Re-Establishing the Esthetics of Incisors in Patients with Molar Incisor Hypomineralisation.

The awareness of molar incisor hypomineralisation (MIH) has led to its increased clinical detection, consequently drawing more attention to its associated complications. This text offers an overview of the esthetic management of anterior teeth affected by MIH, a condition characterized by enamel defects that present significant cosmetic challenges. The focus is on the clinical presentation of MIH characteristics, considering the depth of lesions and the clinical aspects, and the treatment protocols available, despite a lack of extensive scientific evidence.

Orthodontic Analysis behind the Extraction of Hypomineralised First Molars.

This chapter will discuss the orthodontic perspective of extractions of compromised first permanent molars (cFPMs) due to hypomineralisation. The context behind the diagnosis of a poor prognosis of cFPM that would support the planning of extractions will be presented. In addition, the ideal timing for interceptive extraction of cFPM as well as the favorable and unfavorable orthodontic scenarios for extractions in the permanent dentition will be discussed.

Tooth movement toward alveolar bone grafting with rhBMP-2 in a child with unilateral cleft lip and palate: Case report with long-term follow-up.

The secondary alveolar bone grafting procedure is typically recommended during the late mixed dentition phase, prior to the eruption of the permanent canine, in patients with cleft lip and palate. The anatomical and functional adaptations observed in the grafted area allow spontaneous migration and eruption of the adjacent maxillary canine. An alveolar bone graft can be performed using autogenous bone or recombinant human bone morphogenetic protein-2 (rhBMP-2).

Maxillary arch dimensions in bilateral cleft lip and palate in the age 0-5 months.

This study evaluated the maxillary arch dimensions in BCLP and compared them with neonates without craniofacial anomalies.

Methods: This retrospective study was conducted in a tertiary cleft centre.

Automated Orientation and Registration of Cone-Beam Computed Tomography Scans.

Automated clinical decision support systems rely on accurate analysis of three-dimensional (3D) medical and dental images to assist clinicians in diagnosis, treatment planning, intervention, and assessment of growth and treatment effects. However, analyzing longitudinal 3D images requires standardized orientation and registration, which can be laborious and error-prone tasks dependent on structures of reference for registration. This paper proposes two novel tools to automatically perform the orientation and registration of 3D Cone-Beam Computed Tomography (CBCT) scans with high accuracy (<3° and <2mm of angular and linear errors when compared to expert clinicians).
