Effect of preoperative ibuprofen on pain after lower third molar removal: A randomized controlled trial.

Aim: The aim of the study is to predict the effect of preemptive analgesics in the third molar surgery and to analyze whether the number and frequency of postoperative analgesics are reduced following the administration of preemptive analgesics. Materials and Methods: The present study was carried out on 50 patients who reported to the Department of Oral and Maxillofacial Surgery for removal of their impacted mandibular third molar. The patients were randomly divided into two groups of 25 patients each - Group A (test group) patients receiving ibuprofen (400 mg) half an hour before the surgery and placebo half an hour after surgery and the Group B (control group) patients receiving placebo half an hour before the surgery and ibuprofen (400 mg) half an hour after surgery. Both groups of patients will be instructed to avoid any drug but those prescribed (ibuprofen 400 mg SOS and rescue medication of tramadol 50 mg SOS) and not to seek any medical help elsewhere for postoperative problems. The pain was recorded using a visual analog scale. Results: Demographic data in the study show females (8%) and male (92%) patients. The average time taken for surgery was more in the control group (58.36 min) as compared to the test group (55.64 min) with no statistically significant difference. Values of pain score, medication score, number of rescue medication, and frequency at different time intervals (at baseline, after 3 h, 6 h, 24 h, and 7 days) are expressed in terms of mean and standard deviation, respectively, and the result shows the statistically significant difference for pain score at baseline and 7th-day time interval only. The distribution of different types of impaction and different types of elevation/odontotomy shows a significant association in test and control groups. Conclusion: Preoperative ibuprofen decreases the frequency and intensity of the pain. We believe that since this preoperative ibuprofen seems to be beneficial without any adverse effects, it may be used routinely in the 3rd molar surgeries and even in routine extraction.

Efficacy of bioresorbable plating system in the treatment of pediatric maxillary fractures: A short clinical study.

Aim: The aim of this study was to evaluate the efficacy, stability, and clinical outcomes of a bioresorbable plating system in the treatment of pediatric maxillary fractures. Materials and Methods: Twenty pediatric patients with maxillary fractures (13 males and 7 females) were included in this study. The 1.5- and 2.0-mm resorbable plates were used and secured with monocortical resorbable screws 6 mm and 7 mm in length. All patients were followed up for 6 months. Clinical parameters, such as pain, swelling, soft-tissue infection, malocclusion, nerve injury, and bite force for stability, were prospectively assessed. Results: Fall from height (50%) was the most common cause of etiology, followed by road traffic accidents (35%). Maxillary alveolar # (40) was the most common fracture site, followed by nasal complex # (25%) and zygomatic complex # (25%). Appropriate fixation and adequate primary bone healing was achieved in 100% of the cases. Few minor complications were observed: (1) soft-tissue infection (5%) and (2) paresthesia (10%). There was a significant increase in bite force in the incisor and molar regions. Observation in clinical parameters shows that there was a significant reduction in postoperative pain and swelling at different follow-up periods. Conclusion: Bioresorbable plating system is used as a load-sharing plate in a semirigid fixation technique after anatomic fracture reduction. Although its high costs limit its feasibility for use low infection rates, minimized second surgery for implant removal attracts its use. 1.5- and 2-mm resorbable plating system along is a good treatment modality for moderately displaced maxillary fractures in pediatric patients. Larger sample size and longer follow-up studies are required for conclusive results.

Effectiveness of cognitive behavioral therapy and basic health education for tobacco cessation among adult tobacco users attending a private tobacco cessation center.

BACKGROUND: India being major consumer of tobacco faces various problems involved for its cessation. Over the time enormous methods have been evolved which may aid in tobacco cessation. MATERIALS AND METHODS: The present study was conducted among 100 adult tobacco users attending tobacco cessation clinic. The individuals where randomized into 2 counselling groups: Group A - Basic health education (BHE) and Group B Cognitive Behavioral Therapy (CBT). Baseline evaluation of demographic parameters, smoking/smokeless behavior was recorded and Fagerstrom's test for Nicotine Dependence (FTND) was utilized to assess subjects' nicotine addiction levels. Follow up was done at intervals of 2 weeks and 4 weeks to assess the reduction in the mean FTND score. Appropriate statistical test was utilized to evaluate the results. RESULTS: The majority of individuals in the study were male in age group of 41-60 years. The reduction in mean FTND score was found in both Group A and B on follow-up. But when both groups were compared, reductions in mean Fagerstrom scores were found to be more in CBT group than in BHE group at all time intervals. CONCLUSION: Individuals in both the group have quit the tobacco use by both the interventions followed by proper schematic follow up.

AgNOR as an effective diagnostic tool for determining the proliferative nature of different types of odontogenic cysts.

OBJECTIVE: To determine the proliferative nature of different types of odontogenic cysts using silver-stained nucleolar organizer region (AgNOR) staining. MATERIALS AND METHODS: Forty histopathological sections of each of odontogenic keratocyst, dentigerous, and radicular growth were taken into study. Two sections were produced using the paraffin block of separate cases, one was stained with hematoxylin and eosin and another segment was stained with silver nitrate method. RESULTS: AgNOR staining shows black dots and other parts of nuclei show yellow-brown dots. CONCLUSION: AgNOR, which stain for NOR-related proteins, corresponds to cell multiplication. Their amount regarding the number of AgNORs per cyst can be a good marker of the proliferative action of the cell in aggressive cystic lesion having malignant potential.

Prevalence, knowledge, attitude and nicotine dependence among ESI-insured populations of Delhi NCR region: Institutional study.

AIM: To assess the prevalence of tobacco consumption among the ESI-insured patients. The study also assessed the knowledge, practice, and attitude among industrial workers as well as nicotine dependence with different forms of tobacco products consumed. MATERIALS AND METHODS: A cross-sectional study was conducted among industrial workers from various industries (small and large scale) insured under the employee state insurance corporation scheme. The study was conducted for 3 months included 500 workers of which 470 were males and 30 were females. A predesigned, pretested, and structured interviewed administered questionnaire was used to collect the data on sociodemographic factors, reasons for tobacco consumed, and level of dependencies among industrial workers. Questionnaire also included questions related to awareness regarding health hazards and lesion present in the oral cavity as a result of tobacco consumption. Fegarstrom scale was used to access nicotine dependency level. A Hindi translated version of Fegarstrom test for Nicotine dependence in the questionnaire was used which included six standard questions for both smokeless and smoked form. RESULT: Majority of both males and females consumed tobacco in smokeless (58.8%) form. Out of which 92.85% in males and 7.15% in females followed by the smoke (28.8%) form. 93.04% in males and (7%) in females (79.86%) of the tobacco users in our study were aware that consuming tobacco causes health related problems. 38.6% of the users have moderate dependency in both smoke and smokeless form. Seventy six percent of the consumers feel that they didn't have any changes in the mouth by consuming tobacco and thus never thought of quitting tobacco. CONCLUSION: Tobacco consumption among the ESI-insured patients is high. Execution of tobacco cessation programs are required to curb this trend.

Study of antibiotic efficacy of topical vancomycin powder in treatment of infected mandibular fractures and soft tissue surgical site infections.

AIMS AND OBJECTIVE: To study the antibiotic efficacy of topical vancomycin in infected mandibular fracture treatment and its effect in preventing surgical site infections. MATERIALS AND METHODS: The study comprised of 100 subjects of infected mandibular fractures requiring open reduction and internal fixation, randomly categorized into two equal groups of 50 each, that is, vancomycin group (N = 50) treated for infected mandibular fractures with topical vancomycin powder used as adjunct and non-vancomycin group (N = 50). Clinical parameters like hospital stay, postoperative infections, postoperative fever, abnormal swelling, purulent discharge, and fistula formation at surgical site and radiographic healing was evaluated and compared between the groups. RESULTS: Mean age of vancomycin group and non-vancomycin group was 32.5 and 33.2 years, respectively. Demographic factors of the patients like age, sex, and hospital stay (3 ± 0.5 days) did not show significant difference between two groups. Vancomycin group shows 1 hyperthermia, 2 abnormal swelling and discharge, whereas non-vancomycin group shows 6 hyperthermia, 5 postoperative abnormal swelling and discharge with statistically significant (P < 0.05). Culture sensitivity of discharged fluid shows staphylococcal + MRSA infection in two patients in vancomycin group and eight patients in non-vancomycin group. Bony healing in vancomycin group shows one patient had non-union and one had graft rejection, whereas five patients had non-union and graft rejection in non- vancomycin group. The comparative results were statistically significant (P < 0.05). CONCLUSION: From the result of our study we can conclude that routine use of vancomycin powder in surgical site as a surgical adjunct reduces the incidence of infections at surgical site when it is applied in addition to standard antibiotic prophylaxis. Topical application into a surgical wound also reduces the risk associated with parenteral administration of vancomycin.

A randomized controlled trial comparing the radiographic evaluation of crestal bone resorption in single implant versus two implant-retained overdentures.

AIM: The aim of this study was to evaluate and compare radiographically the amount of crestal bone resorption during healing and loading period in single implant versus two implant-retained mandibular overdentures in totally edentulous patients. MATERIALS AND METHODS: A total of 20 edentulous patients (12 male and 8 female) with age range of 58.6 years were included in this clinical trial which was completed in four phases (clinical and radiographic diagnosis, surgical phase, implant loading phase, and bone level measurement phase). The eligible patients were randomly allocated in two equivalent groups of 10 participants each per group. The allocation was in 1:1 ratio via randomized chit method. Group I included the case group, that is, single implant, and Group II included the control group, that is, two implants located in mandible. A total of 30 implants were placed in Group I and 20 implants in Group II. Digital intraoral peri-apical radiographs (RVG 5100) were used for measuring the bone level immediately after implant surgery, 1 month, 3 months, 4 months, and 6 months. RESULT: This study showed that there was a mean crestal bone loss of 0.7 mm between the tip of the implant and alveolar crest at the end of 6 months after implant placement in single implant Group I while 0.67 mm in case of Group II two-implant-retained mandibular overdentures. The percentage of crestal bone loss after 6 months follow-up was 6.45% in Group I which was statistically insignificant compared with Group II where 6.25% of bone loss was recorded. CONCLUSION: Single implant-retained mandibular overdentures could be used as another alternative treatment option for completely edentulous elderly patients with severely resorbed ridges and financially and systemically compromised conditions.

A retrospective cross-sectional study of maxillofacial trauma in Delhi-NCR Region.

AIM AND OBJECTIVES: To evaluate the pattern, prevalence, etiology, site of fractures, and their management in patients with maxillofacial injury in Delhi-NCR region. MATERIALS AND METHODS: A total of 1278 maxillofacial trauma patients visiting different registered hospitals from Delhi-NCR region from January 2012 to December 2017, treated by open reduction and internal fixation under general anesthesia (GA)/local anesthesia (LA) or closed reduction/conservatively, were taken into the study. The parameters considered in the study were age and sex distribution, etiological factors and incidence of maxillofacial trauma, pattern and site distribution of maxillofacial fractures, and management. RESULTS: From a total of 2250 trauma patients, 1278 patients (1053 males and 225 females) had maxillofacial injury. The average prevalence rate was 56.8%. Yearly incidence rate was 20.4%. Road traffic accident (RTA) was the most common cause of trauma in 1029 (80.5%) patients, followed by physical assault [158 (12.3%)] with significant male predominance in different age groups. Isolated mandibular fractures were the most common [48.6% (parasymphysis 31.6%, condyle 28.2%)], followed by midface with maxilla fracture [27.6% (zygomatic bone and arch 50.2% and Lefort II fractures 18%)]. Treatment modalities were conservative management, closed reduction, and open reduction with internal fixation under GA/LA. CONCLUSION: RTA followed by physical assault is still the leading cause of maxillofacial trauma in young males in Delhi-NCR region. Mini plate osteosynthesis is the main treatment procedure for maxillofacial trauma. We need to enforce strict traffic rules, road safety law, and preventive measures along with improvement in education and socioeconomic status in the population to avoid maxillofacial injuries.

Comparative study of risk indicators associated with tooth loss among adult population in urban and rural areas of Muradnagar, Ghaziabad, Uttar Pradesh, India.

BACKGROUND: Oral health objectives prescribed by World Health Organization for the year 2020 have expressed that there ought to be an expansion in the quantity of people with functional dentitions (at least 21 common teeth) at ages of 35-44 and 65-74 years. AIM: The aim of this study is to examine the prevalence of tooth loss and to evaluate and compare the risk indicators associated with tooth loss among adult population in urban and rural areas of Muradnagar, Ghaziabad. MATERIALS AND METHODS: A cross-sectional study was led among 1200 adults aged 35-74 years in urban and rural areas of Muradnagar, India. Information was assembled by an interview followed by clinical examination (number of missing teeth). Demographic and socioeconomic factors and self-perceived oral health were the independent variables assessed. One-way analysis of variance, post-hoc test (Bonferroni), Chi-square test, Student's t-test, and logistic regression analysis were used for statistical analysis. RESULTS: Low educational status, no dental check-ups, low frequency of brushing, older age, and smoking habit were independent risk factors for tooth loss. The odds of tooth loss in older adults and illiterates were higher; the odds for tooth loss among those who expressed their desire for replacement of missing teeth were 1.3 times lower than their counterparts. CONCLUSION: The experiences gained up showed that tooth loss was very pervasive in Muradnagar populace and the critical hazard indicators identified were age, education, socioeconomic status, and cigarette smoking.

Association between maternal dental anxiety and its effect on the oral health status of their child: An institutional cross sectional study.

AIM: To assess the association between maternal dental anxiety and its effect on the oral health status of their child, in Murad nagar -An institutional cross-sectional study. MATERIALS AND METHODS: Among the randomly selected 200 mother-child pairs, a cross-sectional study was done. The children of 2-5 years were selected for the study. A five-level Modified Dental Anxiety Scale (MDAS), Hindi edition, was used to assess dental anxiety among the mothers. Clinical examination of the wards was finished by using a modified gingival record and WHO dentition status (2013). The SPSS software version 20 was used for statistical analysis. RESULTS: Approximately, 61% of the children were males, and 39% were females. The modified gingival index (MGI) score was high, if there should arise an occurrence of high MDAS values. The mean MGI score was most astounding in phobic class of MDAS and least in the not anxious classification. The MGI score expanded on increment in maternal anxiety. Dental caries expanded in kids, if there should be an occurrence of high maternal dental uneasiness. The MDAS demonstrated a critical association with clinical oral health results of the child. The children whose mothers were "extremely anxious" (phobic) had the highest mean decayed, missing, or filled teeth. CONCLUSION: Maternal dental anxiety significantly affects the oral health status of their ward.

Assessment of efficacy of ultrasonography in cervical lymphadenopathy in oral malignancies.

AIMS AND OBJECTIVES: To substantiate the use of ultrasonography in diagnosis of cervical lymphadenopathy in oral malignancies and to assess if ultrasonographic examination done prior to lymph node (LN) biopsy can yield important information regarding the diagnosis. MATERIALS AND METHODS: Twenty subjects with histopathologically confirmed oral malignant lesions with clinically palpable and untreated cervical LNs included into study. These patients were subjected to clinical examination (number of LNs, shape, size, location, overlying temperature, overlying skin, tenderness, consistency, and fixity to the underlying structures), and ultrasonographic evaluation (number of LNs, shape, size (mm), location, borders, matting, peripheral halo, hilum, calcification, necrosis, reticulation, and echogenicity) of the LNs, and finally, histological assessment was done after surgical excision during the course of treatment. RESULTS: Predominantly male (65%) patients were having with malignant LN involvement with age group of 60-69 years, i.e., 35%. Ultrasonogram is superior to clinical examination as it detected additional 49 nodes. Malignant nodes tend to have longest axial diameter (17 mm with standard deviation of 8.7 mm). Over all 52 malignant nodes were round, whereas 35 nodes were oval in shape. Most of the nodes were detected in submandibular region. Around 61 (70.9%) nodes had sharp borders and 26 (29.9%) had smooth borders. Loss of echogenic hilus is a common feature of malignancy showing 70% sensitivity and 67% specificity. Most of malignant nodes were hypoechoic. Around 51 (58.6%) of nodes showed intranodal necrosis, whereas it was absent in 36 (41.4%) nodes. Matting and edema were present 25 (28.7%) nodes. Intranodal calcification was present in 37 nodes. Sensitivity of USG was 90%, whereas specificity was 100%. CONCLUSION: Ultrasonographic examination of cervical LNs can yield important information regarding the diagnosis. Ultrasound examination should be done prior to FNAC and ideally an ultrasound-guided FNAC.

Effect of gutkha chewing on periodontal health and oral hygiene of peoples in Delhi NCR region of North India: A cross-sectional multicentered study.

BACKGROUND: In India, gutkha is popular among all socioeconomic groups, since it is available easily and is of less cost. Various investigations have demonstrated the relationship of gutkha biting with periodontal status and oral hygiene. AIM: The aim of this study is to assess the effect of gutkha chewing on periodontal health and oral hygiene of patients attending the dental department in India. MATERIALS AND METHODS: A cross-sectional investigation was directed among 200 patients going to dental camps. Among them, 100 were gutkha chewers and 100 were smokers. The oral hygiene status of selected patients was determined by using the Simplified Oral Hygiene Index. Various periodontal parameters like a gingival recession, clinical attachment loss, mobility, and furcation were used to evaluate the periodontal status. Data were collected and analyzed with the help of SPSS software version 20. RESULT: Among the 200 subjects, 102 were males and 78 were females. In 100 gutkha chewers, 67% were male and 33% were females. About 68% gutkha chewers showed poor oral hygiene as compared to nonchewers (41%). The values of all the periodontal parameters were significantly higher in gutkha smokers compared to nonchewers. CONCLUSION: Gutkha chewing has a strong effect on oral hygiene. The findings can contribute to the evidence of smokeless tobacco (gutkha) as a risk factor for periodontal disease.
