Premium member Presentation Transcript TOOTH ISOLATION: TOOTH ISOLATION PowerPoint Presentation: It is preparation of endodontic field free off saliva and other contaminants that complicate dental work. PowerPoint Presentation: Goals of Isolation PowerPoint Presentation: Moisture control PowerPoint Presentation: Access and visibility PowerPoint Presentation: Harm prevention PowerPoint Presentation: Prevent accidental swallowing of restorative materials and instruments PowerPoint Presentation: Safe and aseptic endodontic field Efficiency and patient satisfication: Efficiency and patient satisfication Methods for Isolation: Methods for Isolation Rubber Dam Isolation Cotton roll isolation High volume evacuator and saliva ejector Retraction cords Mirror and Evacuator tip retraction Mouth Props drugs Rubber Dam: Rubber Dam Advantages: Advantages Isolation of the operating field Improved access and visibility Protection of patient’s airway Protection of patient’s soft tissues High patient acceptance – Allow to Relax No gag reflex Keep the tongue Operating efficiency Time saving Disadvantages: Disadvantages Time consumption Patient’s objection Conditions where rubber dam not used: partially erupted teeth Some third molars Extremely malpositioned teeth Asthma patients Psychological reasons Latex allergy Mouth breather Materials and Instruments: Materials and Instruments Rubber dam material Rubber dam holder Rubber dam retainer(clamp) Retainer forceps Punch Napkin Lubricant Dam material: Dam material 2. Holder or frame: 2. Holder or frame Maintains the borders in position three types Nygaard-Ostby ( plastic ) The Sauveur folding frame: The Sauveur folding frame has centrally placed hinges that allow one side to be opened. 3. Retainers (clamp): 3. Retainers (clamp) PowerPoint Presentation: Two types: 1. wingless 2-Winged clamp: 2-Winged clamp PowerPoint Presentation: ANTERIOR TEETH (ivory no 9 , 212) PREMOLAR TEETH ( no 0 , 2 ) MOLAR TEETH ( no 14 . 14A . 56 ) UNIVERSAL CLAMP DESIGNS: UNIVERSAL CLAMP DESIGNS BUTTERFLY IVORY NO 9 AND NO 56 ARE SUITABLE FOR MOST ISOLATION TETTH WITH ABNORMAL SHAPE CROWN OR SMALL REDUCED CROWN no ( O. 9 .14 ) DEEP REACHING CLAMP 5. Retainer Forceps: 5. Retainer Forceps for placing and removal of retainer 6. Punch: 6. Punch For producing holes in the rubber dam for the teeth 7.Napkin : 7.Napkin Between rubber dam and patients skin Reduce allergic reaction Absorbs saliva Placement of rubber dam: Placement of rubber dam 3 methods Dam first technique Clamp first technique Clamp and dam together technique PowerPoint Presentation: Oraseal putty sealant has been applied for extra protection Removal of rubber dam: Removal of rubber dam Cutting the septa Removing the retainer Removing the dam Wiping the lips Rinsing the mouth Massaging the tissue and Examining the dam Variations with age: Variations with age For younger - change the hole size - smaller sheet Primary teeth- HF no.27 retainer Young permanent teeth – Ivory no. 14 Errors in application and removal: Errors in application and removal Prevent adequate moist control Reduce access and visibility Cause injury to patient off centre arch form Inappropriate distance between holes Incorrect arch form of holes Inappropriate retainer Shredded or torn Dam Sharp tips of no 212 retainer PowerPoint Presentation: Special Cases Application of a rubber dam over a fixed orthodontic appliance : Application of a rubber dam over a fixed orthodontic appliance Deep coronal destruction: Deep coronal destruction Deep reaching clamp for badly decayed teeth: Deep reaching clamp for badly decayed teeth THE SPLIT-DAM TECHNIQUE: THE SPLIT-DAM TECHNIQUE PowerPoint Presentation: Isolation of a bridge isolate a badly broken-down tooth Isolate a badly broken-down tooth : Isolate a badly broken-down tooth Sealing the edges with a caulking agent. An orthodontic band: An orthodontic band clamp can easily be fitted Mirror and suction tip: Mirror and suction tip Cheek , lip and tongue retraction Cotton roll isolation: They are absorbents Provide moisture control with saliva ejector Cotton roll isolation High volume evacuator and saliva ejector: High volume evacuator and saliva ejector For suctioning water and debris Advantages -both solid and liquid -improve access and visibility -prevent dehydration of oral tissues Retraction cords: Retraction cords Control sulcular fluid Vasoconstrictor (epinephrine) along this Prevent excess restorative materials from entering the gingival sulcus Mouth props: Mouth props For lengthy appointments For relieving patients mouth muscles 2 types 1. block type- low cost 2. ratchet type- large size and high cost Drugs : Drugs Rarely indicated Atropine(antisialogogues)-5mg,30min before the procedures-reduce salivation Referances : Referances Color Atlas of Dental Medicine – Endodontology Endodontics - problem_solving_in_clinical _ practice_2002 Color Atlas of Dental Medicine - Endodontology Abdalrahman gamal abd-allah cairo university : Abdalrahman gamal abd-allah cairo university T _ 01007484960 THANK YOU You do not have the permission to view this presentation.
