The oral clinical examination can be a challenge for everyone in younger children. But with the right preparation, a positive attitude and a confident approach, you’ll be ready for the challenge. It is important to know that the physical findings are unique to the pediatric population, and understand how they can change depending on the age of the child.- The sequence and focus of the test vary by age. We must create a calm, harmonious, affectionate environment for the exam, with a lot of privacy so that modesty is respected.- Young children often need persuasions and simple explanations before cooperating with the examination of the mouth and throat. Most children show their teeth right away. If the child resists squeezing the teeth, they can be separated gently with a depressor, we must use gloves of recognition for that exam in addition to maintaining an adequate hygiene.We must be careful when examining the mouth when there are signs of respiratory distress, high fever, drooling and intense apprehension, as these may be signs of more severe respiratory infection. Children with cleft lip and / or cleft palate (CLP), for example, have difficulty feeding, require speech therapy and are at increased risk of otitis media. In addition, they are at risk of long-term psychosocial effects. A systematic review found an association between CLP and behavioral problems, dissatisfaction with facial appearance, depression and anxiety, but the evidence was inconsistent. In a subsequent case-control study, children and young adults with CLP had more behavioral problems, more depressive symptoms, mocked more often and were less happy with their facial appearance and speech than children and young adults without CLP. Dental caries is the most common chronic childhood disease and its effects go far beyond the oral cavity. Moderate or severe caries, particularly in young children, can affect nutrition, growth and development.Babies are born with their first (first) set of teeth formed under the gums. Usually, these teeth do not begin to enter the mouth until the child is between six and eight months of age. At three years, the 20 primary teeth should be in the mouth. The first (primary) teeth of a child is very important. These teeth help a child eat and talk. They have room for permanent teeth.Around six years of age, a child’s mouth will begin to grow to make room for permanent teeth. Each baby tooth will be replaced by a permanent tooth. The permanent teeth begin to enter the mouth between the ages of five and six and will continue around the age of twenty-one.It is very important to always remember that in the pediatric examination the mouth and throat should be performed at the end to avoid crying and discomfort of the child and thus not interfere with the rest of the physical examination. The examiner should make sure that his hands are warm to avoid unwanted reactions in the child that interfere with the exam. In the infant and young child, the patient usually cooperates little and generates anxiety and crying in them, in the older child and the adolescent, we must explain the procedure and how to help us to do the exam quickly and effectively.
