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 :

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
