目的:评估两种正畸矫治器正畸治疗上颌前牵引手术修复唇腭裂(CLP)患者口腔健康状况和龈下菌斑菌群。
方法:随机对照试验。
方法:机构。
方法:共90例经手术修复的单侧唇腭裂患者,在最初招募的120名患者中,分为3组:实验组I,实验组II和对照组,每人30个科目。在过去6个月内有口服预防史或在3个月内有抗生素治疗史的患者被排除在研究之外。
方法:实验Ⅰ组进行骨固定上颌前突,实验组II采用带丙烯酸咬合板的面罩进行上颌前牵引,对照组不进行正畸干预。
方法:斑块指数(PI),牙龈指数(GI),牙龈出血指数(GBI),探测深度(PD),和龈下菌斑的微生物群(P.牙龈,P.中间媒体,Veillonella和Capnocytophaga)在基线(T0)和8个月(T1)后进行比较。
结果:PI,GI,在8个月的间隔内,实验组II和实验组I的GBI和PD明显高于对照组(P<.001)。实验组II和实验组I的微生物数量显著增加(P<0.001),与对照组相比。
结论:发现带面罩和骨板的上颌前牵引比带咬合板的面罩更好。考虑CLP患者的整体口腔健康。
OBJECTIVE: To assess the oral health status and microbiota of subgingival plaque in patients with surgically repaired cleft lip and palate (CLP) during orthodontic treatment for maxillary protraction with two different orthodontic appliances.
METHODS: Randomized controlled trial.
METHODS: Institutional.
METHODS: A total of 90 patients with surgically repaired Unilateral Cleft Lip and Palate, out of initially enrolled 120 patients, were divided into 3 groups: experimental group I, experimental group II and control group, with 30 subjects each. Patients with a history of oral prophylaxis in last 6 months or antibiotic therapy within 3 months were excluded from the study.
METHODS: Bone Anchored Maxillary Protraction was done in experimental group I, while facemask with acrylic occlusal splint was used for maxillary protraction in experimental group II and no orthodontic intervention in control group.
METHODS: Plaque Index (PI), Gingival Index (GI), Gingival Bleeding Index (GBI), Probing Depth (PD), and microbiota of subgingival plaque (P. gingivalis, P. intermedia, Veillonella and Capnocytophaga) were compared at baseline (T0) and after 8 months (T1).
RESULTS: The PI, GI, GBI and PD were observed to be significantly higher in experimental group II followed by experimental group I as compared to control group at 8 months interval (P < .001). The microbiota counts increased significantly in experimental group II and experimental group I (P < .001), as compared to control group.
CONCLUSIONS: Maxillary protraction with facemask and bone plates was found to be a better alternative than facemask with occlusal splint, considering the overall oral health of patients with CLP.
