Effects on Tooth Position of a Soother With Especially Thin Teat Neck - A Randomised Clinical Study

Dr. Yvonne Wagner


Background

Sucking is a basic need for babies. Worldwide, 60 to 80% of young children use a soother. It is used to calm, for help going to sleep and helps protect against SIDS. Ideally, weaning off non-nutritive sucking with a soother should take place between the 24th and 36th month of life to prevent jaw and tooth misalignment. Prolonged and intensive use of soothers can lead to undesirable developments such as an anterior open bite, increased overbite (overjet) and cross bite.

In 2009, an innovative soother with an especially thin teat neck (MAM Perfect) was developed. Compared to 64 conventional soothers it is on average 60% thinner and 4 times more flexible* (Wild Hi-Precision Institut, Vienna University Dental Clinic). This soother should allow children to suck, minimise the known risks and promote healthy oral, tooth and jaw development. 

Study design

The randomised clinical study was conducted at the Jena University Clinic for Preventive and Paediatric Dentistry. The goal was to evaluate the effect of switching from a conventional soother to the MAM Perfect on malocclusions in the primary dentition.

For the study, 86 children between the ages of 16 and 24 months who already exhibited a soother related malocclusion such as an anterior open bite or enlarged overbite were recruited. They were randomly assigned to 3 groups. Group I switched to the MAM Perfect. Group II continued to use their regular soothers while the children in Group III should wean off the soother during the study period. Follow up examinations were conducted after 3, 6, 9 and 12 months by 2 calibrated dentists, of which one was blinded, meaning he did not know which group the children belonged to. 

Results

The results show significant differences between the 3 groups in terms of horizontal and vertical overbite. The comparison between Groups I and II regarding the degree of horizontal overbite and anterior open bite shows statistically significant benefits of the special soother over a conventional soother. The children in Group III, who had to have weaned of the soother for at least 3 months, showed the best results. It can be confirmed then, that after weaning off a soother, a so called spontaneous healing and self-correction occurs. Nevertheless, weaning is often the most difficult option. 6 children in the study could not be successfully weaned off the soother and another 3 children started thumb sucking. In summary it can be said that the soother with especially thin teat neck is a good alternative and reduces the risk of developing a malocclusion in the primary dentition
