frenulectomy - Vestibuloplastic  Plastic of recessus -Lateral flap -Bridge flap -Mucous or mesenchymal grafts
