Aim: To compare the efficacy of depotphoresis and diode laser (DL) for reduction of microbial load and postoperative pain, and healing of periapical lesions in teeth with necrotic pulp. Methods: Ninety patients (98 roots) with pulp necrosis and chronic periapical lesions were randomized into three groups (n=30) of depotphoresis, diode laser, and control. Bacterial samples were collected from all roots at each treatment phase (S1: immediately after access cavity preparation, S2: immediately after cleaning and shaping, S3: one week after intracanal medicament). Analysis of bacterial reduction was performed using “Colony Forming Unit Counting” method. Level of pain was measured before and at 6, 12, 24, 48 and 72 hours after treatment using a visual analog scale (VAS). Cone-beam computed tomography (CBCT) images were obtained before and 6 months after treatment to assess the healing of periapical lesions based on their apicocoronal, mesiodistal and buccolingual diameter. Kruskal-Wallis and The Mann-Whitney test was used to determine the colony forming units and Compare the level of pain at different times between the groups of study, whilst the Univariate analyses using the chi-square or Fisher exact test were used to show the correlation of the outcomes with variables to identify the potential predisposing factors (P<0.05). Results: At S1, no significant difference was noted among the three groups in microbial load. At S2 and S3, there was a statistically significant lower bacterial count in DL (P=0.041) and depotphoresis group (P=0.001) respectively, compared to other groups. All patients had mild pain at all time points post-treatment. Also the size of the preoperative periapical lesions had no significant effect on the outcome of endodontic treatment (p>0.05). Conclusions: Root canal disinfection by depotphoresis and diode laser significantly decreased the microbial load as well as the post-endodontic pain and resulted in complete healing of some lesions in a short time.

The 37th National Congress of the Italian Society of Endodontics (SIE), that will take place in Bologna the next 12th and 13th of November, finally marks a new beginning of in-person activities, as symbolically represented by the motto “SIE restart”. Last year the absence of our National Congress was admirably replaced by the Virtual Endodontic Week Convention of SIE from 3rd to 7th of November 2020. However, the urgent need of social as well as scientific restart, in line with the improvement of the pandemic condition and in compliance with laws, has allowed the creation of a full cultural program that will deal with Endodontics: clinical protocols on scientific basis. Specifically, during the two-days Congress personalities of note belonging to our Society and scientific community will present several lectures to provide an excursus on different fields of endodontics, from traditional endodontic approach to endodontic surgery and minimally-invasive procedures, taking into account new digital technologies and supporting the clinical results with the most recent scientific evidences. Indeed, Evidenced-Based Medicine (EBM) plays a central role in daily clinical practice, allowing more expert clinicians to make more aware clinical decisions based on high quality scientific research with the aim to maintain the global health of patients. Even in the endodontic field, this approach not only provides more complete endodontists but also establishes the topics of future studies. Looking forward to see You in-person at the 37th National Congress of SIE!

Aim: This cross-sectional study aimed to assess the proximity of root apexes to the maxillary sinus and to verify the correlation between sinus mucosal thickening with the distance from the root apex to the sinus floor, endodontic treatment, age, tooth, sex, and presence of periapical lesion. Methodology: 169 cone-beam computed tomography images were selected, and 696 teeth were assessed, 600 without endodontic treatment, and 96 endodontically treated. The images were initially classified according to the study conducted by Kwak et al. (2004) to assess the proximity of the tooth roots to the maxillary sinus, and multiple logistic regression was subsequently applied to identify probable factors influencing the thickening of the sinus mucosa. Results: The vertical relationships between tooth roots and the sinus floor among the second premolars indicated a predominance of classification I (57.7%); whereas, in the first and second molars there was a predominance of types II (48.4%) and III (34.2%), respectively. The logistic regression did not indicate significant relationships between sinus mucosal thickening and the distance from the root apexes to the sinus floor, presence of endodontic treatment, and type of tooth (p>0.05). Age, presence of periapical lesions, and sex were associated with the presence of sinus thickening (p<0.05; odds ratio=1.03, 2.99, and 5.11, respectively). Conclusions: The presence of thickening in maxillary sinuses was correlated with the following factors: age, sex, and presence of periapical lesions.
目的:本横断面研究旨在评估根尖与上颌窦的接近程度，并验证窦黏膜增厚与根尖到窦底的距离、根管治疗、年龄、牙齿、性别和有无根尖周病变之间的关系。方法:选择169张锥形束ct图像，评估696颗牙齿，其中600颗未进行牙髓治疗，96颗进行了牙髓治疗。根据Kwak et al.(2004)的研究对图像进行初步分类，以评估牙根与上颌窦的接近程度，随后应用多元逻辑回归来确定影响上颌窦粘膜增厚的可能因素。结果:第二前磨牙牙根与窦底垂直关系以I型为主(57.7%);而在第一磨牙和第二磨牙中，II型和III型分别占48.4%和34.2%。logistic回归分析显示，鼻窦粘膜增厚与牙根尖到窦底的距离、是否接受根管治疗和牙型之间无显著关系(p>0.05)。年龄、有无根尖周病变、性别与鼻窦增厚相关(p<0.05;优势比分别为1.03、2.99和5.11)。结论:上颌窦增厚的存在与以下因素有关:年龄、性别和根尖周围病变的存在。

Aim: The present report describes the endodontic treatment of an immature maxillary central incisor with an open apex and extensive periapical lesion. Summary: Cone-beam computed tomographic images demonstrated the unusual root canal anatomy and a contemporary approach using bioceramic intracanal dressing, root repair materials and root canal sealers were used. One year after the end of treatment, the patient was asymptomatic and a new cone-beam computed tomographic exam showed complete apical repair, with new bone formation and closure of the root apex. The combination of modern imaging and the use of contemporary materials contributed to adequate diagnosis, planning and treatment of this case. Key-learning points: Immature permanent teeth with apical periodontitis represent a clinical challenge. Calcium silicate-based materials are widely used in endodontics, mainly due to their excellent biological and physical properties. The association of different type of calcium silicate-based materials could be a good option of the treatment of immature permanent teeth with apical periodontitis.

Aim: To describe the role of guided endodontics with ultrasonic tips in management of calcified canals. Summary Case 1: A 23-year old female presented with esthetic complaint related to the maxillary left central incisor with a history of trauma. Radiographic examination revealed internal resorption and apical calcification. A silicone impression of the maxillary jaw was obtained and scanned to plan for access of the calcified canal by means of implant planning software. Guides were fabricated through rapid prototyping and allowed for the correct orientation of an ultrasonic tip to provide access through the calcifications. An access cavity was done, the calcified canal was accessed by the help of the fabricated guide, and the root canal was prepared and obturated using warm vertical technique apical to the resorptive defect. The rest of the canal was filled with mineral trioxide aggregate (MTA). One-year follow-up revealed no symptoms and evidence of radiographic healing. Case 2: A 43-year old male was referred for endodontic treatment of the maxillary right first molar. The mesiobuccal and palatal canals were prepared by the referring dentist who failed to locate the distobuccal canal. Radiographic examination revealed a previously initiated root canal therapy, widening of the periodontal membrane space and coronal calcification of the distobuccal canal. A silicone impression of the maxillary jaw was obtained and scanned similar to the first case. The distobuccal canal was located using the ultrasonic tip through the guide, prepared, and obturated using warm vertical technique. One-year follow-up revealed no symptoms and evidence of radiographic healing. Key Learning Points Endodontics guides with ultrasonic tips are reliable in management of root canal calcifications. Three-dimensional imaging using CBCT and CAD/CAM provides accurate 3D guides.

Aim: To evaluate the effect of the position of fiber post placement on fracture resistance and location in endodontically treated teeth. Methodology: Forty healthy double-rooted human first premolars were divided into five groups. S: healthy teeth without intervention; C: endodontic treatment with MOD cavity preparation; CR: restoration with composite resin; CMP: fiber post placed horizontally in the center of the middle third of the crown; CAP: fiber post placed horizontally 2 mm below the center of the middle third of the crown. After thermocycling and fracture strength tests using a universal test machine, pulp floor involvement was evaluated. The Tukey test was used for statistical analysis. Results: Means and standard deviations of fracture strength (N) were as follow. S: 2451A±552.9; C: 32.63B±4.89; CR: 398.7C73.8; CRMFP: 1253D ±82.15; and CRAFP: 1156D±88.23 (different letters indicate statistical differences, P> 0.05). Posts placed 2 mm below the center of the middle third of the crown were associated with catastrophic fractures of the pulp chamber floor. Conclusions: The position of a fiber post seems to affect fracture location. The use of fiber posts, regardless of position, increases fracture resistance of endodontically treated teeth.

Aim: The objective of this study was to evaluate the amount of apically extruded debris and irrigants produced by TruNatomy and ProTaper Gold in mandibular incisor root canals. Methodology: Forty mandibular incisors were instrumented using TruNatomy (Dentsply Sirona, Maillefer, Ballaigues, Switzerland) and ProTaper Gold (Dentsply Sirona, Maillefer, Ballaigues, Switzerland) rotary systems. Apically extruded debris and irrigants during instrumentation were collected into preweighed Eppendorf tubes and were assessed with an electronic scale. All the procedures were performed in a 35 °C hot water bath. The data were analyzed using the Shapiro-Wilk test and Mann-Whitney U test at a 5% significance level. Results: Both NiTi file systems investigated extruded debris from the apical foramen. According to the data, the TruNatomy group extruded significantly less debris and irrigant from the apical foramen than the ProTaper Gold group (p<0.05). Conclusions: All the instruments caused apical extrusion. The TruNatomy instruments extruded less debris and irrigants apically than the ProTaper Gold instruments.

Aim: To investigate the marginal adaptation of Simvastatin (Smv), Mineral Trioxide Aggregate (MTA), and the combination of the two materials after direct pulp capping (DPC) in dogs’ teeth after three months. Methodology: DPC was performed at random on 18 maxillary and mandibular incisors of two dogs. The pulpal exposures in class V cavities were capped with either Smv or Smv+MTA or MTA. All cavities were restored with Intermediate Restorative Material (IRM). After a 90-day follow-up period, the dogs were euthanised and the incisors were sectioned into two halves and studied under the scanning electron microscope (SEM). The interface between the DPC materials and pulp as well as dentine is examined for gap mean percentage to the total area of the DPC material. Results: There was a statistically significant difference between Smv and Smv+MTA groups (P 0.05). The highest mean gap area percentage value was recorded in the Smv+MTA group (3.750±1.802) followed by the MTA group (2.121±1.166) while the lowest gap percentage was recorded in the Smv group (1.339±1.271). Conclusions: Simvastatin showed a good marginal adaptation property that encourages its use as DPC material.

The pulpal exposures in class V cavities were capped with either Smv or Smv+MTA or MTA. All cavities were restored with Intermediate Restorative Material (IRM). After a 90-day follow-up period, the dogs were euthanised and the incisors were sectioned into two halves and studied under the scanning electron microscope (SEM). The interface between the DPC materials and pulp as well as dentine is examined for gap mean percentage to the total area of the DPC material. \u0000Results: There was a statistically significant difference between Smv and Smv+MTA groups (P 0.05). The highest mean gap area percentage value was recorded in the Smv+MTA group (3.750±1.802) followed by the MTA group (2.121±1.166) while the lowest gap percentage was recorded in the Smv group (1.339±1.271). \u0000Conclusions: Simvastatin showed a good marginal adaptation property that encourages its use as DPC material.","PeriodicalId":42221,"journal":{"name":"Giornale Italiano di Endodonzia","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2021-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78850176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aim: To assess the bacterial leakage of two bioceramic sealers and compare them to an epoxy resin-based sealer. Methodology: A sample of 94 one-rooted premolars was obtained and separated into three experimental groups of 30 teeth; two samples were used for negative controls and two for positive controls. The experimental groups were obturated using the hydraulic compaction technique: Group 1, AH Plus® sealer, Group 2, Bioroot® RCS and Group 3, TotalFill® BC Sealer. The teeth were mounted on bacterial leakage devices and incubated at 37 °C for 30 days in a bilin esculin agar culture with Enterococcus Faecalis. Results: Leakage occurred in 27 roots (30%) of the entire sample. Group 1 (AH® Plus) showed the highest percentage of leaked samples (40%) and also took the least average days to leak (16,9) compared to Bioroot® (19,7) and TotalFill® (19,5), but the differences found were not significant (p>0,05). Conclusions: None of the sealers analyzed in this study produced an effective apical seal in which no bacterial leakage occurred. A third of the total sample presented leakage, but the differences between groups were not significant.
