Objectives. The aim of this study was to investigate the number of roots and root canals in the maxillary second premolar in a group of Jordanian population. Materials and Methods. A total of 217 patients, 100 female (46%) and 117 male (54%), received root canal treatment of maxillary second premolar from January 2012 to January 2014. The mean age of the patients was 32.7, ranging from 18 to 60...

PURPOSE This report involves the retrospective analysis of ITI implants placed and/or restored by a group of 7 clinicians located throughout the United States (5 periodontists and 2 prosthodontists). MATERIALS AND METHODS Six hundred seventy-five posterior single-tooth implants were restored in 471 patients (average time of loading 21.30 months, with a range of 1 to 78 months). Three hundred ...

The objective of this study was to determine the relative prevalence of caries in first and second premolars as well as maxillo-mandibulo-quadrant distribution of caries among the premolars. It was also aimed at comparing the patterns of caries distribution in first and second premolars with those of the first and second permanent molars based on previous studies. The treatment records of patie...

In clinical settings, impacted teeth are a typical occurrence. Because of their proximity to the nasal and oral cavity, have potential create more severe catastrophic difficulties, such as formation dentigerous cysts other disorders. The goal this report is look into fundamentals treating maxillary premolars that been palatally impacted. A case right second premolar presented in report.

Patient Jiang, Female,25 years old, came to the clinic for irregular teeth. The case was reported as lingual tipping deep overbite with maxillary undersized lateral incisors, which patient did not accept restore malocclusion morphology by denture, resulting in selection of extraction bilateral incisors and mandibular second premolars, orthodontic treatment zirconia straight wire appliances comb...

The intrusion of an overerupted maxillary molar using traditional orthodontic treatment is a real challenge. The aim of this study was to investigate the envelope of intrusive movements of a maxillary molar in cases using mini-implants as anchorage with partial or full-mouth fixed edgewise appliances. The cusp tips of the pretreatment and postintrusion dental casts were recorded by a three-dime...

This article describes a method to treat Class II malocclusions with no patient cooperation. The technique involves converting the Class II molar relationship to a Class I in the initial phase of treatment by moving the maxillary molars distally with superelastic coils and wire. Anchorage is provided by a transpalatal bar attached to the first premolars and connected to 2 palatal miniscrews. On...

A 17-year-old female presented with the chief complaint of inability to bite properly. Clinical examination revealed a Class II, division 1 malocclusion with an anterior open bite and mild maxillary and mandibular tooth-sizearch-length discrepancies (Fig. 1, Table 1). The patient’s initial contact upon closure was between the maxillary and mandibular first molars, leading to a complex open bite...

Dental enamel thickness continues to feature prominently in anthropological studies of ape and human evolution, as well as studies of preventative oral care and treatment. Traditional studies of enamel thickness require physical sectioning of teeth for linear and scaled measurements. Recent applications of microtomographic imaging allow scientists to employ larger and more diverse samples, incl...
