However, conventional systems, such as ProTaper Gold rotary file system, aim for complete debridement. In this meta-analysis, we aim to assess the efficacy of the TruNatomy and ProTaper Gold in reducing postoperative pain. In November 2025, we conducted a systematic search of PubMed, Scopus, Web of Science, and the Cochrane Library for randomized controlled trials (RCTs) comparing TruNatomy to ProTaper Gold in adult patients with pulpitis. For the meta-analysis, we used R 4.5.0 with R Studio 2024.12.1 + 563. Using a random-effects model, we evaluated dichotomous data using risk ratios (RRs) and 95% confidence intervals (95% CI); whereas continuous data were analyzed using standardized mean difference (SMD) and 95% CI. Visual inspection of the forest plot was used to determine statistical heterogeneity between trials, in addition to I-squared (I2) and chi-squared (Chi2) statistics.

This study investigated the antibacterial, antibiofilm, antioxidant, and anti-inflammatory activities of ethanolic extract of Z. mauritiana (ZM) leaves using both in vitro and in vivo models. The antibacterial activity of ZM extract was tested against Prevotella intermedia, Fusobacterium nucleatum, Streptococcus sanguinis, and Treponema denticola using the microdilution method to determine minimum inhibitory (MIC) and bactericidal (MBC) concentrations. Antibiofilm activity was assessed using a 96-well plate biofilm assay and confirmed by quantitative polymerase chain reaction (qPCR). Antioxidant activity was evaluated using the DPPH assay to determine the IC₅₀ value. For in vivo evaluation, gels containing 50% and 100% ZM extract were applied to tooth extraction sockets in Sprague-Dawley rats (n = 24).

Cone-beam computed tomography (CBCT) offers three-dimensional visualization, potentially enhancing diagnostic accuracy and prognostic evaluation. This systematic review and meta-analysis aimed to evaluate the role of CBCT in predicting the success of RCT by identifying anatomical and pathological factors that influence treatment outcomes. This review is the first to separately synthesize diagnostic accuracy and prognostic evidence for CBCT in predicting non-surgical RCT outcomes using subgroup analyses of voxel size and follow-up duration. Following PRISMA guidelines, electronic databases including PubMed, Scopus, Web of Science, and Embase were searched for relevant studies published between 2013 and 2024. Studies were categorized as (1) diagnostic accuracy studies or (2) prognostic studies assessing whether CBCT-identified variables predicted RCT success/failure. Data extraction and quality assessment were performed using appropriate critical appraisal tools. Meta-analysis was conducted to determine pooled effect sizes for periapical lesion detection, root fracture identification, and canal configuration assessment. Twelve studies (6 diagnostic accuracy; 6 prognostic outcome) involving various designs and sample sizes were included. Meta-analysis of diagnostic accuracy studies showed pooled sensitivity/specificity of 0.88/0.84 for periapical lesions (I² = 47%), 0.81/0.86 for vertical root fractures (I² = 52%), and 0.91/0.88 for canal morphology (I² = 28%). Prognostic meta-analysis demonstrated significant associations between CBCT-detected pathology and risk of post-treatment failure: periapical lesions (OR = 2.63; 95% CI 1.78-3.58; p < 0.001; I² = 39%), root fractures (OR = 3.48; 95% CI 2.05-5.12; p < 0.001; I² = 44%), and complex canal anatomy (OR = 1.94; 95% CI 1.20-2.82; p = 0.004; I² = 28%).

Branemark's old way of delaying loading has become trendier at present. Today, we have immediate and early protocols being widely used. These latest methods try to shorten treatment time while ensuring that osseointegration remains stable. As the surface technology of implants has become advanced and as digital planning and biomechanical understanding have improved so much, the older concepts of safe functional loading can be redefined. There is still clinical uncertainty about the long-term predictability of early load initiation for implants of varying quality and design. This review critically reviews recent (2019-2025) evidence into the biologic and biomechanical principles, clinical and decision-making principles for immediate, early, progressive and delayed loading of implants. The goal is to create an effective, evidence-based framework that practitioners can use for loading selection according to patient-specific factors, bone density and primary stability. To achieve the aim, a structured narrative review was conducted, which involved the databases including PubMed, Scopus, ScienceDirect and Wiley Online Library. The literature was searched using Boolean search strings that combined appropriate MeSH terms pertaining to 'dental implants', 'osseointegration', 'loading protocol' and 'primary stability'. Seventy-two studies (24 RCTs, 28 cohort studies and 20 systematic reviews/Meta-analysis) that met the inclusion criteria were qualitatively analyzed. When insertion torque was ≥ 35 N.cm, implant survival rates were between 95 and 100% in immediate and early loading protocols, comparable to that of delayed protocols. Similarly, for ISQ ≥ 70 and bone quality Type I-II. The difference in mean marginal bone loss between early and late loading was less than 0.2 mm at 12 months, which is clinically insignificant. Excess occlusal load, low bone density (type IV) and absence of prosthetic splinting were associated with failures. The implant bone interface in low-density bone improved as upgrades were made with progressive loaders. Implants in the lower jaw were more predictable than in the upper jaw. Immediate loading and early loading are both reliable if the biomechanical and biologic prerequisites are satisfied. This is a significant change from time-based loading to mechanically and biologically guided loading. Ways of working in the future will be AI-assisted torque analysis, digital bone-density mapping and biomimetic implant surfaces that enhance osseointegration under controlled functional load. Clinical Significance: Clinicians should determine the time of implant loading according to objective parameters rather than according to fixed timelines. Properly done immediate or early loading can shorten treatment time, improve patient satisfaction and provide long-term predictability comparable to those achieved with delayed approaches.</p>","PeriodicalId":47246,"journal":{"name":"Saudi Dental Journal","volume":"38 4","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13069059/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147655209","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}
