Mandibular Canine

Successful endodontic treatment depends upon the clinician’s precise knowledge and ability to manage complex internal anatomy in order to avoid failure during endodontic treatment. Mandibular canines normally have single root with centrally placed single canal and internal anatomy as simple as could be expected, but there are such canines with a single root with two canals, two roots or fused roots. The occurrence of two canal joining to one for a men may be a rare entity with 4-15% prevalence. Canine is the cornerstone of mouth due to its position and very important as abutment for any type of restoration, so long term success of the restorative depend directly on the quality of endodontic treatment. This article presents a case series of successful endodontic management of mandibular canine with two canals which merge into one canal with one foramina and mandibular canine with two roots and two canals.

Oesophagectomies and gastrectomies are performed predominantly for the treatment of malignant disease. However, in this case series, we describe three patients with benign disease who had a laparoscopic oesophagogastrectomy with gastroduodenal detachment and Roux-en-Y biliary diversion, and discuss the operative feasibility and consequent patient outcomes. Our aim was to modify the procedure using an established reconstruction already practised in gastric and bariatric surgery, thereby preventing operative sequelae that lead to a poor quality of life (eg reflux oesophagitis and vomiting). During the first postoperative year, our first two patients experienced weight loss, indigestion and lower bowel symptoms with no apparent improvement in gastric function compared with a standard gastric tube pull-up reconstruction. In the longer term, in both patients, the gastric tube interpositions appeared to function well and there was no evidence of gastro-oesophageal reflux disease, delayed gastric emptying or troublesome indigestion. Our third patient, who had lifelong severe reflux symptoms, was eating normally three months after the operation with no need for antacid medication. We therefore conclude that laparoscopic Ivor–Lewis oesophagogastrectomy with Roux-en-Y bypass is a more complex reconstruction with added risks but may in the long term result in better overall outcomes and satisfaction for patients, particularly those with benign disease.

Background The aim of this study was to examine the long-term outcomes of the modified endoscopic Lothrop procedure for the management of the most severe forms of recalcitrant chronic frontal sinusitis. Methods This case series evaluated 13 consecutive cases of the modified endoscopic Lothrop procedure for chronic frontal sinusitis from April 1996 to December 1999. Patent communication to the frontal sinus was evaluated by postoperative endoscopic exam. Postoperative patient symptomatology and medication requirements were assessed during clinic evaluation and by standardized telephone questionnaire. Results At a mean follow-up period of 34.5 months, a 77% patency rate was obtained, with 2 of the 13 patients requiring an osteoplastic flap with obliteration. Telephone questionnaire results indicate improved symptoms and decreased medication requirements in the majority of patients who maintained patency. Conclusions These results show that the modified endoscopic Lothrop procedure provides a good alternative to the osteoplastic flap with obliteration for patients with the most severe forms of chronic frontal sinusitis. Initially, high patency rates decline with longer-term follow-up, and severe forms of chronic rhinosinusitis continue to significantly impact patient-perceived quality of life in some patients. The modified endoscopic Lothrop procedure should be reserved for patients who have failed more conservative endoscopic approaches to the frontal recess.

ABSTRACT Introduction The study aimed to compare the shaping and preservation of the original curvature of simulated curved root canals using the following instruments: Reciproc (Rcp), WaveOne (Wo), and the ProTaper Next system (Ptn). Materials and methods A total of 45 resin blocks with simulated curved root canals were divided into three groups (n = 15), prepared using the Rcp (R25), Wo (25/0.8), and Ptn (X2) instruments. Standardized photographs were taken before and after canal instrumentation. After the superimposition of the images, the amount of resin removed from the curvature's inner and outer walls was measured at six apical levels, at intervals of 1 mm. The canals’ angles of curvature before and after instrumentation were subtracted. Results There were no significant differences between the instruments in terms of the total amount of resin removed of the inner or outer walls of the apical curvature (p > 0.05). The Rcp instruments provided the best resin removed ratios between the walls. The means of the change in angle were as follows: Wo = 2.15°, Ptn = 0.92°, and Rcp = 0.21°. WaveOne caused significantly higher deviations than Rcp. Conclusion All of the instruments demonstrated a tendency to straighten the simulated root canal. Instruments that use rotary movement achieved an effect similar to that of the reciprocating instruments in relation to change in angle. Clinical significance Deviations from the original shape of the root canal could have a negative impact on the quality of a filling and consequently on the success of the endodontic treatment.

Abstract BACKGROUND: Deep brain stimulation (DBS) to treat neuropathic pain refractory to pharmacotherapy has reported variable outcomes and has gained United Kingdom but not USA regulatory approval. OBJECTIVE: To prospectively assess long-term efficacy of DBS for chronic neuropathic pain in a single-center case series. METHODS: Patient reported outcome measures were collated before and after surgery, using a visual analog score, short-form 36-question quality-of-life survey, McGill pain questionnaire, and EuroQol-5D questionnaires (EQ-5D and health state). RESULTS: One hundred ninety-seven patients were referred over 12 years, of whom 85 received DBS for various etiologies: 9 amputees, 7 brachial plexus injuries, 31 after stroke, 13 with spinal pathology, 15 with head and face pain, and 10 miscellaneous. Mean age at surgery was 52 years, and mean follow-up was 19.6 months. Contralateral DBS targeted the periventricular gray area (n = 33), the ventral posterior nuclei of the thalamus (n = 15), or both targets (n = 37). Almost 70% (69.4%) of patients retained implants 6 months after surgery. Thirty-nine of 59 (66%) of those implanted gained benefit and efficacy varied by etiology, improving outcomes in 89% after amputation and 70% after stroke. In this cohort, >30% improvements sustained in visual analog score, McGill pain questionnaire, short-form 36-question quality-of-life survey, and EuroQol-5D questionnaire were observed in 15 patients with >42 months of follow-up, with several outcome measures improving from those assessed at 1 year. CONCLUSION: DBS for pain has long-term efficacy for select etiologies. Clinical trials retaining patients in long-term follow-up are desirable to confirm findings from prospectively assessed case series.

Purpose. Long-term evaluation of the visual refractive outcomes and the quality of life after implantation of the WIOL-CF (Medicem, Czech Republic) in both eyes. Design. retrospective, nonrandomized noncomparative case series. Methods. 50 eyes of 25 patients, including 11 women (44%) and 14 men (56%). The age range of the patients was 38 to 77 years (mean age 55.48 ± 10.97 years). All patients underwent bilateral implantation of the WIOL-CF. Exclusion criteria were previous ocular surgeries except for cataract surgery and refractive lens exchange, irregular corneal astigmatism of >1.0 diopter, and ocular pathologies or corneal abnormalities. Postoperative examinations were performed at 14 days and 3, 6, 12 months of surgery; the last follow-up was between 24 and 36 months after the procedure. All exams included manifest refraction, monocular uncorrected visual acuity (UCVA) and distance-corrected visual acuity (DCVA) in 5 m (Snellen), monocular uncorrected visual acuity in 70 cm and 40 cm (Jeager) and binocular UCVA, DCVA in 5 m, 70 cm, and 40 cm, binocular contrast sensitivity (CS) under photopic conditions, binocular defocus curves, high-order aberrations, quality-of-vision VF-14 questionnaire, and spectacle independence. Results. Significant improvement in monocular visual acuity at all distances was demonstrated; the mean postoperative spherical equivalent was 0.32 ± 0.45D. The postoperative means of binocular distance UCVA and BCVA were also improved ( p  < .001) and so were the mean uncorrected intermediate VA (2.053 ± 1.268) and near uncorrected VA (2.737 ± 1.447). There was a significant improvement in contrast sensitivity at all spatial frequencies and higher-order aberration, compared to preoperative results. Conclusions. The evaluation of a WIOL-CF showed good distance, intermediate, and near visual acuity. Contrast sensitivity increased after surgery in all spatial frequencies. Patient satisfaction was high despite some optical phenomena. The rate of postoperative spectacle independence also turned out high. Financial Disclosure.

Subject. Pulp tissue diseases are characterized by a wide prevalence, which makes it possible to consider the quality of endodontic dental treatment one of the most urgent problems of modern dentistry. High-quality treatment of complicated forms of caries is the prevention of odontogenic inflammatory processes, which include periodontitis, periostitis, osteomyelitis, abscess and phlegmon. Therefore, new tools and methods of treatment of complicated forms of caries are proposed, aimed at long-term preservation of teeth as a functional unit of the dental system. Objective: to analyze modern laser technologies in the treatment of complicated forms of caries. Materials and methods. The study was based on the search and study of original articles on the endodontic treatment of complicated forms of caries using laser radiation in the databases: Russian state library, eLibrary, PubMed, the Cochrane Library, Google Scholar. The main selection of materials was carried out by keywords. Results. The literature review describes the positive properties of laser radiation, its mechanism of action, the basics of its use in endodontic treatment, and its application in various branches of dentistry. Conclusions. Analyzing the literature data, we can conclude that the use of laser technologies in the treatment of complicated forms of caries is promising. It is possible to achieve high-quality cleaning of the root canal system and the best long-term results. However, the literature does not sufficiently cover the use of Er, Cr:YSGG laser with a wavelength of 2780 nm in the treatment of purulent pulpitis and pulp necrosis. In addition, taking into account the possibility of using lasers at a therapeutic appointment, it is possible to significantly improve the professional level of a dentist, improving the quality of dental care, reducing the number of complications and preventing various dental diseases.

Low Incidence

Introduction. Success in endodontic treatment depends upon the clinician's knowledge and ability to recognize and diagnose the presence of anatomical and morphological variations of the root and canal system. Mandibular canines are usually recognized as having one root and one root canal. In spite of the low incidence of mandibular canines with one root and two canals, their appearance should not be neglected due to the fact that the presence of a second canal in these teeth leads to difficulties in endodontic treatment. The aim of this case report is to describe mandibular canine with two root canals. Case presentation. 45-year-old patient presented for medical care due to the pain in a lower right canine. Clinical and radiographic examination revealed composite filling and caries with periapical radiolucent area and sensitivity to percussion in the mandibular right canine. By careful evaluation of the diagnostic radiology, it was observed that the mandibular canine had two canals. The patient was diagnosed with acute apical periodontitis and root canal therapy was given following the standard protocols. Conclusion. Although the prevalence of two canals in mandibular canine is low, the clinician should always be mindful of variations in the number of canals for appropriate therapeutic management.

Regenerative Endodontic Treatment

Traumatic dental injuries are particularly common in school-age children and often occur in the anterior region. Process management of cases is possible with alternative treatments according to the root development levels. This case series is aimed to present the treatment and 2-year follow-up of permanent anterior teeth with traumatic dental injuries. Case 1: An 8-year-old patient, who had a bicycle accident 20 days earlier, was diagnosed with extrusion of #31. Due to late admission to the clinic, no repositioning procedure was applied to the tooth. Regenerative endodontic treatment was performed. During the radiological follow-up, the apex was closed in the 12th month; however, it was observed that obliteration started in the root canal at the 24th month. The case is still being followed up at regular intervals. Case 2: A 13-year-old patient, who had a traffic accident 3 days prior, was diagnosed with subluxation in #11, and a root fracture was detected in the apical third of #21. In #21, root canal treatment was applied to the coronal part of the fragments. After the diagnosis of pulp necrosis in #11 in the 2nd month of the follow-up period, root canal filling was applied. During the follow-up period, no pathology was detected and no granulation tissue was formed between the fragments in #21. In traumatic dental injuries, long-term follow-up, well-timed endodontic treatments, and material selection play an important role in success. With regenerative endodontic treatment, successful results can be obtained even in treatments applied in late-admitted patients.

Aim: Endodontic surgery is a treatment for persistent peri-radicular pathological conditions that do not improve after endodontic treatment. The aim of this study was to evaluate the quality of endodontic treatment, technical error types seen in root canals and the periapical condition of the teeth in patients undergoing periapical surgery, and thus to analyze the reasons leading to periapical surgery. Methodology: Clinical and radiographic data of 301 periapical surgery cases were retrospectively evaluated in this study. The causes of periapical surgery were classified into technical and biological reasons. Results: In this study, 51.8 % of periapical surgery cases were related to biological factors and 48.2 % were related to technical factors. Maxillary anterior teeth were the most common teeth undergoing apical surgery with a rate of 66,8 %.  The most common technical reasons were non-homogeneous filling (15,6 %), underfilling (12,0 %) and overfilling (9,6 %). The most common biological reasons were cysts (30,2 %), traumas (16,6 %) and apical abscess (5,0 %).  37.5% of cases undergoing periapical surgery, the diameter of the cystic lesion was 10mm or more. Conclusion: The number of cases of apical periodontitis is increasing in the community due to insufficiently filled root canals. Increasing the quality of root canal treatments applied by dentists will reduce the need for periapical surgery by reducing the incidence of apical periodontitis.   How to cite this article: Ekici Ö.
