Digit sucking
• Gellin
It is placement of thumb or one or more fingers in varying depths into the mouth.

Common in infants23%to46% of children aged 1 to4years(Infante,1976;larson&dahin,1985.)
Develops ‐Between birth and 3 months of ageintensity increases ‐till 7 months and then declines.
Discontinue the habit by 3‐4 years of age.(Friman&Schmitt,1989;Traisman& Traisman,1958)
continues after 4 yrs ‐ greater risk for dental malocclusion (Friman&Schmit1987)digital deformities(Reid&Price,1984)speech difficulties(Luke&Howard,1983)

Theories of thumb sucking
• Psychosexual/ psychoanalytical theory ‐S freud 1905 ‐ arise from inherent psychosexual drive
• Learning theory – Davidson 1967 – adaptive response
• Oral drive theory – Sears and wise 1982 –prolongation of nursing strengthens the oral drive.
• Benjamin’s theory: rooting reflex

Causes
Parent’s occupation (Poporich and thomson 1973)
Working motherNo of siblingsSocial adjustments to stress (miltenberger, long,Rapp, Lumley and Elliot 1998)Feeding practices
(Levy 1928) low duration breast feeding ‐more incidence
( Karjalainen, Ronning, Lapinleimu, Simell.‐ 1999)Early introduction of bottle feeding interfere development of alveolar ridges and hard palate ‐ posterior cross bite.

• Schneider, 1982 ‐Tongue thrust is a forward placement of the tongue between the anterior teeth and against the lower lip during swallowing
• Norton and Gellin defined tongue thrust "as a condition in which the tongue protrudes between the anterior or posterior teeth during swallowing with or without affecting tooth position
