GIT and Tooth Surface Loss Flashcards
What term describes the loss of enamel and dentine primarily from chemical attack other than those chemicals produced intraorally by bacteria ?
Erosion
What are the 4 key outcomes of erosion?
- dentine hypersensitivity
- rim of confidence
- sub margination
- chipping
What term describes gradual destruction of material, usually metal, by chemical reaction with its environment?
corrosion
During erosion, what must H+ diffuse through?
plaque and pellicle
During erosion what does H+ penetrate?
the protein/ lipid coating of hydroxyapatite crystals
Why is the surface area of dentine higher than that of enamel?
its crystals are smaller
What does dentine higher surface area make it more ?
acid soluble
How does H+ dissolve tooth?
combining with carbonate/ phosphate ion and complexing with calcium, removing it from the lattice.
Combining with carbonate/ phosphate ion and complexing with calcium, removing it from the lattice - is known as?
subsurface softening
What does subsurface softening give opportunity to?
repair and reverse by remineralisation
What may tooth erosion be the first sign of?
- eating disorders
- psychological health
- suicide risk
- medical risk
What questionnaire would be asked to patients with suspected eating disorder?
the SCOFF questionnaire
What should you look out for in patients who have an eating disorder?
- denial and shame
- attempt to conceal condition
- unexplained weight loss, abdominal and gynaecological problems, sleeping lethargy, and fatigue
- sore throat from recurrent vomiting
What questionnaire is used for patients with suspected alcoholism?
the CAGE questionnaire
What can GORD progress to if untreated?
- oesophagitis
- Barrett’s epithelium
- oesophageal adenocarcinoma
- aspirational pneumonitis
