The preliminary investigation was carried out to assess the severity of malocclusion between two centres, the dental schools in Leeds, United Kingdom and Kuala Lumpur, Malaysia. A total of 99 study models were analysed using the Index ofOrthodontic Treatment Need (lOIN). Thestudy models were ofpatients aged 8to 15years, equally distributed between male and female patients taken from the undergraduate and staff clinics. Forty nine and fifty study models were analysed at the Leeds Dental School and FacultyofDentistry,University ofMalaya,respectively.Fromthisobservation, it appeared that the sample of patients treated at the Faculty of Dentistry, Kuala Lumpur presented approximately 25%higher with casesin the severe end of the malocclusion based on the dental health component and almost 70%more with the aesthetic component. Factors contributing to this finding are discussed.

Integrating spectrophotometric and XRD analyses in the investigation of burned dental remains

Rahmat RA, Humphries MA, Austin JJ, Linacre AMT, Raven M, Self P

Forensic Sci Int, 2020 May;310:110236.

PMID: 32172179 DOI: 10.1016/j.forsciint.2020.110236

Heat alters colour and crystallinity of teeth by destruction of the organic content and inducing hydroxyapatite crystal growth. The colour and crystallite changes can be quantified using spectrophotometric and x-ray diffraction analyses, however these analyses are not commonly used in combination to evaluate burned dental remains. In this study, thirty-nine teeth were incinerated at 300-1000 °C for 15 and 30 min and then measured using a spectrophotometer and an x-ray diffractometer. Response variables used were lightness, L*, and chromaticity a* and b* and luminance (whiteness and yellowness) for colour, and crystal size for crystallinity. Statistical analysis to determine the attribution of these variables revealed yellowness and crystal size were significantly affected by temperature (p < 0.05), whilst duration of heat-exposure showed no significant effect. This study suggests the inclusion of both spectrophotometric and x-ray diffraction in investigating thermal-heated teeth is useful to accurately estimate the temperature teeth are exposed to.

The habit of chewing betel quid has been practised since ancient times. Although the world has gone through modernization, a significant proportion of people still practices this habit. Substantial evidence has shown that betel quid chewing is associated with the occurrence of oral cancer and precancerous lesions, which has a tremendous psychosocial impact on an individual's life. Thus it becomes significantly important to dentistry to look into this matter. Since betel quid chewing is one of the causes of oral cancer, effort in cha~ging this habit is essential. This article addresses this issue.

To explore the association between social
support and stress levels in preclinical and clinical dental
students in Malaysia. Method: A cross sectional survey
of dental undergraduate students was conducted at the
Faculty of Dentistry, University of Malaya, Universiti
Kebangsaan Malaysia and Universiti Sains Malaysia.
Stress was measured using the Dental Environment Stress
(DES) questionnaire. A DES-32 item was used to measure
stress for the clinical students and DES-16 item for the
preclinical students. Four questions were used to measure
social support. The total stress scores were standardized
for comparison purposes. Results: A total of 357 (79.7%)
preclinical and 417 (71.8%) clinical undergraduate dental
students responded to the questionnaires. The clinical
students experienced higher stress [mean standardized
DES score = 72.63, SD = 10.64] than preclinical students
[mean standardized DES score = 70.19, SD=12.01]. The
two most stressful items reported by preclinical students
were “fear of failing” and “examination and grades”.
Among clinical students, the two most stressful items related
to academic were “completing course requirement” and
“fear of failing course” and items related to clinical session
were “fear of being barred due to the clinical schedule”
and “patients late or absent”. Multiple regression analyses
revealed that low stress levels among preclinical students
were significantly associated to a lot of contact with
students of the same course. Conclusion: To some extent,
social support does play a role in explaining differences in
perceived stress, in particular among preclinical students.

Dentistry has searched for an ideal material to place in osseous defects for many years. Endogenous bone replacement has been the golden standard but involves additional surgery and may be available in limited quantities. Also, the exogenous bone replacement poses a risk of viral or bacterial transmission and the human body may even reject them. Therefore, before new biomaterials are approved for medical use, mutagenesis systems to exclude cytotoxic, mutagenic or carcinogenic properties are applied worldwide. The present preliminary study was carried out in five male New Zealand white rabbits (Oryctolagus cuniculus). Porous form of synthetic hydroxyapatite granules (500 mg), manufactured by School of Materials and Mineral Resources Engineering, Universiti Sains Malaysia, Penang, was implanted in the femur of the rabbits. Blood samples were collected prior to implantation and one week after implantation. The blood was cultured in vitro and the cell division was arrested at metaphase using colcemid. This was followed by the hypotonic treatment and fixation. Then, the chromosomes were prepared and stained for analysis. The modal chromosome number of rabbit (Oryctolagus cuniculus) was found to be 2n=44. The mean mitotic index values prior to and after implantation were 3.30 ± 0.66 and 3.24 ± 0.27 per cent respectively. No gross chromosome aberrations, both numerical and structural were noticed either prior to or after implantation of the biomaterial. These findings indicate that the test substance, synthetic hydroxyapatite granules does not produce gross chromosome aberrations under the present test conditions in rabbits.

Regression equations for sex and population detection using the lip print pattern among Egyptian and Malaysian adult

Abdel Aziz MH, Badr El Dine FM, Saeed NM

J Forensic Leg Med, 2016 Nov;44:103-110.

PMID: 27743546 DOI: 10.1016/j.jflm.2016.10.003

INTRODUCTION: Identification of sex and ethnicity has always been a challenge in the fields of forensic medicine and criminal investigations. Fingerprinting and DNA comparisons are probably the most common techniques used in this context. However, since they cannot always be used, it is necessary to apply different and less known techniques such as lip prints.

AIM OF THE WORK: Is to study the pattern of lip print in Egyptian and Malaysian populations and its relation to sex and populations difference. Also, to develop equations for sex and populations detection using lip print pattern by different populations (Egyptian and Malaysian).

SUBJECTS AND METHODS: The sample comprised of 120 adults volunteers divided into two ethnic groups; sixty adult Egyptians (30 males and 30 females) and sixty adult Malaysians (30 males and 30 females). The lip prints were collected on a white paper. Each lip print was divided into four compartments and were classified and scored according to Suzuki and Tsuchihashi classification. Data were statistically analyzed.

RESULTS: The results showed that type III lip print pattern (intersected grooves) was the predominant type in both the Egyptian and Malaysian populations. Type II and III were the most frequent in Egyptian males (28.3% each), while in Egyptian females type III pattern was predominant (46.7%). As regards Malaysian males, type III lip print pattern was the predominant one (41.7%), while type II lip print pattern was predominant (30.8%) in Malaysian females. Statistical analysis of different quadrants showed significant differences between males and females in the Egyptian population in the third and fourth quadrants. On the other hand, significant differences were detected only in the second quadrant between Malaysian males and females. Also, a statistically significant difference was present in the second quadrant between Egyptian and Malaysian males. Using the regression analysis, four regression equations were obtained.

Fulltext The phenomenological approach in dentistry - a narrative review

Vasthare R, Lim Y R A, Bagga A, Nayak PP, Bhat B, S S

Int J Qual Stud Health Well-being, 2024 Dec;19(1):2341450.

PMID: 38634343 DOI: 10.1080/17482631.2024.2341450

PURPOSE: Phenomenology is a branch of philosophy that focuses on human lived experience. Illness including dental diseases can affect this living experience. Within the dental literature, there is very little reported on the use of phenomenology compared to other healthcare sciences. Hence, the aim was to review the literature and provide an overview of various applications of phenomenology in dental research.

METHODS: This study was a narrative review using literature in the last 10 years identified by web-based search on PubMed and Scopus using keywords. A total of 33 articles that were closely related to the field and application in dentistry were included. The methodology, main results, and future research recommendations, if applicable, were extracted and reviewed.

RESULTS: The authors in this study had identified several areas such as orofacial pain and pain control research, dental anxiety, dental education, oral healthcare perceptions and access, living with dental diseases and dental treatment experience in which the phenomenological method was used to gain an in-depth understanding of the topic.

CONCLUSIONS: There are several advantages of using the phenomenological research method, such as the small sample size needed, the diverse and unique perspective that can be obtained and the ability to improve current understanding, especially from the first-person perspective.

Feedback on satisfaction with dental care is vital for continuous improvement of the service delivery process and outcome. The objective of this study was to assess the satisfaction with school dental service (SDS) provided via mobile dental squads in Selangor, Malaysia, under 4 domains of satisfaction: patient-personnel interaction, technical competency, administrative efficiency, and clinic setup using self-administered questionnaires. Among the 607 participants who had received treatment, 62% were satisfied with the services provided. In terms of domains, technical competency achieved the highest satisfaction score, whereas clinic setup was ranked the lowest. As for items within the domains, the most acceptable was "dental operator did not ask personal things which were not dentally related," whereas privacy of treatment was the least acceptable. In conclusion, whereas children were generally satisfied with the SDS, this study indicates that there are still areas for further improvement.
