Now I have comprehensive information. Let me compose a thorough answer.
Yes - Same Erosion!
To directly answer your question: Yes, the erosion in your textbook image is exactly the same dental erosion being discussed here. The image shows a dental/operative dentistry textbook answer describing erosion as "wear or loss of tooth surface by chemical action in continued presence of demineralizing agents with low pH" - this is the standard definition. Below is a full write-up.
Dental Erosion
Definition
Dental erosion (also called erosive tooth wear) is the progressive, irreversible loss of tooth structure caused by chemical - not bacterial - processes. Acid dissolves the mineral content of enamel and dentine when the oral pH falls below the critical threshold (pH ~5.5 for enamel, ~6.5 for dentine). Unlike dental caries, no bacteria are involved.
Classification Based on Etiology
Erosion is classified into three types depending on the source of the acid:
A. Intrinsic Erosion
Caused by endogenous (gastric) acids reaching the oral cavity.
1. Recurrent Vomiting
- Eating disorders
- Anorexia nervosa - extreme dietary restriction and profound weight loss; associated with self-induced vomiting
- Bulimia nervosa - cycles of binge eating and purging; most common eating disorder linked to severe dental erosion; palatal surfaces of upper teeth are characteristically affected (called perimolysis)
- Chronic alcoholism - recurrent vomiting and acid reflux from alcohol
- Pregnancy - hyperemesis gravidarum causes repeated exposure to gastric acid
2. Gastroesophageal Reflux Disease (GERD)
- Gastric acid refluxes back into the esophagus and oral cavity
- Prevalence of dental erosion in GERD patients ranges from 17% to 68%
- Considered an "atypical" or extraesophageal manifestation of GERD
- Also associated with chronic cough, hoarseness, laryngitis, and sinusitis
- (Cummings Otolaryngology, block 14)
3. Other systemic causes
- Hiatus hernia
- Gastroparesis
- Rumination syndrome
B. Extrinsic Erosion
Caused by exogenous acids from outside the body.
1. Dietary acids (most common extrinsic cause)
- Carbonated (fizzy) drinks - phosphoric acid and carbonic acid
- Fruit juices and citrus fruits - citric acid
- Sports and energy drinks
- Vinegar-based foods
- Vitamin C (ascorbic acid) supplements and drinks
- Note: titratable acidity (total acid load) is more important than pH alone, as it determines how much acid is available to attack tooth surfaces
2. Environmental/occupational
- Acid fumes in battery manufacturing, electroplating, mining
- Swimming in inadequately chlorinated pools (hydrochloric acid formation)
- Wine tasters (chronic exposure to tartaric acid)
3. Medications
- Aspirin (chewed, not swallowed)
- Iron tonics (acidic liquid formulations)
- Hydrochloric acid supplements (for achlorhydria)
- Chewable vitamin C tablets
C. Idiopathic Erosion
No identifiable cause despite thorough history-taking.
Pathophysiology
When acid contacts the tooth surface:
- pH drops below the critical threshold
- Calcium and phosphate ions are leached out of hydroxyapatite crystals
- The softened surface layer is then lost through normal mechanical forces (tongue, cheeks, toothbrushing)
- Saliva normally buffers and re-mineralizes, but when acid exposure exceeds salivary buffering capacity, net mineral loss occurs over time
Reduced salivary flow (xerostomia from medications, Sjogren's syndrome, dehydration) significantly worsens erosion because saliva's buffering and remineralizing roles are lost.
Clinical Features
| Site of Erosion | Suggests |
|---|---|
| Palatal/lingual surfaces of upper anterior teeth | Intrinsic (GERD, bulimia) - gastric acid pools here |
| Labial/buccal surfaces | Extrinsic (dietary acids) |
| Occlusal surfaces of lower molars | Both intrinsic and extrinsic |
| Generalized/multisurface | Multifactorial |
Signs to look for:
- Shallow, smooth, dish-shaped defects on enamel
- "Cupping" of occlusal cusps
- Restorations standing proud above the dissolved surrounding tooth surface
- Loss of normal anatomical surface detail
- Dentine hypersensitivity
- Dull, loss of translucency in enamel
Management
Management follows a three-stage approach: identify and control causes first, then prevent progression, then restore if needed.
1. Identify and Remove the Cause
- Detailed dietary history - identify acidic foods/drinks and their frequency
- Medical history - screen for GERD, eating disorders, chronic vomiting
- Refer to appropriate specialist: gastroenterologist for GERD (PPI therapy), psychologist/psychiatrist for eating disorders
- Occupational review and protective measures if environmental cause
2. Preventive / Non-Invasive Management
- Dietary counselling: reduce frequency and duration of acid exposure; use a straw for acidic drinks; do not swish acidic drinks
- Timing: advise patients NOT to brush immediately after an acidic episode - wait at least 30-60 minutes (brushing the softened surface causes additional abrasion)
- Fluoride: high-fluoride toothpastes or prescription fluoride gels to remineralize and harden enamel
- Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) products (e.g., Tooth Mousse) to enhance remineralization
- Neutralizing agents: sodium bicarbonate rinses after vomiting episodes (for bulimic patients)
- Saliva stimulants: sugar-free chewing gum to increase salivary flow and buffering
- Night guards/custom trays: can be used to hold remineralizing agents in contact with teeth
3. Restorative Management
Restorative treatment is only initiated after causes are controlled. The choice of material depends on severity, location (aesthetic vs. non-aesthetic), and remaining tooth structure:
- Mild to moderate: composite resin or glass ionomer build-ups to restore lost tooth surface
- Severe: full coverage restorations - crowns, onlays, overlays
- Anterior esthetics: porcelain veneers or composite veneers
- Increased vertical dimension: when extensive tooth loss has reduced the occlusal vertical dimension, full-mouth rehabilitation may be needed
- Palliative: dentine bonding agents or glass ionomers to cover exposed dentine and reduce sensitivity
Restorative materials of choice (as noted in your textbook):
- Esthetic areas: microfilled and flowable composites
- Non-esthetic areas: glass ionomers and amalgam
To Answer Your Question Directly
Yes - the erosion in your textbook image is exactly the same condition. Your textbook (which appears to be a conservative dentistry/operative dentistry exam guide) defines erosion the standard way: chemical tooth loss from demineralizing agents at low pH. It then classifies intrinsic erosion starting with recurrent vomiting - causes such as anorexia nervosa, bulimia, GERD, and alcoholism. This is perfectly consistent with what is described in major medical textbooks. The only difference is the context: in a dental exam, the focus is on the tooth lesion itself and its restoration; in internal medicine or gastroenterology, the same erosion is discussed as a complication of GERD or an eating disorder.

In this page tell me where do you see it's management and where is it

Great - here is a clear breakdown of exactly where erosion management appears on this page:
Where is Erosion's Management on This Page?
Erosion is one of the Noncarious Cervical Lesions (NCCLs) - along with abrasion and abfraction. So its management is not given its own separate heading. Instead, it is covered within the "Management of Noncarious Cervical Lesions" section, which starts in the lower-left portion of the page (you can see it handwritten with "10A" next to it).
A. Preventive Management - Erosion-Specific Points
Within the preventive measures listed, these two points directly address erosion:
| Point in the book | What it targets |
|---|---|
| "Restrict acidic and acid-producing diet" | Manages extrinsic erosion (dietary acids like soft drinks, citrus, vinegar) |
| "Using bicarbonate mouthwash in patients with gastric regurgitation" | Manages intrinsic erosion (GERD/vomiting - neutralizes gastric acid in the mouth) |
| "Topical fluoride application" | Helps remineralize and harden eroded enamel |
The other points (bruxism appliances, occlusal correction, etc.) are more specific to abrasion and abfraction.
B. Restorative Management
The right column of the page covers restoring the lost tooth structure using:
- Composite resins (microfilled composites are material of choice for cervical lesions)
- Glass ionomer cement (releases fluoride, anticariogenic)
- Silver amalgam or direct filling gold
In Short
The management of erosion specifically is embedded inside the broader NCCL management section. The textbook does NOT give erosion its own separate management heading on this page - you have to pick out the erosion-relevant points from the general NCCL management list. The two most important erosion-specific ones are "restrict acidic diet" (extrinsic) and "bicarbonate mouthwash for gastric regurgitation" (intrinsic).
