‘Just keep on walking in a straight line': allowing for chance in Zadie Smith's overdetermined London (White Teeth, The Autograph Man and On Beauty)
2008
International audience; Zadie Smith's three novels signal a sullen yet coherent evolution in the representation of both real and fictional London. Each of the three texts reveals a threefold failure in the way the city can become the ideal place for the characters to know and fulfil themselves. London is first a mere topographical and cultural gridlock: its neighbourhoods are overdetermined in a way that leads to the negation of the individual, leaving no space for action and banning any type of self-improvement. Yet Smith's London in White Teeth is not as coded as often claimed, and may provide some tools to pervert this conditioning of places and people. The novels indeed examine the dyna…
The effects of three remineralizing agents on regression of white spot lesions in children: A two-week, single-blind, randomized clinical trial.
2016
Background This study investigated the effect of three remineralizing agents on improving white spot lesions (WSLs). Material and Methods This clinical trial included children who had at least one WSL on anterior teeth of upper or lower jaws. The participants were randomly assigned to 4 groups by treatment: 1) a cream containing casein phosphopeptide-amorphous calcium phosphate and fluoride (MI Paste Plus); 2) a cream containing hydroxyapatite and fluoride (Remin Pro); 3) a 2% sodium fluoride gel; and 4) usual home care (control). The treatment was performed for 3 times over 10 days using special trays for retaining remineralizing agents. The area and mineral content of WSLs were measured a…
Periodontal Behavior and Patient Satisfaction of Anterior Teeth Restored with Single Zirconia Crowns Using a Biologically Oriented Preparation Techni…
2021
bjectives. The aim of this study was to analyze the behavior of the periodontal tissues around teeth in the anterior region when restored with zirconia single crowns, using a biologically oriented preparation technique (BOPT), over a 6-year follow-up. Methods. The study investigated tooth-supported single crowns in the anterior region that were fabricated with a zirconia core and feldspathic ceramic covering, in 34 patients. Follow-up analysis took place annually for 6 years, assessing periodontal responses by evaluating the following variables: plaque index (PI)
Third molar surgical difficulty scales: systematic review and preoperative assessment form
2021
Background The main objective of this systematic review was to collect the pre-existing scales for assessing the difficulty of third molar extraction. The secondary objective was to design a proposal for a preoperative evaluation protocol for the difficulty of third molar extraction. Material and Methods Two independent researchers conducted an electronic search in Pubmed (MEDLINE), Cochrane, and Scopus databases during March 2021. Included studies evaluated the prediction of the difficulty of surgical removal of impacted upper or lower third molars using new indices/scales or pre-existing scales with or without modifications. Articles referring to coronectomies or assessing pre-surgical di…
A New System for Choosing the Form and Size of Complete Denture Anterior Teeth
2016
Introduction: In the absence of pre-extraction records, the choice of the size an form of anterior complete denture teeth can be extremely subjective. Several clinical and statistical parameters are usually used for choosing the correct size and form of the complete denture anterior teeth. Clinical Innovation: The technique consists of a system that allows the dentist to choose and, if necessary, easily change the dental mold during maxillomandibular recording session. The unique feature of the system is that six teeth of each mold are represented by veneers, which are connected to each other on the lingual surface by a fiber that allows each veneer some degree of movement. Discussion: This…
Morbidity of third molar extraction in patients between 12 and 18 years of age
2005
Objetivo: El propósito de este estudio fue analizar la incidencia de complicaciones después de la extracción quirúrgica de los terceros molares en pacientes de 12 a 18 años de edad. Pacientes y método: Se realizó un estudio retrospectivo de 390 extracciones quirúgicas de terceros molares superiores e inferiores en 173 pacientes en edades comprendidas entre los 12 y 18 años de edad, intervenidos bajo anestesia locorregional en el año 2000 en el Máster de Cirugía Bucal e Implantología Bucofacial de la Universidad de Barcelona. Los pacientes fueron divididos en tres grupos (A: 12-14 años, B:15-16 años, C: 17-18 años). Se registró la edad y el sexo del paciente, el motivo de la extracción, el g…

One reason for the mammalian clade’s success is the evolutionary diversity of their teeth. In herbivores, this is represented by high‐crowned teeth evolved to compensate for wear caused by dietary abrasives like phytoliths and grit. Exactly how dietary abrasives wear teeth is still not understood completely. We fed four different pelleted diets of increasing abrasiveness (L: Lucerne; G: grass; GR: grass and rice husks; GRS: grass, rice husks, and sand) to four groups of a total of 28 adult goats, all with completely erupted third molars, over a six‐month period. Tooth morphology was captured by medical computed tomography scans at the beginning and end of the controlled feeding experi…
Sāls nikotīna bāzes tvaicēšanas ietekme uz zobu krāsas maiņu
2022
Sāls nikotīna bāzes elektronisko cigarešu lietošana nesen ir kļuvusi populāra un pakāpeniski aizstāj tradicionālo smēķēšanu . Šī pētījuma mērķis bija noskaidrot nikotīna sāls elektronisko cigarešu lietošanas ietekmi uz zobu emaljas krāsas maiņu. Tika secinā ts, ka pašizveidotai fotometriskai sistēmai ir piemīt augsta precizitāte. Anketas dati norādīja, ka smēķētāji biežāk tīra zobus un lieto sojas mērci, taču retāk dzer tēju salīdzinot ar nesmēķētājiem. Smēķētāju iecienītākā garša bija augļu šķidrumi ar 20 mg /ml nikotīna. Smēķēšana kombinācijā ar tējas dzeršanu izmainīja zobu krāsu toņa zilidzelteno līdzsvaru (CIELab b* telpiskā koordināte) uz dzelteno pusi. Viena mēneša ilga smēķēšana spē…
Comparative Analysis of Root Canal Dentin Removal Capacity of Two NiTi Endodontic Reciprocating Systems for the Root Canal Treatment of Primary Molar…
2022
The objective of the present study was to evaluate and compare the dentin removal capacity of Endogal Kids and Reciproc Blue NiTi alloy endodontic reciprocating systems for root canal treatments in primary second molar teeth via a micro-computed tomography (micro-CT) scan. Materials and Methods: Sixty root canal systems in fifteen primary second molar teeth were chosen and classified into one of the following study groups: A: EK3 Endogal Kids (n = 30) (EDG) and B. R25 Reciproc Blue (n = 30) (RB). Preoperative and postoperative micro-CT scans were uploaded into image processing software to analyze the changes in the volume of root canal dentin using a mathematical algorithm that enabled prog…
