Richard III -- the final act.

On 4 February 2013 experts confirmed that the remains of the last English king to die in battle were found under a council car park in Leicester, England. Richard III, the last Plantagenet king, wore the crown from 1483 until his untimely death in 1485. There have been many myths published about him, even one with a dental reference. This paper explores what dentistry was like at the time of Richard III, reveals the truth behind the myths and sees how the University of Leicester's findings about his dentition and skull has provided an insight into his identification, lifestyle and final moments.

Natal and neonatal teeth: a systematic review of prevalence and management.

AIM: The purpose of this systematic review was to identify and review the literature concerning natal and neonatal teeth. STUDY DESIGN AND METHODS: The literature search was conducted using several databases. Specific terms were used in the search, which includes articles from 1950 to 2011, supplementary searching by hand was also used. Relevant studies were selected according to predetermined inclusion criteria. RESULTS: Studies meeting the inclusion criteria were only found with regards to prevalence and management of natal and neonatal teeth. Prevalence ranged from near 0 to 1:10 while extraction or maintenance of teeth comprised the management options. CONCLUSION: There is significant need for further research, under specific scientific preconditions, to provide an evidence-based treatment for patients and to determine the prevalence of natal and neonatal teeth more precisely.

Attitude and beliefs of some nurses in government hospitals in Ibadan, Nigeria to natal/neonatal teeth in infants.

Eruption of the first deciduous teeth in children has shown much variation and occasionally may erupt prematurely at birth or within one month of life. Myths about natal/neonatal teeth abound in the Nigerian culture. Nurses are health care providers who are in constant close contact with patients and can be invaluable in helping to dispel these associated myths. However, to provide correct information they should be adequately equipped to do so. The aim of this study thus, was to assess the attitudes and beliefs of some nurses in Ibadan, Nigeria to natal/neonatal teeth in infants. A cross sectional survey was conducted among 380 nurses in the teaching, general and local government hospitals and clinics in Ibadan, Nigeria. Results revealed that 41.3% of the respondents would express shock and surprise if they assisted in delivering a baby with natal teeth. Half of the respondents (49.7%) felt that natal/neonatal teeth will be a great source of embarrassment to the family while a smaller proportion (11.8%), believed it was a curse (p = 0.01). On the advice the respondents would give to the mothers, more than a th (39.7%), would recommend immediate extraction of the teeth. A further 42 (11.1%) nurses were of the opinion that spiritual cleansing should be carried out prior to extraction. A greater proportion of the older nurses would advice immediate extraction of the teeth (p = 0.031). Regarding the perceived effect of natal/neonatal teeth on the children, (7.4%), (12.6%) and (29.2%) of the respondents believed that the children will behave strangely, will possess spiritual authority and be victims of stigmatization later in life respectively. This study has revealed that knowledge gaps about natal/neonatal teeth exist among the nurses in Ibadan, Nigeria. Health education programmes targeted at nurses are essential to correct these beliefs.

Posterior neonatal teeth.

Teeth which are present in the oral cavity of newborn infant at the time of birth are called "natal teeth" and which erupts in first month of postnatal life are called as "neonatal teeth." The incidence of these teeth is 1 in 2000 to 1 in 3500 live birth. The most common natal teeth reported are mandibular central incisors followed by maxillary incisors and mandibular canine. The natal or neonatal tooth in maxillary molar region is a rare occurrence. This article represents a rare case of bilateral neonatal maxillary molar teeth.

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.

Severe oligodontia and dental anomalies in a child with a history of multiple natal teeth: An eight-year retrospective.

This article reports the case of a boy born with 11 natal teeth who had many alterations in his permanent dentition. In this case, 22 teeth were missing and a shape anomaly was detected in eight teeth. The treatment consisted of prosthetic rehabilitation and follow-up of teeth eruption and jaw growth.

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.

Size, ultrastructure, and microhardness of natal teeth with agenesis of permanent successors.

OBJECTIVE: Natal and neonatal teeth may occur in conjunction with other oral anomalies, including anomalous development of succedaneous teeth. Our purpose was to examine the size, ultrastructure, and microhardness of two natal teeth without permanent successor germs, and compare them with the characteristics of normal primary teeth. DESIGN: The dimensions of two natal mandibular incisors extracted from a healthy 7-year-old child were measured with a digital sliding caliper. The crown dimensions of normal primary mandibular central incisors were established from dental casts of 102 children. Since the natal teeth were nearly completely devoid of enamel, the average enamel thickness determined on a sample of 19 normal primary mandibular incisors was added to the values measured. External surfaces and transverse sections of the natal teeth were examined under a scanning electron microscope. Vickers microhardness of radicular dentine was assessed for the natal teeth and for 11 normal primary mandibular incisors. RESULTS: Only remnants of enamel were present. All crown dimensions corrected for enamel loss were within the normal range. The ultrastructure of hard dental tissues was normal. The radicular dentine hardness of the natal teeth was similar to that of the normal primary mandibular incisors. CONCLUSIONS: The results indicate that the natal teeth were prematurely erupted regular primary mandibular central incisors. In our case, the occurrence of natal teeth associated with agenesis of their primary successors appears to be related to an accelerated or premature pattern of dental development, rather than to superficial positioning of the tooth germs.

Relaçäo cor da pele/cor dos dentes em pacientes dentados naturais / Study of the relationship between skin color and tooth color in dentate patients

Os autores investigaram a cor dos dentes naturais em pacientes dentados, com o objetivo de observar ser válida ou näo a correlaçäo preconizada entre a cor dos dentes e a cor da pele e dos dentes e a cor da pele e dos cabelos, para a seleçäo da cor dos dentes artificiais das dentaduras. Utilizou-se de 240 pacientes dentados naturais, com idades variando entre 15 e 25 anos, divididos conforme suas características físicas em 6 grupos, como se segue: G1-negros; G2-mulatos; G3-amarelos; G4-brancos de cabelos pretos; G5-brancos de cabelos castanhos e G6-brancos de cabelos louros. Concluíram que a cor da pele e dos cabelos näo é indicador válido para se determinar a cor dos dentes artificiais para dentaduras, caso se queira reproduzir o que ocorre na natureza

Estudo da inclinaçäo das vertentes das cúspides de suporte, em relaçäo ao plano áxio-orbital, em dentes naturais e duas marcas de dentes artificiais utilizados em prótese parcial removível / A study of the inclination of supporting cusp slopes, in relation to the axio-orbital plan, on natural teeth and two brands of artificial teeth utilized in removable partial prosthodontics

Pela técnica da estereometria, foram analisadas, em relaçäo ao plano áxio-orbital, as inclinaçöes das vertentes triturantes distais superiores e mesiais inferiores das cúspides de suporte. Essas vertentes säo as superfícies onde podem ocorrer interferências em balanceio, consideradas entre as mais danosas ao sistema estomatognático. O estudo foi realizado em 5 pacientes com dentes íntegros e oclusäo ideal sem disfunçäo do sistema estomatognático. Foram analisadas 3 situaçöes de dentiçäo para cada paciente, ou seja, a primeira na condiçäo de dentes naturais, a segunda com dentes artificiais Trubyte Biotone 33º, e a terceira, com dentes artificiais Orthosit PE. Dentro das condiçöes experimentais desta pesquisa, chegamos à conclusäo de que, em dentes naturais, as vertentes analisadas apresentam uma semelhança estatística entre si, ou seja, parece existir um paralelismo relativo entre elas. Observou-se, também que näo há correspondência entre as inclinaçöes das vertentes analisadas dos dentes superiores com as suas respectivas vertentes antagônicas inferiores. A inclinaçäo cuspídica dos dentes inferiores foi sempre maior em relaçäo aos superiores, e esse fato ocorreu com maior amplitude nos dentes artificiais. Os dois tipos de dentes artificiais testados näo apresentaram as inclinaçöes das vertentes analisadas, perfeitamente compatíveis com as dos dentes naturais. Entretanto, os dentes Trubyte Biotone com 33º de inclinaçäo cuspídica foram os que mais se aproximaram das inclinaçöes médias dos dentes naturais. Estes, sob aspecto da anatomia oclusal, parecem ser os mais indicados para se utilizar em próteses parciais removíveis

Natal and neonatal teeth: a clinical and histological study.

Nine thousand and six hundred infants delivered in a maternity hospital were examined for the prevalence of natal and neonatal teeth. The prevalence among this group was noted. The teeth were the normal primary incisors that had erupted prematurely. The crown was normal in shape and size with very little root formation. The histological features were that of an immature tooth.

Natal teeth.

I conducted a retrospective study based on record reviews of 50,892 infants born at the Foothills Provincial Hospital, Calgary, Alberta, Canada, from 1967 to 1984 to determine the incidence and possible causes of natal teeth. Fifteen infants were affected, for an incidence rate of one in 3,392 births. The affected teeth were the lower central incisors. The condition was more common in female infants. Two of the affected patients were twins. One patient each had Ellis-van Creveld syndrome, Pierre Robin syndrome, adrenogenital syndrome, cleft palate, and rickets. One mother each had pernicious anemia, vaginal infection, and diabetes mellitus.

Natal and neonatal teeth: a clinical study.

In a survey of 18,155 infants, 7,155 of whom were examined personally, the prevalence of natal teeth was one in 716 for the infants examined and one in 3,667 for those surveyed. Another group of 38 infants and children with 61 natal and neonatal teeth were examined prospectively. All were mandibular central incisors. Sixty-one percent of the subjects had a pair of natal or neonatal teeth (or both). Ninety-five percent of the natal and neonatal teeth were normal primary central incisors, and 5% were supernumerary primary central incisors. Initially, in 31% of the teeth, enamel dysplasia was seen, the occurrence of which correlated with the duration of the gingival covering. It is recommended that natal and neonatal teeth be left in place, if possible, and removed only if they are extremely mobile, such that reattachment is unlikely.
