BACKGROUND The present paper describes the oral manifestations in a 16-year-old boy previously diagnosed with Apert syndrome. PATIENT AND METHODS The extraoral and intraoral pathological findings were recorded. The following intraoral parameters were recorded: plaque and calculus deposits, dental caries, periodontal status, malpositions, and occlusion. For the upper anterior teeth, dental sha...
AIM To present a case report in which the pulp of two bilateral mandibular premolars with dens evaginatus were revascularized using a modified novel technique to avoid undesired crown discolouration. SUMMARY Recently, regeneration of necrotic pulps has become an alternative conservative treatment option for young permanent teeth with immature roots and is a subject of great interest in the fi...
BACKGROUND Conventional dentoalveolar osseous reconstruction often involves the use of grafting materials with or without barrier membranes. The purpose of this study was to evaluate the efficacy of bone induction for the placement of dental implants by two concentrations of recombinant human bone morphogenetic protein-2 (rhBMP-2) delivered on a bioabsorbable collagen sponge (ACS) compared to p...
The size of teeth is one of the crucial factors affecting occlusion formation. In the occurrence of the crowding of dental strings, the size of teeth has a significant role. The aim of the study was to determine the influence of the size of permanent frontal teeth (bicuspids) on the appearance of the crowding of the frontal segment of dental strings. The study included 140 subjects, aged 15-20 ...
Abstract Background Silver diamine fluoride (SDF) is a minimally-invasive preventive service used in the U.S. to avert and arrest caries since 2014. No studies document survival outcomes based real world delivery. We analyzed 12-month of SDF applied independently or concurrently with other restorative procedures among population receiving community dental care. Methods data on applications from...
The reproducibility of measurements of alveolar bone loss on radiographs may be a problem on epidemiologic studies, as they are based on comparisons of the diagnosis of various examiners. The aim of the present research paper was to assess the inter- and intra-examiner reproducibility of measurements of the interproximal alveolar bone loss on non-manipulated digital radiographs and after the ap...
OBJECTIVE The aim of this study was to evaluate, ex vivo, the precision of five electronic root canal length measurement devices (ERCLMDs) with different operating systems: the Root ZX, Mini Apex Locator, Propex II, iPex, and RomiApex A-15, and the possible influence of the positioning of the instrument tips short of the apical foramen. MATERIAL AND METHODS Forty-two mandibular bicuspids had ...
Forensic Odontology is a branch of Dentistry that works with the Law in assisting Justice and the professional involved in this specialty helping the identification of human remains, in various situations – charred corpses, cadavers and unidentified bodies. The aim of this paper was to list and analyze the number and types of teeth present in cadavers submitted to the Forensic Anthropology Lab ...
Background: The purpose of this study was to assess the antimicrobial effect of a buffered 0.5 % sodium hypochlorite solution activated by photon-induced photoacoustic streaming compared to conventional irrigation. Methods: The canals on 48 single canal lower bicuspids were cleaned and shaped using rotary instrumentation. All roots were autoclaved for 20 min. Thirty-six of the roots were placed...
objective : the aim of this study was to evaluate fracture characteristics of rigid two-tooth segments splinted with fiber reinforced composite (frc), with and without application of simulated masticatory forces. material and methods: in this experimental study, 80 extracted maxillary bicuspids were joined in pairs from the buccal aspect using frc. the specimens were divided into two groups. in...
