Abstract
Background: Oral health is a vital component of overall health, which affects positively on individual’s quality of life. chronic kidney diseases have become worldwide public health problems with a tendency for annual progression especially in pediatric nephrology during the last two decades.The aim: Evaluation of oral health status in children undergoing hemodialysis and kidney transplantation. Materials and Methods: This case control study was conducted on 250 children aged 6-18 years old, divided to 2 groups A (6-12) and B (>12) years old. Number of 100children undergoing hemodialysis was selected from Pediatric Nephrology clinic. Other 50 children undergoing kidney transplantation was selected from Mansoura Urology and Nephrology Center. In addition to 100 healthy children as a control group were selected from governmental schools in Mansoura city. All groups were examined and the oral health status of each patient was evaluated based on a questionnaire, DMFT index, dft index, PMA index, modified DDE index and OHIS index. Un-stimulated salivary flow rate and PH were also measured. Data was collected and statistically analyzed. Results: The study results revealed that there was lowering in caries prevalence, 55% in hemodialysis and 54% in transplantation group compared to 77% in control group (P-value 0.002). Regarding to age, there was statistical significant difference in caries prevalence. For gingival condition, there was significant difference in median PMA in both age groups. Concerning gender, females in transplantation group has higher median PMA than males (P-value 0.024). For oral hygiene condition, there was statistical significant difference in median OHIS at age >12 years old (P-value < 0.001) with no significant difference in gender. The prevalence of developmental enamel defects was 41% in hemodialysis group and 58% in transplantation group in comparison to 11% in control group (P-value < 0.001). Regarding to salivary flow rate and salivary PH there was significant difference between the studied groups (P value= 0.029), (P value<0.001) respectively. Conclusions: In children undergoing hemodialysis and kidney transplantation lowering in caries prevalence, increasing incidence of gingival inflammation, poor oral hygiene and increasing calculus deposition in addition to increase prevalence of enamel developmental defects were reported. The highest prevalence of developmental defects was recorded in transplantation group. Furthermore, there were decreasing un-stimulated salivary flow rate in children undergoing kidney transplantation. However, increasing buffering capacity of saliva was recorded in children undergoing hemodialysis and kidney transplantation.
