Diagnosis and Management of Oral Lesions and Conditions: A Resource Handbook for the Clinician
This handbook has the goal of providing a short and objective approach to the diagnosis and management of common oral lesions and conditions likely to be encountered in the daily practice of dentistry by the general practitioner. Each of the lesions/conditions will be grouped based on their nature, inflammatory or infectious, benign or malignant, variants of normal, bony lesions, etc. The individual lesion/condition will be described based on common clinical signs and symptoms, differential diagnosis, best approach for diagnostic confirmation, and brief management strategy. One of the chapters is dedicated to oral hygiene and oral health maintenance recommendations.

Teeth and their surrounding structures are exceptional sources for addressing significant questions in numerous disciplines. In this publication, an international, multidisciplinary team of researchers addresses important issues on current aspects of dental morphology research from evolutionary, anatomical, clinical and archaeological perspectives. In combining leading-edge methods of data acquisition and analyses, such as molecular analyses and highly advanced non-destructive imaging technologies, the book demonstrates how information about various aspects of dental morphology can be used to explore the evolution of vertebrate life histories, a subject most relevant to our own species. The chapters provide profound discussions on dental evolution, dental morphology, dental tissues, dental growth and development, as well as on clinical aspects of dental morphology. As a special feature, the publication provides new information about the role of teeth as tools in reconstructing the nature and behaviour of past populations.
This book will serve as an important reference for researchers of dental sciences, anatomy, evolutionary biology, paleoanthropology, paleontology, archaeology, prehistoric anthropology, comparative anatomy, genetics, embryology, and forensic medicine.
Permar's Oral Embryology and Microscopic Anatomy
Permar's Oral Embryology and Microscopic Anatomy continues to provide comprehensive, yet concise coverage of embryology and histology for dental hygiene and dental assisting professions. It can also be used as an introductory text for dental students. This text begins with the basics of general histology, progresses through the development of the human embryo and fetus, and concludes with a focus on the development of the face and oral cavity. New to this edition are over 40 additional illustrations, including four-color micrographs. High-quality images of microscopic embryonic development and oral anatomy help students identify histologic structures. A new chapter regarding salivary glands includes information about remineralization, demineralization, fluoride, bacterial diseases, and HIV. Clinical aspects of oral tissue are covered to help readers expand their knowledge from basic to clinical sciences and apply fundamental principles. Suggested readings help readers find additional resources.
A biometric approach to predictable treatment of clinical crown discrepancies
Dental professionals have long been guided by mathematical principles when interpreting aesthetic andtooth proportions for their patients. While many acknowledge that such principles are merely launch points for a smile design or reconstructive procedure, their very existence appears to indicate practitioners’ desire for some predictable, objective, and reproducible means of achieving success in aesthetic dentistry.
The clinical reality, however, is that intra-arch tooth relationships used as guidelines for smile designs (eg, the Golden Proportion) are applicable to a confined segment of the patient population.1 In addition, dentists have been found to be less pleased with aesthetic outcomes with smiles designed using the Golden Proportion,2 and patients have been found to dislike such a proportion relationship. 3 Therefore the only tangible parameter in aesthetic dentistry is individual tooth size and proportion.4,5 Individual tooth size can be thought of as the building blocks of a smile design. Once the tooth size and proportion of the maxillary anterior teeth are corrected, they can then be arranged within the dental arch. Intra-arch tooth relationship proportions such as the recurring aesthetic dental proportion,6 which has been found to be amenable to patients and clinicians, can be used to arrange the teeth

for a pleasing smile.6 This task is simplified in removable prosthodontics, in which selection of the proper tooth size and form is the primary step before their arrangement within
the dental arch or tooth setup. With the natural dentition, this task is infinitely more difficult, since the dilemma is such that existing teeth may exhibit altered width and/or length discrepancies due to developmental anomalies, changes resulting from the aging process, or prior restorative
procedures. Therefore, correction may require combination therapies such as orthodontics and/or periodontics prior to aesthetic restorative dentistry

In daily practice, the clinician’s use of “nonstandard” proportions to treat teeth with abnormal size relative to accepted width and height values can yield narrow or square teeth that are unnatural in size and shape and fail to achieve the aesthetic expectations of either the patient or clinician. This can be particularly challenging when performed with visual assessment only (ie, absent of clinical tools). Standardized individual tooth size and proportions fall within a given range around mean values, however, and gender differences exist between anterior tooth groups.7 Therefore, these parameters can be used to predictably diagnosis and correct discrepancies in tooth size

Historical Background
Traditionally, dental instruments (eg, explorers, probes) have been used as reference standards to detect diseases such as caries and periodontitis. Periodontitis is detected, evaluated, and assessed using numerical values indicative of health or stage of disease.8-11 Instrumentation does not exist, however, to address aesthetic deformities from diagnosis to correction
Traditionally, dental instruments (eg, explorers, probes) have been used as reference standards to detect diseases such as caries and periodontitis. Periodontitis is detected, evaluated, and assessed using numerical values indicative of health or stage of disease.8-11 Instrumentation does not exist, however, to address aesthetic deformities from diagnosis to correction
Aesthetic tooth dimensions can be evaluated and treated by similar numerical analysis. To test the application of these concepts, the author created prototype instruments. Metal wire (ie, 0.036 gauge) was soldered to form a Siamese twin instrument tip with preset markings notched into the surface with measurements indicating a 78% width (W) to length (L), proportion
(Figure 1). Once the incisal edge position was established, the width of a tooth could be measured with the prototype instrument, and the notch on the short arm noted; then the corresponding notch on the long arm could be marked as the reference point for the new clinical crown length at a preset W/L ratio (Figures 2 through 4
(Figure 1). Once the incisal edge position was established, the width of a tooth could be measured with the prototype instrument, and the notch on the short arm noted; then the corresponding notch on the long arm could be marked as the reference point for the new clinical crown length at a preset W/L ratio (Figures 2 through 4
Revolutionary Instrumentation
Aesthetic measurement gauges (ie, Chu’s Aesthetic Gauges, Hu-Friedy Inc, Chicago, IL), designed for diagnosis and correction of tooth size discrepancies and deformities, have been developed to eliminate the subjectivity associated with restorative care

These measurement tips include the Proportion Gauge (PG), which represents an objective mathematical appraisal of tooth size ranges. Through the use of such instrumentation, the clinician has a clearly visible means of applying aesthetic values to a patient chairside, directly or indirectly in the laboratory during projected treatment planning, and to objectively determine the intended treatment outcome
The PG is designed as a double-ended instrument (ie, gauge) with a T-Bar and In-Line tip screwed into the handle at opposing ends. The T-Bar tip features an incisal edge position (ie, incisal stop); when a tooth is oriented with the tip accordingly, the practitioner can accurately evaluate its length (ie, vertical arm) and width (ie, horizontal arm) dimensions simultaneously. The width is indicated in equidistant 0.5-mm increments bilaterally, each with a vertical mark in a corresponding color (Figure 5).Thus, a central incisor with a “red” width of 8.5 mm will be in proper proportion if its height is also the “red” height (ie, 11 mm
The In-Line tip is analogous to the metal prototype used in the aforementioned case study; the most significant difference being that the latter is a color-coded,
plastic, disposable unit. The utility of the In-line gauge is identical to the T-Bar tip, except for the fact that the horizontal arm of the T-Bar is now the short arm of the In-Line tip; the vertical arm and long arm of the tips are also the same. The short arm, at 1-mm increments, measures
the tooth width, and the long arm measures the corresponding length at alternating 1.5-mm/1-mm increments, since the gauge is mathematically set at 78% W/L proportion. The black line at the base of the tip denotes the incisal guide, which is the starting point of measurement (Figure 6

This can cause binding and notching of the wire at the locations of the most misaligned teeth, resulting in increased friction and thus negating the archwire’s superelastic
properties.2,3 Potentially harmful forces are also placed on the anchorage unit when aligning ectopic teeth.4 Furthermore, bonding brackets to the buccal

and retroclined maxillary right lateral incisor in crossbite before treatment.
Although she had experienced a trauma to the maxillary left central incisor, there was no contraindication to orthodontic therapy. Intraoral examination revealed mild maxillary skeletal constriction,
crowding in the maxillary arch, and partial closure of the maxillary left lateral incisor eruption space due to the migration of adjacent teeth. A Class I molar relationship was present (Table 1),
crowding in the maxillary arch, and partial closure of the maxillary left lateral incisor eruption space due to the migration of adjacent teeth. A Class I molar relationship was present (Table 1),
but the mandibular dental midline was deviated to the left. The maxillary right canine was erupting ectopically, and the right lateral incisor was in crossbite and severely retroclined relative to the other upper incisors.
Two treatment options were considered. The first involved extraction of the maxillary premolars to resolve the crowding and allow the canines to erupt without flaring of the incisors.
The second option was to expand both arches by means of fixed appliances, with no extractions.

The second option was to expand both arches by means of fixed appliances, with no extractions.
To maintain the patient’s profile, and because the maxillary expansion was expected to produce sufficient space for alignment, the second option was chosen.
Treatment Progress
Leveling and alignment were begun in the mandibular arch with full fixed appliances (Fig. 2).
Fig. 2 Self-ligating brackets bonded in lower arch for initial leveling and alignment.
Eight weeks later, the upper right canine had erupted enough to bond the maxillary teeth. We used self-ligating Bidimensional brackets6 (Time 2*) except on the retroclined lateral
incisor, where we bonded a stainless steel cleat to the lingual surface (Fig. 3).

An extremely thin, flexible archwire (.012" nickel titanium) was inserted through the bracket slots and bent around the cleat to progressively align the teeth.
This method has several advantages. The forces used are extremely light, but effective because friction is controlled. Binding is prevented by limiting the wire to one-point contacts with the brackets and by increasin
