Purpose: Literature search shows that there is less evidence of the association between snack parenting styles and dental caries. This study aimed to assess the snack parenting style of mothers of children aged 7-8 years and its association with the dental caries status of their children.

Methods: This study used a sequential mixed-method approach. In the quantitative phase, the Parenting around SNAcking Questionnaire (P-SNAQ) was used to assess the snack parenting style of mothers. DMFT/deft indices were used to record the dental caries status of their children. In the qualitative phase, in-depth face-to-face interviews were conducted. Through a thematic approach, codes and themes were derived.

Results: A total of 600 mother-child pairs participated. Autonomy support was the most common type of snack parenting style (n = 283). There was no significant association between snack parenting style and children's dental caries status. Five themes were derived: (1) Scenarios of snacking; (2) Parental factors affecting snacking; (3) Snack intake influencers; (4) Unhealthy strands; (5) Healthy alternatives.

Conclusion: Snack parenting styles did not influence the dental caries status of children. Those who had snack regulations at home or school were more likely to prefer healthy snacks. Mothers expressed the need for branded healthy snacks.

Purpose: Molar-incisor hypomineralisation (MIH) impacts children's oral health and quality of life, but research on the stomatognathic system of unilateral cases, remains limited. This study evaluated the effects of unilateral MIH on the stomatognathic system in children, focusing on postural and masticatory activities and occlusal force contacts.

Methods: In this cross-sectional observational study, 28 children (mean age: 8.21 years) were divided into two groups: without MIH (CG) and with unilateral MIH (MIHG). Electromyography (EMG) evaluated the activity of masseter and temporalis muscles during various jaw postures and habitual chewing. Occlusal force contacts were measured using T-SCAN®. Comparisons were made between groups and sides. Statistical analysis employed the Shapiro-Wilk test, Wilcoxon signed-rank test, and paired t-test, with a significance level of 5%.

Results: EMG data demonstrated increased muscle hyperactivity in MIHG compared to CG at rest for the left temporalis muscle on the contralateral side (p < .001), during left laterality for the right temporalis muscle on the ipsilateral side (p = 0.04), and habitual chewing of soft food for the left temporalis muscle on the contralateral side (p = 0.02). Greater voluntary contraction was observed on the unaffected side in MIHG for the temporalis muscle at rest (p = 0.01) and the masseter muscle during right laterality (p = 0.02). No significant differences were found in occlusal force measurements between groups or sides.

Conclusions: This study indicates that unilateral MIH is associated with increased muscle hyperactivity in the contralateral temporalis and masseter muscles, without significant differences in occlusal force.

Aim: The aim was to investigate the salivary amino acid profile in children with protein-energy undernutrition (PEU) and its association with caries experience in the presence of other risk factors.

Methods: The study had a cross-sectional design and was carried out with 122 children (12-71 months old), classified according to their level of undernutrition (mild-GI, n = 22; moderate-GII, n = 53) or healthy controls (GC, n = 47). The children were categorized based on the presence of caries into caries-experienced groups (ceos > 0, 22 CG, 12 GI and 18 GII) and caries-free groups (ceos = 0, 25 CG, 10 GI and 36 GII). Total unstimulated and stimulated saliva were collected to determine amino acids and Streptococcus mutans, respectively.

Results: Eighteen amino acids were associated with PEU. Undernutrition and caries experience influenced the presence of the following amino acids: L-anserine, asparagine, ethanolamine, gamma-aminobutyric acid, and norleucine. Asparagine was a significant predictor of a lower probability of caries experience in a logistic regression model.

Conclusions: Salivary amino acids are associated with undernutrition in children, and the presence of asparagine in saliva relates to a lower caries risk.

Purpose: Assess the knowledge and attitudes of parents/guardians regarding their children's oral health and their preferences regarding the treatment of carious primary teeth.

Methods: A cross-sectional study including the completion of a questionnaire by parents/guardians of healthy children aged 2-12 years attending the Department of Pediatric Dentistry (NKUA). Data were collected through 35 questions regarding demographic characteristics of the participants, oral hygiene and dietary habits, and parents' knowledge of the importance of oral health and primary teeth. Treatment preferences were assessed through clinical scenarios accompanied by colored clinical photographs. Results were presented in frequency tables and comparisons with specific child and parent-characteristics were evaluated using chi-squared and Fisher's exact test.

Results: Parents were mainly females (73%), married (81%), aged > 40 years (56%), and high school graduates (57%). Most children brushed alone (56%), twice (48%) daily, with a manual toothbrush (65%) and consumed sugary snacks daily (38%). More than two-thirds of parents recognized the relationship between oral hygiene and general health (82%) and the importance of primary teeth (72%). Almost all parents would like to restore their children's asymptomatic (94%) and symptomatic (98%) primary teeth, with pulp therapy and stainless-steel crowns being the treatment of choice (58%). The decision on treatment about cavitated/non-cavitated primary teeth was not correlated with any of the parental or child-related factors. Acceptance of minimally invasive treatments was higher among highly educated parents and parents of boys.

Conclusion: Insight into parents' perceptions and preferences regarding the treatment of primary teeth is necessary and should be considered during treatment planning.

Purpose: The purpose of this study is to evaluate the influence of photobiomodulation therapy on the regenerative potential of non-vital mature permanent teeth of healthy Canine dogs.

Methods: 54 mature roots, obtained from 27 premolars, in dogs, were selected and divided into three equal groups where Group I received regenerative endodontic procedures (REPs) using blood clot as a scaffold (positive control), Group II received similar treatment as Group I, followed by photobiomodulation therapy (study group) and Group III did not receive any intervention (negative control). Each group was further divided into three equal subgroups for the evaluation of the vascular area percentage and fibroblast count at 3 different intervals; 3, 10, and 15 weeks. Statistical analysis was performed with R statistical analysis software version 4.1.3 RESULTS: Data analysis for vascular area percentages, revealed an insignificant increase in mean values at 3 and 10 weeks for both the positive control and study group, and all values were significantly lower than the negative control (p < 0.001). At 15 weeks, there was an insignificant difference between the study group and the negative control group, with mean values was 9.76 ± 2.25, and 11.97 ± 2.37, respectively. However, both values were significantly higher than the positive control group (2.47 ± 1.0), (p < 0.001). Regarding fibroblast count, there was a gradual increase in mean values recorded at different intervals, reaching its maximum at the 15th week period; they were 41.40 ± 1.14, 56.60 ± 6.11 and 44.67 ± 17.04 for positive control, study group, and negative control respectively, with insignificant differences between the study group and negative control.

Conclusion: The results of this study support the revascularization of non-vital mature permanent teeth as an alternative treatment modality. Photobiomodulation could improve the construction of regenerated blood vessels and fibroblasts. However, further studies with longer flow-up periods and different animal models are recommended.

Objective: The aim of this study was to assess symmetry of developmental stage of permanent teeth between the left and right side of the jaw, as well as between the maxilla and the mandible.

Methods: A sample of 150 panoramic radiographs of individuals aged 6-20 years (69 males, 81 females) were selected from an open-access radiographic collection (Maxwell Museum of Anthropology's orthodontic collection, Albuquerque, USA). All developing immature permanent teeth (n = 489) were scored by the first author using Moorrees and Demirjian tooth stages. Symmetry of developing teeth was assessed between the left and right sides of the jaw, as well as between the maxilla and the mandible using McNemar test with p < 0.05 considered significant.

Results: No significant differences were found comparing left and right sides within the maxilla (n = 489), (McNemar, p = 0.759 M, p = 0.736 D), or within the mandible (McNemar, p = 0.262 M, p = 0.707 D) using either tooth scoring method. Percentage agreement for individual teeth between left and right sides was least for third molars. Significant differences were observed comparing maxillary and mandibular teeth for both tooth scoring methods (n = 978), (McNemar, p = 0.00 M, p < 0.001 D). Percentage agreement for individual teeth between the maxilla and mandible was least for incisors.

Conclusion: In the present sample, differences in tooth formation were not significantly different in left and right side of the jaw while a significant difference (p = 0.00 M, p < 0.001 D) was observed between maxilla and mandible.
