Comparison between Different Combinations of Alendronate, Platelet-rich Fibrin, Hydroxyapatite in Bone Regeneration in Endodontic Surgeries Using Cone-beam Computed Tomography.

Aim: To compare different combinations of alendronate, platelet-rich fibrin (PRF), and hydroxyapatite in bone regeneration in endodontic surgeries using cone-beam computed tomography (CBCT).

Methods And Subjects: During this study, 28 patients were selected who were found to have pathology in the periapical area in the anterior region, The study subjects were categorized into four categories, each consisting of seven subjects, Category one-there was no placement of any material; category two-PRF; category three-hydroxyapatite along with PRF; category four-alendronate along with PRF, Root canal treatment followed by endodontic surgery in each patient was carried out, Volumetric analysis of the lesions was carried out before surgery and 12 months after surgery using CBCT, Analysis of variance (ANOVA) test and Tukey test were used for statistical analysis.

Results: There was a maximum change in the volume of lesions in the study subjects in which PRF was used along with hydroxyapatite in comparison to other combination of materials, There was no significant difference when PRF was placed along with alendronate in comparison to study subjects when PRF was placed alone, The difference was not significant when PRF was placed in defects of bone in comparison to study subjects when no materials were placed in the defects of bone.

Evaluation of two socket healing procedures with and without mesenchymal stem cells: A comparative study.

Aims And Objectives: Successful preservation of the edentulous ridge after extraction may eliminate or reduce the need for ridge augmentation procedures. It is proved that grafting of fresh extraction sockets with bone grafts promotes ridge preservation. An objective method of maintaining height and width of alveolar ridge using mesenchymal stem cells (MSCs) seeded on collagen membrane was implemented in this study.

Aerobic microbiology and culture sensitivity of head and neck space infection of odontogenic origin.

Context: Head and neck space infections source, age, gender, tooth involved, fascial spaces involved, microbiological study of aerobic flora, and antibiotic susceptibilities.

Aims: The aim of the present study is to identify causative aerobic microorganisms responsible for deep fascial spaces of head and neck infections and evaluate the resistance of antibiotics used in the treatment of such.

Settings And Design: Prospective study in 100 patients.
