Comparative evaluation of efficacy of physics forceps versus conventional forceps in therapeutic extractions of premolars: a prospective clinical study

Background: Dental extraction is the removal of a tooth from the oral cavity and is the most common procedure performed in oral surgery. Conventional exodontia tends to cause unnecessary trauma leading to postoperative pain, loss of tissue and stress for the patient. ‘Atraumatic’ dental extraction techniques have nowadays gained popularity and in such case, physics forceps can be helpful in achieving such results. The aim of the study was to evaluate and compare efficacy of physics forceps versus conventional forceps in therapeutic extraction of premolars.Methods: A total of 35 patients requiring extraction of premolars in maxillary or mandibular arch or both arches for orthodontic treatment purpose were included and divided into groups A and B wherein right sided extractions performed with physics forceps were compared with left sided extractions carried out using conventional forceps in terms of time taken for extraction, bone and soft tissue injury, success score and pain assessment.Results: The present study suggested statistically significant difference between both the groups. Time taken for extraction, trauma to gingival tissue, bone loss, and visual analogue scale (VAS) score was significantly lesser with physics forceps group, when compared to conventional forceps group. Moreover no significant difference in success score was noted between both the groups.Conclusions: Physics forceps are comparatively superior to conventional extraction forceps in terms of lesser time taken for the procedure, lesser tendency to induce trauma to both hard and soft tissue and have been found to induce comparatively lesser pain post extraction

Prevalence of mental nerve injury in facial fractures: a 3 year retrospective study

Background: Mandibular fracture is the most common facial bone fracture. Fractures occurring at the Para symphysis region frequently results in mental nerve injury, due to which anaesthesia or paraesthesia of the skin and mucous membrane within the distribution of mental nerve may be observed and may cause reduced quality of life for patients. Aim of this study was to retrospectively analyse and evaluate the prevalence rate of mental nerve injury in patients that reported to the department of oral and maxillofacial surgery, managed conservatively or open reduction and internal fixation method during the last 3 yearsMethods: Patients with neurosensory deficit following para symphysis fracture were recorded, statistically analyzed and results and observation were prepared from it.Results: The patients with age group 21-30 diagnosed with para symphysis fracture constituted 25% of all operated case and were found to be more associated with midface and angle fracture. Etiology behind the trauma was mostly as a result of RTA. Neurosensory disturbances as a result of mental nerve injury were found to be associated in 20.89% case, out of which in most of the cases, it gradually recovered within a duration of 7-15 days.Conclusions: RTA’s have been a prime cause for para symphysis fracture, which may at times accompany neurosensory deficit following trauma or may occur post-surgery, has been found to cause troublesome sequelae and reduced quality of life. Moreover, further research study needs to be carried out over a larger time span having a larger group of patients

Evaluation of efficacy of submucosal tramadol after mandibular third molar surgery: a prospective pilot study

Background: Surgical extraction of mandibular third molar is one of the most commonly performed procedure in oral and maxillofacial surgery. Its removal causes swelling, trismus, and moderate to severe pain which can be treated with various NSAID’s drugs, which have numerous side effects and gastric disturbances. In order to bypass such disturbances, Tramadol may be considered as an alternative for such patients. The aim of the study was to evaluate analgesic efficacy of submucosal tramadol and its implication over swelling and mouth opening after mandibular third molar surgery.Methods: This is a prospective study where in after post-surgical extraction of mandibular third molar, efficacy of submucosal injection of tramadol is evaluated in terms of pain and its implication over swelling and mouth opening.Results: The present study suggested there was statistically significant VAS score for pain after submucosally injecting tramadol post-surgical extraction of mandibular third molar in the following visits- 4hourly, 8hourly and 24hourly. In respect to swelling, statistically significant values was noted during 24hr and 72 h our post extraction. Also in case of mouth opening, statistically significant values were found 24 hourly.Conclusions: The present pilot study concluded that submucosal tramadol post mandibular third molar extraction has been effective in reducing pain, limiting post-extraction swelling and less impacting mouth opening by inducing less complications thereby bypassing gastric disturbances

Design Engineering in the Age of Industry 4.0

Industry 4.0 is based on the digitization of manufacturing industries and has raised the prospect for substantial improvements in productivity, quality, and customer satisfaction. This digital transformation not only affects the way products are manufactured but also creates new opportunities for the design of products, processes, services, and systems. Unlike traditional design practices based on system-centric concepts, design for these new opportunities requires a holistic view of the human (stakeholder), artefact (product), and process (realization) dimensions of the design problem. In this paper we envision a “human-cyber-physical view of the systems realization ecosystem,” termed “Design Engineering 4.0 (DE4.0),” to reconceptualize how cyber and physical technologies can be seamlessly integrated to identify and fulfil customer needs and garner the benefits of Industry 4.0. In this paper, we review the evolution of Engineering Design in response to advances in several strategic areas including smart and connected products, end-to-end digital integration, customization and personalization, data-driven design, digital twins and intelligent design automation, extended supply chains and agile collaboration networks, open innovation, co-creation and crowdsourcing, product servitization and anything-as-a-service, and platformization for the sharing economy. We postulate that DE 4.0 will account for drivers such as Internet of Things, Internet of People, Internet of Services, and Internet of Commerce to deliver on the promise of Industry 4.0 effectively and efficiently. Further, we identify key issues to be addressed in DE 4.0 and engage the design research community on the challenges that the future holds
