The orthodontic miniscrew (TADs) is a device that is fixed into bone in the short term for the purpose of enhancing orthodontic anchorage. The aim of our study was to investigate the structural and surface properties of recovered TADs after orthodontic treatment, and compare them to new TADs. TADs (n = 15) from the same manufacturer (Absoanchor; Dentos, Daegu, Korea) were assessed; n = 10 were recovered from patients after orthodontic treatment and n = 5 were new.

Even though CBCT is considered a low dose radiological examination, ionizing radiation is a known human carcinogenic factor. Furthermore, biological effects are more important in young patients because of their higher radiosensitivity.

Saliva, because of the ease of collection, could be valuable in studying low-dose IR effects by means of surface-enhanced Raman spectroscopy (SERS). The objective of our study was to compare the salivary SER spectra recorded before and after low-dose IR exposure in the case of pediatric patients (PP).

Facial asymmetries have an important impact on the cranio-facial structures morphology, being the result of the genetic, environmental and dysfunctional factors and their impact on the dento-maxillary complex. Asymmetries can be identified in all craniofacial structures, including the upper airway cavities. Craniofacial asymmetries can influence general growth and development by altering the respiratory function.

Following clinical examination, it is important for the dental practitioner to establish whether FP was caused by injury to the facial nerve, and to focus on the site of the lesion and potential risk factors. The risks of dental treatment in a patient with FP should also be assessed.

Unlabelled: Anchorage represents a great issue that challenged orthodontists all over the years. Nowadays, with the use of microimplants, it has become possible even to induce complex teeth movements.
Aim: To present a clinical case in which mesialisation of upper second molars was performed by the means of using miniimplants.
