Transcript of CLASS V CAVITIES
CLASS V CAVITIESDR SYED ABRAR ALI
Gingival(cervical) third of facial and lingual surfaces)
It is not root caries
May be due to Caries May be due to Abrasion May be due to Erosion Or it may be an Abfraction cavity
TYPES
Class v cavity due to Caries
Basic mechanism is same Patient is a high caries risk Cavities are not shaped angled
Class v cavity due to Abrasion
Usually because of scrub method of brushing
Acidic food, juices and acid from G.I.T can accelerate the process
Absence of plaque and calculus ( no gingivitis /gingival recession may be present)
Sharp angled v shaped cavities
Class v cavity due to Erosion
Cause is acid Usually dietary acid May be regurgitation of acid from
G.I.T Abrasion may also accelerate the
process Not sharp cavities (saucer shaped)
like abrasion and abfraction.
EROSION
Class v cavity due to Abfraction
Loss of canine guidance Heavy occlusal contacts Occlusal interferences Bruxisim and clenching Sharp v shaped cavities shape
cavities
Abfraction
Management of carious cavities
Cavities ….Restorative materials … Composite, gic. Amalgam ,
rmgic,compomers etc Superficial (enamel) use other
methods Fluoride, oral hygein ,diet
Management of Abrasive cavities
First remove the cause Better to use material having good
abrasive resistance properties Amalgam (posterior) Composite (anterior) Gic will soon abrade by brushing
Management of Erosive cavities
Remove the cause Use material having acid resistance
( low solubility and dissolvability ) properties
Amalgam or composite Gic will dissolve quickly
Management of Abfraction cavities
Check occlusion Restore canine guidance ( if
possible) Use flexible material (like microfilled
composite) because these cavities are form in premolars because of excessive load at cervical enamel.
Important considerations
Non surgical and surgical access
Non surgical accessRetaction cordsRubber dam and its clamps
Surgical flaps (mini , mucoperiosteal)Gingivectomy and gingivoplasty
Joke Height of addiction.Just before hanging , judge asked the prisoner “ANY LAST WISH”PRISNONER“YES”I wanted to update my status on face
book as “DEAD”
Thank you………..Any questions
