Prevalence and factors associated with dental erosion in individuals aged 12–30 years in a northeastern Brazilian city

Abstract

Background/PurposeDental erosion in young individuals has increased significantly in recent years, due to changes in lifestyle. Thus, the present study investigated the prevalence and factors associated with dental erosion in individuals aged 12–30 years in the city of Imperatriz of Maranhão, Brazil.Materials and methodsA cross-sectional study was conducted on 335 individuals who answered a questionnaire consisting of variables related to dental erosion. Afterwards, the individuals were subjected to clinical examinations and the basic erosive wear examination index was used to classify their teeth according to the presence and severity of dental erosion.ResultsDescriptive statistics, the chi-square test, Poisson univariate and multivariate regression were performed at 5% level of significance. The sample was characterized by 204 females (60.9%), the majority of whom were from 12 to 19 years of age (78.5%), among whom 28.7% presented dental erosion. Their monthly family income was from 1 to 3 minimum wages (56.4%). The variables that were significantly associated with the outcome were family income, chewing gum, and consumption of soft-drinks/juices before going to sleep (p=0.03, p=0.001, and p=0.04, respectively). Individuals who chewed chewing gum were 2.27 times (95% CI =1.43–3.60) more likely to present dental erosion than those who did not chew gum. Individuals who ingested soft drinks or juices were 2.30 times (95% CI =1.30–4.10) more likely to present dental erosion.ConclusionThe prevalence of erosion reflected the need for programs of prevention and guidance for patients about the etiological factors of the disease.

Prevalence of erosive tooth wear in Chilean adults, 2016: A cross‐sectional study

“…In our study, most of the participants examined had BEWE cumulative scores between 9 and 13 (59.25%); this indicates a medium risk level according to the Bartlett et al classification . Alaraudanjoki et al found a higher frequency of BEWE sum scores 3 to 8; Luciano et al reported a frequency of 83.9% for BEWE cumulative scores between 0 and 2; Olley et al reported that 30% of individuals had BEWE cumulative scores between 9 and 13; and Vered et al found that only 6.4% had BEWE scores of 7 or above. It is also important to note that some of the studies presented their prevalence results according to specific tooth surfaces, as was the case for the Bartlett et al study in Europe which analysed buccal and lingual surfaces .…”

“…The prevalence detected in our study (97.9%; considering the highest BEWE score ≥2 on at least one tooth surface) was very high compared with data in the literature. Indeed, we found the highest prevalence in our population compared with adults with the same cut‐off (≥2), such as 34% in Israel, 15.1% in China, 21.3% in Northern Finland, 4.7% to 6.8% in Brazil and 13.4% in Poland . However, there was less of a difference when we compared the prevalence with the Bartlett et al study in seven European countries in which they reported that erosive tooth wear affected 54.4% of participants in the United Kingdom, even including only buccal and lingual/palatal surfaces .…”

“…It is important to note that the incisal surface was not evaluated in all of the studies reviewed. This surface was evaluated in the studies of adults by Chu et al and Sun et al in China and Luciano et al in Brazil . This resulted in a difference in the total number of surfaces examined with respect to canine and incisor groups.…”

“…. In addition, Manaf et al (2012) found a prevalence of 68% in 19‐ to 24‐year‐old people in Malaysia; Chu et al (2015) reported a prevalence of 44.4% (BEWE ≥ 1) in a Chinese population of 18‐ to 21‐year‐olds; Olley et al (2015) reported a prevalence of 93% (BEWE ≥ 1) in 19‐ to 34‐year‐old individuals in England; Alaraudanjoki et al (2017) reported a prevalence of 75% (BEWE ≥ 1) in a cohort of adults aged between 44 and 46 years old in northern Finland; and Luciano et al (2017) reported that 28.7% of individuals in Brazil had some degree of erosive tooth wear . So far, it is the only published study in adults in South America.…”

“…For each country and with a cut-off of BEWE 2 or 3, the frequency of detecting erosive lesions, in decreasing order, was UK 54.4%, Spain 26.3%, France 26.1%, Italy 21.9%, Latvia/Estonia 17.9% and Finland 17.7%.. 9 In addition, Manaf et al (2012) found a prevalence of 68% 10 reported a prevalence of 75% (BEWE ≥ 1) in a cohort of adults aged between 44 and 46 years old in northern Finland 12 ; and Luciano et al (2017) reported that 28.7% of individuals in Brazil had some degree of erosive tooth wear. 13 So far, it is the only published study in adults in South America.…”
