The aim of the clinical trial is to establish if one anaesthetic technique is superior in facilitating Endodontic treatment in Mandibular Premolar Teeth with SIP and to explore if a difference is observed when comparing anaesthesia of First and Second Premolars with use of MNB and IANB techniques. Patients were enroled as per strict inclusion and exclusion criteria, then attended for Endodontic treatment of a Mandibular Premolar Tooth with SIP. Local anaesthetic block technique was determined by random assignment to MNB or IANB. To ensure blinding of the operator with regards to the anaesthesia method, one clinician administered anaesthesia and placed dental dam, and a second clinician completed the procedure.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Case selection: &lt;/strong&gt;In total, 120 patients with a diagnosis of SIP of a Mandibular Premolar Tooth were enroled in the clinical trial. Inclusion criteria required participants be aged 18 to 65 years old and ASA Class I/II. Clinical signs indicative of SIP were required, including: carious pulpal exposure, haemorrhage during cavity preparation and prolonged pain in response to and persisting after thermal stimuli. Participants were excluded from the trial if they experienced pain involving multiple teeth or if there was use of pharmacological agents, with the ability to influence pain perception, within 6 hours of treatment. Participants were excluded from the trial if there was radiographic evidence of Periapical pathology, symptoms indicative of Apical Periodontitis or lack of anaesthesia 15 minutes after IANB administration. The sample size was determined using G*Power software and 60 patients were allocated to each group: MNB and IANB respectively. The drug preparation administered in all cases was 1.8 ml Articaine 4% with 1:100,000 epinephrine hydrochloride and the aspirating technique was used.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Data analysis: &lt;/strong&gt;Statistical analysis was completed using SPSS Statistics. Patients were verbally questioned prior to Endodontic treatment, with responses recorded on the Numerical Rating Scale (NRS).

The most common complications were gingival inflammation and caries. One abutment tooth was lost in the CRPD group versus none in the IARPD group. Peri-implant mucositis and peri-implantitis were observed in 42.9% and 10.7% of implants, respectively. Implant survival was 81.2%. Most MBL occurred prior to prosthetic loading, with minimal loss thereafter.</p><p><strong>Conclusions: </strong>Both CRPDs and IARPDs are viable treatment options for patients with Kennedy Class I edentulism, with no significant difference in the incidence of biologic complications between groups.</p>","PeriodicalId":12234,"journal":{"name":"Evidence-based dentistry","volume":" ","pages":"83-84"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12204855/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143960769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
