The identification of the skeletal maturation stage of the cervical vertebrae has proven an important reference for orthodontic diagnosis. The aim of the present study was to determine the association between the skeletal maturation stage of the cervical vertebrae and types of malocclusion according to the age and gender of participants. A total of 361 individuals (168 males and 193 females) between 8 and 14 years of age were selected from a convenience sample. Malocclusions were diagnosed through study models using the Angle classification. Maturation stages of the cervical vertebrae were determined using the method proposed by Hassel and Farman. Statistical analysis involved the chi-square test (p £ 0.05) and multiple logistic regression (forward stepwise procedure). Significant differences were observed between the stage of skeletal maturation of the cervical vertebrae and gender at ages 11, 12 and 14 years. Males with Class II malocclusion were twice as likely to be in Stage 1 or 2 of cervical vertebra maturation than individuals with Class I malocclusion (OR = 2.1 [CI 95%, 1.33-3.18]). There were no differences between individuals with Class I and Class III malocclusions. The association between skeletal maturation of the cervical vertebrae and type of malocclusion was significant, suggesting a skeletal component in the determination of Class II malocclusions.

The aim of this study was to compare the mandibular size in boys and girls with Class I and Class II skeletal patterns, taking into consideration the bone maturation stage, as defined by the cervical vertebrae maturation. One hundred and sixty cephalometric radiographs were obtained from subjects (aged between 7 and 12 years) with Class I or Class II skeletal patterns, according to the ANB angle and WITS appraisal. The Class I sample consisted of 80 subjects (40 boys, 40 girls). The Class II sample also consisted of 80 subjects (40 boys, 40 girls). On a cross-sectional basis, mandibular length (Co-Gn) was compared between groups and genders. The between-stages changes were also evaluated, with the cervical vertebrae analysis used for establishing the bone maturation stages at CS2, CS3, CS4 and CS5. The results were statistically analyzed by the Kruskal-Wallis test. The mandibular length differed between skeletal patterns only at the earlier stages of development. In the Class I pattern, the mandibular lengths of boys were greater than those of girls at stages CS2, CS4 and CS5, whereas in the Class II pattern, the mandibular lengths of boys were greater than those of girls at stages CS2, CS3 and CS4. The present results indicate a sexual dimorphism in the mandibular length at almost all stages of bone maturation, in exception of the CS5 stage in Class II.

El presente estudio tuvo por objetivo alertar y orientar al cirujano dentista cuanto a los efectos colaterales de medicamentos antihipertensivos en la boca. Método: Fueron seleccionados 150 pacientes (75 del sexo masculino y 75 del sexo femenino), de la edad entre 17 y 91 años, portadores de hipertensión arterial sistémica del Programa de Control de Hipertensión Arterial de una Unidad Básica de Salud. La hipo salivación fue evaluada a través de examen clínico intraoral y de cuestionario. Resultados: se evidenciaron que más de la mitad de la muestra presentó la boca seca, siendo la mayoría del sexo masculino, cerca de 50% de los pacientes utilizaban más de una droga. Las drogas más utilizadas por el sexo masculino fueron: hidroclorotiazida, nifedipina y metildopa, mientras que en el sexo femenino fueron: hidroclorotiazida, clohidrato de propranolol y metildopa. Conclusión: la secreción salival es influenciada por la acción de drogas antihipertensivas y que el cirujano dentista debe estar preparado para el diagnóstico y tratamiento de los efectos colaterales bucales de estas drogas.

La anquilosis de la  A.T.M. es  una patología clasificada conforme el local donde ocurre, el tipo de tejido envuelto y su extensión. El tratamiento debe ser quirúrgico, con remoción del cóndilo e interposición de algún tipo de material autógeno o alo plástico en el espacio formado.
