Dental anomalies in children with cleft lip and palate in Western Australia

Abstract

Objective:The purpose of this paper was to describe the prevalence and type of dental anomalies in the primary and permanent dentition in children with a cleft condition at Princess Margaret Hospital in Perth, Western Australia.Materials and Methods:The details of 162 current dental patients extracted from the main dental database through their year of birth for the period 1998–2001 were selected consecutively. Dental records and X-rays were examined by one examiner (WN) and verified by a second examiner (RB) to determine dental development. The mean age of the subjects was 10.8 years with equal numbers of males and females. Subjects were further divided into cleft type; unilateral cleft lip (UCL) and palate, bilateral cleft lip (BCL) and palate, UCL, BCL, and cleft palate.Results:One hundred sixty-two subjects were grouped into 21 categories of anomaly or abnormality. Prevalence rates for the categories were calculated for the overall group and for gender and cleft type.Conclusion:Overall, 94% of patients were found to have at least one dental anomaly, with fifty-six (34%) patients having more than one anomaly or abnormality.

Investigation of prevalence of dental anomalies by using digital panoramic radiographs

“…The congenital types are inherited and have a genetic basis, the developmental types arise during tooth improvement, and the acquired anomalies arise after tooth improvement [25]. Dental anomalies may occur due to various factors, including environmental and genetic influences [20]. Developmental anomalies are events that happen during the tooth developmental processes and can range from simple isolated defects to symptoms of specific syndromes [13,18].…”

“…About 94% of cleft patients have at least one dental anomaly [2] and can present with one or more of the following features:…”

Anomalías dentales de los pacientes con labio y paladar hendido

“…En Australia se evidenció que la prevalencia fue de 63 % siendo más frecuente en hombres (43). Otro estudio en Colombia reportó que el 43,3 % de los pacientes tenían al menos un diente supernumerario (33).…”

“…principalmente el diente incisivo lateral. Ninguna de las anomalías de forma mostró dimorfismo sexual significativo (43).…”

“…En un estudio con 178 pacientes en Brasil se encontró giroversión en el 20 % (40). En una investigación en Suecia se evaluaron 129 pacientes, el 55 % de ellos presentaron rotación dental del diente incisivo central superior (27); y en Australia, de 162 pacientes examinados, el 60 % presentaron rotación dental, siendo más prevalente en hombres (43). Esta desviación posicional estaba asociada a la falta del incisivo lateral en la premaxila (27) y con menos frecuencia se reportan transposición y dientes ectópicos 30,8 % (26).…”
