Case Study on Calcium hydroxide

Here’s a case study on the use of calcium hydroxide in dentistry:

Patient X visited a dental clinic with a complaint of toothache. After a thorough examination, the dentist diagnosed that the patient had a deep cavity in one of the molars that required treatment. The dentist recommended a root canal treatment to remove the infected pulp and save the tooth.

During the root canal procedure, the dentist removed the infected pulp and cleaned the root canals. To protect the tooth pulp and promote healing, the dentist applied a layer of calcium hydroxide paste as a temporary filling material. The calcium hydroxide paste was used as a liner to help stimulate the formation of dentin and promote the healing of the tooth.

After two weeks, the patient returned for a follow-up visit. The dentist removed the temporary filling material and placed a permanent filling. The tooth was restored to its normal function and the patient reported relief from the toothache.

Calcium hydroxide is commonly used in dentistry as a cavity liner because of its antimicrobial and tissue healing properties. It helps protect the tooth pulp from further damage and promotes the formation of dentin. The use of calcium hydroxide as a liner has been shown to improve the success rate of root canal treatments.

In conclusion, the use of calcium hydroxide as a temporary filling material and cavity liner in dentistry can help promote the healing of teeth and improve the success rate of root canal treatments. However, it is important to follow proper guidelines and precautions when using calcium hydroxide to ensure the safety and well-being of the patient.
