Prevalence of dental fluorosis in children from non-water-fluoridated Halmstad, Sweden: fluoride toothpaste use in infancy.

OBJECTIVES: To determine the prevalence and severity of dental fluorosis in children aged 7-9 years from non-water-fluoridated Halmstad, Sweden, and to relate the results to their reported fluoride exposure history during infancy. MATERIAL AND METHODS: In Spring 2002, a questionnaire distributed to a cluster random sample of 1039 parents enquired into their child's early oral health behaviors and included a "photographic toothpaste menu". The permanent upper anterior teeth (13-23) were examined clinically (+10% repeats) using a modified Thylstrup-Fejerskov Index. RESULTS: Complete data were available for 53% (n=548) of the sampled children. The prevalence offluorosis at any level was 49% (95% CI: 45-54%), and of fluorosis with esthetic concern (TF score > or =3) 4% (95% CI: 3-6%). Based on repeat observations, reliability was good (kappa = 0.82). There was no statistically significant increased risk of dental fluorosis prevalence associated with any of the fluoride exposure risk factors examined, including reported usage of (1000 ppm) fluoride toothpaste from time of first deciduous tooth eruption. CONCLUSIONS: While there were low levels of dental fluorosis of esthetic concern, half the children had some degree of dental fluorosis. The prevalence of dental fluorosis was not explained by the risk factors, including fluoride toothpaste usage as explored in this study.

Cleidocranial dysplasia: diagnostic criteria and combined treatment.

Cleidocranial dysplasia (CCD) is an uncommon, generalized skeletal disorder characterized by delayed ossification of the skull, aplastic or hypoplastic clavicles, and serious, complex dental abnormalities. There are many difficulties in the early diagnosis of CCD because a majority of the craniofacial abnormalities becomes obvious only during adolescence. In the present case, a hypoplastic midface, a relative prognathia of the mandible, and close approximation of the shoulders in the anterior plane were the conspicuous extraoral findings. Prolonged exfoliation of the primary dentition, unerupted supernumerary teeth, and the irregularly and partially erupted secondary dentition produced occlusional anomalies. The presence of the second permanent molars together with the primary dentition and wide spacing in the lower incisor area were typical dental signs. Gradual extraction of the supernumerary teeth and over-retained primary teeth was the first step of oral surgery. This was followed by a surgical exposure of the unerupted teeth by thinning of the cortical bone. Orthodontic treatment was aimed at parallel growth of the jaws. Removable appliances were used to expand the narrow maxillary and mandibular arches, and a Delaire mask compensated for the lack of sagittal growth of the upper jaw. Temporary functional rehabilitation was solved by partial denture. When the jaws have been fully developed, implant insertions and bridges are the therapeutic measures. The reported case and the literature data support the importance of the early diagnosis and interdisciplinary treatment of CCD.

Compound odontomes associated with impacted maxillary primary central incisors: report of two cases.

Odontomes associated with primary teeth are rare. This report describes two cases of compound odontome associated with impacted maxillary primary central incisors in patients aged 1 year 8 months and 1 year 2 months, the latter being the youngest to have been reported with the condition. The odontomes were removed under local anaesthesia. Histological examination revealed immature dental tissues in both cases, but no evidence of root formation. Case 1 revealed 'ghost cells' within the enamel epithelium. The impacted incisors erupted following removal of the odontomes; in Case 2 the crown had an unusual ridge on its labial surface, extending from the gingival margin to a few millimetres from the incisal edge.

Dental complications associated with repeated orotracheal intubation in infancy: a case report.

Various oral and dental problems have been attributed to orotracheal intubation in the neonatal period. A case is described of a child whose dental anomalies are ascribed to multiple orotracheal intubations for the management of a complex cardiac abnormality. Six intubations were required between the ages of 9 days and 4 years for investigation and surgery. His maxillary right primary central incisor did not erupt until 3 years of age and the maxillary left was still unerupted at 6 years and 10 months and was rotated in its crypt. At this time, the mandibular primary incisors were physiologically mobile but the maxillary right primary central incisor remained firm. Both maxillary primary central incisors were extracted and examined histologically and showed abnormal morphology, enamel hypoplasia, and disordered dentine formation and root resorption. Subsequent eruption of the left permanent central incisor revealed hypoplasia of its incisal edge. It is suggested that the delayed eruption and abnormal morphology of the primary incisors were due to pressure effects on the overlying mucosa, follicular displacement and localized trauma caused by intubation. This case highlights the importance of monitoring the developing dentition of patients with a history of orotracheal intubation, so that interceptive treatment may be instituted when appropriate.

Treatment of vital and non-vital primary molar teeth by one-stage formocresol pulpotomy: clinical success and effect upon age at exfoliation.

The clinical success and effect upon the age at which teeth exfoliated was prospectively observed in 175 primary molars that had received formoceresol pulpotomies performed by one operator. The success rate among 142 vital teeth was 99.3% and among 33 non-vital teeth 84.8%. There was no significant effect upon age at exfoliation after either type of pulpal treatment.

Infraocclusion of primary molars in monozygotic twins: report of two cases.

Genetic factors have been implicated in the aetiology of infraocclusion, but only three published reports describe infraocclusion of primary molars in twins. This case report describes the occurrence of infraocclusion in two pairs of twins. The distribution of affected teeth and the severity of infraocclusion were strikingly similar in each pair. The report provides further evidence of a genetic contribution to the aetiology of the condition, and also highlights the need to examine siblings, and especially twins, of children who present with an infraoccluded primary tooth.

Eruption disturbances of maxillary permanent central incisors associated with anomalous adjacent permanent lateral incisors.

Several causes of eruption disturbances in upper permanent central incisors have been described. This report describes six cases in which the failure of maxillary permanent central incisors to erupt appears to be associated with developmental anomalies in the adjacent permanent lateral incisors. The root formation of the unerupted central incisors was delayed in comparison to the contralateral incisors as was the development of the adjacent lateral incisors. The shapes of the crowns were abnormal and in five cases out of the six described, the primary predecessors of the unerupted incisors were fused.

Variations in expression of oral-facial-digital syndrome (type I): report of two cases.

Two case reports are presented, both clearly demonstrating the diagnosis of oral-facial-digital syndrome, type I, but widely different in the expression of the condition. The first patient showed only mild expression of the syndrome. On examination at the age of 4 years there were no obvious extra oral signs, intraoral findings included the presence of supernumeraries in the primary dentition, spacing in two areas and the presence of an extra frenum. The second can be considered as a more severe case. This patient had many of the typical manifestations, including frontal bossing, a degree of zygomatic hypoplasia and clinodactyly. Orally, the most striking finding was a bilateral cleft palate which had not been diagnosed prior to examination at the age of 6 years. Other findings included multiple frena and a bifid tongue.

Missing C, supplemental D and supplemental premolar all in one quadrant: a case report.

This case report describes a non-syndromic Caucasian patient who presented with a missing upper right primary canine and a supplemental upper right primary first molar. Later, a supplemental premolar developed in the upper right quadrant. The report highlights the importance of early diagnosis of dental anomalies and a multidisciplinary approach to treatment planning. A regular review and radiographic examination are essential.

Talon cusp in a primary lateral incisor from a medieval child.

This paper describes talon cusp in an ancient skeleton and is a rare report of its occurrence in a primary lateral incisor. As well as talon cusp, the affected incisor also shows abnormal widening, probably representing a double tooth. There is also a supernumerary permanent incisor. The report shows that talon cusp existed in British populations more than 600 years before the first written description. A brief review of the literature on the occurrence of talon cusp in the primary dentition is presented.

Restoration of severely decayed primary incisors using indirect composite resin restoration technique.

Caries of primary incisors is a common problem in paediatric dentistry in some countries. The restoration of primary incisors which have been severely damaged by early childhood caries or trauma is also a difficult challenge for clinicians. This case report describes an indirect technique for the restoration of primary anterior teeth using composite resin reinforced with a fibre-glass post. Over a one-year period, the crowns have demonstrated good retention and aesthetic results. The restorations were provided in two short chair-side sections, with satisfactory patient cooperation.

Gingival fibromatosis and significant tooth eruption delay in an 11-year-old male: a 30-month follow-up.

This case report describes the dental management of an unusual case of idiopathic gingival fibromatosis with multiple impacted primary teeth, and the absence of eruption of permanent teeth, in an 11-year-old boy and at the 30-month follow-up. The patient presented with severely enlarged gingival tissues affecting both arches and multiple retained and non-erupted primary teeth. He had already been subjected to localized gingivectomies at the ages of 7 and 9 years. He had no known syndrome and there was no family history of any similar disorder. The patient was treated under general anaesthesia to remove the excessive gingival tissues using apically positioned flaps. During the surgical procedure, over-retained and unerupted impacted primary teeth were extracted in order to facilitate the eruption of the permanent successors. Two years postoperatively, there was no recurrence of the gingival enlargement. Overdentures were then constructed because none of the permanent teeth had yet erupted. Furthermore, pre-eruptive coronal resorption was detected radiographically affecting the crown of the unerupted 36. Thirty months postoperatively, no recurrence of gingival enlargement was seen, but the permanent teeth had still not erupted.

An unusual distribution of supplemental teeth in the primary dentition.

Supernumerary teeth are more common in the permanent than the primary dentition. In the latter, the majority occur in the maxillary lateral incisor region or as a mesiodens. Indeed, in one study conducted in the USA, all 26 cases of primary supernumerary teeth examined were found to be lateral incisors. This report describes a case presenting with three erupted supernumerary (supplemental) teeth in the primary dentition, including, somewhat unusually, bilateral duplication of maxillary canines.

Is there life after Buckley's formocresol? Part II - Development of a protocol for the management of extensive caries in the primary molar.

OBJECTIVE: To produce a working clinical protocol for pulp therapy techniques in the extensively carious primary molar. INTRODUCTION: The International Agency for Research on Cancer has recently classified formaldehyde as carcinogenic to human beings. As such, a medicament that can be used to replace formocresol in clinical practice should be identified. METHODS: Part I of this paper explored the currently available alternative interventions and materials to formocresol in the form of a narrative review following an extensive literature search. Part II now presents the formation of a specialist group to establish an evidence-based protocol, for the management of the extensively carious primary molar. CONCLUSION: A protocol and key points document have been developed to assist clinicians in their treatment planning. Areas for further postgraduate training are identified.

Congenitally missing maxillary primary canines: report of three cases.

BACKGROUND: Hypodontia is uncommon in the primary dentition and lateral incisors are the most commonly missing primary teeth in the patients affected. Studies have found that hypodontia in the primary dentition involving only maxillary canine is rare. CASE REPORTS: Three cases of hypodontia in the primary dentition involving only maxillary canine are presented. Two of them were affected by hypodontia and hyperdontia in the permanent dentitions respectively, yet all the permanent canines developed normally in these three cases. CONCLUSION: In children with congenitally missing maxillary canines, the permanent dentitions may show diverse anomalies in tooth numbers, ranging from hypodontia to hyperdontia.

Is amelogenesis imperfecta an indication for renal examination?

BACKGROUND: The term 'amelogenesis imperfecta' (AI) describes a diverse group of hereditary conditions primarily affecting the quality and/or quantity of dental enamel. CASE REPORT: This paper describes a case in which hypoplastic AI with delayed/failure of eruption of the permanent teeth was shown to be associated with renal calcification. CONCLUSION: Given the importance of the renal involvement, the authors suggest that paediatric dentists consider referring all children with this dental phenotype for renal ultrasound examination.

A longitudinal study of early childhood caries in 9- to 18-month-old Thai infants.

OBJECTIVE: To examine the rate and pattern of early childhood caries (ECC) development and to investigate the transitional changes of the carious lesions during a follow-up period of 3-9 months. METHODS: A longitudinal observational community-based survey of 599 children, 9-18 months old. The children's dental examinations were first carried out at the age of 9 months with re-examination at 12 and 18 months by five dentists using standardized methods. The affected rates of dental caries were determined for prevalence, incidence density for risk of caries per person (IDp) and risk by surface (IDs). Changes in dental status over time were explored from unerupted (U) to sound (S), including enamel caries (D1), dentine caries (D2) and caries involving pulp (D3) by computing transitional probabilities. RESULTS: The prevalence of caries was 2.0%, 22.8% and 68.1% among 9-, 12- and 18-month olds, respectively. The IDp observed for newly affected children 9-12 and 12-18 months old was 10.32 and 15.70 persons/100 person-months, respectively. The IDs for children 9-12 months old was 2.17 newly affected surfaces/100 surface-months whereas it was 2.22 surfaces/100 surface-months for children 12-18 months old. The buccal surface of maxillary incisors was the most affected (44.9%) followed by lingual, mesial and distal surfaces, respectively. The transitional probability of caries progression ranged between 1.79% and 15.38% during the follow-up period from 9 to 12 months old. It was 3.43-39.60% from 12 to 18 months old. CONCLUSIONS: An extremely high caries-affected rate was found among the study children even before the age of 18 months. The buccal surface of the maxillary incisors was the most affected. The teeth acquired caries at 3-6 months after initial eruption and carious lesions developed continuously over time.
