Periodontics and Orthodontics often relates to a symbiotic relationship. Corticotomy was introduced as a surgical procedure to shorten orthodontic treatment time. This procedure involves the removal of cortical bone that strongly resists orthodontic force in the jaw. Though there are numerous studies done in the literature on PAOO, this review mainly focuses on the various comparative studies employed under this procedure. On the other hand, various modifications of this method such as minimally invasive techniques have been introduced to reduce the patient’s discomfort due to surgical intervention and complications after surgery. The present review focuses on the history of corticotomy, its mechanism of action, and various comparative studies done under PAOO.

Introduction: Achieving regeneration of the lost periodontal structures after surgical approach plays a major role. This healing can be interrupted due to the presence of invasive bacteria which is present in the periodontal tissues. Aim: To compare laser-assisted and conventional flap surgery using microsurgical instruments and under surgical operating microscope with hydroxyapatite graft in the treatment of intrabony defects. Materials and Methods: This prospective randomised split-mouth clinical study was conducted in Department of Periodontology at Vishnu Dental College, Bhimavaram, Andhra Pradesh, India, from June 2020 to December 2021. A total of 24 bilateral intrabony defects were selected for the study. Control sites (n=12) received the graft after conventional open flap debridement. In the test group (n=12), graft placement was done followed by laser irradiation with diode laser (980 nm, power: 3.0 W; frequency 2.5 KHz) for 30 seconds. The entire flap surgery procedure was performed under Surgical Operating Microscope (SOM). Clinical parameters such as plaque index, gingival index, probing depth, relative attachment level, were assessed at 3 months and 6 months. Healing index was assessed after 7 days of surgery. Radiographic parameters were assessed at baseline and 6 months using Cone Beam Computed Tomography (CBCT). Descriptive statistics, Independent samples t-test, repeated measures analysis of variance and Paired t-tests were used in data analysis. Data were analysed using Statistical Package for Social Sciences (SPSS) version 20.0 software. Results: Intragroup comparison showed statistical significance in all clinical and radiographical parameters (p-value<0.001). Intergroup comparison between the test and control group did not show any statistical significance in terms of plaque index, gingival index, relative Clinical attachment level, probing depth (p-value≥0.05). Intragroup comparison of the depth of defect was statistically significant in both test (p-value=0.011) and control groups (p-values=0.002). Intergroup comparison did not show any statistical significance in linear bone fill (p-value=0.1). Intergroup comparison did not show any statistical significance in defect angle (p-value=0.773). No statistical significance was obtained in percentage fill (p-value=0.074). Intergroup comparison did not show any statistical significance in the clinical and radiographical parameters. Conclusion: The additional laser irradiation at the test site did not exhibit any significant benefits in the bone regeneration. All the outcomes were similar in test and control group.

Preservation of periodontal health after periodontal therapy is paramount for the complete elimination of periodontal diseases. In most of the Dental Schools, recall appointments are considerably low, and in particular, to the Department of Periodontics, the compliance to recall visits by the patients diagnosed with periodontal disease is still inadequate. Faculty from the Department of Periodontics framed new criteria to follow in the comprehensive clinics by the postgraduate students. The criteria include communication, intraoral examination skills, and professionalism toward dental patients. Faculty in each comprehensive dental clinic observed the clinical encounters of postgraduate students with patients and provided the feedback. The study conducted from May 2018 to April 2019, and the patients attended were 1164 of 1544. Unattended patients were 380 of 1544. Effective evaluation of the feedback provided by faculty and communication with both the postgraduate students and unattended patients resulted in further improvement in recall, that is, 151 of 380 patients. Reframed criteria, direct observation of the postgraduate students by faculty during patients interaction, assessment of feedback forms, and immediately modifying the student’s way of communication allowed maximum recall visits to the Department of Periodontics.

Dental students, especially postgraduate students present a higher risk of getting infected because of their close contact with the patients during this pandemic. The objectives of the study include (a) the reasons for postgraduate students’ altered emotional status during coronavirus (COVID-19) infection. (b) To assess the kind of infection protocols adopted. (c) To assess the impacts of postgraduate students’ emotional status on treating patients with periodontal problems during the COVID-19 lockdown period from March 2020 to December 2020. The emotional status of postgraduate students was assessed in 2 phases that are at the initial phase of COVID infection and lockdown and the second phase when the lockdown was prolonged. Questionnaires were distributed to the Postgraduate students of periodontics all over India to assess their level of awareness of COVID infection, type of infection control measures followed during the pandemic period, as well as the outpatient turnout during the lockdown period. Results of this study stated that more than 80% of students addressed the decline in the number of patients to surgical clinics, 76.3% of postgraduates were worried about themselves and their families due to the pandemic situation. Surprisingly, 74.3% of them even worried about losing their expertize or skills due to a long lockdown period. Dental postgraduates all over India are willing to treat their patients during the period of a pandemic but in strict compliance with infection control guidelines. This study assessed the emotional responses of the postgraduates during the pandemic through the questionnaire and concluded that all the professionals are ready to resume their clinical activities with adequate guidelines provided.
