The purpose of this study is to compare the anterior tooth size width in patients with congenitally missing maxillary lateral incisors using the Bolton Index and divine proportion. The study sample consisted of thirty pairs of orthodontic models with unilateral (twelve patients; 7 females, 5 males) and bilateral (eighteen patients; 13 females, 5 males) absence of maxillary lateral incisors. The...

BACKGROUND The prevalence of impacted maxillary canine is reported to be between 1% and 3%. The lack of monitoring and the delay in the treatment of the impacted canine can cause different complications such as: displacement of adjacent teeth, loss of vitality of neighbouring teeth, shortening of the dental arch, follicular cysts, canine ankylosis, recurrent infections, recurrent pain, internal...

Force generated by the perioral musculature is known to be a potent factor that can affect tooth position and malocclusion. To evaluate the influence of the force of the orbicularis oris muscle on incisor position, we determined the maximum and average strengths of the upper lip of male Class I malocclusion patients with a Y-meter, which was devised to measure the vertical closing force of the ...

DR. MARQUARDT It does seem to occur throughout nature in many biologic systems, including flowers and the leaf divergence from a stem in plants, and particularly in humans. For example, the width of the nose to the width of the mouth is a ratio of 1:1.618 in a beautiful face. In an ideal dentition, the width of the maxillary central incisor is 1.618 times the width of the maxillary lateral inci...

This paper describes an operated oblique facial cleft case with external inflammatory root resorption (EIRR) of the permanent maxillary left incisors and canine in a 12-year old patient. Due to the facial oblique cleft, the plastic surgery department operated on the patient five times and placed her on fixed orthodontic therapy. EIRR treatment of the maxillary left incisors and canine was perfo...

The purpose of this study was to determine the upper lip by Holdaway’s method in individuals with bimaxillary proclination and to find out correlations of skeletal convexity at point A & maxillary incisor inclination with upper lip inclination and upper lip strain. Lateral cephalograms of 100 patients (50 males and 50 females) exhibiting bimaxillary dental proclination were exposed in closed li...

The term talon cusp refers to a relatively rare dental anomaly in which an accessory cusplike structure projects from the cingulum area or cement-enamel junction. The condition can occur in either maxillary or mandibular anterior teeth in both the primary and permanent dentitions. This article reports 2 cases of talon cusp affecting consanguineous first cousins: a case of bilateral talon cusps ...

A radicular cyst arises from epithelial remnants stimulated to proliferate by an inflammatory process originating from pulpal necrosis of a non-vital tooth. Radiographically, the classical description of the lesion is a round or oval, wellcircumscribed radiolucent image involving the apex of the tooth. A radicular cyst is usually sterile unless it is secondarily infected. This paper presents a ...
