“…This is consistent with the results of other studies [2][3][4][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] were the thumb and finger also exhibited the highest frequency and were most implicated in the formation of an anterior open bite. This is also in agreement with studies by Onyeaso Other oral habits like the tongue [1][2][3][24][25][26] , pacifier 1, 30-32, and lip and cheek sucking 2,10 have been implicated in the aetiology of an anterior open bite.…”

“…Definitions on the aetiology and prevalence of anterior open bite vary and a review of the literature shows various aetiological classifications 5,[7][8][9][10][11] which could also be pathologic, neurologic or iatrogenic [8][9][10][11] .Others include a clinical classification in which the open bite could be dental [3][4][5][6][7][8][9] , asymmetrical if it affects only one segment, or symmetrical if it affects both segments of the jaws and is seen in the majority of children in the transitional and mixed dentition stage 1,3,4,8,9 Prevalence rates for anterior open bite have ranged from 2 to8 percent from other studies in pre-school children 10,13,14 and from 1.5 to 16.5 percent in older children 1,[15][16][17][18][19] . , they may or may not exhibit retroclined incisors, a narrow "v" shaped palatal vault [5][6][7][8] and atypical phonation affecting the production of the following phonetic sounds: /t/, /d/, /n/, /l/, /r/ .…”

Background: Anterior open bite is said to exist when there is an actual vertical gap between the upper and lower incisors with the teeth in centric occlusion. This could occur in the anterior or posterior region, and may be attributed to the supra eruption of the posterior teeth or the infra eruption of the anterior teeth and it is common in both adults and children. Objective: To evaluate the prevalence of anterior open bite (AOB) in 2 to 5 -year -old children and the aetiological factors responsible for it. Methods: The study group comprised 1031 children (429 boys and 602 girls) between the ages of 2 to 5-years, who were examined for the presence of AOB and the relationship with various oral habits. Results: AOB was present in 29 (2.8%) of the subjects. Sucking habits were observed in 267 (25.9%) children. Only 29(10.9%) of the children with sucking habits had an AOB which was asymmetric in 20 (7.5%) and symmetric in 9 (3.4%). The asymmetric AOB was significantly higher in children with thumb sucking habits than in finger suckers (P<0.05). There was no significant difference between frequency, duration of sucking habits and AOB. The 4-year olds showed a significant difference in the number of children with AOB (P<0.05). Sucking habits of 1-2 hours and duration of 24 to 60 months exhibited the highest prevalence of an AOB in 13 (44.8%) and 17 (58.6%)children respectively. Conclusion: The prevalence of AOB in this study is 2.8%. Thumb sucking is the most important aetiological factor in the formation of an AOB in 2 to 5-year-old children.

None of the children examined had gone for routine dental check-ups before except for the 62(12.6%) who had previous dental consultations due to toothaches. Conclusion: Oral habits especially digit sucking needing management was revealed by this study and none of them had been to a dentist for help. This suggests that there is need to intensify oral health education in our environment, targeted at both parents and school children to enable them benefit from interceptive orthodontic care which has numerous advantages.

“…Finger-sucking is a common oral habit, and was observed by Kurosu et al 11) in 28.0% of children aged 1-14 years, by Kamiyama et al 6) in 23.3% of children aged 2-6 years, and by Abe et al 1) in 18.9% of children aged 0-12 years. Finger-sucking often exerts adverse effects on dentition and occlusion 4,5,[8][9][10]12,13,15,18,20,21) , and open bite, maxillary protraction, narrowing of the maxillary dentition, molar crossbite, posteroinferior displacement of the mandible, and crowding of the mandibular incisors may be caused by this habit 5,7,8,11,15,21,23) . Abnormal muscular activities in the lips and tongue have been reported in association with such morphological changes, complicating or exacerbating malocclusion.…”

Measurement of the pressure applied to the anterior region of the palate and incisor region of the mandible during thumb-sucking was carried out 3 female children. A polyethylene bag embedded with a high-sensitivity small pressure sensor was fixed on the ventral side of the thumb so that the baroreceptor could be interposed between the thumb and palate during thumb-sucking. The children were allowed to perform habitual thumb-sucking, and the resulting pressure signals were detected with a high-response dynamic strainmeter and recorded. Measured peak pressures were about 2-4.5kgw, with large individual variation, and waveform patterns also varied. Characteristics of thumbsucking habits and thumb-sucking pressure were related to malocclusion. Measurement of thumb-sucking pressure is believed to be effective for assessment of the qualitative relationship between thumb-sucking and malocclusion.
