Dent Traumatol, 2001 Aug;17(4):149-52.

Evidence of traumatized permanent incisors was recorded as part of a national oral health survey of schoolchildren in Malaysia. A total of 4,085 schoolchildren aged 16 years were examined. The prevalence of injury was 4.1% and it was significantly higher in males than females, with a ratio of 2:1. Almost 75% of the subjects had one tooth affected. Out of a total of 200 fractured teeth, 78.0% involved the maxillary central incisors. A high level of untreated traumatized teeth (89%) was noted. However, of the untreated traumatized teeth, only 9% presented with problems such as discoloration of tooth, sinus or abscess formation.

PMID: 7811661

A case of non-vital infected dens invaginatus of the maxillary right lateral incisor with open apex, which presented with pain and swelling is presented. Although root growth and apical closure was achieved using calcium hydroxide, the periapical infection persisted and resolution was only achieved after apical curettage and apicectomy.

Odontostomatol Trop, 1992 Mar;15(1):16-8.

PMID: 1287606

Double teeth or joined teeth have been described under several different terms and the terminology is often confusing. There are several ways in which union of teeth can occur and the terms that are commonly used to describe the condition are fusion and gemination. Although primary double teeth themselves may be regarded as harmless anomalies, its presence can cause some abnormalities to occur in the permanent dentition. Therefore, early diagnosis of the anomaly is of considerable importance.

Aust Orthod J, 1989 Oct;11(2):93-5.

PMID: 2639661

An investigation of the prevalence and distribution of hypodontia was carried out in Malaysian children between the ages of five to fifteen years. Hypodontia occurred in 2.8 per cent of these children. A greater number of females were found to have hypodontia, the ratio of affected females to males is 1.6:1. The teeth most frequently missing were the maxillary lateral incisors followed by the mandibular lateral incisors, then the mandibular second premolars. The aetiology of the condition is discussed. It is noteworthy that studies showing the lower second premolars to be most commonly missing have younger subjects. This suggests delayed development of these teeth in some individuals.

Dent J Malays, 1985 Jan;8(1):9-12.

PMID: 3916997

The problem of dental decay was studied in a sample of 495 Chinese preschool children in Petaling Jaya. The children; 253 males and 242 females ranged in age from 3-6 years. 18.6% of the children was observed to suffer from rampant caries. Only 18.8% were caries free. The dft values ranged from 2.9 +/- 3.12 at 3 years to 5.85 +/- 3.41 at 6 years. The overall mean dft for this group was 4.99 +/- 3.81. Dental treatment was very inadequate. The decayed filled tooth ratio was 6.5:1.

PMID: 2152540

The presence of supernumerary teeth in the premaxillary region may cause a variety of pathological effects. This study was carried out to determine the various aspects of supernumerary teeth in the premaxillary region, particularly the effects of the supernumerary teeth on the permanent incisors and surrounding tissues. Approximately 20 percent of the patients (n = 49) with supernumerary teeth did not present with any abnormality. A high proportion of patients (37.9 percent) had delayed or failure of eruption of permanent teeth and 24.1 percent had rotation or displacement of permanent teeth. Other effects observed were median diastema and cystic changes around the unerupted supernumerary tooth. The high proportion of pathological effects seen showed that early diagnosis of the anomaly is important to intercept damage to the adjacent normal teeth and surrounding tissues. However, no cases of root resorption of the permanent teeth due to the presence of supernumeraries were observed.

The effects of preconception interventions on improving reproductive health and pregnancy outcomes in primary care: A systematic review

Hussein N, Kai J, Qureshi N

Eur J Gen Pract, 2016 Mar;22(1):42-52.

PMID: 26610260 DOI: 10.3109/13814788.2015.1099039

BACKGROUND: Reproductive health and pregnancy outcomes may be improved if the reproductive risk assessment is moved from the antenatal to the preconception period. Primary care has been highlighted as an ideal setting to offer preconception assessment, yet the effectiveness in this setting is still unclear.
OBJECTIVES: To evaluate the effectiveness of preconception interventions on improving reproductive health and pregnancy outcomes in primary care.
METHODS: MEDLINE, CINAHL, EMBASE and PsycINFO databases were searched from July 1999 to the end of July 2015. Only interventional studies with a comparator were included, analysed and appraised systematically, taking into consideration the similarities and differences of the participants, the nature of interventions and settings.
RESULTS: Eight randomized controlled trials were eligible. Preconception interventions involved multifactorial or single reproductive health risk assessment, education and counselling and the intensity ranged from brief, involving a single session within a day to intensive, involving more than one session over several weeks. Five studies recruited women planning a pregnancy. Four studies involved multifactorial risks interventions; two were brief and the others were intensive. Four studies involved single risk intervention, addressing folate or alcohol. There was some evidence that both multifactorial and single risk interventions improved maternal knowledge; self-efficacy and health locus of control; and risk behaviour, irrespective of whether brief or intensive. There was no evidence to support reduced adverse pregnancy outcomes. One study reported no undue anxiety. The quality of the studies was moderate to poor.
CONCLUSION: The evidence from eligible studies is limited to inform future practice in primary care. Nevertheless, this review has highlighted that women who received preconception education and counselling were more likely to have improved knowledge, self-efficacy and health locus of control and risk behaviour. More studies are needed to evaluate the effects on adverse pregnancy outcomes.

Dental anomalies in the primary dentition: distribution and correlation with the permanent dentition

Nik-Hussein NN, Abdul Majid Z

J Clin Pediatr Dent, 1996;21(1):15-9.

PMID: 9161200

The study consisted of analysis of all cases of anomalies in the primary dentition that were seen or treated by the authors in the Department of Children's Dentistry and Orthodontics. A total of 79 occurrences of anomalies was seen in 65 children. The anomalies detected were double teeth, hypodontia and supernumerary teeth. Radiographic examinations of the affected children showed that over 60% of the cases with anomalies in the primary dentition are associated with anomalies of the succadeneous permanent dentition. All subjects with hypodontia of the primary dentition presented with hypodontia of the permanent dentition. However, anomalies of the permanent dentition were seen in 59% of subjects with primary double tooth and 50% of subjects with primary supernumerary tooth.

PMID: 3270565

Enamel defects were studied in a group of 11-12 year-old children in a fluoridated area using the DDE index. The mouth prevalence of this condition was 72.5 per cent with a tooth prevalence of 40.4 per cent. Enamel opacities accounted for 96.5 per cent of the total condition of which the diffuse patchy type predominates. The defects on the affected posterior teeth occurred most commonly on both the buccal and lingual/palatal surfaces, with most defects being located in the incisal one-half, gingival one-half and occlusal simultaneously. In the affected incisors, the highest proportion of defects affected the buccal surface only, with the most frequent location being the incisal one-half and gingival one-half simultaneously. In 20.9 per cent of the affected subjects, there was a 100 per cent tooth involvement.

Med J Malaysia, 2017 06;72(3):157-164.

PMID: 28733563 MyJurnal

BACKGROUND: Hyperlipidaemia is a significant risk factor for cardiovascular disease. However, adherence to lipidlowering therapy is often unsatisfactory due to a combination of patient factors, therapy, socio-economic and health system-related factors.

AIMS: to identify the prevalence of adherence to lipidlowering therapy, the factors contributing to non-adherence and knowledge regarding hyperlipidaemia and its' treatment among Malaysian patients with hyperlipidemia.

METHODS: A quantitative study using a cross-sectional survey was carried out in an urban primary care clinic in August 2015. Patients on lipid-lowering therapy for ≥ 1 year aged ≥ 18 years were selected using simple random sampling. consenting patients answered a selfadministered questionnaire (in Malay/English) which included socio-demographic profile, hyperlipidaemia profile, adherence to lipid-lowering therapy (using the Morisky Medication Adherence scale-8; score ≥ 6 taken as adherent), reasons leading to non-adherence, knowledge regarding hyperlipidaemia and its' treatment, and use of non-allopathic medicine.

RESULTS: the response rate was 90.7%. the prevalence of adherence to lipid-lowering therapy was 82.4%. "the most common reasons for non-adherence was being worried about side effect of lipid-lowering agent (71.4%), followed by the need to take too many drugs in a day (61.4%) and negative influences by friends, relative and mass media (60%)". Factors associated with non-adherence include male gender, on longer duration of therapy, less frequency of follow-up, less number of follow-up clinics, taking medication at night/random timing and having lower knowledge scores.

CONCLUSION: Overall the prevalence of adherence was high in patients with hyperlipidaemia. Interventions to boost adherence should target those who were identified as nonadherent.

Two to three percent of stone disease cases occur in the paediatric age group. It is common in some parts of the world, such as in Turkey, India and Thailand. More than 50 percent of stones in children are still managed through open surgery. Ureteroscopic intervention for children remains a challenging treatment option. However, in contemporary urology practice, this mode of intervention is becoming more common. In this retrospective study, we reviewed our experiences with ureteroscopy and pneumatic lithotripsy in the paediatric and adolescent age group.

Dental abnormalities of a long-term survivor of a childhood hematological malignancy: literature review and report of a case

Zarina RS, Nik-Hussein NN

J Clin Pediatr Dent, 2005;29(2):167-74.

PMID: 15719924

The treatment of haematological malignancy is multimodal and involves chemotherapy, radiotherapy and/or bone marrow transplants. With the advancement in cancer therapy, there is an increase in the survival of many children with childhood haematological malignancy. In addition, the late effect of the oncology treatment to the orofacial and dental development becomes significant in terms of the potential clinical impact that may affect the quality of life of the survivor. The severity of the long-term effects is dependent on the age of the child at initiation of treatment and whether chemotherapy is combined with radiation or not. The dental treatment may become more complex if the patient requires advanced restorative dental care and the roots malformation may complicate orthodontic treatment. Therefore these patients may require a scheduled careful preventive programme, long-term follow up, with prophylactic treatment and intervention at appropriate time to minimize the consequences of the disease and the given therapy.

PMID: 10597176

Two hundred and twenty-nine children aged 12-15 years who were continuous residents of Penang island, in the north of Peninsular Malaysia were examined for caries and enamel defects. Caries prevalence was 82.2% with a DMFT score of 3.4 and DMFS score of 4.9; there were very few missing teeth and very little untreated caries in the population examined. Majority of DF (decayed/filled) lesions were pits and fissures with approximal and smooth surfaces relatively caries free. The prevalence of enamel defects was 76.4% with 19.1% of all teeth examined being affected. More posterior than anterior teeth were affected by enamel defects just as there were more maxillary than mandibular teeth affected by enamel defects. Diffuse patchy opacities were the most common defect diagnosed and this was found in 60.2% of the population examined. A bilateral distribution of diffuse patchy opacities was seen in 41.5% of the population examined. Tooth surfaces with enamel defects were no more susceptible to caries than defect-free surfaces.

The prevalence and distribution of enamel defects in 11-12 year old Malaysian schoolchildren

Nik-Hussein NN, Razak IA

Ann Acad Med Singap, 1989 Sep;18(5):591-3.

PMID: 2619248

The prevalence and symmetrical distribution of enamel defects were studied in 218 Malaysian school children aged 11-12 years old. The tooth prevalence of enamel defect was 40.3 per cent. The first permanent molars were the most severely affected, whereas the lower incisors were the least severely affected. Overall there was no sex difference. Distribution of symmetry was assessed between the right and left tooth pairs as well as for upper and lower teeth. A higher proportion of symmetry was observed for the right and left tooth pairs and the lingual surfaces showed a greater percentage of bilateral distribution.
