Singapore Dent J, 2007 Dec;29(1):41-5.

Obstruction remains as an important cause of failure in the eruption of a tooth. In this article, a 15-year-old girl was presented with retained upper left primary canine (63) and first primary molar (64), while the contralateral permanent canine (13) and premolars (14 and 15) have erupted. Upon radiographic examination, a mass which was diagnosed later to be compound odontome was detected. The treatment consisted of surgical removal of the odontome, extraction of the primary canine (63) and left permanent canine (23), and transplantation of the permanent canine (23). The management of this case and the literature related to autotransplantation are discussed.

Singapore Dent J, 1995 Jul;20(1):8-10.

PMID: 9582682

A clinical analysis of 304 cases of pyogenic granuloma (excluding pregnancy tumour) were obtained from the clinical evaluations submitted by clinicians while sending specimens for biopsy. The average age of the patients with pyogenic granuloma was 28.9 years with a peak age incidence in the second decade. More female patients were affected and the lesions present mainly in the Chinese. The majority of the lesions were ulcerated and pedunculated. The lesions had a mean diameter of 10.8 mm with a mean lesion duration of 6.0 months. The gingiva was the prevalent site for these lesions with a greater number being located in the maxilla. The recurrence rate was found to be 14.1%.

PMID: 2487471

Many studies have been reported on radiographic lesion sizes of periapical lesions. However no studies have been reported on prevalences of subjective radiographic features in these lesions except for the early assumption that a periapical cyst usually exhibit a radiopaque cortex. This study is conducted to evaluate the prevalences of several subjective radiographic features of periapical cysts and granulomas in the hope to identify features that maybe suggestive of either diagnosis. The results showed that a regular (circular or semi-circular) radiographic outline is likely to be a periapical cyst while an irregular radiographic outline is not indicative of either a cyst or a granuloma. The association between the regular/irregular radiographic outline and the type of periapical lesion was found to be statistically significant (p less than 0.001). The associations of two other radiographic features and the type of periapical lesion were found to be just statistically significant (p less than 0.01). These features are the symmetry/asymmetry of the radiolucency in relation to the apex and the funnel-shaped/angular-shaped extension of the radiolucency. The widely accepted criteria that the possession of a radiopaque cortex surrounding the radiolucency can discriminate between a periapical cyst and granuloma cannot be statistically supported in this study.

PMID: 3155003

Early-onset periodontitis in children, teenagers and young adults is quite rare. This form of periodontitis progresses very rapidly and cause massive destruction to the periodontium. Various names have been given to this condition since it was first recognised in the 1920s. Through time the nomenclature changed from one to the other. Currently 3 forms of early-onset periodontitis are recognised--i.e. prepubertal periodontitis (PPP), localised juvenile periodontitis (LJP) and rapidly progressive periodontitis (RPP). The clinical features of juvenile periodontitis as it was first described together with that of the present 3 clinical entities mentioned above are presented. Concepts on the aetiology of the disease have also changed through time, and include degenerative process, bacterial infection, defects in the host defense system and heredity. Current thought is that there is an interplay of most of these factors in pathogenesis of the disease. Treatment modalities changed too. At the moment, comprehensive periodontal therapy with meticulous oral hygiene measures seem to be the treatment of choice. Concurrently, systemic tetracycline administration might have some added benefits.

PMID: 15736836

Early orthodontic interventions are often initiated in the developing dentition to promote favourable developmental changes and remove or suppress those that are unfavourable. Early interceptive orthodontics can eliminate or reduce the severity of a developing malocclusion, the complexity of orthodontic treatment, overall treatment time and cost. It also improves self-esteem in the subjects and parental satisfaction. Early detection and appropriate referral of cases requiring interceptive orthodontics are important. However, lack of awareness among school children, parents and primary-care personnel (dental nurses and dental officers) may result in patients not being referred for timely interceptive intervention. This article presents a general view of the scope of interceptive orthodontics that can be carried out in early mixed dentition, i.e. when the permanent incisors and molars are erupting into the oral cavity.

BACKGROUND: Application of principles of electrocautery for hemostasis dates back to prehistoric times. Its modern implementation in various fields of general and head and neck surgeries have been well documented. However its usage in minor oral surgical procedures has gained popularity only recently. Complications associated with electro-surgery in the dental field are relatively rare and there is insufficient literature on its management.

CASE REPORT: We present a case report on management of an electrosurgery induced osteonecrosis involving maxillary alveolus of left premolars.

DISCUSSION: Inadvertent contact of the electrosurgery tip on bone can result in necrosis making it necessary to remove the sequestrum and graft the defect. Platelet rich fibrin in combination with bone grafts have been well documented to provide successful periodontal regeneration.

CLINICAL IMPLICATIONS: Our aim of presenting this report is to create awareness among the health care providers regarding electrosurgical injuries. To our knowledge, this is the first time platelet rich fibrin has been used in the management of intraoral electrosurgical injury. Combining bone grafts with platelet rich fibrin is a good alternative as it can be done with relative ease and predictable outcome.

Adenomatoid odontogenic tumour: a case study with radiographic differential diagnostic considerations

Siar CH, Ong ST, Ng KH

Singapore Dent J, 1996 Jul;21(1):19-22.

PMID: 10597178

Adenomatoid odontogenic tumours (AOT) are benign, hamartomatous odontogenic lesions that not uncommonly mimic a dentigerous cyst radiographically. Such a case as found involving an unerupted left maxillary canine in a 19-year-old Chinese female is described. The differential diagnosis of some common odontogenic cysts and neoplasms occurring in Malaysians, that may present in a dentigerous relationship to an unerupted tooth is discussed. A brief review of the radiographic literature on AOT is also included.

Siar CH, Ng KH, Chia TY

Singapore Dent J, 1990 Dec;15(1):35-7.

PMID: 2097728

Granular cell ameloblastomas are uncommon lesions accounting for about 3-5% of all histologic subtypes of ameloblastoma. The plexiform granular cell odontogenic tumour, on the other hand, is a newly described lesion characterised by a monophasic plexiform pattern of granular cells. This article reports a tumour found occurring in the left mandible of a 67-year-old Indian male which histologically showed features of both the aforementioned lesions.

PMID: 9582689

The disinfective and fixative properties of glutaraldehyde are now widely investigated. Glutaraldehyde is effective against micro-organisms and their spores. Recently, studies have shown the effectiveness of glutaraldehyde against the HIV virus. 2% glutaraldehyde is now recommended for the sterilisation of surgical instruments, operating areas, dental impressions and root canals during endodontic therapy. Studies have also shown that glutaraldehyde is an effective fixative with minimum side effects, limited penetration and quick acting. Pulpotomy studies using glutaraldehyde as the fixative agent produce high success rates. The important feature is the vital pulpal tissue at the apical third suggesting its limited penetration. The small amounts that get distributed systemically are quickly metabolised and excreted in the urine or exhaled as carbon dioxide.

PMID: 16438264

The objectives of this study were to determine the sources of stress among undergraduate dental students, and to compare the sources of stress among the 5 years of undergraduate study, between gender, and with other studies done elsewhere. A total of 325 students across the 5 academic years (88.8% response rate) of the Faculty of Dentistry, Universiti Kebangsaan Malaysia, completed the modified Dental Environment Stress questionnaire. All respondents reported that they experienced some form of stress. The preclinical students reported that examinations and fear of failure caused the most stress. The main stressor for clinical students was clinical training, particularly factors relating to meeting clinical requirements. Female students perceived more stress generally than male students. However, male students were more stressed when faced with factors related to clinical training.

Singapore Dent J, 1995 Jul;20(1):11-5.

PMID: 9582683

A questionnaire survey on cross-infection control was conducted among 1371 professionally trained dentists whose names appeared in the Malaysian Government Gazette of 1990. A 73.1 percent response rate was obtained. About 13 percent of the dentists routinely did not wear gloves during treatment of patients as opposed to 54 percent who routinely did. About 83 percent and 52 percent of dentists wore a mask and eyewear or glasses respectively when carrying out dental procedures. About 93 percent of dentists would use a new sterile needle for each patient and about 40 percent would wipe working surfaces with disinfectant after each patient. The practice of sterilizing handpieces was found to be uncommon as opposed to the sterilization of hand instruments. Variations were observed in some of the infection control measures by gender, seniority in service and employment status. More than one-third of the respondents had experienced puncture wounds during the last month prior to the survey.

Managing complications of radiation therapy in head and neck cancer patients: Part IV. Management of osteoradionecrosis

Ramli R, Ngeow WC, Rahman RA, Chai WL

Singapore Dent J, 2006 Dec;28(1):11-5.

PMID: 17378336

Head and neck cancer is becoming a more recognizable pathology to the general population and dentists. The modes of treatment include surgery and/or radiation therapy. Pretreatment dental assessment should be provided for these patients before they undergo radiation therapy. There are occasions, however, whereby head and neck cancer patients are not prepared optimally and, as a result, they succumb to complicated oral adverse effects after radiation therapy. Osteoradionecrosis (ORN) is a severe debilitating condition that impairs healing due to reduction in vascularity and osteocyte population in the affected bone. This article reviews methods of treatment used to treat ORN such as antibiotics, hyperbaric oxygen therapy, therapeutic ultrasound, surgery, and other modalities.

Minor oral surgery in anticoagulated patients: local measures alone are sufficient for haemostasis

Ramli R, Abdul Rahman R

Singapore Dent J, 2005 Dec;27(1):13-6.

PMID: 16438263

Minor oral surgery in warfarinized patients can be performed without stopping or altering the dose of the drug. Thirty patients underwent various types of oral surgical procedures without interruption of their anticoagulant therapy and their therapeutic international normalized ratio maintained. Local measures such as pressure, packing the sockets with oxidized regenerated cellulose, and suturing were applied. In some patients, tranexamic acid mouthwashes were prescribed to further enhance haemostasis. Four patients had minimal postoperative bleeding in the form of bloodstained saliva, which lasted for 24 hours. This study highlights the importance of local measures in controlling postoperative bleeding in warfarinized patients undergoing minor oral surgical procedures.
