OBJECTIVE By date investigations have indicated the presence of stem cells within the pulp tissue of both temporary and permanent human teeth. In the present study, these stem cells were compared in terms of their growth kinetics and culture requirements. MATERIALS AND METHODS Stem cells within the pulp of the human third molar (permanent tooth) and the deciduous incisor (temporary tooth) wer...

AIM The aim of this study was to assess the relative contributions of patient characteristics and radiographic variables to the difficulty of extraction of impacted mandibular third molars in a Nigerian population. METHODS AND MATERIALS Seventy-nine consecutive patients undergoing mandibular third molar extractions were recruited for this prospective cohort study. Specific patient characteris...

RELATED TO DENTAL DEFECTS CAUSING TOOTH LOSS Tooth agenesis is the most prevalent craniofacial congenital malformation in humans. Up to 25% of the population may lose at least one third molar. Agenesis of other permanent teeth, excluding third molars, ranges from 1.6 to 9.6%, depending on the population studied. Primary dentition may also be affected, but with lower prevalence (from 0.5 to 0.9%...

OBJECTIVE Radiographic evaluation of the third molar tooth to determine its position and degree of development is an important part in diagnosis and treatment planning, as well as in forensic dentistry procedures. The objective was to investigate the developmental stages of third molars in relation to chronologic age, gender and location (maxillary/mandibular) in an Iranian population. MATERI...

Bilateral inverted third molar impaction is an extremely rare condition. We reported the case of a 50-year-old female patient with bilateral inverted and impacted maxillary third molars. Both were asymptomatic and pathology free clinically and radiographically. Surgical extraction of these inverted third molars with inaccessible positions requires an aggressive bone removal on the tuberosity bi...

OBJECTIVES Surgical removal of third molars is a regular surgical procedure, which like all operations, may have complications. The purpose of the study was to analyze the incidence of complications and their relationship with the surgical difficulty in a group of 588 patients treated by the same oral and maxillofacial surgeon. STUDY DESIGN This retrospective cohort study consisted of 1699 th...

Removal of an impacted maxillary third molar is a simple and easy procedure for an Oral and Maxillofacial Surgeon. Nevertheless, complications are possible and include infection, facial swelling, trismus, wound dehiscence, root fracture or even orosinusal fistula. Iatrogenic displacement into the infratemporal fossa is frequently mentioned but rarely reported. This anatomical fossa includes sev...

Pain during extraction of impacted mandibular third molars which can occur despite adequate local anesthesia is termed as “escape pain phenomenon”. Recently, it was described during elevation of a mesioangular impacted mandibular third molar and also while curetting an extracted third molar socket. This phenomenon has been overlooked, as it was previously considered secondary to pressure effect...

This study aimed to assess the variability of the lower third molar (tooth 38 and 48) development in Northeast Malaysian population with respect to the side of dentition, to generate age prediction models and to compare the outcome with other studies. A total of 1080 orthopantomograms of Northeast Malaysian population aged between 14 and 25 years (540 males and 540 females) from the Hospital Un...

background and aim of study: long span is seen in many clinical situations, treatment planning options of these cases are difficult and may require: fpd, rpd or isp. each option has its own disadvantages: mechanical, patient relief and cost respectively. this article will evaluate the stress distribution of another treatment option which is adding a single supporting implant to the fpd by using...
