Analysis of the stomatognathic system functions and mastication muscles in children affected by molar hypomineralization (MH): a cross-sectional study.

Purpose: To analyze the functions of the stomatognathic system in children with or without molar-incisor hypomineralization (MIH).

Methods: For this cross-sectional study, 72 children aged 6-12 years were recruited and divided in two groups: with MIH (G1) and without MIH (G2). T-SCAN was used to verify the distribution of occlusal contacts, gnathodynamometer to measure maximum molar bite force, and Iowa Oral Pressure Instrument (IOPI) to assess the strength of facial expression muscles.

Comparison between intraoral scanning and direct visual analysis for the assessment of developmental defects of enamel.

Objective: To compare direct visual analysis (DVA) and intraoral scanning (IOS) for the assessment of developmental defects of the enamel (DDE).

Methods: Thirty-nine extracted permanent human teeth with DDE were selected by an experienced examiner and digitised using IOS. The scanning was recorded using the OBS Studio software parallel to the IOS software to obtain a coloured high-definition MP4 file of the process.

Association of dental hypersensitivity and anxiety in children with molar-incisor hypomineralisation (MIH).

Aim: The objective of this study was to investigate whether dental hypersensitivity and dental fear were linked to the presence and severity of MIH.

Methods: For this cross-sectional study, 1830 students between the ages of 6 and 12 years were recruited from four randomly selected schools. The Children's Fear Survey Schedule-Dental Subscale questionnaire was used to assess dental anxiety and fear.

Electromyographic analysis of the stomatognathic system of children with Molar-incisor hypomineralization.

Introduction: Molar-incisor hypomineralization (MIH) is a qualitative defect of dental enamel that affects one or more permanent first molars, with or without involvement of the incisor teeth. This condition leads to challenges to dental care and treatment planning.

Aim: Based on the hypothesis that children who have MIH possibly present alterations in postural and masticatory activities and considering the absence of studies investigating these parameters, the present study evaluated the functionality of the stomatognathic system considering the mentioned aspects.

Dentists' attitudes and practices toward evidence-based dentistry: a systematic review.

Introduction And Aims: Considering that attitudes toward evidence-based dentistry (EBD) may predict implementation behaviors, the objective of this systematic review was to synthesize and evaluate the existing evidence related to dentists' attitudes and practices toward EBD.

Methods: We included primary studies that collected information from interviews, questionnaires, or conversation sessions with dentists. The following sources were searched: Cochrane Central Register of Controlled Trials, Embase, PubMed, Scopus, and Web of Science, in addition to gray literature.

Streptococcus mutans adherence to conventional and self-ligating brackets: an in vitro study.

Introduction: Although self-ligating brackets presumably provide better hygiene conditions, no consensus has been reached so far.

Objective: Therefore, the objective of this study was to evaluate, in an in vitro experimental design, the adherence of Streptococcus mutans (SM) in self-ligating and conventional brackets of different manufacturers and ligature types.

Methods: Four commercial brands of maxillary premolar metal brackets were tested (Abzil®; Morelli®; 3M Unitek®; and GAC®).

Orthodontic mini-implants: clinical and peri-implant evaluation.

The study evaluated the clinical changes of orthodontic mini-implants (MI) inserted for the purpose of anchoring during orthodontic treatment. The null hypotheses were: 1-that there is no correlation between proximity of the MI to the root and peri-implantitis or mobility; 2-that peri-implantitis does not interfere with mobility; 3-that the pain is not related to mobility or peri-implantitis. Forty (40) patients were selected and the MI were evaluated for each patient.

Diagnostic sequence for early diagnosis of neurofibromatosis type 1 using NIH criteria.

Early diagnosis of neurofibromatosis is significant to start the multidisciplinary approach of this type of patient. This syndrome may be first identified in pediatric dental care. This study is about a 9-year-old patient who was diagnosed with neurofibromatosis type 1 from a plexiform neurofibroma displayed in the left hemi-maxilla.

Orodental Findings in Patients with Lacrimo-Auriculo-Dento-Digital Syndrome.

Lacrimo-auriculo-dento-digital syndrome (LADD) is a rare autosomal dominant disorder arising from heterozygous mutations in the genes encoding fibroblast growth factor receptors two and three and the gene encoding the fibroblast growth factor 10. The characteristics associated with LADD are mainly related with hypoplasia or aplasia of lacrimal and salivary ducts, low cup-shaped ears, sensorineural or conductive hearing loss, abnormalities of teeth, and anomalies of the hands and feet. The purpose of this paper is to describe a 13-year-old female patient with a history of a blocked tear duct, mild hearing loss, congenitally missing teeth, tauro- dontism, and malformation of the fingers who was referred for a dental evaluation.
