The infraocclusion (IO) of primary molars, often seen in retained deciduous teeth, is a common condition that presents significant challenges for pediatric oral health. It occurs when primary molars are positioned below the occlusal plane due to the absence of permanent successors, leading to complications such as misaligned teeth, impaired chewing, and long-term dental health issues. Objectives: This study examines IO prevalence, diagnosis, and treatment approaches. Methods: A systematic review following PRISMA guidelines was conducted, searching PubMed, Web of Science, and Scopus for articles from the last 15 years. Nine articles were included for qualitative analysis. Results: IO was associated with several complications, including root resorption, altered eruption of adjacent teeth, and space loss within the dental arch. Clinical and radiographic evaluations are key to early detection. Severe cases often require invasive treatments, such as tooth extraction and space maintenance, while mild cases could be monitored. Conclusions: IO is prevalent in pediatric dentistry and can lead to significant dental issues if untreated. Early detection and intervention are crucial for preventing complications like tooth misalignment and impacted premolars. Tailored treatment strategies based on severity, along with increased awareness among dental practitioners, are essential to improve long-term outcomes for affected children.

Background: Permanently replacing missing teeth in the younger population is a clinical challenge. However, dental autotransplantation offers a viable treatment option in this demographic. To be performed predictably, it requires proper diagnoses, planning, and adherence to established guidelines in a multidisciplinary approach. Such guidelines should use evidence-based dentistry to anticipate and limit complications. The aim of this study is to evaluate the current literature on dental autotransplantation, discuss an evidence-based protocol, highlight steps for minimizing complications, and present a case report on two autotransplantations conducted at the Graduate Periodontology clinic at the University of North Carolina at Chapel Hill, Adams School of Dentistry, in the context of representative cases. Methods: A literature search using PubMed was conducted with the goal of constructing a comparative table on both survival and success rates of autotransplantation, providing a comparison of protocols and clinical studies and informing this narrative review. This review is illustrated by cases with the intention to highlight critical steps, limitations, and strengths of this mode of treatment. Results and Conclusions: Given the information presented, it is concluded that autotransplantation is a valuable treatment option provided established guidelines are followed. It is particularly useful for the younger population where implants or other options are not appropriate or feasible. This study also highlights some of the gaps in knowledge in autotransplantation which present opportunity for further studies to be developed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
