ABSTRACT
PURPOSE: This study aimed to determine the frequency of abnormalities in the newborn oral cavity and to evaluate the association with prenatal and perinatal factors. METHODS: This cross-sectional study evaluated 2,216 newborns. Oral findings were assessed in the first 24 hours of life using visual examination. Sex, weight, length, gestational age, and medical disorders at birth were recorded. Maternal demographic and medical information was also obtained. RESULTS: The most common oral findings were Bohn's nodules, Epstein's pearls, and dental lamina cysts. Other intraoral findings included odontogenic cysts, ankyloglossia, and natal teeth, among others. In logistic regression analyses, folic acid consumption during pregnancy was significantly associated with Bohn's nodules (odds ratio [OR], 1.79; 95% confidence interval [CI], 1.23-2.55; P=0.002), Epstein's pearls (OR, 1.63; 95% CI, 1.14-2.33; P=0.007), and dental lamina cysts (OR, 1.45; 95% CI, 1.02-2.05; P=0.038). Moreover, preterm births were negatively associated with prevalence of Bohn's nodules (OR, 0.63; 95% CI, 0.50-0.80; P≤0.0001). Comparison between newborns with and without oral inclusion cysts showed that maternal folic acid and iron intake were significantly different (P<0.05). CONCLUSION: Maternal folic acid and iron intake were associated with the prevalence of oral inclusion cysts.
ABSTRACT
The aim of the study was to investigate the distribution of mutans streptococci (MS) infection of caries-free (CF) and caries-active (CA) preschool Mexican children by microbial and molecular assays. Eighty preschool children were divided into two groups, 40 CF and 40 CA children. Saliva samples were inoculated onto MSB to identify CFU and DNA extractions were tested by PCR. Our results indicated that there was no statistical difference (p > 0.05) between groups either in age, weight, height or sex. S. sobrinus was detected by PCR twice as much in the CA group, the difference being statistically significant (p < 0.05). dmfs index was positive correlated with S. mutans (r = 0.2941, p = 0.0081), S. sobrinus (r = 0.3384, p = 0.0021) and S. mutans-S. sobrinus (r = 0.3978, p = 0.0003). ANCOVA revealed that dmfs index had a significant effect on the distribution of CFU of S. mutans (p = 0.0118) and S. sobrinus (p = 0.03). When MSB was compared with PCR to identify MS, there was no statistical difference (p > 0.05). We conclude that S. mutans and S. sobrinus were isolated in higher numbers from CA children and those harbouring both bacteria had higher dmfs scores. PCR is a useful tool in molecular epidemiology for dental caries studies; it was effective in detecting and identifying MS from saliva in children.

Synovial Chondromatosis (SC) is a disease whose etiology is unknown, can be defined as a benign synovial process characterized by the formation of metaplastic cartilaginous nodes inside connective tissue of articular surfaces, is considered an active metaplastic phenomenon better than a neoplastic process; it presents a greater preference to affect women who constitute almost 70% of reported cases, the age range is wide and oscillates between 18-75 years (average 44.6 years). Between the main clinical findings are: pain, crackle, volume augmentation and a limited buccal opening. SC is an unusual state and the reports in the English literature are no more than 75 cases, only 66 of those where histologically verified, most of those were affecting great joints like hip, knee and shoulder, but if SC is not frequent in this sites, is even more infrequent on temporomandibular joint. The aim of this paper is to report a clinical case and at the same time to realize a brief review of the literature.

La condromatosis sinovial (CS) es una enfermedad de etiología desconocida, la cual pude definirse como un proceso benigno sinovial caracterizado por la formación de nódulos cartilaginosos metaplásicos dentro del tejido conectivo de las superficies articulares, se le considera un fenómeno metaplásico activo más que un proceso neoplásico; presenta una marcada preferencia por afectar a mujeres constituyendo casi el 70 por ciento de los casos reportados, el rango de edad es amplio y oscila entre los 18 y 75 años con una media de 44.6 años. Dentro de los principales hallazgos clínicos destacan: sintomatología dolorosa, presencia de crepitación, aumento de volumen y limitación de la apertura bucal. La CS es una entidad poco frecuente de la cual se han reportado no más de 75 casos en la literatura inglesa, sólo 66 de ellos comprobados histológicamente, la mayoría afectando principalmente grandes articulaciones como cadera, rodilla y hombro; pero si la frecuencia es rara en estas localizaciones, lo es más aún en la articulación temporomandibular. El objetivo del presente artículo es el de reportar un caso clínico a la vez que se realiza una breve revisión de la literatura

Existen en la literatura pocos reportes en relación a la evaluación de los cambios morfofuncionales secundarios a la ligadura de la arteria carótida externa en forma bilateral, por lo que se realizó este procedimiento en 8 conejos para evaluar los cambios clínicos e histológicos posteriores a la ligadura, utilizando como parámetros de medición la observación clínica y los estudios histopatológicos mediante la toma de biopsias selectivas, reportándose los resultados

El campo de acción en que se desarrolla el cirujano dentista no debe restringirse al trabajo habitual del consultorio, sino que debe formar parte de un equipo médico en donde su colaboración con otros especialistas sea de apoyo terapéutico y diagnóstico en padecimientos tanto bucales como sistémicos. El presente trabajo consistió en efectuar una revisión de la literatura relacionada con los usos diagnósticos de la saliva. Asimismo, se reportan dos casos de mujeres sometidas a hiperestimulación ovárica, a quienes se les efectuaron determinaciones seriadas de estradiol sérico y salival simultáneamente, encontrándose un alto grado de efectividad y confiabilidad del uso de la saliva como un medio no invasivo para efectuar procedimientos diagnósticos de utilidad práctica no solo para el odontólogo, sino para el médico en general
