INTRODUCTION Transposition is an anomaly of tooth position, the most frequent of which involves the canine and the first maxillary premolar. We describe the orthodontic treatment of a unilateral transposition of an upper canine and an upper right first premolar in the permanent dentition. CASE PRESENTATION A 12-year-old Caucasian boy presented with transposition of his upper right canine and ...

OBJECTIVE To compare dentoalveolar and skeletal changes produced by the pendulum appliance (PA) and the distal screw appliance (DS) in Class II patients. METHODS Forty-three patients (19 men, 24 women) with Class II malocclusion were retrospectively selected for the study. Twenty-four patients (mean age, 12.2 ± 1.5 years) were treated with the PA, and 19 patients (mean age, 11.3 ± 1.9 years) ...

CASE REPORT A 37–years old male patient of Indian origin was referred to the Department of Conservative Dentistry and Endodontics for treatment of carious teeth. An intraoral examination revealed an Angle’s Class I molar relation with a well aligned upper and a lower arch. Full complement of permanent teeth was present. Generalized dental fluorosis was seen in teeth of both arches. Though the t...

The aim of this study was to assess the displacement of posterior teeth in maxillary complete dentures stored in water at 37 degrees C. Twenty acrylic resin-based maxillary complete dentures were constructed with the anterior teeth arranged in normal overlap and the posterior teeth in Angle class I. Metallic pins were placed on the labial cusp of the first premolars (PM), and on the mesiolabial...

OBJECTIVES: To determine the number and configuration of canals in permanent maxillary premolars using Cone Beam Computed Tomography (CBCT) relationship between count patient gender northwest region Pakistan. METHODS: This cross-sectional observational study was conducted at Khyber College Dentistry (KCD) Peshawar, Data collected from July 1st to 30th December 2020, 133 patient’s CBCT scans wit...

AIM To determine the association of impacted maxillary canines with other developmental dental anomalies and compare them with a control population and to compare palatally and labially impacted canine associated anomalies. METHODS AND MATERIALS Ninety non-syndromic orthodontic patients from a south Indian population, with either labial or palatal impactions of one or both maxillary canine te...

Two series of spiro[ [1]benzothiophene-3,2'-[1,3]thiazolidine]-2,4'-diones 5a-e and 6a-e were synthesized, characterized and evaluated for anticonvulsant activity. Reaction of [1]benzothiophene-2,3-dione (3) with certain arylamines afforded the corresponding Schiff bases 4a-e. Cyclization of 4a-e with thioglycolic or thiolactic acids brought about the target spiro compounds 5a-e and 6a-e respec...

The aims of the study were to analyse the records of 26 subjects (18 females, eight males) with maxillary canine-first premolar transposition (Mx.C.P1) together with 160 subjects with a palatally displaced canine (PDC) to determine the pattern of tooth agenesis in these cases and to compare them with similar samples reported in the literature. A strong association between Mx.C.P1, lateral incis...

Irradiation of 1-substituted benzotriazole arylhydrazones 3a-c, 4a,b and 5a,b with a 16 W low pressure mercury arc-lamp (254 nm) for 24 h gave phenanthridin-6-yl-2-phenyldiazines 9a-c, phenanthridin-6(5H)-ones 10a-c, 1-anilinobenzimidazoles 11a-c, 2-aryl-1H-benzimidazoles 12a-c, 1-arylamino-1H-benzimidazol-2-carboxylic acid ethyl esters 14a,b, 1-aryl-1H, 9H-benzo [4,5][1,2,3] triazolo[1,2-a]te...

A series of persulfated molecular umbrellas have been synthesized from putrescine, spermidine, spermine, lysine, and cholic acid (1a, 2a, 3a, 4a, and 5a) and their anti-HIV and anti-HSV activities determined. Despite it size, the most active of these conjugates (5a) was able to cross phospholipid bilayers made from 1-palmitoyl-2-oleyol-sn-glycero-3-phosphocholine (POPC) and 1-palmitoyl-2-oleoyl...
