Hajdu‐Cheney syndrome (HCS) also known as Cranio‐skeletal dysplasia is a rare genetic disorder of bone metabolism. It is mainly characterized by acro‐osteolysis and generalized osteoporosis. The other distinctive features include a dysmorphic face, short stature, aplasia of facial sinuses, and persistent cranial sutures. Although the condition begins to manifest since birth, the characteristic features become more prominent with age. This syndrome is usually recognized by dentists due to these craniofacial abnormalities. This case report aims to highlight a case of 6‐year‐old girl HCS who presented with aberrant facial features, premature exfoliation of teeth, unusual mobility of teeth and atypical root resorption in primary dentition.

Background/Aim: Individuals with special healthcare needs (SHCN) are more likely to sustain traumatic dental injuries (TDIs) due to distinct risk factors. The aim of this review was to assess various risk factors associated with TDIs in individuals with SHCN. Materials and Methods: The protocol was designed according to the recommendations of the Cochrane‐handbook, Joanna Briggs Institute, and the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines and registered in PROSPERO (CRD42022357422). A comprehensive search was performed in PubMed, LILACS, Web of Science, EMBASE and Scopus using a pre‐defined strategy without any limitation of language and year of publication. It was last updated on 25 April 2023. Studies addressing the TDIs in individuals with SHCN were included. Data extraction and analyses were performed, risk of bias (ROB) assessment was done using the Joanna Briggs Institute's critical appraisal tool, and a meta‐analysis was performed using random‐effects model. Results: A total of 21 studies were included in the review. They were categorized according to the target disease/condition: cerebral palsy (n = 5), ADHD and autism spectrum disorders (n = 5), visually impaired (n = 4), and multiple disorders (n = 7). The studies showed variability in the design and methods; however, 17 out of 21 studies showed moderate to low ROB. Increased overjet and lip incompetence were the main risk factors reported in the studies. The commonest injuries were observed to be enamel and enamel and dentine fractures. Conclusion: The overall pooled prevalence of TDI in individuals with special healthcare needs was 23.16% with 20.98% in males and 27.06% in females. Overjet >3 mm and inadequate lip coverage were found to be associated with a higher risk of TDI in all the categories of individuals with special healthcare needs except ADHD and ASD. Falls at home in cerebral palsy, falls while walking and self‐harm in ADHD and ASD, falls at home and collision in visual impairment, and unspecified falls in multiple disorders could be identified as the most common cause of TDI.

Background Several risk factors have been associated with early childhood caries (ECC). However, conclusive data are not available about the socio-demographic and behavioural factors which are associated with severe ECC (S-ECC). We assessed the severity and pattern of ECC in young children. We also looked for association of S-ECC with various sociobehavioural risk factors in a hospital-based setting. Methods We included 200 children, 1-6 years old, who reported with dental caries to a paediatric dental outpatient in a tertiary care hospital. Information about socio-demographics and various behavioural factors was recorded in a structured proforma using an interview method. The American Academy of Paediatric Dentistry (AAPD) criteria were used for categorizing children into ECC and severe ECC groups (S-ECC). Qualitative variables were analysed by chi-square test. Multiple logistic regression analysis was done to find the predictors of severe S-ECC. All statistical tests were done at a significance level of p<0.05. Results The majority of children (85%) had S-ECC and anterior-posterior (AP) caries pattern (77%). A significant association was found between the age of the child (p<0.001), absence of siblings (p=0.009), continuation of bottle feed or mother's milk till the age of reporting to the hospital (p=0.007), frequency of night-time feed (p=0.048) and S-ECC. Conclusions A continued habit of milk feed from bottle/mother till the time of dental visit seeking treatment and night time-feeds more than twice had a significant association with S-ECC.
