AIM: The purpose of this study was to determine the anesthetic efficacy of inferior alveolar nerve block (IANB) using 4% articaine and 2% lidocaine supplemented with buccal infiltration.MATERIALS AND METHODS: Forty five patients, diagnosed with irreversible pulpitis of a mandibular posterior tooth were included in the study. The first group of 15 patients received 2% lidocaine with 1:200000 epinephrine, the second group 2% lidocaine with 1: 80,000 epinephrine and the third group of 15 subjects received 4% articaine with 1:100000 epinephrine. During the access cavity preparation those patients who complained of pain received an additional buccal infiltration. The percentage of subjects who got profound anesthesia and failure to achieve anesthesia were calculated and tabulated using a visual analog scale.RESULTS: The results revealed that 87% of subjects who received 4% Articaine with 1:100,000 epinephrine got satisfactory anesthesia with inferior alveolar nerve block alone. Only 2 (13%) subjects received an additional buccal infiltration and none of the patients failed to obtain complete anesthesia with articaine. In comparison only 40% of subjects got complete anesthesia with 2% lidocaine with 1:200000 and 60% with 2% lidocaine with 1:80,000.CONCLUSION: It can be concluded that 4% articaine can be used effectively for obtaining profound anesthesia for endodontic procedures in patients with irreversible pulpitis.

Introduction: Temporomandibular disorders (TMD) are the most common non-dental cause of orofacial pain with a multifactorial aetiology. Aim: To evaluate the head and craniocervical posture between individuals with and without TMD and its sub types by photographic and radiographic method. Materials and Methods: Thirty four TMD patients diagnosed according to Research Diagnostic Criteria for TMD’s (RDC/TMD) and were divided into 2 groups: Group I (muscle disorder), Group II (disc displacement). Control group comprised of 34 age and sex matched subjects without TMD. Lateral view photographs were taken and the head posture angle was measured. Craniocervical posture was assessed on lateral skull radiograph with two angles (Craniocervical Angle, Cervical Curvature Angle) and two distances (Suboccipital Space, Atlas-Axis Distance). To compare the results, t-test was used with significance level of 0.05. Results: Head posture showed no statistical significant difference (p > 0.05) between Group I, II and control group in both photographic and radiographic methods. The cervical curvature angle showed significant difference (p = 0.045) in Group I only. Atlas-Axis Distance was statistically significant in Group II (p = 0.001). Conclusion: The present study confirmed that there is a negative association of head posture and TMD whereas, cervical lordosis was present in Group I only. © Journal of Clinical and Diagnostic Research.

Idiopathic leukoplakia is a rare potentially malignant lesion, usually found on the tongue with an increased risk of malignant transformation as compared to the tobacco associated form. The risk of malignant transformation increases with age. Diagnosis poses a challenge to the clinician as it is diagnosed by exclusion of other possible causes leading to hyperkeratosis. We present one such rare case in an elderly male patient who was followed up for a year to record the course of the lesion and to report recurrences, if any. © 2015 Journal of Clinical and Diagnostic Research.

Introduction: Tobacco use is a global health care problem. Repetitive exposure to nicotine produces neuroadaptation resulting in nicotine dependence. Smoking is associated with a range of diseases, causing high levels of morbidity and mortality and is one of the leading causes of preventable deaths, with more than 4.6 million smokers worldwide dying each year from smoking related illnesses. Stopping smoking has major health benefits. Quitting at any age provides both short and long term benefits. Materials and methods: 45 patients attending the outpatient department at the Oxford Dental College, Bangalore, were randomly allocated to three groups of interventions namely placebo, counseling and nicotine replacement therapy (NRT). Initially each one was assessed for carbon monoxide levels using a breath analyser (pico smokerlyser bedfont UK). They were followed up for six months and the carbon monoxide levels were again assessed using the same instrument. The paired t test was used to compare the results before and after the intervention. Results: The scores before the initiation of intervention and after treatment were compared and all three interventions were found to be statistically significant after six months. It was noticed that patients with very low or low dependence followed by high dependence had good response in the placebo group (68% and 47.6% respectively), in the counseling group maximum response was seen in the medium followed by the very low group (61% and 59% respectively), and maximum response was seen in very high followed by the very low group with NRT (78.7% and 60.5% respectively). Conclusion: The inference that can be drawn from the present study is that non-invasive, non pharmacological methods like placebo and counseling are effective in low to medium groups, and NRT is effective with higher nicotine dependence.

Background: Tobacco use in various forms, including with Areca nut, causes several potentially malignant disorders. Many lesions may transform into oral squamous cell carcinoma. Although patients may be aware of the hazards of tobacco habits, the lesions by themselves are insidious in nature resulting in failure of patients to present to general dentists/specialists at early stages. Our aim was to study the types of habits prevalent in the region of Rourkela in Orissa and to assess the insidious nature of the lesions associated with these habits. Not many studies have been done from this part of India. Materials and Methods: A camp was conducted for habitual users of tobacco and its products, Areca nut and other mixed habit users. A thorough history was taken of the type, duration and frequency of habits, symptoms of patients along with clinical examination by a single examiner. The data was entered in detail into an excel sheet and analysed. Results: 54.7% had lesions and 60.9 % of them were asymptomatic and rest had mild burning sensation while eating. There was a very low awareness of the presence of lesions among the patients. Conclusions: There is a need to spread the awareness of the ill effects of the tobacco and other associated habits far and wide and more importantly educate the general public on the appearance of associated lesions as these are almost always insidious in nature. The patients can self-examine, detect lesions early when present and approach the dentist at the earliest opportunity. Source
