Occulocerebrocutaneous syndrome is a rare condition characterized by orbital cysts and skin tags. The presence of supernumerary teeth has not previously been associated with this syndrome. A primary supernumerary tooth with a permanent supernumerary successor was found in this case. This highlights the importance of very careful examination when assessing children with syndromes.

The prevalence of supernumerary and congenitally missing primary teeth was studied in a sample of 1141 children aged 3-4 years. The prevalence of supernumerary teeth was 0.4%; all the supernumerary teeth being located in the maxillary incisor area. The prevalence of congenitally missing teeth was 0.9%; seven of the missing teeth being maxillary and four mandibular lateral incisors. The differences in the prevalence of the anomalies between the sexes were not statistically significant. Of the fifteen children with a numerical variation of primary teeth, four developed similar anomalies in the permanent dentition.
The aim of this study was to determine the prevalence of hypodontia, hyperodontia, and double formation of primary teeth in Icelandic children in the dental stage DS 02 (primary dentition complete). The study group comprised 927 children (498 boys and 429 girls). This was about 9% of all children aged 0-83 months in Reykjavik at the time of the registration of these anomalies, during the winter of 1978-1979. The children included those presenting for regular examinations in two health centers, children from three kindergartens, and seven pre-school classes from two schools in Reykjavik. Of these children 61.9% were selected for this study as they proved to be in dental stage DS 02 (primary teeth fully erupted). The prevalences were hypodontia, 0.5%; hyperodontia, 0.5%; and double formation, 0.7%. Comparison was made with earlier results from Iceland and with results from several other nations.
An eight-year-old girl residing in Bangalore presented with a complaint of retained primary maxillary and mandibular incisors. Radiographic examination of the case revealed multiple impacted permanent succedaneous teeth with deficient resorption of primary teeth and multiple impacted supernumerary teeth. Family history revealed that the mother also exhibited multiple impacted supernumerary teeth. Based on the clinical presentation, radiographic examination and histopathological studies, this paper discusses the differential diagnosis and management of such a case.
Impaction of primary teeth is very rare especially in the maxillary anterior teeth. A four-year-old male child with the complaint of delayed eruption of right maxillary primary cuspid due to the presence of odontoma is presented.
This report is a clinical case of a 7-year-old child who presented right impacted second primary mandibular molar. This tooth was positioned inferior to the second premolar successor and a supernumerary tooth superior to the second premolar. Clinical examination did not reveal systemic diseases ot trauma in the facial region. Treatment consisted of the extraction of the impacted second primary molar and the supernumerary tooth. Periodic examination was indicated for follow-up.
PURPOSE: This study was designed to assess the sequelae and prognosis of intruded primary incisors. METHODS: Of 196 children who visited the emergency clinic due to intrusion of 310 maxillary primary incisors, 110 children (172 teeth) were available for follow-up examination (study group). Eighty-six children (138 teeth) did not show for the follow-up examination (non-respondents group). Male/female ratio was 1.7:1. Age range of children at time of injury was 12-72 months (mean 28). Follow-up time ranged between 0 and 59 months (mean 27). RESULTS: Fifty-seven percent of all teeth were completely intruded. In 80%, the root was pushed labially. All but two ankylosed teeth re-erupted, and 37% of these re-erupted into an ectopic position. Completely intruded incisors re-erupted into an ectopic position in a higher percentage (45%) than partially intruded teeth (30%). Fifty-two percent of the teeth presented pulp canal obliteration (PCO). Sixty-four percent of the completely intruded incisors presented PCO compared to 40% of partially intruded teeth. Arrest of dentin apposition was found in 15% of the teeth, and was not affected by the degree of intrusion. Twenty-three teeth were extracted shortly after the injury due to suspect of contact with the developing permanent successor (19 teeth) and severe caries (4 teeth). Sixty-eight percent of the intruded teeth survived more than 36 months after the injury. Twenty-three percent were extracted due to periodontal breakdown and 5% due to repeated trauma. Antibiotic therapy did not have any effect on the survival rate. CONCLUSION: The majority of intruded primary incisors may re-erupt and survive with no complications after more than 36 months post trauma even in cases of complete intrusion and fracture of the labial bone plate.
The purpose of this study was to report in a 12-year old white child a rare clinical condition called regional odontodysplasia. The diagnosis was based on clinical and radiographic findings. Due to the patient's concern over appearance, the treatment involved extracting the affected teeth and subsequently placing partial removable prostheses, thus providing the patient better function and appearance. The teeth that were removed were examined histologically, both in routine preparation stained by hematoxyline and eosin, and in ground sections.

Supernumerary teeth are among the most significant dental anomalies affecting the primary and the permanent dentitions. Mesiodens is a supernumerary tooth with a cone shaped crown and a short root. Though it occurs frequently in the permanent dentition, it is extremely rare in the primary dentition. The exact etiology is still obscure and not well understood. Supernumerary teeth occur as isolated dental findings or as part of a syndrome. The frequency with which supernumerary teeth occur and the effects they have on development of normal occlusion justify the radiographic examination of preschool children. Early removal of such teeth is recommended if they impede the eruption of adjacent permanent teeth, appear inverted or rudimentary, associated with certain pathologic conditions or are symptomatic.
Compound composite odontoma, is a tumor formed by the overgrowth of transitory or complete dental tissue, made up of one or more rudimentary teeth. Although odontomes are considered to be quite common of odontogenic tumors, these rarely occur solely in primary dentition. This paper is a report of case of a compound composite odontoma, five year old child who presented to the Department of Pedodontics and preventive Dentistry, College of Dental Surgery, Manipal.

The purpose of this paper is to report the occurrence of odontogenic keratocysts in a young child. Odontogenic keratocysts are one of the principal features of nevoid basal cell carcinoma syndrome. Their occurrence in this syndrome is usually during the second or third decades of life. This report describes the occurrence of odontogenic keratocysts in a 5-year-old, which proved to be the initial presentation of nevoid basal cell carcinoma syndrome and highlights the need to consider this syndrome as a possible diagnosis in all cases of odontogenic keratocysts.
