序論:

永久歯が萌出している間の子供の歯肉溝の深さを測定することは、大人の基準値を基準にしている場合は特に困難である。

INTRODUCTION: Measuring the gingival sulcus depth in children while their permanent teeth erupt is rather difficult especially if using reference norms for adults for a base.

エイム:

健康な小児の永久歯萌出期における歯肉溝の深さの評価。

AIM: Assessment of the depth of the gingival sulcus during the period of tooth eruption in healthy children.

材料と方法:

この研究には30人の子供たちが含まれています（年齢範囲は6～14歳）。子供たちは口腔内の衛生状態が良好で、全身疾患の既往歴はありませんでした。臨床検査を行い、歯の状態、永久歯の萌出の段階（臨床冠の1/3まで、1/3から2/3まで、2/3以上、咬合接触）、歯肉溝の深さを電子プローブパロメーター（オレンジ）を使用して、遠近両耳、前庭、中近両耳、中舌、舌、遠舌の6部位で測定しました。その結果、最も高い値を持つものが溝の深さの最大値と考えられると結論づけられた。

MATERIALS AND METHODS: Thirty children were included in the study (age range 6 - 14 yrs). The children had good oral hygiene and no history of systemic disease. They were clinically examined - their dental statuses were taken, stages of permanent teeth eruption (up to 1/3 of the clinical crown, between 1/3 and 2/3, over 2/3, in occlusion contact), and their gingival sulcus depth was measured at 6 distovestibular, vestibular, mesiovestibular, mesiolingual, lingual, and distolingual sites using an electronic probe Parometer (Orange). It was concluded that the one with the highest value would be considered the maximum depth of the sulcus.

結果:

完全に萌出した歯の歯肉溝の深さは、健康な成人のそれと非常によく似ています（2.20～0.49mm）。また、切歯と犬歯の溝深さの変化は1.5mmの変動があり、発疹終了時には成人の溝深さに近い値を示しています。臼歯、小臼歯、切歯の溝の深さの最大値は遠位側で測定され、犬歯の溝の深さは中位側で測定されました。

RESULTS: The gingival sulcus depth in fully erupted teeth is very similar to that in healthy adults (2.20 - 0.49 mm). The change of sulcus depth in incisors and canines has a variation of 1.5 mm, which at the end of eruption is close to those in adults. Maximum sulcus depth for molars, premolars and incisors was measured distovestibularly, and for canines - mesiovestibularly.

結論:

歯肉溝の深さは、すべての歯の種類において、歯肉の発疹の様々な段階で減少し、発疹の終わりには、成人の基準に近い深さに達します。歯肉溝の深さに関して最も指標となるのは前庭探触点です。

CONCLUSION: At the various stages of eruption, the depth of the gingival sulcus plausibly decreases in all tooth types, and by the end of eruption it reaches a depth similar to that of the adult standard. Most indicative in regard to depth are the vestibular probing point.
