Occurrence of Third root (supernumerary/Radix Entomolaris/ Radix Paramolaris) in the Primary Mandibular Molars – A Systematic Review
Bibliographic record
Abstract
Purpose: The purpose of this systematic review is to evaluate the total prevalence of third roots seen in primary mandibular molars including both first and second in pediatric patients. Methods: An electronic search from three database was performed from inception till 2023 using different MeSH key words. Two independent authors carried out selection and analyses of the articles following PICO and PRISMA guidelines. To check the quality of included studies, modified New Ottawa scale was used. Results: Initial search following search of three electronic databases provided total 430 articles, in that only eight articles which fulfilled the inclusion criteria. The total prevalence of three rooted primary molars obtained ranged from 0.4% to 57% including only five different countries. There was no statistically significant difference found in gender wise comparison and also with right or left side occurrence. Its bilateral occurrence was shown only in two studies. Conclusion: There is insufficient data on overall prevalence of three rooted primary molars and also there are no quality studies undertaken across the globe. Future studies including more of cross-sectional and including advanced imaging techniques like CBCT is highly warranted in the arena of Paediatric Dentistry. This SR illuminate new pathways of knowledge about this root variation leading pediatric dentists to uncharted realms of understanding. Occurrence of lesion in Indian patient.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
