## 4 Discussion  
In recent years, the prevalence of caries and periodontal disorders in industrialised countries has decreased in adults and children due to the use of preventive measures. However, the data collected by our screening did not show the same situation between migrants and asylum seekers. Data collected from the literature show that the migrant status may be related to a higher prevalence of dental caries [7, 8, 9, 10, 11, 12, 13] and a lower periodontal condition [14, 15, 16]. Difficulties ensuring access to basic needs for migrant populations, such as food, water, sanitation, and health care, have been documented in the literature [17]. Research conducted in Colombia in 2019 [18] has suggested and demonstrated that oral health is considered a secondary problem for vulnerable people who have to change their lifestyle and adapt to another culture. However, several studies [19, 20] show that \begin{table}

Refugees and asylum seekers have difficulty gaining access to oral health care [21]. The health system, society, and personal behaviour in the area of oral health determine access to health care services. The health policy of the host country is a crucial element in determining access to oral health care. The highest prevalence of caries in the group of migrants in the research of [PERSON] et al. [22] was associated with difficulties in gaining access to health services. [PERSON] et al. (Germany) [23] noted in their study that the incidence of oral disorders is greater in people with low socioeconomic status, such as as asylum seekers who find themselves having to overcome many difficulties to start their lives again in a foreign country. The study by [PERSON] et al. [24] reported that pain was the most commonly presented disorder in 444 patients, stating that more than half of the dental treatments carried out were extractions, 74.1% of which were due to caries. Similarly, pain was a common symptom reported by participants in the research of [PERSON] et al. [25], and more than half of the participants reported needing dental care, but not being able to receive it given their low socioeconomic status. Research by [PERSON] et al. [26] shows that periodontal disease and dental caries are the most frequently assessed study conditions. [PERSON] et al. [27] analysed oral hygiene practices among refugees, noting that most brushed their teeth less than twice a day, thus having poor oral hygiene. The oral hygiene practices and behaviours of parents inevitably directly influence the oral health of children. Literacy and parents' education regarding good oral health practices may reduce the dmft/DMFT value for their children [28]. A study conducted in Canada between 2013 and 2016 by [PERSON] et al. [29] found that approximately 60% of refugee children had never visited a dentist before while most Canadian counterparts had seen a dentist in the last year.
