Lower Lip Numbness Due To Peri-Radicular Dental Infection, Wei Cheong Ngeow Dec 1998

Lower Lip Numbness Due To Peri-Radicular Dental Infection, Wei Cheong Ngeow

Wei Cheong Ngeow

Lower lip numbness has always been a sinister symptom. Much has been written about it being the sole symptom of pathological lesions and metastatic tumours in the mandible. It may also be a symptom of manifestations of certain systemic disorders. A case of lower lip numbness resulting from the compression of the mental nerve by a peri-radicular abscess is presented because of the unusual nature of this spread of infection.


Dens Evaginatus On A Wisdom Tooth: A Diagnostic Dilemma. Case Report, Wei Cheong Ngeow, W. L. Chai Oct 1998

Dens Evaginatus On A Wisdom Tooth: A Diagnostic Dilemma. Case Report, Wei Cheong Ngeow, W. L. Chai

Wei Cheong Ngeow

Pericoronitis is the most common odontogenic problem associated with the wisdom tooth in young men and women. Patients may present with problems associated with infection, swelling and pain. However, other associated pathology such as caries, periodontal disease and referred pain from the temporomandibular joint must be investigated when treating pain from the wisdom tooth. The authors wish to present a case in which the pain from a wisdom tooth was due to a fractured dens evaginatus. The importance of this dental anomaly should not be overlooked.


Gaining Access Through A Calcified Pulp Chamber: A Clinical Challenge, W.C. Ngeow, Y. L. Thong Sep 1998

Gaining Access Through A Calcified Pulp Chamber: A Clinical Challenge, W.C. Ngeow, Y. L. Thong

Wei Cheong Ngeow

Dental pulp is prone to dystrophic mineralization; this mineralization can be so extensive that the entire root canal system is obliterated, As a result, root canal treatment can become a difficult if not impossible task, This article presents the endodontic management of a tooth with an obliterated pulp chamber and associated with a discharging sinus in a teenage patient, The role of a calcium hydroxide lining to induce mineralization and cause the obliteration of the pulpal space is also discussed.


Thermocycling As A Means Of Inducing Mechanical Fatigue In Dental Composites, Noor Hayaty Abu Kasim Abu Kasim N.H. May 1998

Thermocycling As A Means Of Inducing Mechanical Fatigue In Dental Composites, Noor Hayaty Abu Kasim Abu Kasim N.H.

Noor Hayaty Abu Kasim Abu Kasim N.H.

The effect of thermocycling on the fatigue behaviour of 5 commercially available dental composites; P50(P)1, Silux Plus(S)2, Heliomolar(H)3, Clearfil Photo Posterior-light activated(CLA)4 and Clearfil Posterior-chemically activated(CC)5 was investigated. One hundred and ten rectangular bar specimens were prepared for each materil and divided into 11 groups of 10 each. Test groups 1-6 were subjected to 0, 250, 500, 750, 1000 and 1000 thermal cycles respectively. Each thermal cycle consisted of 1 minute immersion time of 50 seconds per change. The control groups 7-11 were stored in distilled water at 370c for the equivalent time to complete 250, 500, 750, 1000 and …


Management Of The Fractured Maxillary Tuberosity: An Alternative Method, W.C. Ngeow Mar 1998

Management Of The Fractured Maxillary Tuberosity: An Alternative Method, W.C. Ngeow

Wei Cheong Ngeow

The maxillary tuberosity can fracture during extraction of a molar tooth. If a small bony fragment is affected, the extraction of the tooth and tuberosity continues; however, a conservative approach is advised if the bony fragment is large. In a modified blind surgical technique, the tooth is removed without the fractured bone.


Recurrent Gigantic Pyogenic Granuloma Disturbing Speech And Mastication: A Case Report And Literature Review, M. A. H Ong, W. L. Chai, W.C. Ngeow Mar 1998

Recurrent Gigantic Pyogenic Granuloma Disturbing Speech And Mastication: A Case Report And Literature Review, M. A. H Ong, W. L. Chai, W.C. Ngeow

Wei Cheong Ngeow

A case of gigantic pyogenic granuloma with three recurrences in the lower anterior gingiva is presented. Surgical wide excision of the lesion is the treatment of choice. The tumour must be excised down to the periosteum and the irritants around it removed to avoid recurrence. A contributing factor to the gigantic lesion is hormonal changes during pregnancy. Long-term review for 18 months after the third surgery showed no evidence of recurrence at the surgical site.


The Radiopacity Of Dental Prostheses (Fixed And Removable) On Plain Radiographs-An Experimental Study, Noor Hayaty Abu Kasim Abu Kasim N.H. Jan 1998

The Radiopacity Of Dental Prostheses (Fixed And Removable) On Plain Radiographs-An Experimental Study, Noor Hayaty Abu Kasim Abu Kasim N.H.

Noor Hayaty Abu Kasim Abu Kasim N.H.

The impaction of dental prostheses in either the airway or esophagus is an under-recognized problem which may result in severe morbidity or even mortality. The radio-opacity and the size of fixed and removable dental prostheses in an animal carcass was investigated. Prostheses were placed one at a time in the oro-laryngopharynx or in tho trachea and the esophagus. Lateral radiographs were taken for each prosthesis in site. The radio-opacity and size of the prostheses on the radiograph was graded. Most of the prostheses investigated were radio-opaque though the removable prostheses were more likely to be radiolucent and differ in size. …
