Classification of Dental cements based on their uses

Dental Cements have multiple uses in Dentistry based on the requirement from patient to patient, and it also differs from tooth to tooth in the same patient. The front or anterior teeth (incisors, canine) require aesthetics more than strength and it is the opposite in the posterior or the molars. So it is essential to know which type of cement should be used in which scenario. Some of the common uses of Dental cements in dentistry are:

In Restorative Dentistry Dental Cements are used  as:

• Cavity Liners
• Base: Below restorations to protect the pulp chamber from mechanical and thermal forces. They are of two types High Strength and Low strength
• Restoration: Temporary and Permanent, Cementation: Temporary and Final (permanent).

Final cementation:	Eg: Reinforced zinc oxide eugenol, zinc phosphate, zinc silico-phosphate, zinc polycarboxylate, glass ionomer
Temporary cementation	Zinc oxide eugenol
Permanent restoration	Glass ionomers, resin-modified glass ionomers, Composites, Amalgam
Temporary restoration	Zinc oxide eugenol, zinc phosphate,  zinc polycarboxylate, silicate
Anterior restorations	Eg: Composites, Silicate, Sillicophosphate, Glass ionomer
High strength bases	Eg: Reinforced zinc-oxide eugenol, Zinc phosphate, Zinc polycarboxylate, Glass ionomer
Low strength bases	Eg: zinc oxide eugenol, calcium hydroxide
Cavity liners	Eg: calcium hydroxide
Root canal sealer	Eg: zinc oxide eugeol, zinc poly carboxylate
Gingival tissue pack	Eg: zinc oxide eugenol
Surgical dressing	Eg: zinc oxide eugenol, zinc oxide preparation
Cementation of orthodontic bands	Zinc phosphate, zinc poly carboxylate

In Endodontics:

• Root canal sealer
• Temporary cementation during Root Canal Therapy
• Permanent restoration after Root Canal Therapy

Prosthodontics:

Dental cements are mainly used in cementation of crowns which are of two types

• Temporary Cementation
• Permanent Cementation

Periodontics:

As Gingival Tissue pack after Flap surgery or any Gingival Surgical procedure

Orthodontics:

For cementation of bands stainless steel as well as ceramic bands

Dental cements play an integral part of all branches of dentistry and based on the requirement different types of cements are used as seen in the classification table mentioned above.
