Presentation Transcript

  1. Helen screw installation

  2. Advantages of laser surgery • No bleedings • Exactcut • Reducedoperationtime • Shortpostoperative period • No pain • No edema • Consistency of results during postoperative period

  3. 5. Physiotherapy

  4. 6. Periodontal space processing

  5. 7. Photodynamic therapy

  6. Photodynamic therapy Photodynamic therapy – is a method, based on use of various photobiological effects, caused by means of join application of light, oxygen and photosensitizer (Vladimirov V., 1989).

  7. Devices for photodynamic therapy 660 nm 635 nm

  8. Str. mutans Muller., 2004 (adapted byCarlsson, 1989)). Streptococcus Actinomyces р-aminobensol Capnocytophaga E.Corrodens A.actinomycetemcomitans NH4+ CO2 Lactat Fusobacterium Eubacterium Porphyromonas Prevotella Peptococcus Peptostreptococcus Phormiatт Veillonella Н2 Tooth Gingiva Tiaminpirophosphate Putrescine Isobutirat Acetat VitК Treponema Campylobacter P.melaninogenica P.Intermedia P.gingivalis Progesteron Estradiol Eubacterium alactolyticum Gemin T.denticola Caproat α2-globulin Amino acids

  9. Mechanism of action of photodynamic therapy photosensitizer reactions molecules of a photosensitizer Laser radiation microbic cell O- O- O- O- O- R- R- 1) Chemical interaction of molecules - free radical reactions: increase in quantity of the hydroxyl, superoxid, peroxid ions, bringing to oxidation-reduction reactions R- 2) Interaction with oxygen and formation of reactive oxygen speciesand subsequent cascade of oxidation-reduction reactions result: lysingof membranes and components of bacteriacells.

  10. Antibacterial effects Staphylococcusaureus Streptococcusmutans Streptococcussanguis Streptococcussobrinos Streptococcuspyogenes Lactibacilluscasei Lactibacillusfermentum Actinomecesviscosus Porphyromonasgingivalis Fusobacteriumnucleatum Actinobacillusactinomycetemcomitans Salmonella enteridis Clostridiumperfingens Klebsiella pneumonia Escherichiacoli Pseudomonas aeroginosa Prevotellaintermedia Micoplasmahominis Candida albicans
