OBJECTIVE To determine the prevalence and severity of occlusal problems in populations at the ages of deciduous and permanent dentition and to carry out a meta-analysis to estimate the weighted odds ratio for occlusal problems comparing both groups. METHODS Data of a probabilistic sample (n=985) of schoolchildren aged 5 and 12 from an epidemiological study in the municipality of São Paulo, Br...

Based on this literature review, early orthodontic treatment of unilateral posterior crossbites with mandibular shifts is recommended. Treatment success is high if it is started early. Evidence that crossbites are not self-correcting, have some association with temporomandibular disorders and cause skeletal, dental and muscle adaptation provides further rationale for early treatment. It can be ...

Anterior crossbite is the term used to describe an abnormal labiolingual relationship between one or more maxillary and mandibular incisor teeth. Different techniques have been used to correct anterior crossbite. This paper describes the use of Modified Essix appliance for the management of anterior crossbite in children in early mixed dentition. The case presented here demonstrates an anterior...

Supernumerary teeth which occur both in the primary and the permanent dentition are seen more frequently in the permanent dentition causing a variety of pathological disturbances. Presented herewith is a case report of a patient with a mesiodens which had caused flaring of the maxillary central incisors and impeded normal eruption of the maxillary lateral incisors. Extraction of the mesiodens w...

Anterior crossbite is the term used to describe an abnormal labiolingual relationship between one or more maxillary and mandibular incisor teeth. Different techniques have been used to correct anterior crossbite. This paper describes the use of bonded resin-composite slopes for the management of anterior crossbite in children in early mixed dentition.In each of the cases presented here, dental ...

It is often very difficult to replant avulsed teeth in the deciduous and mixed dentition when the cortical bone is fractured and there are no adjacent teeth for anchorage. In this article, we describe the management of avulsed maxillary incisors in a 7-year-old boy. The avulsed teeth could be successfully repositioned by intra-alveolar transplantation using the 180° rotation (buccolingual rever...

Supernumerary teeth are considered to be one of the most significant dental anomalies affecting the primary and early mixed dentition and may cause a variety of pathological disturbances to the developing permanent dentition. Early diagnosis and prompt treatment is necessary for prevention of deleterious effects on dentoalveolar structures. However, the time of intervention is the most crucial ...

The aim of this study was to evaluate the effects of the mandibular protraction appliance (MPA) for treating mild to moderate Class II malocclusion at different stages of dentofacial development. Lateral radiographs were evaluated before (T0) and at the end (T1) of orthodontic treatment with fixed appliance associated with MPA. Sixty-five consecutively treated patients were divided according to...

Background. This paper reports a case with end-on-molar relation with maxillary anterior teeth proclination, lower anterior teeth crowding, and deep bite. The case was successfully treated in a short span. Clinically significant improvement in the dimensions of the maxillary and mandibular dental arch forms and sufficient space for the eruption of permanent teeth was observed. Conclusion. There...

The purpose of this study was to evaluate the transverse and vertical dimensions of the palate of children with allergic rhinitis (AR). There was no significant difference for intermolar and intercanine distances between two groups in primary and mixed dentitions. Palate depth in children with allergic rhinitis was statistically more than in children without any respiratory disease. Cross bite ...
