Abstract The aim of this review is to discuss the digital planning and the use of guided technology in Endodontics. The complexity of the root canals anatomy and the challenges in the microorganism’s control represent risk factors for failure after the infected root canal’s treatment. Scientific improvements associated with technological advances have enabled better predictability of therapeutic procedures results. The development of efficient and modern devices provided safer root canal treatments, with shorter clinical visits and greater patient comfort. Digital endodontics incorporated different tools and developed its own, advancing even further in resolving complex cases. The faithful copy of the internal anatomy provided by the advancement of CBCT devices and software’s, associated with the digital resources of 3D planning and printing, enabled the advent of guided endodontics. This technique is used at different stages of endodontic treatment, with specific indications and greater result predictability. Therefore, this study critically reviewed the potential clinical application of this guided access technique, and the operative steps for its safe performance in managing complex endodontic cases. The main indications are accessing calcified root canals, performing endodontic surgeries in difficult access areas, removing fiberglass posts, and accessing teeth with developmental anomalies. In summary, guided endodontics has been a precise strategy, effective, safe, and clinically applicable. This procedure represents incorporating technological resources and digital planning in the Endodontist clinical practice, increasing predictability to complex cases.

Oedema and lymphoedema commonly occur in patients receiving palliative care. Community nurses frequently manage both in the home or must decide to refer for medical or specialist lymphoedema assessment. This article describes the types of oedema seen in palliative care and assists in clinical reasoning around the type of oedema presented and when to refer onwards. The treatments for palliative care oedema and lymphoedema are described, including how to adapt for complex cases and for patient comfort. Genital swelling, abdominal swelling, head and neck oedema and lymphorrhoea are also discussed.

The aim of this study was to describe a 16S rDNA-based nested polymerase chain reaction (nPCR) assay to investigate the occurrence of Campylobacter gracilis in oral infections. Samples were collected from ten infected root canals, ten cases of acute periradicular abscesses and eight cases of adult marginal periodontitis. DNA extracted from the samples was initially amplified using universal 16S rDNA primers. A second round of amplification used the first PCR products to detect C. gracilis using oligonucleotide primers designed from species-specific 16S rDNA signature sequences. The nPCR assay used in this study showed a detection limit of 10 C. gracilis cells and no cross-reactivity was observed with nontarget bacteria. C. gracilis was detected in the three types of oral infections investigated - 4/10 infected root canals; 2/10 acute periradicular abscesses; and 1/8 subgingival specimens from adult periodontitis. The method proposed in this study showed both high sensitivity and high specificity to directly detect C. gracilis in samples from root canal infections, abscesses, and subgingival plaque. Our findings confirmed that C. gracilis may be a member of the microbiota associated with distinct oral infections, and its specific role in such diseases requires further clarification.

The objective of this clinical study was to evaluate by polymerase chain reaction (PCR) the antimicrobial efficacy and the outcome of an endodontic protocol treatment (EPT) performed by under-graduated dental students on infected root canals associated with periapical lesions. Fifty-six patients attending for treatment of pulp necrosis and apical periodontitis were included. A specific EPT approach was performed and DNA extracts were taken at the baseline (S1), after a disinfection-neutralization procedure (S2), post-chemomechanical preparation (S3) and after Intracanal medication (S4) for the presence of specific bacteria. The outcome of the EPT was assessed radiographically using the Periapical Index-system (PAI) after 18-month follow-up. An intergroup evaluation shows that when comparing S1 to S3, S1 to S4, S2 to S3, and S2 to S4, the presence of bacteria were significantly reduced (P < 0.05). Finally, S4 was not significantly reduced when compared with S3 (P > 0.05). The most prevalent species in their respect order were Actinomyces Israelii > Enterococcus Faecalis > Fusobacterium Nucleatum/Prevotella Nigrescens > Phorphyromonas Endodontalis. After the 18-month follow-up, the overall success rate of root canal – treated teeth was of 88% (PAI 1 or 2). This In Vivo study demonstrated that EPT significantly reduced the number of cases with positive results for the studied bacteria, showing a profound positive impact in the outcome of endodontic treatment of teeth diagnosed with Pulp Necrosis and Apical Periodontitis.

Significant Difference

Aim: To determine and compare to what extent the intra-canal medicament like calcium hydroxide along with chemo-mechanical preparation reduces the bacterial load in infected root canals. Methodology: PubMed Cental, Medline, Google Scholar and hand search was carried out using the keywords calcium hydroxide (Ca(OH)2) , intra-canal medicament(ICM) and chemo-mechanical preparation. Selection Criteria: Clinical trials in which bacterial samples were evaluated at 3 intervals (Baseline, after chemo-mechanical preparation, after dressing with intra canal medicament ICM and trials which use Ca(OH)2 with any vehicle as ICM, but not compared with any other ICM were selected for this review. The data collection form was customized. The primary outcome measures were reduction of bacterial populations in infected root canals. Results: Seven clinical trials that met all inclusion criteria involving 117 participants were reviewed. Included studies showed significant difference in bacterial reduction after chemo-mechanical preparation and placement of Ca(OH)2 dressing for a week. In all included trials, Ca(OH)2 reduced bacterial load further compared with chemo-mechanical preparation. Conclusion: Ca(OH)2 as an inter-appointment medication promoted further decrease in the bacterial bioburden to levels significantly below those achieved by the chemo-mechanical procedures alone. Intra-canal medicament such as Ca(OH)2 should be considered for bacterial reduction along with chemo-mechanical preparation for long term success. Key Words: Intra-canal medicament, calcium hydroxide, Root canal treatment, bacterial load, Pulpitis
