No, the root canal procedure is not supported by the diagnosis since the x-ray did not reveal any cavities or infections
Step-by-step explanation:
A root canal treatment is an endodontic treatment done when the root canal is infected by oral bacteria which invade and infects the tooth.
The infection usually follows tooth decay, tooth damage due to fall or trauma, or any leaky tooth filling.
In order to confirm the damage or infection caused in the tooth, the dentist takes a periapical tooth x-ray to visualize the entire tooth structure along with root and attachment to the jaw to detect any infection.
The dentist looks for any periapical radiolucencies in the dental x-ray which denotes infected part in the tooth and only if the x-ray shows an infection of the root pulp, a root canal treatment is warranted.
