Irreversible Pulpitis

Root canal therapy linked to pulpal diseases or trauma is common in modern dental care. The 2% Lidocaine which is considered as the gold standard has some drawbacks in pulpal anaesthesia. Ropivacaine has beneficial anaesthetic effects on pulpal anaesthesia. Therefore, it is of interest to compare and evaluate the pulpal aesthetic effect using 0.5% Ropivacaine and 2% Lidocaine in symptomatic irreversible pulpitis. A double blinded randomized controlled clinical trial consisting of 110 lower molar and premolar tooth with irreversible pulpitis cases for root canal therapy were selected and randomly divided into 2 groups. Group A: 2% lidocaine with epinephrine and Group B: 0.5% ropivacaine. The pulp sensibility tests with heat test, cold test and electric pulp test were completed. The preoperative pain score was measured with Visual Analogue Scale (VAS) pain scale. Classical inferior alveolar nerve block (IANB) technique was given to all patients by a single operator. Subjects were asked for lip numbness and presence or absence of lip numbness. Postoperative pain scores were recorded during access opening and on placing files in the canal. There is no statistical difference between the groups during pre operative conditions. The mean pain scores within group A and group B is recorded. The difference was found to be statistically significant with p value ≤ 0.05. Significant difference between the mean values after and before the treatment is observed. However, there is no statistical significance between the mean pain scores between the access and pulp. The 0.5% Ropivacaine and 2% Lidocaine with epinephrine does not have any significant difference during access opening. However, 0.5% Ropivacaine groups were effective while placing the file in the canal. Thus, 0.5% Ropivacaine showed better results even though it was not statistically significant for further consideration in this context.

Endodontic Pain if occurs after few hours or days after the treatment indicates a poor pathosis and a bad prognosis in long term, due to this a newer generation of instruments for canal treatment has been introduced from Ni-Ti alloy which has even better ability to shape narrow and curved root canals, without causing aberration. To compare the mean postoperative pain score after manual SS (stainless steel) K-files and mechanical Ni-Ti rotary path files in patients with irreversible pulpitis. Study Design: Randomized controlled trial. Setting: Department of Operative Dentistry, Altamash Institute of Dental Medicine, Karachi. Period: 6 months from 01-10-2017 to 30-03-2018. Materials and Methods: Total 60 patients of irreversible pulpitis with moderate pain score ≥5 were included and divided equally in manual stainless-steel k-files and mechanical Ni-Ti rotary path files groups. Treatment was started with local anesthesia. Patients were recalled after 24 hours and the level of postoperative pain was examined. T-test was applied to compare the outcome in both groups. Stratification was done using t-test and P value ≤0.05 was significantly considered. Results: The mean pre-treatment VAS in group-A and group-B was 7.16±1.44 and 7.86±1.38 respectively. Mean post-treatment VAS in group-A and group-B was 2.33±1.02 and 1.10±0.66 respectively. A significant difference between the pre and post op pain was noted between the two groups, when compared after 24hours by using VAS. Conclusion: Mean post-operative pain score was significantly less with NiTi rotary path files as compare to manual stainless steel K-files.

Abstract Background: Cone-beam computed tomography (CBCT) was employed to study the morphology and curvature of middle mesial canals (MMCs) of mandibular first molars (MFMs).Methods: CBCT scanning was performed on MFMs of 1100 patients. Patients' images that met the inclusion criteria were divided into group A (<40 years old) and group B (≥40 years old) for further study. The images were used to study the incidence of MMCs at different ages, measure the curvature of MMCs in the mesiodistal and buccolingual directions using the Schneider method, and observe the anatomical morphology of the mesial root canal system. All statistical analyses were performed by using SPSS 21.0 software. Quantitative data were presented as mean ± standard deviation. Student’s t-test was used to calculate the statistical significance. P<0.05 was considered statistically significant.Results: In 875 patients, 1750 MFM images met the inclusion criteria. Among these cases, 158 MFMs contained an MMC, yielding an incidence rate of 9.03%. The incidence rate of MMCs was 11.22% in group A and 6.61% in group B, and this difference was statistically significant (P<0.05). The curvature in the mesiodistal direction was 29.39±8.53º in group A and 26.06±8.50º in group B, and this difference was also significant (P<0.05). The curved regions in groups A and B were often located in the middle 1/3 of canal. No significant difference in the distance between MMC orifices and mesiobuccal canal orifices or mesiolingual canal orifices was noted (P>0.05). The most common mesial root canal morphological type was type II (3-2) (53.80%). Conclusion: The incidence of MMCs in MFMs declined as age increased. The canal systems of MMCs were varied and complex, mainly exhibiting an obvious mesiodistal curve. CBCT is an outstanding method to help guide root canal therapy.

Background: It is important to control the pain associated with root canal treatment (RCT) in endodontic. Pain accompanying fear and anxiety due to endodontic treatment can be reduced by anesthetic techniques. The present study aims to compare the effect of articaine versus lidocaine local anesthesia for inferior alveolar nerve block (IANB) and long buccal nerve block on pain during RCT. METHODS: Twenty patients diagnosed with symptomatic irreversible pulpitis of mandibular posterior tooth were selected. The patients randomly received either cartridge of lidocaine or articaine using IANB and long buccal nerve block. The patients were randomly divided into two groups of ten. Group 1: patients received IANB and long buccal nerve block 2% lidocaine with 1:100000 epinephrine. Group 2: patients received IANB and long buccal nerve block with 4% articaine with 1:100000 epinephrine. Before the Injection, the patient received all information about the visual analysis scale (VAS). Pain was evaluated using VAS scale in numberic value 1 to 10 number. The pain was evaluated at three different stages: before administration of LA, after immediate access opening, and after immediate obturation procedure. Data were analyzed using various suitable statistical tests. RESULT: The mean value of efcacy of pain before administration of local anesthesia (LA) was 8.50 ± 0.97 for lidocaine and 8.30 ± 0.48 for articaine had no signicant difference. A signicant difference was observed at two different duration after immediate access opening and after immediate obturation where articaine has a lower mean value 3.60 ± 1.08 and 1.60 ± 0.17 respectively (P>0.05) as compared to the mean value of lidocaine 4.10 ± 1.10 and 1.60 ± 0.17 respectively Conclusion: Within the limitations of the study, in cases of symptomatic irreversible pulpitis articaine 4% did not alleviate pain much and showed better anesthetic efcacy than 2% lidocaine with IANB and long buccal nerve block.

Category: Bunion Introduction/Purpose: Kirschner-wires fixation, sometimes we have encountered pin irritation or pull-out. This is the reason why we consider additional fixation. Moreover, there are few reports according to comparison of fixation method, and Most of them focused on comparison K-wires or screw fixation only. Purpose of study is to compare clinical and radiographic outcome between Kirschner-wires only and combined screw fixation. Methods: The study included two different groups according to fixation methods. One with Kirschner-wires fixation (KW group) included 117 feet(of 98 patients), the other with combined screw fixation (KWS group) 56 feet (of 40 patients) with moderate to severe hallux valgus. Clinically, the preoperative and final follow-up visual analog scale (VAS) pain scores, the preoperative and final follow-up American Orthopaedic Foot & Ankle Society (AOFAS) hallux metatarsophalangeal (MTP)-interphalangeal (IP) scores, and patient satisfaction after the surgery were evaluated. Radiographically, the hallux valgus angle (HVA), intermetatarsal angle (IMA), medial sesamoid position (MSP), and first to fifth metatarsal width (1-5MTW) were analyzed before and after surgery. Results: The mean AOFAS score improved preoperative 65.5 to 95.3 at final follow up in group A, while preoperative 56.5 to 88.6 at final follow up. Pain VAS decreased from 5.7 to 0.5 in group A, whereas from 6.2 to 1.6 in group B. The mean HVA all improved from preoperative 38.5 to 9.3 at final follow up in group A and 34.7 to 9.1 in group B. The mean IMA and MSP also improved significantly at final follow up. In comparative analysis, the IMA did not show significant difference between postoperative and final state in group A, while showed significant increase in group B. Conclusion: We achieved favorable clinical and radiographic outcomes with minimal complications in patient with moderate to severe hallux valgus in both groups. However, this study shows no statistically significant difference in IMA during follow-up period and lower recurrence rate. Therefore we need to consider combined fixation method to provide better stability and can expect lower recurrence rate.

Abstract Background Roux en Y gastric bypass (RYGB) surgery for morbid obesity is considered as gold standard, but there can be a difference in the length of alimentary and biliopancreatic limb to achieve optimum weight loss. Till now there is no agreed consensus on the ideal limb lengths and their effect on the weight loss. We would like to evaluate the change in the alimentary limb length on the weight loss after the gastric bypass surgery,  as a short to medium term single center study. Methods A retrospective analysis from prospectively maintained   database of 523 patients who underwent RYGB from  2012 till 2018 was done. Patient who had at least a follow up of 2 years(n = 388) were included.  At our center we use alimentary limb of 120 +/- 10 cm for Body Mass Index (BMI) &lt; 40 kg/m2 (group A)  and 150+/-10 cm for the BMI &gt;40 kg/m2  (Group B). The biliopancreatic limb length varies from 50 to 70 cm and this does not change with BMI.  The percentage excess weight(EWL) loss was measured and analyzed  at 1st  and 2nd year post operatively. We used paired t test to check for statistical significance. Results There were 172 patients in Group A and 216 in Group B. The number of females were 330 and  males were 58.   The average age was 44 years .  The mean  preoperative  BMI for the 120 cm limb group was  37.1 kg/m2 and  that for  150 cm limb was 45.3kg/m2. The EWL for the group A at 1 year and 2 year post op was a  Mean and standard deviation  of 79.3% +/- 39.4% and 78.3% +/- 35.2% respectively and for group B was 58.8% +/- 26.6% and 58.6% +/- 23.2% respectively. The difference was statistically significant (p &lt; 0.001) . The analysis and interpretation for metabolic syndrome is yet to be determined.   Conclusions In our study, Increasing the alimentary limb length for higher BMI reduced  EWL. This is consistent with few other publications regarding the same. This has resulted in a  change in our practice namely keeping the length of alimentary limb constant and varying the BP limb length. We will be analyzing  and presenting this data in future.

The aim of our study to determine the role of tolvaptan in prevention of hyponatremia in transurethral resection of prostate surgery. This is randomized double-blind study conducted in 60 ASA grade status 1 and 2 patients age group between 45-80 yrs undergoing TURP under spinal anaesthesia in urology operation theatre in Mahatma Gandhi hospital Jaipur after receiving permission from hospital ethical committee. A detailed history, complete physical examination and routine investigation were done for all patients followed by informed written consent was obtained. Patients are randomly divided into 2 groups. In group A -30 patients who received orally tab tolvaptan 15 mg and group B-30 patients who received orally tab multivitamin 2 hrs before surgery after doing electrolytes of the patients in the morning. In both groups age (in yrs), wt (in kg), ASA grade, volume of irrigating fluid (in litres), volume of prostate resected (in gm) and duration of surgery (in minutes) all demographic and surgical details data were compared. Electrolytes were compared in both groups pre and post-operatively and statistical analysis was done.There was significant difference in post-operative sodium level between the two groups (A and B). The mean level of sodium significantly reduced post-operatively in group –B (control grp). The mean level of sodium significantly increased post-operatively in group –A (tolvaptan grp). We conclude single dose of tolvaptan -15 mg found to effective in prevention of hyponatremia in patients undergoing TURP.

Abstract Background: A retrospective study investigated and compared the results of a lamina withspinous process (LSP) and an iliac graft (IG) as bone grafts in single-segment lumbar pyogenic discitis (LPD) through one-stage-posterior-only approach with radical debridement and internal instrumentation.Methods: Data from 37 patients were reviewed. A LSP was placed in 17 patients (group A), and an IG was implemented in 20 patients (group B). The surgery time, surgery hemorrhage, hospital stay, drainage, and follow-up (FU) were reviewed. The visual analogue scale (VAS), Oswestry Disability Index (ODI), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) level, segmental angle, intervertebral height and bony fusion time were compared preoperatively and at the final FU.Results: All patients were followed-up for a mean of 27.94±2.35 months in group A and 30.29±1.89 months in group B, without a difference. The mean age was younger in group A than in group B (P<0.05). The surgery time, surgery hemorrhage, and hospitalization cost were lower in group A than in group B (P<0.05), except for the hospital stay and drainage time. Fever occurred in 10 patients in group A and 12 patients in group B. The ESR, CRP level, and VAS and ODI scores were significantly decreased, and there were no significant differences between the groups at the final FU. The distribution of bacterial agents in blood culture was 1 case of Aerobacter cloacae, 2 of Staphylococcus aureus, 2 of Escherichia coli, and 1 of Streptococcus viridis in group A and 1 of S. aureus，1 of Staphylococcus warneri and 2 of Klebsiella pneumoniae in group B. Pyogenic infection was observed in the pathological findings of all patients. No significant difference was found in the mean segmental angle or mean intervertebral height preoperation and at the final FU between the groups.Conclusion: The use of LSP as a new bone graft is reliable, safe, and effective for surgical management for the LPD while surgery is proposed as a good management strategy for LPD in carefully selected patients.

Apical extrusion of debris (AED) by the full sequence of the self-adjusting file (SAF) system was compared with that of the XP-endo shaper plus sequence. Sixty permanent mandibular incisors were randomly assigned to two groups (n = 30) for root canal instrumentation: Group A: Stage 1—pre-SAF OS, pre-SAF 1 and pre-SAF 2 files, followed by Stage 2—1.5 mm SAF; and Group B: Stage 1— hand K-file 15/0.02, followed by Stage 2—XP-endo shaper and Stage 3—XP-endo finisher. The AED produced during instrumentation at each stage was collected in pre-weighed Eppendorf tubes. The weights of AED by the two methods were compared using t tests with significance level set at 5%. Group A produced significantly less total AED than Group B (p < 0.001), with no significant difference in debris extrusion between the two stages (p = 0.3014). Conversely, in Group B, a significant difference was noted between Stage 1 and Stages 2 and 3 (p < 0.01), with no significant difference between Stages 2 and 3 (p = 0.488). Both sequences resulted in measurable amounts of AED. Each phase, in either procedure, made its own contribution to the extrusion of debris.
