RESUMEN
PURPOSE: This study was conducted to investigate the dental and palatal arch dimensions of male and female siblings in relation to gender and age, using three-dimensional (3D) digital casts. METHODS: This study involved 54 subjects (27 pairs) of male-female siblings aged 15 to 45 years. Dental casts were digitized and analyzed for tooth size (TS), arch width (AW), arch length (AL), arch length discrepancy (ALD), and palatal arch dimensions (PAD). The data obtained were subjected to t-tests, and the palatal curvature (PC) was modeled using a fourth-order polynomial. RESULTS: Significant differences (P < 0.05) between the sexes were found in the mesiodistal TS, particularly in all canines, as well as 16, 36, 46, and 41. Maxillary AW and AL were also significantly (P < 0.05) influenced by sexes. Most arch parameters were more prominent in male siblings, and the effect of age on PC differed between the sexes. In addition, the PC of adolescent females was mostly superimposed on adult females relative to males. CONCLUSION: Among siblings, males were found to have significantly larger dental arch dimensions than females. Furthermore, PC showed some differences between the sexes in both the frontal and sagittal planes.
RESUMEN
Objectives: This study aims to explore the information-seeking behavior patterns of parents with children receiving treatment for early childhood caries (ECC). Materials and Methods: Semistructured in-depth interviews were conducted with 20 parents of children with ECC. A topic guide was developed, focusing on questions relating to (i) the timing of their seeking information on ECC, (ii) the types of EEC information they seek, and (iii) the resources used to seek information. The interviews were audio-recorded and transcribed verbatim. Thematic analysis was performed, whereby the data were coded and categorized into themes and subthemes. Results: Four main themes were identified: the immediacy of seeking information, perceived information need, use of resources, and barriers to seeking information. Parents either sought information immediately after detecting changes to the appearance of their child's teeth, with some being aware of the changes after signs and symptoms developed. The types of information parents usually sought covered the disease, its prevention, and management. Common sources of information were friends, family, the internet, and healthcare professionals. Barriers to seeking information discussed by parents were lack of time as well as insufficiency and inaccuracy of the information they received. Conclusion: This study highlighted the need for comprehensive, tailored early education on ECC for parents using reliable information sources. There is also a need to empower other nondental healthcare professionals to provide oral healthcare education for parents.
RESUMEN
PURPOSE: This cross-sectional study aimed to identify impacts of depression, anxiety and stress on periodontitis severity and oral health-related quality of life (OHRQoL). METHODS: A total of 141 periodontitis patients were recruited. Psychological states were assessed using the Malay short-form Depression, Anxiety and Stress Scales (MDASS-21). Subjects were grouped as positive for depression, anxiety or stress (DAS) (positive-DAS), without DAS (non-DAS), stress-only and anxiety-only. OHRQoL was evaluated using the Malay short-form Oral Health Impact Profile (S-OHIP[M]). RESULTS: OHRQoL was associated with MDASS-21, probing pocket depths, recession, clinical attachment levels, number of teeth present and number of teeth with mobility. S-OHIP(M) of positive-DAS subjects was associated with clinical attachment levels, number of teeth present and presence of anxiety. Anxiety-only subjects reported higher S-OHIP(M) scores compared to the non-DAS group. CONCLUSION: OHRQoL of all subjects was negatively impacted by periodontitis severity and tooth loss. Combinations of depression, anxiety or stress led to worse periodontal status and OHRQoL. Subjects with anxiety-only experienced poorer OHRQoL compared to those without depression, anxiety and stress regardless of periodontitis severity. Possible impacts of psychological states on periodontitis and OHRQoL highlights the importance of assessing and improving psychological factors as part of periodontal therapy and to enhance OHRQoL.
