  • Intracanal MedicamentsINDIAN DENTAL ACADEMY Leader in continuing dental education www.indiandentalacademy. com
  • Introduction Disinfection – Destruction of pathogenic microorganisms Pre-requisites  Removal of pulp tissue  Cleaning and shaping by biochemical means  Irrigation ICM – Reduces or eliminates microbial flora in root canal www.indiandentalacademy.com
  • Root canal flora Gram +ve, Gram –ve organisms, yeasts, obligate and facultative anaerobes Factors that delay healing  Trauma  Devitalized tissue  Dead spaces  Accumulation of exudate www.indiandentalacademy.com
  • Ideal requirements of ICM Effective germicide and fungicide Nonirritating to periapical tissues Remain stable in solution Have a prolonged antimicrobial effect Active in presence of blood, serum and protein derivatives of tissue Low surface tension Not interfere with repair of periapical tissues Not stain tooth structure Capable of inactivation in a culture medium Not induce a cell-mediated immune response www.indiandentalacademy.com
  • Function of ICM Most are antimicrobial agents  Irrigation and instrumentation reduces microorganisms  ICM destroys those remaining and limits the growth of any new arrivals Corticosteroid-antibiotic combination is useful in treating apical periodontitis www.indiandentalacademy.com
  • Intracanal Medicaments1. Phenol and related volatile compounds2. PBSC paste3. Sulfonamide and sulfathiazole4. Corticosteroid-antibiotic combination5. Calcium hydroxide6. N27. Halogens8. Quaternary ammonium compounds www.indiandentalacademy.com
  • 1. Phenol and related compounds Phenol Eugenol CMCP Cresatin Formocresol Glutaraldehyde Cresol, beechwood, creosote, and thymol www.indiandentalacademy.com
  • 1. Phenol and related compounds Phenol  Protoplasm poison, causes necrosis of soft tissue Eugenol  Antiseptic and anodyne CMCP  2 parts parachlorophenol and 3 parts gum camphor  Has wide antibacterial spectrum, effective against fungi  Much less irritating  Inexpensive and long shelf life www.indiandentalacademy.com
  • 1. Phenol and related compounds Cresatin  Same actions as CMCP, less irritating Formocresol  Formalin and cresol  Formalin – strong disinfectant  Used in pulpotomy  Nonspecific bactericidal medicament Glutaraldehyde – 2 %  Slightly acidic  Strong disinfectant and fixative www.indiandentalacademy.com
  • 2. PBSC paste Penicillin – effective against Gm+ve org Bacitracin – effective against penicillin- resistant org Streptomycin – effective against Gm-ve org Caprylate – effective against fungi PBSN – Nystatin instead of Caprylate Disadv – interfere with subsequent culture procedure, allergic reaction to drugs www.indiandentalacademy.com
  • 3. Sulfonamide and sulfathiazole Yellowish tooth discoloration Used when tooth has been left open after an acute periapical abscess www.indiandentalacademy.com
  • 4. Corticosteroid-antibiotic combination Highly effective in the treatment of overinstrumentation Corticosteroid – reduces periapical inflammation and relieves pain Antibiotic – prevents overgrowth of microorganisms www.indiandentalacademy.com
  • 5. Calcium hydroxide Weeping canal  Constant clear or reddish exudation associated with large apical radiolucency  Asymptomatic or tender to percussion  Negative cultures Treatment  Dry the canal with sterile absorbent points  Place calcium hydroxide paste as in apexification Mech of Action  High pH has destructive effect on bacterial cell membranes and protein structures www.indiandentalacademy.com
  • 5. Calcium hydroxide Mode of application  Ca(OH)2 is mixed with sterile water or saline to a thick paste  Paste is condensed into the root canal to a dense fill www.indiandentalacademy.com
  • 6.N2 Both ICM and sealer Contains  Paraformaldehyde (primary ingredient)  Eugenol  Phenylmercuric borate  Lead  Corticosteroid  Antibiotics and perfume Antibacterial effect is short lived (7 to 10 days) www.indiandentalacademy.com
  • 7. Halogens Sodium hypochlorite  Chlorine has greatest disinfectant action  Vapour is bactericidal  Action is short lived Iodides (KI – Potassium iodide)  Used as antiseptics  Iodine is highly reactive  Combines with protein in a loosely bound manner  Destroys microorganisms by forming salts  Action is short lived but less irritating www.indiandentalacademy.com
  • 8. Cationic Detergents Quaternary ammonium compounds  Odorless and stable solutions  Low surface tension and good cleansing effects  These are +vely charged  React with bacteria which are –vely charged 9-aminoacridine  Mild cationic antiseptic  Stains the tooth structure www.indiandentalacademy.com
  • Irritation potential of ICM Essentail oils and formocresol – High CMCP and Cresatin – Moderate NaOCl and H O - Less 2 2 www.indiandentalacademy.com
  • Recommendations 2 medicaments chosen as ICM Iodine potassium iodide  Most effective and safest  Very short acting – 3 days Calcium hydroxide  Long acting  Less irritating www.indiandentalacademy.com
  • Intracanal Medication Method  Absorbent point moistened with ICM is carried into the canal  Medicated cotton pellet is placed in the pulp chamber  Access cavity is sealed with temporary filling material Frequency  Renewed in a week  Not longer than 2 weeks www.indiandentalacademy.com
