Which condensation of gutta-percha, tip of the instrument is broken at apical third of canal. You would like to
1. Dissolve gutta-percha and retrieve the broken piece
2. Obturate remaining canal up to the point of obstruction, and observation
3. Do periapical surgery and apicectomy to remove broken piece
4. All of the above
Endodontics
Answer: 2
Finally, if the tip of the gutta-percha condensation instrument breaks in the
apical third of the root canal, the most common practice is to simply continue
with the obturation up to the point of obstruction. Attempting to dissolve the
gutta-percha or performing surgery to retrieve the broken piece may not be
necessary and can potentially cause further damage. Instead, the area is sealed,
and the body's natural healing processes are allowed to occur.
There is a real relationship between the incidence of fractured anterior teeth and the
1. Caries in those teeth
2. Hardness of the enamel
3. Hardness of the dentin
4. Protrusion of those teeth
Endodontics
Answer: 4
Explanation: Protruded anterior teeth are more susceptible to trauma and
fractures due to their position and exposure. This anatomical relationship
highlights the importance of considering tooth positioning in dental trauma
cases.
