Persistent periodontal inflammation before restorative work

An adult presents for replacement of a damaged posterior crown and asks for a rapid cosmetic solution. The medical history includes smoking and diabetes, but no recent information about glycemic control is available. Examination finds generalized plaque, several bleeding sites, recession, and a localized deep measurement near the proposed crown. The patient says the tooth has never hurt and assumes this proves the supporting tissues are healthy. An older periodontal chart and radiographs are available but have not yet been compared with the current findings. The existing restoration has a contour that makes interdental cleaning difficult. The clinician must distinguish historical attachment loss, current inflammation, and a possible local restorative contribution before committing to a new margin or a surgical procedure.

1. What information should be integrated before choosing periodontal and restorative treatment?

Read the worked answer

Compare probing depth, gingival-margin position, attachment levels, bleeding, bone levels, mobility, furcation findings, and the previous records. Assess plaque access and the restoration contour, clarify smoking and glycemic status, and consider the tooth prognosis and patient priorities. Lack of pain does not establish periodontal health.

2. Outline a reasoned sequence rather than selecting an invasive procedure from one deep measurement.

Address modifiable biofilm and local retentive factors, provide practical self-care instruction, and coordinate relevant medical information. Reassess the tissue response before deciding whether additional periodontal treatment or a changed restorative design is needed. Plan a margin and contour compatible with supporting tissues and maintenance.
