目的:

歯髄炎患者の根管消毒において、次亜塩素酸ナトリウムとNd:YAGレーザーを併用した場合と次亜塩素酸ナトリウム単独の場合の臨床的治療効果を比較分析すること。

OBJECTIVE: To compare and analyze the clinical therapeutic effects of sodium hypochlorite combined with Nd: YAG laser and sodium hypochlorite alone for root canal disinfection in patients with pulpitis.

方法:

歯髄炎患者を乱数表法により対照群と観察群に分けた。両群とも根管治療を受け、対照群は1％次亜塩素酸ナトリウムによる根管灌流を受けた。観察群には1％次亜塩素酸ナトリウムとNd：YAGレーザーを併用した根管治療を行った。治療前と治療3ヵ月後の歯周病指数、炎症指数、LQスコア、細菌感染除去率を比較した。

METHODS: Patients with pulpitis were divided into control group and observation group according to random number table method. Both groups received root canal treatment, while the control group received root canal irrigation with 1% sodium hypochlorite. The observation group was irrigated with 1% sodium hypochlorite combined with Nd: YAG laser. Periodontal index, inflammatory index, life quality score and bacterial infection clearance rate of the two groups were compared before and 3 months after treatment.

結果:

観察群の総有効率は95.35％であり、対照群の79.07％より高かった（p<.05）。治療3ヵ月後、両群の歯周病指数と炎症レベルは低下し、観察群は対照群より低かった（p<.05）。また、観察群のLife Quality Scoreおよび感染除去率は対照群より有意に高かった（p<.05）。

RESULTS: The total effective rate of the observation group was 95.35%, which was higher than that of the control group 79.07% (p < .05). After 3 months of treatment, the periodontal index and inflammation level of both groups decreased, and the observation group was lower than that in the control group (p < .05). The life quality score and infection clearance rate of observation group were significantly higher than control group (p < .05).

結論:

1％次亜塩素酸ナトリウム単独による根管灌流と比較して、次亜塩素酸ナトリウムとNd：YAGレーザーを併用した根管消毒は、治療効果を有意に向上させ、炎症反応を緩和し、細菌感染を減少させることができる。

CONCLUSION: Compared with root canal irrigation with 1% sodium hypochlorite alone, sodium hypochlorite combined with Nd: YAG laser for root canal disinfection can significantly improve the therapeutic effect, relieve inflammatory reaction, and decrease bacterial infection.
