目的:
本研究では,原始歯列および混合歯列を有する若年小児患者の最大咬合力に及ぼす全口腔リハビリテーションの影響を分析することを目的とした.
Aim: The present study aimed at analysing the probable effects of full mouth oral rehabilitation on bite forces at their maximum extent in young paediatric patients with primary as well as mixed dentitions.
方法論:
本研究は他に類を見ないものであり,幼児の最大咬合力を調査した.平均年齢6.54歳の統計学的に有意な数の小児(=30名)を対象とした.約44.75%が男子,55.25%が女子であった.最大自発的咬合力は,治療直前と,必要な歯科治療終了後1ヶ月(3~5週間)の各参加者について評価した.歯科治療前後の咬合力の大きさの違いを統計的に分析した.さらに、年齢、身長、体重、BMI、性別、う蝕の重症度または歯の状態を含む主要変数と最大咬合力との相関関係を統計的に分析した。
Methodology: The present study is one of a kind and explores the maximum bite forces in young children. A statistically significant number of children ( = 30) with a mean age of 6.54 years. About 44.75% were boys and 55.25% were girls. The maximum voluntary bite force was assessed for each participant immediately before treatment and 1 month (3-5 weeks) following completion of the needful dental treatment. The difference in bite force magnitude before and after dental treatment was analysed statistically. In addition, the correlations of key variables including, age, height, weight, BMI, gender and caries severity or dental status with maximum bite force were statistically analysed.
結果:
治療前の全サンプル(=30)の平均最大咬合力は167.83 N(SD = 65.20)であった。男性サブグループの平均咬合力は175.39N(SD = 64.69)であったが、女性の平均咬合力は166.29N(SD = 68.93)であった。包括的な歯科治療の後、治療後の再診の予約に出席した子供たち(=30名)の平均最大咬合力は182.60N(SD=68.58)であった。
Results: The mean maximum bite force for the total sample ( = 30) prior to treatment was found to be 167.83 N (SD = 65.20). The mean bite force in the male subgroup was 175.39 N (SD = 64.69) while for the females the mean bite force was equal to 166.29 N (SD = 68.93). Following comprehensive dental treatment, the recorded mean maximum bite force for the children ( = 30) who attended the post-treatment review appointment was 182.60 N (SD = 68.58).
結論:
う蝕の程度、その重症度、臨床症状の有無などの本質的な要因は、最大咬合力に悪影響を及ぼします。
Conclusion: The essential factors such as the extent of dental caries, their severity, presence of clinical signs and symptoms has a negative impact on maximum bite force.
