The position of the lingula was determined relative to the anterior and posterior border of the ramus, mandibular notch, inferior border of the mandible, and mandibular plane. The mandibular angle was also recorded. In Vivo5 software was used to assess the images.Results: The average distance for all positional measurements was significantly greater in 14- to 18-year-old adolescents when compared with six- to nine-year-old children. In the oldest age group, the mandibular angle was significantly more acute. Significant differences in distances were noted bilaterally across all age groups in boys and girls for dista...

The study sample comprised 17 prepubertal subjects (mean age 11.2 years) with constricted maxillary arches. Total amount of expansion was 7 mm in all subjects. Multi-slice low-dose CT scans were taken at T0, T1, and T2. On axial CT scanned images a circle line corresponding to the palatal area was drawn and the area inside the circle registered at all three observation times. The area was measured in mm². Statistical comparisons were carried out with Friedman test with post-hoc tests (P<0.05). The palatal area showed a significant increase from T0 to T1 and from T0 to T2 as a consequence of the opening of the midpalatal suture after RME. Opening the midpalatal suture by using orthopedic forces allowed to extend the area of the maxilla...

Many authors have been trying to devise a clear definition or classification for ECC. The aim of this review was to inventory the prevalence of ECC and to seek a consensus regarding definition and diagnosis. Further attention was paid to the aetiological factors including the role of microrganisms. Finally, education, parenting and treatment procedures were discussed. For this review, epidemiological studies on caries prevalence in children aged between 0 and 36 months were compiled through a systematic approach using Medline. This clearly showed that ECC continues to be a serious public health problem and that there is a great variety of definitions and diagnoses used worldwide, reflected in the prevalence data. This review confirms the multicausal aetiology and the need for further research. The authors strongly support the recommend...

The aim of this study was to investigate the determining factors of oral health in CF homozygotes, CF heterozygotes and healthy controls. CF homozygotes had significantly the lowest caries experience, while CF heterozygotes had a borderline not significant higher caries experience than healthy controls. CF homozygotes also had significant lower Streptococcus mutans counts than both other groups. CF homozygotes also had significant less gingival bleeding, while no significant differences in plaque and calculus amount were found between the three groups. On behalf of oral hygiene habits, no significant differences were found between the three groups. CF homozygotes appeared to consume...

More research has been put into serum, when compared to saliva, although that is changing. More and more researchers are interested in the role of certain proteins or electrolytes in an oral disease process. Besides the purely laboratory research, practitioners are also interested in the bacterial colonisation of the oral fluids, especially in assessing a patient's caries risk. The use of bacterial chair-side tests illustrates this aspect of progression in oral health care. For the dental professional, saliva is an important ally in preventing dental caries and mucositis. The lubrication properties and antibacterial/antiviral function of saliva play an important role in the protection of the oral cavity. These aspects may be suppressed in some medically compromised patients. In those cases, the dental professional is faced with a challenge to solv...

Radiographical appearance may be confusing though. This study aimed to review the literature on SBCs and to map the SBC as shown in their respective papers. Methods: A Pubmed® search (1/9/2018 till 31/5/2019), mentioning SBC, was carried out. Included papers had to contain: patient’s age, gender and radiographs. Results: In total, 114 papers were found, but only 64 papers were retained, which contained 109 cases (95 males, 14 females). The patients’ ages ranged between 14 and 89 years old (mean age being 52 years). Male patients’ ages (N = 95) ranged from 14 to 89 years (mean age 52.3 years), whereas the females (N = 14) ages ranged between 22 and 68 (mean age 50.2 years). 28 combinations of locations of SBC were recorded. Only three lesions were located at the symphysis, six were bilateral, 55...
