“…The Japanese-Brazilian group showed significantly greater anterior and overall ratios than Bolton standards. Other studies also reported significantly greater anterior ratio 8,7,13,24 and overall ratio 6,13,25 than Bolton standards for different populations.…”

“…Although some studies report that Bolton's ratios can be applied for different populations 10,11 , others claim the opposite 6-8,12,13 . Smith et al 13 (2014) also found significant differences for the anterior and overall ratios compared to Bolton's ratios in an Indian population. These studies highlight the need for population-specific standards for clinical assessments of tooth size ratios.…”

Objective: The aim of this study was to determine if Bolton's tooth size ratios can be applied to Mediterranean, Japanese and Japanese-Brazilian populations. Materials and methods: The sample comprised 90 pairs of dental casts of untreated individuals with normal occlusion, divided into 3 groups according to ethnical characteristics: White (30 Mediterranean descendant subjects, with a mean age of 13.64 years), Japanese (30 subjects with Japanese ancestry, with a mean age of 15.63 years) and Japanese-Brazilian (30 Japanese-Brazilian subjects, with a mean age of 13.96 years). A digital caliper was used to measure the maxillary and mandibular mesiodistal widths from first molar to first molar on each dental cast. The anterior and overall tooth size ratios were calculated. T test was applied for comparisons between Bolton standards and the ethnical groups for anterior and overall ratios. Results: Only the Japanese-Brazilian group showed significantly greater ratios than Bolton standards. Conclusion: It was concluded that Bolton's ratios are not applicable to the Japanese-Brazilian population. Therefore, it is suggested that Bolton's ratios may not be suitable for different populations.

“…Pro mnohé autory není otázka okluzních kontaktů při protruzním pohybu zajímavá, spíše se zabývají okluzními kontakty při pohybu laterotruzním, a tak tato oblast trpí nedostatkem nejen epidemiologických dat. Protruzní kontakty zkoumali Scaife a Holt [11], Gazit a Lieberman [4], Sadowsky a BeGole [9], Sadowsky a Polson [10], Ingervall, Hähner a Kessi [5], Al-Nimri, Bataneih, Abo-Farha [1], Sreekumar, Rupesh, Pradeep [12]. Někteří z nich okluzní kontakty také klasifikovali.…”

Abstract-Tooth extraction is a treatment of choice in the tooth size discrepancy cases in order to achieve appropriate alignment, angulation, and inclination of the teeth. The objective of this study was to determine the effect of premolar extraction on overall Bolton ratio in Class III malocclusion. Samples in this study consisted of 40 study models of subjects with Class III malocclusion that meets the inclusion criteria. Measurements were performed directly on 12 maxillary and mandibular teeth in study model using an electronic digital caliper with accuracy 0.01 mm. Furthermore, the initial overall Bolton ratio was calculated on the whole samples and continued with several hypothetical extractions. After that, the calculation of the overall Bolton ratio in the fifth combination of premolar extraction was done and the results were statistically tested. The results showed that the initial overall Bolton ratio consisted of 5 subjects (12.5%) with small overall Bolton ratio, 24 subjects (60%) with normal overall Bolton ratio, and 11 subjects (27.5%) with large overall Bolton ratio. Wilcoxon test showed the effect of premolar tooth extractions on overall Bolton ratio in Class III malocclusion (p=0.001). Overall Bolton ratio decreased significantly after the extraction of the premolars in all hypothetical extractions, where normal Bolton ratio was observed in the combination of upper first premolar and lower second premolar extractions. As the conclusion, premolar tooth extraction affects the overall Bolton ratio in Class III malocclusion.
