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) — No general anaesthesia or deep sedation documented Oral sedation (awake and responsive) and IV 'deep conscious sedation'; FAQ: most patients remain responsive. No general anaesthesia is offered on the site. [rancho-san-diego-dental-group-sedation]

Change History
| Date | Change |
|---|---|
| 2026-10-16 | Re-read on 2026-10-16: the practice's website (all 93 sitemap pages: team, about, services, insurance and membership plan, appointment and location pages) and its Google listing. Recorded: digital 3D X-rays; online appointment requests with a preferred date and time, with out-of-pocket costs explained before treatment; Google 4.8 from 536 reviews, newest 2026-10-16, with owner replies. Corrected: prices — only membership-plan fees are published, not treatment prices; opening hours — weekdays until 4 or 5 PM and closed at weekends, so no evening or weekend hours; structured data — the markup names no dental practice with an address or phone. Still unverified: Facebook and TripAdvisor presence. Visibility re-checked on 2026-10-16 with the five canonical San Diego queries, read once for every clinic of the San Diego list; AI Overviews, local results and the first page of web results all counted. The clinic appears in 0 of the five. The query for an emergency dentist was read at night, and its earlier reading is kept for this clinic. |
| 2026-10-02 | Read the clinic's website HTML on 2026-10-02: structured data: present. |
| 2026-10-02 | Facebook presence changed to not established: no page of the practice is linked or confirmed; the empty Facebook link is removed (checked 2026-10-02). |
| 2026-10-02 | Read the clinic's Google listing on 2026-10-02 in 2 review orders (10 distinct reviews, dated 2020-08-20 to 2026-10-01; 4.8 from 530): recurring complaints false; suspicious review patterns false. |
| 2026-09-29 | Corrected 2026-09-29: review recency within 3 months (newest review dated 2026-09-25); owner replies to reviews confirmed on the Google listing (owner reply dated 2026-09-25). |
| 2026-08-25 | License verification 2026-08-25 against NPPES NPI Registry: clinic's own organizational NPI (1639275621, CA license 26243) found at its exact address. Of six named dentists, four matched CA license numbers (Jack Chan 48585, Thomas Brislin DS104296, Jeff Takai 59877 — Takai's registered address is San Francisco, not El Cajon); Nathan Christensen, Bryan Tran and Patricia Campillo were not confidently matched in NPPES. |
| 2026-08-25 | Recorded sedation / general anaesthesia availability (informational): not documented in public sources. Offers oral sedation ('awake and responsive') and IV sedation described as 'deep conscious sedation'; FAQ confirms patients 'remain responsive', not asleep. |
| 2026-08-25 | Re-verification 2026-08-25: confirmed website (ranchosandiegodental.com) live, address and phone unchanged, clinic operating (open). Google rating reconfirmed at 4.8; review count changed from stored 448 to 514; recorded Maps place URL and geo coordinates. Note: Google Maps lists the business as 'Rancho San Diego Dental' (without 'Group'); site branding/address/phone otherwise match, so name left as stored. |
