Wei Cheong Ngeow
Microsurgical repair of transected peripheral nerves is compromised by the formation of scar tissue and the development of a neuroma, thereby limiting the success of regeneration. The aim of this study was to quantify histomorphometrically the structural changes in neural tissue that result from repair, and determine the effect of mannose-6-phosphate (M6P), a scar-reducing agent previously shown to enhance regeneration. In anaesthetised C57-black-6 mice, the left sciatic nerve was sectioned and repaired using four epineurial sutures. Either 100 mu L of 600 mM M6P (five animals) or 100 mu L of phosphate-buffered saline (placebo controls, five animals) was injected into …

Wei Cheong Ngeow
We have determined the effect of applying Mannose-6-Phosphate (M6P), a scar reducing agent, to a site of sciatic nerve repair. In anaesthetised C57-Black-6 mice, the left sciatic nerve was sectioned and repaired using 4 epineurial sutures. Either 100 mu l of 600 mM Mannose-6-Phosphate (29 animals), or 100 mu l of phosphate buffered saline as a placebo control (29 animals), was injected into and around the nerve repair site. A further group acted as sham-operated controls. After 6 or 12 weeks of recovery the extent of regeneration was assessed electrophysiologically and the percentage area of collagen staining at the repair …
Decompression Of Inferior Alveolar Nerve: Case Report Comment, W.C. Ngeow
Decompression Of Inferior Alveolar Nerve: Case Report Comment, W.C. Ngeow
Wei Cheong Ngeow
Paresthesia as a result of mechanical trauma is one of the most frequent sensory disturbances of the inferior alveolar nerve. This case report describes surgical treatment for paresthesia caused by a compressive phenomenon within the mandibular canal. The cause of the compression, a broken instrument left in the patient's mouth during previous endodontic therapy, was identified during routine radiography and computed tomography. Once the foreign object was removed by surgery, the paresthesia resolved quickly. This case highlights the potential for an iatrogenic mechanical cause of paresthesia.
Is There A "Safety Zone" In The Mandibular Premolar Region Where Damage To The Mental Nerve Can Be Avoided If Periapical Extrusion Occurs?, W.C. Ngeow
Wei Cheong Ngeow
The mandibular premolars are located close to the mental foramina (Fig. 1). As such, various events affecting these teeth, such as odontogenic infection1 and orthodontic, endodontic, periodontal or surgical misadventure, may result in neurosensory disturbance of the mental nerves.2-4 In one retrospective study, the incidence of mental paresthesia resulting from periapical infection or pathology was 0.96%. In another 0.24% of cases in the same study, mental paresthesia was a complication of root canal treatment (caused by severe overfill in one case and iatrogenic perforation of mechanical instrumentation through the root and into the mental nerve in the second case).1 The …

A Radiographic Study On The Visualization Of The Anterior Loop In Dentate Subjects Of Different Age Groups, W.C. Ngeow, D. D. Dionysius, H. Ishak, P. Nambiar
Wei Cheong Ngeow
The anterior loop is defined as where the mental neurovascular bundle crosses anterior to the mental foramen then doubles back to exit the mental foramen. It cannot be seen clinically but can be detected in 11-60% of panoramic radiographs. As this anatomical structure is important in determining the placement position of endosseous implants in the mandibular premolar region, a pilot study was undertaken to determine its visibility on dental panoramic radiographs in dentate subjects of various age groups. One or more anterior loops were visible in 39 (40.2%) radiographs encompassing 66 sites (34.4%). Interestingly, anterior loops were most commonly observed …

Unusual Tooth Sensation Due To Maxillary Sinusitis--A Case Report, W.C. Ngeow
Wei Cheong Ngeow
Maxillary sinusitis can cause pain or discomfort to the maxillary dentition but no report of patients complaining of a "jumping tooth sensation" during sinusitis has been recorded in the literature. This article presents a case of an unusual localised sensation from a maxillary right second premolar experienced while undergoing root canal treatment. This sensation was felt during walking while the patient was suffering an episode of influenza. This sensation first occurred following debridement of the root canal. However, it persisted even after the root canal had been sealed. A hypothetical explanation of this manifestation is proposed.

Making Your Own Retrograde Carrier, W. L. Chai, W.C. Ngeow
Wei Cheong Ngeow
One of the problems faced by manufacturers is the difficulty in constructing a robust and reliable, angled applicator tip. This can be overcome by handmaking your own retrograde carrier. The applicator tip may be bent to about 50 degrees and, if a kink occurs while bending the tip, it can be replaced easily by a new modified needle. Because the wire used is flexible, it can adapt to the bend without a problem. Narrower carriers can also be made using a 20-G needle, perhaps more suitable for retrograde fillings of molar apices. Because the carrier is designed to be used …
