Research objectives and plan
Restore natural tooth substance and form, gums, living attachment, sensation and stable position after temporary support; pursue durable youthful function throughout the body.
These are research objectives. Photos constrain visible form but do not uniquely recover hidden tooth thickness or internal damage.
Illustrative model
Executed 30 support/contact cases with force, moment and energy checks. Equal support-length loss gives different compliance; two manufactured support distributions share the whole global stiffness matrix while local forces differ.
Every length, stiffness and load is illustrative. The rigid crown does not model restored enamel thickness, biological healing, human mobility thresholds or stable position after support withdrawal.
Published data reanalysis
For two reported buccal cell-line model conditions, thickness differs 7.543-fold, electrical resistance-area product 1.016-fold and standard FD20 apparent permeability 0.577-fold.
These are aggregate summaries with reported SEM and replicate counts, not paired donor/insert effects. Commercial total thickness includes matrix. The narrowed noninfectious comparison does not establish native gingival restoration.
Source audit with conditional calculations
Compared six printed mouse-study associations: 1-hour and 24-hour qPCR each against a fixed 24-hour reporter. Display-rounded differences stay positive; late organ accumulation can disagree with reporter location.
No new fit, raw paired animal series, intended-cell fraction or repair outcome is supplied. Reporter area retains prior activity, and three image fields do not establish three independent animals. Rounding bounds are not confidence intervals.
Observational data reanalysis
Linked all five patients in a human pulp pilot. At 24 weeks, four had positive electric sensibility; three also had unambiguously absent periapical radiolucency. An adverse radiograph coexists with positive sensibility in another patient.
This is an uncontrolled five-patient measured pattern, not a regeneration success rate. MRI signal is not blood flow, late responses stay at their later visit, and CBCT timing/unit conflicts remain unresolved.
Published data reanalysis
Recomputed 200 deposited OCT positions after thermal cycling. Conditional block summaries reproduce all four published SDs; descriptive CHX contrasts point in opposite directions across adhesive modes.
Source blocks lack tooth IDs. OCT enhanced-signal width is a proxy, thermal cycling is distinct from mechanical fatigue, and separate tensile records cannot be joined to nominal repair depth.
Observational data reanalysis
Reconstructed six reported clinical-summary groups, four descriptive contrasts and the short follow-up timeline from the original single-patient CPS1 base-editing report.
One infant, unequal sampling windows, unknown specimen counts and continuing care prevent an isolated causal effect. Liver biopsy was deferred; corrected-cell fractions and any ordinary-aging coverage threshold remain unknown.
Published data reanalysis
Reanalyzed 14 listed crack-resistance curves, three contact-fatigue traces and three brushing-roughness summary pairs from the HEA workbook. Roughness worsens in all three material summaries.
Listed traces and serial points do not identify independent specimens. Bulk response and the separate delamination traces do not link actual repair thickness to host-interface fatigue or clinical durability.
Published data reanalysis
Recomputed 777 micrometers of construct shortening and all six native-human tensile summary rows. Native summary moduli change across coupled force and loading-rate regimes.
Force and shortening in the construct are algebraically linked. Active contraction and passive modulus cannot establish equivalent tissue function, donor-age effects, regenerated bilateral attachment or stable tooth position.
Source audit with conditional calculations
Qualified a primary ELISA/LC-MS disagreement and the K14Q steady-state comparison, preserving its variant-specific plasma calibration. None of the four bounded source contexts qualifies as administered-parent concentration-time PK.
Signal-to-detection-limit scale separation is not true concentration or universal assay failure. One steady-state immunoreactive measurement does not identify intact-parent half-life or oral availability; donor-linked repair data remain unavailable.
Published data reanalysis
Analyzed 384 optical-margin rows and 48 fracture records. Thirty-seven teeth have internally consistent links; adverse joint-outcome bounds retain all 48.
Eleven teeth have identity uncertainty. Deposited low load and blank margin fields stay unchanged. Preparation depth is nominal; these are extracted restored teeth, not regenerated tissue.
Observational data reanalysis
The full-cohort conflict spans nearly every fixed ECM gene. Restricting the bulk cohort to younger ages reverses its direction; shared-decade analysis preserves the earlier opposition.
The common-span restriction removes every bulk donor over 45. These subsets are not matched-age or matched-donor validation, and expression is not restored function.
Published data reanalysis
Original paired data reproduce DL001 selectivity: 433.38 as the mean of paired ratios, versus 350.24 as the ratio of means. The apparent discrepancy is resolved.
Different assay states, unequal tissue responses and unmatched blood contexts remain. There is no direct DL001 reproductive-protection comparison or established healthy-human testicular-volume inference.
Published data reanalysis
Recomputed 75 stored source positions. Apparent toughness improves over acid-etched enamel but remains below the native mean; enamel wear directions are unfavorable.
Source positions are not independent donors. Actual repair-depth and interface measurements are not linked to these specimen outcomes.
Analysis software with synthetic examples
The analysis preserves specimen/tooth/donor nesting, missing leakage and censored fatigue outcomes. The linked examples are synthetic.
The real 75-position source extract supplies zero identifiable linked specimens. Software examples are not regenerated tissue or material performance measurements.
Observational data reanalysis
Structural-ECM age slopes stay positive in observed and common-RNA partial mixtures, opposing the earlier bulk-tissue direction.
The retained groups cover 99.55% of captured cells, but omitted RNA is unknown. This is not reconstructed whole tissue or a biological-age clock.
Source audit with conditional calculations
Separated intact parent from metabolites, reproduced 21 cellular summaries and bounded oral material needs without assigning oral availability.
Useful cellular access, oral availability and actual manufacturing cost remain unknown. Repeated source values across endpoints are retained as unresolved dependence.
Illustrative model
A reversible, finite-capacity model uses published buffer affinities to test capture and competition; equimolar host does not imply complete capture.
Chosen buffer concentrations are not human exposures or doses. Paraxanthine capture, oral delivery, brain exchange and sleep recovery are unresolved.
Published data reanalysis
Reconstructed 48 paired insulin observations. The flow/vascular-bed condition has the highest mean relative stimulation index, but not the highest absolute stimulated output.
These are source cell-line spheroids, not patient grafts. Donor, lot and circuit crosswalks are unavailable; the pairs cannot be counted as independent people.
Illustrative model
The joint-endpoint audit shows why separate favorable measurements cannot establish how many units satisfy every required repair condition.
The illustrative endpoint counts are synthetic. Allele, cell and tissue-area denominators cannot be silently combined.
