The Problem

Initial Condition

The patient was referred to Dr Ridhwan Ahmed with a long-standing sinus tract and persistent pus discharge associated with a heavily broken-down and decayed lower left first molar (LL6).

Root canal treatment had previously been attempted on two separate occasions by two different dentists, but due to the complexity of the tooth, the patient was subsequently referred to Dr Ridhwan for specialist endodontic treatment.

Treatment Plan

Why was this case complex?

The tooth presented with a severe 90-degree curvature near the end of the root, making the canals particularly challenging to negotiate safely. The patient also had limited mouth opening, making access to the tooth more difficult.

 

Treatment

Using advanced endodontic techniques, Dr Ridhwan was able to successfully navigate the severely curved root canal anatomy and complete the root canal treatment.

Despite the complexity of the case, treatment was successfully completed in a single appointment.

Severe Root Curvature

A 90-degree curvature near the end of the root made the canals particularly challenging to negotiate safely.

Limited Mouth Opening

Restricted access made treatment of the lower left first molar more difficult.

Advanced Endodontic Treatment

Dr Ridhwan successfully navigated the curved canal anatomy and completed treatment in a single appointment.

Transformation Results

A remarkable transformation achieved with precision and personalized care.

X-RAY 6 MONTH REVIEW
The Result

Complete Healing at 6 Months

At the six-month review, there was complete clinical resolution of the infection, with no further sinus tract or pus discharge.

The follow-up X-ray also demonstrated complete healing around the roots. The dark area previously visible around the ends of the roots, representing infection and bone loss, had completely resolved.

No sinus tract

Fully resolved at review

No pus discharge

Infection clinically cleared

Complete root healing

X-ray showed full recovery

This case demonstrates that even teeth with severely curved root canals and previous unsuccessful treatment attempts can sometimes be successfully treated and retained with advanced endodontic care.
