eports of the FNAC’s were reviewed and
compared with the final diagnosis. The
final diagnosis was determined either by
the histopathological examination of the
lesion or the clinical outcome.
Results: Of the 119 FNAC’s performed,
13 were non diagnostic and in 27, the
final diagnosis couldn’t be reached. After
exclusion of those cases, 79 FNAC’s were
compared with the final diagnosis. A
cytological diagnosis of malignancy was
confirmed in 9 cases out of 10 (sensitivity
90%). Cytological diagnosis of benign
tumor was confirmed in 17 out of 24
(sensitivity 71%). Inflammatory and other
non-neoplastic lesions had a concordance
in 43 out of 45 cases (sensitivity 96%).
Cytological diagnosis of benign salivary
gland tumor was confirmed in only 7 out
of 19 cases (sensitivity 37%). Cytological
diagnosis of lymphoma was confirmed in
3 out of 4 cases (sensitivity 75%). All the
5 metastatic carcinomas were accurately
identified by FNAC. Seven cases of salivary
gland malignancies were misdiagnosed as
benign tumors. One lymphoma case was
misdiagnosed as reactive.
Conclusion: While FNAC was reliably
accurate in detecting metastatic
carcinomas to neck lymph nodes, it was
unfortunately unreliable in distinguishing
between benign and primary malignancies
of the major salivary glands. Another pitfall
of FNAC was in distinguishing between
lymphoma and reactive lymphadenitis.

Methods:Twenty edentulous elderly
patients (Cawood class V–VI) participated
in this cross sectional experimental design,
prospective clinical study between 2008
and 2012. All the subjects were over 65
years of age. Conventional dentures were
fabricated for all participants using the
standard method and were allowed to use
them for one year. After data collection,
two implants were placed bilaterally
in the canine region of the mandible
using one surgical technique. After 3
months, overdentures were fabricated
supported by two locator denture housing
attachments. A standardized clinical and
radiographic evaluation was performed
1-week, 0, 6 and 12 months after insertion
of the conventional and implant supported
dentures. Intra-oral radiographs were
made. Patient satisfaction was recorded
using questionnaires using simple Arabic
language. Results were analyzed.
Results: The study indicated statistical
superiority of the implant overdenture as
compared to the conventional one. The
soft tissue response showed a significant
improvement with implant supported
denture therapy. None of the patients
showed any sensory change in lip or
chin region. The pocket depth decreased
significantly whereas the mucosa recession
increased significantly (P = 0.001). After
12 months, there was insignificant bone
loss around the implant (less than 0.2mm).
Patients satisfaction with mandibular
implant-supported overdentures was
recorded as ‘‘great.’’
Conclusion: From our study it was
concluded that implants placed in the interforaminal
region supply a proper base for
the support of mandibular overdentures
in the edentulous patient. In addition
implant retained overdentures result in a
significant increase in patient satisfaction
when compared to conventional dentures.
Objectives: To evaluate the condition of
the supporting and peri-implant tissues
after construction of mandibular implantsupported
dentures opposing conventional
maxillary dentures. The comparative
assessment of patient satisfaction and
preference was also considered.
