Oral health is perhaps the most neglected aspect of healthcare for persons living in rehabilitation centers, compared to the general population. The caregivers play a vital role in administering daily oral care to residents in rehabilitation centers: The aim of the present questionnaire-based study was to evaluate the caregivers’ knowledge, attitude and practices towards oral healthcare at centers for the intellectually disabled in the Southern region of Saudi Arabia (SA). The present study was designed as a cross-sectional one-point time survey. The samples were selected by using a non-probability convenience sampling method. The self-administered closed-ended questionnaire comprised of 22 items divided into four sections, which was designed to elicit the demographic information, awareness of oral care, attitude towards oral health and practice of the oral healthcare regime among the participants. Of the164 participants, 53.0% and 47.0% were male and female, respectively. Most of the participants—54.9%—were between 30–39 years of age. Participants were almost equally distributed between educational groups, and about 87% had more than 2 years of experience. A brief overview showed a fair level of knowledge and attitude among 61.6% and 58.5% of respondents, respectively. Participants with an education level above that of high school showed good knowledge and attitude scores (p < 0.05), whereas females showed better attitude scores compared to the males (p < 0.05). Respondents mentioned the difficulties they faced while treating the subjects. The special healthcare workers generally had acceptable oral health knowledge and practices. Caregivers who had lower education levels should be advised for training programs that addressed the importance of oral health services.

The applicability of the golden proportion and gingival aesthetic line harmony in natural anterior dentitions remains controversial across different populations. Therefore, it is of interest to evaluate the presence of the golden proportion and gingival aesthetic line characteristics in maxillary anterior teeth among 200 adults using standardized digital photographic analysis. Mesiodistal tooth width ratios were calculated and compared with the theoretical golden ratio (0.618), while gingival zenith positions and gingival line patterns were also assessed. The results showed that both lateral-to-central incisor and canine-to-lateral incisor ratios significantly deviated from the golden proportion, whereas Class I gingival aesthetic line patterns were more consistently observed. Thus, we show that natural anterior aesthetics are not governed by strict mathematical proportions, emphasizing the importance of individualized treatment planning over formula-based approaches.
