Impact of a Maternal Motivational Interviewing on Oral Health in the Mother-Child Dyad.

Motivational Interviewing (MI) has been included in dentistry programs. There exists a need for interventions in the mother-child dyad. The aim of this paper was to compare the effects of a MI-based educational program on oral care knowledge, attitudes, and practices (KAP) in the mother-child dyad to a Traditional Education-based program (TE). A community intervention trial was carried out. The experimental and control groups were made up of women between 18 and 45 years of age in the sixth month of gestation. Both groups were provided with TE. The experimental group additionally received a session based on the principles of the MI. Socio-demographic data, children's oral health KAP (COHKAP), that of the mother (MOHKAP), and maternal self-efficacy (MSE) in relation to children's oral health (COHMSE) were recorded. A baseline measurement was made, as well as a six-month follow up. The participants included 135 women with an average age of 24.88 ± 6.00. After intervention, the experimental group's COHKAP, MOHKAP, and COHMSE all increased (p < 0.001). When MI-based interventions are combined with TE, MSE and dental care KAP for the mother-child dyad in pregnant women can be improved.

Knowledge, practices and perceptions regarding oral health preventive measures among Mexican dental students: a cross-sectional survey study.

Although oral diseases are mostly preventable, they remain a global public health problem. Thus, there is a need for trained personnel to actively intervene in promoting oral health, to prevent and timeously detect oral diseases, and, in turn, to provide comprehensive quality healthcare. The main objective of the study was to evaluate the knowledge, practices and perceptions regarding oral health preventive measures amongst undergraduate dental students. This cross-sectional study was conducted between the period October 2017 and January 2018. The subjects included were undergraduate students of the dental science program at the School of Dentistry, in Leon Guanajuato, Mexico. A validated questionnaire was used to identify knowledge of preventive dentistry and the frequency of oral health preventive actions in the dental school clinics. Besides, perception towards prevention in dentistry was assessed. A total of N=232 undergraduate students participated of whom 65.9% (N=153) were women. More than half of the students 59.5%, (N=138) rated their knowledge on the prevention of oral diseases as good, followed by 32.8% (N=75) of students who rated it as regular. 49% (N=97) of the students performed frequently preventive treatments in their daily clinical practice. 90% (N=217) think that the main reason of low practice of prevention in dentistry is the lack of commitment of the dentist. 72.8% (N=169) mention that there should be professionals dedicated exclusively to preventive dentistry. Students of second grade demonstrated better prevention knowledge and tended to engage more frequently in preventive activities (p<0.05). In conclusion, our study found that, second-year students perform preventive practices more frequently and these practices decrease as their studies progress. It should be sought to create positive attitudes towards prevention not only in the year in preventive dentistry, but also throughout the entire career. This enables students to become trained professionals that can deliver preventive services to their patients.

Effect of silver diamine fluoride on adhesion and microleakage of a pit and fissure sealant to tooth enamel: in vitro trial.

AIM: To identify the effect of silver diamine fluoride in adhesion and microleakage of a pit and fissure sealant to tooth enamel. METHODS: An in vitro study including 120 human molars without caries, and caries grade 1 was performed. Molars were randomly divided into four groups. Occlusal surfaces of groups 2 and 4 were sealed. In groups 1 and 3 silver diamine fluoride (SDF) was placed in the occlusal surface and then molars were sealed according to manufacturer's instructions. Afterwards, all groups were submitted to the adhesion test. Groups 1 and 2 were placed in a forming cylinder and their roots were submerged in polymethyl methacrylate after that they were stored in deionised water (37 °C ± 1). Subsequently, they were tested by applying a tractional load (Instron machine, speed cross of 1 mm/min). Sealant adhesion was evaluated through: Resistance to the detachment (MPa), residues of sealant area (mm2) and adhesive remaining index (ARI) (0-3 interval). Microleakage test: Groups 3 and 4 were placed in a plastic container and subjected to 2000 cycles at different temperatures one at 6 °C ± 1 and the other at 60 °C ± 1. Later the occlusal surface was immersed for 24 h in 1% toluidine blue. Microleakage was observed by optical microscopy (10×) and was interpreted in micrometres. RESULTS: Of the samples without SDF 18.1 and 23.0% of the sealant remaining and of the samples with SDF present 100% of sealant remaining on enamel. Samples with SDF obtained an average in the test of detachment of 6.89 ± 3.09 MPa, whereas in the group without SDF the average obtained was 6.42 ± 3.35 MPa. Differences were not statistically significant (p = 0.579). Most of the samples not treated with SDF (81.6%) showed microleakage than those treated with SDF in which 47% presented microleakage. CONCLUSIONS: There is an improvement in the retention properties of a fissure sealant applied after treatment with silver diamine fluoride. The application of fissure sealant to improve the aesthetics of teeth treated with SDF is recommended.

Oral-health-related quality of life in schoolchildren in an endemic fluorosis area of Mexico.

OBJECTIVE: To evaluate the oral-health-related quality of life (OHRQoL) of children living in an endemic hydrofluorosis area. METHODS: Schoolchildren aged 8-10 years living in an area with 3.38 ppm F water concentration completed a validated Spanish version of the Child Perceptions Questionnaire (CPQ(8-10ESP)). World Health Organization (WHO) criteria were applied for the diagnosis of dental caries and malocclusion. Additionally, the Thylstrup and Fejerskov Index (TFI) was used for fluorosis diagnosis. CPQ(8-10ESP) scores and oral health status were analyzed using non-parametric tests and logistic regression models. RESULTS: Two hundred and twelve schoolchildren participated in this study. The mean CPQ(8-10ESP) score was 12.98 (SD 11.4). General oral health was rated as "poor" in 14.6%, "fair" in 41.5%, "good" in 25.9%, and "very good" in 17.9% of the children. Regarding overall well-being, half (51.6%) of the children perceived that the condition of their mouths disturbs their quality of life (QoL). Children with dental fluorosis (TF >4) had a high CPQ(8-10ESP) score in all domains (P < 0.005). Additionally, children with DMFS + dmfs >5 had higher scores in the oral symptoms, functional limitation, and emotional well-being CPQ(8-10ESP) domains (P < 0.05). Applying a CPQ(8-10ESP) cutoff point of 32, the OR values for severe malocclusion, caries, and fluorosis were 5.2 (P = 0.034), 4.6 (P = 0.006), and 5.1 (P = 0.007), respectively. CONCLUSIONS: Malocclusion, caries, and fluorosis were associated with a negative impact on children's QoL.
