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.

Oral abnormalities in Taiwanese newborns.

PURPOSE: The objective of this study was to investigate the frequency of oral abnormalities in newborns in Chang Gung Memorial Hospital, Taipei, Taiwan. METHODS: Study subjects were neonates born at Chang Gung Memorial Hospital between January 2000 and April 2000 (inclusive). All subjects were examined within 3 days of birth. Babies with craniofacial anomalies and/or other systemic diseases requiring intensive care were excluded. A dentist examined newborns using mirrors, tongue blades, and a flashlight. RESULTS: The authors examined a total of 420 neonates and found the frequency to be 94% for oral cysts and 1% for natal and neonatal teeth. Neither the frequency of palatal and gingival cysts of the newborn nor that of natal and neonatal teeth was associated with gender, body weight, and gestation age. CONCLUSIONS: Babies born at Chang Gung Memorial Hospital demonstrate a high rate (94%) of oral cysts of the newborns.

Tooth eruption: theories and facts.

The mechanisms of tooth eruption (i.e., the answer to the question of how and why teeth erupt) has been a matter of long historical debate. This review focuses on human and other mammalian teeth with a time- and spacewise limited period of eruption and analyzes recent observations and experimental data on dogs, rats, primates, and humans in a framework of basic biological parameters to formulate a guiding theory of tooth eruption. Acknowledging basic parameters (i.e., that teeth move in three-dimensional space, erupt with varying speed, and arrive at a functional position that in inheritable) eliminates a number of previously held theories and favors those that accommodate basic parameters, such as alveolar bone remodeling in association with root elongation, with possible correction factors in the form of cementum apposition and periodontal ligament formation. We have critically analyzed, summarized, and integrated recent findings associated with preeruptive movements of developing teeth, the intraosseous stage of premolar eruption in dogs, molar eruption in rodents, and premolar and molar eruption in primates. The variable speeds of eruption are particularly important. We conclude with basic principles of tooth eruption--that is, the type of signals generated by the dental follicle proper, the conditions under which teeth are moved and the clinical understanding to be derived from this knowledge.

Interruption of breast feeding caused by the presence of neonatal teeth.

The authors report the case of a 6-month old girl treated at the Pediatric Dentistry Clinic at the School of Dentistry of the Federal University of Rio de Janeiro. The patient's breast feeding was interrupted prematurely due to the presence of neonatal teeth. The authors have included a brief review of previous reports of this pathology.

Fryns syndrome and erupted teeth in a 24-weeks-old fetus.

We describe a 24-weeks-old fetus with Fryns' syndrome (FS) and two erupted incisors. The present observations is another example of prenatal diagnosis of FS, based on ultrasonographically detected hernia diaphragmatica and cystic hygroma. It also adds an hitherto non described finding in FS. The presence of prenatally erupted teeth without any similar family history is discussed.

Evaluation of primary dentition in cleft lip and palate children with and without natal/neonatal teeth.

OBJECTIVE: Natal/neonatal teeth are very common in children with complete unilateral and bilateral cleft lip and palate. The extraction of these teeth is the usual treatment in the Hospital for Rehabilitation of Craniofacial Anomalies. The objective of this study was to verify whether these teeth could be of the normal complement or whether they were supernumerary. DESIGN: The primary dentition of children with cleft lip and palate with and without natal/neonatal teeth was compared at the Hospital for Rehabilitation of Craniofacial Anomalies. SUBJECTS: The sample consisted of 55 children with complete unilateral and bilateral cleft lip and palate with natal/neonatal teeth and 54 without. RESULTS: No positive association between these groups and missing lateral incisor or supernumerary or complete dentition was found. CONCLUSION: The extraction of the natal/neonatal teeth did not alter the final complement of primary teeth, and these teeth could be the lateral incisor or supernumerary.

A descriptive and comparative study of oral health in 8-year-old Swedish children.

The aim of the study was to assess the oral health of a group of children, and to compare the findings with the results from an investigation performed 4 years earlier in children of the same age and living in the same area. The material consisted of 149 randomly selected 8-year-old children. The study included examination of caries and the state of the gingival conditions, enamel hypoplasia and opacities, supragingival calculus and extrinsic stains. Determinations were also made of the rate of secretion, pH and buffer effect of stimulated saliva. Socio-economic data and anamnestic dental data were noted. The investigation showed a decrease in caries frequency in the primary teeth, but not in the permanent teeth, during the four-year-period. As in the former investigation, regression analyses showed a negative correlation between the level of education of the parents and caries indices, and that the variation of the gingival indices could be explained by socio-economic factors. In addition, a negative correlation was found between the caries index for primary teeth and the rate of secretion of the saliva and the presence of supragingival calculus.

Prematurely erupted deciduous teeth in a Nigerian baby--a case report.

This paper reports the case of a thirteen-day-old male child who was brought to the clinic with lower central incisors which had been erupted into the oral cavity from birth. The teeth, which resembled the normal deciduous series, were mobile. A striking observation was the anxious behaviour of the mother which prompted further probing. History taking revealed that the mother's anxiety was caused by societal unpleasant reaction to her baby's prematurely erupted teeth. The pressure was so intense that she had to seek medical help. At this tender age of the baby, it is advisable to preserve prematurely erupted teeth in order to prevent malocclusion resulting from premature loss of the deciduous teeth. Therefore, it is highly essential that people in this society be enlightened about such cases in order to reduce the psychological stress on parents of children with a similar condition.

Prevalence of natal/neonatal teeth in cleft lip and palate infants.

In the daily routine of the Hospital for Research and Rehabilitation of Cleft Lip and Palate, a high frequency of natal/neonatal teeth was observed. Therefore, this retrospective study was conducted to determine the prevalence of this anomaly in 692 patients with complete unilateral and 327 bilateral cleft lip and palate, who were less than 3 months old, without prior surgery, and registered at the Hospital from 1989 to 1994. A higher prevalence of such teeth was found in the complete bilateral cleft group (10.6%), than in the complete unilateral cleft group (2.02%). Both, however, were higher than that reported for noncleft groups. There were also different characteristics in the appearance of these teeth in cleft patients from those previously related in the literature for normal patients. The conclusion was that these differences constitute another particularity of the cleft lip and palate patient.

Pachyonychia congenita Jackson-Lawler type: a distinct malformation syndrome.

A family with three members in two generations affected by pachyonychia congenita, hyperkeratosis and hyperhidrosis of the palms and soles, follicular keratosis, neonatal teeth and epidermoid cysts (Jackson-Lawler syndrome) is described. The nosological autonomy of this condition is proposed and a further heterogeneity is suggested on the basis of histopathological changes in the subcutaneous cysts.
