Tooth eruption symptoms: a survey of parents and health professionals.

UNLABELLED: It is commonly believed that teething in infants can cause a variety of signs and symptoms. Previous studies have suggested an association between teething and fever, irritability, drooling, rashes, vomiting, diarrhea, night crying, and convulsions. PURPOSE: The objective of this study was to evaluate differences in the beliefs of pediatricians, pediatric dentists and parents regarding symptoms caused by teething in infants. METHODS: A survey consisting of demographic information and questions concerning commonly reported symptoms associated with teething was administered to 100 randomly selected Iowa pediatricians, all practicing pediatric dentists in Iowa (n = 33) and a convenience sample of 120 parents from the greater Iowa City area. Responses were analyzed using the Chi-square test. RESULTS: Response rates for each group were: pediatricians 45%; pediatric dentists 76%; and parents 50%. The majority of individuals in each group believed that teething in infants can cause swollen gums, drooling, irritability, inflamed gums, restlessness, sleeplessness, and fever. There were significant differences in the percent of agreement relating to drooling (p = 0.001), inflamed gums (p = 0.001), and sleeplessness (p = 0.027). A greater percentage of pediatric dentists and parents agreed that these symptoms were caused by teething than did pediatricians. The largest difference between groups was related to the association between teething and diarrhea. The majority of parents (56.7%) and pediatric dentists (52.0%) believed that diarrhea is associated with teething compared to just 9.1% of pediatricians. CONCLUSIONS: These results support the hypothesis that differences regarding beliefs about teething symptoms exist between parents, pediatricians, and pediatric dentists. There is more agreement between parents and pediatric dentists than between either of these groups and pediatricians.

[Guidance of tooth eruption in the support areas using proximal grinding].

This article brings a description of a procedure for interproximal slicing. When persistence of the second deciduous molar occurs, the premolar is likely to be blocked in his eruption, while the canine is guided out of the dental arch; in these conditions it might be necessary to perform a slicing mesially of the second deciduous molar. Beforehand one should check for the posterior tooth-size and eruption pattern or sequence of each quadrant.

Neuroendocrine alterations impair enamel mineralization, tooth eruption and saliva in rats.

Neonatal administration of monosodium glutamate (MSG) in rats causes definite neuroendocrine disturbances which lead to alterations in many organ systems. The possibility that MSG could affect tooth and salivary gland physiology was examined in this paper. Male and female pups were injected subcutaneously with MSG (4 mg/g BW) once a day at the 2nd, 4th, 6th, 8th and 10th day after birth. Control animals were injected with saline, following the same schedule. Lower incisor eruption was determined between the 4th and the 10th postnatal days, and the eruption rate was measured between the 43rd and the 67th days of age. Pilocarpine-stimulated salivary flow was measured at 3 months of age; protein and amylase contents were thereby determined. The animals treated with MSG showed significant reductions in the salivary flow (males, -27%; females, -40%) and in the weight of submandibular glands (about -12%). Body weight reduction was only about 7% for males, and did not vary in females. Saliva of MSG-treated rats had increased concentrations of total proteins and amylase activity. The eruption of lower incisors occurred earlier in MSG-treated rats than in the control group, but on the other hand the eruption rate was significantly slowed down. The incisor microhardness was found to be lower than that of control rats. Our results show that neonatal MSG treatment causes well-defined oral disturbances in adulthood in rats, including salivary flow reduction, which coexisted with unaltered protein synthesis, and disturbances of dental mineralization and eruption. These data support the view that some MSG-sensitive hypothalamic nuclei have an important modulatory effect on the factors which determine caries susceptibility.

Continuing tooth eruption and alveolar crest height in an eighteenth-century population from Spitalfields, east London.

Earlier studies on dried skulls have shown that continuing eruption occurs throughout life to an extent which appears to compensate for occlusal attrition. Some investigators have interpreted the increasing distance between the tooth cervical margin and the alveolar crest as an indication of horizontal bone loss due to chronic inflammatory periodontal disease. In order to determine whether continuing eruption occurs in the absence of attrition, measurements were made on the jaws of an eighteenth-century population whose tooth wear had been minimal. Horizontal bone loss at the alveolar margin was minimal or absent. Continuing eruption had occurred, indicating that facial height probably increased throughout the life time of the individuals.

Mandibular cheek tooth eruption and development in Hereford cross Friesian steers as a means of age determination.

The development of the mandibular cheek teeth was examined, both visually and by radiograph, in a group of 76 Hereford cross Friesian steers, of which all but one were slaughtered at the same weight - 464 kg (1020lb). The age of the youngest animal was 1 year 0.3 months whereas the slaughter ages of the others ranged from 1 year 3 months to 1 year 8 months. The first molar was fully erupted and crown and root formation complete in all but the youngest steer. In the other five cheek teeth there were one or more significant differences between the mean ages of tooth development stages as assessed by radiograph. Cattle of 1 year 3 months could not be absolutely distinguished from those of 1 year 8 months by intra-oral second molar eruption. Examination of stages of development seen radiographically gave a maximum age range of 4 months before differentiation. In this study, development of the first two molars was in advance of the three permanent premolars and in these latter teeth the second premolar was the most developed.

Root resorption of a partially erupted tooth: a case report.

This article reports a case of a maxillary second premolar which on presentation was partially erupted, and which resisted attempts at orthodontic extrusion. The crown of the tooth was eventually restored using an adhesive composite onlay technique. The patient subsequently complained of pain and the root of the tooth showed radiographic evidence of resorption. The root of the extracted tooth had a vital pulp but massive external resorption was evident, with repair with bone-like material.

Dental abnormalities associated with failure of tooth eruption in src knockout and op/op mice.

c-src knockout and op/op mice develop osteopetrosis as a result of defective osteoclast function and osteoclast formation, respectively. The mutant mice can be distinguished readily from their wild-type littermates around 10-12 days after birth because their incisors do not erupt, but the morphology of their teeth and surrounding bone has not been reported previously in detail. Histologic examination of jaws of src-mutant mice reveals unerupted, abnormal incisors within their bony crypts. The tooth roots are distorted by foci of haphazard proliferation of odontogenic epithelium associated with primitive tooth structures that strongly resemble the tumor-like lesions in humans, known as odontomas. The crowns of the incisors are fused to the adjacent bone, and the developing periodontal ligament is disordered and hypocellular. Osteoclasts are present in the bone surrounding the distorted teeth, but as in other bones in these mice they lack ruffled borders and thus do not resorb effectively. Similar odontogenic proliferation is present around unerupted incisors in op/op mice which form very few osteoclasts, but the amount is significantly less than in src mutant mice. Molars fail to erupt in both types of mutant mice, but they are not accompanied by aberrant odontogenic proliferation. These findings and previous reports of similar abnormalities in jaws from op/op rats suggest that failure of incisor eruption and associated proliferation of odontogenic epithelium in osteopetrotic rodents are a direct result of defective osteoclastic bone resorption.

Mucopolysaccharidosis: MPS VI and associated delayed tooth eruption.

Eight cases of mucopolysaccharidosis Type VI (Maroteaux-Lamy syndrome) are reviewed and two cases are presented in detail. Developmental dental anomalies including unerupted and impacted permanent teeth and associated hyperplastic tooth follicles are seen frequently in MPS patients. The surgical implications and management are discussed. All patients reviewed had significant cardiovalvular disease. It is essential for the primary medical provider to establish early basic dental care and evaluation for delayed eruption of primary and permanent dentition. This will probably minimize the possibility of infective endocarditis and allow for early treatment of impacted teeth.
