Melatonin as aRoot Canal
Medicament
• An Emerging Biomolecule in Endodontics
• Presented by: Richa Ranjan
• Department of Conservative Dentistry &
Endodontics
2.
Introduction to Melatonin
•• Naturally occurring hormone (N-acetyl-5-
methoxytryptamine)
• • Secreted by pineal gland
• • Known for regulating sleep-wake cycle
• • Recent interest in dentistry: anti-
inflammatory, antioxidant, regenerative
properties
3.
Why Consider Melatoninin
Endodontics?
• • Inflammation modulation
• • Antioxidant potential
• • Promotes tissue healing
• • Biocompatible
• • Comparable effects to MTA in pulp-capping
models
4.
Formulations Studied
• Application| Form | Study Model
• --------------------------------------
• Final Irrigant | 0.2% melatonin | Extracted
human teeth
• Intracanal medicament | Mixed with Ca(OH)₂
| In vitro
• Systemic for AP | Injection | Rat model
• Pulp capping | Topical gel/tablet | Rat molars

Study 1 –Irrigant Effect
• • Title: Melatonin as an irrigation solution to
enhance sealer adhesion
• • Source: ResearchGate, 2019
• • 0.2% melatonin used after NaOCl
• • Tested with AH-Plus sealer
• • Result: Higher push-out bond strength in
coronal & middle thirds
6.
Study 2 –Animal Model
• • Title: Melatonin for Apical Periodontitis in
Rats
• • Source: Wiley Online Library
• • Induced AP in rats
• • Systemic melatonin given
• • Result: Reduced inflammatory lesion size
and enhanced healing
7.
Study 3 –Melatonin in Pulp
Therapy
• • Source: MDPI / PMC
• • Pulp capping with melatonin
• • Comparable to MTA in dentin bridge
formation
• • Enhanced pulp vitality
• • Reduced cytokines: TNF α, IL 1β, MMP 2

Potential Research Directions
•• As intracanal medicament
• • Combined with Ca(OH)₂ or CHX
• • As root canal sealer additive
• • Long-term in vivo outcomes
• • Effect against E. faecalis and C. albicans
10.
Conclusion
• • Melatoninshows promising results in
endodontic applications
• • Safe, biocompatible, and anti-inflammatory
• • Needs further clinical validation
• • Can be a future biomolecule for regenerative
endodontics
