Most affected infants have multiple, scar-like, circular depressions on both temples (bitemporal). These marks closely resemble those made when forceps are used to assist delivery. [3] The range and severity of symptoms may vary from case to case.
The signs of late congenital syphilis tend to reflect early damage to developing tissues that does not become apparent until years later, [20] such as Hutchinson's triad of Hutchinson's teeth (notched incisors), keratitis and deafness. [21] [22] Symptoms include: [21] Blunted upper incisor teeth known as Hutchinson's teeth, or mulberry molars [7]
These teeth are functional but can be fixed with crowns, bridges, or implants. [4] Just above the gum line, the mulberry molar looks normal. A deformity becomes apparent towards the cusp or the top grinding surface of the tooth. Here, the size of the mulberry molar is diminished in all aspects, creating a stumpy version of a conventional molar.
Hutchinson's teeth resulting from congenital syphilis. Hutchinson triad is a triad of signs that may be seen in late congenital syphilis, including: interstitial keratitis, malformed teeth (Hutchinson incisors and mulberry molars), and eighth nerve deafness. [1] [2] Late congenital syphilis typically manifests after 2 years of age. [3]
Hutchinson's teeth is a sign of congenital syphilis. [1] Affected people have teeth that are smaller and more widely spaced than normal and which have notches on their biting surfaces. [2] It is named for Sir Jonathan Hutchinson, a British surgeon and pathologist, who first described it. [3] Hutchinson's teeth form part of Hutchinson's triad. [2]
According to a recent study, baby teeth contain an abundance of stem cells, a very special type of cell that can potentially grow replacement tissue in the body and cure a number of diseases.
The neonatal line is a particular band of incremental growth lines seen in histologic sections of both enamel and dentin of primary teeth. It belongs to a series of a growth lines in tooth enamel known as the Striae of Retzius denoting the prolonged rest period of enamel formation that occurs at the time of birth.
Natal and neonatal teeth are an anomaly that involves teeth erupting in a newborn infant's mouth earlier than usual. The incidence ranges from 1:2,000 to 1:3,500 births. Natal teeth are more frequent, approximately three times more common than neonatal teeth. Some authors reported a higher prevalence in females than males.
