Objective: To assess the vertical forces produced during canal shaping by the Reciproc Blue (RB) and Reciproc (R) systems. Place and Duration: In the Operative Dentistry Department, Altamash Institute of Dental Medicine Karachi for one-year duration from January 2022 to December 2022. Methods: A total of 32 maxillary premolar teeth were selected, each with two distinct constricted and straight canals. Every tooth was positioned in a standing position on a platform attached to a force analysing device after access cavity preparation (M5-20 Advanced Digital Force Gauge; Mark-10 Corporation, NY, USA). Until the K file size was up to 15, the glide route was prepared manually. Then, using an R25/RB25 file, all of the groups' canals were completely shaped (0.08 taper, size 25). The canal was shaped with a mild and steady pressure on the file that produced a gradual, 2 mm amplitude "in-and-out" movement. It took three attempts for the file to successfully reach the WL. The canal was irrigated and recapitulated with sodium hypochlorite (1%) solution following each insertion. The Student's t-test was used to analyze the shaping time. The Mann Whitney test was applied to analyse the upward and inward peak forces. With a 95% level of confidence, SPSS software was used for all statistical analyses. Results: A single file was inserted into each root canal successfully three times for shaping till the WL achieved. With each additional file insertion, the overall real-time force increased in each group grew. The R group displayed lower peak forces in comparison to the RB group in the 3 insertions, and both groups inward peak forces varied from 1.76 to 8.64 N. (P<0.05). Complete canal shaping of the RB and R systems took an average of 24.30±3.98 s and 21.91±3.56s, respectively (P>0.05). During canal shaping in this experiment, no file fracture occurred. Conclusion: The forces generated during canal shaping were influenced by the blue heat treatment. Higher inward peak forces were higher in the RB file than the R file. Keywords: Root canal preparation, Endodontics, vertical force and shaping time.

Aims: To ascertain the prevalence of dental caries using DMFT scores, to characterize the oral health status and associated factors of patients attending the Nasirabad Rural Health Center Dental Clinic, and to develop tools and strategies for collecting data for rural oral hygiene statistics. The district collects baseline data to aid in the improvement of dental health initiatives in rural Sindh. Design: From August 2018 to May 2019, convenience sample research was undertaken. Patients aged 15 or older met the requirements. Adult Oral Health Assessment Form (WHO) was used to gather data on oral health examinations. The Nasirabad Rural Health Centre's Dental Unit used a basic mouth mirror and an explorer to interview and clinically examine all subjects. The tools are sterile. On proformas collected biographic and DMFT data. Microsoft Excel 2016 was used to enter and analyses data. The sample comprised both genders and ages. In this study, dentists calculated the mean DMFT score. Items from an adult oral health questionnaire were modified and categorized as Demographics and Clinical evaluation. Demographic data included the patient's age and gender. The dentition was examined for healthy, decaying, missing, and filled teeth (Ft). Results: Microsoft Excel was used to organize and analyses the data. Males made up 41% of the population, while females made up 59%. Caries prevalence was 96 percent overall, with 204(22%) having a low caries status, 250(26%) having a moderate caries status, and 451(48%) having a high caries status. The mean DMFT score was 11.1424017, the standard deviation was 8.0937, and the Significant Caries Index (SiC) was 20.99363057 based on the DMFT value and the number of participants. Conclusion: The research population had poor oral hygiene and dentition. The mean DMFT Score was 11.1424017 and the frequency of dental caries was 96%, with a female bias. Pakistan is a poor nation with little dental health resources and awareness. Providing public oral health education and motivation, water fluoridation, and adopting newer research-based treatments of remineralization of dental caries must be prioritized. It is a major job for the health profession and the government. This issue is critical for dental health and requires immediate care.

Dental abrasion (DA) is an erosive activity that wears away the surface of teeth. Due to the use of abrasive dentifrices and incorrect brushing techniques, it is a multifactorial phenomenon. Objective: To assess the severity of dental abrasion in association with oral hygiene behaviors. Methods: A total of 278 undergraduate students aged 18 to 25 years were enrolled in this study who were having abrasion of permanent dentitions. Mouth mirror and CPITN probe were used to detect abrasion on the labial surface of front teeth and conducted a questionnaire. The Smith and Knight's Tooth Wear Index was used to measure the severity and frequency of dental abrasion in the patients. SPSS version-22 was used to analyze the data. Results: From 278 participants, females were 163 (58.6%) and males were 115 (41.4%). Majority 132 (47.5%) were using medium type of brush, most of the cases 122 (43.9%) brushing twice a day. About 107 (38.5%) using brushing methods in combination, 137 (49.3%) were using brush for 1-2 minutes. Tooth sensitivity was reported in 133 (47.8%) of the cases. Out of all, DA was found in 160 (58%) of the cases. According to severity, minimum loss of surface characteristics was in 220 (79.1%). A highly significant association (p=<0.001) was found between the type of brush and dental abrasion. A non-significant association (p=0.816) was found between both frequencies of brushing and dental abrasion. Conclusions: Brushing parameters did not affect abrasive lesions. Further study and long-term follow-up are required to distinguish oral hygiene routines from tooth abrasion

Introduction: Chronic periodontitis is the inflammation of the gingiva extending into the supporting structure of teeth. Periodontal disease is characterized by loss of clinical attachment due to destruction of the periodontal ligament and loss of the adjacent supporting bone eventually leading to tooth loss. Obesity is unusual or unnecessary fat deposition that may harm health. A number of hypotheses for biological reactions among obesity and periodontal disease have been anticipated. Objectives: To determine the frequency of ideal weight, overweight and obese patients in dental outdoor of FMH Pakistan. Study Design: Cross-Sectional Study. Setting:  Medical Outdoor at Tertiary Care Hospital in Pakistan. Period: 15th January to 14th July 2017. Material & Methods: A total 100 patients came to the medical outpatients department between 25 to 45 years of age were included. Patients satisfying the inclusion criteria, subjects BMI score were checked by classifying him/her obese, overweight or normal weight. Periodontal pocket depth was observed by WHO probe of one tooth from each male and female patient. Frequency of periodontal disease was seen in subjects. Results: Age range in his study was from 25 to 45 years with mean age of 36.9 ±7.51 years. In 100 patients 66 (66%) were females & 34 (34%) were males and with male to female ratio 1.9:1. Periodontal disease was seen in 47 female patients (71%) and in 24 male patients (70%). Pocket depth was present in over weight and obese patients more than normal weight. Conclusion: current study accomplished that there is positive association of periodontal disease in overweight and obese patients. The incidence of periodontal disease was highest in female obese patients.

Objectives: Developed and developing countries are facing an obesity epidemic with various health consequences. Few studies have addressed the relationship between obesity and periodontal health. The present study assessed the association of ideal weight, overweight and obese patients in two age groups. To compare frequency of periodontal disease among ideal weight, overweight and obese patients presenting in a tertiary care hospital. Study Design: Cross-Sectional Study. Setting: Medical outdoor at tertiary care hospital in Pakistan. Period: 15th January to 14th July 2017. Materials & Methods: A total 100 patients came to the medical outpatients department between 25 to 45 years of age were included. Patients fulfilling the inclusion criteria, subjects BMI score was determined by classifying him/her obese, overweight or normal weight. Periodontal pocket depth was determined by WHO probe of at least one tooth from each sextant under supervision of my supervisor and three senior trainees. Frequency of periodontal disease was seen in ideal weight, overweight and obese subjects in both age groups. Results: Age range in his study was from 25 to 45 years with mean age of 36.9 ±7.51 years. Out of 100 patients 66 (66%) were females & 34 (34%) were males and with male to female ratio 1.9:1. Periodontal disease was present in 47 female patients (71%) and in 24 male patients (70%). Periodontal disease was present in over weight and obese patients more than normal weight. Conclusion: This study concluded that there is positive correlation of periodontal disease in overweight and obese patients. The frequency of periodontal disease was highest in old obese patients.
