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.

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.

Dents natales, stigmatisation et prise en charge à Cotonou

Des études récentes ont montré que l'élévation des aminotransferases et l'infection par Helicobacter pylori aggravaient l'évolution de l'infection par le virus de l'hépatite B chez les porteurs chroniques. Le but de la présente étude était de rapporter les facteurs associés à une élévation des ALAT chez des patients porteurs d'une infection chronique par le VHB. PATIENTS ET METHODES : Cette étude transversale était menée de mai à aout 2017 dans la clinique Universitaire d'Hépato gastroentérologie du CNHU de Cotonou (Benin). Etaient inclus tous les patients porteurs chroniques d'Ag HBs reçus en consultation au cours de cette période. Tous les patients inclus avaient un examen physique, une exploration fonctionnelle hépatique, incluant les ALAT (N<40UI/L), la recherche de l'antigène de l'Helicobacter pylori dans les selles et la détermination de l'ADN du VHB par PCR. RESULTATS : Sur les 121 patients porteurs chroniques d'Ag HBs (M/F 84/37, sex ratio 2.11, âge moyen 42. 3±11.6 ans [18-74], 70 (57.9%) étaient infectés par Helicobacter pylori. La valeur moyenne des ALAT (en UI/L) était de 70.7 ± 99.9 [13 - 665]. Etaient associés à une élévation des Amino transférases, la présence d'une infection par Hp (89.1 ± 15.3) vs (43.48 ± 5), p = 0.01, l'âge (entre 20 et 60 ans vs âge <20 ans ou >60 ans (p=0.000). N'étaient pas statiquement associés, le sexe, l'indice de masse corporelle p=(0.12), la consommation d'alcool (p = 0, 81), ni le niveau de la charge virale ADNVHB (p=0.07). CONCLUSION : L'infection par Hp et l'âge sont des facteurs indépendants d'élévation des ALAT chez ces porteurs chroniques de l'Ag HBs. Une recherche systématique d'infection par Hp et son éradication devraient être indiquées avant le traitement éventuel de l'hépatite chronique B

Manejo de dientes natales y neonatales: reporte de dos casos / Management of natal and neonatal teeth: report of two cases

Los dientes natales son órganos dentarios que se presentan al nacimiento, y los neonatales son aquellos que erupcionan durante el primer mes de vida. La etiología exacta es desconocida. El manejo de estos dientes depende de múltiples factores. La extracción está indicada cuando eldiente es un supernumerario o presenta movilidad excesiva debido al riesgo de broncoaspiración. Cuando tienen ligera movilidad, generalmente se estabilizan conforme van erupcionando. El objetivo de este reporte es la presentación de dos casos clínicos de dientes natales yneonatales que se manejaron con abordajes diferentes, el primero demanera conservadora y el segundo con la extracción del órgano dental.

Natal teeth are those present at birth. Those erupting during the fi rst month of life are neonatal teeth. The etiology is not known. Natal teeth management is dependent on multiple factors. If the natal tooth is su-pernumerary, the treatment of choice is extraction; likewise, when the teeth are excessively mobile, extraction is indicated due to the risk of aspiration. When natal teeth are only slightly mobile, they often stabilize soon after eruption. The aim of this report is to present two cases of natal and neonatal teeth that were managed with different approaches; the fi rst with a more conservative treatment and the second one with the extraction of the teeth.

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.

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.

Dientes natales: reporte de caso y revisión de literatura / Natal teeth: Case report and literature review

Los dientes natales son aquellos dientes presentes en la cavidad bucal en el momento del nacimiento y que pueden generar una ulcera lingual denominada Enfermedad de Riga-frede interfiriendo en la alimentación del recién nacido. En el presente artículo se reporta un caso clínico de una recién nacida de 28 d¡as que acude a la Clínica de Odontopediatría de la Universidad Peruana Cayetano Heredia con el motivo de consulta que el infante presenta dos piezas dentarías desde el nacimiento.

Natal teeth are those teeth present in the oral cavity at the time of birth and can generate a lingual ulcer called Riga-Frede Disease interfering with the infant feeding. This article reports a case of a newborn of 28 days who arrived to the Pediatric Dentist Clinic of the Universidad Peruana Cayetano Heredia with the complaint that the infant has difficulty breastfeeding and has two teeth from birth.

Natal teeth: a sign of fortuity or grave misfortune.

Natal teeth are defined as those present in the mouth at birth. They are uncommon and most frequently occur in the anterior mandible as a pair of primary incisors. They are usually small and poorly developed with little or no root formation. Only 10% of these teeth are supernumerary. Problems arising are difficulty suckling, severe ulceration of the child's tongue or the mother's breast and the risk of aspiration. These situations would warrant extraction. If the natal teeth are firm and asymptomatic, conservative management is indicated. Negative cultural attitudes towards natal teeth demand good parental counselling and vigilant management in relation to child protection.

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.

Dientes natales: revisión bibliográfica y caso clínico / Natal teeth: case report and review

Los dientes natales y neonatales deben valorarse con mucho cuidado; estimando su movilidad, integridad y la presencia de una úlcera (Riga Fede) en la superficie ventral de la lengua causada por su roce con el diente. Los dientes natales podrían parecerse a la dentición temporal normal en tamaño y forma, sin embargo, también pueden presentarse más pequeños, cónicos, con esmalte y dentina hipoplásicos, con poca formación o ausencia de sus raíces. La mayoría de estos dientes no son supernumerarios y no se requieren extracciones en todos los casos. Es de fundamental importancia el seguimiento periódico de un odontopediatra. En este artículo se presenta un caso clínico y se revisa la epidemiología, etiología, presentación clínica, diagnóstico diferencial, así como, el manejo de los dientes natales.

Natal and neonatal teeth should be evaluated carefully, considering their mobility, integrity and the presence of an ulcer (Riga Fede) on the ventral surface of the tongue caused by his brush with the tooth. Natal teeth may resemble normal primary dentition in size and shape, however, may also smaller, conical, with hypoplasic enamel and dentin, with little development or absence from their roots. Most of these teeth are not temporary and does not require removal in all cases. It is essential periodic monitoring of a pediatric dentist. This article presents a case report and review the epidemiology, etiology, clinical presentation, differential diagnosis and the management of natal teeth.

Natal primary molar: clinical and histological aspects.

The authors report a case of natal primary molar in a healthy 14-day-old child. The diagnosis of the case and the treatment plan are discussed, as well as histological analyses of the natal tooth. The tooth presented an immature appearance, with high mobility and insertion only in soft tissue, and therefore the clinical option adopted was dental extraction. Histological analyses revealed enamel hypoplasia and dentin showing a typical tubular pattern without alterations. The soft tissue had young and richly vascularized pulp with areas of chronic inflammatory infiltration.

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.

[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.

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 teeth: apropos of five cases]. / Dents natales: à propos de cinq cas.

INTRODUCTION: The normal eruption of primary teeth begins with mandibular incisors about the age of 6 months. There are several qualifiers used to describe prematurely erupted teeth. Massler and Savara defined "natal teeth" as teeth present at birth and "neonatal teeth" as teeth erupted within the first month of life. The aim of this study, based on 5 cases, is to present clinical and structural characteristics, etiology, management techniques, complications and a review of the literature for natal teeth. MATERIAL AND METHODS: Our study is a retrospective study of 17,000 infants who were examined in the Neonatal Department of Children Hospital between 1984 and 2001. The material consisted of 5 infants with natal teeth, identified by the pediatrician. We analyzed the family history, the pregnancy history, the gender, the etiology, the complete examination of the infant, the clinical, the structural characteristics, the complications and the management of the teeth. RESULTS: We found 4 boys and 1 girl, 2 of the newborns were premature, all of them observed to have natal teeth. The incidence was 1: 3,400 births. There were 14 natal teeth, 10 incisors (70%) and 4 canines (30%), no molar was found. Nine of the teeth (6 incisors and 3 canines) were maxillary (65%) and 5 (4 incisors and 1 canine) were mandibular (35%). No morphological syndrome was discovered. Most of the teeth were mobile in all directions and were extracted because of the possibility of aspiration, the difficulty in feeding and the ulceration of the ventral surface of the tongue. DISCUSSION: According to the literature, this phenomenon is rare and the incisors are the teeth most commonly involved. Natal teeth are more common than neonatal teeth and nearly 90% of these teeth are the normal primary teeth. The presence of natal teeth is due to several factors related to an unknown cause of disturbed biological chronology. There is no conclusive evidence of a correlation between early eruption and systemic disorders, but some investigators suggest that natal teeth may be associated with certain syndromes. We must keep in mind that radiographic examination is essential for the differential diagnosis between supernumerary and normal primary teeth. The supernumerary teeth should always be extracted but the decision to extract a normal mature natal tooth should be done according to scientific knowledge, mobility of the tooth, local or general complications and parental opinion.

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.
