Unfortunately, Soben Peter's Textbook of Public Health Dentistry is not available in this library. The medical library does not contain any dentistry or public health dentistry textbooks at all.
The library currently covers specialities like neurology, cardiology, dermatology, surgery, urology, gynecology, biochemistry, anesthesiology, orthopedics, and several others - but dentistry/dental sciences are not included among the available textbooks.
If you have a specific question on public health dentistry topics (oral epidemiology, dental caries, fluoridation, preventive dentistry, dental public health programs, etc.), I can still try to help you from general knowledge. Just let me know what topic you need!

The library does not have dentistry textbooks, but here is a thorough overview based on established dental knowledge and current web sources:
Inlay Restoration in Conservative Dentistry and Endodontics
1. Definition
An inlay is an indirect, intracoronal restoration fabricated outside the mouth (in a dental laboratory or by CAD/CAM) and then cemented/bonded into a prepared cavity. It sits within the cusps of the tooth - unlike an onlay, which covers one or more cusps.
2. Classification by Material
| Material | Properties | When Used |
|---|---|---|
| Gold (Type II/III alloy) | Strongest, best marginal fit, wear matches enamel | High-stress posterior areas, bruxers |
| Ceramic / Porcelain (e.g., lithium disilicate, e.max) | Best aesthetics, tooth-coloured, brittle | Visible posterior teeth, aesthetic zones |
| Zirconia | Very strong, opaque, less aesthetic | High-load areas |
| Composite resin (indirect) | Good aesthetics, less wear resistance | Moderate defects, patient preference |
3. Indications
- Moderate to large Class I and Class II carious lesions where direct filling is insufficient
- Replacement of large, failing amalgam restorations
- Cracked tooth syndrome (cuspal protection needed - use onlay instead)
- Post-endodontic restoration of premolars and molars (see below)
- Retainer for a fixed partial denture
Contraindications
- Very large destruction (> 2/3 tooth structure remaining) - consider crown
- Poor oral hygiene / high caries risk
- Deep subgingival margins (access/impression difficulty)
- Bruxism (for ceramic inlays - gold preferred)
4. Cavity Preparation Design Principles
General principles
- Taper (Draft angle): 5-15 degrees total convergence toward occlusal to allow path of insertion and withdrawal. Excessive taper reduces retention.
- No undercuts - the cavity must have a single path of insertion.
- Flat pulpal and gingival floors for resistance form.
- Bevels and flares at enamel margins:
- Gold inlays: 30-45° bevel on all enamel margins (creates burnishable metal margin)
- Ceramic/composite inlays: Butt joint margin (no bevel) - bevel weakens thin ceramic
- Occlusal step: Depth ~1.5-2 mm; isthmus width 1/3 intercuspal width
- Proximal box (Class II): Gingival seat flat, buccal and lingual walls flared, clearance of 0.5-1 mm from adjacent tooth
Steps of preparation
- Outline form - define extent based on caries/defect
- Resistance form - flat floors, 90° cavosurface angle for ceramic/composite
- Retention form - parallelism of walls (slight taper only)
- Convenience form - allow instrument access
- Finishing walls and margins
5. Post-Endodontic Inlay/Overlay Restoration
This is a major application. After root canal treatment (RCT), tooth structure is significantly weakened due to:
- Access cavity preparation
- Caries removal
- Loss of moisture in dentinal tubules (reduced fracture toughness)
When to use inlay vs. overlay vs. crown post-RCT
| Remaining tooth structure | Restoration of choice |
|---|---|
| 4 walls intact, small access only | Composite build-up + inlay |
| 2-3 walls remaining | Onlay/endocrown |
| 1-2 walls or cuspal loss | Crown (or overlay) |
| Premolars (functionally loaded) | Onlay/crown to protect cusps |
| Molars with adequate walls | Endocrown (bonded ceramic) |
Key considerations post-RCT
- Endocrown - a single all-ceramic unit that uses the pulp chamber for macro-retention; avoids post placement; good for molars
- Post and core: Required if < 2 mm ferrule available or insufficient coronal structure. Followed by crown, not inlay.
- Ferrule effect: At least 1.5-2 mm of sound vertical tooth structure above the margin is mandatory for crown resistance to fracture.
- The indirect composite inlay study (Dhoum et al., 2018) confirms composite inlays are a valid option when aesthetics and conservation are prioritized.
6. Inlay vs. Onlay vs. Crown - Quick Comparison
| Feature | Inlay | Onlay | Crown |
|---|---|---|---|
| Location | Within cusps (intracoronal) | Covers ≥1 cusp | Full coverage |
| Tooth removal | Conservative | Moderate | Most aggressive |
| Cuspal protection | No | Yes | Yes |
| Best material | Gold/ceramic | Ceramic/gold | Zirconia/PFM |
| Post-RCT use | Limited | Preferred for premolars | Preferred when structure lost |
7. Cementation/Bonding
- Gold inlays: Zinc phosphate or glass ionomer cement (luting); relies on mechanical retention
- Ceramic/composite inlays: Adhesive resin cement (e.g., RelyX, Variolink) after silane coupling and etching - adhesive bonding greatly improves fracture resistance and marginal seal
- Rubber dam isolation is mandatory during cementation
8. Advantages and Disadvantages
Advantages:
- Superior marginal fit vs. large direct restorations
- Better occlusal anatomy and contact point reproduction
- Increased longevity (gold inlays: 20+ years)
- Conservative - preserves more tooth than a crown
- Polymerization shrinkage away from tooth (indirect composite)
Disadvantages:
- Two appointments (or one with CAD/CAM)
- Higher cost
- Microleakage possible at cement interface
- Ceramic brittleness if unsupported
Note: The library does not carry conservative dentistry/endodontics textbooks (such as Sturdevant, Roberson, or Grossman). For BDS/MDS exam preparation, I recommend supplementing this with your own copies of those texts or referencing the Pocket Dentistry cavity preparation resource for further detail.
