Implementation of machine learning models as a quantitative evaluation tool for preclinical studies in dental education.

Purpose And Objective: Objective, valid, and reliable evaluations are needed in order to develop haptic skills in dental education. The aim of this study is to investigate the validity and reliability of the machine learning method in evaluating the haptic skills of dentistry students.

Materials And Methods: One-hundred fifty 6th semester dental students have performed Class II amalgam (C2A) and composite resin restorations (C2CR), in which all stages were evaluated with Direct Observation Practical Skills forms.

A retrospective comparative study of hemorrhoidal artery ligation versus ligasure hemorrhoidectomy for the third degree hemorrhoidal disease.

Background: Hemorrhoidal disease (HD) is the most common disease of the anorectal region. Excision of pathological hemorrhoidal structures by providing bipolar energy transfer with Ligasure, which is basically an electrosurgical device, is one of the treatment methods Ligasure hemorrhoidectomy (LH). In another method applied for the first time by Morinaga, the vascular plexus is provided by Doppler-guided ligation of the hemorrhoidal arteries (ADHL).

Do we need mesh fixation at the laparoscopic hernia repair?

Objective: With the development of laparoscopic treatment, widespread use of laparoscopy has become inevitable for the treatment of inguinal hernias, which is one of the most common ailments in surgical practice. Fixing or not fixing the mesh during laparoscopic repair remains a debate. In our study, we aimed to compare patients with and without mesh fixation in terms of postoperative pain, recurrence, complications, hospitalization and return to social life.

A comparison of off-pump and on-pump coronary bypass surgery in patients with low EuroSCORE.

Background: The aim of the present study was to evaluate and compare postoperative short-term, mid-term and long-term outcomes of coronary artery bypass surgery performed with or without cardiopulmonary bypass in patients with a low European System for Cardiac Operative Risk Evaluation score.

Methods: A retrospective analysis of 478 consecutive low risk patients undergoing coronary bypass surgery between January 2002 and December 2007 was performed. Of these patients, 83 cases had undergone on-pump and 395 cases had undergone off-pump coronary bypass surgery.
