Egyptians
Excavations of their pyramids shows that they paid great attention to dental care. In burial remains, mummies of the time had their teeth filled with gold restorations.
Methods of early times
Dentistry consisted primarily of removing teeth, holes were drilled in the skull near roots to allow infections to drain and most problems came from tooth preparation techniques
Hippocrates (460-377 B.C.)
Father of medicine who attempted to explain health and disease. He was the first to teach an educated method of medical care. He felt it was important to keep teeth in good condition and he developed his own toothpaste and mouth rinse. He wrote about formation, eruption, diseases of teeth, and methods of treatment. He designed some extraction instruments to make removal easier and safer. He advocated for physicians to have confidentiality with their patients and founded his Hippocratic Oath which is a basic code for ethics for medical and dental professionals to “do no harm” SHORTEN
Diocles of Carystus (384-322B.C.)

Dental Home
Relationship between the dentist and the patient inclusive of all aspects of oral health care. Establishing this at a young age gives the child an environment to grow and develop while the pediatric dentist can provide information and preventative care.
Caregiver’s Importance
It is important to involve the caregiver in every aspect of the child’s treatment and for the dentist to keep them educated about the child’s needs, including treatment of primary teeth to start a habit of good oral health.
Function of Primary Teeth
Mastication, nutrition, speech, and appearance are their functions, and neglect of them can result in pain, infection, and malocclusion. Early treatment/ proper care is less costly than waiting to get treatments such as orthodontics and endodontics.
Pediatric Patient
Needs at least one parent at their appointment, and their family’s attitude affects theirs. Their behavior may be based on emotional and environmental and they should be evaluated individually regardless of their physical develop and maturity.
Children with Special Needs:
Pediatric dentists are trained to treat patients with ADHD, down syndrome, autism, asthma, cystic fibrosis, etc. A complete medical history is important to prepare to address these needs.
Pediatric Dental Assistant
Person who is trained to engage the child during appointments to establish trust during a procedure. The procedures are similar to those for adults, but they must also monitor the child’s behavior.
Child Abuse and Dental Neglect
Something that must be reported with confidentiality by dentist and dental assistant in order for the child to have adequate function of the mouth without pain and infection.
Dental Caries
Infectious and communicable disease with multiple factors that progress the disease, but is preventable. S. mutans can cause these at an early age, and reducing sweets and increasing cleaning can delay the decay, and lack of these can add decay to newly erupting teeth. Left untreated, these may need extraction.
Early Childhood Caries (ECC)
Presence of one or more decayed, missing, or filled tooth surfaces in a child 71 months or younger. The front teeth are usually affected first before slight decay in the posterior teeth.
Infant Oral Exam
Visit to dentist when first tooth erupts, usually before first birthday before caries process to begin early oral hygiene and dietary habits.
Pediatric Charting
Children normally develop 20 teeth, universally labeled A through T where A-J are found on the upper arch, and K-T are on the lower arch, the first to erupt are usually lower central incisors. They are then replaced by succedaneous, or permanent teeth. The teeth that erupt not replacing primary teeth are nonsuccedaneous and are numbered 1-32.
Charting Present and Missing Teeth
Charting mixed dentition can identify primary teeth by size, shape, enamel composition, shallow pulp chamber, and root resorption on radiographs.
Pediatric Conditions and Abnormalities
Pediatric dentists will look for conditions both clinically and radiographically such as crowding which may indicate future orthodontic treatment. They can also find that thumb sucking leads to an open bite and skeletal problems and encourage the patient to stop habit.
Common Abnormalities
Short Frenum attachments on lips or tongue, enamel hypoplasia, primary and permanent supernumerary teeth, congenitally missing teeth, over retained and early loss of primary teeth, cysts and impacted teeth that cause tissue damage all of which affect the child’s developing permanent dentition.
Prevention
Includes five major points such as oral hygiene, dietary instructions, fluoride, sealants, and routine dental checkups.
Oral Hygiene Instructions
The pediatric dentist or assistant will demonstrate techniques for cleaning the mouth and erupting teeth, and the caregiver must do this daily to help with discomfort such as massaging gums and cleaning them with a soft washcloth. As more teeth erupt, a toothbrush may be used.
Sequelae
Consequences of a disease. Caries and its sequelae are among the most prevalent problems in children.
Pediatric Dietary Guidelines
Avoid frequent ingestion of sugars and carbohydrates and have a balanced diet of milk, meat, vegetables, fruit, and grain.
Infant over one year
Should be weaned off bottle/breast and be introduced healthy foods to learn to stimulate dentition. Sippy cups should be only used at meals, not bedtime to avoid decay.
Fluoride Varnish
Recommended for preschoolers and high risk caries patients and is an application of 5% sodium fluoride with resin base that causes varnish to remain on teeth and be brushed away the next day. Can be applied every three to four months from birth - adolescence.
Fluoride Application
2-5 year olds should get a pea-sized amount to brush teeth and avoid fluorosis from excess ingestion of fluoride. When applied by professionals, it has more concentrated solutions and gets delivered in a tray.
Dental Sealants
Thin coating of unfilled resin applied to pits and fissures of posterior permanent molars and premolars. Seals out germs and food particles from fissures in chewing surface of tooth and lasts up to 5-10 years.
Regular Checkups
Reinforces the need for good oral health from infancy to adulthood and monitors growth and development of dentitions. Also provides early intervention to dental decay by taking routine radiographs which can also see abnormalities.
Frankl Behavorial Rating Scale
A way to classify a child’s behavior during treatment by using four categories including definitely positive where the child enjoys the situation (4), positive where the child is willing to comply(3), negative where the child is reluctant and uncooperative(2), and definitely negative where the child refuses and is forceful(1).
Pediatric Communication
Number one tool in pediatric dental team for both caregiver and child during procedure. Positive approach should be taken by being truthful, making eye contact, maintaining control, and praising child at the appointment.
Communication
The act of passing along a message, transmitting an idea, or providing feedback
Components of Communication Process
Sender, message, channel through which the message is delivered, receiver, feedback
Sender
The individual who begins the communicative process by generating a message.
Stimuli to begin communication
