Trends in frequency and prevalence of oral cancer and oral squamous cell carcinoma in mexicans. A 20 years retrospective study
Objective. To establish the time trends of the frequency and prevalence of oral cavity cancer in regard to age and gender in a 20-years (time period 1989 ? 2008) cohort of Mexicans. Design and Setting. 13,235 head and neck biopsies from the archive of the Oral Pathology Laboratory, Dental School, National Autonomous University of Mexico were revised. The cases with diagnoses of oral cancer were selected. Gender and age at diagnosis was obtained from medical records. The frequency and prevalence of oral cavity cancer and oral squamous cell carcinoma were assessed biannually in regard to the total number of population served by the oral pathology laboratory. The statistical significance of trends was established using the linear logistic regression (curve estimation) test (s 0.05). Results. 298 cases (138 males; 160 females) of oral cancer were included; 167 (92 females; 75 males; female:male ratio: 1.1:1) corresponded to oral squamous cell carcinoma. From 1989 to 2008 the prevalence of oral cancer and oral squamous cell carcinoma increased 200% (s 0.05) and 100% (s 0.000) respectively. The increase of frequency and prevalence was observed in both genders however only in females was significant (s 0.000). We do not identify changes in the age at diagnosis. Conclusions. Oral cancer, specifically oral squamous cell carcinoma, has increase in Mexicans females in the last 20 years

ABSTRACT Multidisciplinary treatment for oral rehabilitation of a partially edentulous patient with atrophic process is paramount to emit correct diagnosis and to determine the most convenient treatment plan which might restore appropriate masticatory function and adequate aesthetics. The clinical case here presented is that of a partially edentulous 51 year old male. The periodontics, prosthetics, and orthodontic departments jointly concurred in emitting a total rehabilitation diagnosis. As part of the treatment, it was decided to orthodontically extrude upper right central and lateral incisors in order to achieve enhanced bone levels. Five months into the treatment, four implants were put into place; in a simultaneous fashion, elevation of the maxillary sinus fl oor was undertaken. This process was performed with the Caldwell Luc technique, with the use of an electrical hand-piece device. During the same surgical procedure, another implant was placed in the area of the left upper fi rst molar. Elevation of the sinus fl oor was conducted following Summers technique. Six months after placing the implants, implants were uncovered and healing abutments were put into place. Three months later, a prosthetic rehabilitation was initiated by placing an implant-supported prosthesis on the right side of the upper jaw, a single zircon crown on the implant in the fi rst upper left molar, and a bilateral, partially removable prosthesis on the lower jaw. Achieved results, with respect to function and aesthetics, were deemed satisfactory by the patient. RESUMEN El manejo multidisciplinario para la rehabilitaci贸n bucal de un paciente parcialmente desdentado con un proceso atr贸fico, es de suma importancia para lograr un diagn贸stico correcto y as铆 poder determinar el tratamiento m谩s adecuado, devolviendo la funci贸n masticatoria y est茅tica. El caso cl铆nico que se presenta es de un paciente masculino de 51 a帽os de edad parcialmente desdentado, el cual fue diagnosticado en conjunto con los departamentos de periodoncia, ortodoncia y pr贸tesis para su rehabilitaci贸n bucal. Dentro del tratamiento se decidi贸 realizar la extrusi贸n forzada lenta, ortod贸ncicamente asistida, de los 贸rganos dentarios (o.d.) central y lateral superior derecho para mejorar el proceso 贸seo y posteriormente hacer la colocaci贸n de cuatro implantes end贸seos, realizando simult谩neamente la elevaci贸n de piso de seno maxilar, utilizando la t茅cnica de Caldwell Luc con piezoel茅ctrico. En el mismo acto quir煤rgico se realiz贸 la colocaci贸n de otro implante en la zona del primer molar superior izquierdo y se realiz贸 elevaci贸n del piso de seno con la t茅cnica de Summers. Seis meses posterior a la colocaci贸n de implantes se realiz贸 el descubrimiento de los mismos y se colocaron tornillos de cicatrizaci贸n. Tres meses despu茅s, se inici贸 con la rehabilitaci贸n prot茅sica, colocando una pr贸tesis fi ja implanto soportada de zirconia en la zona del maxilar superior derecho, una corona individual de zirconia en el implante del maxilar superior izquierdo y una pr贸tesis parcial removible bilateral inferior. Los resultados que se obtuvieron fueron satisfactorios para el paciente tanto en funci贸n como en est茅tica
