Introduction: Tea is a common beverage among Malaysians. However, tea can stain natural and artificial
teeth due to chromogens, tannins and acid.
Aims and objectives: To study the staining potential of tea between natural teeth and different types of
acrylic resin teeth.
Methodology: This is an in-vitro study carried out on 68 specimen divided into 4 groups namely 1 layer acrylic
resin teeth (1.00), 2 layer acrylic resin teeth (2.00), 3 layer acrylic resin teeth (3.00) and extracted natural teeth
(4.00). The shade of teeth were tested, then stained with black tea (BOH) for a week. Spectrophotometer
was used to measure the colour changes in the respective acrylic resins and teeth to obtain L* a* b* values.
Data was analyzed using ANOVA and paired t -test using SPSS version 22.
Results: A significant difference was found between the groups when compared with p<0.001. For L* ,
group 4 had the highest value (79.0506) . For a* and b*, the mean value for group 2 was the highest (1.1194
and 11.8106 respectively).
Conclusion: Significant changes in staining was found in all the groups. Maximum staining was found
in artificial resin teeth as compared to natural teeth. This may have clinical implications for patients with
dentures, who consume tea regularly.”

Introduction: Torus represents a benign anatomic variation which is a bony prominence occurring in the
hard palate and the lingual aspect of the mandible. Although they are generally asymptomatic, surgical
intervention may be required in certain cases for prosthodontic purposes.
Aims and objectives: To determine the prevalence of maxillary and mandibular torus among patients
visiting the SEGi Oral Health Centre.
Methodology: This is a cross-sectional study based on records of the patients. Data was collected from about
3070 existing folders of patients who visited SEGi Oral Health Centre in the year 2017.Demographic details,
presence of palatal and mandibular tori was recorded using a standard proforma. Data was analysed using
SPSS version 22. Descriptive statistics and chi-square tests were used. p<0.05 was considered statistically
significant.
Results: Out of 3070 patients’ records examined, 751 (24.5%) had palatal tori and 267 (8.7%) had mandibular
tori. Palatal tori was found to be more among female patients (p<0.01), both palatal and mandibular tori
was more prevalent among Chinese ethnicity (p<0.01) and among patients between 31 to 60 years of age
(p<0.01).
Conclusion: Our study showed that almost 30% of the patients had torus. This factor needs to be considered
while treating patients for dentures.
