The pulp is removed, and the interior of the tooth is cleaned and sealed during root canal treatment. Root canals are dreaded by many people because they are considered to be painful. The following are indicators of pulpal damage, color changes, swelling, thermal sensitivity, and pain in the gums. The pulp gets inflamed or diseased when it becomes infected, then RCT or extraction is needed to eliminate the inflamed or infected tissue and heal that particular region. The questionnaire was circulated to the sample population through a Google Docs link. Pie charts with a frequency table were created when the survey data were acquired. The Chi-square test was used to evaluate the connection using the SPSS software. Eighty-four percent of people are aware of RCT and what it is intended for and 80% of the participants themselves have undergone endodontic treatment. Most of the South Indian population were aware of root canal treatment and have undergone an RCT procedure.

Taking an online course requires more motivation and self-discipline than taking a classroom-based course. One or more teachers and peers may keep a student responsible for their course work in a classroom. Online classes, on the other hand, enable us to set our own targets, chart our success, and follow deadlines. An awareness-based, self-administered questionnaire was created. The target audience for the study received a link to the questionnaire through Google Docs. The participants were given a thorough explanation of the survey's objectives. Pie charts with a frequency table were created after the survey findings were known. A Chi-square test was used to examine for associations in the statistics, and a P = 0.05 was considered statistically significant. The overall satisfaction level with online classes among students was, 57% were not satisfied with online classes, 31% were satisfied, and 12% were extremely satisfied. Most commonly students were not satisfied with both genders. However, majority of the females were not satisfied. This difference was statistically significant (Pearson's Chi-square value: 1.999, df = 2, P = 0.368 (>0.05) – significant). Eighty percent of the students have faced difficulties while attending online classes. However, 92% of the students have agreed that the technology helped them to attend their online classes.

The coronavirus disease 2019 (COVID-19) pandemic—and the social distancing measures that many countries have implemented—have caused disruptions to daily routines. Mental health support and follow-up should be provided even six months after the release from isolation for those individuals with prior vulnerable mental health status. The main aim of the study is to create awareness and knowledge about COVID – 19 and its impact on the mental health of the public. The self-administered design was designed based on awareness. The questionnaire was distributed through google docs link to 100 numbers of the study population who were in lockdown irrespective of age. Methods of representation of each output variable were represented in the pie chart form. The measure that was taken to minimize the sampling bias was that the validity that was checked both internally and externally. The result was statistically analyzed using SPSS software. The participants were explained about the purpose of the study in detail. From the above Survey conducted, 58% of the total 100 participants' mental health being affected due to lockdown imposed due to COVID -19. This COVID 19 has created stress, anxious and nervous situations for 47% of the total participants. Educated people and health professionals are aware of this infection; they take possible preventive measures. They understand the importance of social distancing. So this lockdown is not affecting their mental health.

Introduction: Endodontic emergencies are characterized by violent or disabling pain. The management of these emergencies requires a precise diagnosis and an emergency act with or without a prescription. Endodontic emergency treatment options have sparked a lot of debate. As a result, dentists must have sufficient experience and expertise about appropriate care procedures in order to effectively handle these cases. Aim: The main aim of the study is to assess the awareness level for managing the endodontic emergencies. Materials and Method: Based on knowledge, a self-administered questionnaire was developed. The questionnaire was distributed to the sample population through a Google Docs link. The participants were explained about the purpose of study in detail. Once after the results of the survey were obtained, pie charts with a frequency table were prepared. The statistics done using SPSS software, chi square test was done to check the association and a p value of 0.05 and lesser was said to be statistically significant. Results and discussion: 88 % of the population have handled endodontic emergency cases but the treatment options which were given by the participants are not the same as the standard procedures.

Neurolink is the work product from Musk in the year 2016, which was about to develop an implantable and high-brain -computer interface (BCI). The treatment for the sensory and motor activities Brain-machine Interface (BMI) is also used for the treatment of neurological problems. The aim of this review is to explore some detailed information regarding the recent advances in Neurolink project - the benefits, merits as well as the demerits it has. This concept that is a project with neuro link was completely a new idea, and the modern world needed equipment like this, to help people with neurological disorders since the turn of the century. This new invention has a three stated goal, the first and most predominant one was for treating any kind of neurological disorders, and the second one is for the people who met with an accident and last and final was to create BMI. For example, a paralyzed person can use a BMI to move a mouse cursor or a robotic arm. Such options let them retain more independence. This idea of developing BMI of Musk was completely a new idea, and it was positive towards people, and cost-effective means of delivering neurosurgical care to underserved areas are the conclusions from the initial experience of this new project. This review is an attempt to update the recent advance of Neurolink project; further research is the need of the hour to know about its complete use for human beings.
