Radiation therapy is an important component in management of oral cancer. As a result, various uninvolved structures like salivary glands, oral , dentition, and jaws receive significant doses of radiation. Radiotherapy for oral cancer typically involves total doses of 6,000–7,000 , delivered in daily fractions over 6–7 weeks and is known to cause a number of oral complications. These include oral , oral pain, , increased risk of dental caries, reduced mouth opening, and . The aim of the study isto evaluate and identify the incidence rates of oral complaints following radiotherapy for oral cancer. Data samples required for study were taken from hospital records. All the collected data were cross verified and compiled together in sheet. Compiled data were statistically with help of SPSS software. In this study, a total of 51 patients of oral cancer underwent radiotherapy as a part of their treatment regimen. Higher percentage of patients reported back with no oral complaints of 58.82%. With an increase in age group, more patients had oral complaints after radiotherapy treatment, with p value of 0.114. More males had oral complaints compared to female patients with p value of 0.424. Within the limitations, it is significant that the maximum number of patients who underwent radiotherapy returned without any oral complaints.

Local anesthesia is more commonly used in dentistry to facilitate a painless treatment experience for a patient during surgical procedures involving bone and soft tissue. Hence, to facilitate a painless treatment experience for a patient should know ideal requirements before administering a dose. This study aims to assess the mastery of local anesthesia by students by evaluating the amount used for single tooth extraction. In this retrospective study, data were obtained from hospital records. The study aimed to evaluate the mastery of local anesthesia by students by evaluating the amount used for single tooth extraction. The data was obtained from the department of oral and maxillofacial surgery from June 2019 - April 2020. A total of 2100 patient details were evaluated. The current study is done in a university setting. Ethical approval was obtained. The collected data were tabulated and statistically analysed using SPSS software (Version 21: IBM Corporation NY USA). Descriptive statistics (frequencies and percentages) were calculated to explore the general features of the data. Pearson chi square test was done to statistically analyze the data. Patients of all age groups were included in this study. Around 14.5% of the patients were below 30 years, 40.7% of the patients were between the age of 30-50 years, and 55.2% of the patients were above 50 years old. Around 95.9%, 3.1%, 0.9% and 0.1 % were administered with 2, 3, 4 and 5 ml respectively, of which 55% and 45% were male and female patients respectively. Within the limits of this study, 95.9% were administered with 2ml for extracting a single tooth. 95.9% use ideal recommended dose and concentration for performing a single tooth extraction.
