Periapical Status of Non-Root-Filled Teeth With Amalgam, Composite, or Crown Restorations: A Cross-Sectional Study.

抄録

目的:

OBJECTIVES: This study aimed to evaluate the periapical status (PAS) of restored non-root-filled (RNRF) teeth amongst a group of patients attending dental teaching clinics at Jordan University of Science & Technology. It also aimed to assess the association of type and quality of coronal restorations and periapical disease.

方法:

これは横断的研究である。参加者は、少なくとも1本の非根元充填歯に直接修復または間接修復を施していることが必要である。491人の参加者のサンプルを調査した。臨床検査とデジタル歯根膜X線写真を用いて、使用した材料を記録し、修復物の品質を評価した。PASと性別、年齢、修復物の材質・種類、品質との関連性を分析するために、カイ二乗検定とロジスティック回帰分析が用いられた。

METHODS: This was a cross-sectional study. To be included, participants needed to have at least 1 non-root-filled tooth restored with either direct or indirect restoration. A sample of 491 participants was examined. Clinical examination and digital periapical radiographs were used to record material used and assess the quality of the restorations. Chi-square test and logistic regression analysis were used to analyse the association between PAS and gender, age, restoration material/type, and quality.

結果:

全体の26.3%が1歯以上の歯根端部歯周炎（AP）と診断された．APの有病率は，アマルガム，コンポジット，インダイレクトの比較において，有意差は認められなかった（P=.386）．さらに，APと性別や年齢との関連は報告されなかったが，修復物の品質との有意な関連性が観察された（P < 0.001）．

RESULTS: Overall, 26.3% of the participants were diagnosed with apical periodontitis (AP) on 1 or more of the examined teeth. No significant differences in the prevalence of AP were observed when comparing amalgam to composite or indirect restorations (P = .386). Furthermore, no association was reported between AP and gender or age, while a significant association was observed with the restoration's quality (P < .001).

結論:

調査したサンプルにおけるAPの高い有病率は、臨床的な懸念であり、ヨルダンの歯の健康意識にもっと注意を向けるべきことを示唆している。不十分な修復物で修復された歯は，APを有する可能性が2倍高かった．

CONCLUSIONS: The high prevalence of AP in the examined sample is of clinical concern and suggests that more attention should be directed towards dental health awareness in Jordan. Teeth restored with inadequate restorations were twice as likely to have AP.
