Mesiodistal size of deciduous teeth in subjects with unilateral cleft lip and palate

Abstract

The aim of this study was to investigate whether there was an association between presence of a cleft and reduced size of deciduous tooth on the cleft side. In this investigation, 58 study models of patients with unilateral cleft lip and palate with deciduous dentition were analyzed. The largest mesiodistal dimension of deciduous teeth was measured by a sliding caliper. The size of the same teeth on the side of the cleft and on the non-cleft side was compared. The results of the investigation were statistically analyzed. A difference between the genders was found. In the sample of boys the lateral deciduous incisor and the second deciduous molars on the cleft side were smaller than those on the non-cleft side, while in girls the central and lateral deciduous incisors were smaller on the cleft side than on the non-cleft side. It was concluded that the presence of a unilateral cleft lip and palate was associated with smaller tooth size.

Early post‐natal development of the mandibular permanent first molar in infants with unilateral complete cleft lip and palate

“…1,31 Dental size in cleft children has been investigated in a number of studies including children with unilateral and bilateral cleft lip and palate (e.g., [9][10][11]. However, except for a single study on 5-year-old children, 12 all previous studies have described older age groups. Furthermore, all previous studies on tooth size in children with cleft lip and palate have used plaster casts to obtain tooth measures.…”

“…In the literature, a relative limited number of studies have investigated tooth size in children with clefts. [6][7][8][9][10][11][12][13][14][15][16][17][18][19] All these studies agree that the anterior teeth are smaller in children with CLP, and a metaanalysis 18 shows that also the posterior teeth (molars) are smaller.…”

Early postnatal development of the mandibular permanent first molar in infants with isolated cleft palate

“…12,19). Except for a single study on 5-year-old children, 26 all previous studies have described older age groups. Furthermore, all previous studies on tooth size in children with clefts have used plaster casts to obtain tooth measures; however, the production of plaster casts may result in distortion of tooth size and form.…”

Expanding the cleft phenotype: the dental characteristics of unaffected parents of Australian children with non‐syndromic cleft lip and palate

“…Individuals with clefts of the lip and/or palate have been reported to have an increased number of dental anomalies 6,[9][10][11][12] . The anomalies most commonly described include tooth agenesis or hypodontia 11 , extra or supernumerary teeth 10 , enamel defects 13,14 , and microdontia 15,16 . The rationale is that if individuals with a cleft have an increased prevalence of dental anomalies, it is possible that their unaffected relatives may be similarly affected.…”
