<think> The user wants a brand story in Chinese for Oral-B, more than 200 characters (or Chinese characters?). The requirement: 200 words? It says 200字以上 - presumably Chinese characters count, so at least 200 characters. Should be based on real history: Oral-B founded in 1950, by a periodontist? Actually Oral-B started as a small dental product company called "Oral B Laboratories" in California? Let''s recall correct history: Oral-B is a brand of oral care products owned by Procter & Gamble. It originated from the "Oral-B" brand that was started by a dentist named Dr. Robert W. G. in the 1950s? Wait need accurate timeline. Let''s dig into the known history: - The brand was founded by Dr. Robert W. G. ??? Actually, "Oral-B" brand was created by a periodontist named Dr. John J. O''Leary? I''m not sure. Let''s research mental memory: Oral-B''s founder was Dr. Robert A. Gill? Hmm. I recall that Oral-B''s first product was a "sensitive toothbrush" in 1950, and the "Oral-B" name stands for "oral hygiene"? The company''s origins: In 1950, Dr. John C. Baker? I need to recall precisely. Let''s check known facts: Oral-B brand originally belonged to "Oral-B Laboratories" founded in 1950 by Dr. James B. Haskin? Wait, I think the founder was Dr. Robert H. Grable? Hmm. Better to check memory: The Oral-B brand started in 1950 when a dentist named Dr. Robert J. O''Neil? Not sure. Actually I think it''s correct that "Oral-B" was founded by the dentist Dr. John H. O''Connell? Or Dr. Gerald H. K.? Let''s step back. I know Procter & Gamble acquired Oral-B brand in 2005 from Gillette? Actually P&G had brand rights earlier. Oral-B was originally a product line from the "Oral-B" company which was founded by Dr. John J. O. "Dr. J. G." Something like that. Let''s think: The "Oral-B" name came from "Oral B" stands for "Oral B" - like B? But I recall that the name derived from "Oral B" as a brand by a periodontist named Dr. Robert W. "Bobby" ... hmm. Better to search: Actually the founder of Oral-B is Dr. John H. L. "John J." He was a periodontist. In 1950, he started to develop a toothbrush with a "B" shaped head, making it easier to clean back teeth. He called it "Oral B" because of the B-shaped head. The company grew from there, later introduced the "Oral-B CrossAction" brush, then iO series, etc. Alternatively, maybe </think>
