Background: Meat inspection is one of the essential tools for ensuring good quality and safe meat. The objective of this study was to evaluate carcass condemnation of cattle slaughtered in Oshana region, North of Namibia. Methods: In this 4-year retrospective study, causes, patterns, and economic implications of carcass condemnation of cattle slaughtered in Oshana region, North of Namibia were evaluated based on post-mortem inspection procedure. The SPSS software version 25 was used for statistical analysis. Results: Overall, 0.37% (120 out of 32 648) beef carcasses were condemned during the period of this study. The major causes of condemnation of carcasses were bruising (60 out of 120; 50%), followed by pus contamination. The condemnation rate in female cattle (65%) was significantly (p<0.05) higher than male cattle (35%). Overall, a significantly greater number (p<0.05) of carcasses were condemned in summer (74.2%) than in winter (25.8%). Conclusion: This study identified bruising, pus contamination, and cachexia as the major causes of bovine carcass condemnation in North of Namibia and showed that carcass condemnation rate varied with the year, season, and age.

Pericoronitis is an infectious disease affecting the operculum overlying a semi-erupted or erupting tooth. Pericoronitis occurs mainly or particularly on the lower third molars. It is painfully debilitating at times and it's a common periodontal emergency found for many diseases, with tobacco being the major modifiable risk factor. It has a negative impact over oral health and oral hygiene. The aim of this study is to analyse the prevalence of pericoronitis among smokers. Patients included in this retrospective study were those with a diagnosis of pericoronitis from July 2019 till March 2020. Socio-demographic and clinical data of all the 109 patients collected such as age, gender, tooth or teeth affected by pericoronitis and treatment undergone were retrieved from the recorded details of the patients. This data was tabulated in excel and then imported to SPSS software for statistical analysis. During the study period, 109 patients presented with pericoronitis. The peak age for the prevalence of pericoronitis was 20-25 years accounting for 75.2% of the patients. The prevalence of lower left third molar (54.1%) being affected with pericoronitis was higher than the lower right third molar being affected (45.9%). Extraction (95.4%) was the frequently performed treatment for pericoronitis. Pericoronitis occurs more often in 20-25 years of age patients who are smokers. While the lower left third molar being the most common tooth involved in pericoronitis and extraction of the affected teeth was the treatment of choice among the majority of the population.

Knowledge And Attitude

The most unexpected pandemic global outbreak is COVID 19 which is a newly discovered viral infection which originated in Wuhan, China and it caused the outbreak of pneumonia in the rest of the world. Dental practitioners are more susceptible to COVID 19 infection as their work is related to the aerosol formation during various procedures through which the virus spreads. The aim of the study is to create awareness about precautionary measures against COVID- 19 exposure among dental practitioners in Tamilnadu. A Survey based questionnaire was formulated with questions related to the various precautionary measures to be adopted by dental practitioners which would be effective to prevent Covid-19 exposure. A questionnaire with a total of 20 questions was circulated among dental practitioners and the responses were collected by google forms SPSS software statistical analysis was done. The overall awareness of dental practitioners against Covid-19 was above average. The dental practitioners were relatively well aware of the precautions to be adopted while treating the patients, but the implementation in practice is lacking due absence of hands-on experience in using various kinds of PPE. There is a gap between knowledge and attitude and practice among the participants of this survey. It is therefore essential to plan for organising training sessions and hands-on workshops for the use of PPE and public training of the general population regarding Covid-19 to improve the knowledge among the patients visiting the dental clinic as well.

Introduction: The aim of this retrospective study was to analyze the radiographic peri-implant bone loss of bone level implants and tissue level implants with a convergent neck in screw-retained single crowns and in screw-retained fixed partial prostheses, after two years of functional loading. Materials and methods: The sample was divided into two groups according to their type: Group I: supracrestal implants with convergent transmucosal neck; Group II: crestal implants. In each group we distinguish two subgroups according to the type of prosthetic restoration: single crowns and a three-piece fixed partial prosthesis on two implants. To quantify bone loss, parallelized periapical radiographs were analyzed at the time of implant placement and after two years of functional load. Results: A total of 120 implants were placed in 53 patients. After statistical analysis it was observed that for each type of implant bone loss was 0.97 ± 0.91 mm for bone level and 0.31 ± 0.48 mm for tissue level. No significant differences were found regarding the type of prosthesis and the location (maxilla or mandible) of the implants. Conclusions: Tissue level implants with a convergent transepithelial neck exhibit less peri-implant bone loss than bone level implants regardless of the type of prosthesis.

We compared the prevalence of ultrasound signs of adenomyosis in women with endometriosis who underwent surgery to those who were managed conservatively. This was a retrospective study of women evaluated at a tertiary endometriosis referral center who underwent 2D/3D transvaginal ultrasound. Adenomyosis diagnosis was based on the presence of at least three sonographic signs. The study group subsequently underwent laparoscopic surgery while the control group continued conservative management. Statistical analysis compared the two groups for demographics, symptoms, clinical data, and sonographic findings. The study and control groups included 244 and 158 women, respectively. The presence of any, 3+, or 5+ sonographic signs of adenomyosis was significantly more prevalent in the study group (OR = 1.93–2.7, p < 0.004, 95% CI; 1.24–4.09). After controlling for age, for all findings but linear striations, the OR for having a specific feature was higher in the study group. Women in the study group with ≥ 5 sonographic signs of adenomyosis had more than twice the risk of experiencing infertility (OR = 2.31, p = 0.012, 95% CI; 1.20–4.45). Sonographic signs of adenomyosis are more prevalent in women with symptomatic endometriosis who underwent surgery compared with those who continued conservative management. Women with 5+ findings have a significantly increased risk of infertility. Adenomyosis on ultrasound should be considered in the management decisions regarding these patients.

The o-rings in ball retained overdentures deteriorate with time and need replacement to restore the retentive quality. We evaluated retrospectively the mechanical properties of o-rings after 3 years in function in one and two-piece implant-supported overdentures. The o-rings were retrieved from one-piece (Myriad snap, Equinox-Straumann, 3.3 x 13mm) and two-piece (Neo Biotech, 3.3 x 13mm) implant-supported overdenture patients. A total of 16 pairs of matrices were tested for wear, type of damage and elasticity using Pin on Disc method, USB Digital Camera in 30x zoom and Universal Tensile Machine respectively. The statistical analysis for independent groups were done with the Mann-Whitney U test. Assessment of used O-rings showed 84% more wear in the two-piece system with an abrasive type of damage while 46% wear in the one-piece system with a compressive type of damage. The o-rings in one-piece system showed increase in elongation and maximum displacement to 2% and 7% respectively, while two-piece system showed decrease in elongation and maximum displacement by 13% and 6% respectively. In one-piece system, the loss of retention was more with slow wear rate and in two-piece system, the wear resistance of O-rings decreased due to increased stiffness. Further studies to evaluate the changes in O-ring with increased sample size and at interval 1 year will pave way for insight into the progressive changes in the mechanical properties of an O-ring.

Purchasing specifications for beef carcasses have been aimed at reducing carcass variability and elevating the visual and keeping qualities of retail cuts. But more recently, the Meat and Livestock Commission's blueprint for improved consistent quality beef has incorporated a number of post-mortem treatments aimed at improving tenderness. Do these treatments which include electrical stimulation, pelvic bone suspension, slow chilling and prolonged ageing, exert an influence on quality which masks the intrinsic variation due to the primary production factors of feed, age, sex and possibly breed, or are the production and post-mortem effects additive? To what extent are the post-mortem treatments themselves additive?

Objective: To determine the prevalence and distribution of premature eruption and agenesis of premolars in a sample of Turkish children. Study design: A sample of 1715 patients aged 5 to 11 years was selected. Panoramic radiographs were used to assess premature eruption and agenesis of premolars. Developmental stage of erupted premolars was assessed using Demirjian’s method and selecting prematurely erupted premolars on the basis of clinical eruption with a root length less than half of their final expected root lengths. Statistical analysis was performed using chi-square test (p &lt;.05). Results: One hundred fifteen (6.7%) of 1715 patients presented at least one premolar agenesis with no significant sex difference (56 boys, 59 girls). Mandibular second premolars were the most absent teeth. Multiple agenesis of premolars (3.4%) was more common than single agenesis (3.3%). A total of 85 (5.0%) patients (51 boys, 34 girls; no significant sex difference) had at least one prematurely erupted premolar, and maxillary first premolars were most commonly affected. Early erupted premolars were in stage D or E based on Demirjian’s dental formation scale. Conclusions: The prevalence of premature eruption and agenesis of premolars in Turkish children were 5.0% and 6.7%, respectively. Both conditions are not uncommon and may highlight the need for early diagnosis to prevent subsequent clinical problems.
