The periodontal phenotype has been defined as the combination of gingival phenotype and buccal bone plate thickness (bone morphotype).Periodontal phenotype cannot be fully assessed but gingival phenotype can be evaluated through a standard and reproducible way. Gingival recession is usually observed in the presence of trauma and inflammation in individuals with thin phenotypes, whereas pocket formation has been reported in individuals with thick phenotypes. Various soft tissue augmentation procedures include: sub-epithelial connective tissue graft, free gingival graft, modified roll technique and use of acellular dermal matrix. The drawbacks of these techniques include second surgical site creation, post-operative discomfort, time consuming procedure, etc. Recent studies have shown i-PRF, microneedeling and hyaluronic acid procedures to be effective in increasing gingival tissue thickness. HA has been widely used in the dental field, specially periodontology, due to its bacteriostatic, fungistatic, anti-inflammatory, anti-edematous, osteoinductive, and pro-angiogenetic properties. HA's role in tissue regeneration and wound healing has gained huge interest in recent studies. Microneedling (MN) is also known as "percutaneous collagen induction therapy." Microinjuries created by MN result in minimal superficial bleedings and create a wound-healing cascade from which various growth factors, such as platelet-derived growth factors, transforming growth factors, connective tissue growth factor and fibroblast growth factors, are released.Study has shown a statistically significant increase in gingival thickness when microneedling was performed along with i-PRF in comparison to standalone i-PRF. Few human trials have been conducted using MN and Hyaluronic acids in literature for gingival augmentation in thin periodontal phenotype. Considering the effects of MN and hyaluronic acid on the biological potential, neoangiogenesis, neocollagenesis and wound, the present Randomized clinical trial is designed to evaluate the effects of MN alone and MN along with hyaluronic acid in thin gingival phenotype.

Gingival phenotype refers to gingival thickness (GT) and keratinized tissue width (KTW). Gingival phenotypes can be classified as scalloped and thin or flat and thick gingiva. Thin gingival phenotype are very friable and might be prone to recede in response to traumatic insults, such as plaque-related inflammation and traumatic toothbrushing .Studies have believed that HA accelerates the wound healing process, and promotes regeneration, as it maintains the viability of oral fibroblasts, increases their proliferative and migratory abilities, and enhances the expression of genes encoding type III collagen and transforming growth factor-β. Study has shown a statistically significant increase in gingival thickness when microneedling was performed along with i-PRF in comparison to standalone i-PRF. Given these characteristics,this study will be conducted to comparative evaluation of microneedling alone and along with hyaluronic acid on thin gingival phenotype. The present randomized controlled clinical trial will be conducted in the department of periodontics and oral implantology,Post Graduate Institute of Dental Sciences,Rohtak.Study design is of 24 months. Total 20 patients will be recruited on the basis of inclusion and exclusion criteria with thin periodontal phenotypes who had consulted to the Department of Periodontology, Post Graduate Institute of Dental Sciences, Rohtak. 20 systematically healthy patients having thin gingival phenotypes will be included in this split-mouth randomized controlled trial. For each patient, each side of the anterior mandible will be randomly allocated to one of the two procedures (MN or MN with Hyaluronic acid)using chit system. In the MN group microneedling will be done 1 mm below the gingival margin with 30-gauze lancet needles. In the HA with MN group, the selected sites of the gingiva will injected with cross-linked HA using a 30-gauge microneedle followed by microneedling. This described procedure will be repeated in both groups three times with intervals of 10 days. The GT, KTW, and periodontal indices: gingival index (GI), bleeding on probing (BOP), and probing depth (PD) will be measured at baseline, 1 month, 6 months and 9 months.
