 Welcome back to a new session on dentistry and more. So today we have a pedodontic topic that is natal and neonatal teeth. So we are familiar with these terminologies natal and neonatal teeth. It's nothing but teeth which are present in the newborns. So let's see what is natal teeth. Natal teeth, the teeth which are present at birth and neonatal teeth, teeth which are present in the newborns within 30 days. So that is the difference between natal and neonatal teeth. So let's see what are the etiology of these special phenomenon. The first one is febrile incidence, then the hormonal stimulation. So this could be mostly due to the hormonal differences, hormonal imbalance and also hereditary factors are also involved. So it mostly depends on the osteoclastic activity of that particular tooth. So while coming to the incidence, the natal teeth which are seen among 1 out of 1000 newborns and neonatal teeth is 1 out of 30,000 newborns. So the most common tooth involving these two phenomena are mandibular incisors that is 85% of the conditions are seen with respect to the mandibular incisor. Then comes the maxillary incisors that is 11% then the mandibular cuspids that comes the least 3%. So natal and neonatal teeth are mostly associated with certain syndromes. The syndromes are contralectodermal dysplasia, regaffida syndrome, elisvan creval syndrome. So these three syndromes and many other syndromes are mentioned only in the very important three contralectodermal dysplasia, regaffida syndrome and elisvan creval syndrome. So what are the harmful effects of this natal and neonatal teeth? The most common harmful effect is the laceration of baby's tongue that is lingual surface or the ventral surface of the baby's tongue will be continuously injured. Because of this sharp edges of this teeth mostly the mandibular incisors and mostly there is feeding problems because of the interruption of this teeth and the mother also feeling having problems with feeding of the babies. So these are the common harmful effects associated with natal and neonatal teeth. So the management is first we need to take radiograph and make sure that whether it has root or not and do very careful extraction if it is very mobile and while doing extraction we have to make sure that we are not leaving any residue within the socket because if residue is there it may again start creating tissues and becoming tooth like structures within the socket and again it will create problems for the baby and mother. So if it is mobile and with x-ray with the help of x-ray we can do extraction with proper curatage of this root socket and if it is not mobile and if it has proper roots and if the roots are starting to grow then we can leave behind and we can let the growth of this particular tooth if it is not interrupting any of the babies and mothers feeding function if it is too much interrupting and the baby's tongue is too much lacerated and feeding problem persists we have to go for extraction anyway. So otherwise we can leave it behind and let the tooth grow. So always while doing extraction we should always protect the airway using a goes or any other thing because there is chance of falling back the tooth to the airway. So always we should make precautions while doing extractions. So let's recap once natal and neonatal teeth this is seen at birth natal neonatal within 30 days and the etiology febrile incident so hormonal stimulation hereditary and always depends on osteoclastic activity one in thousand incidents and one in thirty thousand for neonatal teeth. Most commonly seen in mandibular incisors then maxilla incisors and mandibular caspids syndrome are control ectodermal dysplasia or ecafidae syndrome and elisone crevole syndrome harmful effects are lacerations of ventral side of the tongue of baby and feeding problems while management we can do extraction if there is too much interruptions for the baby and the mother feeding problems and always protect the airway while doing extraction. So I'll come up with a new session on dentistry and more thank you.
