The association between orthodontic treatment need and maxillary incisor trauma, a retrospective clinical study.

Objectives: Identifying risk factors for dental trauma in children is important. The main aim of this retrospective study was to investigate the association between maxillary incisor trauma (MIT) and variables such as gender, malocclusion complexity, and orthodontic treatment need (OTN).

Study Design: ICON (Index of Complexity, Outcome and Need) scores were calculated in 502 schoolchildren (253 girls and 249 boys, aged 11-14-years).

Agreement between the index of complexity, outcome, and need and the dental and aesthetic components of the index of orthodontic treatment need.

Introduction: This was a cross-sectional study to investigate the agreement between assessments of orthodontic treatment need of the index of complexity, outcome, and need (ICON) and the index of orthodontic treatment need (IOTN).

Methods: Five hundred two subjects (253 girls, 249 boys; ages, 11-14 years) participated in this study, including a few who were wearing an orthodontic appliance (1 girl, 5 boys). ICON scores and the aesthetic (AC) and dental health components (DHC) of the IOTN were recorded in those not undergoing treatment.

An investigation into the association between facial profile and maxillary incisor trauma, a clinical non-radiographic study.

Objectives: To explore the association between maxillary incisor trauma (MIT) and facial skeletal forms (sagittal and vertical), overjet (OJ), lip coverage, and gender.

Subjects And Methods: Five hundred and two subjects (253 females and 249 males, aged 11-14 years) were examined. Sagittal (Class I, II or III) and vertical skeletal pattern (average, increased or decreased Frankfort-Mandibular Plane Angle (FMPA)) were recorded.

The relationship between the ICON index and the dental and aesthetic components of the IOTN index.

Aim: To determine the malocclusion complexity and orthodontic treatment need in urban Iranian schoolchildren using the Index of Complexity, Outcome, and Need (ICON) and the Index of Orthodontic Treatment Need (IOTN) and to also assess the relationship between these indices.

Methods: The study sample comprised 502 individuals (253 girls and 249 boys, 11 to 14 years of age), of whom one girl and five boys already had an orthodontic appliance at the time of the survey. In those individuals not wearing orthodontic appliances (n=496), the definitive treatment need (ICON>43) and compartments of the ICON were defined and compared between sexes.

Malocclusion and occlusal traits in an urban Iranian population. An epidemiological study of 11- to 14-year-old children.

The aim of this cross-sectional study was to determine the prevalence of malocclusions, occlusal traits, and their gender distribution in urban Iranian school children. Five hundred and two subjects (253 females and 249 males, aged 11-14 years) were examined. Molar relationship, overjet (OJ), overbite, midline deviation, crossbite, and crowding/spacing were recorded.
