The interactions of regular DNA and abasic site-containing DNA (AP-DNA) with quinolizinium (1a), the linearly fused benzo[b]quinolizinium (2a), the angularly fused benzo[a]quinolizinium (3a), benzo[c]quinolizinium (4a), and dibenzo[a,f]quinolizinium (5a) as well as derivatives thereof were studied with photometric and viscosimetric titrations (regular DNA), fluorimetric titrations and thermal D...

Introdouction: Cone-beam computed tomography (CBCT) scanning is a technological innovation developed in recent years with potential use in oral surgery and many other dental procedures. The aim of this study is to determine the maxillary sinus mucosal thickening in the maxillary premolar-molar area using the CBCT technique. Materials and methods: In this retrospective study, a total of 105 c...

This report describes a novel concept of relocating orthodontic mini-implants during dental distalization to provide unrestricted distal movement of the full maxillary dentition. The patient was an 18-year old Korean woman with a full-step Class II Division 1 malocclusion and mandibular deficiency. Mini-implants were initially placed bilaterally between the maxillary second premolar and the fir...

The purpose of the current study was to investigate if a significant relationship exists between ethnicity, sex, and short dental roots. The hypotheses are: 1. Hispanics have a higher prevalence of short dental roots than Caucasians, African Americans, and Asians; and 2. Females have a higher prevalence of short dental roots than males. The experimental groups consisted of 30 Caucasians, 30 His...

BACKGROUND The aim of this study was to measure the distance between the maxillary premolar and molar teeth apices to the buccal cortical bone and evaluate differences in gender and age group, using cone beam computed tomography (CBCT). MATERIAL AND METHODS This retrospective study comprised of 451 premolar and molar teeth of one hundred and thirteen patients who were admitted to Dicle Universi...

Tooth hypersensitivity is a common clinical complaint after dental treatment. Objective: This study presents case report of the use diode laser for treating tooth in patient with cantilever fixed partial denture abutment. Case Report: A 23-year-old female presented to Faculty Dentistry, Umm Al-Qura University Makkah, chief pain deeply carious maxillary right first premolar. The was extracted, a...

Complex and unusual root canal morphology is an often occurring phenomenon. Understanding the unusual root canal morphology contributes to success in endodontic treatment. One such variant root canal morphology is the 'S' shaped or bayonet shaped root canal. This case report discusses endodontic treatment of a maxillary second premolar with an 'S' shaped root canal.

intraosseous migration is an unusual developmental dental anomaly, which demonstrates horizontal movement of unerupted teeth only affecting the permanent dentition of the lower jaw. mandibular second premolar is the most common impacted tooth after the third molars and maxillary canines. distal migration of the second premolar is rare and early loss of the permanent first molar is one of the mo...

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...
