|Condition or disease||Intervention/treatment||Phase|
|Non-carious Cervical Lesions||Procedure: Relative isolation with cotton rolls Procedure: Absolute isolation with rubber dam||Phase 2 Phase 3|
|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||30 participants|
|Intervention Model:||Parallel Assignment|
|Masking:||Triple (Participant, Investigator, Outcomes Assessor)|
|Official Title:||Influence of Operatory Field Isolation Techniques on the Clinical Performance of Class V Restorations|
|Study Start Date :||July 2009|
|Primary Completion Date :||July 2011|
|Study Completion Date :||December 2011|
Active Comparator: Absolute isolation
Absolute isolation of the operatory field with rubber dam: Moisture control is provided by a rubber dam and a gingival retraction clamp placed in the cervical area of the tooth.
Procedure: Absolute isolation with rubber dam
Rubber dam group: Moisture control was provided by a rubber dam and a gingival retraction clamp placed in the cervical area of the tooth.
Experimental: Relative isolation
Relative isolation of the operatory field with cotton rolls: Moisture control was provided using a labial retractor, cotton rolls and gingival retraction cord placed into the gingival sulcus
Procedure: Relative isolation with cotton rolls
Cotton roll group: Moisture control was provided using a labial retractor, cotton rolls and gingival retraction cord placed into the gingival sulcus
- retention of restorations [ Time Frame: up to 72 months ]Retention of restorations is measured by clinical examination, where each placed restoration is checked and scored as present, partially lost or lost at the recalls.
- Restorations marginal staining [ Time Frame: up to 72 months ]Restorations are checked during recalls regarding the marginal staining and scored as clinically ideal, clinically acceptable; presence of small ditching; presence of extensive marginal ditching and need for repair /replacement.
- Periodontal condition of restored sites [ Time Frame: 6, 12, 24, 48 and 72 months after restorations' placement ]The periodontal condition of restored sites is evaluated based on the presence of supragingival plaque, gingival marginal bleeding, probing depth, and relative gingival recession.
