This study tests whether oxymetazoline, a common nasal decongestant, can replace sodium hypochlorite as a bleeding control agent during pulp treatment in children's baby teeth. About 50 Egyptian children aged 4-8 with decayed molars will receive either treatment. The goal is to s…

This study tests whether a robot can place dental implants more accurately than a computer-guided navigation system in the front upper jaw. Twenty-four adults needing an implant will be randomly assigned to one of the two methods. The main goal is to see which approach achieves b…

This study compares mustard gel, made from black mustard seeds, to a standard dental material (MTA) for treating deep cavities in baby molars. 72 children aged 6-8 will receive one of the two treatments after the damaged nerve is removed. The goal is to see if mustard gel can kee…

This study tests whether graphene oxide can successfully treat decayed baby teeth that need pulp therapy. 126 children will be split into groups receiving graphene oxide, standard materials like MTA or zinc oxide, or a lesion sterilization technique. The goal is to see which appr…

This study will compare three methods for testing whether a tooth's nerve is alive (vital) or dead (nonvital): laser Doppler flowmetry, cold testing, and electric pulp testing. About 150 people who need root canal treatment will receive all three tests before treatment. The goal …

This study compares two ways of numbing a child's tooth for a root canal on a baby molar: a computer-controlled system that delivers anesthetic slowly and steadily, versus a traditional injection. The goal is to see which method causes less anxiety and pain in children aged 6 to …

This study tests whether using a dental operating microscope during a pulpotomy (a partial root canal) reduces pain and improves quality of life afterward. 82 adults with deep cavities and tooth nerve pain will be randomly assigned to get the procedure with or without the microsc…
