Transcript

  • 1. H.K.Ajeya Ranganathan G D C R I , Bangalore.
  • 2. * Periodontitis is one of the most common oral diseases and is characterised by gingival inflammation and alveolar bone resorption * Periodontitis is a multifactorial and cumulative condition, initiated and propagated by bacteria and host factors * There are two forms of periodontitis; chronic and aggressive Periodontitis * Both differ from each other not only in clinical findings but also age of onset and rate of progression.
  • 3. * *Factors playing role in Periodontitis are  LOCAL FACTORS like calculus, food impaction and microbial plaque which includes Aggrobacter actinomycetemcomitans, Bacteroides forsuthus & Prevotella intermedia , Fusobacterium nucleatum , Bacteroides melaninogenicus ENVIRONMENTAL FACTORS Cigarette smoking, beedi, Smokeless tobacco usage like beeda, pan masala, pan chewing, Gutka SYSTEMIC FACTORS
  • 4. * Environmental factors are not found in oral cavity always but are acting as and when habits are cultivated * Environmental factors include * SMOKING * Pan chewing * Smokeless tobacco consumption and * Poor dental awareness
  • 5. * Acetone Aluminium Ammonia Arsenic Benzene Butane Cadmium Carbon monoxide Carbon dioxide Chloroform Cyanide DDT/Dieldrin Ethanol Formaldehyde Hydrogen cyanide Lead Methanol Nicotine Tar Vinyl Chloride * 1. Filter made of 95% cellulose acetate. * 2. Tipping paper to cover the filter. * 3. Rolling paper to cover the tobacco. * 4. Tobacco blend.
  • 6. Rolling paper Tobacco blend Cigarette filter Cigarette but • Holds tobacco blend • Controls the rate of burning and production of ash • It provides taste and flavour • It may vary from region to region • It is the biodegradable part of cigarette made of cellulose acetate. • It filters the main stream of smoke from tobacco blend to the mouth piece • It holds the burnt ash and remnants of tobacco • It is 30% of the length of a cigarette
  • 7. * Gingivitis: smokers develop less inflammatory response than non smoking counterparts which shows that occurrence of gingivitis is comparatively low in smokers than in non-smokers * Periodontitis Smokers are more prone to periodontitis than non smokers since smoking plays an important role in destruction of periodontium , loss of attachment and sub-gingival plaque accumulation.
  • 8. Serum Osteoprotegerin levels increased initially followed by decreased gradually M-CSF, OPG , PGE2 are decreased Saliva OPG levels decreased and sRANKL levels increased OPG/sRANKL ratio is reduced
  • 9. * Increased destruction of periodontia by smoking would lead to the breakdown balance between microbial colonies and host immune response and causes changes in the contents of sub-gingival plaque * This would lead to increased virulence and changes the host response to the bacterial challenge which in turn lead to increased periodontal destruction
  • 10. Increased levels of T.forsythia , T.denticola, P.gingivalis Increased tissue destruction Increased colonization of bacteria in sub gingival plaque Impaired mechanical prophylaxis
  • 11. Increased levels of TNFα and matrix metalloprotien 8 Decreased levels of neutrophils and PGE2 Impaired neutrophil activity Increased risk of tissue destruction
  • 12. Decrased GCF production Decreased blood flow Decreased Microvasculature Added vasoconstriction Decreased Inflammatory response Slow recovery from Local anaesthasia
