SUMMARY

Purpose: The study aimed to examine the effects

of relay often with pool water is treated with chloride

to the status of ivory tooth erosion and sensitivity.

Aim: Survey abrasive conditions on intensive class

student group swim University Sport from Son - Bac

Ninh in 2013, Survey dentin hypersensitivity in the

student group. Methods: cross-sectional descriptive

study on 56 students >18 years University Sport Tu

Son, Bac Ninh, were randomly selected from a total

of 90 advanced students of the school swimming.

Damage to tooth erosion are examined and evaluated

based on TWI index of B.G.N Smith and J.K Knight

(1984). Schiff test used to assess the sensitivity of

ivory. Results: Prevalence of dental erosion

accounted for 96.43 % is high: worn at the neck

position that occupies 68.98 %, 16.54 % occupied

chewing surface, the outer surface occupied 14.24 %,

accounting for 0.25 % of the surface, tooth erosion

accounted for 97.71 % level 1, level 2 accounted for

2.29 %. The rate is quite high sensitive dentin

occupies 17.86 %: sensitivity to cold stimuli 50.94 %,

30.19 % stimulation sour, sweet stimulus 7.55 %,

11.32 % other stimuli.Conclusion: The rate of tooth

wear and sensitivity of students ivory swimming at a

high level (96.43 % has worn teeth, sensitive dentin

17.86 %), the relay pool with water treated by chlorine

in the long run without protective measures may be

the major risk factors for dental erosion and dentin

sensitivity.

Keywords: Chloride and worn teeth; pool water

Sensitive ivory.
