OBJECTIVES It is recommended that fissure sealants should be placed within four years after eruption. Due to considerable variations in the eruption times of molar teeth, this recommendation is of limited value from a public health perspective. This study, therefore, sought to provide empirical support for a public health fissure sealant placement timeframe protocol. METHODS The first and sec...

Ectopically erupted tooth is a rare disease, indicating that a tooth erupts into regions other than the oral cavity. We present a case of an ectopic maxillary third molar tooth in the external acoustic meatus, and discuss the diagnosis and treatment of this entity.

Because of clinical signs and symptoms, a diagnosis of pericoronitis in a partially erupted, partially impacted first molar was made. A more thorough diagnosis was made with the help of a periapical radiograph that showed caries and thus revealed an irreversible pulpitis. Appropriate treatment was the result.

OBJECTIVES The purpose of this study was to determine the incidence and clinical symptoms associated with sharp mandibular bone irregularities (SMBI) after lower third molar extraction and to identify possible risk factors for this complication. STUDY DESIGN A mixed study design was used. A retrospective cohort study of 1432 lower third molar extractions was done to determine the incidence of...

The first permanent molar as the first permanent tooth in the mouth and with a general insufficient oral hygiene of the children, is commonly subject to significant compromise which may arise due to caries or endodontic complication, or from developmental anomalies such as hypoplasia. Compromised teeth with questionable prognosis may result in shortand long-term clinical dilemmas. The aim of th...

objective: attempts to treat class ii malocclusions without extraction in non-compliant patients have led to utilization of intraoral molar distalizing appliances. the purpose of this study was to investigate dental and skeletal effects of bonded molar distalizer (bmd) which is a simple molar distalizing appliance. materials and methods: sixteen patients (12 girls, four boys) with bilateral hal...

Ankylosis is a condition frequently associated with primary molars, wherein the ankylosed primary teeth remain in a fixed position, while the adjacent teeth continue to erupt, moving occlusally. In this case report, a five-year-old boy, who had a retained and submerged left lower second primary molar, was presented. Luxation of ankylosed primary molar was considered as a treatment approach. Aft...

OBJECTIVE This study aimed to (1) evaluate the effects of maxillary second and third molar eruption status on the distalization of first molars with a modified palatal anchorage plate (MPAP), and (2) compare the results to the outcomes of the use of a pendulum and that of a headgear using three-dimensional finite element analysis. METHODS Three eruption stages were established: an erupting se...

T impaction of lower third molars is a common clinical finding, with a prevalence between 9.5% and 39% among different populations.1 Previous studies have indicated that normal eruption of lower third molars may be facilitated by extraction of the premolars before orthodontic treatment.2 Nonextraction therapy has been associated with more “abnormal” eruption of lower third molars compared to ex...

Introdouction: Impacted and partially erupted third molars can cause various symptoms and pathologies. The aim of this study was to determine the association between commonly observed pathological conditions and the impaction depth of lower third molar teeth. Materials and methods: In this retrospective study, 370 panoramic radiographs including 724 lower third molars were evaluated to asses...
