ABSTRACT
PURPOSE: The aim of the retrospective study is to conduct an epidemiological evaluation of farm-based/farm-related maxillofacial injuries to assess the pattern and severity of maxillofacial injuries sustained and to formulate prevention strategies. MATERIALS & METHOD: In this analytical retrospective study, records/case sheets of patients presenting with trauma sustained in farm-based settings in a government hospital catering to rural and semi-urban population from January 2014 to Dec 2017 were analyzed to assess the incidence, pattern, etiology and trauma configurations of maxillofacial injuries sustained. RESULTS: Out of a total of 11,736 trauma cases, 2484 patients suffered injuries in farm-based settings. Out of these, 334 patients had maxillofacial injuries. Mandibular condylar fracture along with parasymphysis fracture was the most common fracture configuration. Injuries while working with non-motorized machinery followed by working around farm livestock were the most common etiological factors in farm-related trauma. CONCLUSION: Maxillofacial injuries account for a significant percentage of injuries suffered in a farm-related environment. Through this study, we have identified the patterns of maxillofacial injuries occurring in such an environment, and the data thus obtained can be used to develop various ergonomic and safety interventions in terms of machinery design and handling along with implementation of training programs and enforcing strict safety guidelines to minimize maxillofacial trauma in farm-based settings.
ABSTRACT
INTRODUCTION: Odontogenic infections are mixed aerobic-anaerobic microbial flora. Infections caused by anaerobic bacteria are serious and life-threatening. The microbial specificity in odontogenic infections is technique sensitive depending on the sampling and culturing of specimens. MATERIALS AND METHODS: A prospective study was carried out on 100 consecutive cases of odontogenic infections treated at our institute over a period of 5 years by surgical intervention and intravenous antibiotics. This study evaluates the pathogenic potential and virulence factors of aerobes and anaerobes as well as its synergistic interrelations with other infectious flora, by culturing of specimens and testing antibiotic sensitivity in standard microbiological methodology in correlation with patient demographic factors. RESULTS: Of the 100 patients of odontogenic space infection, males were more affected, between third and fourth decades. Caries is the most common etiology with involvement of mandibular molars. Submandibular and buccal space is commonly involved. The most common microorganisms isolated being Staphylococcus aureus and Streptococcus viridans are facultative anaerobes which belong to aerobes and Peptostreptococcus predominated among obligate anaerobes. The empirical antibiotic regimen followed is amoxicillin plus clavulanic acid with Metronidazole, followed by surgical treatment. Clindamycin was preferred as the second line of choice in patients resistance to penicillin drugs with comparable efficacy in it. CONCLUSION: Our study expanded the knowledge base of the microbial flora associated with odontogenic infections, with special reference to anaerobes. Successful management of odontogenic space infection lies in decompression, removal of etiological factors, and also in selecting appropriate antimicrobial therapy depending on microbial flora isolated, for recovery of patients and preventing complications associated with fascial space infection.
ABSTRACT
AIM: To compare the efficacy of intravenous (IV), intramassetric (IM) submucosal (SM) routes & oral routes of dexamethasone administration post impacted third molar removal surgery. TYPE OF STUDY: Prospective randomized comparative clinical study. MATERIALS AND METHOD: This prospective comparative study included 60 patients with Class II and position B type of impaction (according to Pell and Gregory's classification). Patients were randomly divided into 4 groups. Group A, B, C & D patients received 8mg dexamethasone immediately post-surgical tooth removal via the IV, SM and IM route & oral respectively. Assessment of swelling, mouth opening and pain was done at intervals of 1st, 3rd and 7th post-op days. RESULTS: The average age of the patients was 27 years. The mean time taken was 20 mins 40 seconds. The IV group showed minimal swelling and better pain control on the 3rd post op day (statistically significant). All 4 routes showed comparable mouth opening results. CONCLUSION: IV administration of dexamethasone post third molar surgery has been the traditional way because of its faster onset of action and increased efficacy; IM and SM routes are also comparably effective although oral route had the best patient acceptance.
ABSTRACT
PURPOSE: To evaluate the efficacy of autologous platelet-rich plasma in soft tissue healing & bone regeneration in mandibular third molar extraction socket. METHODS: The study was conducted in 10 patients visiting the outpatient Department of Oral & Maxillofacial Surgery, requiring extraction of bilateral mandibular third molars. Following extraction, autologous Platelet Rich Plasma (PRP) was placed in one extraction socket, the other socket was studied as the control site with no PRP. The patients were assessed for postoperative pain, soft tissue healing, bone blending and trabecular formation. Radiological assessment of the extraction site was done for a period of 4 months to evaluate the change in bone density. RESULTS: Pain was less in the study site compared to control site, soft tissue healing was better in study site. Evaluation for bone blending and trabecular bone formation started earlier in PRP site compared to control, non PRP site. The evaluation of bone density by radiological assessment showed the grey level values calculated after 4 months at the PRP site were comparatively higher than the average baseline value of bone density at extraction site in control site. CONCLUSION: The study showed that autologous PRP is biocompatible and has significantly improved soft tissue healing, bone regeneration and increase in bone density in extraction sockets. However a more elaborate study with a larger number of clinical cases is essential to be more conclusive regarding its efficacy.
