ABSTRACT
@#Gingival pigmentation is a nonplaque gum disease. Patients are often afraid to communicate with others because of gum color problems, which affect the social and mental health of patients. The commonly used treatment methods for gingival pigmentation include scalpel excision, gingival grinding, laser therapy, cryosurgery and electrosurgery. In this paper, the progress of gingival pigmentation treatment was reviewed in terms of bleeding, pain, tissue healing and recoloring. The results showed that the clinical effect of laser treatment was better. Among them, the semiconductor laser had more advantages in reducing bleeding, pain and the restaining rate, while the Er:Cr:YSSG/Er:YAG laser performed better for promoting tissue healing. Clinicians can choose the best kind of laser to use according to the actual situation. For patients with thin gingival biotypes, floating gingival transplantation or substitute materials can be selected to restore the gingival morphology. With the in-depth study of melanin regulation mechanisms, various drugs, such as ascorbic acid, natural peptides, synthetic peptides and derivatives, may be the main research direction for the treatment of gingival pigmentation in the future.
ABSTRACT
@#Gingival pigmentation(GP) manifests as dark pigmentation spots, such as black or brown spots, in the gums. It is mostly caused by the deposition of melanin particles secreted by melanocytes on the gingival epithelium. The influencing factors may be divided into two categories, exogenous and endogenous. Exogenous factors include heavy metals, tattoos, smoking or drug use, and endogenous factors are related to certain diseases. The clinical grading of GP helps make a reasonable assessment of the necessity of treatment and prognosis. The Dummett-Gupta oral pigmentation index is a commonly used grading method, and the new grading method formed by combining the etiology and clinical manifestations described the patient’s situation more comprehensively. It is necessary to ask for a detailed medical history, complete examination, and correctly differentiate between physiological GP and GP caused by pathological state. Laser treatment is the currenttreatment with a better treatment effect and higher patient acceptance, and it is more comfortable and convenient, including diode laser, Er: YAG laser, and Nd: YAG laser, etc. This article summarizes the formation factors, clinical manifestations and treatment methods of GP to provide ideas for the clinical diagnosis and treatment of GP.
ABSTRACT
This study was carried out to compare the treatment outcome after application of surgical scalpel and sieve methods of diode laser for depigmentation techniques with one year follow up period. METHODSThis was a comparative split mouth intervention study with follow up period of one year. A total of 5 systemically healthy patients, were enrolled in this study. Right and left quadrant were divided into Group A and Group B. In Group A, depigmentation with Sieve method of diode laser and in Group B depigmentation with surgical scalpel technique were used. Dummett Oral Pigmentation Index (DOPI) and Verbal Analogue Scale (VAS) Questionnaires were used to assess the intensity of gingival pigmentation and the pain intensity of the patients respectively. Data was analyzed using SPSS version 2.5 and P value of <0.05 was considered as statistically significant. RESULTSThe pain intensity in Group B (mean rank 1.60, 4.0) was high as compared to Group A (mean rank 0.0, 2.0) at 2 weeks and one month follow up and the results were statistically significant. Group A (mean rank 0.20, 0.80) showed better depigmentation outcome compared group B (mean rank 1.0, 1.80) at six months and one year and the results were statistically significant. CONCLUSIONSSeive method of diode laser therapy showed a significant improvement in gingival pigmentation as well as reduction in pain intensity as compared to surgical scalpel technique.
ABSTRACT
Gingival hyper pigmentation is of prime aesthetic concern reported by many young patients, in day to day dental practice. Gingival depigmentation is a periodontal plastic surgical procedure whereby the gingival hyperpigmentation is removed or reduced by various techniques. Recently, laser ablation has been recognized as one of the most effective, comfortable and reliable techniques. The present case report showcases the effectiveness and thoroughness of gingival depigmentation and crown lengthening carried out with a diode laser. Depigmentation with , diode lasers can be used in periodontics because of their excellent soft tissue ablation and haemostatic characteristics.
