A New Approach to Diagnosis to Posterior Cross Bite: Intraoral Photography and Wala Ridge.

A posterior crossbite is an occlusion disorder that occurs in the transverse plane. It occurs when the buccal cusps of the upper premolars and molars engage lingually with the buccal cusps of the lower teeth. It can be unilateral or bilateral (involving one or more teeth) in the primary, mixed, or permanent dentition. A crossbite may appear in early dentition stages and it can be dental or functional. It can lead to skeletal crossbite in mixed dentition. Therefore, early diagnosis and treatment are crucial. MATERIAL AND METHODS: The selected sample included 204 patients in growing stage divided into two groups: a study group of 102 patients with posterior crossbite and a control group of 102 patients without malocclusion. To analyze the pathology, intraoral frontal photographs and study models were taken, in which the bone component was measured from the Wala Ridge. RESULTS: The use of the photographs to study the Wala Ridge was confirmed. The mean maxillary width was 57.8 mm (SD 1.7) and mandibular width was 56.4 mm (SD 1.7) for the control group, with a maxillomandibular difference of 1.4 mm (SD 0.7); and 52.7 mm (SD 3.7) and 55.5 mm (SD 3.6), respectively, with a maxillomandibular difference of -2.8 mm (SD 1.4) for the study group. A higher maxillomandibular discrepancy was observed in patients with a posterior crossbite that involved more than one tooth in addition to the permanent first molar. It was also higher in patients with bilateral posterior crossbite. CONCLUSIONS: Intraoral frontal photography can be used as a diagnostic method to measure the maxillomandibular difference using the Wala Ridge.

Oral health status of 6- to 12-year-old children in Madrid, Spain: A cross-sectional study.

Based on the results of the 2015 oral health survey in Spain, the prevalence of untreated dental caries in temporary dentition, in the six-year cohort was 27,8%, and in the twelve-year cohort 14,6%. Due to the magnitude of the problem, the high health cost and the possibilities of prevention, monitoring the oral health status of the child population is extremely important, as it will allow the implementation of prevention and early care strategies. OBJECTIVES: To study the caries prevalence and malocclusion in the mixed dentition in children aged 6-12 years in Madrid, Spain. . MATERIALS AND METHODS: This is a descriptive, cross-sectional study carried out in the city of Madrid during the 2018-2019 school year. Fifth year students of the European University of Madrid through health surveys, calibrated and supervised by the two main researchers, collected the data. The schoolchildren assessed were students from different schools in the city of Madrid, between 6 and 12 years old. According to WHO standards, data were collected in 2 months. RESULTS: The total number of students examined was 303 students from 4 different schools in the community of Madrid. The prevalence of caries in our sample in the primary dentition was 45.21% with dmf> 0 and in the permanent dentition it was 23.7 % with a DMF> of 0. CONCLUSIONS: The oral health survey carried out in the sample shows a high prevalence of caries, as well as in the dmf and DMF indicators. Most of the children needed fluoride applications, so it would be interesting to evaluate which of them can be prevented with different public health projects.

Manejo de la conducta del paciente maltratado / Management of behavior in the abused patient

Dentro del marco que caracteriza al maltrato y al abuso fÝsico, el odontólogo tiene la posibilidad de ver a Ústos con mßs frecuencia que el mÚdico de cabecera, pediatra u otros profesionales de la salud, pues, como se sabe, los tutores que maltratan a los niños no suelen llevarlos al mismo mÚdico o al mismo centro de salud mßs de una vez para no ser descubiertos. Al trastorno que se desarrolla despuÚs del abuso sexual y del maltrato fÝsico de lo conoce con el nombre de estrÚs postraumßtico. Hemos querido evaluar la bibliografÝa de los últimos 10 años referente al tema del maltrato y manejo de los niños vÝctimas de este fenómeno en el ßrea dental y psiquißtrica, para resaltar la importancia que tiene el perfil psicológico del paciente en el momento de aplicar una tÚcnica de manejo de conducta durante la consulta odontológica. Si bien desde la primera consulta en odontopediatrÝa se deben suponer una voluntad y preocupación especiales por parte del profesional, en el caso del niño vÝctima del maltrato se debe ademßs fomentar la confianza
