          Abstract

          The presence of teeth at birth or within a month post-delivery is a rare condition. A newborn, a 2 days old female, with two mandibular incisor natal teeth was examined. The teeth were mobile and were extracted because of the fear of aspiration and refusal to feed. The purpose of this report is to review the literature related to natal teeth epidemiology and discuss their possible etiology and treatment.

          Natal and neonatal teeth in relation to environmental toxicants.

          Infants born to mothers heavily exposed to polychlorinated biphenyls (PCBs) and dibenzofurans (PCDFs) have earlier been reported to have increased prevalences of natal and neonatal teeth. Some tendency toward higher prevalence figures of natal and neonatal teeth can be seen in the literature in normal child populations during the last 40 y. We therefore decided to determine the present prevalence of these teeth in a Finnish population and to evaluate whether infants with natal and neonatal teeth are more exposed to PCBs, PCDFs, and polychlorinated dibenzo-p-dioxins (PCDDs) than infants on average. A total of 34,457 infants born in 1997-2000 in four hospitals in southern Finland were examined for natal and neonatal teeth. The exposure of the infant to PCBs and PCDD/Fs was evaluated by measuring the levels of 17 most toxic PCDD/F and 36 PCB congeners in his or her mother's milk sample when the child was 4-8 wk old. A total of 34 infants had one or two natal (29 infants) or neonatal teeth (five infants). The milk analyses showed that the median level of PCDD/Fs as toxic equivalent (World Health Organization-recommended 2,3,7,8-tetrachlorodibenzo-p-dioxin equivalent quantity for PCDD/Fs in fat) was 11.9 pg/g in fat, and that of PCBs (World Health Organization-recommended 2,3,7,8-tetrachlorodibenzo-p-dioxin equivalent quantity for PCBs) was 7.24 pg/g in fat. These levels corresponded to the prevailing levels. The results showed that the prevalence of natal and neonatal teeth was 1:1000. No association was found between pollutant levels and occurrence of natal and neonatal teeth, indicating that the prevailing levels of PCDD/Fs and PCBs are likely to be below the threshold to cause perinatal eruption of teeth.

            Clinical and ultrastructural study of natal and neonatal teeth.

            The present study was undertaken to evaluate the surface topography of mandibular natal and neonatal incisors at the ultrastructural level using the scanning electron microscope (SEM). The enamel of the teeth exhibited hypoplastic, depressed areas and the incisal edge of natal tooth lacked enamel. In addition, root formation of the teeth was not completed, which correlated with findings that teeth may erupt without root formation.

              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.
