Objective: To determine the caries risk by Caries Management by Risk Assessment (CAMBRA) for children with mixed dentition attending a Basic Health Unit (BHU), identifying the main dental caries disease indicators, risk factors and protective factors. Material and Methods: The sample consisted of 89 children of both genders aged 8-12 years. Clinical and bitewing radiographic examinations were performed by a calibrated examiner, as well as the filling of the adapted CAMBRA form. Dental caries disease indicators, risk factors and protective factors of all subjects were determined. Chi-square test and multivariate logistic regression analysis for all CAMBRA variables were applied (p<0.05). Results: Caries risk was considered high in 38.2% of patients, moderate in 32.6% and low in 29.6%. The most frequent disease indicator was white spot lesion on smooth surfaces (73.0%), the most common risk factor was visible biofilm (78.7%) and protective factor was fluoridated water (100.0%). Children with "moderate risk" and "high risk" had risk of visible cavities or radiographic penetration of the dentin (OR=14.689; OR=574.363, respectively) compared to patients with "low risk". Conclusion: Caries risk determined as "high" and "moderate" were classifications most observed among children attending BHU. White spot lesions on smooth surfaces were the most frequent dental caries disease indicators and visible plaque on tooth surface and community water fluoridation were the most significant risk factors and protective factors, respectively.

Many studies have evaluated the impact of different oral health problems on oral health-related quality of life (OHRQoL), 1-4 since there is an increasing understanding that oral disorders can have a significant impact on physical, social and psychological well-being. 1 This understanding has resulted in a greater clinical focus on improving quality of life as a major objective of dental care for conditions that are not life threatening. 1,5 Even though dental caries along with traumatic injuries are the most commonly related causes of early loss of primary teeth (ELPT), 6-8 evidence regarding the impact of ELPT on OHRQoL is lacking.The impact of tooth loss has been extensively studied and it negatively impacts OHRQoL in adults and elderly individuals, 9 but to the best of our knowledge, only one cross-sectional study has evaluated this issue in children, therefore stating a negative impact early loss
