Which treatment is preferable for a cavity found on tooth 75?

The preferable treatment for a cavity found on tooth 75, which is designated as a primary molar, is to perform a pulpotomy followed by restoration. A pulpotomy involves removing the diseased pulp tissue from the crown of the tooth while preserving the vitality of the remaining pulp tissue in the roots. This procedure is particularly common in pediatric dentistry when dealing with cavities in primary teeth, as it allows the tooth to be maintained and function until it naturally exfoliates.

Restoration follows the pulpotomy to seal the tooth and protect it from further decay. This approach is preferred because it not only addresses the cavity but also retains the tooth, which is crucial in maintaining the proper alignment and spacing of the developing teeth. Preserving the primary molar is vital for the child’s overall dental health, as these teeth play a significant role in chewing and can influence the eruption of permanent teeth.

The other options either involve more invasive procedures or are not suitable for a cavity in a primary tooth. Extraction and implant placement are not typically recommended for primary teeth since they are destined to fall out naturally. Fixed bridges are also inappropriate in this scenario because they are used to replace missing teeth and require the alteration of adjacent healthy teeth. Watchful waiting may be considered
