Damascus University30 enrolled

Overview

Objective and background: The aim of this study is to evaluate the clinical outcome of using the hyaluronic acid gel in reconstructing inter-dental papillae at the aesthetic zones in a follow-up period of six months. Materials and Methods: 30 interdental papilla deficiencies which would meet the the inclusion criteria will be evaluated. After applying local anesthesia, 0.2 ml hyaluronic acid gel will be injected at the affected areas. This procedure will be repeated 3 times for the evaluated areas. Photographs will be taken before injection this material, and at 3 and 6 months following the intervention.

The presence or absence of the interproximal papilla is essential concern to periodontists, restorative dentists, and to the patients. The loss of papilla can cause cosmetic deformities (black triangles), phonetic problems, and food debris accumulation. Often the loss of papilla is a consequence of periodontal disease because of gingival inflammation, attachment loss and interproximal bone height resorption. Several reasons also lead to absence of interdental papillae including: 1\) Plaque associated lesions, 2) Traumatic oral hygiene procedures, 3) Abnormal tooth shape, 4) Improper contours of the restoration, 5) Spacing between teeth, 6) Loss of teeth.

Outcomes

Primary Outcomes

Percentage of change in papillary height (PCPH) from baseline measurement

The treated sites will be examined, defect measurements will be recorded, and photographs will be taken at a standard (1:1) magnification. The measurement of the distance from the tip of the interdental papilla to the base of the contact area for each study lesion separately using specific software.

Time frame: T0: baseline assessment, T1: immed. following injection, T2: after 3 weeks, T3: immed. following 2nd injection if required, T4: after 6 weeks from T1, T5: immed. following 3rd injection if needed, T6: after 3 months, T7: after 6 months postoperatively.

Secondary Outcomes

Change in the Interdental Papilla Index Score (CPIS) from baseline measurement

The treated sites will be examined clinically, using a periodontal probe
