(32) If sensory hypersensitivity is not addressed, it may develop into facial or oral defensiveness
, which is a conditioned response to stimuli that is perceived to be unpleasant by the child.
Conditions assessed were bacterial plaque, gingivitis, dental caries, restorations, bruxism, delayed eruption/missing teeth, oral infection, developmental anomalies, injuries, occlusion, salivary flow, and oral defensiveness.
Due to the increased incidence of oral defensiveness in children with an ASD, plaque accumulation was high, at 85% for all groups studied.
4) higher level of oral defensiveness in younger children as compared to older children
Oral Defensiveness: Intense sensitivity or overreaction to certain tastes, textures, temperatures of food, or touch in or around the mouth.
Some stimuli may not be perceived at all, for example a nipple is presented but no suck occurs, as if the volume button for the mouth has been turned to "low." Other stimuli may elicit too great a response for the amount of stimuli presented, for example a light touch to the lip may result in excessive gagging, as if the volume button has been set on "high." These situations are known as "oral defensiveness
There were 12 categories (ie, bacterial plaque, gingivitis, caries, restorations, bruxism, malocclusion, delayed eruption/missing teeth, infections, developmental anomalies, salivary flow, injuries, and oral defensiveness) assessed clinically using the evaluation criteria shown in Appendix A Appendix A part 2.
In addition, oral defensiveness was scored using an 8-point ordinal scale that identified the level of cooperation exhibited during the oral assessment.
In addition to analyses found in the tables, frequencies associated with the levels of oral defensiveness are presented below.
Considering the high incidence of oral defensiveness, one would expect the large amount of plaque accumulation found in children with an ASD.
