Characteristics

Characteristics of an Ideal Sealer

Biocompatibility - Initial toxicity is diminished upon complete setting

Minimal Shrinkage upon Setting - Gentle expansion during setting, rather than shrinkage, to ensure a more stable seal

Adherence - A strong affinity for dental surfaces promotes effective sealing and reduces the risk of microleakage

Ease of Mixing - A user friendly mixing process to simplify clinical application

Controlled Setting Time - A slower setting pace accommodates situations necessitating post-space preparation

Radiopacity - Sealer's radiopacity remains comparable to restorative materials to prevent the masking of filling errors

Absence of Pigments - Pigment free composition to eliminate the risk of altering tooth color, as seen with certain sealers containing heavy metals or being ZOE-based

Solvent Dissolvability - Ability to dissolve in solvents aids in retrieval or retreatment scenarios

Tissue and Oral Fluid Insolubility - Preventing solubility in tissue and oral fluids ensures long-term stability

Bacteriostatic Properties - Inhibition of  bacterial growth contributes to a healthier periapical environment

Hermetic Seal Formation - Effective sealing to establish a complete and airtight barrier

Tissue Friendly - Promotes healing and minimizes adverse reactions by avoiding irritation to periradicular tissues

Non-Mutagenic and Non-Carcinogenic - Sealer composition is devoid of mutagenic or carcinogenic properties to prioritize patient safety
