Background: Inflammatory complications are the most prevalent problems after surgical extraction of mandibular third molars. The main options for prevention are prophylactic antibiotics usage before surgery or in the postoperative period; a method of postoperative management of a tooth socket, implying healing by primary or secondary closure. Each of the postoperative management types has advantages and disadvantages.
Objective: The aim of the study was to compare complete suturing versus iodoform gauze packing of tooth socket for prevention of inflammatory complications after mandibular third molar removal.
Material And Methods: A retrospective cohort study was performed. The medical records of 273 patients who underwent mandibular third molar extraction for orthodontic indications were analyzed. Data of 100 patients were included, in 50 cases the postoperative management was carried out using iodoform packing, in other 50 cases complete suturing was performed. Depending on the type of data and distribution, we used the chi-squared test, Fisher's exact test, Student's -test, Mann-Whitney U test. A <0.05 was needed to achieve statistical significance.
Results: Alveolitis developed in 8 % cases of iodoform gauze packing and 34% cases of suturing. The differences are statistically significant (=0.003). The total rehabilitation period (days) in patients with no alveolitis using iodoform gauze packing was 8 (7; 31) (Me (Q1; Q3)), using complete socket suturing was 7 (7; 8) (Me (Q1; Q3)), the differences are statistically significant (=0.003).
Conclusion: The best option for the prophylaxis of alveolitis after surgical extraction of mandibular third molar is secondary closure using iodoform gauze packing. However, in the cases with no alveolitis when complete suturing was performed, healing occurred much faster, which justifies the development of an alternative method for third molar socket healing.

Background: Opioids are still being prescribed to manage acute postsurgical pain. Unnecessary opioid prescriptions can lead to addiction and death, as unused tablets are easily diverted.
Methods: To determine whether combination nonopioid analgesics are at least as good as opioid analgesics, a multisite, double-blind, randomized, stratified, noninferiority comparative effectiveness trial was conducted, which examined patient-centered outcomes after impacted mandibular third-molar extraction surgery.
Age estimation at 18-year threshold: comparing Demirjian and Cameriere's methods for Thais.

This study aims to compare the accuracy of Demirjian's and Cameriere's methods in determining adult age at the 18-year threshold using mandibular third molars in the Thai population. Panoramic radiograph images of 504 healthy subjects aged between 14 and 23 years were retrospectively collected. The developmental stages of mandibular third molars were evaluated using Demirjian's method, while the maturity index of mandibular third molars (I3M) was assessed using Cameriere's method.

Do instrument kinematics and the apical preparation limit influence canal disinfection and bacterial extrusion?

Department of Endodontics, University of Southern Santa Catarina (UNISUL), Palhoça, Santa Catarina, Brazil.
This in vitro research assessed the influence of the instrument kinematics (rotary and reciprocating) and the apical preparation limit on the root canal disinfection and apical bacterial extrusion. After 21 days of Enterococcus faecalis biofilm formation in 72 mesial root canals of mandibular molars, the root canals were distributed into 2 groups (n = 36) according to the systems used for preparation: ProDesign S and Reciproc. The groups were redistributed according to the limit of apical preparation (n = 11): (a) 1 mm up to the apical foramen (TL-1); (b) at the apical foramen (TL = 0); (c) 1 mm beyond the apical foramen (TL + 1).

Article Synopsis
- The extraction of a submandibular-displaced mandibular third molar root is challenging for surgeons due to its closeness to important structures like the lingual nerve and sublingual artery.
- Preoperative imaging helps locate the root, but real-time synchronization is tough because of the mandible's moving nature.
- This study highlights the successful extraction of a residual root using a magnetic navigation system, resulting in a minimally invasive procedure with no complications or major issues reported postoperatively.
