Facial Growth: Does It Play A Role In Long-Term Stability Of Orthodontic Treatment?, Ib Leth Nielsen

Taiwanese Journal of Orthodontics

Following orthodontic treatment there is usually a period of retention to maintain the treatment result. This period can vary from a few years to even lifelong retention all depending upon the clinician, type of treatment and severity of the initial malocclusion. In most cases retention is planned for one to two years, but some clinicians routinely recommend continuous retention into adulthood. The retention planned for a patient is unfortunately often based on intuition rather than on scientific evidence. Furthermore, the retention is frequently not planned based on the initial malocclusion, the patient's facial growth pattern nor is attention paid to …

Oral Leukoplakia: Diagnosis And Management Revisited, Isaäc Van Der Waal

Journal of Dentistry Indonesia

The definition of oral leukoplakia has not much changed during the past five decades and is still a definition by exclusion of ‘known’ lesions. Therefore, a diagnosis of leukoplakia is not always a straightforward one for the clinicians and, to some extent, also for the pathologists. The traditional clinical classification in homogeneous and nonhomogeneous leukoplakia may just be simplified into leukoplakia (thin and thick/verrucous) and erythroleukoplakia. In spite of numerous reported predictive molecular and genetic parameters of malignant transformation, the presence and grade of epithelial dysplasia as assessed by histopathological examination is still the most important one. Of the various …

Treatment Of Gingival Fenestration Using Mucoperiosteal Flap With Connective Tissue Graft: A Report Of Two Cases, Swati Jaglan, Shikha Tewari

Journal of Dentistry Indonesia

Fenestration term is derived from the Latin word ‘fenestra’ means ‘window’. Gingival fenestration is not found in routine while its actual occurrence is assumed to be higher. Additionally, if these mucogingival defects persist for a longer duration it may lead to adverse outcomes like compromised esthetics, hypersensitivity, plaque and calculus deposition, and susceptibility to dental caries. Present cases of gingival fenestration were successfully treated by using full-thickness flap elevation with connective tissue graft placement. Two cases were presented with the accumulation of plaque and calculus and having gingival fenestration to the respective sites. After phase 1 therapy, full thickness flap …
