What is chloroform used for in endodontics? ›

Chloroform is used in endodontics for solving gutta-percha points and for removal of gutta-percha from root canals in re-treatments,¹⁰ but in this case it was used as anesthetic agent by being injected into root canal of the maxillary first molar.

Root canal overfill is a concerning issue that can lead to significant complications for patients undergoing endodontic treatment. This problem occurs when dental professionals inadvertently use excessive filling material during the procedure, which may result in damage to surrounding tissues and nerves.

Why Endodontists Use A Rubber Dam During A Root Canal. It isolates the tooth being worked on from bacteria in your saliva. This is important for maintaining a sterile environment for the tooth. It prevents water, debris, or anything else from going down your throat.

Eyepiece. The power of eyepiece determines magnification. Eyepieces are usually available in powers of 10×, 12.5×, 16×, and 20×. To adjust the accommodation of the lens of the eyes, diopter settings should range from −5 to +5.

Chloroform is a solvent commonly used for removal of root filling materials. It is the fastest and most efficient solvent for softening of gutta-percha. Other solvents have also been tested but have shown lower efficacy for this purpose [ 3 ].

Chloroform in dentistry is one of the most widely used solvents for plasticizing gutta percha points during their removal in retreatment cases. Despite being toxic and carcinogenic, chloroform has been deemed acceptable when under careful and controlled use.

The classic “Endodontic Triad” is founded on the 3 pillar principles of cleaning, shaping, and packing. More specifically, the historical triad was described as debridement, sterilization, and obturation.

Out of 250 teeth, a higher percentage of failure was noted in molars (67.6%), followed by premolars (14.0%), incisors (12.8%), and the least in canine (5.6%). The study exhibited multi-rooted teeth with a maximum percentage (74.4%) of failure than those with single roots (25.6%). In the Noboru Imura et al.

Successful endodontic treatment depends on proper shaping, disinfection, and obturation of root canals. Filling materials should completely fill the root canal space without exceeding the anatomical apex. Overfilling may occur when the filling material extrudes into the periapical tissues beyond the apex.

According to the American Association of Endodontists position statement, ''Tooth isolation is the standard of care; it is integral and essential for any nonsurgical endodontic treatment. only the dental dam isolation minimizes the risk of contamina- tion of the root canal system by indigenous oral bacteria'' (8).

Why didn t my dentist use a rubber dam? ›

Even though the dental dam can be a great tool for certain procedures, there are some obstacles to using them. Some dental professionals feel reluctant to use dental dams because their placement can be difficult. They also require extra time and money. And some dentists don't have the proper training to use them.

When you have a dental dam in place, you will breathe through your mouth around the material's sides and nose. If you have latex allergies, let the practitioner know to ensure that you get a non-latex dental dam. You will be more comfortable during and after the procedure by having a nonreactive rubber dam.

Zipping is best described as a ledging effect that simply happens to be directly at the apical foramen. In a zipped canal the gouging effect of the file upon the dentin occurs at the canal terminus at the external surface vs. the gouging effect internal to the canal system in a ledged situation.

On many occasions, and particularly when using the bisecting angle technique, superimposition of the zygomatic process of the maxilla over the root apices of molar teeth occurs, resulting in the characteristic arch-like radiopacity which hinders radiographic interpretation.

Using loupes improves the quality of dental students' tooth preparations, visual acuity and ergonomic practices in endodontic and prosthodontic procedures.

Chloroform is used as an extraction solvent for fats, oils, greases, rubber, waxes, gutta-percha, resins, lacquers, floor polishes, artificial silk manufacture, gums and adhesives. It is utilised as an industrial solvent in the extraction and purification of some antibiotics, alkaloids, vitamins and flavours.

Chloroform is a trihalomethane that serves as a powerful general anesthetic, euphoriant, anxiolytic, and sedative when inhaled or ingested, for this reason, Chloroform was used as an inhalational anesthetic between the 19th century and the first half of the 20th century.

It is a useful clearant for special cases such as decalcified hard bone, which will be left relatively soft after infiltration. One serious disadvantage is that chloroform attacks rubber and plastics so it cannot be used on most modern automatic tissue processors, since the seals will be destroyed.
