Background: Odontomas are odontogenic tumors with a clinicopathological heterogeneity and a variable biological behavior. They usually are asymptomatic and can be discovered by routine radiographic investigations. This study aims to examine and compare intra- and postoperative consequences associated with use of piezosurgery and conventional rotary instruments for the removal of these oral lesions.
Methods: Clinical and histological data of 120 consecutive patients with a mean age of 22 years and 1 month (age range from 19 years and 1 month to 25 years and 3 months) with compound odontomas, diagnosed by biopsy, were assembled. Of a total of 120, 100 oral lesions were placed in the anterior region of the maxilla; of these, 50 were extracted through traditional rotary instruments (GROUP 1) and 50 with piezoelectric surgery (GROUP 2). The remaining 20 oral masses took place in the posterior area of the same bone; of these, 10 were extracted through traditional rotary instruments (GROUP 1a) and 10 with piezosurgery. (GROUP 2b). The piezoelectric cutting device was (Mectron Medical Technology) with MT1-10 insert, pump level 4, vibration level 7. Finally, pain, swelling, and surgical time evaluation were measured 24-48-72 hours after the intervention.
Results: As regards the mean time of surgery, in Group (1 and 1a) were 12 minutes, while in Group (2 and 2a) were 18 minutes. Regarding surgery, the osteotomy of the cortical bone was performed in all cases. As regards the measure of bone saved, calculated through a surgery gauge, it was greater of 3.2 mm in Group (2 and 2a) than in Group (1and 1a). The main of facial swelling in both Groups (1 and 1a) was 5.82 mm and 2.23 mm for the Groups (2 and 2a) immediately after surgery.
Conclusions: Piezosurgery produced less postoperative discomfort about the swelling. It is an effective technique in daily surgical practice, especially as regards the safety of soft tissues, bone, and nerves.

Objectives: The objective of this study is to evaluate the incidence and volume of contrast medium extrusion when activated with a laser and to compare these outcomes with those of other irrigation techniques.
Materials And Methods: Sixteen cadaver mandibles containing 116 single-rooted teeth were prepared using conventional rotary instrumentation. The teeth were randomly assigned to four irrigation groups: side-vented needle, sonic irrigation, laser activation at the orifice, and laser activation at the middle third of the canal.

Radix entomolaris (RE) characterized by an extra root in mandibular molars is a rare phenotype. When this condition coincides with complex root canal curvatures or S-shaped canals, root canal therapy (RCT) challenges arise. The present study presents three cases of RE along with complex root curvatures.

A polarimeter is a common but critical instrument for measuring the optical rotation of chiral compounds, ranging from the pharmaceutical to chemical industry, or even employed in monitoring chemical reactions for research purposes. Developing a portable polarimeter helps to transfer the measurements from the laboratory to on-site detection. Herein, we design a new portable polarimeter with a "hand-held" scale.

Introduction: This is a double clinical trial conducted to study the patient satisfaction and comfort during and after surgical removal of impacted mandibular 3rd molar using Piezo electric tips.
Material And Methods: Two groups of 25 each [14 (56 %) males and 11 (44 %) females] and [18 (72 % males and 07 (28 %) females] represented the Rotary and Piezo groups respectively with bilateral impactions. one side of the patient is operated by piezo and the other side by rotary instrument after a gap of 2-3 week between the procedures.

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.
