Urinary Tract Calculi VI: Surgical Management

222
Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

Summary

Root canal treatment (RCT) during coronectomy does not reduce postoperative infections. Retained M3 roots after coronectomy do not require RCT, as submersion prevents infection.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Endodontics
  • Infectious Disease

Background:

  • Coronectomy is used to prevent inferior alveolar nerve injury during mandibular third molar (M3) extraction.
  • Concerns exist regarding infection risk from submerged M3 roots with exposed pulp.

Purpose of the Study:

  • To determine if concurrent root canal treatment (RCT) reduces postoperative infections after M3 coronectomy.
  • To review studies on pulpal physiology related to coronectomy.

Main Methods:

  • A comprehensive review of controlled studies comparing M3 coronectomy with and without concurrent RCT.
  • Inclusion criteria: English, human studies, reported postoperative infection outcomes.

Main Results:

  • Only one relevant study was identified.
  • Postoperative infection rates were 87.5% with RCT and 12.5% without RCT.

Conclusions:

  • Concurrent RCT at the time of coronectomy does not decrease postoperative infection frequency.
  • RCT is unnecessary for retained M3 roots after coronectomy.
  • Intentional root submersion does not necessitate RCT.
