Dental Erosion (Amaechi 9) Flashcards
Dental erosion (_____tooth wear) is the loss of dental hard tissue through either chemical etching and dissolution by acids of ______ and/or by ______.
- Erosive
- non-bacterial origin
- chelation
Sources/concentration of Acid
- Gastric
- Dietary
- Environmental
- Acids with Ca-chelating properties in foods/beverages
Differences of Caries and Erosion
- Sources
- Pathogenesis
- Histopathology
Examples of chelator
Citric acid
Types of tooth wear
- Attrition
- Non-carious cervical lesion
- Abrasion
- Erosion
Two theories for Non-carious cervical lesion
- Horizontal tooth brushing with commercial toothpaste
- Disruption of inter-molecular bonds causes damage in the subsurface; eventually micro-cracks are formed
Features of erosion
- Change in texture
- Perikymata absent
- Silky-shining appearance of enamel
Prevalence figures indicates that acid erosion is a global oral health problem, especially among ______ and ______.
children and adolescents
Intrinsic causes of Erosion
- GERD
- Bulimia nervosa
- Gastric Surgery
- Cyclic or Psychogenic vomiting syndrome
- Pregnancy-induced vomiting
- Chronic alcoholism
- Binge drinking
Extrinsic causes of erosion
- Dietary
- Occupational
- Medications (Antidepressants, Sphincter-relaxing medications)
- Lifestyles (Illegal drugs, Lactovegetarians)
pH and ______ of foods and drinks are important in the assessment of erosive potential
Titratable acidity
- Oral biofilm
- Tooth structure and composition
- Saliva
- Oral soft tissues
- Temperature of agent
- Frequency of exposure
Erosion modifying factors
Prevention and Control of Erosion
- Early Diagnosis
- Recording and monitoring the Clinical situation
- Deal with underlying medical disorders
- Preventive strategies
- Establish Continued Care Regime
Protection of eroded surface
- Dentin bonding agent
- Adhesively retained resins
- Fluoridated sealants
- Porcelain veneers
Health education/Counseling: _______ and directed to the causative factor of the individual’s case
Individualized
