ABSTRACT
A double blind, randomized controlled clinical trial was done to investigate the effect of analgesics aceclofenac and ibuprofen in reducing pre-operative pain following local anesthesia with lidocaine and articaine. One hundred and twenty patients with irreversible pulpitis of the maxillary premolars and first molar region were randomly divided into 2 groups with group 1, 2% lidocaine with 1:200000 epinephrine and group 2, 4% articaine with 1:100000 epinephrine. The two groups were again subdivided into 3 subgroups in which patients were given identical capsules containing ibuprofen 600 mg, aceclofenac 100 mg, placebo (vitamin tablets), half an hour before the administration of buccal infiltration anesthesia. Patients indicated their pain scores on a Heft Parker Visual analog scale (VAS). Infiltration anaesthesia was given under sterile condition.1 min after the injection, electric Imrana Tasneem, B.R.

Effect of premedication with aceclofenac and ibuprofen on the success rate of two different local anesthetic agents in irreversible pulpitis cases of maxillary posterior teeth (a prospective randomized double-blind clinical trial). IAIM, 2019; 6(5): 40-45. Page 41 pulp test and cold test were done and testing was repeated after every 2 minutes for a total of 10 minutes. Premedication with ibuprofen (600 mg) and aceclofenac (100 mg) resulted in statistically significant increase in onset of action for both the anesthetic agents. There was no significant difference in the time of onset of anesthesia between the two local anesthetic solution (chi-square test/ One way ANOVA).
ABSTRACT
A 24 year old male was referred with pain and swelling in relation to a previously root canal treated maxillary left lateral incisor. Radiographic examination revealed presence of a second root which was left untreated in the previous treatment. This endodontic mishap had led to the failure of the case. During the retreatment the second canal was detected and cleaned, however considering the amount of bone loss around the second root, it was resected. This case report demonstrates the need for greater attention in treating the root canal of maxillary lateral incisors due to its anomalies, and also the need for thorough evaluation of good quality preoperative radiograph to avoid such mishaps.
ABSTRACT
The method of finite elements was developed at perfectly right times; growing computer capacities, growing human skills and industry demands for ever faster and cost effective product development providing unlimited possibilities for the researching community. This paper reviews the basic concept, current status, advances, advantages, limitations and applications of finite element method (FEM) in restorative dentistry and endodontics. Finite element method is able to reveal the otherwise inaccessible stress distribution within the tooth-restoration complex and it has proven to be a useful tool in the thinking process for the understanding of tooth biomechanics and the biomimetic approach in restorative dentistry. Further improvement of the non-linear FEM solutions should be encouraged to widen the range of applications in dental and oral health science.
