this case report presents an uncommon case of maxillary molar with two palatal root canals and an enamel pearl in the furcation area. the article discusses root canal complexities of maxillary second molars as well as possibility of coexisting anomalies in the region that makes radiographic interpretation difficult and compromises the success of endodontic treatment.

IJMDS ● www.ijmds.org ● January 2015; 4(1) 560 Original Article Influence of first premolar extraction on second and third molar angulation A clinical study Tarvade SMT, Biday S ABSTRACT Background: In modern populations, the impaction rate is higher for third molars than for any other tooth. Due to the speculation of third molar role on late incisor crowding, many orthodontists prescribe remov...

BACKGROUND There are controversial opinions about the effect of erupted second molars on distalization of the first molars. Most of the distalizing devices are anchored on the first molars, without including second molars; so, differences between sequentially distalize maxillary molars (second molar followed by the first molar) or distalize second and first molars together are not clear. The ai...

OBJECTIVE Attempts to treat class II malocclusions without extraction in non-compliant patients have led to utilization of intraoral molar distalizing appliances. The purpose of this study was to investigate dental and skeletal effects of Bonded Molar Distalizer (BMD) which is a simple molar distalizing appliance. MATERIALS AND METHODS Sixteen patients (12 girls, four boys) with bilateral hal...

Nucleophilic cycloaddition of thiocyanates 1a-e with C60 in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene afforded C60-fused 2-iminotetrahydrothiophene derivatives 2a-e and methanofullerenes 3a-d. The product distributions were highly sensitive to the substrates employed. The 2-iminotetrahydrothiophene derivatives 2a-e could be further manipulated by hydrolysis and acetylation to give 2-ox...

We compare 4 statistical models for the establishment of assigned values in a control serum which are based on the assumption of a normal distribution. The first model results in mean +/- 2s, whereas each of the following 3 models are based on a special analysis of variance. We studied by means of appropriate statistical tests the distributional properties of the data of the study described in ...

A prevailing description of the stripe phase in underdoped cuprate superconductors is that the charge carriers (holes) phase segregate on a microscopic scale into hole-rich and hole-poor regions. We report resonant elastic x-ray scattering measurements of stripe-ordered La(1.475)Nd(0.4)Sr(0.125)CuO(4) at the Cu L and O K absorption edges that identify an additional feature of stripe order. Anal...

Absolute transition frequencies of the 2s 2S{1/2}→2p2P{1/2,3/2} transitions in Be^{+} were measured for the isotopes ^{7,9-12}Be. The fine structure splitting of the 2p state and its isotope dependence are extracted and compared to results of ab initio calculations using explicitly correlated basis functions, including relativistic and quantum electrodynamics effects at the order of mα(6) and m...
