Abstract

Aims : the study aims is to examine the inter- observer variability in radiographic interpretation of the variable position , shape and appearance of mental foramen. Materials and Methods: Four examiners, two dental radiologists and two oral surgeons evaluated 30 panoramic radiographs to evaluated the position, shape and appearance of mental foramen. Results: The most frequent position of mental fo-ramen was between first and second premolars then followed by those below the apices of the first and second premolars and the most frequent shape of mental foramen was irregular where separated type is the frequent appearance of mental foramen. For agreement there was no significant difference between two radiologist for position ,shape and appearance of mental foramen , but with a significant difference was found between four observer, for the position of mental foramen. Conclusions: The study concluded that the position of mental foramen is most commonly below and between the pre-molar teeth and the most frequent shape are irregular and appearance separated type

Abstract

Aim: The present study compares the accuracy of conventional and digitalradiographic system in the determination of apical fitness in endodontic therapy.Method: Thirty three root canals of first upper and lower molar teeth were used inthis study; a K-file was inserted into the canal until its tip was fit snuggly onemillimeter shorter than the apex. Each tooth was radiographed twice with twodifferent radiographic systems; conventional & digital systems. The right-angleparalleling technique with film holders was used in both systems. The distancebetween the file tip and the center of radiographical apex from both imaging systemswas measured by two examiners and the mean of each two measurements wasrecorded, the data was collected and analyzed statistically by paired t- test.Results: The mean value of radiographic length reveals that there is a very smalldifference between the measurements of conventional radiographic system(0.8727mm) and those measurements of digital radiographic system (0.8367mm)when compared with the real length measurements (1mm). Paired t-test showsthat there is no significant difference (p < 0.05) was founded between the realmeasurements and the radiographic measurements are taken from both conventionaland digital systems. In conclusion both the conventional and digital imaging systemscan be used accurately for working length determination in an endodontic therapy.

Abstract

Background: Hemorrhoidectomy by LigaSure electrosurgical unit seems to be very effective treatment and results in better surgicaloutcomes when compared with the conventional excisional hemorrhoidectomy. Objective: The aim of this study was to compare thefeasibility and the surgical outcomes of LigaSure hemorrhoidectomy with that of conventional diathermy excisional hemorrhoidectomy.Materials and Methods: Patients characteristics were comparable in both groups. Ninety six patients with symptomatic mainly grade III andIV piles were randomized for either conventional excisional hemorrhoidectomy (48 patients) or to LigaSure hemorrhoidectomy (48 patients)for the period from April 2014 to July 2016. The surgical outcomes of both procedures including the operative time, intra-operative bloodloss, postoperative pain, analgesic requirements, early and late postoperative complications, wound healing, recovery time and return towork, recurrence and patient satisfaction were recorded, compared and evaluated. Results: The mean operative time and amount of intraoperativeblood loss were significantly lower in LigaSure hemorrhoidectomy group. Postoperative pain and need for parentral analgesiawere comparable in the first 24 -48 hours postoperatively, but they were significantly lower in LigaSure group after the second postoperativeday. Faster wound healing and early return to work were obviously noted among patient subjected to LigaSure hemorrhoidectomy. Earlypostoperative complications were lower in LigaSure group while late complications were comparable in both groups. Lastly, LigaSure groupshowed high satisfaction rate compared to conventional hexcisional hemorrhoidectomy group. Conclusion: LigaSure hemorrhoidectomy issuperior and more advantageous in term of operative time, blood loss, post-operative complications, faster wound healing and return to work.It is simple, feasible and easy to learn.

Abstract

This study was conducted to evaluate the histomorphological changes occurred during intestinal anastomosis performed by laparoscopic Vs conventional techniques in eighteen dogs, which were divided randomly into three groups. In group 1, intestinal anastomosis was performed extracorporeally by laparoscopic-assisted surgery, during which a loop of the small intestine was exteriorized through a mini-laparotomy opening and was surgically resected and anastomsed by simple interrupted sutures; in group 2, intestinal anastomosis was carried out by intracorporeal laparoscopic surgery; and in group 3, intestinal anastomosis was performed by conventional laparotomy. Intestinal biopsies were obtained from the site of anastomosis in all dogs at days 15 and 30 following the operation. Normal regeneration of the structural constituents of the intestine was observed 15 days following anastomosis in animals of the first and second groups compared to villous atrophy associated with delayed and partial regeneration of the intestinal mucosa that were manifested in animals of the third group. In addition, histopathological changes indicative of serosal adhesion were observed in two animals of the latter group. These results showed that intestinal anastomosis achieved by laparoscopic surgery revealed better and faster healing rates compared to intestinal anastomosis achieved by conventional laparoptomy

Abstract

Background: Sliding mechanics is widely used during orthodontic treatment. One of the disadvantages of thismechanics is the friction generated at the bracket/archwire interface, which may reduce the amount of desiredorthodontic movement obtained. The aim of the present in vitro study was to evaluate and compare the staticfrictional forces produced by two passive self-ligating brackets stainless-steel and hybrid and two conventionalbrackets stainless-steel and monocrystal ligated with stainless-steel ligature wire at two degrees of torque(zero andtwenty) under dry condition.Materials and method: One hundred and sixty brackets were used in this study divided into four groups each groupconsisted of forty brackets these are: Two self-ligating (stainless-steel and Hybrid) while the two conventional typesare the (stainless-steel and monocrystal).twenty of each group examined with 0.016"x0.022"archwire, ten at 0˚ torqueand ten at 20˚ torque while the other twenty of each group examined with 0.019"x0.025", ten at 0˚ torque and ten at20˚ torque.Results: There was a significant different between all groups except in case when self-ligating brackets (both types)ligated to both wires at 0˚torque there was no significant difference.Conclusions: The self- ligating brackets produce significantly lower static friction than the conventional types at bothdegrees of torque. There was no significant different between both self-ligating brackets at0˚torque while at 20˚torque the stainless- steel self –ligating produce lower static friction than the clear self-ligating type

Abstract

ULTRASONIC DISSECTION VERSUS CONVENTIONAL LIGATION COAGULATION IN THYROIDECTOMYAbdulameer Muhsin AldarajiMB, ChB, FICMS, General Surgeon, Al-Faiha General Hospital, Basrah, IRAQ.Abstract Ligation and diathermy coagulation was the standard method of hemostasis in thyroid surgery for more than a century. New hemostatic techniques were developed in the 1990th. Ultrasonic dissector used for the first time in thyroidectomy in 1999 by Tokami. Many studies compared the conventional method of thyroidectomy with new ultrasonic dissector technique. These studies found many advantages of the new method including reduction of operative time, shorter incision, decrease blood loss, decrease post operative drainage, shorten hospital stay and decrease complications. This study compared the two methods of hemostasis regarding incision length, operative time and complications. Between March 2012 and March 2015, 143 patients underwent open thyroidectomy involved in a prospective study at Al-Faiha General Hospital. The patients were divided into 2 groups: Group 1, conventional thyroidectomy technique(clamp, tie and diathermy coagulation) included 104 patients. Group 2, ultrasonic dissection technique (sutureless thyroidectomy) included 39 patients. The patient characteristic and postoperative complications were reported. The incision length and the operative time was measured. All patients underwent surgery by the routine pre tracheal strap muscle cutting transeversly (not splitting). In group 2, the ultrasonic dissector was used in strap muscle cutting, sealing &section of the blood vessels and in the final resection of the gland. The surgical incision length and operative time were compared in both groups. In lobectomy, there was no significant reduction in the length of incision with use of ultrasonic dissector( z value<1.96)(p >0.05), while in subtotal, total or near total thyroidectomy there was significant reduction in the length of incision (p value<0.05) with use of ultrasonic dissector. There was significant reduction of operative time (p value<0.05) in lobectomy and total or near total thyroidectomy with use of ultrasonic dissector as compared to conventional thyroidectomy technique. There was no significant difference in the complications in both techniques apart from increased incidence of temporary recurrent laryngeal nerve paralysis in ultrasonic dissector technique (9.2% in USDT v s 3.7% in CT of thyroidectomy). This study found significant reduction of the surgical incision size similar to that obtained by Fabrizo who stated that thyroidectomy can be done with shorter incision. This improve patient satisfaction and cosmetic outcome. The operative time was significantly reduced in lobectomy, total or near total thyroidectomy by the use of ultrasonic dissector technique(USDT) as compared to the conventional technique (CT){lobectomy 44 minutes vs 55 minutes, total thyroidectomy 57 minutes vs 80 minutes}. Similar results were obtained by many other studies such as Micoli et al & Siperstein et al. this may save utilization of operation theatre and decrease waiting list. The USDT is safe as far as the complication rate was similar to that of CT apart from increase the incidence of temporary recurrent laryngeal nerve paralysis. Many studies confirmed the safety of USDT such as that of Tokami, Micolli, Siperstein etc . In conclusion, thyroidectomy can be performed safely by the USDT with advantage of smaller incision & shorter operative time as compared to conventional technique.

A COMPARATIVE STUDY BETWEEN HARMONIC SCALPEL HEMOSTASIS AND CONVENTIONAL HEMOSTASIS IN TOTAL AND SUBTOTAL THYROIDECTOMYMohammed Salim Mohammed*, Jasim D Saud#, Mansour Amin Mohammed$ & Mazin H Al-Hawaz@ *MB,ChB, Board Candidate. #MB,ChB, FICMS, CABS, Consultant Surgeon, Basrah General Hospital. $MB,ChB, DS, CABS, MRCS, Lecturer, Dept. of Surgery, College of Medicine. @ MB,ChB, CABS, DGS, FRCS, Prof. of General Surgery, Basrah Medical College., Basrah, IRAQ.Abstract Thyroid gland is highly vascularized organ, so good hemostasis during total or sub-total thyroidectomy is crucial to decrease the complications and to improve the outcome. This study aimed to evaluate the advantages and disadvantages of using harmonic scalpel device in comparison with conventional hemostasis for total and subtotal thyroidectomy in terms of operative time, nerves injury, post-operative blood loss, hematoma development, hypocalcemia and length of hospital stay. This study included 80 patients who underwent total or subtotal thyroidectomy. They were divided into two groups according to the type of hemostasis: conventional hemostasis group and harmonic hemostasis group. Different diseases were included (multinodular goiter, toxic goiter and malignant diseases). The results showed that time of operation was significantly shorter in the harmonic hemostasis group (79.52±14.98 min) than conventional hemostasis group (100.92 ±10.64 min) with p value 0.0001, also post-operative blood loss was lower in harmonic hemostasis group (52.5±26.23 ml) than conventional hemostasis group (75.13±17.8 ml) with p value 0.0001. Other outcome such as recurrent laryngeal nerve injury, post-operative hematoma, post-operative hypocalcemia and length of hospital stay did not show significant difference between the groups. In conclusion, using harmonic scalpel device in total or subtotal thyroidectomy reduced the operative time and post-operative blood loss, without any change in the incidence of nerve injury, hematoma, hypocalcemia and the length of hospital stay.

Abstract

Background: The success and maintenance of indirect dental restorations is closely related to the marginal accuracy, which is affected by many factors like preparation design, using of different fabrication techniques, and the time of taking final impression and pouring it. The purpose of this in vitro study was to evaluate the effect of different pouring time of conventional impression on the vertical marginal gap of full contour zirconia crowns in comparison with digital impression technique.Materials and Methods: Forty sound recently extracted human permanent maxillary first premolar teeth of comparable size and shape were collected. Standardized preparation of all teeth samples were carried out to receive full contour zirconia crown restoration with deep chamfer finishing line all around the tooth with (1mm) depth, axial length (4mm) and convergence angle (6 degree). The specimens separated into two groups; Group A; eight specimens were scanned digitally by using Omnicam scanner; Group B; conventional impressions were taken for the remaining thirty two specimens and further subdivided to four groups according to the time of impression pouring; Group B1: PVS were poured after 30 minutes; Group B2: PVS were poured after 24 hours; Group B3: PVS were poured after 7 days; Group B4:PVS were poured after 14 days. Marginal discrepancy was measured at four points at each tooth surface. Sixteen points per tooth were measured using digital microscope at (180X) magnification. One-way ANOVA test and LSD test were carried out to see if there was any significant difference among the means of the conventional impression groups. Independent samples t-test was carried out to examine if there is any significant difference between digital and conventional impression technique.Results: group B2 had the least mean of marginal gap with statistically significant difference when compared to group B1 and statistically highly significant difference when compared to group B3 and B4. There was a statistically highly significant difference in the vertical marginal gap between digital impression technique and conventional impression.Conclusions: the pouring of conventional impression after 24 hours provides better marginal fit than other pouring time. The digital impression provides better marginal fit than conventional impression
