Abstract:

Background and objectives: Pigmentation of the oral mucosal is commonly encountered and constitutes a variety of clinical presentation that can be physiological, systemic disease, post inflammatory, drugs, smoker melanosis, hemoglobin and iron association, melanoacanthoma, melanotic macule, Malignant Melanoma, amalgam tattoo and idiopathic. This mucosal discoloration may arise from either endogenous pigments or exogenous materials and they are classified as melanocytic and non-melanocytic pigments in origin.

Abstract:

Extrinsic pigmentations can be caused by food residues, medicinal substances and bacteria, forming deposits that overlap the enamel surface. Commonly, these black extrinsic pigmentations may be related to the presence of chromogenic bacteria in the nocturnal biofilm. The objective of this study was to report a case of pigmentation in primary teeth. This is a study with a qualitative approach and observational/descriptive objective. A survey was carried out in the municipality of Mato Verde-MG at Faculdade Verde Norte (FAVENORTE). A 5-year-old patient attended the FAVENORTE dental clinic accomp

Abstract:

Mucosal melanoma of the oral cavity is a rare but highly aggressive neoplasm. However, the clinicians need to be aware of the other and more frequent etiologies of intraoral pigmentation, such as amalgam tattoos. As amalgam has been extensively used for dental restorations and can cause pigmentations in the oral mucosa, this is a differential diagnosis not to be forgotten. We describe the characteristics of these two phenomena and present a case vignette illustrating the differential diagnostic issues. Other causes of intraoral pigmentation are summarized.

Abstract:

Introduction: An amalgam tattoo is the most common form of exogenous oral pigmentation caused by the diffusion of dental amalgam into the soft tissue. Observation: Here we describe a case of diffuse pigmentation of amalgam on the hard palate. Discussion: Mucosal hyperpigmentation can occasionally be confused with melanotic lesions, thereby requiring a biopsy for differential diagnosis. Once the diagnosis of an amalgam tattoo has been established, the removal of the lesion is not necessary, except for aesthetic reasons.

In contrast, melanin which is synthesized by melanocytes, is a true pigment and usually imparts a brown, blue or black appearance of the mucosa.

The aim of the study was to analyse the awareness on applications of photodynamic therapy in dentistry among undergraduate dental students. A questionnaire was prepared and administered to 100 participants through Google forms - an online survey platform. Th

Objectives: To know the level of cotinine concentration in the saliva of children exposed to secondhand smoke and know the link between smoke exposure and gingivitis. Materials and Methods: The study was conducted on 100 children from Riyadh Colleges of Dentistry and Pharmacy between the ages of 6 - 12 years. A questionnaire was conducted on the parents of the children to find out their smoking behavior. The sample (children) was separated into two categories: category (A) children exposed to secondhand smoke as a test sample and numbered 50 children (23 boys and 27 girls), category (B) childr

Concerns are emerging that young female may get dental and oral illnesses as a result of Bandung City's growing female smoking population. Numerous studies have demonstrated that smoking cigarettes can harm a variety of organs, and that female are more susceptible than men. This study aims to determine the difference in gum morphology, calculate the percentage of buccal mucosal epithelial cell abnormalities, and compare cytometric buccal mucosal epithelial cells in female smokers and nonsmokers.

Abstract:

Although the colour of the gingiva plays a vital part in overall aesthetics, the ideas and strategies for treating problems caused by gingival melanin pigmentation are still being worked out. Clinicians are confronted with obtaining acceptable gingival aesthetics as well as resolving biologic and functional difficulties as aesthetics has become an important element of dentistry. This case report discusses three different de-epithelization treatments that have been effectively utilised to treat gingival hyperpigmentation caused by excessive melanin deposition, as well as the importance of havin

Abstract:

Diode lasers are one of the most widely used modalities in soft tissue dental surgery. Recent advancements have expanded the clinically useful emission spectrum of diode lasers to include the blue light region, corresponding to wavelengths such as 445 and 450 nm. The melanin present in hyperpigmented gingiva acts as a chromophore and absorbs laser energy, thus facilitating the denaturing of melanin-containing cells in the gingiva. This paper presents a case of ethnicity-related gingival hyperpigmentation that was successfully treated using a 445 nm blue wavelength soft tissue diode laser by no

Dyskeratosis congenital (DC) is the first genetic syndrome described among telomeropathies. Its classical phenotype is characterized by the mucocutaneous triad of reticulated pigmentation of skin lace, nail dystrophy and oral leukoplakia. The clinical presentation, however, is heterogeneous and serious clinical complications include bone marrow failure, hematological and solid tumors. It may also involve immunodeficiencies, dental, pulmonary and liver disorders, and other minor complication. Dyskeratosis congenita shows marked genetic heterogeneity, as at least 14 genes are responsible for the

Initial caries corresponds to the ICD-10 code – K 02.0 «enamel caries, white (chalky) spot stage» or – K 02.3 «suspended caries» in the form of a pigmented spot on the teeth. If caries in the form of a white spot is not always easy to diagnose and patients rarely seek dental care, then suspended caries is visually detected quite easily, especially with dark pigmentation, which worries patients, so the number of visits to the dentist in this pathology increases dramatically. At the same time, it can be considered that the initial caries goes through several stages in its development, which are
