Supernumerary teeth associated with primary and permanent teeth: a case report.

Concomitant presence of a supernumerary tooth in the primary dentition and another supernumerary tooth associated with permanent tooth in the same location is an uncommon condition. Presence of supernumerary tooth in the primary dentition itself is a rare phenomenon. Presented here, is the first such case of simultaneous presence of supernumerary tooth in primary and permanent maxillary lateral incisor region.

Supernumerary teeth in the primary dentition: a report of two cases.

Supernumerary teeth occur frequently in the permanent dentition, but they are rare in the primary dentition. Mesiodens is a supernumerary tooth with a cone shaped crown and a short root. The supernumerary tooth which bears resemblance to the tooth with which it is associated is called a supplemental tooth. The etiology of supernumerary teeth is still unknown and not well understood. Radiographic examination of pre-school children is essential for their diagnosis. Early removal of these teeth is required so that complications such as delay in eruption of permanent teeth, crowding, diastema, rotations and certain pathologic conditions can be averted.

Orthodontic treatment of palatally impacted maxillary canines.

The aim of this study was to determine the feasibility of treating children with impacted maxillary canines by orthodontic treatment alone. The subjects were 28 children (mean age: 13.5 years, range 11.4-16.1 years) with between them 32 palatally impacted canines. The overlying primary canines were extracted between 0 and 42 months before the start of appliance treatment to open space in the arches for the impacted teeth. No other surgical procedures were carried out prior to the start of appliance treatment. Appliance treatment was deferred for at least six months if an impacted canine was the main reason for treatment, otherwise treatment was commenced according to the needs of the patient. In 94% of the cases, the severity of impaction lessened following extraction of the overlying primary canines and orthodontic treatment. The deepest impactions tended to occur in the oldest children. The majority (75%) of the canines emerged following orthodontic treatment to create space for them in the arch; the remainder were surgically exposed. Appliance treatment tended to take longer in children with the deepest impactions. It is concluded that fixed appliance treatment to create space for a palatally impacted canine is an effective management option for children with impacted maxillary canines.

Infraclusion of primary molars: a review and report of a case.

The term infraclusion is usually used to define mandibular primary teeth in posterior region that remain below the occlusion level. The degree of infraclusion depends on some factors like deviation below the occlusal plane, and infraclusion of tooth in the alveolar bone. Deficient eruptive force, disturbed metabolism of the periodontal ligament, trauma, local inflammation, deficient local vertical bone growth, disturbance in interaction between normal resorption and hard tissue repair, ankylosis and hereditary components have been given as etiological factors. Complications of infraclused primary molars are tipping of the neighboring teeth, space loss, supraeruption of the antagonists, and dislocations of permanent teeth lying under the primary tooth. In this case report, after reviewing the literature a patient with infraclused mandibular primary second molar has been examined to observe the complications of infraclusion. With an appropriate treatment approach, a proper condition was prepared for the eruption of permanent teeth.

[The isolation and identification of pathogenic bacteria from rampant caries in children].

OBJECTIVE: In order to prevent rampant caries in children, the predominant pathogenic bacteria of rampant caries in children were defined. METHODS: The pathogenic bacteria of rampant caries were isolated and identified in 30 children with rampant caries, aged from 2 to 5 years old. Samples were collected from the caries of labial surfaces of maxillary anterior deciduous teeth, including caries lesions and caries-free smooth enamel surfaces. Plaque were obtained from the cervical third areas of the maxillary labial anterior deciduous tooth surfaces in children without rampant caries and caries-free children and served as controls respectively. The isolates were identified by colony morphology, biochemical tests and DNA base contents (mol percent G + C). RESULTS: The prevalence of Streptococcus mutans (S. mutans) and Streptococcus sobrinus (S. sobrinus) in the plaque of caries lesions and the proportions of S. mutans and S. sobrinus in the plaque of 2 sampling sites of children with rampant caries were all significantly higher than those of children without rampant caries and caries-free children (P < 0.05). CONCLUSION: S. mutans and S. sobrinus are predominant pathogenic bacteria in rampant caries in children.

Occlusal and oral health status of a group of 3-8-year-old South African black children.

This study determined the oral health status of a group of 3-8-year-old South African black children, comprising a total of 214 children from the townships of Garankuwa, Shosanguwe, Mabopane, Hebron and Erasmus who attended a school in Akasia, Greater Pretoria Metropolitan Substructure. The decayed, missing and filled teeth (dmft), oral hygiene status, dental IQ and malocclusion status were determined. The study found that the children's oral health status and occlusal status were unacceptable. The level of their dental IQ scores was low, their oral hygiene poor, and they were in urgent need of primary and secondary dental care. In addition they were in need of both preventive and interceptive orthodontic care. A national strategy to address primary dental health care is recommended.

Permanent maxillary central incisor impaction: report of two cases.

Impaction of the permanent maxillary central incisor is rare. Trauma to the primary maxillary anterior teeth is the most common cause. Two case reports of impacted permanent maxillary central incisors with a history of trauma to the primary maxillary anterior teeth are presented. In one case there was radiographic evidence of complete arrest of root formation, and in the other case the root was dilacerated from the cervical third and the enamel surface was rough.

Primary molars in severe infraocclusion: a retrospective study.

UNLABELLED: The term severe infraocclusion is used to describe teeth located at the level of or below the alveolar crest and is rare. AIM: The aims of the study were to evaluate the influence of age of diagnosis and treatment on the outcome of the successors of primary molars with severe infraocclusion and to propose a treatment protocol based on the age of diagnosis. METHODS: A retrospective study of patients with primary molars in severe infraocclusion (PMSI) in the period 1987-2001 was carried out. Parameters assessed were age, sex, degree of infraocclusion based on radiographs, altered position of adjacent and successor teeth and treatment outcome. RESULTS: The sample comprised 19 patients with 23 cases of PMSI, all were second primary molars (47.8% maxillary and 52.2% mandibular). Migration of the neighbouring tooth was present in 51.5% of cases. The PMSI treatment was by extraction in all cases, a space maintainer was fitted and remained in place until the eruption of the successor. The outcome was favourable in 82.6% of cases. CONCLUSION: Successful treatment of PMSI depends on prompt diagnosis and appropriate treatment and follow-up of the cases. The earlier the age of detection, the more favourable the outcome.

Reshaping a mesiodens.

A mesiodens is a supernumerary tooth that is found in the midline of the maxilla. Fifteen percent erupt usually between the ages of 3 and 7. The standard treatment is extraction of the supernumerary to allow the permanent incisors to erupt properly. This case report describes an instance where the primary incisor was prematurely exfoliated due to the eruption of the mesiodens. Because of the favorable position of the mesiodens in the dental arch, it was decided to reshape the supernumerary to resemble a primary incisor. This was accomplished successfully, and the mesiodens is being monitored to assess any need to trim or add to the bonding material as the child grows.

[Oral-facial-digital syndrome type I. A case report].

Oral-facial-digital syndrome type I (OFDI) is a congenital X-linked dominant disorder characterized by anomalies of the oral cavity, face and digits sometimes associated to cerebral malformations and polycystic kidney disease. The gene, responsible for this syndrome, is ofd1. Clinically it is seen only in females. Lesions of the mouth include median pseudoclefting of the upper lip, clefts of the palate and tongue, and dental anomalies (missing or supernumerary teeth, enamel hypoplasia, and teeth malpositions). Dysmorphic features affecting the head include hypertelorism, frontal bossing, micrognathia, facial asymmetry and broadened nasal ridge. The digital abnormalities are syndactyly, clinodactyly, brachydactyly and, rarely, pre or post-axial polydactyly. Less frequently ex-pressed phenotypic anomalies include skin milia, alopecia, deafness and trembling. Sometimes the diagnosis of OFDI can be difficult because there is an overlap with other types of oral-facial-digital syndromes. A sporadic case of OFDI, with 7 lower incisors, both in the primary and permanent dentition, is reported. This dental anomaly is very unusual because in literature only supernumerary cuspids are reported. In the light of this case, the authors discuss the oral phenotypic expression of ofd1 gene and its role in human odontogenesis.

Aberrant root formation: review of root genesis and three case reports.

The mechanism of root formation and tooth eruption is a complex process which is not fully understood. Prior to a tooth emerging into the oral cavity, root genesis is initiated by derivatives of the enamel organ. The dental follicle mediates an eruption pathway allowing for movement of the developing tooth in a coronal direction. As the tooth moves towards the oral cavity, root formation occurs passively in the resulting space. Failure of the enamel organ and dental follicle to properly coordinate may result in complications in the eruption process. This clinical report presents 3 cases of isolated, unerupted teeth with dysmorphology of the roots. The process of root development and tooth eruption is also briefly reviewed.

Unerupted mandibular second primary molar with an unusual histopathological finding: a case report.

This is the case of a healthy 6-year old female with a clinically absent right mandibular second primary molar with no history of that tooth ever being present. Radiographic examination revealed a well-circumscribed pericoronal radiolucency surrounding the mandibular right primary second molar. The mandibular right second premolar was displaced mesially. Treatment consisted of enucleation of the lesion with removal of both the unerupted primary second molar and second premolar. The histopathology of the excised lesion revealed a hyperplastic dental follicle with a focal proliferation of odontogenic epithelium and duct-like structures, probably representing an incipient adenomatoid odontogenic tumor.

A European Board of Orthodontics case report. Case category: severe skeletal discrepancy.

OBJECTIVES: this 18.1 year-old girl presented with a chief complaint of progressive worsening of facial and dental esthetics, crowding, headache and facial pain. MATERIALS AND METHODS: clinically, she was at the end of her growth and exhibited a severe facial asymmetry, but with normal sagittal and vertical cranial relationships. Clicking in the right TMJ was evident. This was accompanied by a deviation upon opening, and pain in the joint. The pain she experienced during jaw movement, and upon palpation, was significant. There was a shift to the right from centric relation to intercuspal position. Intraorally, the tissues were normal, with mild tetracycline staining, still present primary canines, impacted third molars and upper permanent canines. Her first molars had fillings. Orthodontically, her occlusion was a severe Class III subdivision left, with a severe right-side crossbite, lower midline deviation to the right 6 mm, and a 1 mm lateral shift in intercuspal position. She also exhibited severe crowding and asymmetry in both arches. The sequence of her treatment was as follows: (a) extraction of primary canines and impacted third molars, surgical exposure of impacted canines, (b) lower occlusal splint for TMJ dysfunction and an upper arch fixed appliance for ideal alignment and leveling, (c) upper occlusal splint for the maintenance of TMJ function and lower arch fixed appliance for ideal alignment and leveling, (d) surgical skeletal correction, (e) post-surgical orthodontic finishing, (f) post-treatment retention.
