Table 3. Hypothesis test summary .

Serial number	Null Hypothesis	Test	Significance	Decision
1	The categories defined by Clinical Examination Findings: Colour = Inflamed and Healthy occur with probabilities .500 and .500.	One-Sample Binomial Test	.186	Retain the null hypothesis.
2	The categories defined by Clinical Examination Findings: Texture = Stippling Absent and Stippling Present occur with probabilities .500 and .500.	One-Sample Binomial Test	< .001	Reject the null hypothesis.
3	The categories defined by Clinical Examination Findings: Bleeding = no significant bleeding areas recorded and bleeding on probing in some teeth occur with probabilities .500 and .500.	One-Sample Binomial Test	.186	Retain the null hypothesis.
4	The categories defined by Clinical Examination Findings: Recession = Absent and Present occur with probabilities .500 and .500.	One-Sample Binomial Test	< .001	Reject the null hypothesis.
5	The categories defined by Clinical Examination Findings: Pocket Depth = Absent and Present occur with probabilities .500 and .500.	One-Sample Binomial Test	.089	Retain the null hypothesis.
6	The categories of Date of cementation occur with equal probabilities.	One-Sample Chi-Square Test	.156	Retain the null hypothesis.
7	The categories of Post Follow-up Veneer status (i.e.: marginal staining, debonded, chipping) occur with equal probabilities.	One-Sample Chi-Square Test	< .001	Reject the null hypothesis.
