Evaluation of plaque index, gingival index and oral health-related quality of life in obese patients / Evaluación del índice de placa, índice gingival y calidad de vida relacionada con la salud bucal en pacientes obesos

Obesity is a chronic disease that may be related to caries, periodontitis, xerostomia, and dental erosion, as well as increasing morbidity and mortality. The aim of this study was to evaluate the plaque index (Silness & Löe, 1964), the gingival index (Löe & Silness, 1963), and the oral health-related quality of life (OHRQoL) in obese patients. The study included 45 extremely obese, 45 obese, and 45 normal-weight individuals between the ages of 18 and 58. The plaque index and gingival index of the individuals were determined by clinical examination by probing. In addition, the Oral Health Impact Profile-14 (OHIP-14) questionnaire was used for the OHRQoL. The IBM SPSS Statistic 22.0 software program was used for the statistical evaluation of the study data. The plaque index and gingival index values were statistically higher in obese compared to normal weight individuals (p0.05). There was no statistically significant difference between the OHIP-14 total scores of the groups (p>0.05). Increased apparent plaque index and gingival index values in obese patients may adversely affect periodontal health.

La obesidad es una enfermedad crónica que puede estar relacionada con caries, periodontitis, xerostomía y erosión dental, además de aumentar la morbimortalidad. El objetivo de este estudio fue evaluar el índice de placa, el índice gingival y la calidad de vida relacionada con la salud bucal (CVSB) en pacientes obesos. El estudio incluyó a 45 individuos extremadamente obesos, 45 obesos y 45 de peso normal entre las edades de 18 y 58 años. El índice de placa y el índice gingival de los individuos se determinaron mediante examen clínico y sondaje periodontal. Además, se utilizó el cuestionario Oral Health Impact Profile-14 (OHIP-14) para la evaluación CVSB. Se utilizó el programa informático IBM SPSS Statistic 22.0 para la evaluación estadística. Los valores del índice de placa y del índice gingival fueron estadísticamente más altos en obesos en comparación con los individuos de peso normal (p0,05). No hubo diferencia estadísticamente significativa entre las puntuaciones totales de OHIP-14 de los grupos (p>0,05). El aumento del índice de placa aparente y los valores del índice gingival en pacientes obesos pueden afectar negativamente la salud periodontal.

Serum Leptin Concentrations in Extremely Obese Childen

PURPOSE: The purpose of this study is to investigate whether there is a difference in leptin concentrations between those of children of normal weight and extremely obese children. METHODS: We measured serum concentrations of leptin in 70 extremely obese subjects(7 to 12 years, 20 girls and 50 boys), whose serums had been frozen at -70degrees C. Height, weight, obesity index, and body mass index were measured. Radioimmunoassay for serum leptin was performed using Human Leptin RIA Kit. RESULTS: The mean age was 10.1 years old. The mean serum concentration of leptin in extremely obese children was 15.0+/-6.8ng/ml. The mean leptin level in girls was 15.2+/-6.7ng/ml compared with 15.0+/-6.7ng/ml in boys(P=0.91). The mean obesity index in girls was 58.7+/-8.1% compared with 62.1+/-11.2% in boys. The mean body mass index in girls was 25.6+/-1.9 compared with 26.8+/-2.1 in boys. Serum leptin concentrations correlated with the body mass index(r=0.38, P=0.001). The mean leptin level in the extremely obese group was significantly higher than that in the normal group of the same age(range, 10 to 12 years, P<0.001). CONCLUSION: Serum leptin concentrations highly correlated with body mass indices in extremely obese children. Because serum leptin levels in extremely obese children were remarkably high compared to those in normal group and there was no difference in leptin levels between girls and boys, it is speculated that obese children are resistant to endogenous leptin production.
