This study aimed to investigate the accuracy of gingival thickness measurement by two methods of clinical evaluation and intraoral ultrasonography. The gingival thickness was measured in the midbuccal area of the right maxillary lateral incisor and first molar teeth in 30 individuals. For clinical measurement, a #15 K-file with rubber stops was vertically inserted 2 mm apical to the gingival margin and the length of the file in the tissue was measured using a digital caliper. Ultrasonographic measurement was performed using an intraoral probe on the gingival surface in the midbuccal area, at the entry point of the file. Statistical analysis was performed by paired t-test, correlation coefficient, and receiver operating characteristic (ROC) curve (α = 0.05). In the anterior region, the mean gingival thicknesses using ultrasonography (1.517 ± 0.293 mm) and clinical evaluation (1.610 ± 0.272 mm) were not significantly different (p = 0.434). In the posterior region, the mean gingival thicknesses were significantly different between ultrasonography (1.372 ± 0.442 mm) and clinical evaluation (1.626 ± 0.310 mm) (p = 0.006). The area under ROC curve values for ultrasonographic measurements in the anterior and posterior regions were 0.681 and 0.597, respectively. The use of ultrasonography with an intraoral probe has acceptable accuracy for the determination of gingival thickness, especially for the anterior regions. [ABSTRACT FROM AUTHOR]

Harmony between facial complexion and gingival health goes hand in hand. Gingival depigmentation is an aesthetic correction of hyperactive melanocytes in gingival tissues that lead to hyperpigmentation. Current study compares depigmentation, pain scores, and itching with scalpel technique and nonsurgical intramucosal Vitamin C injection. 30 individuals in the age range of 18–40 years conscious of dark gums were randomly allocated to test and control group by lottery method. Thorough Phase I therapy was performed one week before the procedure. Area and intensity of depigmentation were evaluated preoperatively and postoperatively; pain score, itching, and repigmentation percentage were the postoperative parameters. After 24 hrs, test group showed significantly lesser VAS score for pain as compared to control group. There was no statistically significant difference in preoperative area of pigmentation between the test and control group (p = 0.936). Postoperatively also, there was no statistically significant difference in area of pigmentation between the test and control group (p = 0.932). For comparing area of pigmentation, an independent t-test was applied and Mann–Whitney test was used for differentiating the intensity of pigmentation, repigmentation, and VAS score between the groups. The study concluded that Vitamin C mesotherapy and scalpel technique showed comparable results in reduction of areas and intensity of gingival hyperpigmentation. [ABSTRACT FROM AUTHOR]

Gingival melanin hyperpigmentation is a para-physiological condition that may have a negative impact on smile esthetics. In the present study, the use of the Q-Switched Nd:YAG laser, according to a defined protocol, was proposed to treat Gingival Melanin Hyperpigmentation with a transepithelial approach. A total of 10 Patients with different grades of gingival hyperpigmentation were treated with Q-Switched Nd:YAG in one to four laser sessions without local anesthesia. The grade of depigmentation was evaluated by comparing Oral Pigmentation Index (OPI) and Melanin Pigmentation Index (MPI) at baseline and three weeks after the laser session. Additionally, oral discomfort rated by the Numeric Rating Scale (NRS) was recorded one, three, and five days after the procedure. Complete depigmentation was achieved in all cases. Patients reported no-little discomfort (NRS 0 to 3) during the laser session that lasted a maximum of five days. No major complications were reported, and no recurrences were observed at least after one year of follow-up. In addition, patients were available to be re-treated if necessary. These findings suggested that the Q-Switched Nd:YAG could be an effective and well-tolerated approach in the treatment of gingival melanin hyperpigmentation. [ABSTRACT FROM AUTHOR]
