Abstract Background The present study aims to evaluate the effectiveness of mineral trioxide aggregate (MTA) application in treating dens evaginatus affected teeth with apical lesions and open apices using haemostatic collagen membrane to prevent the apical extrusion of MTA. Methods Twelve patients with 14 dens evaginatus affected teeth with apical lesions and open apices were treated with MTA apical plug and haemostatic collagen membrane. Clinical symptoms of subjective pain, pain of palpation, percussion, sinus tract, and the apical lesions' radiographic parameter were recorded at every 3-month interval up to 9 months after treatment. Paired t-test or Wilcoxon signed-rank test was used for statistical analysis with P < 0.05 as the threshold for considering results to be statistically significant. Results No patient experienced clinical symptoms 3 months after endodontic treatment. In addition, there was a significant difference in the dimensions of the apical lesions' before compared to 3 months after endodontic treatment. Conclusions The combination of MTA apical plug and haemostatic collagen membrane effectively treated dens evaginatus affected teeth with apical lesions, and open apices.

The Impact

IntroductionChronic exertional compartment syndrome (CECS) presents with pain during exercise, most commonly within the anterior compartment of the lower limb. A diagnosis is classically made from a typical history and the measurement of intramuscular compartmental pressure (IMCP) testing. Improved, more specific diagnostic criteria for IMCP testing allow clinicians to now be more certain of a diagnosis of CECS. Outcomes following surgical treatment in patients diagnosed using these more robust criteria are unknown.MethodsAll patients undergoing fasciectomy for anterior compartment CECS at a single rehabilitation unit were identified between 2014 and 2017. Wilcoxen signed-rank test was used to compare military fitness grading and paired t-test was used to compare Foot and Ankle Ability Measure, FAAM Sport Specific and Exercise-Induced LimbPain-G outcome measures, presurgery and postsurgery.ResultsThere was a significant difference in fitness grading between presurgical and postsurgical intervention (Z = −2.68, p < 0.01) with 46 % of patients improving their occupational medical grading. All secondary measures of outcome, looking at clinical symptoms, also improved.ConclusionAlmost half of the patients undergoing fasciectomy, following diagnosis using more specific criteria, will have an improvement in occupational medical grading. These outcomes represent the lower end of those reported in civilian populations. This is likely a result of a combination of factors, most notably the different diagnostic criteria followed and the more stringent criteria applied to military occupational grading, compared with civilian practice. Further work is now required to evaluate the impact of differing rehabilitation regimes on postoperative patients identified through this more specific diagnostic testing.

Objective: To evaluate the clinical and radiological outcome of MTA in nonvital teeth with open apices. Methods: Twenty-five non-vital teeth with open apices were treated with MTA apexification procedure. Standard endodontic procedures were followed and an apical plug of at least 5 mm was created by using MTA after a calcium hydroxide intra-canal dressing for at least 1 week. Final obturation was done after 24 hours by vertical compaction technique using gutta percha. Patients were recalled at 3, 6, 9 and 12 months interval. Clinical outcome was evaluated by assessing pain, tenderness, mobility and sinus tract. Blind to the treatment record, two examiners assessed the pre-treatment and post-treatment radiographs. Each radiograph was scored with the Periapical Index (PAI) and the size of the apical lesion was measured. The presence of an apical bridge over MTA was also noted. Results: Clinically 92% success rate was found whereas radiologically absolute success rate was 84%. Before treatment the mean PAI was 3.6 and mean size of the lesion was 3.24 mm. But, after 12 months follow up, the mean PAI was 1.36 and the mean lesion size was 0.68 mm. An apical barrier over MTA was distinguishable in 5 cases. Conclusion: Apexification using MTA can be considered as a predictable treatment option than calcium hydroxide apexification. DOI: http://dx.doi.org/10.3329/updcj.v3i2.17994 Update Dent.

Root Canals

The spread of root canal infection to surrounding periodontal tissue through accessory root canals reduces the success rate of endodontic treatment. In this case, cone-beam computed tomography revealed a lesion (4 mm from the apex) resulting from an accessory root canal of the maxillary left central incisor. First, non-surgical endodontic treatment was conducted but the sinus tract remained. Surgical preparation of the root cavity was then conducted to remove potentially infected dentin surrounding the accessory root canal. The cavity was filled and the foramen was sealed with resin containing bioactive surface pre-reacted glass (S-PRG) filler. The photopolymerized resin was then contoured and polished. In combination with subsequent supportive non-surgical endodontic treatment, a good clinical outcome with the disappearance of the sinus tract and clinical symptoms such as discomfort and pressure pain and the regeneration of the alveolar bone hanging over the cavity was obtained. In this case, the good clinical outcome may have been due to the dentin-adhesive property and durability of the pre-adhesive system and composite resin. The better biocompatibility of S-PRG fillers presumably facilitated periodontal tissue healing.

The biocompatibility of root canal filling material is one of the basic conditions for a successful endodontic treatment and healing of the periodontium. This study was aimed to evaluate the biocompatibility of calcium phosphate cement modified with the styrene-butadiene copolymer-modified calcium phosphate (mCPC) by its implantation in the subcutaneous tissue of rabbit. Fifteen female rabbits of comparable weight were used in this study, each one had received three different tubes; one containing mCPC, the other with mineral trioxide aggregate Fillapex, and an empty control tube on the subcutaneous tissue of thighs. After a definite time (3, 7, and 14 days), the tissues around the tubes were collected, fixed, and processed for histologic evaluation. A histopathological specialist measured the intensity of inflammation. Kruskal–Wallis test was used to analyze the data. The results showed a significant difference with mCPC group in different periods, there was a high intensity of inflammation at the beginning, then it fell, and sustained as mild inflammation. One can conclude that the new formulation of CPC considered biocompatible, which rises the success rate of endodontic treatment.

Summary Introduction Development of inflammatory lesions or their persistence after primary treatment is considered endodontic failure. The reason for failure can be complex anatomy of the canal system and numerous iatrogenic factors. The objective of this study was to analyze, clinically and radiographically, the causes of primary endodontic treatment failure and assess possibilities for retreatment of teeth with failed endodontic treatment. Method The study included 79 teeth (36 multirooted and 43 singlerooted tooth) indicated for repeated endodontic treatment. Based on the radiographic assessment of the status of periapical structures, teeth were divided into two groups. The first group included teeth without periapical lesions, i.e. the healthy periodontal tissues (PAI score of 1 and 2) in which retreatment was required for prosthodontic reason due to the poor quality of obturation (28 teeth), and the second group included teeth with visible signs of periapical tissue damage (PAI scores 3, 4 and 5) (51 teeth). In both groups, quality of obturation, coronal sealing and the presence or absence of clinical symptoms was analyzed. Results The most common radiographic finding of definitive obturation was short filling (65.8% of cases); “forgotten” canals (25.3%); non-homogeneous obturation with correct length (5.1%) and fractured instrument (3.8%). There was significant difference between healthy periodontal ligament and adequate restoration (P < 0.001). In 95% of patients with symptoms, changes in the periapical tissue were observed. Also, there was significant difference in the presence of symptoms after primary treatments, between the teeth with healthy apical periodontal tissue and teeth with periapical lesions (P = 0.019). Conclusion The outcome of the root canal treatment is significantly affected by the quality (density) of obturation and the presence and quality of coronal restoration. In patients with symptoms there were changes in the periapical tissue.

Pulmonary Malt Lymphoma

Background: We aimed to study the clinical features and survival outcomes of patients with early-stage primary pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma who underwent surgery.Methods: This is a retrospective, single-center study including 32 patients with early-stage primary pulmonary MALT lymphoma. Univariate and multivariate Cox analyses were performed to select independent prognostic factors. The overall survival (OS) was analyzed by the Kaplan-Meier method and was compared with the log-rank test.Results: Among the 32 patients included, there were 16 men (50.0%) and 16 women (50.0%). The average age was 59.2 years old. Ten patients had non-specific clinical symptoms including cough, expectoration, and chest pain, and four patients had B symptoms. CT images are not specific and can be shown as peripheral, central, solid, and ground glass but more peripheral (93.8%) and solid (75.0%). In prognostic analysis, univariate analysis showed that tumor stage and size were associated with relapse-free survival (RFS) and OS [hazard ratio (HR) = 1.105, 95% CI: 1.021–1.197, P = 0.011; HR = 1.211, 95% CI: 1.158–1.968, P = 0.003, respectively]. It seems to indicate that higher stage and larger size indicate a worse prognosis, but we could not find statistically significant predictors in multivariate analysis. Sublobectomy was performed in 21 (65.6) cases, lobectomy was performed in the other 11 (34.4) cases, both of them can achieve good prognosis (5-year RFS and OS are both 100%), and there is no significant difference between them.Conclusions: The clinical manifestation of early-stage primary pulmonary MALT lymphoma is not significantly specific, and surgical resection is an effective treatment.

ABSTRACT A significant problem associated with the endodontic treatment of necrotic teeth with open apices is achieving an acceptable seal in the apical area to allow compaction of root filling material. The procedure to create an apical barrier with a hard tissue at the root end is termed as Apexification. Calcium hydroxide is currently the most accepted material for the same. Because of the certain inadequacies associated with Calcium hydroxide Apexification, employing of an apical plug using MTA (Mineral Trioxide aggregate) has gained popularity in recent years. This article is thus an insight to the evolution and recent trends in Apexification.

Abstract Objectives Pancreatic cancers in most patients in Ecuador are diagnosed at an advanced stage of the disease, which is associated with lower survival. To determine the characteristics and global survival of pancreatic cancer patients in a social security hospital in Ecuador between 2007 and 2017. Methods A retrospective cohort study and a survival analysis were performed using all the available data in the electronic clinical records of patients with a diagnosis of pancreatic cancer in a Hospital of Specialties of Quito-Ecuador between 2007 and 2017. The included patients were those coded according to the ICD 10 between C25.0 and C25.9. Our univariate analysis calculated frequencies, measures of central tendency and dispersion. Through the Kaplan-Meier method we estimated the median time of survival and analyzed the difference in survival time among the different categories of our included variables. These differences were shown through the log rank test. Results A total of 357 patients diagnosed with pancreatic cancer between 2007 and 2017 were included in the study. More than two-thirds (69.9%) of the patients were diagnosed in late stages of the disease. The median survival time for all patients was of 4 months (P25: 2, P75: 8). Conclusions The statistically significant difference of survival time between types of treatment is the most relevant finding in this study, when comparing to all other types of treatments.
