RESUMEN

OBJECTIVE: The purpose of this critical review is to assess if children and adolescents with hyposalivation are more affected by dental caries than those with normal flow rate. DESIGN: A literature search was performed using keywords and MeSH terms related to hyposalivation and dental caries in the Medline/PubMed, Web of Science, Cochrane Library, Scopus, LILACS/BBO databases and in gray literature without language or date restrictions until March 2022. Observational studies that accessed the presence of dental caries in patients up to 18 years-old with hyposalivation and compared with a control group (normal salivation rate) were considered eligible. The results from search were imported to EndNote Web, where duplicates were removed followed by title/abstract and full text analysis. RESULTS: A total of 12,236 non-duplicated studies were found and 14 fulfilled the criteria and were included in the present review, 9 cross-sectional and 5 cohorts. Stimulated salivary flow rates were assessed in 3644 participants, aged 3-17 years. Three cohort and three cross-sectional studies observed association between low salivary flow rates and the presence of dental caries, while the other 9 included articles did not verify this association. However, the absence of a standard criteria for the hyposalivation classification in young patients was observed and brough light to this important limitation among the studies. CONCLUSION: The salivary flow rate estimation for caries risk assessment must be the target of further studies to make possible and reliable, homogeneous, and unbiasedly assessment of the association between hyposalivation and dental caries in young patients.

RESUMEN

Tuberous sclerosis complex (TSC) is an autosomal dominant disorder with a multisystemic character that may present alterations in multiple organ systems, including oral manifestations. This case report describes a family (mother and two sons) with TSC that underwent a multidisciplinary approach, emphasizing their oral manifestations and highlights the adequate approach taken. The children presented many and distinct features of TSC in different systems; however the family revealed similar oral manifestations. The oral findings were dental enamel pits on permanent teeth and spread gingival fibromas on both jaws. The dental planning was the same for all three patients and included guidelines on oral hygiene and dietary habits, fluoride therapy and a preventive approach through six-month reevaluations. In multisystemic disorders, early multidisciplinary action is vital to provide comprehensive care and reduce or even prevent complications from the condition, thus ensuring the patient's quality of life.

RESUMEN

Los estudios relacionados a las enfermedades orales y la repercusión de éstas en la calidad de vida de niños pre-escolares son relatados por terceros. Objetivando evaluar la percepción de los responsables cuanto al impacto de la salud oral en la calidad de vida de ellos, fue aplicado el instrumento ECOHIS-B (Early Chilhood Oral Health Impacts Scale - Brasil). Se entrevistó a 60 personas responsables por niños de 3 a 6 años de edad de la clínica de odontopediatría de una institución de enseñanza pública brasileña. Fue realizado un examen clínico en los niños para determinar la presencia de lesiones de caries, dientes restaurados y perdidos e índices de biofilm y sangramiento de la encía. La escala del ECOHIS-B varió de 0 a 30, con media de 10,53 (DP=8,30); 52 niños (86,6%) presentaron por lo menos un impacto, dolor de diente (60%) y dificultad para comer (50%) fueron los más frecuentes. Por cada diente acometido por caries (p=0,0001), diente con presencia de caries en dentina (p=0,008) y diente restaurado (p=0,001) la correlación con el ECOHIS-B total fue estadísticamente significativa. La salud oral (n= 36; 59,9%) y general (n=52:86,6%) fueron consideradas por la mayoría de los responsables buena o muy buena al ser comparadas a la de otros niños, y 18 (30%) de ellos percibían que el bienestar de los niños podría ser perjudicado por problemas orales. Problemas con los dientes y tratamientos dentales generan un impacto significativo en la calidad de vida y esto puede ser percibido por el responsable

The repercussions of oral diseases on the quality of life of preschool children are described by the caregivers, rather than the children themselves due to their age. The ECOHIS-B (Early Childhood Oral Health Impacts Scale - Brazil) was used to assess the caregiver's perception of the impact of oral health related to the quality of life of their preschool children. A group of 60 caregivers and their respective 3 to 6 year-old-children were interviewed. At this time these children were being treated at the paediatric dentistry clinic of a Brazilian public university. The children were given a clinical examination to determine carious lesions, missing and restored teeth and biofilm and gingival bleeding indexes were recorded. The ECOHIS-B score ranged from 0 to 30 and the mean score was 10.53 (SD = 8.30); 52 (86.6%) children presented at least one impact. The most frequent impacts were toothache (60%) and eating difficulties (50%). With regard to decayed teeth (p = 0.0001), tooth with dentin cariess (p = 0.008) and restored teeth (p = 0.001) the correlation with the total ECOHIS-B score was statistically significant. Oral (n = 36: 59.9%) and general health (n = 52: 86.6%) were considered good or very good by most caregivers of their own children and 18 (30%) of them perceived that their child's well-being could be affected by oral disorders. In conclusion, dental problems and treatments for children produce a significant impact on their quality of life, a fact which is also perceived by their caregivers
