The focus question was, 'In a patient with a hopeless tooth that needs extraction with the indication for dental implant treatment, is immediate implant placement in damaged extraction sockets, compared to undamaged sockets or healed sites, an effective method for the replacement of hopeless teeth and achieving a favorable clinical result?' The risk of bias was appraised and a meta-analysis using random effect was applied.</p><p><strong>Results: </strong>Five studies with 135 patients and 138 implants were included. The implant survival rate was 100% for all studies and period evaluated; the pink esthetic score (PES) scores had no statistically significant result for all articles that evaluated this parameter; the soft tissue changes was reported by two studies: one found no significant differences and the other showed that the test group experienced reduced soft tissue loss at the 1-year evaluation (measured with digital intraoral scanners); another two studies assessed the marginal bone loss, presenting no differences between groups. The meta-analysis showed homogeneity between the studies. There was an equilibrium among the groups in the various studies included, and age tended to be lower in the test group.

It affects children and adults living in poverty, who have the most limited access to dental care. Left unexamined and untreated in the early stages, treatments for late-stage and severe caries are costly and unaffordable for socioeconomically disadvantaged families. If detected early, caries can be reversed to avoid more severe outcomes and a tremendous financial burden on the dental care system. Building upon a dataset of 50,179 intraoral tooth photos taken by various modalities, including smartphones and intraoral cameras, the present study developed a multi-stage deep learning-based pipeline of artificial intelligence algorithms that localize individual teeth and classify each tooth into several classes of caries. This study initially assigned International Caries Detection and Assessment System (ICDAS) scores to each tooth and subsequently grouped caries into two levels: level 1 for white spots (ICDAS 1 and 2) and level 2 for cavitated lesions (ICDAS 3 to 6). The system's performance was assessed across a broad spectrum of anterior and posterior teeth photographs. For anterior teeth, 89.78% sensitivity and 91.67% specificity for level 1 (white spots) and 97.06% sensitivity and 99.79% specificity for level 2 (cavitated lesions) were achieved, respectively. For the more challenging posterior teeth due to the higher variability in the location of white spots, 90.25% sensitivity and 86.96% specificity for level 1 and 95.8% sensitivity and 94.12% specificity for level 2 were achieved, respectively.
