This descriptive type of cross-sectional study was conducted with the aim to find out the students’ perceptions on educational environment of selected dental colleges in Bangladesh. The study was carried out in ten selected dental colleges (4 government & 6 non-government) of Bangladesh. Total sample size was 1169 of different years of BDS students. Dental colleges were selected purposively & data was collected from students by adopting convenience sampling technique. Data collection was done with self-administered semi-structured questionnaire with two open questions using Dundee Ready Educational Environment Measurement (DREEM) inventory with some modification. There were five subscales of DREEM for students. Study results revealed that total DREEM score of students were 142. Mean score of students’ perceptions by subscale of DREEM were “students’ perception of their learning (34.95); students’ perception of their teachers (30.36); students’ academic self-perception (24.94); students’ perception of educational atmosphere (32.82) and students’ social self-perception (18.83). All these values indicated that the students’ perception were in the right & mostly positive direction. Study recommended that significant attention should be paid in few problematic areas specially for “too much teacher centered learning and over emphasized factual learning. Study also recommended to improve the logistic support for students of dental colleges to ensure better educational environment of Bangladesh.

Background: Lidocaine Adrenaline Combination (LAC) in saline (Jungle juice) is used to provide perioperative analgesia, blood conservation and separation of tissue planes. It comprises 20 ml of 2% lidocaine, 80 ml of sterile saline and 0.5 ml of 1:1000 adrenaline solution. This study aimed to evaluate knowledge and safe usage of jungle juice on patients. Objective: To stablish formulation, extent of usage, patterns & safety measures employed during use of jungle juice among surgical teams. Methods: This prospective case control study was carried out in Obstetrics & Gynecology department of Ad-din Akij Medical College & Hospital, Khulna from March 2014 to June 2018. Patients were divided into two groups. In the control group, no paracervical infiltration was given. In the experimental group, paracervical infiltration was given before hysterectomy. The operating time, blood loss and post-operative infection were noted in each group. Results: The mean operating time was higher (59.18 minutes) in vaginal hysterectomy and 60.93 minutes in fistula & perineal repair surgery without infiltration in comparison to the group with infiltration (P<0.05). There was significant difference in haemoglobin concentration & amount of blood loss after surgery between the groups. There was no case of infection in both groups. Conclusions: From our study, we concluded that paracervical infiltration provide perioperative analgesia, blood conservation & separation of tissue for ease of dissection.
