A comprehensive survey of natal and neonatal teeth in newborns.

OBJECTIVE: To evaluate clinical and histological characteristics and determine the incidence of natal/neonatal teeth in a large Turkish population. SUBJECTS AND METHODS: Among 17,829 newborns, who were hospitalized at the Neonatal Clinic of a governmental Children's Hospital between 2005 and 2011, 27 neonates were diagnosed with erupted teeth, which were examined in terms of location, clinical appearance and mobility. Besides histological evaluation, a positive family history was also recorded. The variables were analyzed using Chi-square test. RESULTS: Thirty-two natal/neonatal teeth were observed in 27 infants. The incidence of both natal and neonatal teeth was found to be 1:660, while the incidences were separately recorded as 1:1,048 and 1:1,782, respectively. The histological examination revealed a thin hypoplastic enamel layer and a normal dentin layer. There was no difference between the two genders in terms of natal/neonatal tooth type, positive family history and tooth morphology (p > 0.05); or between normal and conical shapes with regard to natal/neonatal tooth type, positive family history and tooth color (p > 0.05). CONCLUSIONS: This study exhibited a higher incidence in natal teeth than neonatal teeth. Macroscopic features were not found to be positively related to gender and tooth type.

Bohn's nodules: peculiar neonatal intraoral lesions mistaken for natal teeth.

Inclusion cysts of transient nature during the neonatal period are developmental lesions, which are seen in the oral cavity of the newborn infant. These lesions are classified into three subtypes according to their localizations. When noticed by the anxious parents on the gingival surfaces, they are often mistaken for natal teeth, which lead to seeking medical attention. Herein, we describe a newborn infant with Bohn's nodules to increase the awareness of the physicians to this benign, self-limiting lesion.

Neonatal sublingual traumatic ulceration - case report & review of the literature.

Traumatic ulceration of the ventral surface of the tongue is a rare condition observed in neonates with natal or neonatal teeth. These lesions are initiated and exacerbated by the continuous contact between the tongue and natal/neonatal teeth during physiologic activities such as suckling and swallowing, which in turn may interfere with proper feeding, putting the neonate at risk for nutritional deficiencies. Sublingual traumatic ulcers may also be the presenting sign of an underlying developmental or neurologic disorder. This case report details the management of a sublingual traumatic ulcer in a 20-day-old infant, along with a review of the treatment modalities available for management of this condition, especially in neonates.

Asymmetric crying facies with a couple of primary mandibular central incisor and 22q11 deletion.

Facial asymmetry present only on crying has been described as a separate entity and termed asymmetric crying facies. The cause of the facial asymmetry in this disorder is congenital absence or hypoplasia of the depressor anguli oris muscle at the corner of the mouth. This defect is associated at times with major congenital anomalies, most commonly in the cardiovascular system. Chromosome 22q11 microdeletions in cases with ACF have been reported. We report a newborn infant who had ACF associated with a couple of primary mandibular central incisor teeth and chromosome 22q11 microdeletion. This clinical sign in association with ACF has not been previously described.

Natal teeth: report of two cases.

Presence of teeth at birth or within a month post-delivery is a rare condition. We report here 2 cases to highlight their clinical features and discuss their possible treatment. A 7- days old female newborn with two mandibular central incisors, noticed by the parents at birth, with complaint of continuous crying, inability to suck milk and causing discomfort to the mother. The left incisor was highly mobile justifying its extraction. The second case was a female newborn referred 2 hours after delivery, for a brownish highly mobile mandibular incisor noticed by the pediatrician. Extraction was immediately made to avoid the danger of aspiration. This phenomenon can lead to complications either local such as pain on suckling or general such as undernutrition or asphyxia by aspiration. The decision to maintain or remove these teeth should be assessed in each case independently, based on degree of mobility and interference with breastfeeding.

Pulp polyp associated with a natal tooth: case report.

Natal teeth are an infrequent occurrence at birth. Often these teeth are extracted because they are very mobile and pose a risk of aspiration. This is a rare case in which a natal tooth was extracted by the pediatrician with his fingers. A root fragment remained and out of this developed a large pulp polyp. This relationship has not been previously reported.

Supernumerary tooth with associated dentigerous cyst in an infant. A case report and review of differential diagnosis.

This paper reviews the topic of dental structures present at birth or erupting prior to the deciduous incisor teeth. A literature review shows a prevalence of one in every 2000 live births. At this rate of occurrence it is likely that the general dental practitioner may be called upon to offer advice. This review is supported by the presentation of an unusual case of a supernumerary maxillary incisor tooth with the hallmarks of a neonatal tooth and the development of a soft tissue dentigerous cyst. The differential diagnosis of soft and hard tissue swellings in infants is also presented together with rare syndromal associations of natal and neonatal teeth.

Neonatal teeth in X-linked Opitz (G/BBB) syndrome.

Two male siblings are described with a clinical and molecular diagnosis of X-linked Opitz (G/BBB) syndrome and the previously unreported feature of neonatal mandibular incisors.

[Natal and neonatal teeth]. / Natale und neonatale Zähne.

Natal teeth have been defined as teeth which are present at birth, while neonatal teeth erupt during the first 30 days. Their occurrence is rare, the prevalence ranges from 1:2000 to 1:3000 with a higher frequency in the lip and palate clefts and syndroms. In about 85% natal or neonatal teeth are lower central incisors (60% in pairs), rare are upper teeth, molars and multiple teeth. In almost 90% they are part of the deciduous dentition. A lot of possible causes of early eruption are discussed, but only the relation to hereditary factors seems to be evident. An autosomal dominant trait is often described. The appearance of these teeth is dependent on the degree of maturity, but most of the time it is loose, small, discoloured and hypoplastic. Histologically, enamel hypoplasia with normal prism structure is apparent. No significant disturbances of the dentin structures are observed, only cervically dentin becomes atubular with spaces and enclosed cells. A large vascular pulp and failure of root formation are further investigations. Our microhardness measurements showed values from 24.3-32.4 KHN for enamel and 48.3-62.2 KHN for dentin, while normal deciduous teeth have an enamel hardness of 322.0 +/- 17.5 KHN. The thickness of enamel was never more than 280 microm compared to up to 1200 microm in normal teeth. This shows the retarded development of natal and neonatal teeth, because mineralization has not finished at the time of birth. In accordance with developmental age tooth structure and appearence are normal. In consideration of complications as Riga-Fede-disease, feeding problems, possibility of infection and hypermobility most of the time extraction is the treatment of choice, but in the interest of protecting the child this decision should be made carefully.

Complication After Extraction of Natal Teeth with Continued Growth of a Dental Papilla.

The purposes of this case report were to describe a growing two-cm gingival mass that developed after natal teeth were extracted in a four-month-old female patient, present a review of the literature on the growth of a gingival mass after the extraction of natal teeth, and illustrate the clinical and histological features that differentiate this condition from other types of gingival masses in infants. Histological examination of the excised mass revealed that it contained tooth-like hard tissue (regular and irregular dentin) that intermingled with bone, dental pulp, and fibrous tissue. We found eight cases from 1962 to 2009 in which a soft-tissue mass with dentin-like hard tissue or a tooth-like structure had developed after the extraction of natal teeth. Based on clinical and histological findings, we deduced that the mass was the result of abnormal growth of a residual dental papilla, including mesenchymal stem cells. Consequently, dentists, obstetricians, gynecologists, and pediatricians should be aware of this potential complication and observe caution before they extract natal teeth.

Residual neonatal teeth: a case report.

A case is presented in which an infant required extraction of 2 residual neonatal teeth. Some authors suggest routine curettage of the extraction sites of natal and neonatal teeth to prevent the development of residual teeth. In light of the rare occurrence of such residual teeth, this may represent overtreatment. Curettage at the time of extraction is recommended only in cases where the administration of an injectable local anesthetic is required because of greater gingival attachment.

Multiple anomalies of a newborn: report of case.

Described are four oral anomalies--natal teeth, palatal cyst, bilateral lymphangiomas of the alveolar ridge, and median alveolar notch--found in a newborn. Immediate and long-term treatment considerations are outlined.

Riga-Fedes syndrome: natal or neonatal teeth associated with tongue ulceration. Case report.

A case of natal teeth associated with traumatic ulceration to the ventral surface of the tongue (Riga-Fedes syndrome) in a four week old boy is presented. On radiographic examination, two teeth, present at birth, were found to be early erupted deciduous lower central incisors. A family history of natal teeth, all involving both lower deciduous central incisors associated with trauma to the tongue during suckling, was elicited. The ulceration healed over a period of four weeks using an innovative conservative treatment regime, involving the use of Stomahesive Wafer. Four months later the only sign of any previous pathosis was a fibrous scar on the ventral surface of the tongue.

Natal and neonatal teeth: review of the literature.

Child development from conception through the first years of life is marked by many changes. Tooth eruption follows a chronology corresponding to the date when the tooth erupts into the oral cavity. These dates have been established in the literature and are subjected to small variations depending on hereditary, endocrine and environmental features. At times, however, the chronology of tooth eruption suffers a more significant alteration in terms of onset, and the first teeth may be present at birth or arise during the first month of life. The expectations about the eruption of the first teeth are great and even greater when the teeth appear early in the oral cavity. The objective of the present study was to present a review of the literature with important aspects about natal and neonatal teeth.

Natal and neonatal teeth : a report of four cases.

Natal and Neonatal teeth although not unique anomalies, are observed in infants at birth or during the first 30 days of life. Here, the report of our four cases, in which the bilateral mandibular posterior natal teeth, which stands out to be a rare condition is presented. Etiological, clinical, histological features, complications and treatment modalities are discussed.

Unusual case of multiple natal teeth.

Natal teeth are defined as teeth that are present in the mouth at the birth, and the occurrence is rare. In the literature, few reports have described cases with involved multiple elements. This article describes an unusual case of a newborn with eleven natal teeth that belong to the primary dentition and the therapy utilized.

Natal maxillary primary molars: case report.

An unusual case of a newborn with two immature natal maxillary molars is presented. Clinical and histological examination showed that the teeth were rootless and incompletely mineralized. The patient was followed up during one year and we confirmed that the natal teeth were from normal primary series.
