THE SILENT EPIDEMIC – ADDRESSING BURNOUT IN THE DENTAL COMMUNITY

2025-06-19T08:59:15+00:00

Burnout among dental professionals is a growing concern worldwide, but in regions like Pakistan and particularly Khyber Pakhtunkhwa, it remains largely underrecognized and underreported. The dental profession demands high levels of concentration, manual dexterity, and continuous patient interaction, often in resource-limited and high-stress environments. In KP’s public and teaching hospitals, dentists face large patient loads, outdated equipment, and administrative burdens that significantly contribute to emotional exhaustion and depersonalization key hallmarks of professional burnout. Coupled with the stigma around mental health and limited institutional support, this silent crisis continues to erode the wellbeing of our dental workforce.

The implications of burnout go beyond individual suffering. Studies have shown that it directly impacts quality of care, patient safety, and even academic productivity in teaching institutions. In the context of Khyber Pakhtunkhwa, where dental services are stretched thin across urban and rural divides, the consequences of an overburdened and disengaged dental workforce could lead to long-term public health repercussions. Young dentists, house officers, and postgraduates in particular often face unrealistic expectations, poor mentorship, and job insecurity all of which increase susceptibility to early career burnout.

It is imperative that academic institutions, hospital administrators, and policymakers prioritize the mental health of dental professionals. Preventive strategies such as workload redistribution, mental health literacy programs, institutional counselling support, and protected academic time must be urgently introduced. Furthermore, integrating burnout screening and resilience training into dental curricula could empower future professionals to recognize and manage stress proactively. If left unaddressed, burnout will continue to undermine not only the profession but also the trust and care we owe our communities.

CORRELATION BETWEEN MOTORCYCLE RIDING BEHAVIORS AND SEVERITY OF MAXILLOFACIAL INJURIES IN PESHAWAR, KHYBER PUKHTUNKHWA

2025-06-03T06:33:22+00:00

Objective: The objective of this study is to determine the correlation between riding behavior score of motorcyclists and maxillofacial injuries severity score.

Methodology: This co relational Cross sectional study was conducted in the Department of Oral & Maxillofacial Surgery at Khyber College of Dentistry Peshawar from June 2022 to December 2024 on 264 patients who suffered Oral & Maxillofacial injuries as a result of motorcycle riding. Data was collected on a pre-validated Modified Motorcycle Rider Behavior Questionnaire & Facial Injury Severity Score. Categorical variables such as pattern of fracture (injury type), Educational Level, SES, addiction, registration status, accidents in the past, occupation and driving experience were expressed in terms of frequency and percentage while continuous variables such as age, MRBQ score and FISS was expressed as mean ± standard deviation (SD). Mean MRBQ score and Mean FISS were correlated using Pearson correlation. P<0.05 was considered statistically significant.

Results: The Facial Injury Severity Score had a mean of 1.89 ± 0.69 SD while Motorcycle Riding Behaviour Score had a mean of 1.97 ± 0.65 SD, showed a strong positive Pearson correlation of 0.847, statistically significant at the p < 0.001 level. The motorcycle riding behaviour score was strongly and positively correlated with both traffic errors score (r = 0.83) and facial injury severity score (r = 0.83). Stunts score showed a moderate positive correlation with the motorcycle riding behaviour score (r = 0.33) and facial injury severity score (r = 0.38. Control error score demonstrated moderate negative correlations with both the motorcycle riding behaviour score (r = –0.29) and facial injury severity score (r = –0.36. The number of accidents in the past had a weak-to-moderate positive association with stunts score (r = 0.56) and facial injury severity score (r = 0.35).

Conclusion: These findings underscore the urgent need for targeted interventions focused on young motorcyclists, including road safety education, strict enforcement of traffic laws, and promotion of helmet use to reduce the incidence and severity of maxillofacial injuries.

2025-03-08T07:42:34+00:00

Objectives:

The objective of the study was to highlight a disinfectant which dentists can use to decontaminate alginate impressions in hospitals and clinics before sending it to laboratory.

Materials and Methods:

This In-vitro experimental study was conducted at the Department of Prosthodontics, Sardar Begum Dental College & Hospital, Peshawar. After Ethical approval Microbiological analysis were carried out at Research Centre Gandhara University, Peshawar. Consent was taken from Male dentate individuals fulfi lling the inclusion criteria and maxillary impressions were achieved from them. Palatal portion each impression was divided into four section. Specimens of control group 1 were left unwashed and
untreated whereas; Specimens of experimental group 2 were sprayed with simple tap water, specimens of experimental group 3 were washed with 0.5% hypochlorite solution and specimens of experimental group 4 were treated with 1% chlorohexidine solution. These specimen were then arranged on blood agar petriplates stitched with S.mutans and results were collected. For dimensional stability specimen were made from alginate impression materials and were tested according to ADA specification no 19.

Results:

The control group (untreated) exhibited the highest mean microbial colony count (63.6 ± 15.1 CFU), while disinfection with 1% chlorhexidine resulted in the lowest (1.27 ± 1.53 CFU), refl ecting a 98% reduction in microbial load (p < 0.001). Treatment with 0.5% sodium hypochlorite also showed a signifi cant reduction (2.2 ± 1.90 CFU; p < 0.001, 96.5% reduction), whereas rinsing with tap water (19.87 ± 6.78 CFU) achieved only a 68.8% reduction (p < 0.001). In terms of dimensional stability, untreated impressions showed a 10%
reduction in dimensions after 1 hour (from 20 mm to 18 mm). In contrast, the 1% chlorhexidine group maintained dimensional stability with only a 2.5% change (20 mm to 19.5 mm), followed by 0.5% hypochlorite (4.5%) and tap water (4%). All changes were statistically significant (p < 0.05), with 1% chlorhexidine showing the most favorable balance of antimicrobial effi cacy and minimal dimensional distortion.

Conclusion:

Chlorohexidine 1% is proved to be a potent disinfectant as compared to tap water and 0.5% sodium hypochlorite for irreversible hydrocolloid alginate impression material.

2025-06-06T05:08:05+00:00

Objectives: To evaluate in vitro the effect of three different thicknesses of traditional fibre posts and a novel canal post (bundle post) on the fracture resistance of restored teeth.
Materials and Methods: Ninety-two extracted single-rooted, single-canaled upper incisors were selected and prepared for endodontic treatment. The specimens were divided into six experimental groups (n=14 each) based on post type and thickness: Group I (Bundle Post 0.8 mm), Group II (Bundle Post 1 mm), Group III (Bundle Post 1.2 mm), Group IV (Fibre Post 0.8 mm), Group V (Fibre Post 1 mm), and Group VI (Fibre Post 1.2 mm). Additionally, two control groups were included: a negative control group (n=4, untreated healthy teeth) and a positive control group (n=4, canal prepared but unrestored). Fracture resistance was tested using an Instron device, and results were analyzed statistically.
Results: The negative control group showed the highest fracture resistance (2133.21 ± 317.42 N), significantly greater than the positive control group (1436.08 ± 334.31 N; p < 0.05). Among experimental groups, no statistically significant differences were observed based on post type or thickness (p > 0.05). For 0.8 mm posts, fracture resistance was 1211.14 ± 396.85 N (bundle) and 1276.42 ± 339.02 N (fibre); for 1 mm posts, 1355.49 ± 282.45 N (bundle) vs. 1271.86 ± 323.46 N (fi bre); and for 1.2 mm posts, 1122.74 ± 311.50 N (bundle) vs. 1062.49 ± 163.10 N (fibre), all with p > 0.05.
Conclusion: The fracture resistance of teeth restored with bundle fibre posts of varying thicknesses was comparable to those restored with conventional fibre posts.

Objectives: This study's objective is to evaluate the immunoreactivity of MMP-9 in tissue samples from diagnosed cases of oral precancerous conditions and from normal oral mucosa.
Materials and Methods: This study evaluated MMP-9 immunoreactivity in normal oral mucosa and oral potentially malignant disorders (OPMDs). Tissue samples were collected from surgical procedures and departmental archives, with H&E and immuno-histochemical staining performed following standard protocols. Immunoreactivity was assessed based on staining intensity and positive cell percentage, using spleen tissue as a positive control. Statistical analysis showed signifi cant differences in age between normal mucosa and OPMD cases (p < 0.05).
Results: MMP-9 expression was high in OPMDS patients than in normal oral mucosa. While comparing the degree of MMP-9 expression among OPMDs and normal oral mucosa , a statistically significant relationship was found.
Conclusion: MMP-9 expression was shown to be higher in OPMDs than in normal oral mucosa. Evaluation of MMP-9 biomarker may be clinically significant in OPMDs and may be utilized as a diagnostic indicator for OPMDs.

CLINICOPATHOLOGICAL ANALYSIS AND CD44 EXPRESSION IN ORAL AND OROPHARYNGEAL SQUAMOUS CELL CARCINOMA

2025-06-05T06:53:08+00:00

Objectives: To assess the relationship between CD44 expression in malignant cells, clinicopathological findings, and prognostic outcomes in oral squamous cell carcinoma.
Materials and Methods: This was a retrospective comparative study utilized excisional and incisional biopsy specimens from oral and oropharynx, collected at Akbar Niazi Teaching Hospital, Islamabad, between September 2022 and September 2024. Among 40 specimens, 13 were well-differentiated, 19 were moderate, and 8 were poor squamous cell carcinomas, with or without nodes metastasis. These specimens were randomly selected for CD44 immunohistochemical staining.
Results: The majority of patients were between 50 and 75 years old (mean was 62.5±7.2 years), and males were 77.5%. The mean tumor depth was 0.7±0.4 mm. T1 tumors were the most common (55%), with the majority exhibiting N0 nodal status (62.5%). Grade 2 tumors were the most frequent (47.5%), while stage I tumors had the highest prevalence (40%). Strong CD44 expression was detected in 72.5% cases, with basal cell invasion present in 55%. Lesions were most frequently located on the tongue (30%) and vocal cords (25%). Insignificant difference was observed in age, gender, tumor size, nodal status, or basal cell invasion across expression levels (p > 0.05). A notable variation in tumor grades was identified across different expression levels (p = 0.022).
Conclusion: Reduced CD44 expression in aggressive OSCC, characterized by poor differentiation and lymphnode involvement, indicates a potential association with disease progression. CD44 may help preserve tissue structure, and its loss could serve as a potential marker of poor prognosis.
