Abstract

Background: Adults with autism spectrum disorder (ASD) often face substantial barriers in receiving routine dental care, resulting in unmet oral health needs, untreated caries, and episodic dental pain. Literature reports increased dental anxiety, sensory hypersensitivity, limited tolerance to clinical procedures, and dependence on caregivers, especially in males with severe behavioural expression.

Case Presentation: A 28-year-old adult male with ASD residing in Mumbai presented with severe dental pain and inability to cooperate during examination. Behavioural challenges included hyperactivity, non-verbal communication patterns, and inability to tolerate intraoral procedures. Based on risk assessment and predicted lack of cooperation, treatment was planned under general anaesthesia (GA). A full-mouth rehabilitation was executed: Root canal therapy and post placement for the right upper molars, also root canal therapy for right lower first molar, extraction, and immediate implant placement for the left upper and lower first molars, and prefabricated crowns placed intraoperatively. Procedure and recovery were uneventful; patient was discharged two hours post-op. At one-week review, the family reported no pain or complications. At a six-month teleconsultation, the patient was asymptomatic and functioning well.

Conclusion: This case demonstrates the importance of providing timely and comprehensive dental treatment under GA for adults with ASD who cannot cooperate with conventional care. Early intervention, caregiver collaboration, and appropriate behaviour-based planning can prevent progression to dental emergencies. The report reinforces the message that general practitioners and specialists should confidently manage special-needs patients with structured protocols.

Introduction

Autism spectrum disorder (ASD) is associated with distinctive behavioural, sensory, and communication characteristics that significantly influence dental care delivery. Adults with ASD, even those with adequate family support, often present with elevated dental fear, reduced attendance, untreated caries, and reliance on emergency-driven treatment (Blomqvist et al., 2015). Many studies show that adult autistic individuals exhibit heightened sensory reactivity, difficulty adapting to change, and poor tolerance for tactile, auditory, and visual stimuli encountered in the dental setting (Limeres-Posse et al., 2014; Chandrashekhar et al., 2018).

Barriers include communication challenges, behavioural dysregulation, limited desensitisation, and inadequate training of dental practitioners (Jones et al., 2024; Prynda et al., 2024). For patients who cannot tolerate routine care, treatment under general anaesthesia (GA) remains evidence-based and safe (Son et al., 2024; Czornobay et al., 2018). This case presents the comprehensive management of a 28-year-old autistic adult requiring simultaneous restorative, endodontic, and implant procedures.

Case Description

Patient Background

A 28-year-old autistic male residing in Mumbai, living with family and caretakers at a farmhouse in Lonavala, presented with acute dental pain and marked behavioural hyperactivity. He was non-verbal with limited comprehension, highly uncooperative with touch, and unable to sit still for examination. Caregivers reported disturbed sleep due to pain.

Clinical & Radiographic Findings

Although chairside examination was restricted, the patient permitted an OPG radiograph shown in Figure 1a , which revealed pathology involving all four first molars. Findings included:

  • #16 – Fractured crown with pain and sensitivity.
  • #14 – Deep Caries
  • #15, #11, #12 – Proximal Caries
  • #26, #36 – Root piece (Figure 2a and 2b)
  • #46 – Root canal treated tooth with chronic periapical pathology

Behavioural Assessment

Multiple indicators confirmed that conventional treatment would be impossible, including:

  • Extreme hyperactivity
  • Inability to communicate pain
  • Sensory defensiveness
  • Zero tolerance to instruments or touch
  • High distress in clinical environment

These align with contemporary literature documenting behavioural dysregulation, sensory overload, and dental fear in adults with ASD (Blomqvist 2015; Pastore 2023; Prynda 2024).

Treatment Planning

Given behavioural challenges and multi-quadrant disease, a single-stage, comprehensive care approach under GA was planned, consistent with recommendations for patients with severe ASD (Limeres-Posse et al., 2014; Son et al., 2024).

The plan included:

Oral Prophylaxis

Fillings - #15, #11, #12

Root Canal Therapy - #16, #46, #14 (Figure 3)

Extraction - #26, #36

Implants - #26, #36

Prefab Prosthesis - #14, #16, #26, #36, #46 (Figure 4).

Treatment Under General Anaesthesia

Anaesthetic Protocol

Patient was intubated via the right naso-endotracheal tube. GA was induced and maintained uneventfully.

 The procedure lasted approximately 90 minutes.

Intraoperative Workflow

  • Oral Prophylaxis
  • Fillings - #12
  • Root Canal Therapy - #14, #16, #46, 
  • Extraction - #26, #36
  • Implants - #26, #36
  • Prefab Prosthesis - #14, #16, #26, #36, #46
  • Occlusion adjusted to reduce high contacts, considering the patient's bruxism tendencies common in ASD adults (Prynda 2024).

Recovery

Patient recovered smoothly and was discharged 2 hours post-operatively. Caregivers received instructions on analgesia, soft diet, and implant hygiene.

Follow-Up

1-Week Review (In-Person)

Post operative radiograph was taken in the follow up appointment as shown in ‘Figure 1b’

Family reported:

  • No pain
  • Good acceptance of food
  • No distress or behavioural changes

Clinical evaluation showed:

  • Stable healing
  • No inflammation
  • Good crown retention

6-Month Follow-Up (Virtual Consultation)

Due to difficulty transporting the patient, teleconsultation was used. Caregivers reported:

  • No pain or swelling
  • Normal eating habits
  • Restored comfort and sleep
  • No prosthesis-related issues

This aligns with literature supporting tele-dentistry for ASD patients with travel limitations (Floríndezet al., 2024).

Discussion

Adults with ASD frequently experience unmet oral health needs due to behavioural challenges, sensory sensitivities, and systemic access barriers (Jones et al., 2024). Dental avoidance is common, often leading to emergency-based care, similar to the present case (Blomqvist 2015). Behavioural manifestations in ASD—hyperactivity, reduced attention, and distress during unfamiliar stimuli—limit tolerance to routine procedures (Czornobay 2018; Pastore 2023).

When non-pharmacologic methods fail or multiple complex procedures are required, GA becomes the safest modality. Evidence shows it results in high caregiver satisfaction, allows comprehensive care, and prevents repeated traumatic encounters (Son et al., 2024).

Given difficulty returning for sit-down appointments, durable options—RCT with posts and prefabricated crowns, and implant-supported rehabilitation—are ideal. Simplification and reduction of future treatment burden are recommended in adults with ASD (Zerman 2022).

The family’s stable support structure significantly contributed to postoperative recovery, aligning with studies showing caregiver-facilitated routines improve outcomes (Floríndez 2024).

The case reinforces that general dentists and specialist should not hesitate to treat ASD adults when a structured approach is used. A combination of:

  • Adequate preoperative planning
  • Behavioural assessment
  • Sensory-friendly interactions
  • Use of GA when required
  • Long-term follow-through via teleconsultations

can achieve predictable, complication-free outcomes.

This case adds to literature encouraging wider acceptance of ASD patients in mainstream dental practice and underscores the value of GA-supported comprehensive treatment in adults with severe behavioural limitations.

Conclusion

This report highlights the successful rehabilitation of a 28-year-old autistic adult using a single-stage same day dentistry approach, comprehensive approach under GA. The outcome demonstrates that with careful planning, empathetic caregiver collaboration, and appropriate behavioural considerations, dentists can deliver effective and humane care even for non-cooperative ASD patients. The case supports broader training and confidence among dental professionals to treat individuals with special needs.
