• Deep Dental Caries management is a big problem in dental clinics as dietary carbohydrates ferment by caries leads pH drop  below 5.5, causing demineralization of enamel &  potential damage to underlying tooth structure
• Conventional remedies for oral cavity are conventional grinding hand pieces, lasers and air-blasting apparatus, but these  remedies are not successful.
• Hence, there is a requirement to address said issues by introducing improved Bioceramic mineral using the egg shell waste.

Patent disclosure explains an improved method for  producing a bioceramic mineral releasing  bioactive tetracalcium phosphate cements.

The method comprises the steps of:

• Mixing calcium carbonate of egg shells waste with  dicalcium phosphate anhydrous (DCPA)

• Heating at 1500ºC for 6-12 hours in order to  synthesize Tetracalcium phosphate

• Mixing synthesized Tetracalcium Phosphate with  the liquid component of the cement containing  1M disodium hydrogen phosphate (Na2HP04)  containing 10% citric acid using dental cement  spatula in L/P ratio of 0.5mI/g

• Packing the mixture in a mold and allowing the mixture  to harden for obtaining improved Bioceramic mineral  releasing Bioactive Tetracalcium Phosphate Cements.

• The said method further induce secondary dentin formation due to sustained calcium hydroxide release of the Bioceramic material.
• The Tetracalcium phosphate cement is modified by addition of other calcium phosphates having Ca/P ratio lower than 2.
