statement of problem: physiologic pigmentation of oral mucosa is considered as a prevalent entity among black people and those having relatively dark skin. gingival physiologic pigmentation may cause problems for some patients specially ladies as far as esthetics is concerned. to overcome the issue, the surgery might be suggested which can cause some problems due to its side effects. cryotherap...

The pigmentation of human gingival tissue is derived from melanin granules, which are synthesized in the melanosomes of melanocytes [1,2]. The nicotine present in tobacco activates melanocytes to promote melanin secretion [3]. Therefore, the melanin pigmentation in gingival tissues has a strong correlation with smoking [4,5]. In 1977, Hedin et al. [5] first reported that smokers showed more pig...

OBJECTIVES Melanin pigmentation is present in the human inner ear. In this study, we quantify the melanin pigmentation in the vestibular system and examine racial differences of vestibular melanin pigmentation using human cadaveric temporal bone specimens. STUDY DESIGN Basic research. SETTING Laboratory. SUBJECTS AND METHODS Light microscopy was used to examine specimens from 40 left temp...

Smile is an expression of happiness, self-confidence, kindness and beauty. Along with teeth and lips, gingiva is also a vital component of smile. Melanin induced gingival hyper pigmentation may appear un-aesthetic especially when it is associated with high smile line, upper anterior labial segment and is uneven in appearance. It affects individuals from all races. Generally, it is believed that...

Background: Melanin pigmentation of the gingiva occurs in allethnicities. Excessive pigmentation is an esthetic concern thathas increased awareness about depigmentation procedures. Thepurpose of the present study was to correlate the skin color andgender with the intensity and distribution of gingival melaninpigmentation in a group of South Indians for treatment strategies.Method: Two hundred m...

For centuries skin pigmentation has played a major societal role, and genetic disorders of skin pigmentation have always evoked the curiosity of both laypersons and physicians. Normal skin pigmentation is a complex process that begins with the synthesis of melanin within the melanocytes, followed by its transfer to neighboring keratinocytes where it is translocated to the upper pole of the nucl...

Gingival hyperpigmentation is seen as a genetic trait in some populations irrespective of age and gender, hence it is termed physiologic or racial gingival pigmentation. Melanin, a brown pigment, is the most common natural pigment contributing to endogenous pigmentation of gingiva and the gingiva is also the most predominant site of pigmentation on the mucosa. Melanin pigmentation is the result...

Skin color in animals is richer than human beings and is determined by different types of pigments. Melanin is the key pigment responsible for the diverse pigmentation found in animal and human skin, hair, and eyes. Melanin pigment is synthesized by melanocytes and is consecutively transferred to adjacent keratinocytes; here, it acts as an internal sunscreen to defend from ultraviolet (UV) dama...
