Autistic children like soft and sweetenedfood. A wide spectrum of medical, psychologicaland behavioural symptoms makes dental caredifficult in them. Many studies have found no or littledifferences in the caries status betweenautistic children and normal children therebynecessitating the need to assess theprotective role of saliva.
Most psychiatric disorders are associated withincreased oxidative stress. It shows, temper tantrums, hyperactivity, selfinjurious behaviour and inability to expressthemselves and these increases the stresslevels and alter the antioxidant levels The need to evaluate the oral health status,salivary pH and salivary total antioxidantconcentration of these children.
Study groups : Medium functioning (IQ:50-70)Low functioning (IQ<50) Control group : siblings of these children The un-stimulated whole saliva samples werecollected 9-10 am from both group Oral health and treatment needs :OHI-S Dentition status and treatment needs : WHOoral health assessment form. The salivary total anti-oxidant level :spectrophotometer , PH : pH indicating paper
66/101 autistic children had caries. 74/101 autistic children had mixed dentition 31/74 children had dental caries
Incidence of dental caries in autistic childrenand siblings is non significant. Salivary TAC gives an indication to thesusceptibility of oral disease. Autistic children : 8.14 micrograms/ml Siblings : 43.31 micrograms/ml Emotional and psychological stress increasethe bodily concentration of oxidizingsubstances, such as ROS, free radicalsdecreased salivary antioxidant levels
Parafunctional habits such as thumbsucking, mouth breathing and tonguethrusting lower antioxidant levels Perioral hypotonic musculature makes themanatomical mouth breathers, gingivitis Low functioning group has lowest salivaryTAC dute to more severely compromisedability, stressful conditions.
Similar dental caries status was observed inchildren with autism and their healthy normalsiblings. Oral hygiene was poor in children with autism. Salivary TAC was significantly reduced inautistic children than healthy counterparts.
