Intro
This technique is also known as intentional partial odontectomy.
What is coronectomy?
This is the PICOS question.
Population–patients who require surgical treatment to extract lower third molars and are at increased risk of IAN injury;
Intervention–surgery to perform the coronectomy or complete tooth extraction;
Comparison–a decreased risk for mandibular or LN injury, postoperative complications such as pain, infection and incidence of localized alveolitis and increased risk for reoperation, root migration, and extraction;
Outcome–prevents further IAN and LN injuries, as well as reduces the likelihood of other surgical complications (postoperative pain, incidence of infection, localized alveolitis, surgical reintervention, root migration, and root extraction);
Study design–observational studies (cohort and case control studies).
This author verified the accuracy of the data by cross checking.
Who is the third author?
This is the number of studies included in the analysis.
We are interested in coronectomy for this reason.
The most common complication of coronectomy.
What is root migration?
This was the main exclusion criteria.
What is studies where coronectomy or complete tooth extraction was performed on teeth other than the lower third molar?
These tools were used to assess risk of bias.
What is the Joanna Briggs Institute’s Critical Appraisal Checklist for Studies Reporting Prevalence Data and the Critical Appraisal Checklist for Case Reports?
The number of patients included in the comprehensive analysis.
What is 3,905?
This complication was rare in both coronectomy and complete extraction.
What is lingual nerve injury?
This group of medically complex patients is contraindicated from this procedure.
Who are immunosuppressed, uncontrolled diabetic patients undergoing chemotherapy or radiation therapy?
This was the primary variable in the quantitative comparison.
What is the incidence of IAN injury?
This test was used to evaluate statistical heterogeneity.
What is the I2 or inconsistency index test?
Coronectomy reduces the incidence of sensory loss of the IAN by this odds ratio. Please advise if this is statistically significant or not.
What is 0.14 (95% CI 0.06 to 0.30)?
Sencimen et al found this in a 2010 study.
What is that the group that underwent coronectomy with endodontic treatment had high infection rates and required extraction of seven of the eight roots. In contrast, in the control group, only one extraction
was performed.
Intentional partial odontectomy was proposed by Ecuyer and Debien in this year, incidentally the title of a well-known book.
What is 1984?
These were the main outcomes. (Name four.)
1. frequency of injury to the IAN and LN
2. postoperative pain
3. infection
4. localized alveolitis
5. need for surgical reintervention
6. root migration
7. extraction
This many articles were excluded from the review.
The risk of reintervention is high in coronectomy. This is the odds ratio (please include CI).
What is OR: 5.38; 95% CI: 1.14 to 25.28?
These are significant factors affecting root migration.
What are age and sex?
Younger and female patients show greater migration of the root remnant.
This procedure is considered unnecessary during coronectomy.
What is treatment on the exposed pulp?
All of the included studies were these two types of studies.
What are case control and cohort?
This many of the included studies had a high risk of bias.
What is none?
No relationship was found for these outcomes.
What are sensory loss of the lingual nerve and infection?
What is 0.047mm?
