OBJECTIVE To evaluate the relationship between the stages of dental formation and the timing of eruption of mandibular second premolars. MATERIALS AND METHODS The sample comprised panoramic radiographs of 25 children, 7 to 12 years old, observed by space supervision during development of dentition. The initial radiograph (T1) was taken in the mixed dentition period and the progress radiograph...

Long-term stability after orthodontic treatment is highly desirable, especially alignment of the mandibular anterior dentition as might be quantified by the irregularity index. Post orthodontic treatment stability is a vexing problem, and without permanent fixed retention, this issue has been a problem without a solution until recently. In 2014, long term stability of the mandibular anterior se...

Background: Smoking has been associated with periodontal disease severity and is considered a risk factor for its development. The objective of this study was to evaluate the prevalence and severity of periodontal destruction in mandibular molar teeth of adult smokers and non-smokers. Materials and Methods: The study group consisted of 100 subjects (50 smokers & 50 non-smokers) age range (30-60...

Introdouction: The purpose of the present study was to determine the possible relationship between gonial angle size and three mandibular morphometric parameters, namely, panoramic mandibular index (PMI), mandibular cortical width (MCW), and antegonial notch depth (AD), in digital panoramic radiographs. Materials and methods: PMI, MCW, and AD were calculated in digital panoramic radiographs of...

OBJECTIVE The aims of this study were: to investigate the relationship between mandibular canine calcification stages and skeletal maturity; and to evaluate whether the mandibular canine calcification stages may be used as a reliable diagnostic tool for skeletal maturity assessment. MATERIALS AND METHODS This study included 151 subjects: 81 females and 70 males, with ages ranging from 9 to 16...

STUDY OBJECTIVE To evaluate the tolerability and to find predictors of treatment success for an individually adjusted, one-piece mandibular advancement device in patients with snoring and obstructive sleep apnea. DESIGN Prospective study. SETTING Departments of Respiratory Medicine and Orthodontics, Umeå University. PATIENTS Six hundred nineteen of 630 patients (98%), who consecutively re...

objective: the aim of this cross-sectional analytic study was to evaluate the diagnostic efficacy of panoramic-based indices of the mandible (mental index-mi, mandibular cortical index-mci and panoramic mandibular index-pmi) and to determine their correlation with bone mineral density (bmd) of the femoral neck and lumbar vertebrae (l2-l4) in order to assess the possibility of using these parame...

BACKGROUND We describe the case of a 16-year-old female patient with micrognathia, temporomandibular joint (TMJ) ankylosis, and obstructive sleep apnea, who was treated with mandibular distraction osteogenesis (DO) combined with sliding genioplasty, using skeletal anchorage. CASE PRESENTATION We first performed interpositional arthroplasty, in which an interposition of fascia temporalis and s...
