Objective: To evaluate the outcome of first molar extraction in patients with crowding.
Methods: Totally 22 patients (8 males and 14 females) from Clinic of Orthodontics, SUN Yat-sen University School of Stomatology with crowding were collected. The patients were aged 11 years 3 months to 26 years 8 months (mean age 16 years 6 months). All of them treated with 1 to 4 first molar extractions.
Results: The average duration of orthodontic treatment was 18.5 months. Normal overjet and overbite was achieved. Good functional occlusion was established.
Conclusions: Patients with severe crowding could be successfully treated with first molar extraction.

Purpose: This study aimed to analyze changes in anxiety and comfort levels at each perioperative stage during third molar extraction under single-agent intravenous midazolam sedation, and to clarify how these conditions at each perioperative stage affect postoperative satisfaction.
Patients And Method: 115 who requested extraction of 1 ~ 4 third molars under single-agent intravenous midazolam sedation were targeted. These patients were administered a questionnaire survey one week after surgery.
Comparative Evaluation of Canal Transport and Centralization Between ProTaper Next and XP-endo Shaper Systems Using CBCT Analysis: An In Vitro Study.

This study compared the apical transportation and centering ratio of ProTaper Next (PTN) and XP-endo Shaper (XPS) nickel titanium (NiTi) rotary files in curved root canals using cone beam computed tomography (CBCT). The current in vitro study involved the mesiobuccal canals of mesial roots in 44 extracted mandibular first molars that exhibited apical curvature ranging from 10° to 30°. Two experimental groups were randomly formed from the teeth ( = 22) and subjected to instrumentation with PTN and XPS.

Background: This study aimed to establish a model for predicting the difficulty of mandibular third molar extraction based on a Bayesian network to meet following requirements: (1) analyse the interaction of the primary risk factors; (2) output quantitative difficulty-evaluation results based on the patient's personal situation; and (3) identify key surgical points and propose surgical protocols to decrease complications.
Methods: Relevant articles were searched to identify risk factors. Clinical knowledge and experience were used to analyse the risk factors to establish the Bayesian network.
Comparison of smart burs and chemo-mechanical caries removal systems in primary molars - A systematic review and meta-analysis.

Article Synopsis
- Smart burs and chemo-mechanical caries removal (CMCR) systems are alternative techniques for cavity preparation, but existing studies show mixed results regarding their efficacy, efficiency, and patient comfort.
- This systematic review analyzed in vivo studies comparing these methods, excluding lower-quality sources and conducting a thorough risk of bias assessment on the included studies.
- The analysis revealed that, although 154 studies were initially reviewed, only a few were suitable for meta-analysis, showing no significant difference in clinical efficacy between CMCR systems and smart burs.

This retrospective longitudinal outcome study comparing orthodontic extraction modalities, including extraction of maxillary first or second molars, aimed to compare the three-dimensional tooth movement of maxillary canines (C), premolars (P1, P2), and molars (M1, M2) in Class II division 1 malocclusion treatment with fixed appliances. A sample of 98 patients (mean age 13.20 ± 1.
