The purpose of this study was to investigate the effect of biting pressure on first and second molar eruption, and to clarify that biting pressure may be one of factors influence to tooth eruption. The subjects were 103 patients, 57 (28 boys and 29 girls) were 5 years old, 46 children (23 boys and 23 girls) were 11 years old. Each patient's biting pressure was measured on the second deciduous molar at 5 years old, and on the first molar at 11 years old. The degree of first maxillary and mandibular molars at 5 years old was measured using lateral cephalometric radiogram analysis, and the degree of second maxillary and mandibular molars at 11 years old. Pearson's correlation coefficients were used to study the relationship between biting pressure and the degree of molar eruption. At 5 years old, a significant statistical negative correlation was observed between the biting pressure of the second deciduous molars and the degree of first mandibular molar eruption. But no significant statistical correlation was observed between the biting pressure of the second deciduous molars and the degree of first maxillary molar eruption. At 11 years old, a significant statistical negative correlation was observed between the biting pressure of the first molar and the degree of second mandibular molar eruption. But no significant statistical negative correlation was observed between the biting pressure of the first molar and the degree of second maxillary molar eruption. These results suggested that the biting force might promote mandibular posterior molar eruption.
