Reasons why erupted third molars are extracted in a public university in Mexico.

PURPOSE: The aim of this study was to determine the reasons for which erupted third molars (3M) are extracted in a sample of Mexican patients. SUBJECTS AND METHODS: A retrospective cross-sectional study was performed on a sample of 83 patients attending exodontia (minor oral surgery) clinics of a public university in Mexico (Autonomous University of Hidalgo State). The outcome variable was the reason for extractions using Kay and Blinkhorn's classification. The independent variables were age, gender, arch and tooth number according to the World Health Organization (WHO). For statistical analysis, we used the Chi-squared test in Stata 9.0. RESULTS: Eighty-three patients underwent 150 3M extractions. Mean age was 38.67 ± 13.96 years, and 71.1% were female. The four reasons for 3M extraction were prosthetic (44.0%), followed by orthodontic (24.7%), dental caries (20.0%) and periodontal disease (11.3%). Differences were observed in the reasons for 3M extractions across age groups (p < 0.05). No significant differences existed between men and women (p > 0.05), or the WHO tooth number (p > 0.05). CONCLUSION: Women and patients 18 to 34 years of age had erupted 3M extracted more frequently, primarily for prosthetic reasons. The age profile indicated a trend in demand for services that differ from those of overall tooth extractions, but not for the trend across gender.

Treatment needs for Dental Caries, Restorative Care Index, and Index of Extractions in adolescents 12 and 15 years old / Necesidades de tratamiento para Caries Dental, Indice de Cuidados Restauradores, e Índice de Extracciones en adolescentes de 12 y 15 años de edad

OBJECTIVE: To determine the Treatment Needs Index (TNI) for dental caries, the restorative Care Index (CI), and to introduce a Tooth Extractions Index (TEI) to estimate past and current treatment needs among Mexican adolescents. SUBJECT AND METHODS: A descriptive cross-sectional study was carried out on 1538 adolescents aged 12 and 15 years in the state of Hidalgo, Mexico, to collect decayed, missing, filled teeth (DMFT) data to describe TNI, CI and TEI indices. RESULTS: Higher TNI was identified in younger male teenagers who had always lived in the same community, without dental visits in the last year, and who had poorer socio-economic markers. Higher CI was found in older, female subjects who had moved in their lifetimes to a new community in the area, with dental visits in the last year and who had better socio-economic markers. Higher TEI was found in older, female teenagers who had moved in their lifetimes to a new community in the area, without dental visits in the last year, and who had worse socio-economic markers. CONCLUSIONS: We observed high rates of treatment needs for dental caries and little experience of restorative treatment. While dental extractions due to advanced caries should ideally be zero, relatively few adolescents had this treatment experience. Despite the fact that the overall background of these adolescents is rather homogeneous, it was still possible to find that treatment needs'indices (past and present needs) appeared to be modified by sociodemographic and socio-economic variables.

OBJETIVO: Determinar las necesidades de tratamiento para caries dental (INT), el índice de cuidados restauradores (IC) así como proponer un índice que haga referencia a las extracciones dentales (IE), para estimar necesidades de tratamiento actual y pasada en adolescentes mexicanos. MATERIAL Y MÉTODOS: Se realizó un estudio transversal descriptivo en 1538 adolescentes de 12 y 15 años en el Estado de Hidalgo, México. Empleando el índice CPOD se calcularon los índices TNI e IC; asimismo se propone un IE a las que ha estado expuesta la población. RESULTADOS: El INT fue mayor en los de 12 años, hombres, los que vivieron siempre en la misma comunidad, que no tuvieron visita al dentista en el último año, y con marcado nivel socioeconómico bajo. El IC fue mayor en los sujetos de 15 años, las mujeres, con migración interna, que si tuvieron visita al dentista en el último año, y con mejor nivel socioeconómico. El IE fue mayor en los de 15 años, mujeres, con migración interna, que no tuvieron visita al dentista en el último año, y con peores condiciones socioeconómicas. CONCLUSIONES: Se observaron altas necesidades insatisfechas de tratamiento para caries dental y poca experiencia de tratamiento restaurador. Las extracciones se observaron en pocos adolescentes, considerando cero como ideal. A pesar de que los antecedentes de estos adolescentes es bastante homogéneo, fue posible encontrar que los índices de necesidades de tratamiento (necesidades presentes y pasadas) parecen ser modificados por variables socio-demográficas y socioeconómicas.

[The prescription of drugs in a dental clinic of a Mexican university hospital]. / Prescripción de medicamentos en una clínica odontológica de una universidad mexicana.

OBJECTIVE: To assess the drug prescription service in a dental clinic of a Mexican university hospital. METHOD: An observational, descriptive study was carried out which analysed 698 drugs prescribed for dental problems in 14 dental health care departments in our clinic between the period of January-June 2005. The following criteria were established: prescribed drug, indication, dosage, dosage interval, individualised treatment, treatment duration and potential drug interactions. Information taken from prescriptions and clinical records was compared with information from literature on the subject in order to determine the adequacy of prescription criteria. RESULTS: The most frequently prescribed drugs were paracetamol, naproxen, ampicillin and dicloxacillin (43.26, 15.38, 7.45 and 7.02%). The prescription criteria which showed the least adequacy were as follows: indication, dosage and dosage interval. The main potential drug interactions occurred between non-steroidal anti-inflammatory drugs and captopril/amoxicillin. CONCLUSIONS: Taking the above into consideration, it was determined that 37.25% of prescriptions were inadequate. This study has helped to establish strategies which will facilitate the appropriate use of drugs in the future.

Prescripción de medicamentos en una clínica odontológica de una universidad mexicana / No disponible

Objetivo: Evaluar la prescripción de medicamentos en una clínica odontológica de una universidad mexicana. Método: Mediante un estudio observacional y descriptivo, se analizaron 698 prescripciones odontológicas en 14 servicios clínicos que conforman la clínica en estudio, enfocados a la conservación y restauración de la salud bucal en enero-junio 2005. Se registraron criterios como: medicamento prescrito, indicación, dosis, intervalo de dosificación, individualización de la terapia, duración de tratamiento y presencia de interacciones farmacológicas potenciales. Para determinar la inadecuación en los criterios de prescripción se comparó la información obtenida en recetas y expedientes clínicos, con la de la literatura especializada. Resultados: Los medicamentos más prescritos fueron paracetamol, naproxeno, ampicilina y dicloxacilina en 43,26, 15,38, 7,45 y 7,02%. La indicación, dosis e intervalo de dosificación fueron los criterios con mayor inadecuación en la prescripción. Las principales interacciones potenciales fueron entre los antiinflamatorios no esteroideos con el captopril y la amoxicilina. Conclusiones: Con lo anterior, se determinó que el 37,25% de las prescripciones fueron inadecuadas. A través de este estudio se establecieron estrategias que permitirán en un futuro tener una política de uso racional de los medicamentos empleados
