BACKGROUND The aims of this study were to (1) investigate to what extent the generic and condition specific (CS) forms of the oral impact of daily performance (OIDP) inventory discriminate between a group of patients with hypodontia and a group of patients having malocclusion, (2) assess the association of the generic and CS OIDP with severity and localisation of hypodontia, whilst adjusting fo...

The association between craniofacial morphology and congenitally missing teeth is at present unclear. The aims of this study were to investigate whether hypodontia is associated with changes in the sagittal skeletal profile and to identify putative relationships between the skeletal profile and the severity of hypodontia. In a cross-sectional analytical study, the craniofacial structure and pro...

BACKGROUND Genetic mutations that result in hypodontia also may be associated with abnormalities in other parts of the body. The authors conducted a study to establish the prevalence rates of hypodontia among subjects with epithelial ovarian cancer (EOC) and control subjects to explore possible genetic associations between these two phenotypes. METHODS The authors recruited 50 subjects with E...

Although taurodontism has been reported in many syndromes which also feature hypodontia, there have been no previous investigations on the prevalence of taurodontism in patients with hypodontia. Using a novel biometric method for the assessment of taurodontism, we found that 34.8% of 66 patients with hypodontia had at least one mandibular first permanent molar which showed taurodontism compared...

OBJECTIVES To compare tooth size between subjects with mild, moderate and severe hypodontia and a control group. MATERIAL AND METHODS The study comprised 120 patients with hypodontia divided into three groups of 40 mild (≤2 teeth congenitally missing), 40 moderate (3-5 teeth congenitally missing) and 40 severe (≥6 teeth congenitally missing) hypodontia; and 40 age and sex matched controls. To...

The partial absence of teeth germs is a hereditary or acquired congenital defect called hypodontia. The present report analyses and discusses hypodontia in permanent dentition on the basis of eleven clinical cases. In these, the hypodontia corresponded to mandibular central incisors, maxillary lateral incisors, maxillary canines, or maxillary and mandibular premolars and molars. All these cases...

The aim of this retrospective study was to identify general health problems as potential predisposing factors for hypodontia in a population of Japanese orthodontic patients. The study included 3683 individuals (1312 males and 2371 females, 13-42 years of age; mean, 23 years 7 months). Dental pantomograms (DPTs) were used to diagnose hypodontia. Health histories were obtained through a question...

Assessment of tooth morphology is an important part of the diagnosis and management of hypodontia patients. Several techniques have been used to analyze tooth form in hypodontia patients and these have shown smaller tooth dimensions and anomalous tooth shapes in patients with hypodontia when compared with controls. However, previous studies have mainly used 2D images and provided limited inform...
