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). \u0000Results: 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). \u0000Conclusions: 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.","PeriodicalId":42221,"journal":{"name":"Giornale Italiano di Endodonzia","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2021-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79218034","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}

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. \u0000Looking forward to see You in-person at the 37th National Congress of SIE!","PeriodicalId":42221,"journal":{"name":"Giornale Italiano di Endodonzia","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2021-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87816496","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}

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. \u0000Case 2: A 43-year old male was referred for endodontic treatment of the maxillary right first molar.
