Teeth

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

Area of Science:

  • Endodontic Surgery
  • Dental Materials Science

Background:

  • Conventional endodontic therapy achieves success in 80-85% of cases, with failures often manifesting after one year.
  • Indications for surgical retreatment include persistent pain, drainage, mobility, or enlarging radiolucent areas.
  • Salvaging treated teeth with existing restorations is crucial for patient care.

Purpose of the Study:

  • To evaluate the efficacy of ultrasonic root end preparation in periapical surgery.
  • To assess the impact of piezoelectric devices on apical preparation and sealing.
  • To determine if advanced techniques improve surgical outcomes in endodontic retreatment.

Main Methods:

  • Utilized ultrasonic piezoelectric devices for root end preparation in periapical surgery.
  • Focused on achieving controlled apical preparation and effective sealing of isthmus areas.
  • Compared outcomes with conventional surgical preparation methods.

Main Results:

  • Ultrasonic devices enable more controlled apical preparations.
  • Enhanced ability to prepare and seal complex isthmus areas between canals.
  • Reduced likelihood of malpositioned root canal fillings, improving procedural precision.

Conclusions:

  • Ultrasonic root end preparation represents an advancement in periapical surgery.
  • This technique offers greater precision, potentially leading to more successful endodontic retreatment outcomes.
  • The use of piezoelectric devices can improve the management of complex root canal anatomy during surgery.
