Teeth erupting within the first month after birth are known as neonatal teeth. Incidence of neonatal teeth is very low. Neonatal teeth erupt in various regions of the maxillary and mandibular arch. Incidence of neonatal teeth in molar region is only 1%. A case of an unusual neonatal tooth in the maxillary molar region has been presented.

   Introduction Top

Massler and Savara [1] suggested that natal teeth are present in the oral cavity from birth; on the other hand, neonatal teeth erupt during neonatal period, i.e., within 30 days after birth.

Incidence of natal teeth is more than neonatal teeth and its ratio varies from 1: 2000 to 1: 6000. [1],[2],[3],[4],[5],[6],[7],[8] Bodenhoff [9] reported the incidence of natal and neonatal teeth to be 0.3-0.5%.

Natal and neonatal teeth erupt in the same position as that of decidu­ous teeth in the arch, more common in mandibular arch than maxillary arch, and are more common in the incisor region than the canine and molar regions. Various investigators noted that 85% erupt in mandibular incisor region, 11 % in maxillary incisor region, 3% in mandibular canine region and 1% in maxillary canine and molar regions. [1],[2],[8],[9]

Shor and Hajare [3] noted that incidence is more in girls than in boys.

Sponge and Feasby, [4] classified natal and neonatal teeth; as mature or immature.

Etiology of natal and neonatal teeth is not known. Various investigators have put forth various views.

During initiation and proliferation stage excessive development causes formation of natal teeth, [10] Hyperactivity of osteoblastic cells within the tooth germ may also be a reason, as suggested by another group of investigators. Superficial positioning of tooth germs during developmental period may also be a reason. [11] Oral pathologists suggested endocrinal disturbances, or they may be associated with various syndromes. [12],[13],[14]

The incidence of natal/ neonatal teeth in Muslim children is more than Hindu chil­dren. [15]

Crowns of these teeth are like those of normal teeth, without any radicular portion due to lack of root formation. [16],[17] Ground section of natal and neonatal teeth showed hypomineralized enamel, irregular arrangement of enamel rods, irregular dentino-enamel junction, dentinal tubules, more cellular and numerous vascular channels with endothelial cells and large pulp chamber. [18]

Present paper aims to evaluate means to prevent various complications occurring due to an unusual neonatal tooth in maxillary arch (in first molar region) in a 3-month-old Bengalee child.

   Case Report Top

Apparently good health aged 3 months male child came to our clinic with complaints of whine type crying throughout the day, mainly at the time of feeding. On oral examination, an unusual neonatal tooth was found in maxillary arch (in the left deciduous 1 st molar region), which had caused mild ulceration in the mandibular arch and tongue [Figure - 1]. After thorough hematological examination, the neonatal tooth was extracted under proper aseptic conditions. Extracted tooth was rootless [Figure - 2].

   Discussion Top

Teeth appearing in the oral cavity within 30 days of birth are known as neonatal teeth. Incidence of this type of teeth is very low. Incidence of neonatal teeth in maxillary arch in the molar region is only 1%. [1],[2],[8],[9]

Etiology of natal and neonatal teeth is still unknown. Various investigators have postulated various views. Hyperactivity of osteoblastic cells within tooth germ during initiation [10] or proliferation stage of develop­ment of tooth may be the reason. [10]

SEM study on neonatal teeth of two female babies with cleft lip and cleft palate noted irregular hypoplastic superficial enamel layer, regu­lar dentinal layer with arrangement of dentinal tubules-like normal teeth and with only 300 µ root formation. [12] Anegundi et al. [18] also observed similar findings.

Early eruption of neonatal tooth causes ulceration in the opposite arch, gum pad and tongue due to sharp edge of tooth.
