Management strategies for unanticipated remnants following tooth extraction: A case report.
Article in Medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
rationaleTooth extraction is a common oral surgical procedure, yet rare complications such as retained tooth fragments may occur. These remnants - including crown fragments, root tips, or other materials - can delay healing, provoke infection, and impair oral function, posing challenges for clinicians. Because fragments may migrate extra-socket and be masked by fibrotic tissue, routine examination can be falsely negative and diagnosis delayed. This case report clarifies when and why early CBCT is warranted to localize retained crown fragments and demonstrates a micro-incision retrieval strategy that minimizes morbidity and supports timely recovery. PATIENT CONCERNS: A 27-year-old Chinese female presented with progressive buccal swelling and abnormal sensations 3 months after extraction of the mandibular right third molar (tooth 48). Cone-beam computed tomography (CBCT) identified 2 retained crown fragments. DIAGNOSES: Retained crown fragments were diagnosed on CBCT and correlated with the patient's symptoms.
interventionsThe fragments were surgically removed through a small distobuccal incision adjacent to tooth 47 under local anesthesia, after which symptoms resolved. OUTCOMES: Postoperative recovery was uneventful. The patient reported complete resolution of symptoms and improved oral function, with no complications during follow-up. LESSONS: This case highlights the potential for unanticipated remnants after tooth extraction and the need for prompt recognition. Early radiographic assessment - particularly CBCT when indicated - followed by timely surgical removal can prevent long-term complications and support optimal recovery.
