To evaluate the presence and associated factors of erosive tooth wear (ETW) in children with cerebral palsy (CP), as well as its impact on the oral health-related quality of life (OHRQoL). Parents of 60 CP children, between 6 and 14 years of age, answered the Brazilian version of the parental-caregivers perception questionnaire (P-CPQ). The ETW diagnosis was performed by a single calibrated examiner according to the O'Brien´s modified index. Associated factors such as family income, behavioral factors, and type of CP were also collected. OHRQoL was measured through P-CPQ domains and total score, and Poisson regression was used to correlate ETW to associated factors and to the scores. ETW was present in 48.3% of the children. The multivariate adjusted model showed that the presence of ETW was associated with more than 2 days of soft drink intake per week (p = 0.003), daily intake of powdered juice (p = 0.002) and reported gastroesophageal reflux (p = 0.016). The family income higher than one Brazilian minimum wage showed a positive impact on the CP children's OHRQoL (RR = 0.53; p ≤ 0.001). ETW in CP children is associated to frequent consumption of soft drinks, powdered juices, and reported gastroesophageal reflux; however, ETW has not a negative impact on the OHRQoL.

Purpose:It aimed to explore the degree of difficulty of caries-detection-associated-topics perceived by dental students and lecturers as pedagogical step in the development of learning objects for e-learning.Methods:A convenience sample comprising ninety-eight subjects from different academic levels (undergraduate/graduate students and pediatric dentistry lecturers) participated. Two spreadsheets (isolated/relative) were created considering key topics in the caries detection process. The isolated evaluation intended to explore each topic in an isolated way, while the relative intended to classify, comparatively, the participants’ perceived difficulty per topic. Afterwards, data were analyzed. All values on spreadsheets were combined obtaining the subject’s final perception. Associations between the subjects’ degree of the perceived difficulty and academic level were estimated. ANOVA was used to determine differences regarding the perception among evaluated topics in distinct groups.Results:Caries histopathology and detection of proximal carious lesions were the topics perceived as the most difficult in the process of caries detection by both students and lecturers. Differentiation between an extrinsic pigmentation and a brown-spot (caries lesion) as well as differential diagnosis between caries and enamel developmental defects or non-carious lesions were considered as more difficult by undergraduates in comparison to graduates/lecturers (regression-coefficient=14.54; Standard Error=3.34; P<0.001 and 8.40, 3.31, and 0.01 respectively).Conclusion:Topics as histopathology and detection of proximal caries lesions were identified as the most difficult despite the academic level. However, some topics are differently perceived according to the group. These results are useful for developing pedagogical material, based on the students real learning needs/expectations.

A erosão dentária é um problema! The dental erosion is a problem! La erosión dental é un problema!

Este problema ocorre em uma condição multifatorial, podendo haver a interação entre os fatores biológicos, químicos e comportamentais. Nos últimos anos a sua prevalência tem aumentado, tornando-a um desafio para os cirurgiões-dentistas, especialmente quando ela alcança estágios mais avançados aonde pode causar dor, hipersensibilidade, problemas com função e estética.Através de uma revisão da literatura, o presente estudo tem como objetivo orientar os cirurgiões-dentistas com informações a respeito da história, etiologia, diagnóstico, prevenção e tratamento do desgaste dentário erosivo. O conhecimento sobre os fatores etiológicos do desgaste dentário erosivo torna-se importante para evitar a progressão deste problema, além de estabelecer medidas preventivas eficazes desde a infância.

AbstractTooth erosion or erosive tooth wear is considered a contemporary oral health problem, caused by chemical processes of "acid attack" to the tooth, without bacterial involvement, which causes the loss of mineral structure. This problem occurs in a multifactorial condition, and there may be an interaction between biological, chemical and behavioral factors. In recent years, its prevalence has increased, making it a challenge for dentists, especially when it reaches more advanced stages where it can cause pain, hypersensitivity, problems with function and aesthetics. Through a literature review, the present study aims to guide dental surgeons with information about the history, etiology, diagnosis, prevention and treatment of erosive tooth wear. Knowledge about the etiological factors of erosive tooth wear becomes important to prevent the progression of this problem, in addition to establishing effective preventive measures since childhood. The dental surgeon must perform an early diagnosis and perform the appropriate treatment of this problem, mainly the guidelines regarding food and oral hygiene in addition to fluoride therapies.

The Atraumatic Restorative Treatment (ART) was originated with the intention of healing the need for dental treatment for poor communities. With the development of the technique there has been an expansion of its use both in public health and in private practices. Through a review of the literature, the objective of this work is to integrate information about the history, evolution, advantages and disadvantages, as well as to increase the knowledge of dentists so that they can perform with more confidence. ART is based on the philosophy of minimal intervention, its use is plausible in several situations, both in public and private services, since the technique preserves healthy tissues and reduces more invasive procedures such as endodontics and exodontia. There is a need for professionals to increase their knowledge of the technique.

Objective To evaluate oxidative stress in saliva of children with dental erosion as compared to children with no erosion.Methods One single examiner, trained and prepared to make diagnosis of dental erosion according to the Basic Erosive Wear Examination index, selected 40 children aged 4 to 6 years, who attended a pediatric dentistry prevention clinic. Two groups were formed - one comprising children with dental erosion (n=22), and another with no dental erosion (n=18). The quantity of dental biofilm was verified using the Simplified Index of Oral Hygiene, and unstimulated saliva was collected for biochemical analyses. The following were assessed in saliva: flow rate, buffering capacity, pH, and total protein concentration. Malondialdehyde levels were also verified to determine oxidative stress and total antioxidant status.Results The quantity of biofilm was smaller in children with mean dental erosion±standard deviation (0.76±0.25), as compared to those with no dental erosion (1.18±0.28). There was no statistical difference in saliva parameters of oxidative stress in children with dental erosion.Conclusion The activity of oxidative stress in saliva did not influence dental erosion process when in its early stages.
