“…The sample consisted of orthodontic treatment patients, with either normal occlusion; class I with crowding or cross bite, or malocclusion class II or III. Crowding has been associated with enlarged crown size [69][70][71][72] or normal crown size with reduced dental arch length [73]. Malocclusion classes II and III in addition have also been found to be associated with enlarged [74] and nonenlarged crown sizes [75].…”

“…The accomplishment of a serial extraction protocol affords early correction of tooth size/arch length discrepancy, improvement of self-esteem, better oral hygiene, a better chewing function, and a reduction of the period of corrective orthodontic treatment 3,19 . Despite the positive effects demonstrated by this treatment protocol, some disadvantages may be pointed out, such as the need of specialized long-term follow-up, possible remaining spaces in the area of the extracted teeth, retroclination of the incisors, overbite, increase of both the Spee curve and the profile concavity, possibility of tongue interposition, and periodontal problems.…”

“…The correction of the real discrepancy between the tooth mass and the osseous base is performed by specific extractions as from the beginning of the mixed dentition, following a predetermined strategic sequence that allows the spontaneous alignment of the permanent teeth 6 . The best stage for diagnosing definitive primary crowding, and for initiating the serial extraction protocol is, undoubtedly, the stage when the permanent incisors erupt into the oral cavity 5,7,8,16,19 . This protocol is indicated for Class I malocclusions with negative tooth/bone discrepancy, or when there is no need for dental arch expansion, or still, should the expansion be necessary, when it is not sufficient to result in a tooth size/arch length compatibility 6,14 .…”

This paper reports a case treated by a serial extraction program at the mixed dentition stage followed by a corrective orthodontic treatment, with a long-term follow-up period. Twenty years after the interceptive treatment, a harmonious face was observed along with treatment stability in the anterior posterior direction, deep overbite (which has been mentioned as a disadvantage of the serial extraction program), and a small relapse of anterior tooth crowding. All these conditions have been regarded as normal occurrences for most orthodontic treatments with a long-term follow-up period. This case report demonstrated that the establishment of a serial extraction protocol determined relevant esthetic changes that afforded an improvement of the patient's self-esteem, with a positive social impact. Furthermore, the low cost of this protocol permits the use of this therapy with underprivileged populations. It is important to emphasize that an early correction of tooth crowding by this protocol does not guarantee stability, but small relapses do not invalidate its accomplishment.

“…(6,7) So, space analysis should be done accurately before any orthodontic treatment, (8) based on these calculation, therapeutic procedures can be introduced ranging from resolving slight incisor crowding by simple methods to more complex mechanisms of space regaining or even serial extractions. (9,10) It has been established that the degree of tooth sizearch length discrepancy increase from the deciduous dentition to the mixed dentition and from the mixed dentition to the permanent dentition.

Aims: To estimate multiple regression equation on (88) subjects (48 females and 40 males),for predicting the widths of crowns of unerupted canine and premolar for both jaws and both genders. The subjects had normal class I molar relationship with full permanent dentition. Materials and methods: Plaster models of (88) subjects (48 females and 40 males ).Mesiodistal diameter (MMD) and vestibulooral diameter (VOD) of the crown of cental incisor, lateral incisor,canine,premolars and first molar( I1,I2,C both P1 and P2, and M1) on both sides in both jaws were measured. Multiple regression equations and correlation coefficients between the predictors( central incisor,lateral incisor and first molar) and the criteria variables (canine and premolars) were calculated. The data were analyzed by computerized statistical program SPSS. Results: Gradual regression equations were derived on the basis of measurement result ,by using three to five predictors to predict the sums of width of crown of unerupted canine and premolars using separated equations for both jaws and both genders (i.e four multiple regression equations were prepared).The coefficients of multiple correlations regarding gender and jaws ranged between 0.70-0.79.Conclusions: Establish regression equations, which would give satisfactory correlation coefficient regarding the gender and the jaw varied from 0.70-0.79.
