Periodontitis en niños sanos de 3 años. Dos casos con seguimiento a 5 años / Periodontitis in healthy 3-year-old children. Two cases with 5-year follow-up

Resumen Objetivo La periodontitis en dentición primaria es excepcional en niños sin enfermedades sistémicas. El objetivo de este informe es describir las características clínicas y radiográficas de dos casos de niños de 3 años sistémicamente sanos con periodontitis, y su tratamiento con seguimiento a 5 años. Casos clínicos En ambos casos, a los 3 años de edad los niños fueron derivados al especialista en periodoncia por su odontopediatra debido a la pérdida muy temprana de incisivos inferiores. El examen clínico y radiográfico mostró pérdida de inserción clínica, pérdida ósea y movilidad dental en otros incisivos superiores e inferiores. Se realizó la interconsulta médica y se descartó que los niños padecieran enfermedades relacionadas con el diagnóstico de periodontitis como manifestación de una enfermedad sistémica. El tratamiento consistió en la instrucción de medidas de higiene bucal que debían ser ejecutadas por los padres, instrumentación subgingival, antisépticos locales, medicación antibiótica sistémica y mantenimiento periodontal. No se realizaron extracciones como parte del tratamiento. En ambos casos uno de los incisivos presentes al momento de la consulta se perdió prematuramente, antes de los 4 años. El resto de los incisivos primarios cumplieron su ciclo normal. Luego de 5 años de seguimiento, a la edad de 8 años, ambos niños presentaban los incisivos y los primeros molares permanentes periodontalmente sanos y el resto de los dientes primarios sin signos de periodontitis.

Abstract Aim Periodontitis in primary dentition is exceptional in children without systemic diseases. The objective of this article is to describe the clinical and radiographic characteristics of two cases of systemically healthy 3-year-old children with periodontitis, and their treatment, with a 5-year follow-up. Clinical cases In both cases, at 3 years of age, the children were referred to a periodontic specialist by their pediatric dentist, due to the very early loss of lower incisors. Clinical and radiographic examination showed loss of clinical attachment, bone loss and dental mobility in other upper and lower incisors. A medical consultation was carried out and diseases related to the diagnosis of periodontitis as a manifestation of a systemic disease were ruled out. The treatment consisted of instruction on oral hygiene measures that had to be carried out by the parents, subgingival instrumentation, local antiseptics, systemic antibiotic medication, and periodontal maintenance. No extractions were performed as part of the treatment. In both cases, one of the incisors present at the time of consultation was lost prematurely, before the age of 4 years. The rest of the primary incisors completed their normal cycle. After 5 years of follow-up, at the age of 8 years, both children showed periodontally healthy incisors and first permanent molars, and the rest of the primary teeth without signs of periodontitis.

Periodontitis en niños sanos de 3 años: dos casos con seguimiento a 5 años / Periodontitis in healthy 3-year-old children: two cases with 5-year follow-up

Objetivo: La periodontitis en dentición primaria es ex- cepcional en niños sin enfermedades sistémicas. El objetivo de este informe es describir las características clínicas y ra- diográficas de dos casos de niños de 3 años sistémicamente sanos con periodontitis, y su tratamiento con seguimiento a 5 años. Casos clínicos: En ambos casos, a los 3 años de edad los niños fueron derivados al especialista en periodoncia por su odontopediatra debido a la pérdida muy temprana de inci- sivos inferiores. El examen clínico y radiográfico mostró pér- dida de inserción clínica, pérdida ósea y movilidad dental en otros incisivos superiores e inferiores. Se realizó la intercon- sulta médica y se descartó que los niños padecieran enferme- dades relacionadas con el diagnóstico de periodontitis como manifestación de una enfermedad sistémica. El tratamiento consistió en la instrucción de medidas de higiene bucal que debían ser ejecutadas por los padres, ins- trumentación subgingival, antisépticos locales, medicación antibiótica sistémica y mantenimiento periodontal. No se rea- lizaron extracciones como parte del tratamiento. En ambos casos uno de los incisivos presentes al momento de la con- sulta se perdió prematuramente, antes de los 4 años. El resto de los incisivos primarios cumplieron su ciclo normal. Luego de 5 años de seguimiento, a la edad de 8 años, ambos niños presentaban los incisivos y los primeros molares permanentes periodontalmente sanos y el resto de los dientes primarios sin signos de periodontitis (AU)

Aim: Periodontitis in primary dentition is exceptional in children without systemic diseases. The objective of this article is to describe the clinical and radiographic charac- teristics of two cases of systemically healthy 3-year-old chil- dren with periodontitis, and their treatment, with a 5-year follow-up. Clinical cases: In both cases, at 3 years of age, the chil- dren were referred to a periodontic specialist by their pediat- ric dentist, due to the very early loss of lower incisors. Clin- ical and radiographic examination showed loss of clinical attachment, bone loss and dental mobility in other upper and lower incisors. A medical consultation was carried out and diseases related to the diagnosis of periodontitis as a mani- festation of a systemic disease were ruled out. The treatment consisted of instruction on oral hygiene measures that had to be carried out by the parents, subgingival instrumentation, local antiseptics, systemic antibiotic medication, and perio- dontal maintenance. No extractions were performed as part of the treatment. In both cases, one of the incisors present at the time of consultation was lost prematurely, before the age of 4 years. The rest of the primary incisors completed their normal cycle. After 5 years of follow-up, at the age of 8 years, both children showed periodontally healthy incisors and first permanent molars, and the rest of the primary teeth without signs of periodontitis (AU)

Subgingivally applied minocycline microgranules in subjects with chronic periodontitis: A randomized clinical and microbiological trial.

The aim of this study was to evaluate clinical and microbiological effects of subgingival minocycline microgranules when used as an adjunct to scaling and root planing in subjects with Chronic periodontitis. Twenty-six non-smoker volunteers participated in the study. Four opposite sites, clinically standardized, with bleeding on probing (BOP) and pocket depth (PD) ≥ 6 mm were selected. Baseline BOP, PD and Clinical attachment level (CAL) were measured and microbiological samples were collected from the study sites and analyzed using PCR. Porphyromonas gingivalis (Pg) Tannerella forsythia (Tf), Treponema denticola (Td) and Aggregatibacter actinomycetemcomitans (Aa) were detected. One side of the mouth was randomly allocated to the experimental treatment: scaling and root planing plus minocycline microgranules (Test group=T) and the other side of the mouth to scaling and root planing alone (Control group=C). At days 30 and 90, clinical and microbiological examination was repeated. After 30 days BOP was reduced to 81% in C and to 12% in T and at day 90 to 58% in C and to 8% in T (p<0.05). PD was significantly reduced in both groups (C: 4.8mm, T: 4.2mm) favoring T at days 30 and 90 (p<0.05). CAL reduction at day 30 showed no difference between groups. At day 90, CAL reduction was higher in T (p<0.05). At days 30 and 90 Pg, Tf, Td and Aa was reduced in both groups. Pg reduction was significantly greater in group T. At day 90 frequency of sites with Td decreased in T and increased in C (p<0.05). No adverse effect was observed. This study showed that minocycline microgranules adjunct to scaling and root planing resulted in grater reduction of BOP and PD, higher CAL gain, increased probability of Pg suppression and retarded recolonization of Td than root instrumentation alone.

Subgingivally applied minocycline microgranules in subjects with chronic periodontitis: a randomized clinical and microbiological trial / Microgránulos de minociclina subgingival en sujetos con periodontitis crónica. Estudio clínico y microbiológico aleatorizado

El objetivo de este estudio fue evaluar el efecto clínico y microbiológico de microgránulos de Minociclina, colocados subgingivalmente como coadyuvante del raspaje y alisado radicular en pacientes con Periodontitis crónica severa. Participaron 26 sujetos voluntarios con Periodontitis crónica, no fumadores. Se seleccionaron 4 sitios contralaterales con Sangrado al Sondaje (SS) y Profundidad al Sondaje (PS) > 6 mm. Condición Basal (CB): se registró, PS y Nivel de Inserción (NI). Se determinó mdiante PCR la presencia de Porphyromonas gingivalis (Pg), Tannerella forsythia (Tf), Treponema denticola (Td) y Aggregatibacter actinomycetemcomitans (Aa). Un lado de la boca fue aleatoriamente asignado al tratamiento experimental: grupo T, el otro al tratamiento control: grupo C. Al día 30 y 90 se repitieron los exámenes clínicos y microbiológicos. Día 30: el SS se redujo al 81 por ciento en el grupo C y al 12 por ciento en el grupo T (p<0,05). Estas diferencias se mantuvieron al día 90 (C: 58 por ciento, T: 8 por ciento) (p<0.05). Día 30 y 90: hubo disminución de la PS en ambos grupos, siendo significativamente mayor en el grupo T (p<0,05). En ambos grupos hubo disminución significativa del NI (p<0,05), no hubo diferencias entre los grupos al día 30 y sí al día 90. A los 30 y 90 días en ambos grupos se redujo la prevalencia para Pg, Tf ,Td y Aa. A los 30 y 90 días la reducción de sitios con Pg fue mayor en el grupo T (p=0,002). A los 90 días Td disminuyó en el grupo T y aumentó en el grupo C (p=0,023). No se observaron efectos adversos. Los resultados mostraron que la aplicación subgingival de microgránulos de minociclina adjunta al raspaje y alisado radicular produjo una reducción mayor del SS, la PS y el NI que el raspaje y alisado solo, aumentó la probabilidad de suprimir Pg y retardó la recolonización con Td.
