Abstract Purpose To assess the clinical and radiographic success rate of microsurgical endodontic treatment of upper molar teeth in relationship with the maxillary sinus, with 12 months follow-up. Methods Patients treated with microsurgical endodontic treatment of upper molar teeth in the period between 2017 and 2019 were recruited from two dental clinics according to specific selection criteria. The outcomes were determined based on clinical and radiographic results taken three, six and 12 months post-operatively, compared with those taken immediately before and after surgery. Clinical and radiographic outcomes were recorded. The distance between the most apical part of the root and of the lesion to the maxillary sinus was measured on CBCT images before the surgery. Patient-related outcomes were recorded. Results Out of 35 patients evaluated, 21 were selected according with the selection criteria for a total of 27 roots and 29 canals treated. After 12 months, 18 patients showed a complete healing whereas three demonstrated incomplete healing. Consequently, the success rate in this study was 85.7% after one year. In 28.5% (6 patients) there was a perforation of the Schneiderian membrane that didn’t seem to affect the outcome. All patients kept the molar one year later. The pain level decreased significantly over the time during the first week after surgery. Conclusion Microsurgical Endodontic treatment of the upper molar teeth should be considered a valid and predictable treatment option even in case of Schneiderian membrane perforation. Future clinical studies with a larger sample size are needed to compare the results obtained.

Causes Of Failure

Introduction: The radiographic control of the root canal treatment can evaluate the healing of the periapical lesions. The objective of this study was to determinate the characteristics of the radiographic healing that was observed after one year, during follow-up sessions; so, the healing of the lesions according to the periapical pathology at the beginning of the treatment and the causes of failure of the endodontic treatments were recorded.Method: This is a prospective, observational, descriptive and longitudinal study, carried out in patients who attended control one year after endodontic treatment through the Periapical Index (PAI).Results: A total of 395 teeth of patients who underwent endodontic treatment one year prior to data collection, 87 presented radiogaphically observable periapical lesions; of these, 40 (45.97%) attended the control at one year. The frequency of cases in which some degree of radiographic healing was observed one year after treatment was 97.46%. The pathology with more cases of complete healing was periodontitis with sinus tract. In general, 84.61% of the cases decreased two levels in their PAI after one year. The 100% of the cases of failure presented vertical root fractures.Conclusion: The frequency of periapical healing after endodontic treatment is high. The main cause for the failure of the treatments documented in this study was the lack of coronal restoration that caused vertical fractures.

Dental crown fractures in small animal pathology are common dental issues in every day practice. The most frequently performed procedure is extraction with all the negative consequences.The conservative approach to dental crown fractures involves endodontic treatment and coronal reconstruction in order to keep the fractured teeth on the dental arch.They were taken into study 74 dental crown fractures involving the pulp chamber, leaving the root undamaged.Clinical and radiological one-year check-up revealed us that the conservative approach to dental crown fractures in dogs and cats, when the selection criteria correspond to the indications of the specialized literature and when it is performed by latest protocols, is a reliable alternative to veterinary dental extractions.

Objective: The objective of this study was to compare the topical GTN andlateral internal sphincterotomy for the treatment of chronic anal fissure. Setting: This was a prospective randomizedcohort study conducted at Isra University Hospital, Hyderabad between September 2004 and August 2005. Materialand Methods: Fifty patients fulfilling the selection criteria were randomly divided into two equal groups. One group wastreated with topical glyceryl trinitrate (GTN) ointment and other group was treated with lateral internal sphincterotomy.Patients were followed up in outpatients department after regular intervals for about one year. The data was collectedand two groups were compared with special reference to pain relief, fissure healing and recurrence rate. Results: Painrelief was observed in 96% of the patients in GTN group as compared to 92% of the patients in sphincterotomy groupafter 6 weeks. Complete healing of fissure was observed in 92% of the patients in GTN group as compared to 88% ofthe patients in sphincterotomy group after 6 weeks. Recurrence was observed in 16% of the patients in GTN group ascompared to 4% of the patients in sphincterotomy group after one year. Conclusion: GTN and lateral internalsphincterotomy are comparable in terms of pain relief and fissure healing after 6 weeks. Topical GTN is suggested tobe the initial treatment whereas lateral internal sphincterotomy is suggested to be reserved for the patients notresponding to topical GTN or having recurrence after completion of treatment with GTN.

Seventy primary molar teeth, carious exposed, symptom free, without any sign of root resorption in children aged from 3 to 6 years (main age 4.3yr) were treated with conventional pulpotomy procedures. Ferric sulfate 15.5% solution (applied for 15 second for 35 teeth) and formocresol solution (five minute procedure of Buckley's formula for next 35 teeth) have been used as pulpotomy agents. In both groups, pulp stumps were covered with zinc-oxide eugenol paste. Permanent restorations were stainless steel crowns. Clinical check up was every three-months and radiographic follow-up time was six and twenty months after treatment. Our results within this period revealed 100% clinical success rate in both groups. Radiographic success rate was in both groups 97.2%, while in 2.8% cases has shown internal root resorption. On the basis of these results, we can recommend ferric sulfate as a pulpotomy agent in primary teeth in substitution for formocresol at the moment.

Abstract Background Diabetic foot osteomyelitis (DFO) is a leading cause of below knee amputation (BKA). Even when medical treatment is deemed unlikely to succeed, patients with DFO are often resistant to amputation. Methods An observational cohort analysis was done on patients with DFO at Michigan Medicine who were evaluated by podiatry and recommended BKA from Oct 2015 - Jun 2019. Primary outcome was mortality after BKA recommendation. Secondary outcomes were healing of affected limb, rate of BKA or above knee amputation (AKA) and total antibiotic days in the 6 months following. All intravenous antibiotics and oral courses of linezolid and fluoroquinolones were captured. Results Of 44 patients with DFO, 18 chose BKA, 26 chose medical management with wound care. Mean age of the cohort was 61, 68% male, 80% white with a median Charlson Comorbidity Index of 6 (IQR 4,7). The two groups were similar with regards to demographics and comorbid conditions. Those who chose medical management did so because their infection was non-life-threatening and they desired to avoid amputation. One-year mortality was greater in patients who were medically managed compared to those who had BKA (23.1% vs 0%, OR 11.7, 95% CI 0.6–222.9). Considering only the 33 patients who were followed for at least 2 years, 2-year mortality was also greater in the medically managed group compared to the BKA group (38.5% vs 5.6%, OR 10.6, 95% CI 1.2–92.7, Figure 1). Fewer patients in the medical management group had complete healing of their wound/stump compared to the BKA group (46.2% vs 88.9%, OR 9.3, 95% CI 1.8–49.1). In the medically managed group, 18 (69%) patients went on to require BKA or AKA at a median of 76.5 days compared to 2 (11%) in the BKA group who required AKA at 1 and 11 days following recommendation. Median antibiotic days were significantly greater in the medically managed group compared to the BKA group (55 IQR 42,78 vs 17 IQR 10,37, p=0.0017). Conclusion In this cohort of DFO patients where BKA was recommended, medical management was associated with increased mortality, poor healing of the affected limb, and excess antibiotic exposure compared to BKA. These findings are particularly notable as case mix and severity of illness were similar between the two groups. This study can be used to inform providers and patients in cases where BKA is recommended. Disclosures All Authors: No reported disclosures

Abstract Background The presence of septa increases the risk of Schneiderian membrane perforation during sinus lift procedure, and therefore, the chance of graft failure increases. We present a safe method of managing septa and, in particular, overcoming small and palatally located septa. Methods After the elevation of the flap and the creation of a small bony window positioned anterior to the septum, the Schneiderian membrane is lifted carefully. A thin and narrow osteotome is then placed at the indentation created at the base of the septum, and mobilization of the septum is achieved by gentle malleting. The membrane is again carefully lifted up behind the septum. Results There was one small membrane perforation case in all 16 cases, and none of these patients showed postoperative complications such as implant failure, infection, or maxillary sinusitis. Conclusions This technique is useful for overcoming the problem of maxillary sinus septa hindering the sinus floor elevation procedure, leading to fewer complications.

Mucosal Thickening

Background: Various parameters are known to affect the amount and type of mucosal thickening. The aim of this retrospective study was to investigate these effects through a survey of cone-beam computed tomography (CBCT) images. CBCT scans of 150 patients, which included the area of the MS and maxillary teeth (canine, first premolar, second premolar, first molar, second molar, and third molar), were evaluated retrospectively for the presence of sinus mucosal thickening. The parameters evaluated as possible causes of mucosal thickening were age, sex, tooth type, proximity to the maxillary sinus, endodontic treatment, and periapical lesion. Descriptive statistics and multiple logistic regression were used to analyze the data. A total of 28% of the teeth presented with mucosal thickening, which was associated with periapical lesions in 57.1% of 77 cases. The size of the lesion was the only parameter that was found to be significantly connected to the presence of mucosal thickness. More than 50% of teeth with periapical lesions in the posterior maxilla exhibited mucosal thickening. Other parameters such as age, sex, and the position of the root tips in relation to the MS floor did not influence the probability of developing mucosal thickening.

Endodontic microsurgery is a highly predictable treatment option in most cases when conventional endodontic treatment is not feasible. Nevertheless, mandibular molars are still considered by clinicians to be the most difficult type of teeth, with the lowest success rate. In recent years, endodontic microsurgery has been attempted more frequently with the emergence of modern cutting-edge technologies such as dental operating microscopes, various microsurgical instruments, and biocompatible materials, and the success rate is increasing. This review describes the current state of the art in endodontic microsurgical techniques and concepts for mandibular molars. Notably, this review highlights contemporary equipment, technology, and materials.
