Background Naswar is a moist, non-chewable, and smokeless tobacco product ensconced in the buccal vestibule or floor of the mouth. Consumption of naswar is very popular in South Asia, especially Pakistan. This cross-sectional study compared the periodontal clinical parameters amongst mild, moderate, and severe naswar users. Methods 318 naswar users, categorized into three equal groups (n = 106) severe naswar users, moderate naswar users, and mild naswar users were drawn for this study. Bleeding on probing, pocking depth, gingival recession, and attachment loss were assessed using the UNC-15 probe and compared among the three groups of naswar users. Data analysis was done with the help of SPSS. Statistical significance was deliberated at p value ≤0.05. Results 28.9 ± 7.6 years was the mean age presentation. The mean % of bleeding on probing score was 61.95% in severe naswar users, 56.62% in moderate naswar users, and 51.23% in mild naswar users with a p-value of 0.001*. In severe, moderate, and mild naswar users the probing pocket depth (4-6mm) were 35.14%, 30.95%, and 23.21% respectively. 26.78% severe naswar users were having mean percentage for probing pocket depth (>6m) followed by moderate naswar users (17.26%) and mild naswar users (17.26%) with a significant p-value (0.001*). Clinical attachment loss (CAL) was 2.50 percent in light naswar users, 3.0 percent in moderate naswar users, and 4.25 percent in severe naswar users. Clinical attachment loss (CAL) was 2.50 percent in light naswar users, 3.0 percent in moderate naswar users, and 4.25 percent in severe naswar users. Severe naswar users had a high mean percentage of gingival recession (23.21%), whereas light 13.67 percent and moderate 14.88 percent naswar users had a smaller difference. Conclusions Clinical periodontal parameters were more worsen in heavy naswar users compared to moderate and light naswar users.

Background: Occupational hazards and risks are a common public health issue, especially when healthcare workers safety is concerned; they are on high risk of catching infections such like COVID-19. The possibility of cross-infection between dental practitioners and patients is significantly higher due to the close exposure of dental staff to patient oral environment. Aim: To assess the prevalence of SARS-COV-2 antibodies in dental workers working in the Peshawar Dental College and Hospital, Peshawar. Study Design: Cross sectional study Place and Duration of Study: Department of Orthodontics, Peshawar Dental College & Hospital, Peshawar from 1st January 2020 to 31st December 2020. Methodology: One hundred and thirty three dental workers were enrolled. The investigation was run to detect immunoglobulin G and M antibodies against the SARS-CoV-2-2. The aspirated aerosol and air was evacuated and dissipated into the atmosphere. Results: Mean age was 29.4±1.4 years and males were dominant 74 (55.6%) and male workers found greater with positive antibodies. The prevalence of SARS-CoV-2 antibodies was 33.0%. Proportionately dental assistants (20.5% vs 16.9%) and ancillary staff (20.5% vs 10.1%) had higher prevalence. Sore throat and body aches were more common in positive antibodies cases while travel history was found significantly associated with it (40.9% vs 25.0%, p-value, 0.05). Conclusion: High frequency of SARS-COV-2 antibodies was found in dental workers showing a high infection rate of COVID-19 in healthcare workers in local settings.

Aim: To determine the correlation between lip print, fingerprint form and blood groups that can be used for the identification of an individual among gender. Method: This cross-sectional study was conducted among 719 female and male participants with ages between 17-34 years from Bahria University Medical and Dental College. Patterns for lip and finger prints were collected along with the blood groups. SPSS v23 was used for statistical analysis. Frequency and percentages of the qualitative variables was calculated. The association of the variables was analyzed using Chi-square. Results: A total of 719 subjects, there were 327 males (45.5%) and 392 females (54.5%). Type I lip pattern was prevalent in 31.8% males followed by Type I’ in 27.6% females. The loop type of the finger print was observed in 165(50.5%) of males and 162(41.3%) females. The most common type of blood group was A+ in 27.2% in males while in females it was O+ in 29.8%. Conclusion: Individual parameters such as lip and finger prints along with blood groups can play an important role in personal identification of individual. In our study A+ blood group along with arch pattern of finger prints and Type I lip were most common patterns in males while in females Type I’lip pattern along with blood group 0+ and Loop pattern were common Keywords: Lip prints, Finger Prints, Cheiloscopy, Blood Groups, Forensic

OBJECTIVES: To determine the frequency of emergencies in patients with fixed and removable orthodontic appliances at tertiary care dental hospital. METHODOLOGY: A questionnaire was designed for this descriptive cross-sectional study to be filled by the clinician (L3/L4 FCPS resident) at the end of addressing every orthodontic emergency. Sampling was done under consecutive non-probability protocols. Descriptive statistics were applied to determine the frequency of different orthodontic emergencies, and Pearson’s chi-square test was applied to determine association of emergencies with gender and etiology of emergency (patient related vs operator related). Data was analyzed on SPSS version 20. RESULTS: A total of 175 patients reported with orthodontic emergencies. The sample comprised 38.3% males and 61.7% females. Most frequent orthodontic emergency reported was deboned brackets in fixed appliances, while the most common emergency in removable appliances was traumatic PNAM. A statistically significant association (Pearson’s Chi Square=4.74, Cramer’s V=0.165, p=0.029) was seen for removable and fixed appliance emergencies with males and females. CONCLUSION: Most frequent fixed appliance orthodontic emergencies were deboned brackets while for removable appliance emergencies were trauma due to PNAM. Emergencies with removable appliances were mostly due to the operator related factors, while in fixed appliances patient related factors were dominating.

Background: Dental plaque (biofilm) is a well-known contributor to the onset and progression of many dental illnesses. Plaque is a natural biofilm that develops on oral surfaces and contains a wide variety of organisms. As a result, it is critical to control plaque formation, particularly in the young population, by implementing effective preventive strategies. Objective: To assess and compare plaque removal efficacy of water flosser and string floss in patients. Study design: Randomized controlled trial Place and Duration of study: Department of Periodontology, Sardar Begum Dental College, Gandhara University from 1st March 2019 to 31st May 2019. Methodology: Seventy patients were enrolled. Patients were randomly allocated to one of two groups, group A (using dental floss) as the control group and group B (using waterpik) as the intervention group, using the lottery technique. Patients were randomly allocated to one of two groups, group A (control group), using dental floss and group B (intervention group), using waterpik utilizing the lottery technique. All participants were taught correct brushing technique utilizing the Modified Bass technique and manufacturer's instructions for using waterpik as well as normal flossing instructions for using Dental floss. Results: The mean age presentation was 34.23±6.78 years. The females were 42 (60%) males were 28 (40%). The mean percentage showed that those using water flosser with tooth brushing had low plaque score than using string floss with tooth brushing. The independent t test showed that water flosser is significantly more effective (p=0.001) in plaque reduction than conventional string floss. Conclusion: A water flosser coupled with hand brushing is more effective in eliminating plaque than string floss. Plaque removal was 20-30% higher in the group that used a water flosser.
