A finite element model is used to explore the stress-strain responses of the mandibular central incisor and its associated periodontal ligament (PDL) while opening the bite. The finite element model consisted of the mandibular teeth, the alveolar bone, and the PDL of the mandibular incisors. The clinical scenario was simulated by applying a force of 10 cN to the mandibular incisor in a crown-ro...

Mandibular fractures in infants are rare. This case report describes management of a mandibular fracture in an 11-month-old infant using a microplate and screws with open reduction. The surgical treatment was successful. Because the bone fragments were displaced and only the primary incisors had erupted, conservative treatment, such as an acrylic splint and circummandibular wiring, was not reco...

Aims: The aim of the study was to show a case with midline diastema in patient high periodontal risks and gingival recessions treated clear aligners. objective predict quantify root movements using dedicated software that extrapolates data from Cone Beam Computed Tomography (CBCT). Case Presentation: A 31-year-old female mandibular asked for an aesthetic treatment. She had vertical bone loss on...

OBJECTIVE To reassess the inclination of lower incisors and evaluate possible associations with gender, age, symphyseal parameters, and skeletal pattern. MATERIALS AND METHODS Twelve hundred and seventy-two (605 females, 667 males) cephalograms of untreated subjects of a craniofacial growth study (age: 8-16 years) were evaluated. Correlations between the angulation of the lower incisors and a...

Congenital missing of mandibular permanent incisors with retained primary incisors may jeopardize the esthetic appearance and psychological development of children, especially during the years of transition into adolescence. The retained primary teeth are necessary for the maintenance and normal development of alveolar bone, which in turn is essential for future definitive rehabilitation. In su...

Aim Stripping is a technique of creating space for correction of crowding by interproximal enamel reduction. This study sought to assess the efficacy of mesial stripping of mandibu-lar deciduous canines for correction of rotated and lingually erupted lateral incisors. Materials and methods This clinical trial was performed on 42 patients with <3 mm mandibular anterior crowding. The required s...

PURPOSE The purpose of this study was to evaluate the color of primary teeth. METHODS A Vita Easyshade intraoral spectrophotometer was used to determine the color of primary teeth: (1) maxillary central incisors, canines, and first molars; and (2) mandibular central incisors, canines, and first molars. A total of 604 teeth were measured. Color difference was compared to DeltaE*=2.7 (mean=50:5...

Dentigerous cyst is a benign odontogenic cyst associated with the crowns of permanent teeth. It is usually single in occurrence and located in the mandible of middle-aged persons. The teeth commonly affected are in order of frequency, the mandibular third molars, maxillary canines, maxillary third molars and, rarely central incisors. The present case report describes the surgical enucleation of...
