The relationship between tooth size discrepancy and archform classification in orthodontic patients.

Background: To determine the relationship between clinically significant tooth size discrepancies (TSD) and archform classification in orthodontic patients.

Material And Methods: Eighty teeth with artificial white spot lesions were randomly divided into four groups: (A) distilled and deionized water, (B) Nd:YAG laser, (C) CPP-ACP crème, & (D) CPP-ACP plus laser. SMH was measured using Vickers diamond indenter in Vickers Hardness Number (VHN).

Tooth size discrepancies in Irish orthodontic patients among different malocclusion groups.

Objective: To determine the prevalence of tooth size discrepancies (TSDs) in an Irish orthodontic population among different malocclusion groups.

Materials And Methods: From 850 pretreatment sets of orthodontic models at a university clinic, 240 were selected with 30 female and 30 male sets for each malocclusion (Class I, Class II division 1, Class II division 2, and Class III). Digital models were produced, and the mesial and distal contact points were digitized to calculate overall and anterior tooth size ratios.
