ABSTRACT: Root resection (RR) is a therapeutic option for furcation lesions grade II and III, fracture of one of the roots and root caries. The aim of the study was to evaluate in each selected period (5, 8 and 10 years) the percentage of maintenance of molars that underwent RR therapy with furcation lesions grade II and III or with root fractures. Subjects received the therapy with RR in molars with periodontitis, with furcation lesion grades II or III, and with fractures, caries or endodontic reason, in one of the roots. The supportive periodontal therapy was made for at least one annual session during the assessed time. For the clinical therapy to be considered successful, the tooth is remaining in functional loading, without mobility above grade I, pocket depth ≥ 4 mm, absence of bleeding on probing or exudate, fractures and root caries. Were evaluated the files of 37 patients, 15 males and 22 females, with a mean age of 51.4 (SD = ± 12.46), with a total of 44 teeth with RR, 27 upper and 17 lower molars. The survival rates after the RR was 97.73 % for 05 years of evaluation (44 teeth), 95.35 % for the 08 years (43 teeth) and 97.57 % for the 10 years (41 teeth). 35 teeth were restored with total crows isolated or abutment of fixed prosthesis. The survival rates after 10-years was 90.91 %, and there was no statistical difference between the types of restorations performed and the tooth survival rate.

RESUMEN: La resección de la raíz (RR) es una opción terapéutica para lesiones de furca de grado II y III, fractura de una de las raíces y caries de la raíz. El objetivo del estudio fue evaluar en cada período seleccionado (5, 8 y 10 años) el porcentaje de mantenimiento de los molares que se sometieron a terapia RR con lesiones de furca de grado II y III o con fracturas de raíz. Los sujetos recibieron la terapia con RR en molares con periodontitis, con lesión de furca de grado II o III, y con fracturas, caries o razón endodóntica, en una de las raíces. La terapia periodontal de apoyo se realizó durante al menos una sesión anual durante el tiem- po evaluado. Para que la terapia clínica se considere exitosa, el diente permanece en carga funcional, sin movilidad por encima del grado I, profundidad de bolsillo ≥ 4 mm, ausencia de sangrado al sondaje o exudado, fracturas y caries de raíz. Se evaluaron los archivos de 37 pacientes, 15 hombres y 22 mujeres, con una edad média de 51,4 (DE = ± 12,46), con un total de 44 dientes con RR, 27 molares superiores y 17 inferiores. Las tasas de supervivencia después del RR fueron del 97,73 % durante 5 años de evaluación (44 dientes), 95,35 % para los 8 años (43 dientes) y 97,57% para los 10 años (41 dientes). Se restauraron 35 dientes con cuervos totales aislados los pilares de prótesis fija. Las tasas de supervivencia después de 10 años fueron del 90,91 %, y no hubo diferencia estadística entre los tipos de restauraciones realizadas y la tasa de supervivencia dental.

ABSTRACT: Gingival recessions are characterized by partial denudation of the root surface due to apical displacement of the gingival margin from the amelocemental junction and may be localized or generalized. The aim of this study was evaluate the prevalence of gingival recession and dentine hypersensitivity of dental students of Federal University of Juiz de Fora, Brazil. Were examined 80 students with on average age of 22.9, randomly selected to assess the prevalence, level of gingival recession and the presence of dentinal hypersensitivity. Fifty students had at least one gingival recession and dentine hypersensitivity was observed in 28 students. Buccal surface was the most prevalent (86.6 %), with measures mostly between 1 and 2 mm (92 %) and classified as Class I Miller (96.25 %). The pre-molars were the group most frequently affected teeth (37.35 %). Gingival recession with small measures is a very common condition in young patients.

RESUMEN: Las recesiones gingivales se caracterizan por una denudación parcial de la superficie radicular debido al desplazamiento apical del margen gingival, desde la unión amelocemental y puede ser localizada o generalizada. El objetivo de este estudio fue evaluar la prevalencia de la recesión gingival y la hipersensibilidad dentinaria en estudiantes de Odontología de la Universidad Federal de Juiz de Fora, Brasil. Se examinaron 80 estudiantes con una edad promedio de 22,9, seleccionados al azar para evaluar la prevalencia, el nivel de recesión gingival y la presencia de hipersensibilidad dentinal. En cincuenta estudiantes se observó al menos una recesión gingival y se reportó hipersensibilidad a la dentina en 28 estudiantes. La superficie oral fue la más prevalente (86,6 %), con medidas principalmente entre 1 y 2 mm (92 %) y clasificada como Clase I Miller (96,25 %). Los premolares fueron el grupo de dientes afectados con mayor frecuencia (37,35 %). La recesión gingival con medidas pequeñas es una condición muy común en pacientes jóvenes.

Em decorrência da quimioterapia, alterações na cavidade oral podem ser observadas e levar a complicações sistêmicas importantes, podendo aumentar o tempo de internação hospitalar, os custos do tratamento e afetar diretamente a qualidade de vida dos pacientes. Este trabalho teve como objetivo realizar uma pesquisa em um hospital de oncologia da cidade de Juiz de Fora (MG), sendo realizado através de coleta de dados nos prontuários de pacientes que estiveram em tratamento oncológico, onde foram avaliadas as prevalências das manifestações orais em relação ao sexo, idade e tipo de tumor. Verificou-se que a mucosite foi a manifestação mais incidente em ambos os sexos em todas as faixas etárias (15,5%). A xerostomia e as demais lesões, como candidíase e lesões aftosas, também estiveram presentes. É possível melhorar a qualidade de vida antes, durante e após as terapias antineoplásicas através de um protocolo de atendimento odontológico que inclua medidas de condicionamento do meio bucal prévia à quimioterapia, como profilaxia, remoção de cáries, tratamento periodontal e de focos periapicais, orientação para higiene oral e dieta, e ainda laserterapia. É importante a inserção do dentista na equipe oncológica para o diagnóstico precoce das manifestações bucais e acompanhamento no período de tratamento.

Several changes in the oral cavity due to chemotherapy can be observed and can lead to important systemic complications, increasing the time of the patient in hospital and the costs of the treatment as well as affect the quality of life of the patients. The aim of this study was to assess the oral manifestation in patients treated with chemoterapy according to sex, age and tumor type. Data was collected in an oncology hospital in Juiz de Fora, Minas Gerais State, from patients' records that were submitted to oncologic treatment. It was possible to verify that mucositis, associated or not to other type of lesions, was the most common lesion in both sex of all ages (15.5%). Xerostomia and other lesions, such as Candida infection and aphthous lesions, were also present. It is possible to improve the quality of life of the patient during and after anti-neoplastic therapies through a protocol of odontological assistance that includes changes of the oral environment previous to chemotherapy such as profilaxis, caries removal, treatment of periodontal and periapical lesions, oral hygiene instructions, diet orientation and laser therapy. It is very important the insertion of the dentist in the oncologic medical team for the early diagnosis of the oral manifestation and follow-up during treatment time.
