A GRAPHIC TOOL TO HELP CONSUMERS

DETERMINE WHEN TO REPLACE

A TOOTHBRUSH: A COHORT STUDY

INTERNATIONAL DENTAL JOURNAL

2012; 62: 154–160

폴리클 2조 35번 양지선

연구 동기대부분의나라가

칫솔교체시기로 3개월을권장.

Ex)프랑스경우 1일 3번칫솔질을하면

3개월마다교체권장

But…

가이드라인발표시기.

칫솔강모가단단하나부드럽나

치면에닿는강모의형태-치태제거부위다양

같은칫솔이라도강모길이가다양

사용자의칫솔질회수, 습관, 압력정도, 칫솔질시간

→칫솔교체를위한 3개월권장사항이얼마나실효

성이있으며요즘현대인에게도적용될수있는가?

OBJECTIVES:

Q. 칫솔의교체시기는?

→The aim of this study was to create and validate a drawing to help adults establish when to replace a manual toothbrush.

성인의칫솔교체시기에대한개념을확립하기위한시각적자료제시

Methods

임상평가

• 구강위생지수 Turesky- Gilmore-Glickman modification of

Quigley Hein plaque index

칫솔 평가

• Wear index 이용

임상평가- TURESKY MODIFICATION

OF THE

QUIGLEY HEIN INDEX

O Plaque discoloration

0=No plaque

1=Slight flecks at the cervical margin

2=thin continuous band (≤1 mm) at

cervical margin

3＝A band of plaque >1 mm but < 1/3 of

the area

4＝covering 1/3 2/3 of the area

5＝covering ≥ 2/3 of the area

They examined only d facial surfaces of tooth using fuchsin

mouthwash. D index emphasis on plaque accumulation in

gingival third of tooth.

구강위생상태 평가할때사용 (ex. 칫솔질의청결효과평가)

모든치아의협(순)면과설면검사 (제 3대구치제외)

착색후염색된상태로평가

지수의계산

QH index = 총점수의합/ 검사한총치면수

칫솔 평가-WEAR INDEX

Spreading and

bending(flexibility) of tooth

brush bristles

WI 68% 이상이되면치태제거능력이현저히떨어진다고입증됨

Worn 칫솔을mm자와함께석고에고정시킨뒤, 실험자의칫솔은모두동일한거리에서카메라를사용하여 spreading을측정.

METHODS

Phase I was to determine the wear after use of a tested

toothbrush (Soft Elmex; Gaba Laboratoire, Paris, France)-3개월간 50명

Phase II was to validate the wear drawing generated in Phase

I among other users.-Phase I을확인하기위해 3개월간 30명

실험칫솔사용후WI(마모도지수) 조사.

단계1에서얻어진마모그림을입증하기위해

단계2 진행.

대상 조건

① 18세이상

② 25개이상의자연치존재

③ 교합면우식이없어야함

④ 12. 31. 16, 26, 36, 46 검사치아에우식이없어야함

⑤ 교정치료, 가공의치, 치주염있는경우제외

*임상실험은실험자에게자신의칫솔이마모되었다고생각했을때반납하며최대 3개월안에반납을요구. 동일한 검사자가실험자의칫솔질에대한문진을했으며, TQHPI를측정하였음. 일관성측정에서 0.80기록함. 협면 12, 31, 46, 26/ 설면 16, 36

*Phase 1. 여 42명, 남 18명. 18세~57세.

(43명칫솔, 6명자동칫솔, 1명복합)

*Phase 2. 30명

RESULTS

Phase 1 Phase2

횟수 2.1회 (1~3회)

칫솔질시간 118.6초 (52초~258초)

교체시기 38.6일 (15일~65일) 34.2일 (15~45일)

WI 88.7% (6~169%) 81.4 (36~147%)

Pink-새칫솔

Blue~Green마모도, Purple 평균, Turquoise 마지노선WI 68%

CONCLUSIONS:

This simple drawing may help adults establish

when they should replace a toothbrush.

간단한시각적자료가성인들이칫솔을교체할시기를인식하는데도움을준다.

DISCUSSION

1. 가이드라인보다더객관적이다

-칫솔디자인, 재료, 실험자습관(칫솔법, 압력), 해부학적다양성

2. 단칫솔질시간은 45초~60초로일관적이다.

-칫솔마모도와상관없이

3. Laboratory worn toothbrush가아니라 natural worn

- 다양성반영

4. 치아의모양에대한고찰

-가장긴길이의강모. 치면의불규칙한마모, 오른손잡이

-왼손잡이사람에게도적합한그림이필요
