- Dental radiographs are commonly called X-rays. Dentists use radiographs for many reasons: to find hidden dental structures, malignant or benign masses, bone loss, and cavities.
A radiographic image is formed by a controlled burst of X-ray radiation which penetrates oral structures at different levels, depending on varying anatomical densities, before striking the film or sensor. Teeth appear lighter because less radiation penetrates them to reach the film. Dental caries, infections and other changes in the bone density, and the periodontal ligament, appear darker because X-rays readily penetrate these less dense structures. Dental restorations (fillings, crowns) may appear lighter or darker, depending on the density of the material.
The dosage of X-ray radiation received by a dental patient is typically small (around 0.150 mSv for a full mouth series[1]), equivalent to a few days' worth of background environmental radiation exposure, or similar to the dose received during a cross-country airplane flight (concentrated into one short burst aimed at a small area). Incidental exposure is further reduced by the use of a lead shield, lead apron, sometimes with a lead thyroid collar. Technician exposure is reduced by stepping out of the room, or behind adequate shielding material, when the X-ray source is activated.
Once photographic film has been exposed to X-ray radiation, it needs to be developed, traditionally using a process where the film is exposed to a series of chemicals in a dark room, as the films are sensitive to normal light. This can be a time-consuming process, and incorrect exposures or mistakes in the development process can necessitate retakes, exposing the patient to additional radiation. Digital X-rays, which replace the film with an electronic sensor, address some of these issues, and are becoming widely used in dentistry as the technology evolves. They may require less radiation and are processed much more quickly than conventional radiographic films, often instantly viewable on a computer. However digital sensors are extremely costly and have historically had poor resolution, though this is much improved in modern sensors.

Great video I've learned so much. Im currently a dental assistant student, this is so helpful
The solution to my confusion. Thank you.
Edit: yes, these are really good instructions. Just tried it and I'm good already. Thanks a lot.
🤗
And fitted your tips into my brain cells
Max incisor +40 tip of nose
Canine +45 canine eminence
PM+30 second pm root
Molar+20 outer canthus of eye
Thanks❤
Very good explanation...thankyou doctor
You're welcome 🤗
Today I again saw your video and noted vertical angulation on a paper
Enjoyed! thankyou very much
Most welcome 🤗
Do a video on self developing xray also
Super madam
Thanks Ma'am
Nice explanation...rules are very perfectly said in single video
Thank you 😊
Thanks ma'am
Today I again saw your video
It is So helpful thank you
