The aim of this study was to evaluate the quantitative amount
of apically extruded debris after endodontic retreatment using
three retreatment rotary systems D-RaCe, R-Endo, and
EdgefileXR in the teeth obturated by two techniques (single
cone and continuous wave compaction). Sixty human
mandibular premolars with single straight root canals were
prepared by 2Shape endodontic rotary system with file size
(25/0.04). After that, samples were divided into two groups
according to the technique of obturation used (n=30/group):
A: single cone and B: continuous wave compaction. Then,
further random subdivision for each group into three sub
groups according to the system used for retreatment
(n=10/group) as follow: A1,B1:D-RaCe, A2,B2:R-Endo, and
A3,B3: EdgefileXR. Preweighed Eppendorf tubes were used
to collect the apical extruded material during endodontic
retreatment. Then, Eppendorf tubes were stored in an
incubator at 68C for 5 days. The weight of extruded debris
was calculated by subtracting the weight of the empty tube
from the weight of the tube containing the extruded debris.
Data were analyzed statistically using one way ANOVA
analysis of variance and post hoc Duncan test. EdgeFileXR
and R-Endo were significantly not different, but significantly
different from D-race in two obturation technique. Also,
result showed that the same system exhibited no difference in
both obturation techniques. All retreatment techniques
resulted in apical extrusion debris. Also, it was concluded that
the techniques of obturation had no significant effect in the
amount of apical extruded debris by different retreatment
systems used in this study.

Diagnosis is the corner stone & entry to the treatment of
lesions or conditions. Because misdiagnosis leads to incorrect
treatment. It is very important to understand the distribution
between the most common misdiagnosis nonmalignant
lesions& conditions in the maxillofacial region as apart of
whole misdiagnosis. Decrease patient complaining. Evaluate
the most common misdiagnosis lesions& conditions in
maxillofacial region. Decrease load to hospitals& clinics&
decrease infections. The data collected by standardized
formula for all patients& different patient clinical,
radiological examination & methods used to confirm the
diagnosis. Total no. are 30 patients, misdiagnosis lesions&
conditions
13% (Sinusitis or dental pain), 20%
(submandibular Lymphadenitis. or Sialadenitis), 20%
(Otalgia).
10%(Psychopath),10%(Trigeminal
neuralgia)
,7%(migraine) ,7%( maxillary sinusitis),13%(submandibular
saialidinitis). the true diagnosis was 13%,( Oroantral
fistula),20%(oro-Cutaneous fistula),20%(Tmj pain),10%(Tmj
dislocation),10%(dental pain),7%(dental pain),7%(Maxillary
sinus cyst),13%(submandibular Salivary gland stone). The
more unorganized medical &or surgical branches interference
within region may lead to these misdiagnosis results. Poor
educated patients, doctor’s decision with inadequate
examination& investigation participate in increase patients
complaining.

Background: Oral Candidiasis is a wide opportunistic
infection of the mouth due to an overgrowth of Candida
species, the most being Candida albicans. Its harmless
commensally organism inhabiting the mouth, but it will
change into a pathogen, invade tissue, and cause acute and
chronic diseases. The predisposing factor for infection with
Candida was dentures in about sixty-five percentages of older
peoples who are wearing full upper dentures. Objective: This
research aims to determine the sex distribution of fungal
infection in corresponding with fungal infection among
groups (acrylic and metal denture base). Patients &Methods:
Sixty-eight patients attend the private dental clinic were
subjected to usual dental treatment. They were divided into
two groups: group 1: included 43 (24 females and 19 males)
with acrylic denture base wearers. As well as, group 2: metal
denture base wearers in 25 (10 females and 15 males).
Questionnaire Paper to determine demographic data include,
if patient take any fungal or antibiotic or not (treated and non
treated) and would obtain from the patients by including sex,
age, and nocturnal wear. Result: The results in this study
found that the prime etiology of Candida growth was the
prosthesis materials itself. Sixty-five percent of the wearers of
dentures showed Candida growth, while thirty-five percent of
patients who had their dentitions showed Candida growth that
the appliances are the dominant etiological factors in the
growth of Candida other local factors should be considered.

Introduction: Osseo integrated dental implant represents an
advance management in modern dentistry, with high success
rates. Despite that, several complications involve dental
implants may still happen and dental surgeons should be
attentive to such problem, to prevent implant failures and
biomechanical problems. One of the most serious late implant
complications is the fracture of implant fixture. It can be a
challenge for dentists to determine the etiology of fixture
fractures. Aim of study: Evaluate the effect of some implant
parameters, such as length, diameter and position, on the
occurrence of fixture fracture and to determine the incidence
of fractures reported in 5-10 years of fallow up. Materials and
methods: Clinical retrospective study included 439 implants
made of titanium alloy(Ti-6Al-4V) placed in 192 Iraqi
patients; 103 male patients and 89 female patients with
partially and completely edentulous areas had consulted the
implant department at Al- Elwiya specialized dental center in
Iraq. Results: In this study 439 fixtures distributed in
192patients; 53, 6% was male patients; 46.3% female
patients.3 fixtures fracture reported in this study represent
1.5% in relation to total number of patients. 0.6% of the 439
fixtures installed. 71 fixtures 16.1% supported prosthesis with
Pontics; that reported 3 fixtures fracture 4.2%, while 368
fixtures 83.8% supported prosthesis without Pontics in which
no
fracture
of
fixtures
were
recorded.
Discussion &Conclusion: Fracture of Osseo integrated dental
implants is a late complication, it has low incidence, the
fracture of dental implants fixture are multifactorial, and the
most common cause for fracture is the biomechanical or
physiologic overload.

Odontogenic infections one of the most common diseases in
the
oral and maxillofacial region. Precise &careful
management of such patients very important. Poor
management of odontogenic infection may leads to serious
Complications in the maxillofacial region. Aims of the study.
Hasten & facilitate patient recovery. Evaluate the most
common poor management complication in maxillofacial
region. Patients and methods. Sample of 20 patients
complaining of poor management odontogenic infections.
The data obtained from patients attending maxillofacial clinic.
Same data collection formula for all patients. Results. The
complications was, (10%) Buccal space abscess. (45%)
Submandibular abscess. (10%) Submassetric abscess. (20%)
Ludwig’s angina. (10%) Supra sternal abscess. (5%)
Necrotizing fasciitis Pt no. complaining according to Poor
type of treatment was (35%) Antibiotics only. (15%)
Aspiration of abscess &Antibiotics. (35%) Inadequate abscess
drainage &Antibiotics. (10%) Remove the cause only without
fallow up. (5%) Extraction of non-causative tooth.
Conclusion. Poor education, patient careless (neglected&
poor oral hygiene), inadequate& poor management planning
of cases May leads to these complications results.

Background: The awareness and demand for quality of dental
treatment is relatively increasing in recent generation and
more so, as far as aesthetics are concerned, along with other
functions of the prosthesis. In treating partially edentulous
mouth, it requires more attention, principally for esthetics, in
design. While achieving the goal, the components which are
incorporated in removable partial denture may result in
unsightly appearance. Case Description: A 77 year old patient
reported to the replacement of his missing teeth for which a
conventional maxillary complete denture and cast removable
partial denture with precision attachments were planned to
construct. Extra coronal resilient attachment was planned to
re-claim support and thereby regain of lost esthetics in the
mandibular arch. Conclusion: Use of precision attachment has
amplified the aspects of retention and particularly, esthetics
when compared to conventional removable partial dentures.
