# September 19, 2026 — Aesthetics & Dental category merge

The former skin, hair and body aesthetics group and dental and oral health group now share the navigation label **Aesthetics & Dental**. The library contains 28 active topics in five groups; the merged group contains eight topics.

The existing `aesthetics` group ID is retained. Dental alignment, regeneration and repair remains its own topic with the same `dental` topic ID, filename, evidence, scope and tags. Current indexes and topic navigation follow the merged group; older dental category links remain supported.

This is an organization-only change. Clinical content, historical records, topic research-check dates and the global research-run timestamp are unchanged.
