Human mandibular canines do not present an internal anatomy as simple as could be expected; there are such canines with a single root and two canals, two roots or fused roots. The existence of mandibular canines with more than one root canal is a fact that clinicians ought to keep in mind, in order to avoid failure during endodontic treatment. In spite of the low incidence of lower canines with...

Six young adults were found to have transmigrated mandibular canines. One patient presented with two transmigrated canines. Of the seven impacted teeth, the left mandibular canines was involved in five instances and the right two. In all patients, the primary canine was present in the dental arch. A supernumerary tooth was disclosed on the panoramic radiograph of two patients. Five patients und...

OBJECTIVE There is little information regarding the mesiodistal angulation of permanent teeth in mixed dentition. The aim of this study was to evaluate mesiodistal root angulation of permanent incisors, canines and first molars of 100 Brazilian children, using a new horizontal reference plane based on the midpoint of the intercuspation of primary canines and permanent first molars in panoramic ...

Impacted and transposed teeth cause serious difficulties in tooth eruption and movement as well as esthetic and functional outcomes. Proper treatment planning including good biomechanical control is essential in order to avoid side effects during traction and aligning of the impacted and/or transposed teeth. The purpose of the present study was to present a successfully treated female patient h...

M axillary canines and incisors often lack an adequate cingulum to allow for a conventional cingulum rest preparation (Fig. 1). Cingulum rests on mandibular canines have often not been used because of the perception that there is not adequate thickness of enamel in the rest region. This has recently been refuted in research by Rossi,’ who found that if the rest seats are prepared on mandibular ...

The mandibular canine is usually considered a single-rooted tooth with a single root canal. However, two canals and more rarely two roots may also occur. This paper reports the case of a patient with bilateral mandibular canines with two roots and two root canals. The initial periapical radiographs of the mandibular right and left canines for endodontic treatment revealed the presence of two ro...

BACKGROUND Mixed dentition space analysis forms an important part of orthodontic diagnosis and treatment planning. Regression equations are widely used for mixed dentition analysis which can vary among races. This study aimed to find out the new regression equation in estimating the size of unerupted canines and premolars for Nepalese Brahmins/Chhetris. METHODS Hundred Nepalese Brahmins/Chhet...

PURPOSE The aim of this study was to determine the absolute value of the root/crown ratio (R/C ratio) using panoramic radiographs (PRGs) in a healthy Korean population. MATERIALS AND METHODS In total, 99 patient radiographs (of 50 males and 49 females subjects; aged 16 to 24 years old) were examined, and 2,770 teeth were analyzed. Crown lengths and root lengths were measured with modified Lin...

The anatomy of mandibular canines is not always as simple as can be expected. Their existence of mandibular canines with two root and even more than one root canal must be taken into account in order to prevent the failure of endodontictreatment. The precise knowledge of these anatomical variations is essential for proper root canal therapy and consequently for the long term success, because th...

Mandibular canines exhibit the greatest sexual dimorphism amongst all teeth. The present study was performed on 368 healthy MBBS students of Medical College, Bhavnagar (216 males, 152 females) of 18 – 24 years with the aim to investigate whether any correlation existed between odontometric measures including mandibular canine index, and sex determination in the year of 2006. Mean value of inter...
