This reflection describes a life-limiting case of oral squamous cell carcinoma (SCC) that required thoughtful management facilitated by an advance care plan (ACP). A 70-year-old female was diagnosed with a T4aN2bM0 biopsy-proven invasive, well-differentiated keratinizing SCC. Surgical wide-local excision included teeth #11-16 with left unilateral neck dissection, levels I-V. She was rehabilitated with maxillary obturator prosthesis and underwent chemoradiation therapy. Her course was complicated by dysphagia and trismus...

The patient with a Class II malocclusion, proclination, or moderate crowding of the mandibular anterior teeth, and a moderate-to-low mandibular plane angle is a treatment-planning challenge. The records of 3 patients are presented. For 2 of them, extraction treatment was used to resolve the Class II malocclusion problem. Each of these patients was treated with the removal of maxillary first premolars and mandibular second premolars. The third patient was treated with Class II elastics without extractions. The clinician must weigh the pros and cons of each approach and decide which approach will give the patient the best long-term benefit...

Objective: To investigate and compare the sensitivities of early childhood caries detection by using international caries detection and assessment system (ICDAS)-Ⅱ and WHO criteria. Methods: A total of 449 3-year-old children from four day care kindergartens in Beijing were enrolled in this study. Both ICDAS-Ⅱ and WHO criteria were used to assess the prevalence of caries in the given subjects. The decayed, missing, and filled teeth (dmft) index scores were calculated. In ICDAS-Ⅱ system, four cut-off points (D1, D2, D3 and D4) were employed to differentiate sound and decayed teeth: D1 (score 0 as sound, scores 1-6 as caries); D2 (0-1 sound, 2-6 caries); D3 (0-2 sound, 3-6 caries) and D4 (0-3 sound, 4-6 caries)...

This clinical report describes an 8-year follow-up evaluation using different thicknesses of porcelain laminate veneers of diastema and malformed anterior teeth. Minimally invasive treatment with no preparation or minimal reduction options could be considered and chosen based on the characteristics of each case. Laminate veneers with or without reduction can offer an excellent result regarding esthetics and function. Despite its failure without reduction, this treatment is indicated because it can be applied regardless of the structure of the teeth...

From World War II to the end of 20th century, the types of patients undergoing orthodontic treatment and their reasons for doing so changed significantly. In the 1950s and 1960s, Canadian parents were told that orthodontics would "cure" inferiority complexes and protect children with crooked teeth, especially girls, from a life of delinquency and missed opportunities. By the last two decades of the 20th century, the consumer health movement and rising incomes empowered patients to decide which treatments were right for them, and an increasing number of adult patients sought orthodontic treatment to improve their appearance...

Odontogenic myxoma is an aggressive benign odontogenic tumor, accounting for 3-6% of all the odontogenic tumors in adults. The incidence among children is lower. Due to its clinical behavior, there is no consensus on the best treatment. In this paper, the authors report the case of a 9-year-old girl with the diagnosis of odontogenic myxoma. The panoramic X-ray showed an extensive radiolucent lesion involving the left mandibular body causing teeth displacement. The treatment consisted of tumor enucleation followed by vigorous curettage of the bone walls...

Hereditary sensory and autonomic neuropathy type IV (HSAN IV), or congenital insensitivity to pain with anhidrosis, is an exceptionally rare genetic disorder that results in the complete loss of pain and temperature sensation as well as anhidrosis. Anesthetic management of these patients can be difficult because of significantly increased risks during general anesthesia. Literature on perioperative anesthetic management is typically written in the context of a hospital setting. As such, our case presents a unique report on the anesthetic management of a HSAN IV patient who presented for extraction of 2 teeth in an office-based setting...

Background: Iron supplement is recommended for alleviating iron deficiency. Black discoloration of teeth is one of the side effects of consumption of iron supplements. Besides these effects, iron drops may also act directly on the dental hard tissues, with erosive lesions as possible outcomes of their content. In this regard, we decided to compare iron absorption of five types of iron drops in enamel and determine its relationship with pH and titrable acidity (TA) of them. Materials and Methods: In this in-vitro study The pH of 5 kinds of iron was measured by a digital pH meter...

The teeth become very close to each other when they are crowded, but their structures remain individualized and, in this situation, the role of the epithelial rests of Malassez is fundamental to release the EGF. The concept of tensegrity is fundamental to understand the responses of tissues submitted to forces in body movements, including teeth and their stability in this process. The factors of tooth position stability in the arch - or dental tensegrity - should be considered when one plans and perform an orthodontic treatment...

Mandibular implant placement (MIP) has been accepted and widely used for decades all over the world, and has reached a very high level of therapeutic reliability. MIP is used mostly in elderly edentulous patients who lost their teeth when dentistry was not oriented to fixed or removable prosthetic. Notwithstanding this, every year cases of severe complications during MIP due to haemorrhage causing life-threatening airway's obstruction are reported. These severe complications of MIP need immediate therapy, usually with hospitalization, and may be potentially fatal...

BACKGROUND: Methemoglobinemia is a well-recognized adverse drug reaction related to the use of certain local anesthetic agents. The mainstay of treatment for methemoglobinemia is i.v. methylene blue, along with provision of supplemental oxygen; however, methylene blue is listed as a category X teratogen. This poses an issue should methemoglobinemia develop during pregnancy. CASE REPORT: A 35-year-old, 20-week and 5-day gravid female was transferred from an outpatient oral surgeon's office for hypoxia...

OBJECTIVES:   Composites can be classified differently, according to manufacturer information, filler particle size, resin-monomer base, or viscosity, for example. Using clinical trial data, network meta-analyses aim to rank different composite material classes. Dentists then use these ranks to decide whether to use specific materials. Alternatively, annual failure rates (AFRs) of materials can be assessed, not requiring any classification for synthesis. It is unclear whether different classification systems lead to different rankings of the same material (ie, erroneous conclusions)...

This report presents two cases of tooth autotransplantation using cone-beam computed tomography (CBCT), the three-dimensional (3D) simulation dental planning software and a computer-aided rapid prototyping (CARP) model. Two hopeless teeth of adult patients were replaced as their third molar teeth. Before deciding the autotransplantation, diagnostic CBCT images were acquired and imported to SimPlant software. The SimPlant dental program was used for surgical simulation prior to autotransplantation, which created 3D images of the available donor teeth and recipient site tooth and superimposed the images to display their morphological similarity...
