General Anaesthesia & Deep Sedation
Whether the clinic documents treatment under general anaesthesia or deep / twilight sedation — "sleep dentistry", where the patient is asleep and unaware (does not feel, see, or hear the procedure). Ordinary conscious sedation, where the patient stays awake and responsive, does not count here. This is informational and does not affect the transparency score.
- ? General anaesthesia / deep sedation (sleep dentistry) — Not verified No anaesthesia/sedation information found on current practice site; academic implant-surgery literature by Dr. Dada references GA/MEOPA generally but not confirmed as offered by his own clinic

Change History
| Date | Change |
|---|---|
| 2026-08-25 | License verification 2026-08-25 against ONCD annuaire: both named doctors (Karim Dada, Dorothee Louis-Olszewski) found with matching RPPS numbers, corroborated by older-format Ordre numbers published on the clinic's own mentions-legales page; registry still shows their former Tour-Maubourg address rather than the current Rue Guy de Maupassant location. FINESS not applicable (liberal cabinet, not a centre de sante); clinic's own site shows only a commercial SIRET/RCS. |
| 2026-08-25 | Re-verification 2026-08-25: the original '62LTM' listing at the on-file address (Boulevard de la Tour-Maubourg, 75007 Paris, same phone) shows 'Permanently closed' on Google Maps. Dr. Karim Dada now practices at a new address, 8 Rue Guy de Maupassant, 75116 Paris, with a new practice website (dr-dada-karim.chirurgiens-dentistes.fr); phone unchanged (+33 1 42 88 40 81); the original leadingimplantcenters.com profile page is still live as a bio/profile page. Updated address and website fields to the new location. Captured Google rating 5.0 (70 reviews), geo coordinates and Maps URL at the new address. Sedation research: no anaesthesia/sedation information found on the current practice site (academic publications by Dr. Dada reference general anaesthesia/MEOPA sedation in implant-surgery literature generally, but this was not confirmed as offered directly by his own clinic, so left unset). |
