This cross-sectional study investigated the relationship between digit-sucking habit and emotional stress measured by the urinary catecholamines in 314 children, boys and girls, ages six to eight years. The digit-sucking habit was recorded by an interview. A twenty-four hour urine sample was collected for each subject and a representative sample was analyzed by the HPLC technique to assay the catecholamine content. Socioeconomic factors were recorded by a questionnaire distributed to the parents. The logistic multiple-regression analysis was used to test the impact of catecholamines and other related factors on the presence of a digit-sucking habit. The results showed that emotional stress measured by the urinary catecholamines did not have a significant effect on the presence of a digit-sucking habit. Of the socioeconomic factors, father's education had a significant negative effect on the presence of the habit. The evidence provided by this investigation cannot support the view of psychoanalytic theory that continuation of the habit beyond the early childhood is due to emotional stress.

Oral habits such as nail biting, thumb/digit sucking and teeth grinding could be harmful, and may lead to teeth misalignment, anterior open bite, protruded or flared upper anterior teeth especially if they persist into adolescence. Such orofacial dysfunction may result to impairment of the Oral Health Related Quality of Life (OHRQoL) of an individual. The extent to which oral habits affect the major domains of the self-reported outcomes remains understudied especially during adolescence, a unique period of growth, where there is increased aesthetic desire, increased self-awareness, and unique social and psychological needs.

Background: Mastication is important for breaking down food, aiding swallowing and nutrients absorption, and is therefore fundamental to a child's development. Studies have shown poor masticatory function to be associated with younger age and presence of caries. However, studies of the association between masticatory function and malocclusion yielded contradictory results.

Background: Digit sucking is a common oral habit among many children, which involves placing the thumb/finger into the mouth, which can cause malocclusion in mixed and permanent dentition.
Aim: To evaluate the efficacy of the RURS elbow guard in the management of thumb-sucking habits in children with intellectual disabilities and those without in terms of the mean duration of appliance therapy. The secondary objective was to compare the RURS elbow guard with an intraoral crib in healthy children (without intellectual disabilities) to manage the habit of thumb-sucking.

Digit sucking and tongue thrusting are parafunctional habits that are commonly observed and are recognized as major etiological factors in the development of dental malocclusion. Treatment for these oral habits typically involves removal of the etiology, retraining exercises, and use of mechanical restraining appliances. A 13-year-old male patient reported a complaint of forwardly placed upper front teeth.
