Oral Surgery YR3 Flashcards
What procedures count as oral surgery?
- Simple exodontia - extractions- Complex exodontia - MOS- Soft tissue surgery - biopsy- Oral pathology management - tumours- Anxiety management - sedation- Medical condition management
What PPE is needed for simple exodontia?
Level 2 PPE:- eye- mask- apron- gloves
What are the legal considerations needed to allow simple exodontia?
- Clear documented treatment plan- Medical history up to date- PreOP radiograph- Patient confirms reason for attendance and the tooth extraction
What is the definition of luxation?
Displacement or dislocation of an object
What is the definition of elevation?
The action of moving an object from its original position in a vertical plane
What is the definition of extraction?
The complete removal of an object from its surroundings
What are the 3 forms of techniques for simple exodontia?
- Luxation- Elevation- Extraction
What is the definition of point of application?
The point at which an instrument becomes active and applies force to an object or surface
What is the point of application for a luxator? and in which area of the tooth?
- At the periodontal ligament space| - Used in the long axis of the tooth
What is the process of using a luxator?
- Gentle apical pressure with lateral cutting action| 2. Incise the PDL, wedges between alveolar one and root surface
What is the point of application of an elevator? and what orientation and movement is it used?
- Interproximal point of application- With a perpendicular orientation- Rotational movement (pulley lever)
What is needed when using elevators?
Fulcrum
What is the definition of primary drive?
Refers to the action used with a luxating or elevating instrument with utilisation of lever and fulcrum rests
What is the definition of primary movement
First stages of dental extraction by severing the PDL fibres and encouraging dilatation of alveolar bone
What is the definition of secondary movement?
Forceps are applied to the coronal section of the tooth to be extracted
What is the definition of secondary drive?
Forceps are used to grip and apply apical pressure
What other movements are used when using a forcep/
Rotational movement and 8-figure movements
How to use luxators safely?
Instrument in heel of hand, index finger guides tip, supporting digits straddle alveolus of quadrant
How to use elevators safely?
Instrument in heel of and, index finger guides tio, fulcrum on alveolar bone, perpendicular to extracting tooth, supporting digits straddle alveolus of quadrant
How to use forceps safely?
Operating gand conforms to grip of instrument, supporting hand reciprocates apical pressure and lateral movements
What is the order of use when extracting a tooth?
- wide narrow luxator2. elevators: starting with smallest3. delivery of tooth with extraction forceps using secondary movements
What are the ergonomics when extracting a tooth?
- Standing- Right handers: LRQ standing behind and other quadrants in front- Upper teeth: patient high ad supie- Lower teeth: patient low ad upright- Supporting and reciprocates apical pressure and provides proprioceptive feedback
What are some peri-operative complications for simple exodontia?
- ineffective La- excess bleeding- crown or root fracture- root displacement- communication- adjacent tooth damage- soft tissue injury- alveolar fracture- instrument fracture- tooth inhalation
What are some post-operative complication of simple exodontia?
- Pain- Swelling- Bruising- Bleeding- Dry socket- Infection- Trismus- Difficulty eating- Prolonged healing
What is normal bleeding and how to deal with excessive bleeding?
- Haemostasis within 3-5 minsIf continues:- apply Pa- place haemostatic agent in socket- suture socket with resorbable suture- rest with no mouth rinsing then reapply pressure
How to deal with crown/root fracture? and what increase the risk?
- Should anticipate from pre-OP radiograph- Heavily restored, RCT, curved morphology- Refer to MOS`
How a communication forms? and how to deal with a sinus communication?
Loss of alveolar bone leading to communication| - Refer to MOS
How to deal with a dry socket?
- Occurs 3-5 days postOP- Painkillers ineffective- Bad taste- Increased in smokers- Treatment irrigate with saline and dress with alvogyl
What is essential to ask a patient before extracting a tooth, in regards to their wellbeing?
Have they eat?, if not offer a glucose-based supplement
What is the relevant previous medical history, when assessing the difficulty of an extraction?
Bleeding disordersBisphosphonatesAntibiotic allergyAnticoagulants and Antiplatelets
Refer to the SDCEP guidelinesRadiotherapyChemotherapyHaemophiliaLiver/Kidney failureEssential to liaise with necessary colleagues
What are the radiographs of choice for a extraction?
DPT and periapical
What consentual aspects must the patient know and understand for you to undertake an extraction?
- The tooth to be extracted- risk vs benefits- justification for extraction- other viable options
What medical aspects must you understand before starting an extraction on a patient?
- Changes since last visit- Changes to bleeding and healing times (anti-coagulants, immunosuppression or bisphosphonates)- Diabetes control- Has the patient eaten?
What should be included on the surgical safety checklist before a tooth extraction?
- Team awareness- Patient points to tooth- Dentist identifies tooth- X-rays present- Previous medical history- Clearly planned and recorded
What equipment is essential for an extraction?
PPE: level 2LA: topical, long/short needle, appropriate LA for patient's needsExtraction instrumentsGausePost OP instruction leaflet
What position of the patient is gold standard for a lower tooth?
Low and upright
What position of the patient is gold standard for a upper tooth?
Higher and more supine
What is the role of the working/dominant hand?
Control the extraction instrument
