Comparing condylar height/width in patients with and without posterior crossbites.

Background: The purpose of this research was to determine the presence of asymmetry of the mandibular condyle in children aged between 7 and 9 years, with a unilateral posterior crossbite, and compare it with a sample of patients without malocclusion.

Material And Methods: The right and left condylar height and width of 401 orthopantomography of children with and without crossbite were measured.

Results: When comparing the height and width of the mandibular condyle in the sample with posterior crossbite we observed that the height and width were almost the same in both condyles.

Root resorption of primary molars and dental development of premolars in children with Osteogenesis Imperfecta medicated with bisphosphonates, grouped according to age and gender.

Background: Osteogenesis imperfecta (OI) is an inherited disorder characterized by bone fragility and skeletal alterations. The administration of bisphosphonates (BPs) to patients with OI reduces pain, thereby improving their quality of life. The main mechanism of action of BPs is the inhibition of osteoclast action.

Genetic variation in the glucosyltransferase-B gene of Streptococcus mutans and its relationship with caries experience in children from Córdoba, Argentina, and with strains from other countries.

Background: Caries is a worldwide distributed oral disease of multifactorial nature, with Streptococcus mutans being the most commonly isolated bacterial agent. The glycosyltransferases of this bacterium would play an essential role in the aetiology and pathogenesis of caries.

Aim: We explored how the glucosyltransferase-B (gtf-B) gene variability of S.

Evaluation of the Severity of Malocclusion in Children with Osteogenesis Imperfecta.

Occlusion is the way in which the dental arches are related to each other and depends on craniofacial growth and development. It is affected in patients with Osteogenesis Imperfecta (OI) who present altered craniofacial development. The malocclusion present in 49 patients diagnosed with different types of OI aged between 4 and 18 was studied.

Ectopic Eruption of Maxillary First Permanent Molars: Preliminary Results of Prevalence and Dentoskeletal Characteristics in Spanish Paediatric Population.

The ectopic eruption of the maxillary first permanent molar (EEM) is a local alteration of dental eruption with a multifactorial aetiology. The aims of our study were to determine the prevalence of the EEM in children and to analyse whether there is a relationship between EEM and dento-skeletal characteristics. A total of 322 children were analysed with the Ricketts cephalometric study and descriptive and analytical statistical analysis was carried out.

Evaluation of the accuracy of the Nolla method for the estimation of dental age of children between 4-14 years old in Spain: A radiographic study.

The aim of this study was to estimate the age of subjects from their dental age by showing the different stages of tooth development using the Nolla method in a Spanish population sample considering the gender, age group, and the development of the two dental arches. The sample consisted of 604 orthopantomographs corresponding to Spanish children (male: 302 and female: 302) aged from 4 to 14 years old. The resulting chronological and dental ages were compared using Student's t-test.

Study of the influence of crossbite on the size of the apical area in a child population by analyzing panoramic X-ray.

Background: The apical area is the space in the maxillary bones that contains teeth during formation and is subsequently occupied by the apices of the permanent teeth. Its dimensions are easy to perceive and determine by observing a panoramic X-ray. Our objective was to analyze the influence of crossbite on the size of the anterior and mesial apical area in Caucasian children.

Sexual dimorphism of primary dentition in Spanish children.

Aim: To analyse differences in the eruption of primary teeth between both sexes.

Materials And Methods: A cross-sectional study was performed in a sample of 1250 children aged between 3 and 42 months. The clinical emergence of teeth was taken to estimate average ages for primary teeth eruption.

How to improve communication with deaf children in the dental clinic.

It may be difficult for hearing-impaired people to communicate with people who hear. In the health care area, there is often little awareness of the communication barriers faced by the deaf and, in dentistry, the attitude adopted towards the deaf is not always correct. A review is given of the basic rules and advice given for communicating with the hearing-impaired.

Dental treatment for disabled children in the Spanish Public Health System.

The Spanish Public Health System is stepping up its efforts to meet all the medical needs of the population. Oral health is of increasing interest for society, especially for parents who are keen for their children to have healthy teeth. Disabled children with both physical and mental disabilities do not always receive the dental care they need.
