Conditions
Detailed Description
AIM: To evaluate and compare the clinical, esthetic and patient-related outcomes of gingival depigmentation performed via Microsurgery vs Diode Laser technique.
OBJECTIVES:
To evaluate and compare melanin pigmentation using Dummett Oral Pigmentation Index (DOPI), Hedin melanin index (HMI) between both the treatment modalities at baseline, 1 week, 1 month and 3 months post-operatively.
To assess a) patient-related outcome measures (PROMs) such as post-operative pain perception/discomfort on a visual analog scale (VAS) , patient's preference of the mode of treatment /esthetic satisfaction and b) clinical parameters13 such as bleeding, redness, swelling, wound healing, gingival colour, gingival morphology at baseline, within 24 hours, 1 week, 1 month and 3 months.
To evaluate the effect of different treatment modalities on melanocyte histopathologic count (MHC).
SETTING: Department of Periodontology and Oral Implantology, PGIDS, Rohtak, Haryana.
STUDY DESIGN: Split-mouth Comparative Randomised Controlled Clinical Study. TIME FRAME: 3 months SAMPLE SIZE: To achieve a power of 80%, level of significance of 5% and assuming an effect size of 0.8, a minimum sample size of 18 patients is needed in each group. Accounting for a 20% drop out rate, 22 patients are needed in each group.
METHODOLOGY: Patients with a chief complaint of unpleasant appearance of gingival tissue will be recruited from the outpatient Department of Periodontology, PGIDS, Rohtak. Patients fulfilling the eligibility criteria will be enrolled in the study after obtaining an informed written consent. A split-mouth design with maxillary and mandibular anteriors being randomly allocated into test (Microsurgery) and control (Diode laser technique) group to each patient using a chit method.
STATISTICAL ANALYSIS: Data recorded will be processed by standard statistical analysis. The normality of distribution of data will be examined by Shapiro Wilk test. Statistical analysis will be performed according to distribution of data. If it is in normal distribution, intra group comparison will be done by paired t-test between two time points and inter group comparison will be done by using unpaired t-test between two groups. If it is in non-normal distribution, intra group comparison will be done by Wilcoxon signed rank test and inter group comparison will be done by Mann-Whitney U test.

The probing depth measurements will be assessed using a calibrated manual periodontal probe (PCP-UNC 15 Hu-Friedy, Chicago, IL, USA). The probe will be inserted with a firm, gentle pressure to the bottom of the pocket and maintained parallel to the vertical axis of the tooth. Measurements will be noted at 6 sites of each tooth - mesio-buccal, mid-buccal, disto-buccal, mesio-lingual, mid-lingual and disto-lingual. Measurements will be rounded to the nearest whole millimetre. |

CLINICAL ATTACHMENT LEVEL (CAL) Clinical Attachment Level will be measured as the distance between the base of the pocket and the cemento-enamel junction (CEJ). Measurements will be made at 6 sites of each tooth- mesio-buccal, mid-buccal, disto-buccal, mesio-lingual, mid-lingual and disto-lingual using UNC-15 probe |
