Objective:To determine the treatment needs for dental caries and the restorative care index on the permanent dentition of Nicaraguan children. Subjects and Methods:In a cross-sectional study, 1379 schoolchildren aged 6 to 12 years old were evaluated clinically to determine the decay, missing and filled teeth (DMFT) index and to calculate the need for dental caries (TNI) and care indices (CI). Sociodemographic, socio-economic and behavioural data were collected using questionnaires. Results: The mean age was 9.04 ± 1.98 years and 50.2% were female. A relatively higher percentage of TNI was observed in the following groups: younger children (78.0%), males (60.1%), children of higher birth order (69.1%), the children of older mothers (56.7%), having a negative attitude toward oral health (59.9%), with preventive dental care in the past year (94.2%), less frequent tooth brushing (66.3%), with greater presence of plaque (53.9%), larger family (56.3%), higher socio-economic position [SEP] schooling (60.9%) and lower SEP occupation (58.9%). In addition, we observed a higher percentage of CI amongst the following: older children (52.2%), females (49.9%), those of a lower birth order (47.7%), children of young mothers (47.2%), those with a positive attitude toward oral health (48.6%), receiving preventive/curative dental care in the past year (74.3%), most frequently brushing teeth (51.9%), less presence of plaque (50.0%), small family (45.9%), lower SEP school (53.5%) and higher SEP occupation (52.9%). Conclusions:We show that Nicaraguan children have high treatment needs for dental caries but had little experience of restorative care.
Objective: To identify if the presence of dental plaque, dental brushing frequency and preventive dental care are related to the high severity of dental caries. Methods: A case-control study was carried out on a sample of schoolchildren aged 6 to 12 years. We selected 677 children from public schools in the city of León Nicaragua, 283 cases y 394 controls. Using questionnaires addressed to mothers / guardians, a series of sociodemographic, socioeconomic and dental variables were collected. Through oral clinical examination, the dmft and DMFT caries indexes were determined for primary and permanent dentition. The dependent variable was the high severity of caries, which was coded as (1) "dmft + DMFT = 0" and (2) "dmft + DMFT ≥ 6". The chi-square test and the Mann-Whitney test were used in the statistical analysis. Results: In the bivariate analysis, we observed that the associated variables (p<0.05) to high caries severity (dmft + DMFT ≥ 6) were: younger age of the child, younger age of the mother, less brushing frequency, presence of dentobacterial plaque and the pattern of dental care. Conclusions: The results of the study show that the variables related to oral hygiene, both objective measurement (presence of dentobacterial plaque) and subjective measurement (selfreport of toothbrushing frequency), are associated with high severity of dental caries. In addition, according to the pattern of dental care showed association with the severity of caries.
Objectives: To determine the factors associated with dental caries in the primary and permanent dentition of children attending a paediatric dentistry clinic at a public university in central Mexico. Methods: A cross-sectional study was performed using the medical records from 309 patients aged 2 to 12 years who attended the Paediatric Dentistry Specialty Clinic at the Autonomous University of the State of Mexico between January 2014 and December 2015. The dependent variables were the experience of caries for each dentition (dmft index for primary dentition and DMFT index for permanent dentition), which were obtained from the clinical history in the diagnostic records. The independent variables were diverse sociodemographic, socioeconomic, and oral and general health indicators. Statistical analysis was performed using nonparametric tests in Stata. Results: The mean age was 5.71±2.43 years and 50.8% were men. The mean dmft index was 8.53±4.18 (prevalence=99%), while the DMFT index was 1.91±2.02 (prevalence=58.9%). The variables age, number of siblings, presence of syndrome, dental pain experience, dental pain presence, as well as oral hygiene with help showed statistically significant differences with dmft. Similarly, age, number of siblings, and dental pain experience were statistically significant with DMFT. Conclusions: The caries experience observed in this sample of self-selected patients was high. We identified several variables associated with dental caries in both dentitions.
