Nonsurgical Management of Apical Root Perforation Using Mineral Trioxide Aggregate

This study illustrates a conservative approach to nonsurgical management of apical root perforation in maxillary first molars. A patient was referred for retreatment of a maxillary left first molar. Her chief complaint was dull pain while biting in her maxillary left first molar. Periapical radiography showed radiolucency related to the mesiobuccal root and overextended gutta-percha through a perforation in the apical part of the distobuccal root. A CBCT scan was acquired and revealed the location and size of the apical perforation. The clinical examination showed that the tooth has been endodontically treated and the canals were filled, tender to percussion and palpation. Thus, the nonsurgical root canal retreatment was done and the perforation site was repaired by using mineral trioxide aggregate (MTA). At the one-year follow-up, after the management of apical root perforation, we observed periapical tissue healing and no pain due to percussion and palpation, without any clinical/radiological signs or symptoms. The prognosis of this case has a higher success rate with the development of new materials such as MTA. The MTA not only can seal the site of the perforation but also has the ability to induce calcification. Many factors can contribute to the success rate of perforated cases, including time, size, and location of the perforation. With the use of this material and good tools like a microscope, there are those with having higher chances of repair and eventually higher success rates.

Dens invagination (DI) is a dental anomaly that can cause pulpal and periapical pathoses of the affected tooth. We describe the treatment of a healthy 18-year-old female with a chief complaint of recurrent facial swelling pertaining to a peg-shaped maxillary lateral incisor with DI. Examinations showed necrosis of the involved tooth with symptomatic apical periodontitis. Cone-beam computed tomography corresponded to Oehlers type II DI. Orthograde endodontic treatment was performed. To completely debride the canal and resolve the persistent purulent discharge, various methods and medicaments were used in separate sessions including passive ultrasonic activation of 5.25% sodium hypochlorite solution, calcium hydroxide mixed with 2% chlorhexidine, and double antibiotic paste as intracanal medicament. After resolution of the symptoms, the root canal and the invaginated space were filled by a mineral trioxide aggregate plug and backfilled with thermoplasticized gutta-percha. At the one-year follow-up, complete bone healing was noted in the affected periradicular area.

ObjectiveNeuroendoscopic surgery in children has particular features and is associated with different success rates (SR). The aim of this study was to identify putative factors that could influence the outcome in pediatric patients.MethodsClinical data of 177 patients under 18 years of age submitted to 200 consecutive neuroendoscopic procedures from January 2000 to January 2010 were reviewed.ResultsThe overall success rate was 77%. Out of the patients with successful outcomes, 46% were under six months, 68% were between six months and one year of age, and 85% older than one year. Neuroendoscopic techniques provide very good results for a wide number of indications in children. Tumor-related cerebrospinal fluid (CSF) circulation problems and aqueductal stenosis seem to be particularly well suited to neuroendoscopic treatment regardless of the patient's age.ConclusionPatients' age and etiology of hydrocephalus were associated with a different outcome. In all cases, surgical experience is extremely important to reduce complications.

Abstract Background Pulpotomy is one of the most widely used methods in preserving vital pulp in teeth, which is of great significance in achieving continue root formation in immature permanent teeth suffering from dental caries or trauma. The aim of this meta-analysis and systemic review is to synthesize the available evidences to compare different pulpotomy dressing agents for pulpotomy treatment in immature permanent teeth. Methods Electronic databases including MEDLINE (via Pubmed), EMBASE, the Cochrane library (CENTRAL) and the clinicaltrials.gov database were searched. The references of all included articles or relevant reviews were cross-checked. Only randomized controlled trials (RCTs) comparing two or more pulp dressing agent in permanent teeth with open apex would be included. Also, the studies should have at least 6 months of follow-up, report clinical and radiographic success in detail and publish in English. Results Five RCTs were included for a systematic review, and all of them had a high risk of bias. There is little difference in success rate between mineral trioxide aggregate (MTA) and calcium hydroxide (CH) at 6-month follow-up (risk ratio (RR) 1; 95% confidence interval (CI) 0.94 to 1.06) and 12-month follow-up (RR 1.04; 95% CI 0.96 to 1.13). There is no difference between MTA versus platelet-rich fibrin and MTA versus calcium-enriched mixture (CEM). There is only weak evidence of increased success rate in using MTA and triple antibiotic paste (TAP) rather than abscess remedy. Conclusions Based on the present evidence, similar success rates with MTA were found between the dressing agents CH, CEM, RPF and TAP as pulpotomy-dressing agents in the treatment of immature permanent teeth. More high-quality RCTs are needed in this field in future studies.

Purpose. To compare the surgical outcome of combined phacoemulsification and endoscopic cyclophotocoagulation (phacoECP) versus combined phacoemulsification and mitomycin C-augmented trabeculectomy (phacoTbx) in patients with coexisting glaucoma and visually significant cataract. Methods. A retrospective review of 89 eyes of 89 patients who received phacoECP (N=49) and phacoTbx (N=40) was carried out at a tertiary eye center in Hong Kong. The minimum follow-up period was 6 months. Criterion of success was reduction of IOP at least 30% or absolute IOP of 15 mmHg or below without (complete success) or with (qualified success) antiglaucomatous medication. Results. PhacoTbx had more reduction of antiglaucomatous medication (4 vs 1, P<0.001). At postoperative year one, there was more IOP reduction for phacoTbx than phacoECP (8 mmHg vs 3 mmHg, P=0.012). The one-year complete success rate was also higher for phacoTbx (46.2% vs 8.2%, P<0.001), while qualified success was comparable between the 2 groups (74.4% vs 73.5%, P=0.925). Operation time was shorter for phacoECP (37 vs 73 minutes, P<0.001). The number of postoperative follow-up visits was less (6 vs 11.5, P<0.001) for phacoECP. Additional surgical procedures were more common in phacoTbx (55% vs 0%, P<0.001). There was no postoperative cystoid macula edema, hypotony, or endophthalmitis reported in both groups. Conclusions. PhacoECP is significantly less effective than phacoTbx in reduction of both IOP and number of antiglaucomatous medications for patients with medically uncontrolled glaucoma and cataract. Its complete success rate is also significantly lower than that of phacoTbx. With its comparable qualified success, shorter operation time, less number of postoperative visits, and secondary surgical intervention, phacoECP may still have a role in very selected cases.

Implant System

To evaluate the implant and prosthetic of two implants with different surfaces and neck design. Enrolled patients received bone level, 12° conical connection implants (Nobel Parallel, Nobel Biocare; NOBEL group) with anodized surface (TiUnite) and roughness of 1.35 μm, or transmucosal implant system (Prama, Sweden and Martina; PRAMA group) with convergent collar, ZIrTi surface, and roughness 1.4–1.7 μm. Both implants were made of pure grade IV titanium, with similar diameter and length, chosen according to the dentistry department availability and patient’s request. After early prosthesis delivery, patients were filled for at least one year. Outcome measures were: implant and prosthetic survival and success rates, physiological marginal bone remodeling, periodontal parameters and pink esthetic score (PES). Results: Fifteen patients were allocated and treated in each group. At the one-year follow-up, three patients dropped out, one in the NOBEL group and two in the PRAMA group. During the entire time of investigation, all implants survived and the prostheses were successful. No statistically significant differences were found in term of marginal bone loss, periodontal parameters, and aesthetics (p > 0.05). Conclusion: With the limitations of the present study, both implant systems showed successful clinical results. Finally, many other clinical and surgical variables may influenced marginal bone levels, implant survival, and periodontal parameters. More homogenous clinical trials with larger samples are needed to confirm these preliminary conclusions.

<p style="text-align: justify;">Research in the conduct mode of grapevines other than the north African goblet incited us to make an investigation on the no bursting on table vine canes and to study if the vestigial dormancy is equivalent to acrotony phenomenon. Results of this survey clearly show that this phenomenon varies from one year to the other and that there is a negative interrelationship between the percentage of buds no bursted and the diameter of the basis of the cane on the one hand and of the top on the other hand. The difference in diameters of the basis and apical part is weakly correlated with the percentage of buds no bursted. As a result we concluded that at the level of the cane, the percentage of buds no bursted doesn't only depend on the diameter of the cane but also on the fixing of this one on the carrier axis. The bibliographic survey puts in exergue the low temperature role. We tried to dissociate the acrotony phenomenon and the vestigial dormancy. Test result show that the long cane fixing at the temperature of 4°C during 10 days removes partially or completely the vestigial dormancy but the phenomenon of the acrotony persists. We examined the qualitative answers of the investigation. In Tunisia, on long canes of Muscatel of Italy, a certain percentage of one year old presents both the acrotony (80 p. cent) and the basitony phenomena (8 p. cent) in 1995. The discussion of results of the investigation allowed us to give out a new hypothesis of work concerning the phenomenon which we will to verify.</p>

ABSTRACT Resorption is a pathologic process that always confuses the dentists with its varied etiologic factors and clinical presentations. Resorption can be classified into internal and external. Internal resorption lesions are notoriously difficult to manage because of their irregular and aberrant root canal anatomy. Immature apexes also possess a similar clinical challenge because of the absence of an apical stop. This article describes the nonsurgical management of a central incisor with severe internal resorption and an immature apex utilizing single-step mineral trioxide aggregate apexification along with injectable gutta-percha obturation.

AbstractConsiderable controversy surrounds the subject of tympanoplasty in children. This prospective study looked at the results of type-I tympanoplasty in children. Forty-five children in the age group of five to 14 years were selected for the study. All these cases had a central perforation without any evidence of cholesteatoma. The ear to be operated had to be dry for at least six weeks before surgery. Type I tympanoplasty was performed on these patients with autograft temporalis fascia by either the underlay or overlay technique.The overall success rates in 45 operations evaluated one year post-operatively was 91.1 per cent. The age of the patient had no influence on the success rate. The two factors which adversely influenced the success rate were the presence of near total perforation and bilateral perforations.It was concluded that type-I tympanoplasty has a good chance of success in children regardless of age.

Introduction Epistaxis is a common otorhinolaryngology emergency condition. Majority of it is anterior epistaxis which usually improves with conservative management. However, for posterior epistaxis, apart from posterior nasal packing, endoscopic sphenopalatine artery cauterization (ESPAC) is considered an effective measure for its control. Hence, this study was conducted to evaluate the outcome of endoscopic sphenopalatine artery cauterization for posterior epistaxis. MethodsRetrospective medical chart review of patients who underwent endoscopic sphenopalatine artery cauterization for posterior epistaxis from January to December 2018 at Ganesh Man Singh Memorial Academy of ENT-Head & Neck Surgery, Tribhuvan University Teaching Hospital, Kathmandu, Nepal. ResultsA total of 31 patients (21 males and 10 females) underwent ESPAC during the one-year period. Twenty-seven of them were unilateral whilst four were bilateral. Four of them rebled, of which two bled within 48 hours and the remaining two after two months. The overall success rate of ESPAC was 87.1% (27/31). ConclusionEndoscopic sphenopalatine artery cauterization is an effective measure to control posterior epistaxis.

Aim: aim of this study is to evaluate the clinical and radiographic healing after repairing mechanical furcal perforations that occurred in primary molars by using MTA (Mineral Trioxide Aggregate) and search in some factors that may affect the prognosis of the treatment. Materials & Methods: we had 34 primary molars in 32 children aged 5–10 years, were treated by using MTA material after the occurrence of furcal perforation during pulpotomy procedure. Cases had been followed clinically and radiographically within 12 months. Statistical analyses were performed at p-value = 0.05. Results: All teeth were asymptomatic at the first week. Overall success rate was 79.3%. There was no significant statistically differences between overall-success rates according to the perforation size and continues bleeding in the furcation area (p-value > 0.05). Conclusions: Iatrogenic furcal perforations that may occur during pulpotomy in primary molars can be treated successfully by using MTA, and small sized-perforations may have more favorable prognosis than the large ones.  Iatrogenic furcal perforations that may occur during pulpotomy in primary molars can be treated successfully by using MTA, and small sized- perforations may have more favorable prognosis than the large ones.
