Success of endodontic treatment depends on the proper identi-fication of all the canals, thorough chemomechanical preparation followed by three-dimensional obturation with hermetic seal. Failure of any of these steps may occur due to unusual tooth morphology. Usually mandibular molars have two roots with three canals but in few teeth, the number of roots and canals vary. The variation in the nu...

The Frequency with which impacted supernumerary teeth are encountered in a clinical setting is relatively high, with the majority of such cases occurrig in the median maxillary region, and very few in the molar region. In the molar region, mandibular distomolars (fourth molars) are very rare. Although a small number of case reports have described impacted supernumerary distomolars, very few hav...

Introdouction: Impacted and partially erupted third molars can cause various symptoms and pathologies. The aim of this study was to determine the association between commonly observed pathological conditions and the impaction depth of lower third molar teeth. Materials and methods: In this retrospective study, 370 panoramic radiographs including 724 lower third molars were evaluated to asses...

OBJECTIVE In this study, we measured the cortical bone thickness in the mandibular buccal and lingual areas using computed tomography in order to evaluate the suitability of these areas for application of temporary anchorage devices (TADs) and to suggest a clinical guide for TADs. METHODS The buccal and lingual cortical bone thickness was measured in 15 men and 15 women. Bone thickness was me...

Aims: The aim of this study is to determine the effectiveness of mandibular infiltration compared with the mandibular block in treating mandibular primary molars in children and to relate it to the type of treatment performed. Materials and Methods: The study design was case control study. The study sample consisted of 98 cooperative children of age 3-9 years old. Forty eight children were the ...

Knowledge about the external and internal anatomy of the tooth is essential for successful dental practice. Anomalies in the tooth are often encountered which poses difficulties in dental treatments. As like any other tooth, mandibular first molars are also prone for anatomic malformations. One such anatomic variation is the presence of extra root distolingually. This distolingual root is calle...

introduction: the purpose of this study was to evaluate the number of distal roots and canals in mandibular first molars and their internal anatomy radiographically within iranian population. materials and methods: a total of 310 distal roots of mandibular first molars were incorporated in this study and evaluated in terms of number of roots and number and types of canals. root canal systems we...

Purpose: The purpose of this research was to identify the most common and severe types pathologic diseases surrounding impacted mandibular third molars using radiographic imaging. Cases procedures: An analysis past patients who had extracted at Oral & Maxillofacial Surgery Cat D Hospital Gara Tajik Peshawar. Impacted molar lesions, patient age gender were used as study's outcome measures. C...

As PART of a study of spacing-crowding at the Burlington Orthodontic Research Centre, cognisance was taken of the presence of mesial and distal restorations in primary molars in the sample. Since at age nine, more than half the sample of primary molars which could be measured had such restorations, the validity of the spacingcrowding data could be questioned. Specifically, it was of interest to...
