The more involved health professionals are in general and specific health problems of their patients, the better the condition of this health promoter.The speech therapist is undoubtedly one of the great pillars of quality made health.The objective of this study is to report by means of a systematic review, information on the main oral diseases affecting pediatric patients, contributing to the growth of knowledge and the advancement of speech therapy.

METHODS
For the development of this study of oral lesions that are more common in childhood and of interest to speech therapy, scientific literature searches were conducted in the following online databases/search portals: PubMed/ Medline, SciELO, Lilacs and Bireme .The descriptors and phrases used during searches in databases were: oral lesions, oral lesions in children, oral diseases in children, mucocele, candidiasis, ranula, primary acute herpetic gingivostomatitis, and geographic tongue.These descriptors were used in Portuguese and English.Only made use of the articles published in the last 10 years, which correspond to the years 2001 to 2011, in Portuguese and English and who suffered on relevance to the topic searched.In the initial analysis were obtained 98 articles; after exclusion of articles published before 2001, which treated the lesions exclusively in adults, which were published in languages other than English or Portuguese and does not contemplate the full text.After careful re-evaluation, a total of 31 articles met the established criteria.The articles were studied, complete, compiled from the central axis of the research.

LITERATURE REVIEW Mucocele
Mucoceles are cysts formed from obstruction of the excretory ducts of small accessory mucous glands of the oral cavity.Two phenomena are responsible: the mucus extravasation and mucus retention cyst.And, the first is the most common and is basically related to an injury in the excretory duct of the salivary gland; results in mucus extravasation at the adjacent soft tissues.Often, the lesion is caused by trauma.The second appears after a partial or complete obstruction of the excretory duct as an example, the calculation that causes retention of secretion 8,12 .
The injury has no predilection for any genre.It can appear in any region that homes to a minor salivary gland, being more common in lower lips.Patients with anterior overbite, sharp overjet and upper anterior and superior dental protrusion are more prone to trauma in the lower lip 9,[12][13][14] .
The clinical features may vary.The more superficial lesions are rounded, floating, slightly bluish or translucent, painless format.The deeper lesions have similar coloring to the local mucosa.The size ranges from a few millimeters to several centimeters 8,9,13 .
And extensive lesions located in certain anatomical positions can bring harm to speech and chewing; highlighting the essential knowledge of the speech therapist about this intraoral pathology.Treatment consists of surgical removal.During surgery, should be also removed the minor salivary glands that surround the mucocele, in order to avoid recurrence 12,14 .

Candidosis
Candidiasis or "thrush" is the most common fungal infection in pediatric patients.It is caused by Albicans candica, fungus that is a member of the oral microflora in most healthy people 3,15 .Some local factors may predispose to the development of oral candidiasis, such as dry mouth, poor oral hygiene, anemia, chronic diseases, viral infections, chronic use of antibiotics and corticosteroids.Newborns and children are particularly susceptible to the disease 16,17 .
It may present different clinical forms, such as: 3,15,18 : Pseudomembranous candidiasis is the most common form of the disease, popularly known as 'thrush'.Clinically, it is possible to observe the presence of white or yellowish plaques that are easily removed.There are more frequent in the buccal mucosa, tongue and palate.It is common in newborns as a result of the immune system undeveloped.
Candidiasis Erythema is more prevalent in patients with chronic diseases, and debilitating immune low.The intraoral examination shows erythematous plaques with red dotted aspect, there is a predilection for the dorsal surface of the tongue.
Chronic Candidiasis Hyperplasic, characterized by the presence of white patches that cannot be removed by scraping.This is the least common form.Such lesions are usually located in the anterior region of the oral mucosa and may not be clinically distinguished from common leukoplakia.
Mucocutaneous candidiasis -is a serious oral form, with the majority of cases are sporadic, although it was found a pattern of autosomal recessive inheritance in some families.Normally the immune problem becomes evident early in life, when the patient begins to develop Candida infection in the mouth, nail, skin and other regions.

Pediatric patients with candidiasis complain of pain and burning in the regions of the lesion, with consequent difficulty feeding.When exacerbated, injuries can attack the throat and tongue, also hindering speech.The treatment consists in the use of specific antifungal agents.In children, Nystatin topical presents good therapeutic results 16,19 .

Ranula
Ranula is the term used by the condition to distinguish mucoceles arising in the mouth floor.The ranulas can give up the mucin extravasation of the submandibular duct or minor salivary glands in the floor of the mouth.May be associated with bacterial infection causing pain, fever and severe discomfort, and a great salivary calculi can cause this injury [20][21][22] .
The clinical presentation is to increase the volume mouth floor, and as the mucocele, its color can vary from light blue pink 21 .
Children with ranula medium and/or large sizes have difficulty in speech caused by changing the position of the tongue.The treatment consists in removing the Ranula and/or sublingual gland Marsupialization 7,9,22 .
