Journal of Indian Academy of Oral Medicine and Radiology 2019 31(1):4-10

Aim: To assess the level of knowledge, attitudes, and practices regarding sterilization/infection control measures among undergraduate dental students. Materials and Methods: A total of 300 dental students from Manav Rachna Dental College, Faridabad, Haryana participated in this study. A questionnaire survey comprising 24 questions regarding knowledge, attitudes, and practices was completed by the participants. Results: It was observed that a majority of the students were highly concerned regarding the sterilization and infection control protocol. 96.9% students dispose of their gloves after use. About 89% are aware of the exact specifications of sterilization via autoclave. Use of mouth masks and head caps as effective infection control measures was practiced among 82.4% students. A large fraction of students comprising about 85% believed that proper sterilization could not be achieved by simple boiling of instruments. Conclusion: The level of knowledge and attitude of sterilization measures were acceptable, although compliance and practice of the same needs to be more worked upon.

Background: Oral submucous fibrosis (OSMF) is a potentially malignant disorder affecting any part of the oral cavity, sometimes pharynx associated with trismus and burning sensation. Physical therapies such as ultrasound therapy was found to have therapeutic benefits of decreasing inflammation and accelerating healing process in OSMF patients. Hence, this study was designed to evaluate the therapeutic benefit of ultrasound treatment when compared to empirical combination of intralesional dexamethasone and hyaluronidase treatment alone in OSMF patients. Objectives: To evaluate and compare the clinical efficacy of intralesional infiltration of 2 ml dexamethasone (4 mg/ml) + hyaluronidase 1500 IU, ultrasound therapy in combination with intralesional infiltration and only ultrasound therapy, in reducing the signs and symptoms in patients with OSMF. Materials and Methods: The present study was performed in the Department of Oral Medicine and Radiology, with a total sample of 33 participants grouped into Group A (intralesional infiltration of 2 ml dexamethasone 4 mg/ml + hyaluronidase 1500 IU dissolved in 0.5 ml of 2% lignocaine twice a week for 8 weeks), Group B (a combination treatment of intralesional infiltration twice a week for 8 weeks and ultrasound therapy for 15 days), and Group C (only ultrasound therapy for 15 days). The collected data were subjected to statistical analysis using SPSS 16 software. Results: Statistical analysis revealed that there was a significant difference in M.M.O in Group A (1.3 ± 0.48), Group B (2.55 ± 0.75), and Group C (1.65 ± 1.20) and also VAS score of 42% ± 0.10, 41% ± 0.13, and 15% ± 0.05, respectively, after treatment. Conclusion: The results revealed that therapeutic ultrasound can be used as an adjuvant treatment, as it can alleviate the signs and symptoms of patients suffering from OSMF, thus improving the quality of life.

Journal of Indian Academy of Oral Medicine and Radiology 2019 31(1):17-23

Objective: Mental foramen is a vital anatomical structure in human mandible as they are important for dental surgeons for extraction, implant placement, osteotomy procedures, anesthetists in nerve block, and surgical procedures to avoid injury to neurovascular bundle in mental foramen area. The aim of this study was to compare the position, shape, size, and distinctness of mental foramen using orthopantomogram (OPG) and digitalized volumetric tomography (DVT). Materials and Method: This study was conducted on 25 individuals for both the genders. Position, shape, size, and distinctness of mental foramen were compared using OPG and DVT and were evaluated by Expert three-dimensional (3D) software in DVT and Annotation software in OPG. Results: Mental foramen was found to be on the vicinity of the second premolar region with respect to apices of premolars and molars and was more common in the middle third region of the jaw bone with respect to superoinferior cortex of the mandible in vertical plane. There was no significant difference in the position of the mental foramen using OPG and DVT. The commonest shape of mental foramen was found to be oval and was better defined in DVT. The size of the mental foramen was observed to be 0.49 ± 0.05 and 0.51 ± 0.06 cm in OPG and DVT, respectively, and more distinctly visible in DVT. There was no significant difference in the position, shape, size, and distinctness of the mental foramen among genders. Conclusion: Conventional radiography can be initially done for the position of the mental foramen but the details must be confirmed using 3D volumetric radiography to avoid any kind of procedural complications.

Background: Oral Submucous fibrosis (OSMF) is a premalignant condition affecting the oral mucosa. It is observed to have a multifactorial etiology including genetic predisposition and autoimmune origin. This study aimed to study the etiological role of immunological factors in OSMF. Settings and Design: It was a prospective study carried out in the Department of Oral Medicine and Radiology at Lenora Institute of Dental Sciences, Rajahmundry. Aims and Objective: To estimate and compare the serum IgG and IgA between the OSMF subjects and controls. To assess the statistical significance of the difference in the levels of albumin, globulin, total protein, IgG and IgA between study group and control group if any. Materials and Methods: It was an observational study in which the serum albumin, serum globulin, total protein, IgG and IgA were evaluated in a total of 60 patients who gave consent to participate in the study. Results and Discussion: Increase of IgG was observed in 9 (30%) subjects of the OSMF group and in 4 (13.2%) of the control group. IgA level was increased in 2 (6.6%) subjects of OSMF group and in 5 (16.6%) subjects of the control group. However, this difference was not statistically significant. Conclusion: The findings from the study indicated an alteration in the immunoglobulin level in patients with OSMF. However, the association was not significant. Therefore, further and larger studies are advocated to verify the immunological association with OSMF. One important observation made in the study was a positive association between the duration of exposure and stage of OSMF. This implies that interventions which modify the arecanut chewing habits can bring about a reduction in OSMF and in turn oral cancer.

Journal of Indian Academy of Oral Medicine and Radiology 2019 31(1):29-35

Background: Orofacial pain disorders and their management forms an important and integral part of our oral medicine specialty. Only oral physicians are well-trained to provide non-surgical treatment of these complex disorders. Today, the escalating costs of drugs and several adverse effects associated with modern medicines have led to the search of alternative systems all over the world. Hence, this study is an effort to assess the efficacy of holistic approaches (naturopathy and yoga) alone as well as in combination with pharmacological therapy in the treatment of chronic orofacial pain of non-odontogenic origin. Materials and Methods: The present study was conducted on 60 patients who were randomized into three groups A, B and C, each group consisting of 20 patients (10 of myofascial pain and 10 of trigeminal neuralgia). In group A it was prescribed conventional medicines for their respective treatment. Holistic approaches (naturopathy and yoga) were added with conventional pharmacological therapy in group B and only holistic approaches were performed in group C. The duration of treatment was of 3 months a and the patients were analysed using pain scale, quality of life scale (QOL) and stress scale after every ten days follow-up. Results: The patients of trigeminal neuralgia showed best result when treated with pharmacological treatment. The holistic approaches showed significant results only when combined with pharmacological therapy for the treatment of trigeminal neuralgia. On the other hand, holistic approaches works best in myofascial pain both alone and in combination with pharmacological therapy. Acupuncture and facial massage along with yoga have a great impact on quality of life by reducing stress and anxiety of the patient. Conclusion: Holistic approaches are useful means in treating patients with chronic orofacial pain as it eliminates the risk of adverse effects associated with long term use of muscle relaxants and anti-convulsants.

Journal of Indian Academy of Oral Medicine and Radiology 2019 31(1):36-39

Introduction: Xerostomia and salivary gland hypofunction are associated with advancing age, autoimmune diseases such as Sjφgren's syndrome, head and neck radiation, smoking and recreational drug usage. Palliative management of xerostomia included topical agents such as ice chips, saliva substitutes, increasing water intake, paraffin and systemic agents like pilocarpine had been used. The above mentioned agents had side-effects and have led to find newer modalities like electrical and chemical stimulation. Aim: The present study was undertaken to evaluate the effectiveness of citric acid and transcutaneous electric nerve stimulation (TENS) as a means of stimulating salivary function in healthy adult subjects. Materials and Methods: Hundred adult subjects, 50 males and 50 females between the age group of 18-45 years, with no history of salivary gland disorder were randomly enrolled in the study. During the first visit unstimulated whole saliva was collected in a graduated tube and aafter 1 hr stimulated saliva was collected using citric acid and obtained saliva was measured and recorded. At the second visit, unstimulated whole saliva was collected in a graduated tube and after 1 hr stimulated saliva was collected with TENS and obtained saliva was measured and recorded. Results: The obtained data of unstimulated and stimulated saliva of the subjects was tabulated and subjected to statistical analysis using paired and unpaired t-test. The results showed increased salivary flow rate with both the modalities. And comparative evaluation revealed greater salivary flow rate with citric acid when compared to TENS. Conclusion: The present study substantiated the fact that citric acid as well as TENS can be used as an effective and wholesome method in stimulation of whole salivary flow rate in patients with xerostomia and salivary gland hypofunction.

Journal of Indian Academy of Oral Medicine and Radiology 2019 31(1):40-44

Introduction: Stafne's cyst (SC) is a bone depression found on the lingual side of the mandible. It is a sharply demarcated osteolytic lesion of the mandible, caudal to the inferior alveolar nerve and restricted to the regions of the molars and mandibular angle. Purpose: Stafne's bone cyst is usually asymptomatic being diagnosed on the routine radiographs as an incidental finding hence, its actual prevalence is unknown. Moreover, the lesion simulates many odonogenic pathologies thereby, and the entity remains a diagnostic challenge. So, the present study was conducted to investigate the prevalence of SC in Jodhpur population of Western India. Materials and Methods: A retrospective analysis of 18040 OPGs was done on the basis of diagnostic criteria described by Stafne. Results: A total of 6 cases fulfilled diagnostic criteria of SC (0.03%), 4 cases were reported in men (66.6%), at a mean age of 50.75 years, and 2 cases in women (33.3%), at a mean age of 31.5 years. Involvement of SC on left and right side of the mandible was given as 4:2 in ratio. All 6 cases of SC was found in the body of mandible (100%). Rare case of double unilateral form of SC was reported in 1 patient. Conclusion: Orthopantomographs (OPGs) may ensure initial opinion regarding the diagnosis of SC and alert the clinicians to exclude other potential pathologies to avoid invasive procedures.

Introduction: Aloe vera has various pharmacological actions due to which it has been selected as an alternative treatment modality in treating various oral diseases. It has antibacterial, antifungal, antiinflammatory, antioxidant, antitumor, and immune boosting. It has been used for the management of oral lesions such as oral lichen planus, oral submucous fibrosis, radiation-induced mucositis, burning mouth syndrome, xerostomia, recurrent aphthous ulcers. Aim: The aim of this study is to the compare the effects of the topical aloe vera gel and triamcinolone acetonide 0.1% in patients with minor ulcers of aphthous stomatitis. Materials and Methods: Thirty-four patients presenting with clinical signs and symptoms of aphthous stomatitis were included for the randomized single blinded study after informed consent. Group A patients received topical aloe vera gel (Forever Bright Aloe vera Gel), and Group B patients received topical triamcinolone acetonide 0.1% (kenacort oral paste) three times a day for 7 days or till the ulcer heals completely. The parameters such as the size of the ulcer, burning sensation, and pain were recorded at each visit. Results: In this study, kenacort oral paste was found to be effective than aloe vera in wound healing (measured by the diameter of ulcer). In contrast, aloe vera gel had a better response in terms of pain and burning sensation. Conclusion: Aloe vera has a wide spectrum of unique properties and uses. It is a promising agent in treating oral lesion in the field of oral medicine. It can be used as an alternative medicine and in patients who are allergic to steroid medication.
