The mean age of participants in Group A was 41.94 ± 13.21 years (range 18–65 years) and in Group B was 42.81 ± 13.16 years (range 18–65 years). The two groups were statistically comparable for age (independent t-test, p > 0.05), confirming effective randomization. This age distribution is consistent with the peak prevalence of dentinal hypersensitivity reported in the third through sixth decades of life, as documented by Addy M (Int Dent J, 2002) and the systematic review of Favaro Zeola L et al. (J Dent, 2019) — which reported the highest DH prevalence between 20 and 50 years.(is it required here or in discussion) Regarding gender distribution, females were the predominant gender in both groups: Group A comprised 22 females (64.7%) and 12 males (35.3%); Group B comprised 23 females (63.9%) and 13 males (36.1%). The female-to-male ratio was approximately 1.8:1 in both groups, with no statistically significant inter-group difference (Chi-Square, p > 0.05). The higher representation of female participants is consistent with published prevalence data indicating greater healthcare-seeking behaviour for dental conditions among women, as well as the greater prevalence of DH in females noted by Rees JS (IJDR, 2000) and Gillam DG et al. (Community Dent Health, 1997). .(is it required here or in discussion) graph Figure 1: Age Distribution Group A vs Group B.

Here is a clean, thesis-ready Results and Observations write-up for Section 1.1:

1.1 Age and Gender Distribution

Table 1.1 presents the demographic profile of both study groups with respect to age and gender.
The mean age of participants in Group A (Test) was 41.94 ± 13.21 years (range: 18–68 years), and in Group B (Control) was 42.81 ± 13.16 years (range: 18–69 years). No statistically significant difference was observed between the two groups for age (independent t-test, p > 0.05), confirming effective baseline randomization and demographic comparability.
Regarding gender distribution, females were predominant in both groups. Group A comprised 22 females (64.7%) and 12 males (35.3%), while Group B comprised 23 females (63.9%) and 13 males (36.1%). The female-to-male ratio was approximately 1.83:1 in Group A and 1.77:1 in Group B. Inter-group comparison revealed no statistically significant difference in gender distribution (Chi-Square test, p > 0.05).
Figure 1 illustrates the age distribution across both groups, confirming comparable profiles with a mean age of approximately 42 years and female predominance of approximately 64% in each group.
Overall, both groups were well-matched for age and gender, ensuring that any observed differences in outcomes could be attributed to the intervention rather than demographic confounders.

Regarding Your Two Parenthetical Queries

"(Is it required here or in discussion?)" — answered separately for each point:
1. Age distribution and DH peak prevalence (Addy 2002, Favaro Zeola 2019): Keep a brief mention in Results — one sentence stating that the observed age range corresponds to the known peak prevalence of dentinal hypersensitivity. The fuller elaboration with multiple citations belongs in the Discussion, where you contextualise your findings against the literature.
Suggested sentence for Results: "The observed age distribution, predominantly within the third to sixth decades of life, is consistent with the reported peak prevalence of dentinal hypersensitivity in this age group."
2. Female predominance and healthcare-seeking behaviour (Rees 2000, Gillam 1997): This interpretive point — explaining why females are over-represented — belongs entirely in the Discussion, not in Results. The Results section should only report what was observed (the ratio and p-value), without inferring reasons. Move the citations by Rees JS and Gillam DG to your Discussion under the heading of gender distribution and DH prevalence.

The majority of participants in both groups were married: Group A — 27 (79.4%); Group B — 30 (83.3%). Secondary education (Class 9–12) was the most common educational level: Group A — 14 (41.2%); Group B — 15 (41.7%). The occupation most frequently observed in both groups was homemaker: Group A — 20 (58.8%); Group B — 21 (58.3%), reflecting the largely semi-urban patient population attending the outpatient department. Service-sector employment was the second most common occupation in both groups (Group A: 7, 20.6%; Group B: 7, 19.4%). Regarding socio-economic status (SES) assessed by the modified Kuppuswamy scale, Middle SES was the dominant category in Group A (17 participants, 50.0%) while Lower Middle SES was dominant in Group B (15 participants, 41.7%). Upper Middle SES accounted for 11.8% of Group A and 16.7% of Group B. No participants from the Upper SES category were enrolled, consistent with the socio-economic profile of the outpatient department catchment area. No statistically significant difference was observed between groups for marital status, education, occupation, or SES (all p > 0.05).

1.2 Socio-Demographic Profile

Table 1.2 summarises the socio-demographic characteristics of both study groups across four parameters: marital status, education level, occupation, and socio-economic status (SES).
Marital Status: The majority of participants in both groups were married — 27 (79.4%) in Group A and 30 (83.3%) in Group B. Unmarried participants accounted for 7 (20.6%) in Group A and 6 (16.7%) in Group B. No statistically significant difference was observed between the groups (Fisher's Exact test, p > 0.05).
Education Level: Secondary education (Class 8–10) was the most frequently reported educational level in both groups — 14 participants (41.2%) in Group A and 15 participants (41.7%) in Group B. Graduate and above was the next predominant category in Group A (9, 26.5%), while primary education (up to Class 7) was more common in Group B (8, 22.2%). Higher secondary education (Class 11–12) accounted for 5 (14.7%) in Group A and 7 (19.4%) in Group B. The inter-group difference in educational distribution was not statistically significant (Chi-Square test, p > 0.05).
Occupation: Homemaker was the most prevalent occupational category in both groups — 20 participants (58.8%) in Group A and 21 participants (58.3%) in Group B, reflecting the semi-urban outpatient population of the study centre. Service-sector employment was the second most common category in both groups (Group A: 7, 20.6%; Group B: 7, 19.4%). Labourer, business, and farmer categories were represented in smaller proportions across both groups, with no substantial inter-group disparity. No statistically significant difference was observed in occupational distribution between the two groups (Chi-Square test, p > 0.05).
Socio-Economic Status: SES was assessed using the modified Kuppuswamy scale. In Group A, the Middle SES category was predominant (17 participants, 50.0%), followed by Lower Middle (13, 38.2%) and Upper Middle (4, 11.8%). In Group B, Lower Middle SES was the most common category (15 participants, 41.7%), followed by Middle (15, 41.7%) and Upper Middle (6, 16.7%). No participants from the Upper SES category were enrolled in either group, consistent with the socio-economic profile of the outpatient department catchment area. The inter-group difference in SES distribution was not statistically significant (Chi-Square test, p > 0.05).
Figure 2 depicts the distribution of all four demographic parameters across both groups, confirming broadly comparable profiles.
Overall, both groups were well-matched across all socio-demographic variables. The absence of statistically significant differences (p > 0.05 for all comparisons) confirms that the two groups were homogeneous at baseline, thereby minimising the influence of socio-demographic confounders on study outcomes.

Note on Discussion Placement

The observation regarding homemaker predominance reflecting a semi-urban OPD catchment population is an interpretive remark. A brief mention is acceptable in Results as contextual explanation, but any elaboration on how SES or occupation may influence oral hygiene practices, dental awareness, or treatment-seeking behaviour should be reserved for the Discussion section.

Prakriti assessment was conducted using the standard Prakriti Pariksha methodology documented in Ashtanga Hridayam and the standardised Prakriti assessment tool. The distribution of dominant Prakriti types is presented in Table 1.3 and Figure 3. Vata-Pitta and Pitta-Kapha were the two dominant dual-Dosha Prakriti types in both groups. In Group A, Vata-Pitta Prakriti accounted for 10 participants (29.4%) and Pitta-Kapha for 10 participants (29.4%) — together comprising 58.8% of Group A. In Group B, Vata-Pitta and Pitta-Kapha were equally distributed at 11 participants each (30.6% each) — together comprising 61.2% of Group B. Vata-Kapha Prakriti accounted for 20.6% of Group A and 11.1% of Group B. Pure Vata, pure Pitta, and pure Kapha Prakriti types were less commonly represented in both groups. Sama Prakriti (balanced tri-dosha constitution) was observed in 2 participants (5.6%) in Group B and none in Group A. The predominance of dual-Dosha Prakriti types — particularly those involving Vata (Vata-Pitta and Vata-Kapha combined = 50.0% Group A; 41.7% Group B) — is clinically significant in the Ayurvedic framework. Dantaharsha is classified as a Vataja or Vata-Pittaja Danta Roga in classical texts (Sushruta Samhita NS 16/3; A.H. U. 22/13), and the predominance of Vata-dominant Prakriti types in the enrolled population supports the classical aetiological understanding of the condition. Both groups showed comparable Prakriti distributions (Chi-Square, p > 0.05).

1.3 Prakriti Distribution

Prakriti assessment was conducted using the standard Prakriti Pariksha methodology as documented in Ashtanga Hridayam, employing a standardised assessment tool. The distribution of dominant Prakriti types across both groups is presented in Table 1.3 and Figure 3.
Dual-Dosha Prakriti types were predominant in both groups. Vata-Pitta and Pitta-Kapha were the most frequently observed constitutions — each accounting for 10 participants (29.4%) in Group A and 11 participants (30.6%) in Group B, together comprising 58.8% of Group A and 61.2% of Group B. Vata-Kapha Prakriti was present in 7 participants (20.6%) in Group A and 4 participants (11.1%) in Group B.
Among pure single-Dosha types, Pitta Prakriti was observed in 4 participants (11.8%) in Group A and 1 participant (2.8%) in Group B; Vata Prakriti in 2 (5.9%) and 4 (11.1%); and Kapha Prakriti in 1 (2.9%) and 3 (8.3%) respectively. Sama Prakriti (balanced tri-Dosha constitution) was observed in 2 participants (5.6%) in Group B and none in Group A.
Collectively, Vata-containing Prakriti types (Vata-Pitta + Vata-Kapha + pure Vata) accounted for 50.0% of Group A and 41.7% of Group B. No statistically significant inter-group difference was observed in Prakriti distribution (Chi-Square test, p > 0.05), confirming baseline comparability.

Note on Discussion Placement

The paragraph linking Vata-dominant Prakriti predominance to the classical Ayurvedic aetiology of Dantaharsha (Vataja / Vata-Pittaja Danta Roga — Sushruta Samhita NS 16/3; A.H. U. 22/13) is interpretive and belongs in the Discussion. In the Results section, retain only the observation that Vata-containing types were the most prevalent; reserve the clinical and textual significance for Discussion.
Suggested closing line for Results: "The predominance of Vata-containing Prakriti types in both groups is noteworthy in the context of the Ayurvedic understanding of Dantaharsha and will be discussed further."

Results and Observations — Key Triggers and Dietary Worseners

Figure 3 illustrates the distribution of chief stimuli triggering dentinal hypersensitivity (DH) and dietary factors reported to worsen DH, across both study groups.

(A) Triggers — DH Chief Stimulus

The most frequently reported trigger in Group A was All Stimuli — reported by 9 participants (26%), indicating sensitivity to the full range of thermal, tactile, and evaporative stimuli. In contrast, the most common trigger in Group B was Air Blast Only, reported by 12 participants (33%) — the highest single-trigger frequency observed across either group.
Cold Water and Sweet & Cold stimuli were equally distributed in Group A at 7 participants (21%) each, while in Group B both categories accounted for 7 (19%) and 5 (14%) respectively. Cold Water + Air Blast as a combined trigger was reported by 6 participants (18%) in Group A and 5 participants (14%) in Group B. Air Blast Only was the least reported trigger in Group A (5, 15%), contrasting with its predominance in Group B.
Overall, Group A showed a more distributed trigger profile with no single dominant stimulus, whereas Group B demonstrated a clear predominance of evaporative (air blast) sensitivity.

(B) Dietary Worseners — Foods Worsening DH

Cold + Citrus was the most commonly reported dietary worsener in Group A, affecting 9 participants (26%), followed by Sweet + Cold in 8 participants (24%). In Group B, Citrus Fruits was the predominant worsener, reported by 10 participants (28%), followed by Cold + Citrus in 6 participants (17%).
Citrus Fruits alone were reported by 7 participants (21%) in Group A and 10 participants (28%) in Group B. Cold Beverages worsened symptoms in 5 participants (15%) in Group A and 7 participants (19%) in Group B. Sweet + Cold as a dietary trigger was more prominent in Group A (8, 24%) compared to Group B (4, 11%).
Notably, 5 participants (15%) in Group A and 9 participants (25%) in Group B reported no specific dietary worsener, suggesting a subgroup with stimulus-only (non-dietary) hypersensitivity.

SECTION 3: AYURVEDIC SYMPTOMATIC ASSESSMENT — DANTAHARSHA RUPA/LAKSHANA SCORE

3.1 Within-Group Observations

The Dantaharsha Rupa/Lakshana Score, a validated 13-item Ayurvedic composite symptom scale, was used to assess subjective clinical presentation across four domains: Thermal & Taste Sensitivity, Mechanical Sensitivity, Pain Quality, and Local Signs. Each item was rated on a 4-point ordinal scale (0 = Absent to 3 = Severe), with a maximum aggregate score of 39. Assessments were conducted at Day 0 (baseline) and Day 30 (end of treatment).
Within-group analysis was performed using the Wilcoxon Signed-Rank test with Holm correction for multiple comparisons. The detailed parameter-wise comparison is presented in Table 3.1.
All 13 Rupa/Lakshana parameters showed statistically significant reduction from D0 to D30 in both groups (Wilcoxon Signed-Rank, all Holm-corrected p < 0.001), demonstrating that both formulations produced significant and clinically meaningful symptomatic relief across every domain of Dantaharsha.
Thermal & Taste Sensitivity: Sheeta Asahishnuta (cold sensitivity) demonstrated the greatest improvement in this domain — Group A: 1.91 → 0.56 (improvement 1.35; dz = −2.49); Group B: 2.06 → 0.72 (improvement 1.33; dz = −1.97). Amla Asahishnuta (sour sensitivity) also showed large effect sizes in both groups (dz = −1.74, Group A; −1.07, Group B).
Mechanical Sensitivity: The largest effect sizes across the entire scale were observed in this domain. Pravata Asahishnuta (air blast sensitivity) yielded dz = −2.61 in Group A and −2.21 in Group B; Sparsha Asahishnuta (touch sensitivity) yielded dz = −2.47 in Group A and −1.57 in Group B. All mechanical sensitivity parameters showed large effect sizes (|dz| > 0.80) in both groups.
Pain Quality: Ruk/Vedana (sharp pain), Toda (throbbing), Nistoda (pricking), and Charvana Vedana (pain on chewing) all demonstrated large within-group effect sizes (|dz| range: 1.09–1.94, Group A; 1.19–1.89, Group B), indicating significant reduction in qualitative pain experience in both groups.
Local Signs: Dantamula Daha (gum burning) and Mukha Daha (oral burning) showed significant improvement in both groups (dz = −0.81 and −1.09, Group A; −0.69 and −1.30, Group B respectively).
The within-group effect sizes for all 12 parameters are illustrated in Figure 3.4, and mean severity scores at D0 and D30 are depicted in Figure 3.1.

Figure 3.4 — Within-Group Effect Sizes (Cohen's dz) for all 12 parameters — Group A vs Group B. All |dz| ≥ 0.69; reference line at |dz| = 0.8

3.2 Between-Group Observations

Between-group comparison of change scores (D0 − D30) was performed using Welch's independent t-test and Mann-Whitney U test, with Holm correction for multiplicity. The results are presented in Table 3.2.
No statistically significant between-group difference was observed for any of the 13 Rupa/Lakshana parameters (all Holm-corrected p = 1.0). Hedges' g values were small across all parameters (range: −0.35 to +0.35), indicating no clinically meaningful difference in the magnitude of symptomatic relief between the two groups.
Both groups achieved mean symptom relief exceeding 60% across all four clinical domains, as depicted in Figure 3.3: Thermal/Taste Sensitivity (Group A: 70.1%; Group B: 70.5%), Mechanical Sensitivity (Group A: 73.1%; Group B: 74.0%), Pain Quality (Group A: 67.6%; Group B: 66.3%), and Local Signs (Group A: 76.1%; Group B: 81.6%).
The parameter-wise improvement scores are illustrated in Figure 3.2, which confirms broadly comparable relief profiles across both groups with no parameter showing inter-group superiority.

what does mean by dz

Cohen's d_z — Explained Simply

dz is a measure of effect size for paired/within-group data.

What it measures

It tells you how large the change was within a single group — not just whether the change was statistically significant, but how meaningful it was in practical/clinical terms.

The formula

dz = Mean Difference (D0 − D30) ÷ Standard Deviation of the Differences
In plain language:
"How many standard deviations did the score change by?"

Why "z" in dz?

The "z" stands for the difference scores (each participant's individual change = D0 − D30). Cohen's dz is specifically computed from those difference scores — distinguishing it from Cohen's d used for independent groups.

How to interpret the value

| |dz| value | Interpretation | |---|---|---| | 0.2 | Small effect | | 0.5 | Medium effect | | ≥ 0.8 | Large effect | | ≥ 2.0 | Very large / exceptional effect |

In your study — practical example

Pravata Asahishnuta (air blast sensitivity), Group A: dz = −2.61
This means the score dropped by 2.61 standard deviations from baseline to Day 30. That is an exceptionally large treatment effect — not just statistically significant, but clinically very meaningful.
The negative sign simply indicates the score went down (improvement), since lower score = less severity.

Why it matters for your thesis

Reporting dz alongside p-values strengthens your results because:
  • A p-value only says "the change is real"
  • dz says "the change was large/small/negligible"
  • In a study with n = 34–36, large dz values confirm the treatment effect is clinically significant, not just a statistical artefact of sample size.

SEM Tubule Occlusion: PRE vs POST (Ordinal Scale) — Non-parametric Analysis Outcome is an ordinal 5-point scoring scale. Therefore, non-parametric tests are used throughout: Wilcoxon signed-rank for within-group paired PRE vs POST, and Mann–Whitney U for between-group comparisons. Effect sizes are reported as r (Wilcoxon) and rank-biserial correlation r for Mann–Whitney. Ten paired observations per group were matched by position (Tooth 1 to 10). Table 1.

The change score (PRE−POST) also differs significantly between groups, consistent with a larger improvement in Group 1 for the extracted ranges.provide me writeup for sem and tables n images of comparison results n observations

SECTION 5: SEM TUBULE OCCLUSION ANALYSIS — PRE vs POST

Methodology Note

Dentinal tubule occlusion was assessed using Scanning Electron Microscopy (SEM) on extracted tooth specimens. Occlusion scores were recorded on a validated 5-point ordinal scale (0 = no occlusion; 5 = complete occlusion — lower post-treatment score = better occlusion). Ten paired specimens per group (Tooth 1 to Tooth 10) were matched by position. Given the ordinal nature of the outcome, all analyses were conducted using non-parametric tests: Wilcoxon Signed-Rank test for within-group PRE vs POST comparisons and Mann–Whitney U test for between-group comparisons. Effect sizes are reported as r (Wilcoxon) and rank-biserial correlation r (Mann–Whitney).

5.1 Within-Group Observations

The PRE and POST scores for all ten specimens in each group are presented in Table 1, and the within-group statistical comparison is summarised in Table 3.
Group 1 (Potassium Nitrate — KNO₃): The median PRE score was 4.60 (IQR: 4.487–4.688), indicating near-maximum baseline hypersensitivity with minimal tubule occlusion. Following treatment, the median POST score reduced significantly to 2.10 (IQR: 2.025–2.175), representing a median change of 2.45 score units across the ten specimens. The Wilcoxon Signed-Rank test yielded W = 0.0, p = 0.0020, with a large effect size of r = 0.886, confirming highly significant and clinically meaningful tubule occlusion after treatment.
Group 2 (Ayurvedic — Yashtimadhvadi): The median PRE score was 4.50 (IQR: 4.45–4.638), comparable to Group 1 at baseline. The median POST score was 2.60 (IQR: 2.3–2.8), with a median change of 2.00 score units. The Wilcoxon test similarly yielded W = 0.0, p = 0.0020, with an identical large effect size of r = 0.886, confirming statistically significant and substantial tubule occlusion with the Ayurvedic formulation as well.
Both groups thus demonstrated highly significant within-group improvement in tubule occlusion following treatment, with large effect sizes in both cases (Figure SEM-1, Figure SEM-2).

5.2 Between-Group Observations

Between-group comparisons were performed on both POST scores and change scores (PRE − POST), as presented in Table 4.
POST Scores — Group 1 vs Group 2: The POST median score of Group 1 (2.10) was significantly lower than that of Group 2 (2.60) (Mann–Whitney U = 8.0, p = 0.0015, rank-biserial r = 0.84). A lower POST score indicates superior tubule occlusion; this finding therefore confirms that Group 1 (KNO₃) achieved significantly greater final tubule occlusion at Day 30 compared to Group 2. The large effect size (r = 0.84) confirms this is a clinically meaningful difference (Figure SEM-4).
Change Scores (PRE − POST) — Group 1 vs Group 2: The median change score was 2.45 in Group 1 and 2.00 in Group 2 (Mann–Whitney U = 89.0, p = 0.0036, rank-biserial r = −0.78). The negative rank-biserial r indicates that Group 1 change scores were systematically larger — i.e., Group 1 achieved a greater magnitude of occlusion improvement across all paired specimens. The effect size (|r| = 0.78) approaches the large threshold and is clinically significant (Figure SEM-3).

Both formulations produced statistically significant and large-effect tubule occlusion at Day 30. Between-group analysis demonstrated that Group 1 (KNO₃) achieved superior tubule occlusion both in terms of final POST score and magnitude of change, with large effect sizes on both comparisons. These SEM findings are consistent with and corroborate the superior VAS and Schiff score reductions observed for Group 1 in the clinical sensitivity outcomes (Section 4).

Note on SEM score direction: Throughout the write-up, lower POST score = better tubule occlusion — this is clearly annotated on all graphs. Confirm with your guide whether the scale in your study runs 0→5 (none→complete) or 5→0 (none→complete) and adjust the axis labels in the script accordingly if needed.
